MERCURY-FREE OR LOW-MERCURY HIGH INTENSITY DISCHARGE LAMP

摘要

A kind of mercury-free or low-mercury high intencity discharge lamps includes a metal halide discharge lamp, a high pressure mercury lamp, a mercury-xenon lamp and so on. In use, the mercury-free or low-mercury high intencity discharge lamp confirms the most suitable use amount of selenium(Se) or mercury selenide(SeHg) according to the type and the power of the lamp to replace the mercury completely or partially, and the lamp can achieves proper light spectrum with high color rendering index(e.g. 95). The mercury-free or low-mercury high intencity discharge lamp can replace completely or reduce sharply mercury content and fits the developing trend of the environment protect, and it is a potential new-style light source.
