| 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. |
