摘　　要：开发一种利用个人计算机模拟汽车头灯光照分布的方法， 建立了灯泡和反射镜的最优模型， 然后根据计算机模拟光线追迹来计算照明分布结果， 并与头灯配光标准比较。考虑到灯泡的安装误差， 对头灯光进行了灯丝的位置误差分析。这种方法可验证多反射镜计算机辅助设计的精度和可靠度。This paper presents computer simulation of auto headlight lighting Through establishing optimal models of the bulb and the reflector,we were able to perform computer?aided ray tracing and ray attenuation operations to calculate illuminance distribution.Moreover,comparisons were made to determine the computer simulation analysis results and the matching of different parts,as well as the relative distribution of light rays.In this way,the accuracy and reliability of the computer simulation analysis could be verified.
