汽车自动变光器电路的设计分析

Design and Analysis of Automobile Automatic Dimmer Switch Circuit

介绍了新设计的汽车自动变光器控制电路的结构，依据该电路的逻辑变换，对其中４种工作状态进行了比较详细的分析．该自动变光器，可以使在夜间行驶的汽车能根据对面来车灯光变化，自己实现远。

This paper introduces the structure of an automatic dimmer switch which is applied in an automobile and designed by the author. According to the logical conversion of the circuit, four working states are analyzed in detail. With this automatic dimmer switch, when you take a night driving, the head light of your atuomobile should shift between lower beam and upper beam automatically according to the light of opposed vehicle, so that it can guarantee nighttime meeting with dipped beam and night driving safely.
