摘要: 介绍了电子防眩目后视镜的原理。电子防眩目后视镜利用光敏电阻来检测汽车前后方的光线强弱,当后方光 线强度大于前方光线强度时,根据前后方光线强度差的绝对值输出电压到镜片上,利用镜片通电改变透光率( 变 色) ,可以起到降低反射率的效果,以吸收强光,消减强光的反射,达到防眩目的效果。

Abstract: The principle of the electronic anti-dazzling rear-view mirror is studied. The electronic anti-dazzling rear-view mirror makes use of two photoresists to detect the front and back light intensity of the car. When the back light intensity is more than the light intensity of the front, according to the absolute value of difference of front and back the light intensity, output voltage to the glass, electro-chromic change light is used to change the transmittance,which can reduce the reflectivity of the light. Therefore, anti-dazzling performance is realized.

Key words: photoresist, anti-dazzling, light intensity
