250 Watt 메탈할라이드 램프용 전자식 Dimming 안정기 개발
The Development of Dimmable Electronic Ballast for 250W Metal Halide Lamp

초록
In this paper, the dimmable electronic ballast for the 250W metal halide lamp was realized by three stage structure. We developed stable the dimming ballast by using a Micro-controller, and measured the output wattage in the dimming range(illumination) from 100% to about 20%. Under the 35% dimming level, it is possible to cause the redution of lamp's life. The dimming performance can reduce the light system's wattage but can reduce the luminance efficiency (lux/watt).
