摘要：

针对贴片LED阵列光源，文中提出了一种新型双层全内反射透镜结构，并利用LightTools -SolidWorks桥对其进行设计与优化,光斑的芯片成像与黄斑问题得到了解决。透镜最大外径为40 mm，透镜总高为12 mm，实现了照明系统的紧凑小型化，实际的软件模拟和测量结果表明，透镜匹配3×3阵列的贴片3030LED光源后，光学效率高达85%以上，光斑均匀，无明显黄斑现象。此款透镜被用于实际射灯灯具中。

Abstract:

A novel LED double-layer TIR(Total Internal Reflection) lens was proposed for the LED source array. And LightTools-SolidWorks bridge was used to design and optimize．The Die-Imaging and Yellow Hue Phenomena of spot was solved．The maximum diameter of the double-layer lens was 40 mm, height was only12 mm, the double-layer lens has advantage of compact and miniaturization. The simulation and experiment results show that the efficiency of the light system were efficiency up to85% While the lens matched with SMD 3030 LED of 3×3 array. Light is soft and uniform and has no obvious Yellow Hue Phenomena．The lens is used for the actual spotlight.

Key words: illumination design, LED source array, double-layer lens, yellow hue phenomena, die imaging
