Rapid optimization design for lighting system based on principles of sequential ray tracing

  • 摘要: 为解决LED扩展光源照明系统设计时,优化时间较长且多软件数据传输繁琐等问题,提出了一种仅用Matlab软件进行快速优化设计的方法。该方法将成像设计中的序列光线追迹原理应用于照明设计中,并利用菲涅尔公式与照度补偿理论,提高了照度拟合速度。同时,通过该方法可将光线追迹与反馈优化紧密相连,实现对照明系统的一站式优化设计。以一紧凑型(h/d=2.5:1)匀光透镜设计为例进行试验,结果表明:给定光源和目标面的参数后,获得匀光透镜数值解的优化时间仅为8 min,优化时间缩短近一个数量级;经SolidWorks成型和TracePro仿真测试,目标面上的均匀度和光效分别达到86.75%和88.42%,照明效果提高明显。
    Abstract: In order to solve the problems of tedious data transmission among multi-software and slow optimization in designing the lens for uniformity with extended sources,according to the sequential ray tracing, Fresnel formula and luminance compensation, we proposed a rapid optimization method by using only one software, Matlab. The method can closely combine ray tracing, illumination fitting and feedback optimization.What is more, we can optimize the lighting system fast and accurately. In order to verify the feasibility of the system, we designed a compact uniform lens of which the h/d is equal to 2.5:1. The results show after giving parameters of the source and target plane, the system optimization time is only 8 min;the uniformity and efficiency in the target plane significantly improve by 86.75% and 88.42%,respectively.
