Abstract

Metal-halide lamps produce light by discharging an electric arc through a gaseous mixture of vaporized mercury and metal halides. Metal-halide lamps for use in spaces with lower mounting heights can produce excessive visual glare in the normal, higher field-of-view unless they are equipped with prismatic lenses. Should the bulb fail, high internal operating pressure of the arc tube can launch fragments of arc tube at high velocity in all directions, striking the outer bulb of the lamp with enough force to cause the outer bulb to break. This article reports an investigation of a light fixture fire and reviews a case study of a metal-halide lamp fire. We reported on causal analysis of the metal-halide lamp fire uncovered contributing factors that created the environment in which the incident occurred. Latent organizational conditions that created error-likely situations or weakened defenses were identified and controlled. Lastly, effective improvements that reduce the probability or consequence of similar metal-halide lamp fire incidents were implemented.

Max Tech and Beyond: High-Intensity Discharge Lamps

Technical Report Scholand, Michael

High-intensity discharge (HID) lamps are most often found in industrial and commercial applications, and are the light source of choice in street and area lighting, and sports stadium illumination. HID lamps are produced in three types - mercury vapor (MV), high pressure sodium (HPS) and metal halide (MH). Of these, MV and MH are considered white-light sources (although the MV exhibits poor color rendering) and HPS produces a yellow-orange color light. A fourth lamp, low-pressure sodium (LPS), is not a HID lamp by definition, but it is used in similar applications and thus is often grouped with HID lamps. Withmore »« less

A metal halide lamp that provides unique lighting system brightness and uniformity opportunities

Journal Article Gotti, M B ; Paugh, R L - IEEE Trans. Ind. Appl.; (United States)

Typically, metal halide lamps exhibit a substantial loss in efficacy and reduction in life when operated horizontally. A novel lamp design is described that permits transverse mounting of the optimal arc tube design within an outer bulb. Combined with a prefocusing type mogul base, this lamp operates the arc tube vertically while the outer bulb is horizontal. Thus the high lamp efficacy, long life, and better lumen output maintenance throughout life previously only available in the vertical burning lamp is available in the horizontal burning type. From an application viewpoint, a lighting fixture designed to utilize a horizontal burning lampmore »« less

High lumen compact fluorescents boost light output in new fixtures

Book

Some compact fluorescent lamps aren`t so compact. General Electric (GE), OSRAM, and Philips have been expanding offerings in longer, more powerful, hard wired CFLs that generate enough light to serve applications once limited to conventional fluorescents and metal halide systems. All three of these manufacturers have for some time offered 18- to 40-watt high-output CFLs, which use a fluorescent tube doubled back on itself to produce a lot of light in a compact source. Now GE has introduced an even larger, more powerful 50-watt unit, and OSRAM is soon to follow suit with a 55-watt lamp. These new entries tomore »« less
North American Coal Corporation's Illumination Program

Conference Elliott, J R

Over the past 18 months the technology in mine illumination developed by MESA has been accepted and used by coal operators and manufacturers to comply with illumination standards. However, just as problems delayed the development of the technology, additional problems have occurred in its application. Since publication of the rules, there have been changes in interpretations. These interpretations have involved the inby end of the shuttle car and the distance from the face a mining machine can be. The BCOA and UMWA Joint Industry Health and Safety Committee have submitted a report that advocates changes in the law. MESA hasmore »« less
Investigation of a “Sharps” Incident

Journal Article Cournoyer, Michael Edward ; Trujillo, Stanley ; Schreiber, Stephen Bruce - Journal of Chemical Health and Safety

Special nuclear material research, process development, technology demonstration, and manufacturing capabilities are provided at the Los Alamos National Laboratory Plutonium Facility. Engineered barriers provide the most effective protection from radioactive and hazardous materials. The Worker Safety Security Team augments these passive safety feature by investigating incidents to identify appropriate prevention and mitigation measures. “Learning Teams” facilitate employee feedback loop and integration toward process improvement. Here, this article reports an investigation of a “Sharps” incident and reviews a case study of a technician that cuts his left thumb while making a gasket. Causal analysis of the sharps incident uncovered contributing factorsmore »« less
