Hybrid Solar Lighting - Fiber Optics Brings Sunlight Inside  

Science Conference Proceedings (OSTI)

Hybrid solar lighting systems focus highly concentrated sunlight into a fiber optic bundle to provide sunlight in rooms without windows or conventional skylights. The flexible sunlight bundles are easily routed through small openings and around obstacles to carry the light to where it is needed. The optical fibers terminate in hybrid luminaires where the sunlight is combined with electric light that is automatically adjusted to keep the overall light level constant within the lighted area. The hybrid solar lighting concept was originally proposed at Oak Ridge National Laboratory in Tennessee in the mid-1990s, but funding hurdles prevented the idea from seeing daylight for more than five years. Hybrid solar lighting was touted as a means for using solar energy directly without any conversion losses and for increasing the visual quality of interior lighting. As such, it promised to be both energy-efficient and aesthetically appealing, but its technical complexity made potential sponsors wary. They had to be convinced that the lighting concept could be accepted into the marketplace and that the systems could be manufactured at an acceptable cost. An earlier fiber-coupled daylighting system marketed in the early 1990s used expensive quartz optical fibers to distribute the light and served only a niche market that was willing to pay a premium for the novelty. By contrast, the hybrid solar lighting system proposed using inexpensive plastic optical fibers to distribute the light to hybrid (sunlight/electric) luminaires that would be visually and functionally identical to conventional luminaires. In this way, the lighting could be integrated seamlessly into existing design concepts and thus easily embraced by architects and lighting designers as a means for offering daylight as a lighting option.

Sunlight Responsive Thermochromic Window System  

SciTech Connect

Pleotint has embarked on a novel approach with our Sunlight Responsive Thermochromic, SRT, windows. We are integrating dynamic sunlight control, high insulation values and low solar heat gain together in a high performance window. The Pleotint SRT window is dynamic because it reversibly changes light transmission based on thermochromics activated directly by the heating effect of sunlight. We can achieve a window package with low solar heat gain coefficient (SHGC), a low U value and high insulation. At the same time our windows provide good daylighting. Our innovative window design offers architects and building designers the opportunity to choose their desired energy performance, excellent sound reduction, external pane can be self-cleaning, or a resistance to wind load, blasts, bullets or hurricanes. SRT windows would provide energy savings that are estimated at up to 30% over traditional window systems. Glass fabricators will be able to use existing equipment to make the SRT window while adding value and flexibility to the basic design. Glazing installers will have the ability to fit the windows with traditional methods without wires, power supplies and controllers. SRT windows can be retrofit into existing buildings,

Fullerenes produced by harnessing sunlight  

Science Conference Proceedings (OSTI)

Two independent groups of researchers have demonstrated that fullerenes can be produced by harnessing focused sunlight to vaporize carbon. Adapted to a large scale, generation of the carbon-cage molecules in solar furnaces might overcome yield-limiting problems associated with other fullerene production techniques, the researchers suggest. At Rice University, Houston, chemistry professor Richard E. Smalley and graduate students L.P. Felipe Chibante, Andreas Thess, J. Michael Alford, and Michael D. Diener used a parabolic mirror to focus sunlight on a graphite target to produce what appears to be a high yield of fullerenes. At the National Renewable Energy Laboratory (NREL), Golden, Colo., Roland R. Pitts, Mary Jane Hale, Carl Bingham, Allan Lewandowski, and David E.King, working in collaboration with Clark L. Fields, a chemistry professor at the University of Northern Colorado, Greeley, used NREL's high-flux solar furnace to produce soot that contains C[sub 60] and C[sub 70]. Papers describing the Rice and NREL results appeared together in last week's Journal of Physical Chemistry (97, 8696 and 8701 (1993)).

Efficient Solar Concentrators: Affordable Energy from Water and Sunlight  

Science Conference Proceedings (OSTI)

Broad Funding Opportunity Announcement Project: Teledyne is developing a liquid prism panel that tracks the position of the sun to help efficiently concentrate its light onto a solar cell to produce power. Typically, solar tracking devices have bulky and expensive mechanical moving parts that require a lot of power and are often unreliable. Teledynes liquid prism panel has no bulky and heavy supporting partsinstead it relies on electrowetting. Electrowetting is a process where an electric field is applied to the liquid to control the angle at which it meets the sunlight above and to control the angle of the sunlight to the focusing lensthe more direct the angle to the focusing lens, the more efficiently the light can be concentrated to solar panels and converted into electricity. This allows the prism to be tuned like a radio to track the sun across the sky and steer sunlight into the solar cell without any moving mechanical parts. This process uses very little power and requires no expensive supporting hardware or moving parts, enabling efficient and quiet rooftop operation for integration into buildings.

Energy from Water and Sunlight: Affordable Energy from Water and Sunlight  

SciTech Connect

Broad Funding Opportunity Announcement Project: Sun Catalytix is developing wireless energy-storage devices that convert sunlight and water into renewable fuel. Learning from nature, one such device mimics the ability of a tree leaf to convert sunlight into storable energy. It is comprised of a silicon solar cell coated with catalytic materials, which help speed up the energy conversion process. When this cell is placed in a container of water and exposed to sunlight, it splits the water into bubbles of oxygen and hydrogen. The hydrogen and oxygen can later be recombined to create electricity, when the sun goes down for example. The Sun Catalytix device is novel in many ways: it consists primarily of low-cost, earth-abundant materials where other attempts have required more expensive materials like platinum. Its operating conditions also facilitate the use of less costly construction materials, whereas other efforts have required extremely corrosive conditions.

Sensitized photoelectrolysis of water with sunlight. Final report, June 1, 1977-December 31, 1978  

SciTech Connect

A study was made of solar driven water photoelectrolysis cells employing semiconductor electrodes. An extensive review of the literature was undertaken, and the three major problem areas for these devices were identified: corrosion, poor sunlight absorption, and external bias requirement. Although many semiconductors had been tested, none had proven free of all three defects. Two approaches were thus followed for the experimental studies: impurity sensitization of wide band gap stable oxides, and heterostructure formation between unstable sunlight absorbers and corrosion resistant oxides. Water decomposition was achieved with visible light excitation of Cr-doped TiO/sub 2/. Transport properties were studies for TiO/sub 2/ and SrTiO/sub 3/ electrodes doped with V, Cr, Mn, Fe, Co, and Ni. The correlation between bias requirement and electron affinity of oxides was identified. Performance of heterostructure electrodes was shown to be limited either by pin hole problems or by potential barriers between the valence bands.

Since lighting accounts for about one-third of the energy used in commercial buildings, there is opportunity to conserve. There are two ways to reduce lighting energy use: modify lighting systems so that they used less electricity and/or reduce the number of hours the lights are used. This booklet presents a number of ways to do both. Topics covered include: reassessing lighting levels, reducing lighting levels, increasing bulb & fixture efficiency, using controls to regulate lighting, and taking advantage of daylight.

The lighting section of ASHRAE standard 90.1 is discussed. It applies to all new buildings except low-rise residential, while excluding specialty lighting applications such as signage, art exhibits, theatrical productions, medical and dental tasks, and others. In addition, lighting for indoor plant growth is excluded if designed to operate only between 10 p.m. and 6 a.m. Lighting allowances for the interior of a building are determined by the use of the system performance path unless the space functions are not fully known, such as during the initial stages of design or for speculative buildings. In such cases, the prescriptive path is available. Lighting allowances for the exterior of all buildings are determined by a table of unit power allowances. A new addition the exterior lighting procedure is the inclusion of facade lighting. However, it is no longer possible to trade-off power allotted for the exterior with the interior of a building or vice versa. A significant change is the new emphasis on lighting controls.

Mn4Ca Structure. (click on image for diagram portraying the water-splitting catalytic cycle) Mn4Ca Structure. (click on image for diagram portraying the water-splitting catalytic cycle) Scientific Highlight LBNL Press Release Physical Biosciences, LBNL 30 November 2006 Learning How Nature Splits Water (Condensed by Brad Plummer from a press release issued by Lawrence Berkeley National Laboratory) Billions of years ago, primitive bacteria developed a way to harness sunlight to split water molecules into protons, electrons and oxygen-the cornerstone of photosynthesis. Now, a team of scientists has taken a major step toward understanding this process by deriving the precise structure of the catalytic metal-cluster center containing four manganese atoms and one calcium atom (Mn4Ca) that drives this water-splitting reaction. This catalytic center resides in a large protein complex, called photosystem II, found in plants, green algae, and cyanobacteria. The international team was led by scientists from LBNL, and includes scientists from Germany's Technical and Free Universities in Berlin, the Max Planck Institute in Mülheim, and from SSRL.

Simplified calculational procedure for determining the amount of intercepted sunlight in an imaging solar concentrator  

Science Conference Proceedings (OSTI)

In imaging solar concentrators, the solar radiation incident on a receiver surface depends upon both the overall concentrator shape and the angular distribution of light rays (sunshape) that reach the receiver. Calculation of the amount of sunlight incident on the receiver usually requires sophisticated computer programs. A simplified calculational procedure is presented to solve this problem for both one- and two-dimensional concentrators, with the results presented in graphical form. The procedure first determines the amount of sunshape broadening resulting from optical scattering caused by reflector or glazing materials, surface slope errors, or other ''mechanical'' factors such as tracking errors or vibrations. These optical effects are combined into an effective error cone which is convoluted with measured sunshapes in order to obtain effective, broadened sunshapes. Broadened sunshapes for a variety of effective error-cone distributions are calculated and presented. It is found that when the root-mean-square (RMS) width of the effective error cone is greater than approximately two times the RMS width of the incident sunshape, the broadened sunshape can be adequately described by a circular normal distribution. A specific example is included which illustrates the calculational procedure discussed in the paper.

Terrestrial photovoltaic power systems with sunlight concentration. Annual progress report, January 1, 1975--December 31, 1975  

DOE Green Energy (OSTI)

This annual report is for the second year of a program to investigate the characteristics of the components and the total system using sunlight concentrated onto solar cells. The second year was primarily to experimentally investigate the conclusions of the first year of analytical studies. Cells have been fabricated that are designed for different intensities. Typically the efficiency of a cell will increase from its 11 percent at AM1 peak to efficiency at the designed concentration level and return to its initial efficiency at about 3 times its designed concentration level. The developed cells have been tested under high intensity simulators and in concentrated sunlight and have shown to have the predicted response. The experimental testing of passive cooling limitations for cooling cells with just finned arrangements in the back of the cell has been completed in the controlled environment of a wind tunnel. These experiments have confirmed the heat transfer coefficients that had been used in the analytical studies. Testing was done to collect heat transfer coefficients for actual wind conditions and these data show good agreement with the controlled wind tunnel data. Four photovoltaic/concentrator system experiments have been started with CR of about 3, 10, 25, and 100. System analysis has indicated that photovoltaic concentration systems may be attractive in low solar irradiation areas such as Cleveland.

Design and Analysis of Hybrid Solar Lighting and Full-Spectrum Solar Energy Systems  

DOE Green Energy (OSTI)

This paper describes a systems-level design and analysis of a new approach for improving the energy efficiency and affordability of solar energy in buildings, namely, hybrid solar lighting and full-spectrum solar energy systems. By using different portions of the solar spectrum simultaneously for multiple end-use applications in buildings, the proposed system offers unique advantages over other alternatives for using sunlight to displace electricity (conventional topside daylighting and solar technologies). Our preliminary work indicates that hybrid solar lighting, a method of collecting and distributing direct sunlight for lighting purposes, will alleviate many of the problems with passive daylighting systems of today, such as spatial and temporal variability, glare, excess illumination, cost, and energy efficiency. Similarly, our work suggests that the most appropriate use of the visible portion of direct, nondiffuse sunlight from an energy-savings perspective is to displace electric light rather than generate electricity. Early estimates detailed in this paper suggest an anticipated system cost of well under $2.0/Wp and 5-11 {cents}/kWh for displaced and generated electricity in single-story commercial building applications. Based on a number of factors discussed in the paper, including sunlight availability, building use scenarios, time-of-day electric utility rates, cost, and efficacy of the displaced electric lights, the simple payback of this approach in many applications could eventually be well under 5 years.

Light-Light Scattering  

E-Print Network (OSTI)

For a long time, it is believed that the light by light scattering is described properly by the Lagrangian density obtained by Heisenberg and Euler. Here, we present a new calculation which is based on the modern field theory technique. It is found that the light-light scattering is completely different from the old expression. The reason is basically due to the unphysical condition (gauge condition) which was employed by the QED calcualtion of Karplus and Neumann. The correct cross section of light-light scattering at low energy of $(\\frac{\\omega}{m} \\ll 1)$ can be written as $ \\displaystyle{\\frac{d\\sigma}{d\\Omega}=\\frac{1}{(6\\pi)^2}\\frac{\\alpha^4} {(2\\omega)^2}(3+2\\cos^2\\theta +\\cos^4\\theta)}$.

The history of lighting can be viewed as the development of increasingly efficient technologies for creating visible light inside, but not wasted light outside, of that spectral region. A 200-year perspective on that history is shown in the figure above. The left axis indicates luminous efficacy, in units of lumens (a measure of light which factors in the human visual response to various wavelengths) per watt. The right axis indicates the corresponding power-conversion efficiency for a tri-LED tri-color white light source with moderate color rendering (CRI=80) and relatively warm color temperature (CCT=3900K). For such a source, 400lm/W would correspond to 100% power-conversion efficiency.

Action Spectra for Human Skin Cells: Estimates of the Relative Cytotoxicity of the Middle Ultraviolet, Near Ultraviolet, and Violet Regions of Sunlight on  

E-Print Network (OSTI)

Action spectra for the cytotoxic action of electromagnetic radiation in the solar range 280-434 nm have been determined for human fibroblasts and epidermal keratinocytes derived from the same foreskin biopsy. The spectra for the two cell types are close to identical and coincide with our previously published data for a human lymphoblastoid line indicating that the mechanism of inactivation of the three human cell types is similar at any given wavelength. Using published data for ultraviolet transmission of human skin and sample spectral irradiara'data, we have estimated the relative biological effectiveness of the middle ultraviolet (UVB) (290-320 nm), near ultraviolet (UVA) (320-380 nm), and violet (380-434 nm) regions of sunlight for cytotoxicity at the basal layer of the epidermis. We conclude that the UVB component in noon summer sunlight (the most UVB rich spectral conditions tested) may contribute only about 40 % of the total cytotoxic effectiveness of sunlight at 290-

Effect of light intensity on photosynthesis by thermal algae adapted to natural and reduced  

E-Print Network (OSTI)

Thermal algae in alkaline hot springs of Yellowstone National Park (Wyoming) grow as compact mats in which self-shading is extensive, as shown by measurement by autoradiog-raphy of photosynthetic activity of cells at different levels in the mat. The effect of light intensity on photosynthesis of the algal mats was studied using neutral density filters during incubation with lCO Despite the intense sunlight at the altitude of Yellowstone, light inhibition by full sur$ght was observed only occasionally; the rate of photosynthesis fell progressively with decreasing light, although the most efficient use was at 7-14s of full sunlight. Later, the light intensity over portions of the algal mats was reduced to 18 % of full sunlight by installing neutral density glass plates, and changes of chlorophyll content, cell number, and response of photosynthesis to light intensity were determined over the next year. Although the chlorophyll content of the algae at the surface of the mat rose quickly, the chlorophyll content of the mat as a whole rose slowly or not at all; the photosynthetic response of the algal mats to full and reduced sunlight also changed slowly or not at all. Although individual algal cells can adapt rapidly to changes in light, the entire population, because of its existence in compact mats, adapts slowly. At the latitude of Yellowstone there is sufficient light throughout the year to enable algal growth to occur even at temperatures near the upper limit at which blue-green algae can grow; in Iceland, hot spring algae cannot grow during several winter months. Natural ultraviolet radiation neither inhibited nor stimulated photosynthesis.

Improved Light Utilization in Camelina: Center for Enhanced Camelina Oil (CECO)  

SciTech Connect

PETRO Project: The Danforth Center will optimize light utilization in Camelina, a drought-resistant, cold-tolerant oilseed crop. The team is modifying how Camelina collects sunlight, engineering its topmost leaves to be lighter in color so sunlight can more easily reflect onto lower parts of the plant. A more uniform distribution of light would improve the efficiency of photosynthesis. Combined with other strategies to produce more oil in the seed, Camelina would yield more oil per plant. The team is also working to allow Camelina to absorb carbon dioxide (CO2) more efficiently, providing more carbon input for oil production. The goal is to improve light utilization and oil production to the point where Camelina produces enough fuel precursors per acre to compete with other fuels.

Illumination of interior spaces by bended hollow light guides: Application of the theoretical light propagation method  

SciTech Connect

To ensure comfort and healthy conditions in interior spaces the thermal, acoustics and daylight factors of the environment have to be considered in the building design. Due to effective energy performance in buildings the new technology and applications also in daylight engineering are sought such as tubular light guides. These allow the transport of natural light into the building core reducing energy consumption. A lot of installations with various geometrical and optical properties can be applied in real buildings. The simplest set of tubular light guide consists of a transparent cupola, direct tube with high reflected inner surface and a ceiling cover or diffuser redistributing light into the interior. Such vertical tubular guide is often used on flat roofs. When the roof construction is inclined a bend in the light guide system has to be installed. In this case the cupola is set on the sloped roof which collects sunlight and skylight from the seen part of the sky hemisphere as well as that reflected from the ground and opposite facades. In comparison with the vertical tube some additional light losses and distortions of the propagated light have to be expected in bended tubular light guides. Recently the theoretical model of light propagation was already published and its applications are presented in this study solving illuminance distributions on the ceiling cover interface and further illuminance distribution on the working plane in the interior.

Daylighting: Measuring the Performance of Light Shelves and Occupant-Controlled Blinds on a Dimmed Lighting Systems  

E-Print Network (OSTI)

The design of a day lighted space is both an art and a science. The biggest challenge facing the lighting designer is to admit only as much light as necessary and distribute it evenly throughout the space without introducing glare or heat. In warm climates such as Florida, it has become common practice in windowed spaces to specify blinds and glazing with high shading coefficients to control glare and minimize heat gain. However, this practice reduces the effectiveness of lighting systems that dim automatically. Improved systems are needed to capture natural daylight and distribute it uniformly throughout a space while controlling heat gain and glare. One such system is the light shelf. Light shelves shade the space from direct sunlight and reflect this sunlight onto the ceiling for a deeper and more uniform distribution. While this is not a new idea, little unbiased empirical data has been collected, outside the laboratory, that compares the performance (energy savings, uniformity, and level) of an automatic daylighting system. This study measures the effectiveness of light shelves and manually controlled horizontal blinds in an automatic daylighting system. Power consumption and interior work-plane lighting levels were compared in four essentially identical private offices. Two offices were configured with an interior light shelf, one with a white diffuse top surface and the other with a specular surface. The third office had no window treatment and the fourth office had horizontal blinds, which were manually adjusted by the user. All offices had two lamp fluorescent luminaires with dimming ballasts (min. 20%) controlled by a ceiling mounted photosensor. The study showed that daytime savings ranged from 29% to 46%, with the largest savings from the office with the light shelves. The office with horizontal blinds showed the poor savings (32%) and also the poorest light uniformity and level.

New lighting and controls to save 67% at mall  

SciTech Connect

A metal halide lighting system and a Staco control system that dims lighting in response to sunlight should save a Dallas hotel and office mall 67% in electricity costs. The new system replaces quartz lamps in the 160-foot-high atrium. The savings are a combination of state tax credits and lower air conditioning costs, which will pay for the $25,000 project in about 18 months. The metal halide system was chosen over sodium lighting in order to have more attractive color rendition and because it provides about twice as many lumens per watt as the quartz lamps. The Staco system will dim lamps in response to outdoor light and turn lights above a skating rink on and off at prescribed times.

Electrodeless lighting RF power source development. Final report  

SciTech Connect

An efficient, solid state RF power source has been developed on this NICE project for exciting low power electrodeless lamp bulbs. This project takes full advantage of concurrent advances in electrodeless lamp technology. Electrodeless lamp lighting systems utilizing the sulfur based bulb type developed by Fusion Lighting, Inc., is an emerging technology which is based on generating light in a confined plasma created and sustained by RF excitation. The bulb for such a lamp is filled with a particular element and inert gas at low pressure when cold. RF power from the RF source creates a plasma within the bulb which reaches temperatures approaching those of high pressure discharge lamp plasmas. At these temperatures the plasma radiates substantial visible light with a spectrum similar to sunlight.

Plasma lighting, fiber optics, and daylight collectors: Toward the next revolution in high-efficiency illumination  

SciTech Connect

Combining three recently marketed innovations may provide the next revolution in illumination, making many other recent advances eventually obsolete. The first is plasma lighting, pioneered by Fusion Lighting Inc. of Rockville, Maryland, and first commercially applied by Hutchins International Ltd. of Mississauga, Ontario. This microwave-generated light source yields very high-quality light with efficacies at or beyond high intensity discharge (HID) lamps. The source uses no mercury, thus eliminating lamp disposal problems, and has no cathode, thereby providing very long lamp life. Using no phosphors, it also has very short start and re-strike periods, and is dimmable. The second innovation is in the distribution of light. Commercial developments in fiber optics and light guides now provide products that transfer light from a remote point and distribute it like standard light fixtures. Advances in fiber optic communications and applications to decorative lighting have supplied relatively economical systems for mounting and directing light from both electric light sources and the sun. The third advance is a result of efforts to harness daylight. Unlike architectural daylighting that directs sunlight into perimeter areas through glazing, daylight collectors are roof-mounted devices that supply light to interior and underground spaces through hollow columns and open chases. Aided by improvements and cost reductions in sun-tracking (i.e., heliostatic) controls that capture and concentrate sunlight, such collectors offer a source of free light to locations that might otherwise never receive it. When combined together, these three options could offer a centralized building lighting system that pipes lumens to distribution devices replacing many existing lamps and fixtures.

Eisenbeis, Supt. of Conservation NORTHERN LIGHTS To a person seeing the Aurora Borealis or "northern lights" for the first time, it is an uncanny awe-inspiring spectacle. Sometimes it begins as a glow of red on the northern horizon, ominously suggesting a great fire, gradually changing to a curtain of violet-white, or greenish-yellow light extending from east to west. Some times this may be transformed to appear as fold upon fold of luminous draperies that march majestically across the sky; sometimes as a vast multitude of gigantic flaming swords furiously slashing at the heavens; sometimes as a flowing crown with long undulating colored streamers fanning downward and outward.

Shipboard lighting: A.D. 400-1900  

E-Print Network (OSTI)

From A.D. 400-1900, illumination was gained by simply lighting a fibrous wick soaked in a burnable fuel. Yet, this basic technology played an integral part in the every day functioning of ships. Vessels which either sailed through the night or conducted evening meals and prayers by lamp or candle light, typically traveled longer distances in fewer days than those which limited all activities to day-light hours. After 1500, ships became increasingly larger which also elevated the amount of illumination needed for work below decks even when the sun was shining. An understanding of how illumination was used on ships would give a clearer picture of how ship-board life was conducted. This thesis will, therefore, bring relevant material about lighting on ships together in a comprehensive analysis. Three main areas of interest will be examined using information from the archaeological and historical records: 1) technological developments and lighting trends through out the period, 2) locations and types of the implements used, and 3) how sun-light may have been directed into the hold to reduce the risk of fire. With these details, another portion of ship-board life will come, as they say, to light.

Theoretical solution for light transmission of a bended hollow light guide  

SciTech Connect

Hollow light guides with very high reflective inner surfaces are novel daylight systems that collect sunlight and skylight available on the roof of buildings transporting it into deep or windowless interiors in building cores. Thus the better utilization of daylight can result in energy savings and wellbeing in these enclosed indoor spaces. An analytical complex solution of a straight tube system was solved in the HOLIGILM method with a user-friendly tool available on the http://www.holigilm.info. An even more difficult light flow transport is to be determined in bended tubes usually placed on sloped roofs where a bend is necessary to adjust the vertical pass through the ceilings. This paper presents the theoretical derivation of the model with its graphical representation and coordinate system respecting backward ray-tracing bend distortions. To imagine the resulting illuminance on the horizontal plane element in the interior, the virtual ray (i.e. luminance in an elementary solid angle) has to pass the ceiling diffuser interface, the inner mirror like tube with a bend, through a roof cupola attachment to the element of the sky and sun light source. Due to this complexity and the lengthy derivation and explanations more practical applications will be published later in a separate contribution. (author)

Atomistic study of energy funneling in the light-harvesting complex of green sulfur bacteria  

E-Print Network (OSTI)

Phototrophic organisms such as plants, photosynthetic bacteria and algae use microscopic complexes of pigment molecules to absorb sunlight. Within the light-harvesting complexes, which frequently have multiple functional and structural subunits, the energy is transferred in the form of molecular excitations with very high efficiency. Green sulfur bacteria are considered to be amongst the most efficient light-harvesting organisms. Despite multiple experimental and theoretical studies of these bacteria the physical origin of the efficient and robust energy transfer in their light-harvesting complexes is not well understood. To study excitation dynamics at the systems level we introduce an atomistic model that mimic a complete light-harvesting apparatus of green sulfur bacteria. The model contains about 4000 pigment molecules and comprises a double wall roll for the chlorosome, a baseplate and six Fenna-Matthews-Olson trimer complexes. We show that the fast relaxation within functional subunits combined with the...

Practical method for including material scattering effects in determining the amount of intercepted sunlight in solar concentrators  

DOE Green Energy (OSTI)

In imaging solar concentrators, the amount of solar radiation incident on a receiver surface depends upon both the overall concentrator shape and the angular distribution of light rays (sunshape) that reach the receiver. Sunshape broadening effects, which include the specular reflectance or transmittance properties of mirrors or glazings, image degradation caused by surface slope errors, and tracking errors are combined into an effective error cone. Broadened sunshapes for a variety of effective error-cone distributions are calculated and presented in graphical form. It is found that when the root-mean-square (RMS) width of the effective error cone is approximately 2 to 3 times the RMS width of the incident sunshape, the broadened sunshape can be adequately described by a circular normal distribution.

Cooling energy savings potential of light-colored roofs for residential and commercial buildings in 11 US metropolitan areas  

SciTech Connect

Light-colored roofs reflect more sunlight than dark roofs, thus they keep buildings cooler and reduce air-conditioning demand. Typical roofs in the United States are dark, which creates a potential for savings energy and money by changing to reflective roofs. In this report, the authors make quantitative estimates of the impact of roof color by simulating prototypical buildings with light- and dark-colored roofs and calculating savings by taking the differences in annual cooling and heating energy use, and peak electricity demand. Monetary savings are calculated using local utility rates. Savings are estimated for 11 U.S. Metropolitan Statistical Areas (MSAs) in a variety of climates.

First Light  

E-Print Network (OSTI)

The first dwarf galaxies, which constitute the building blocks of the collapsed objects we find today in the Universe, had formed hundreds of millions of years after the big bang. This pedagogical review describes the early growth of their small-amplitude seed fluctuations from the epoch of inflation through dark matter decoupling and matter-radiation equality, to the final collapse and fragmentation of the dark matter on all mass scales above \\~10^{-4} solar masses. The condensation of baryons into halos in the mass range of ~10^5-10^{10} solar masses led to the formation of the first stars and the re-ionization of the cold hydrogen gas, left over from the big bang. The production of heavy elements by the first stars started the metal enrichment process that eventually led to the formation of rocky planets and life. A wide variety of instruments currently under design [including large-aperture infrared telescopes on the ground or in space (JWST), and low-frequency arrays for the detection of redshifted 21cm radiation], will establish better understanding of the first sources of light during an epoch in cosmic history that was largely unexplored so far. Numerical simulations of reionization are computationally challenging, as they require radiative transfer across large cosmological volumes as well as sufficently high resolution to identify the sources of the ionizing radiation. The technological challenges for observations and the computational challenges for numerical simulations, will motivate intense work in this field over the coming decade.

New Light Sources for Tomorrow's Lighting Designs  

E-Print Network (OSTI)

The lighting industry is driven to provide light sources and lighting systems that, when properly applied, will produce a suitable luminous environment in which to perform a specified task. Tasks may include everything from office work, manufacturing and inspection to viewing priceless art objects, selecting the right chair for your living room, and deciding which produce item to select for tonight's dinner. While energy efficiency is a major consideration in any new lighting system design, the sacrifice of lighting quality may cost more in terms of lost productivity and user dissatisfaction than can ever be saved on that monthly energy bill. During the past several years, many new light sources have been developed and introduced. These product introductions have not been limited to anyone lamp type, but instead may be found in filament, fluorescent and high intensity discharge lamp families. Manufacturers of light sources have two basic goals for new product development. These goals are high efficiency lighting and improved color rendering properties. High efficiency lighting may take the form of either increasing lamp efficiency (lumens of light delivered per watt of power consumed) or decreasing lamp size, thus making a more easily controlled light source that places light where it is needed. The manufacturer's second goal is to produce lamps that render colors accurately while maintaining high efficiency. This paper will discuss new introductions in light sources and lighting systems and how they may impact the design of luminous environments of the future.

Light incoherence theory revisited by Heisenberg time-energy uncertainty challenges solar cell optimization  

E-Print Network (OSTI)

Optimization of the efficiency of solar cells is a major challenge for renewable energies. Using a rigorous theoretical approach, we show that the photocurrent generated in a solar cell depends strongly on the degree of coherence of the incident light. In accordance with Heisenberg uncertainty time-energy, incoherent light at photons of carrier energy lower than the active material bandgap can be absorbed whereas coherent light at the same carrier energy cannot. We identify cases where incoherence does enhance efficiency. This result has a dramatical impact on the way solar cells must be optimized regarding sunlight. As an illustration, surface-corrugated GaAs and c-Si thin-film solar cells are considered.

Abstract In this paper we introduce geometrydependent lighting that allows lighting parameters to be defined independently and possibly discrepantly over an object or scene based on the local geometry. We present and discuss Light Collages, a lighting design system with geometry-dependent lights for effective feature-enhanced visualization. Our algorithm segments the objects into local surface patches and places lights that are locally consistent but globally discrepant to enhance the perception of shape. We use spherical harmonics for efficiently storing and computing light placement and assignment. We also outline a method to find the minimal number of light sources sufficient to illuminate an object well with our globally discrepant lighting approach. Index Terms Lighting design, scientific illustration, discrepant lighting, light placement, silhouette enhancement, proximity shadows, spherical harmonics I.

Composite Lighting Simulations with Lighting Networks  

E-Print Network (OSTI)

A whole variety of different techniques for simulating global illumination in virtual environments have been developed over recent years. Each technique, including Radiosity, Monte-Carlo ray- or photon tracing, and directional-dependent Radiance computations, is best suited for simulating only some special case environments. None of these techniques is currently able to efficiently simulate all important lighting effects in non-trivial scenes. In this paper, we describe a new approach for efficiently combining different global illumination algorithms to yield a composite lighting simulation: Lighting Networks. Lighting Networks can exploit the advantages of each algorithm and can combine them in such a way as to simulate lighting effects that could only be computed at great costs by any single algorithm. Furthermore, this approach allows a user to configure the Lighting Network to compute only specific lighting effects that are important for a given task, while avoiding a costly simulation of the full global illumination in a scene. We show how the light paths computed by a Lighting Network can be described using regular expressions. This mapping allows us to analyze the composite lighting simulation and ensure completeness and redundant-free computations. Several examples demonstrate the advantages and unique lighting effects that can be obtained using this technique. 1

Energy and lighting decisions  

SciTech Connect

This report reviews the fundamental principles of lighting and uses them to evaluate energy-conserving lighting equipment and techniques. The selection of the proper lighting components and systems is complex, requiring a knowledge of the characteristics of light sources and their interactions with the auxiliary equipment and the environment. Furthermore, there are subjective aspects of lighting that are difficult to quantify. We address the simplistic way in which lighting is commonly approached, then present an argument as to the critical nature of the lighting decision. In the final sections we discuss and evaluate lighting equipment in terms of its applications and characteristics. Familiarity with the fundamental characteristics of the elements of lighting equipment will also permit more judicious appraisal and use of lighting concepts that may be introduced in the future. 6 figs., 9 tabs.

The effects of concentrated ultraviolet light on high-efficiency silicon solar cells  

DOE Green Energy (OSTI)

The importance of stability in the performance of solar cells is clearly recognized as fundamental. Some of the highest efficiency silicon solar cells demonstrated to date, such as the Point Contact solar cell and the Passivated Emitter solar cell, rely upon the passivation of cell surfaces in order to minimize recombination, which reduces cell power output. Recently, it has been shown that exposure to ultraviolet (UV) light of wavelengths present in the terrestrial solar spectrum can damage a passivating silicon-oxide interface and increase recombination. In this study, we compared the performance of Point Contact and Passivated Emitter solar cells after exposure to UV light. We also examined the effect of UV exposure on oxide-passivated silicon wafers. We found that current Passivated Emitter designs are stable at both one-sun and under concentrated sunlight. The evolution of Point Contact concentrator cell performance shows a clear trend towards more stable cells. 15 refs., 18 figs.

Natural lighting and skylights  

E-Print Network (OSTI)

There are many physiological and psychological factors which enter into the proper design of space for human occupancy. One of these elements is light. Both natural light and manufactured light are basic tools with which any designer must work. However, they are only two of the many, many elements which must be considered; and they, therefore, must be considered, always, in relation to the other elements. The achievement of good lighting depends on a reasonable understanding of three primary factors: one, the visual response to lighting; two, the availability and types of lighting; and three, methods for controlling light. This thesis is intended to supply enough information to provide a working knowledge of each of these facets. The human visual response is discussed in "Goals For Good Lighting." The availability and types of lighting are dealt with in the section on available light. The remainder of the thesis concerns methods for controlling light. The use of scale models for studying the natural lighting characteristics of buildings due to the building geometry, the fenestration details and the interior reflectance has been well established as pointed out in the earlier part of this thesis. With the completion of the work outlined herein, the feasibility of using scale models for studying skylights is also an established fact. The method of analysis by models can be a valuable tool to any designer who is concerned about day-lighting.

Developing a dynamic envelope/lighting control system with field measurements  

SciTech Connect

The feasibility of an intelligent venetian blind/lighting control system was tested in a 1:3 scale model outdoors under variable sun and sky conditions. The control algorithm, block direct sun and meet the design workplane illuminance level, was implemented using commercially available and custom designed blind and lighting systems hardware. While blocking direct sunlight, the blinds were properly controlled to maintain the design workplane illuminance within a tolerance of -10%, +25% when there was sufficient daylight. When daylight levels alone were inadequate, the electric lighting control system maintained the design workplane illuminance. The electric lighting could be turned off if a user-specified time period at minimum power was exceeded. Lighting energy savings of 51-71% (southwest) and 37-75% (south) was attained for the period from 8:00 to 17:00 on clear sunny days, compared to a fixed, partially closed blind with the same lighting system. Practical details for implementation and commissioning are discussed. The impact of control variations, such as profile angle, time step interval, and control area, on energy demand is investigated.

Inverse Lighting for Photography  

E-Print Network (OSTI)

We introduce a technique for improving photographs using inverse lighting, a new process based on algorithms developed in computer graphics for computing the reflection of light in 3D space. From a photograph and a 3D surface model for the object pictured, inverse lighting estimates the directional distribution of the incident light. We then use this information to process the photograph digitally to alter the lighting on the object. Inverse lighting is a specific example of the general idea of inverse rendering. This refers to the practice of using the methods of computer graphics, which normally are used to render images from scene information, to infer scene information from images. Our system uses physically based rendering technology to construct a linear least squares system that we solve to find the lighting. As an application, the results are then used to simulate a change in the incident light in the photograph. An implementation is described that uses 3D models from a laser...

Automatic lighting controls demonstration  

SciTech Connect

The purpose of this work was to demonstrate, in a real building situation, the energy and peak demand reduction capabilities of an electronically ballasted lighting control system that can utilize all types of control strategies to efficiently manage lighting. The project has demonstrated that a state-of-the-art electronically ballasted dimmable lighting system can reduce energy and lighting demand by as least 50% using various combinations of control strategies. By reducing light levels over circulation areas (tuning) and reducing after hours light levels to accommodate the less stringent lighting demands of the cleaning crew (scheduling), lighting energy consumption on weekdays was reduced an average of 54% relative to the initial condition. 10 refs., 14 figs., 3 tabs.

PFP Emergency Lighting Study  

SciTech Connect

NFPA 101, section 5-9 mandates that, where required by building classification, all designated emergency egress routes be provided with adequate emergency lighting in the event of a normal lighting outage. Emergency lighting is to be arranged so that egress routes are illuminated to an average of 1.0 footcandle with a minimum at any point of 0.1 footcandle, as measured at floor level. These levels are permitted to drop to 60% of their original value over the required 90 minute emergency lighting duration after a power outage. The Plutonium Finishing Plant (PFP) has two designations for battery powered egress lights ''Emergency Lights'' are those battery powered lights required by NFPA 101 to provide lighting along officially designated egress routes in those buildings meeting the correct occupancy requirements. Emergency Lights are maintained on a monthly basis by procedure ZSR-12N-001. ''Backup Lights'' are battery powered lights not required by NFPA, but installed in areas where additional light may be needed. The Backup Light locations were identified by PFP Safety and Engineering based on several factors. (1) General occupancy and type of work in the area. Areas occupied briefly during a shiftly surveillance do not require backup lighting while a room occupied fairly frequently or for significant lengths of time will need one or two Backup lights to provide general illumination of the egress points. (2) Complexity of the egress routes. Office spaces with a standard hallway/room configuration will not require Backup Lights while a large room with several subdivisions or irregularly placed rooms, doors, and equipment will require Backup Lights to make egress safer. (3) Reasonable balance between the safety benefits of additional lighting and the man-hours/exposure required for periodic light maintenance. In some plant areas such as building 236-Z, the additional maintenance time and risk of contamination do not warrant having Backup Lights installed in all rooms. Sufficient light for egress is provided by existing lights located in the hallways.

Photonic crystal light source  

DOE Patents (OSTI)

A light source is provided by a photonic crystal having an enhanced photonic density-of-states over a band of frequencies and wherein at least one of the dielectric materials of the photonic crystal has a complex dielectric constant, thereby producing enhanced light emission at the band of frequencies when the photonic crystal is heated. The dielectric material can be a metal, such as tungsten. The spectral properties of the light source can be easily tuned by modification of the photonic crystal structure and materials. The photonic crystal light source can be heated electrically or other heating means. The light source can further include additional photonic crystals that exhibit enhanced light emission at a different band of frequencies to provide for color mixing. The photonic crystal light source may have applications in optical telecommunications, information displays, energy conversion, sensors, and other optical applications.

Advances in Lighting  

E-Print Network (OSTI)

Increasing electricity costs have made a significant impact on lighting. The Illuminating Engineering society (I.E.S.) and the lighting industry are producing new standards, procedures and products to make lighting more appropriate and energy efficient. This paper will describe the factors which affect the performance of lighting systems, introduce the new I.E.S. procedures for selecting illuminance values and lighting power limits, and illustrate some of the recent developments in the lighting industry. The importance of efficient lighting may be measured by the potential reduction in the electrical demand, and energy consumed. Since it also represents a visible use (or misuse) of energy, it may also reflect on other aspects of a company's energy management program.

Evolution in lighting  

SciTech Connect

Lights consume 20-25% of the nation's electricity, establishing strong incentives to develop more efficient lighting strategies. Attention is turning to where, when, and how we light our environment, and the potential savings add up to half the lighting load nationwide. Some types of lamp are more efficient than others, but characteristics other than energy consumption may dictate where they can be used. Current lighting strategies consider task requirements, light quality, and the potential for daylighting. Energy management systems that control the timing and intensity of light and new types of energy-efficient bulbs and fixtures are increasingly attractive to consumers. The effort will require continued research and the awareness of decision makers. 4 references, 8 figures.

Light truck forecasts  

SciTech Connect

The recent dramatic increase in the number of light trucks (109% between 1963 and 1974) has prompted concern about the energy consequences of the growing popularity of the light truck. An estimate of the future number of light trucks is considered to be a reasonable first step in assessing the energy impact of these vehicles. The monograph contains forecasts based on two models and six scenarios. The coefficients for the models have been derived by ordinary least squares regression of national level time series data. The first model is a two stage model. The first stage estimates the number of light trucks and cars (together), and the second stage applies a share's submodel to determine the number of light trucks. The second model is a simultaneous equation model. The two models track one another remarkably well, within about 2%. The scenarios were chosen to be consistent with those used in the Lindsey-Kaufman study Projection of Light Truck Population to Year 2025. Except in the case of the most dismal economic scenario, the number of light trucks is expected to increase from the 1974 level of 0.09 light truck per person to about 0.12 light truck per person in 1995.

Light intensity compressor  

DOE Patents (OSTI)

In a system for recording images having vastly differing light intensities over the face of the image, a light intensity compressor is provided that utilizes the properties of twisted nematic liquid crystals to compress the image intensity. A photoconductor or photodiode material that is responsive to the wavelength of radiation being recorded is placed adjacent a layer of twisted nematic liquid crystal material. An electric potential applied to a pair of electrodes that are disposed outside of the liquid crystal/photoconductor arrangement to provide an electric field in the vicinity of the liquid crystal material. The electrodes are substantially transparent to the form of radiation being recorded. A pair of crossed polarizers are provided on opposite sides of the liquid crystal. The front polarizer linearly polarizes the light, while the back polarizer cooperates with the front polarizer and the liquid crystal material to compress the intensity of a viewed scene. Light incident upon the intensity compressor activates the photoconductor in proportion to the intensity of the light, thereby varying the field applied to the liquid crystal. The increased field causes the liquid crystal to have less of a twisting effect on the incident linearly polarized light, which will cause an increased percentage of the light to be absorbed by the back polarizer. The intensity of an image may be compressed by forming an image on the light intensity compressor.

Exploring Lighting Spaces  

E-Print Network (OSTI)

We present a simple system for interactively specifying lighting parameters, including position, for high-quality image synthesis. Unlikeinverse approaches to the lighting-design problem, we do not require the user to indicate a priori the desired illuminative characteristics of an image. In our approach the computer proposes, culls, and organizes a set of candidate lights automatically, using an elementary measure of image similarityasthe basis for both culling and organization. The user then browses the set of candidate-light images, selects which lights to include, and combines them as desired. This work is a particular instance of a general strategy --- sampling a design space broadly and intelligently and organizing the results for rapid browsing by the user --- that may be applicable to many other design problems in computer graphics.

Hybrid lighting: Illuminating our future  

SciTech Connect

Hybrid lighting is a combination of natural and artificial illumination to be used indoors for all lighting needs. Ideally, hybrid lighting is effectively indistinguishable from standard artificial lighting except in quality and cost, where it will likely be an improvement. Hybrid lighting systems are produced by a combination of four technologies: collecting natural light, generating artificial light, transporting and distributing light to where it is needed, and controlling the amounts of both natural and artificial light continuously during usage. Lighting demands a large fraction of our energy needs. If we can control or decrease this demand, we are able to accommodate societal growth without energy demand growth.

Light and Bread Mold Light and Bread Mold Name: CHASE Location: N/A Country: N/A Date: N/A Question: HOW CAN I EFICTIVELY TEST THE EFFECTS OF LIGHT ON BREAD MOLD? Replies: Hello Chase, In order to test the effects of light on bread mould you need to set up an experiment. There are two things you need to have in your experiment to make it a good experiment: 1. A 'control'. 2. Replicates 1. The 'control' Obviously in order to test the effects of light on bread mold you will need to actually shine some light on some bread mold and see what happens. This is your 'treatment'. However, it is vitally important that you know what would have happened without the treatment (in this case added light). Let's pretend that you do a test a you find that the bread mold under the light actually dies. How do you know if your bread mold died because light was added or because at that time of year all bread mold would die naturally or because by adding light you caused the temperature to rise and that killed the bread mold? The answer is that you do not know unless you have taken the trouble to find out with anouther test called the 'control'. The 'control' is a piece of bread mold, identical to the 'treatment' bread mold, which is placed in identical conditions to the 'treatment' piece of bread mold except that light is removed. Your 'control' piece of bread mold will need to be (to the best of your abillity) at the same temperature, in the same area, at similar humidity, etc. Part of the skill of designing a scientific experiment is being able think of all the possible things which might be affecting the bread mold and keeping them the same in both the 'treatment' and the 'control' (except, of course, for the presence of light) so that when you find a difference between the 'treatment' and the 'control' you are sure that it is the result of the light rather than something else.

Induction Lighting: An Old Lighting Technology Made New Again Induction Lighting: An Old Lighting Technology Made New Again Induction Lighting: An Old Lighting Technology Made New Again July 27, 2009 - 5:00am Addthis John Lippert Induction lighting is one of the best kept secrets in energy-efficient lighting. Simply stated, induction lighting is essentially a fluorescent light without electrodes or filaments, the items that frequently cause other bulbs to burn out quickly. Thus, many induction lighting units have an extremely long life of up to 100,000 hours. To put this in perspective, an induction lighting system lasting 100,000 hours will last more than 11 years in continuous 24/7 operation, and 25 years if operated 10 hours a day. The technology, however, is far from new. Nikola Tesla demonstrated induction lighting in the late 1890s around the same time that his rival,

Atomistic study of energy funneling in the light-harvesting complex of green sulfur bacteria  

E-Print Network (OSTI)

Phototrophic organisms such as plants, photosynthetic bacteria and algae use microscopic complexes of pigment molecules to absorb sunlight. Within the light-harvesting complexes, which frequently have multiple functional and structural subunits, the energy is transferred in the form of molecular excitations with very high efficiency. Green sulfur bacteria are considered to be amongst the most efficient light-harvesting organisms. Despite multiple experimental and theoretical studies of these bacteria the physical origin of the efficient and robust energy transfer in their light-harvesting complexes is not well understood. To study excitation dynamics at the systems level we introduce an atomistic model that mimic a complete light-harvesting apparatus of green sulfur bacteria. The model contains about 4000 pigment molecules and comprises a double wall roll for the chlorosome, a baseplate and six Fenna-Matthews-Olson trimer complexes. We show that the fast relaxation within functional subunits combined with the transfer between collective excited states of pigments can result in robust energy funneling that is weakly dependent on the initial excitation conditions and temperature changes. Moreover, the same mechanism describes the coexistence of multiple timescales of excitation dynamics frequently observed in ultrafast optical experiments. While our findings support the hypothesis of supertransfer, the model reveals energy transport through multiple channels on different length scales.

Long range excitonic transport in a biomimetic system inspired by the bacterial light-harvesting apparatus  

Science Conference Proceedings (OSTI)

Photosynthesis, the process by which energy from sunlight drives cellular metabolism, relies on a unique organization of light-harvesting and reaction center complexes. Recently, the organization of light-harvesting LH2 complexes and dimeric reaction center-light-harvesting I-PufX core complexes in membranes of purple non-sulfur bacteria was revealed by atomic force microscopy [S. Bahatyrova et al., Nature (London) 430, 1058 (2004)]. Here, we discuss optimal exciton transfer in a biomimetic system closely modeled on the structure of LH2 and its organization within the membrane using a Markovian quantum model with dissipation and trapping added phenomenologically. In a deliberate manner, we neglect the high level detail of the bacterial light-harvesting complex and its interaction with the phonon bath in order to elucidate a set of design principles that may be incorporated in artificial pigment-scaffold constructs in a supramolecular assembly. We show that our scheme reproduces many of the most salient features found in their natural counterpart and may be largely explained by simple electrostatic considerations. Most importantly, we show that quantum effects act primarily to enforce robustness with respect to spatial and spectral disorder between and within complexes. The implications of such an arrangement are discussed in the context of biomimetic photosynthetic analogs capable of transferring energy efficiently across tens to hundreds of nanometers.

National Synchrotron Light Source 2010 Activity Report  

Science Conference Proceedings (OSTI)

This is a very exciting period for photon sciences at Brookhaven National Laboratory. It is also a time of unprecedented growth for the Photon Sciences Directorate, which operates the National Synchrotron Light Source (NSLS) and is constructing NSLS-II, both funded by the Department of Energy's Office of Science. Reflecting the quick pace of our activities, we chose the theme 'Discovery at Light Speed' for the directorate's 2010 annual report, a fiscal year bookended by October 2009 and September 2010. The year began with the news that NSLS users Venki Ramakrishnan of Cambridge University (also a former employee in Brookhaven's biology department) and Thomas A. Steitz of Yale University were sharing the 2009 Nobel Prize in Chemistry with Ada E. Yonath of the Weizmann Institute of Science. Every research project has the potential for accolades. In 2010, NSLS users and staff published close to 900 papers, with about 170 appearing in premiere journals. Those are impressive stats for a facility nearly three decades old, testament to the highly dedicated team keeping NSLS at peak performance and the high quality of its user community. Our NSLS users come from a worldwide community of scientists using photons, or light, to carry out research in energy and environmental sciences, physics, materials science, chemistry, biology and medicine. All are looking forward to the new capabilities enabled by NSLS-II, which will offer unprecedented resolution at the nanoscale. The new facility will produce x-rays more than 10,000 times brighter than the current NSLS and host a suite of sophisticated instruments for cutting-edge science. Some of the scientific discoveries we anticipate at NSLS-II will lead to major advances in alternative energy technologies, such as hydrogen and solar. These discoveries could pave the way to: (1) catalysts that split water with sunlight for hydrogen production; (2) materials that can reversibly store large quantities of electricity or hydrogen; (3) high-temperature superconducting materials that carry electricity with no loss for efficient power transmission lines; and (4) materials for solid-state lighting with half of the present power consumption. Excitement about NSLS-II is evident in many ways, most notably the extraordinary response we had to the 2010 call for beamline development proposals for the anticipated 60 or more beamlines that NSLS-II will ultimately host. A total of 54 proposals were submitted and, after extensive review, 34 were approved. Funding from both the Department of Energy and the National Institutes of Health has already been secured to support the design and construction of a number of these beamlines. FY11 is a challenging and exciting year for the NSLS-II Project as we reach the peak of our construction activity. We remain on track to complete the project by March 2014, a full 15 months ahead of schedule and with even more capabilities than originally planned. The Photon Sciences Directorate is well on its way to fulfilling our vision of being a provider of choice for world-class photon sciences and facilities.

A reflectance pulse oximeter that determines oxygen saturation of hemoglobin using two sources of electromagnetic radiation in the green optical region, which provides the maximum reflectance pulsation spectrum. The use of green light allows placement of an oximetry probe at central body sites (e.g., wrist, thigh, abdomen, forehead, scalp, and back). Preferably, the two green light sources alternately emit light at 560 nm and 577 nm, respectively, which gives the biggest difference in hemoglobin extinction coefficients between deoxyhemoglobin, RHb, and oxyhemoglobin, HbO.sub.2.

AUTOMATIC LIGHT CONTROL  

DOE Patents (OSTI)

A control system for a projection kinescope used in a facsimile scanning system and, in particular, meams for maintaining substantially constant the light emanating from the flying spot on the face of the kinescope are described. In general, the invention provides a feeler member disposed in such a position with respect to a projecting lens as to intercept a portion of the light striking the lens. Suitable circuitry in conjunction with a photomultiplier tube provides a signal proportional to the light intensity of the flying spot. The grid bias on the kinescope is controlled by this signal to maintain the intensity of the spot substantially constant.

Entangled states of light  

E-Print Network (OSTI)

These notes are more or less a faithful representation of my talk at the Workshop on ``Quantum Coding and Quantum Computing'' held at the University of Virginia. As such it is an introduction for non-physicists to the topics of the quantum theory of light and entangled states of light. In particular, I discuss the photon concept and what is really entangled in an entangled state of light (it is not the photons). Moreover, I discuss an example that highlights the peculiar behavior of entanglement in an infinite-dimensional Hilbert space.

Light Vector Mesons  

E-Print Network (OSTI)

This article reviews the current status of experimental results obtained in the measurement of light vector mesons produced in proton-proton and heavy ion collisions at different energies. The review is focused on two phenomena related to the light vector mesons; the modification of the spectral shape in search of Chiral symmetry restoration and suppression of the meson production in heavy ion collisions. The experimental results show that the spectral shape of light vector mesons are modified compared to the parameters measured in vacuum. The nature and the magnitude of the modification depends on the energy density of the media in which they are produced. The suppression patterns of light vector mesons are different from the measurements of other mesons and baryons. The mechanisms responsible for the suppression of the mesons are not yet understood. Systematic comparison of existing experimental results points to the missing data which may help to resolve the problem.

Practical image based lighting  

E-Print Network (OSTI)

In this thesis, we present a user-friendly and practical method for seamless integration of computer-generated images (CG) with real photographs and video. In general such seamless integration is extremely hard and requires recovery of real world information to simulate the same environment for both CG and real objects. This real world information includes camera positions and parameters, and shapes, material properties, and motion of real objects. Among these one of the most important real world information is lighting. Image based lighting that is developed to recover illumination information of the real world from photographs has recently been popular in computer graphics. In this thesis we present a practical image based lighting method. Our method is based on a simple and easily constructible device: a square plate with a cylindrical stick. We have developed a user-guided system to approximately recover illumination information (i.e. orientations, colors, and intensities of light sources) from a photograph of this device. Our approach also helps to recover surface colors of real objects based on reconstructed lighting information. In addition, we will address our observation on shadows with multi-color lights in a compositing aspect and will present a solution to handle the addressed issue.

Light pipe - design for efficiency  

Science Conference Proceedings (OSTI)

The high cost and availability of materials which are clear enough to transmit light without absorption has limited the idea of piping large-scale quantities of light. The light pipe uses the principle of Total Internal Reflection, with the light guided by very accurate prisms. The transmission of light directed into the end of a Light Pipe at an angle of less than 27.6 degrees is theoretically 100% efficient. The author describes its uses and advantages for lighting offices, cold storage areas, difficult access and hazardous areas, and for solar lighting. Future directions will be to improve the economics and accuracy of the technology. 4 references, 2 figures.

Light Field Appearance Manifolds  

E-Print Network (OSTI)

Abstract. Statistical shape and texture appearance models are powerful image representations, but previously had been restricted to 2D or 3D shapes with smooth surfaces and lambertian reflectance. In this paper we present a novel 3D appearance model using image-based rendering techniques, which can represent complex lighting conditions, structures, and surfaces. We construct a light field manifold capturing the multi-view appearance of an object class and extend the direct search algorithm of Cootes and Taylor to match new light fields or 2D images of an object to a point on this manifold. When matching to a 2D image the reconstructed light field can be used to render unseen views of the object. Our technique differs from previous view-based active appearance models in that model coefficients between views are explicitly linked, and that we do not model any pose variation within the shape model at a single view. It overcomes the limitations of polygonal based appearance models and uses light fields that are acquired in real-time. 1

The radiant energy in the visible region of the spectrum of the lighting subsystems can be adjusted relative to each other so that the total scotopic illumination of the combined system and the total photopic illumination of the combined system can be varied independently. The dilation or contraction of the pupil of an eye is controlled by the level of scotopic illumination and because the scotopic and photopic illumination can be separately controlled, the system allows the pupil size to be varied independently of the level of photopic illumination. Hence, the vision process can be improved for a given level of photopic illumination. 5 figs.

The light cone method provides a convenient non-perturbative tool to study the heavy-to-light form factors. We construct a light cone quark model utilizing the soft collinear effective theory. In the leading order of effective theory, the ten $B$ to light physical form factors are reduced to three universal form factors which can be calculated as overlaps of hadron light front wave functions in the light cone quark model. The numerical results show that the leading contribution is close to the results from other approaches. The $q^2$ dependence of the heavy-to-light form factors are also presented.

Radioluminescent lighting technology  

SciTech Connect

The glow-in-the-dark stereotype that characterizes the popular image of nuclear materials is not accidental. When the French scientist, Henri Becquerel, first discovered radioactivity in 1896, he was interested in luminescence. Radioluminescence, the production of light from a mixture of energetic and passive materials, is probably the oldest practical application of the unstable nucleus. Tritium-based radioluminescent lighting, in spite of the biologically favorable character of the gaseous tritium isotope, was included in the general tightening of environmental and safety regulations. Tritium light manufacturers would have to meet two fundamental conditions: (1) The benefit clearly outweighed the risk, to the extent that even the perceived risk of a skeptical public would be overcome. (2) The need was significant enough that the customer/user would be willing and able to afford the cost of regulation that was imposed both in the manufacture, use and eventual disposal of nuclear materials. In 1981, researchers at Oak Ridge National Laboratory were investigating larger radioluminescent applications using byproduct nuclear material such as krypton-85, as well as tritium. By 1982, it appeared that large source, (100 Curies or more) tritium gas tube, lights might be useful for marking runways and drop zones for military operations and perhaps even special civilian aviation applications. The successful development of this idea depended on making the light bright enough and demonstrating that large gas tube sources could be used and maintained safely in the environment. This successful DOE program is now in the process of being completed and closed-out. Working closely with the tritium light industry, State governments and other Federal agencies, the basic program goals have been achieved. This is a detailed report of what they have learned, proven, and discovered. 91 refs., 29 figs., 5 tabs. (JF)

Fiberoptic home lighting  

Science Conference Proceedings (OSTI)

Initial effort on this grant project was to construct a model that would demonstrate the feasibility of various lighting theories. Testing of suitable materials for utilization as fibreoptic components was the second priority. The material chosen for the project was 5/8 inch diameter plexiglas rod. The next step involved determining the limitations and other properties of the plexiglas rod. The final factor in developing a useable system involved testing different types and colors of light and their ability to be transmitted by the optic fibre. The culmination of the research and testing resulted in the demonstration projects.

Good lighting with energy conservation  

SciTech Connect

The publicity and economic impact of the oil embargo of 1973-74 has frequently caused over-reactive, indiscriminate reductions in lighting without eliminating many of the truly energy-wasteful aspects of lighting system usage. With current technology and a clear knowledge of the lighting requirements significant contributions to energy conservation can be achieved without unnecessarily sacrificing the benefits of good lighting.

Windows and lighting program  

SciTech Connect

More than 30% of all energy use in buildings is attributable to two sources: windows and lighting. Together they account for annual consumer energy expenditures of more than $50 billion. Each affects not only energy use by other major building systems, but also comfort and productivity -- factors that influence building economics far more than does direct energy consumption alone. Windows play a unique role in the building envelope, physically separating the conditioned space from the world outside without sacrificing vital visual contact. Throughout the indoor environment, lighting systems facilitate a variety of tasks associated with a wide range of visual requirements while defining the luminous qualities of the indoor environment. Windows and lighting are thus essential components of any comprehensive building science program. Despite important achievements in reducing building energy consumption over the past decade, significant additional savings are still possible. These will come from two complementary strategies: (1) improve building designs so that they effectively apply existing technologies and extend the market penetration of these technologies; and (2) develop advanced technologies that increase the savings potential of each application. Both the Windows and Daylighting Group and the Lighting System Research Group have made substantial contributions in each of these areas, and continue to do so through the ongoing research summarized here. 23 refs., 16 figs.

Technology reviews: Lighting systems  

SciTech Connect

We present a representative review of existing, emerging, and future technology options in each of five hardware and systems areas in envelope and lighting technologies: lighting systems, glazing systems, shading systems, daylighting optical systems, and dynamic curtain wall systems. The term technology is used here to describe any design choice for energy efficiency, ranging from individual components to more complex systems to general design strategies. The purpose of this task is to characterize lighting system in the state of the art in envelope and lighting technologies in order to identify those with promise for advanced integrated systems, with an emphasis on California commercial buildings. For each technology category, the following activities have been attempted to the extent possible: Identify key performance characteristics and criteria for each technology. Determine the performance range of available technologies. Identify the most promising technologies and promising trends in technology advances. Examine market forces and market trends. Develop a continuously growing in-house database to be used throughout the project. A variety of information sources have been used in these technology characterizations, including miscellaneous periodicals, manufacturer catalogs and cut sheets, other research documents, and data from previous computer simulations. We include these different sources in order to best show the type and variety of data available, however publication here does not imply our guarantee of these data. Within each category, several broad classes are identified, and within each class we examine the generic individual technologies that fall into that class.

Another Side of Light - D

D. Three quantum phenomena D. Three quantum phenomena In fluorescence, matter absorbs light waves of a high frequency and then emits light of the same or lower frequency. This process was studied and named by George Gabriel Stokes in the mid-19th century. Today, fluorescence is familiar to us from fluorescent light bulbs. A fluorescent bulb's filament produces ultraviolet light, which is absorbed by the bulb's inner coating, which then emits lower-frequency visible light-more visible light than an incandescent bulb produces with the same wattage. According to the hypothesis of light quanta, during fluorescence an atom absorbs a quantum of light whose energy is proportional to the light wave's frequency. If the atom doesn't supply any extra energy of its own, the light quantum emitted should either have the same energy or less energy

Replacing 15 inefficient incandescent bulbs in your home with energy-saving bulbs could save you about $50 per year. For the greatest savings, replace your old incandescent bulbs with ENERGY STAR-qualified bulbs. An average household dedicates about 10% of its energy budget to lighting. Switching to energy-efficient lighting is one of the fastest ways to cut your energy bills. Timers and motion sensors save you even more money by reducing the amount of time lights are on but not being used.

Shedding a new light on hazardous waste  

DOE Green Energy (OSTI)

The sun's ability to detoxify waterborne chemicals has long been known; polluted streams, for example, become cleaner as they flow through sunlit areas. Solar detoxification harnesses this natural degradation process for beneficial ends, producing simple, nonhazardous substances from hazardous organic chemicals. Solar detoxification systems now being developed break down these chemicals without using the fossil fuels required by conventional technologies. Sunlight destroys hazardous waste because of the distinctive properties of photons, the packets of energy that make up sunlight. Low-energy photons add thermal energy that will heat toxic chemicals; high-energy photons add the energy needed to break the chemical bonds of these chemicals. The detoxification process discussed here takes advantage of this latter group of photons found in the ultraviolet portion of the solar spectrum. 4 figs.

Light amplification using semiconductors  

Science Conference Proceedings (OSTI)

During the summer of 1953, John von Neumann discussed his ideas concerning light amplification using semiconductors with Edward Teller. In September of that year, von Neumann sent a manuscript containing his ideas and calculations on this subject to Teller for his comments. To the best of our knowledge, von Neumann did not take time to work further on these ideas, and the manuscript remained unpublished. These previously unpublished writings of John von Neumann on the subject of light amplification in semiconductors are printed as a service to the laser community. While von Neumann's original manuscript and his letter to Teller are available to anyone who visits the Library of Congress, it is much more convenient to have this paper appear in an archival journal.

This paper reports on the development of a visualization system for architectural lighting designers. It starts by motivating the problem as both complex in its physics and social organization. Three iterations of prototypes for displaying time and space varying phenomena are discussed. Fieldwork is presented to identify where in practice they will be most effective. A set of user studies, one of which is analyzed in fine-grained detail, show how building designers incorporate visualization on hypothetical design problems. This has positive implications for both energy efficiency and lighting quality in buildings.

Clusters in Light Nuclei  

E-Print Network (OSTI)

A great deal of research work has been undertaken in the alpha-clustering study since the pioneering discovery, half a century ago, of 12C+12C molecular resonances. Our knowledge of the field of the physics of nuclear molecules has increased considerably and nuclear clustering remains one of the most fruitful domains of nuclear physics, facing some of the greatest challenges and opportunities in the years ahead. In this work, the occurence of "exotic" shapes in light N=Z alpha-like nuclei is investigated. Various approaches of superdeformed and hyperdeformed bands associated with quasimolecular resonant structures are presented. Results on clustering aspects are also discussed for light neutron-rich Oxygen isotopes.

Light from cosmic strings  

Science Conference Proceedings (OSTI)

The time-dependent metric of a cosmic string leads to an effective interaction between the string and photons--the ''gravitational Aharonov-Bohm'' effect--and causes cosmic strings to emit light. We evaluate the radiation of pairs of photons from cosmic strings and find that the emission from cusps, kinks and kink-kink collisions occurs with a flat spectrum at all frequencies up to the string scale. Further, cusps emit a beam of photons, kinks emit along a curve, and the emission at a kink-kink collision is in all directions. The emission of light from cosmic strings could provide an important new observational signature of cosmic strings that is within reach of current experiments for a range of string tensions.

Light-Matter Quantum Interface  

E-Print Network (OSTI)

We propose a quantum interface which applies multiple passes of a pulse of light through an atomic sample with phase/polarization rotations in between the passes. Our proposal does not require nonclassical light input or measurements on the system, and it predicts rapidly growing unconditional entanglement of light and atoms from just coherent inputs. The proposed interface makes it possible to achieve a number of tasks within quantum information processing including teleportation between light and atoms, quantum memory for light and squeezing of atomic and light variables.

Physics of light  

Science Conference Proceedings (OSTI)

A fourth interpretation for the principle of light invariance is proposed. After Maxwell equations, relativity, Lorentz group, another possibility stands into consider the Lorentz group representations as species. By specie one means fields with same nature under light invariance. For instance, given a ((1/2),(1/2)) representation, instead of just one specific field, we should associate to it the potential fields specie. Thus, starting from such fields specie interpretation the features of a certain potential field A{sub {mu}I} will be determined in terms of its associated fields set {l_brace}A{sub {mu}I}{r_brace}, where I means a diversity index. It says that, the original field equation to be searched for a given field description is that one corresponding to the associated group of fields, and not more, for the field being taken isolated. It introduces the meaning of parts enfolded in the whole through whole relativistic equations. There is a more primitive equation to be understood. Instead Maxwell equation this fourth light invariance interpretation is guiding us to a more basic equation describing a fields set {l_brace}A{sub {mu}I}{r_brace}. It will be entitled as Global Maxwell equation. Three steps are necessary for characterizing this Global Maxwell equation. The first one is to derive on abelian terms a generic expression for the fields set {l_brace}A{sub {mu}I}{r_brace}. Further, show the diversity between these associated fields. Prove that every field carries a different quantum number (spin, mass, charges; C, P, T, CPT). The third one is on the photon singularity. Being the light invariance porter, it should be distinguished from others fields. This is done through the group gauge directive symmetry and Noether current. A Global Lorentz force complements the Global Maxwell by introducing three types of force. The first one generalizes the usual Lorentz force while the last two introduce relationships between fields and masses and fields with fields. A Physics of Light is derived. Based on such interpretation relating fields with same Lorentz nature, the electromagnetism is enlarged. The electromagnetic phenomena is not more restricted to Maxwell and electric charge. It englobes Maxwell and produces new types of electromagnetic fields and sectors. It centers the photon at its origin, new aspects as photonic charges and selfinteracting photons are obtained. As a case of this new electromagnetic spectrum one can take the set {l_brace}{gamma}Z{sup 0},W{sup {+-}}{r_brace}. It provides an electromagnetism involving photonic, massive, neutral, electric charged sectors which may antecede the electroweak unification.

"It's tempting to jump right back in when you get the green light," Tindal said. "We were in an abnormal state that really shook people. Focusing on people came first." Production began with return-to-work briefings. "During the briefings, we asked employees what they were concerned about, what was causing them stress," Tindal said.

Advanced optical daylighting systems: light shelves and light pipes  

SciTech Connect

We present two perimeter daylighting systems that passively redirect beam sunlight further from the window wall using special optical films, an optimized geometry, and a small glazing aperture. The objectives of these systems are (1) to increase daylight illuminance levels at 4.6-9.1 m (15-30 ft) from the window aperture with minimum solar heat gains and (2) to improve the uniformity of the daylighting luminance gradient across the room under variable solar conditions throughout the year. The designs were developed through a series of computer-assisted ray-tracing studies, laser visualization techniques, and photometric measurements and observations using physical scale models. Bi-directional illuminance measurements in combination with analytical routines were then used to simulate daylight performance for any solar position, and were incorporated into the DOE-2.1E building energy analysis computer program to evaluate energy savings. Results show increased daylight levels and an improved luminance gradient throughout the year compared to conventional daylighting systems.

Light Neutralinos in the NMSSM  

E-Print Network (OSTI)

Next-to-Minimal Supersymmetric Standard Model neutralino dark matter candidates in the (1-15) GeV range are found with a Markov Chain Monte Carlo scanning code. A very light, singlet-like Higgs and/or CP-odd Higgs is needed in order to achieve such light masses. Light scalar Higgses can yield large direct detection cross sections, suitable for an account of the recent claims for signals. Neutralino annihilations via resonant light pseudoscalar Higgs exchanges can overproduce the indirect yield of gamma-rays from dwarf spheroidal galaxies. Hence, direct and indirect detection experiments probe different configurations of the NMSSM with a light neutralino DM candidate.

E-Print Network (OSTI)

In this paper, we present a lighting design framework for neardiffuse real objects, starting from a set of prerecorded photographs of an object under various lighting conditions. Light sources are placed at fixed positions around an object, for which the intensities are to be determined. Using existing digital imaging software, the lighting designer paints the desired illumination distribution on a photograph of an object. This painted-on illumination is used to determine the light intensities which produce a shading of the real object matching the desired illumination distribution. Certain areas in the painted image can be favored among others by weighting their importance in the optimization algorithm.

Electric Lighting Quality Electric Lighting Quality The CUSD lighting design team utilized energy efficient products that meshed well with our daylighting scheme. We chose to use fluorescent tubes or compact fluorescent bulbs with an energy consumption of between 15 and 30 Watts throughout the house. The ballasts for all lamps dim to a 1% light output, so the interior and exterior lights can be adjusted as the level of available daylight fluctuates. Light sensors have been placed in front of our two largest apertures, allowing us to control how much artificial light is supplied to each space. The control of our ballasts is intricate, but refined and tested to avoid dysfunctional dimming or switching. While automatic controls are included, manual user overrides are provided in case the occupant prefers

Annual daylighting performance of a passive optical light shelf in sidelit  

NLE Websites -- All DOE Office Websites (Extended Search)

Annual daylighting performance of a passive optical light shelf in sidelit Annual daylighting performance of a passive optical light shelf in sidelit perimeter zones of commercial buildings Title Annual daylighting performance of a passive optical light shelf in sidelit perimeter zones of commercial buildings Publication Type Report Year of Publication 2013 Authors McNeil, Andrew, and Eleanor S. Lee Keywords bidirectional scattering distribution functions, building energy efficiency, daylighting, Radiance simulations Abstract Sunlight redirecting systems have the potential to significantly offset electric lighting energy use in deep perimeter zones of buildings where the windows are subject to high daylight availability. New Radiance modeling tools have recently been developed and validated, enabling accurate and timely simulation analysis of the annual energy and comfort performance of these optically-complex, anisotropic systems. A parametric study was conducted using these tools to evaluate the performance of a commercially-available passive optical light shelf (OLS) in a 17.4 m deep (57 ft), south-facing open plan office zone in three climates. Daylighting efficiency, discomfort glare, and lighting energy savings with continuous dimming and bi-level switching controls were determined at varying depths within the zone. The OLS decreased lighting energy use significantly throughout the depth of the space and achieved these savings with minimal discomfort glare in the area near the window. Annual lighting energy use intensity was reduced to 1.71-1.82 kWh/ft2-yr (22-27%) over the full depth of the perimeter zone across the three climates modeled (Phoenix, Washington DC, and Minneapolis) compared to a non-daylit zone at 2.34 kWh/ft2-yr. There was a greater occurrence of discomfort glare (3-7% during daytime work hours) if the occupant was in a seated view position looking at the window from the back of the room. The system is passive, needing no adjustment during the day and over the seasons and can be used as a retrofit measure in existing buildings. These results are encouraging and demonstrate how the primary daylit sidelit area can be extended well beyond the defined limits provided by the newly adopted ASHRAE 90.1-2010 code (i.e., 1.0 times the head height of the window).

Light Meson Distribution Amplitudes  

E-Print Network (OSTI)

We calculated the first two moments of the light-cone distribution amplitudes for the pseudoscalar mesons ($\\pi$ and $K$) and the longitudinally polarised vector mesons ($\\rho$, $K^*$ and $\\phi$) as part of the UKQCD and RBC collaborations' $N_f=2+1$ domain-wall fermion phenomenology programme. These quantities were obtained with a good precision and, in particular, the expected effects of $SU(3)$-flavour symmetry breaking were observed. Operators were renormalised non-perturbatively and extrapolations to the physical point were made, guided by leading order chiral perturbation theory. The main results presented are for two volumes, $16^3\\times 32$ and $24^3\\times 64$, with a common lattice spacing. Preliminary results for a lattice with a finer lattice spacing, $32^3\\times64$, are discussed and a first look is taken at the use of twisted boundary conditions to extract distribution amplitudes.

Radioluminescent lighting for Alaskan runway lighting and marking  

SciTech Connect

Alaska and other far northern areas have special logistical, environmental, and economic problems that make radioluminescent (RL) lighting applications, especially in the area of airport lighting, an attractive alternative to electrical systems and flare pots. Tests and demonstrations of prototype systems conducted in Alaska over the past two years have proved the basic technological worth of RL airport lighting systems for civilian and military use. If regulatory issues and other factors identified during these tests can be favorably resolved and if the system and its components can be refined through production engineering, attractive applications for RL airfield lighting systems in Alaska and other remote locations could result.

Light-Like Noncommutativity, Light-Front Quantization and New Light on UV/IR Mixing  

E-Print Network (OSTI)

We revisit the problem of quantizing field theories on noncommutative Moyal spacetime with \\emph{light-like} noncommutativity. To tackle the issues arising from noncommuting and hence nonlocal time, we argue that for this case light-front quantization procedure should be employed. In this appropriate quantization scheme we perform the non-planar loop analysis for the light-like noncommutative field theories. One of the important and peculiar features of light-front quantization is that the UV cutoff of the light-cone Hamiltonian manifests itself as an IR cutoff for the light-cone momentum, $p^+$. Due to this feature, the naive results of covariant quantization for the light-like case allude to the absence of the UV/IR mixing in the light-front quantization. However, by a careful analysis of non-planar loop integrals we show that this is not the case and the UV/IR mixing persists. In addition, we argue in favour of the perturbative unitarity of light-like noncommutative field theories in the light-front quantization scheme.

Lighting energy management: a comprehensive approach  

SciTech Connect

This article points out the difference between lighting energy management and lighting energy conservation. The goal of lighting energy conservation is to develop a lighting system which consumes less energy, and thus saves money. Lighting energy management recognizes that lighting was installed for a purpose, so the goal becomes attaining more of that purpose while minimizing waste. The benefits of lighting energy management can go far beyond operation and maintenance (O and M) cost savings. If the lighting system provides less light than is needed, and/or provides low quality lighting, then new light will improve productivity.

Lighting networks: A new approach for designing lighting algorithms  

E-Print Network (OSTI)

In the past, new global illumination algorithms have usually been designed as a single module that was responsible for the simulation of all aspects of illumination in a scene. A recently developed alternative is the design of small and specialized algorithms (lighting operators) together with an infrastructure for creating more complex algorithms by connecting these building blocks--the Lighting Network. In this paper, we discuss the benefits of the Lighting Network approach for designing new and improved global illumination algorithms. Lighting Networks not only provide a flexible infrastructure for new algorithms, they also support a better theoretic understanding of the lighting simulation process. We show that a small number of global light propagation operators already provides the basis for creating many of todays illumination algorithms. Their illumination results are converted into more suitable representations by purely local conversion operators that are specific to an illumination algorithm. Varying the composition of these operators and introducing new elements allows us to create and explore the benefits of new simulation algorithms. We demonstrate the potential of Lighting Networks with several examples, implementing a diverse set of algorithms, such as density estimation, irradiance gradients, and a composite lighting simulation.

Monitored lighting energy savings from dimmable lighting controls in The Monitored lighting energy savings from dimmable lighting controls in The New York Times Headquarters Building Title Monitored lighting energy savings from dimmable lighting controls in The New York Times Headquarters Building Publication Type Journal Article LBNL Report Number LBNL-6171E Year of Publication 2013 Authors Fernandes, Luis L., Eleanor S. Lee, Dennis L. DiBartolomeo, and Andrew McNeil Journal Energy and Buildings Volume 68 Issue A Pagination 498-514 Date Published 01/2014 Keywords Building energy-efficiency, daylighting, lighting control systems Abstract Digital addressable, dimmable lighting controls were introduced to the US market in the early 2000s with the promise of facilitating capture of potential energy savings with greater flexibility over their historic, typically unreliable, analog counterpart. The New York Times Company installed this emerging technology, after having tested the system thoroughly prior to procurement, in their new building in New York, New York. Four years after full occupancy in 2007, the owner agreed to participate in a post-occupancy monitored evaluation of the dimmable lighting system to verify actual performance in the field. Annual lighting energy savings from daylighting, setpoint tuning and occupancy controls were determined for the daylit, open-plan office areas on three typical floors (6, 11, and 20th floors) of the 51-story high-rise tower. Energy savings were calculated from ballast control signal and occupancy data recorded by the manufacturer's lighting control system. The ballast data were calibrated with independent measurements of lighting energy consumption. Savings from dimming controls (daylighting and setpoint tuning) were 12.6 kWh/m2-yr (1.17 kWh/ft2-yr) for the daylit spaces on the three floors overall, or 20%, relative to ASHRAE 90.1-2007. Compared to the prescriptive code in effect at the time of the building's construction (ASHRAE 90.1-2001), savings were 21.0 kWh/m2-yr (1.95 kWh/ft2-yr) or 28%. Annual lighting energy use with all lighting control strategies was 33.9 kWh/m2-yr (3.15 kWh/ft2-yr) in the daylit, open plan zones on average for the three floors. A simple payback analysis was conducted.

Types of Lighting in Commercial Buildings - Lighting Types  

U.S. Energy Information Administration (EIA) Indexed Site

Lighting Types Lighting Types The following are the most widely used types of lighting equipment used in commercial buildings. Characteristics such as energy efficiency, light quality, and lifetime vary by lamp type. Standard Fluorescent A fluorescent lamp consists of a sealed gas-filled tube. The gas in the tube consists of a mixture of low pressure mercury vapor and an inert gas such as argon. The inner surface of the tube has a coating of phosphor powder. When an electrical current is applied to electrodes in the tube, the mercury vapor emits ultraviolet radiation which then causes the phosphor coating to emit visible light (the process is termed fluorescence). A ballast is required to regulate and control the current and voltage. Two types of ballasts are used, magnetic and electronic. Electronic ballasts

Types of Lighting in Commercial Buildings - Lighting Characteristics  

U.S. Energy Information Administration (EIA) Indexed Site

Characteristics of Lighting Types Characteristics of Lighting Types Efficacy Efficacy is the amount of light produced per unit of energy consumed, expressed in lumens per watt (lm/W). Lamps with a higher efficacy value are more energy efficient. Average Rated Life The average rated life of a particular type of lamp is defined by the number of hours when 50 percent of a large sample of that type of lamp has failed. Color Rendering Index (CRI) The CRI is a measurement of a light source's accuracy in rendering different colors when compared to a reference light source. The highest attainable CRI is 100. Lamps with CRIs above 70 are typically used in office and living environments. Correlated Color Temperature (CCT) The CCT is an indicator of the "warmth" or "coolness" of the color

Light-by-Light Scattering Effect in Light-Cone Supergraphs  

E-Print Network (OSTI)

We give a relatively simple explanation of the light-cone supergraph prediction for the UV properties of the maximally supersymmetric theories. It is based on the existence of a dynamical supersymmetry which is not manifest in the light-cone supergraphs. It suggests that N=4 supersymmetric Yang-Mills theory is UV finite and N=8 supergravity is UV finite at least until 7 loops whereas the $n$-point amplitudes have no UV divergences at least until $L=n+3$. Here we show that this prediction can be deduced from the properties of light-cone supergraphs analogous to the light-by-light scattering effect in QED. A technical aspect of the argument relies on the observation that the dynamical supersymmetry action is, in fact, a compensating field-dependent gauge transformation required for the retaining the light-cone gauge condition $A_+=0$.

How plants grow toward light  

NLE Websites -- All DOE Office Websites (Extended Search)

How plants grow toward light How plants grow toward light Name: schwobtj Location: N/A Country: N/A Date: N/A Question: When a seed is planted below the surface of the ground, how does it "know" to grow toward the light? Replies: Plants don't know where the light is, they do respond to gravity. Since light is usually up, a plant seed grows up and finds light enough to keep things going. Psych One way that plants below ground can tell which way is up is with the use of STATOLITHS. Statoliths are dense pieces of material that settle to the bottom of a STATOCYST. In plants, pieces of starch or another material denser than water will settle to the bottom of the cell. Somehow the plant cell determines on what side the statolith has fallen, and then somehow relays a message (probably a chemical) that tells the bottom cells to grow faster than the top cells, therefore causing upward growth. There is still quite a lot of mystery in there to be discovered. I got this explanation from BIOLOGY by Neil Campbell. This is similar to the way in which plants use chemical signals to help them grow towards light.

Lighting for remote viewing systems

Scenes viewed by television do not provide the same channels of information for judgment of distances as scenes viewed directly, since television eliminates or degrades several depth perception cues. However, it may be possible to improve depth perception of televised scenes by enhancing the information available through depth cues that are available from lighting. A literature survey and expert opinions were integrated to design a remote lighting arrangement which could enhance depth perception of operators performing remote handling operations. This paper describes the lighting arrangement and discusses some of its advantages and disadvantages. 10 references, 2 figures.

Stopping Light All-Optically  

E-Print Network (OSTI)

We show that light pulses can be stopped and stored all-optically, with a process that involves an adiabatic and reversible pulse bandwidth compression occurring entirely in the optical domain. Such a process overcomes the fundamental bandwidth-delay constraint in optics, and can generate arbitrarily small group velocities for light pulses with a given bandwidth, without the use of any coherent or resonant light-matter interactions. We exhibit this process in optical resonator systems, where the pulse bandwidth compression is accomplished only by small refractive index modulations performed at moderate speeds.

The Momentum of Light - C

C. More direct evidence C. More direct evidence As we've noted, relativity theory implies that a quantum of energy ought to be a quantum of momentum as well. While Einstein's analysis showed that this idea was consistent with known facts about light and matter, modern experiments with individual light quanta and subatomic particles demonstrate the existence of momentum quanta more directly. One early demonstration was an effect studied by Arthur Holly Compton. When x-rays a high-frequency form of light-collide with atoms, the x-rays scatter in all directions accompanied by electrons from the atoms. The wavelength of the scattered x-rays and the momentum of the electrons both vary with their direction of motion. While the classical theory of light and electricity doesn't explain the variation actually observed, the

Lighting Controls in Commercial Buildings Lighting Controls in Commercial Buildings Title Lighting Controls in Commercial Buildings Publication Type Report Year of Publication 2012 Authors Williams, Alison A., Barbara A. Atkinson, Karina Garbesi, Erik Page, and Francis M. Rubinstein Series Title The Journal of the Illuminating Engineering Society of North America Volume 8 Document Number 3 Pagination 161-180 Date Published January ISBN Number 1550-2716 Keywords controls, daylighting, energy, occupancy sensors, tuning. Abstract Researchers have been quantifying energy savings from lighting controls in commercial buildings for more than 30 years. This study provides a meta-analysis of lighting energy savings identified in the literature-240 savings estimates from 88 papers and case studies, categorized into daylighting strategies, occupancy strategies, personal tuning, and institutional tuning. Beginning with an overall average of savings estimates by control strategy, successive analytical filters are added to identify potential biases introduced to the estimates by different analytical approaches. Based on this meta-analysis, the bestestimates of average lighting energy savings potential are 24 percent for occupancy, 28 percent for daylighting, 31 percent for personal tuning, 36 percent for institutional tuning, and 38 percent for multiple approaches. The results also suggest that simulations significantly overestimate (by at least 10 percent) the average savings obtainable from daylighting in actual buildings.

Lighting energy management for colleges and universities  

SciTech Connect

The degree to which lighting satisfies the diverse illumination requirements of colleges and universities depends on the quality of lighting involved, how well it is designed, and how well it is maintained. It is unfortunate that lighting quality is often made secondary to energy consumption because the two are totally compatible if the difference between lighting energy conservation and lighting energy management is understood. Lighting energy management considers lighting interrelationships as well as illumination technology, and requires three types of knowledge: lighting systems and their components, lighting's impact on activities and safety, and an awareness of the existing lighting systems. The authors develop these concepts and present a variety of lighting options and guidelines for designing a lighting system. 16 figures, 3 tables.

Cooling energy savings potential of light-colored roofs for residential and commercial buildings in 11 US metropolitan areas  

SciTech Connect

The U.S. Environmental Protection Agency (EPA) sponsored this project to estimate potential energy and monetary savings resulting from the implementation of light-colored roofs on residential and commercial buildings in major U.S. metropolitan areas. Light-colored roofs reflect more sunlight than dark roofs, so they keep buildings cooler and reduce air-conditioning demand. Typically, rooftops in the United States are dark, and thus there is a potential for saving energy and money by changing to reflective roofs. Naturally, the expected savings are higher in southern, sunny, and cloudless climates. In this study, we make quantitative estimates of reduction in peak power demand and annual cooling electricity use that would result from increasing the reflectivity of the roofs. Since light-colored roofs also reflect heat in the winter, the estimates of annual electricity savings are a net value corrected for the increased wintertime energy use. Savings estimates only include direct reduction in building energy use and do not account for the indirect benefit that would also occur from the reduction in ambient temperature, i.e. a reduction in the heat island effect. This analysis is based on simulations of building energy use, using the DOE-2 building energy simulation program. Our methodology starts with specifying 11 prototypical buildings: single-family residential (old and new), office (old and new), retail store (old and new), school (primary and secondary), health (hospital and nursing home), and grocery store. Most prototypes are simulated with two heating systems: gas furnace and heat pumps. We then perform DOE-2 simulations of the prototypical buildings, with light and dark roofs, in a variety of climates and obtain estimates of the energy use for air conditioning and heating.

Lighting Choices Lighting Choices Energy 101: Lighting Choices Addthis Below is the text version for the Energy 101: Lighting Choices video: The video opens with "Energy 101: Lighting Choices." This is followed by shots of a variety of lamps being turned on. We're all used to lighting up dark spaces with the flip of a switch. In fact, people have been doing so since Thomas Edison invented the incandescent light bulb about 130 years ago...and we've used that same old bulb ever since. The video shows a store aisle with a diverse light bulb selection, then moves to close-ups of the packaging labels on various bulbs. Today you'll see more light bulb options in stores. These bulbs will give you the light you want while saving you energy...and money. A hand screws in a light bulb and flips the switch. The bulb is shown in

Enrichment of light hydrocarbon mixture  

Science Conference Proceedings (OSTI)

Light hydrocarbon enrichment is accomplished using a vertically oriented distillation column having a plurality of vertically oriented, nonselective micro/mesoporous hollow fibers. Vapor having, for example, both propylene and propane is sent upward through the distillation column in between the hollow fibers. Vapor exits neat the top of the column and is condensed to form a liquid phase that is directed back downward through the lumen of the hollow fibers. As vapor continues to ascend and liquid continues to countercurrently descend, the liquid at the bottom of the column becomes enriched in a higher boiling point, light hydrocarbon (propane, for example) and the vapor at the top becomes enriched in a lower boiling point light hydrocarbon (propylene, for example). The hollow fiber becomes wetted with liquid during the process.

Shedding Light on Nanocrystal Defects  

NLE Websites -- All DOE Office Websites (Extended Search)

Shedding Light on Nanocrystal Shedding Light on Nanocrystal Defects Shedding Light on Nanocrystal Defects Print Thursday, 20 June 2013 10:41 Nanocrystals have been the focus of much scientific interest lately, given their various advantageous mechanical properties. Their resistance to stress has had researchers proposing nanocrystals as a promising new protective coating for advanced gas turbine and jet engines. But recent studies conducted at the ALS show that the tiny size of nanocrystals does not safeguard them from defects. Engineering Nanocrystal Materials Most nanocrystal materials are made up of small crystals, called "grains," and what happens at the boundaries between these grains is critical to material properties. Based on computer simulations and electron microscopy analysis, the belief has been that dislocation-mediated plastic deformation becomes inactive below a grain size of at least 10 nanometers, and possibly as large as 30 nanometers.
