一种汽车用金卤灯的快速点亮电路

A Kind of Quick-lighting Circuit of Metal-halide Lamp for Use in Vehicles

对汽车前照灯用的金属卤化物灯的性能特点和普通触发点亮电路的致命缺点作了简要说明。介绍了一种能快速点亮金卤灯的电路,可在0.3s 内使灯的光输出达到现用卤钨灯的水平,在3s～5s 使灯的光输出达到其额定值。

The property characteristic of a matel-halide lamp for use in the head lamps of vehicles and the fatal weakness of con- ventional lighting circuit for use in a metal halide lamp is explained.A kind of quick-lighting circuit of metal-halide lamp for use in vehicles is introduced,h can make a lamp lighted,light flux reached the level of the wolframic-halide lamp in 0.3s,and light flux reached rated output in 3s～5s.
