Hybrid fibre lighting - directed towards a smaller ecological foot print; Hybrid fiber belysning - rettet mod et mindre oekologisk fodaftryk

Abstract

Building on one of the world-leading technologies in fiber optics this project uncovers, whether it is realistic under Danish conditions to exploit opportunities within hybrid fiber illumination - i.e. systems that directly moves the sun indoors via fiber optics. Hybrid lighting is a combination of four technologies: the collection of sunlight (daylight), generation of artificial light, assembly, transportation and distribution of light where needed, and operational control of both natural and artificial light. Some of the significant findings from this project are a design of a hybrid system based on a solar optical system and LED technology, and design and development of fixtures that could combine both daylight and artificial light. The analysis showed that a system based on only LEDs could save 36% energy compared with a system based on the T5 (fluorescent lamps), which today is considered the best available technology. The analysis further indicates an energy saving of 59% when you combine a solar optical system with LED technology in a hybrid system. It is found that there is great potential for further design and applications which can be based for a hybrid lighting combined with the two technologies mentioned above (optical fibers and LEDs).

The analysis further indicates an energy saving of 59% when you combine a solar optical system with LED technology in a hybrid system. It is found that there is great potential for further design and applications which can be based for a hybrid lighting combined with the two technologies mentioned above (optical fibers and LEDs). It was also found that hybrid lighting systems are in a very early stage of the innovation life cycle and that one of the most important barriers for successful implementation is the considerably high price. However, this is a typical problem that arises with new technologies and, therefore, further development followed by pilot test projects could bring this technology fast to a more competitive phase, even if one as the basis selects systems based on the T5 technology. There is widespread acceptance of the hybrid system by office users in many areas where it is not possible to have windows, but to make the system work in other sectors, it is necessary to continue research in design that can provide a greater light intensity and better color, while being careful to achieve a better light distribution. This is true both in the assembly of daylight, fiber and LED technologies, and fixture design. (ln)}
