摘要

摘要: 为在特定角度范围内实现所需照明，满足各类LED照明系统的要求，提出一种适用于扩展光源的透射全反射复合曲面的LED透镜设计方法。根据光源的大小由非成像光学原理确定反射面面型并计算光源发散角度，再根据照射的角度要求进行自由曲面的透镜设计。文章给出了设计思想及方法，并设计了一款出射半角为2.5的透镜实例，分析了误差对实际结果的影响。

Abstract: In order to achieve the required lighting in a specific angle range and meet the requirements of various types of LED lighting systems, we put forward a design method for total internal reflection (TIR) compound surface LED lens. According to the principles of non-imaging optics, we determined reflection surface type, calculated the divergence angle, and designed free-form surface lens. We provided the design idea and method, designed a LED lens with emergence half angle of 2.5 degree, and analyzed the influences of error on the actual results.
