摘　　要：随着三维模拟、运算技术的发展,计算机辅助设计(CAD)逐步进入照明领域。借助相应的软件,不仅可以大大减少繁琐冗长的数字计算,方便快捷的生成各种反射面和透镜,而且能对各种效果(如光学、热学、机械等)进行模拟、分析,及时预测、修改设计方案。CAD技术的引入,降低了设计成本,缩短了设计周期,并且为复杂多变的造型设计提供了更大自由度。本文就用于汽车灯具光学元件CAD辅助设计做一些简单的介绍。With the development of 3D modeling and calculation techniques, Computer Aided Design begins to enter the lighting field. With the appropriate software, we could easily generate the reflective or refractive elements, while eliminating the necessity of complex and dull calculations. Furthermore simulation results (optical, thermal or mechanical) could give a preview about the performance, and engineers could make modifications in advance. CAD programs really speed up the design process and reduce the design ...
