奔驰电致变色自动防眩目后视镜

奔驰系列电致变色自动防眩目后视镜按原厂1：1模具设计和生产，可完全替换原厂无防眩目功能镜片，保留原车电加热功能。产品可根据后方光线强弱，自动调节镜子反射率，避免驾驶人员受强光刺激。

防眩目原理

防眩目后视镜由一面特殊的镜子和2个光敏二级管及电子控制器组成。光敏二级管感应到后方车辆的远光灯信号后，转换成电信号传送到电子控制器，电子控制器将输出一定值的电压到镜子的导电层上，从而改变镜子内导电液离子浓度，离子深度越大，镜子颜色越深，反射率减小，强光经过镜子反射之后，光线变弱，不再刺眼。当后方强光消失之后，电子控制器停止给导电液供电，镜子逐渐恢复到原来的反射率。

防眩目过程

镜片结构

①防眩目镜片由多层结构组成，外面是两层透明镜片玻璃，玻璃内侧涂有透明导电层，导电层之间夹着一层电子变色材料。
②无强光照射时，电子变色材料中的正负电子是无规则排列的，因而也是无色透明的。

防眩目过程

①有强光照射时，传感器感应到强光后，控制电路会自动给电子变色材料层施加一定电压，正负电子就向两侧聚集，从而使一侧带负电，另一侧带正电，这时两侧的颜色会因离子浓度变化而变化，从无色透明的状态变成不同的深颜色。
②颜色变深之后，防眩目镜片反射率就会降低，强光反射后就会减弱。
