內后視鏡簡介

后視鏡是駕駛員坐在駕駛室座位上直接獲取汽車后方、側方和下方等外部信息的工具。為了駕駛員操作方便，防止行車安全事故的發生，保障人身安全，各國均規定了汽車上必須安裝后視鏡，且所有后視鏡都必須能調整方向。
在夜間受到后車的前照燈照射時，后視鏡的反射光進入駕駛員的眼簾，易于造成炫目狀態，所以開發出防炫目內后視鏡。防炫目內后視鏡大致可以分為兩種：
（1）成本低且成為主流的截面為楔型的內后視鏡；
（2）從功能效用的觀點出發，僅在必要的景物時使用的采用了電控彩色發光元件或液晶元件的內后視鏡。
防眩目電(dian)(dian)(dian)(dian)動后(hou)視(shi)鏡(jing)由1個(ge)特殊的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)化(hua)(hua)層鏡(jing)面、2個(ge)光(guang)(guang)(guang)電(dian)(dian)(dian)(dian)傳感器(qi)以及電(dian)(dian)(dian)(dian)子控制(zhi)器(qi)組成。電(dian)(dian)(dian)(dian)子控制(zhi)器(qi)接收(shou)光(guang)(guang)(guang)敏二極管傳送的(de)(de)(de)(de)燈光(guang)(guang)(guang)照(zhao)射強度信號，如果后(hou)車燈光(guang)(guang)(guang)強于前車燈光(guang)(guang)(guang)，電(dian)(dian)(dian)(dian)子控制(zhi)器(qi)將輸出(chu)一個(ge)電(dian)(dian)(dian)(dian)壓(ya)到(dao)鏡(jing)面，改變(bian)鏡(jing)面電(dian)(dian)(dian)(dian)化(hua)(hua)層的(de)(de)(de)(de)顏(yan)(yan)色(se)。這(zhe)個(ge)電(dian)(dian)(dian)(dian)壓(ya)越高，電(dian)(dian)(dian)(dian)化(hua)(hua)層顏(yan)(yan)色(se)的(de)(de)(de)(de)改變(bian)越大。電(dian)(dian)(dian)(dian)化(hua)(hua)層的(de)(de)(de)(de)顏(yan)(yan)色(se)改變(bian)后(hou)，經過電(dian)(dian)(dian)(dian)動后(hou)視(shi)鏡(jing)反射到(dao)駕駛員(yuan)眼睛的(de)(de)(de)(de)光(guang)(guang)(guang)線就(jiu)顯(xian)著減(jian)弱(ruo)，不(bu)但(dan)不(bu)影響駕駛員(yuan)的(de)(de)(de)(de)視(shi)力，反而提高了駕乘車輛的(de)(de)(de)(de)舒適性(xing)和(he)安全性(xing)。
