Abstract

High-pressure mercury (HPM) lamps use a phosphor on their outer envelope for the sake of improvement of efficacy and color rendition. Although this is basically a rare earth phosphor, if its composition is changed in part, the LUMEN MAINTENANCE ratio of the lamp is improved by about 5% for 8000 hours of lighting. Factors in the LUMEN MAINTENANCE ratio are not the phosphor alone, but the influence of variation in amount on lamp characteristics have not been reported so far. In the current study, we attempted to determine the influence of these PHOSPHORS on various characteristics of a standard 400W lamp. With regard to LUMEN MAINTENANCE ratio of a lamp designed for about twice the life, the phosphor involved is identified as one of the components, and the optimum amount of change is verified from the practical application viewpoint. Results obtained indicate that an improvement of as much as about 20% is feasible. This provides a new finding useful for energy saving and reliability improvement.
