摘要
为解决发光二极管(LED)作为朗伯光源难以直接应用的问题,运用非成像光学设计方法,实现了一种新型的基于LED的均匀照明系统,它能够在一个特定位置的屏幕上形成一个具有特定尺寸的均匀圆形光斑。使用基于蒙特卡罗法的光线追迹软件对该光学系统进行模拟仿真,结果显示屏幕上光斑的均匀度优于85%,系统效率高于82%。
Based on nonimaging optics design method, a novel uniform ilhtminance system with LED source was developed. to create a uniform illuminated circular region with desired size in a screen at a prescribed place. By using ray-tracing software based on Monte-Carlo method, the simulation results show that in the illuminated region the luminous uniformity is：better than 85%, and the efficiency of whole system is more than 82%.
