摘　　要：以抛物线的反光特性为基础,将抛物线旋转、平移,设计出一款矩形复合抛物面聚光器。由汽车用前照灯GB25991—2010对近光灯的光照要求及边缘光线原理计算出聚光器的主要参数。LED汽车近光灯系统采用2个LED矩形复合抛物面聚光器配光组合,经Tracepro光学仿真软件对近光灯光照进行模拟,结果显示水平及15°明暗截止线清晰,各测试点、区域的照度值符合GB25991—2010要求;近光灯配光系统无需挡板与透镜,降低了光能损耗,提高了光能利用率。Based on non imaging optics, edge light principle and reflective properties of parabola, a rectangular compound parabolic concentrator reflector was designed by rotating and translating parabo lic. The concentrator reflector＇s main parameters were calculated based on GB25991 -2010. The LED dipped headlight system comprised two composite rectangular compound parabolic reflectors＇ light dis- tribution based on composite rectangular compound parabolic. Simulation results via tracepro optical simulation software indicate that the horizontal and 15~ light and shade line is very clear with the illumination at testing points and zones conforming with the standards in GB25991 -2010. The dipped headlight＇s distribution system with no baffle and lens can improve the efficiency of light energy.
