LED 二次光学设计中的透镜设计，根据非成像光学原理，利用matlab计算生成二维点坐标，可导入3维建模软件-LED optical design, lens design, according to the non-imaging optics principle, the use of matlab calculation to generate two-dimensional coordinates can import 3-D modeling software, the production model. The code has been tested and successfully completed the calculation. We can refe
