摘　　要：激光大灯的光源激光二极管(Laser diode)与发光二极管(LED)几乎诞生于同一时代,虽然激光二极管的大规模商业化应用要比LED稍晚些,但是其应用范围更加广泛,在测量、电子、通信、医学、加工等行业都有激光二极管的身影。激光大灯拥有LED大灯大部分的优点,比如响应说速度快、亮度衰减低、体积小、能耗低、寿命长等等。激光大灯在体积方面具有优势,单个激光二极管元件的长度已经可以做到10微米,仅为常规LED元件尺寸的1/100,这意味着,只要设计师愿意,传统汽车的大灯的尺寸可以大幅度缩小,这也许将为汽车前脸上各个元素设计比例带来革命性的变化。The light source of laser headlights is laser diode,it was invented almost at the same time as LED,although large scale commercial application of laser headlights is later than LED,it has wider application scale,eg,Measurement,Electronics,Communication,Medicine and Processing.Laser headlights used on cars have most of the advantages as LED headlights,such as high speed,low brightness attenuation,small volume,low energy consumption and long service life.Laser headlights also have advantage on volume,the length of diode element of single laser could already be 10 microns,1/100 of routine LED.Which means,traditional headlights could be greatly reduced.This may bring a revolutionary change to the design proportion of each element on the front face of auto.
