UV enhancer for a metal halide lamp
A starting aid for a metal halide lamp (10) uses iodine and an inert gas instead of mercury so that the entire metal halide lamp (10) may be mercury-free. The starting aid is a UV enhancer (20) that includes a UV-transmissive capsule (22) with a cavity (24) in which iodine and an inert gas are seale...

| Zusammenfassung: | A starting aid for a metal halide lamp (10) uses iodine and an inert gas instead of mercury so that the entire metal halide lamp (10) may be mercury-free. The starting aid is a UV enhancer (20) that includes a UV-transmissive capsule (22) with a cavity (24) in which iodine and an inert gas are sealed, wherein the iodine emits UV radiation when excited to reduce a starting voltage of the lamp (10). |
