In this paper, an automated optimization method in the sequential mode of ZEMAX is proposed in the design of an aspheric lens with uniform illuminance for an LED source. A feedback modification is introduced in the design for the LED extended source. The user-defined merit function is written out by using ZEMAX programming language macros language and, as an example, optimum parameters of an aspheric lens are obtained via running an optimization. The optical simulation results show that the illumination efficiency and uniformity can reach 83% and 90%, respectively, on a target surface of 40 mm diameter and at 60 mm away for a 1×1 mm LED source.
本文针对LED光源的非球面均匀照明透镜设计，提出了一种ZEMAX顺序模式下的自动优化方法。在设计中针对LED扩展光源引入了反馈修正。利用ZEMAX编程语言宏语言编写用户自定义的评价函数，并通过运行优化得到了非球面透镜的最佳参数。光学仿真结果表明，对于1×1mm的LED光源，在直径40mm、距离60mm的目标面上，照明效率和均匀度分别可达83%和90%。
