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Light Tools-Solid Works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。A novel LED double-layer TIR（Total Internal Reflection） lens was proposed for the LED source array. And Light Tools-Solid Works 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.
