摘要

摘要: 针对现有发光二极管(LED)汽车后转向灯存在的配光性能不准确、能量利用率低等问题,设计了一款准直配光一体化的LED后转向灯透镜。该透镜根据非成像光学原理和斯涅尔定理,通过迭代求解的方法设计而成,其高度为8.32 mm,直径为12.64 mm。利用光学软件TracePro对实际光源和后转向灯透镜进行光线追迹模拟,结果表明:在x方向80,y方向80的矩形区间,发光强度均大于1.6 cd;在x方向20,y方向10内发光强度呈近似矩形分布,且各测试点结果均满足GB17905-2008要求。该透镜可精确控制LED发出光线,有利于提高配光性能及能量利用率。

Abstract: A lens for a Light Emitting Diode (LED) rear turn lamp of motor vehicles is designed to increase the accuracy of light distribution and energy efficiency of the lamp. According to the nonimaging optical principle and Snell's law, the lens design is obtained by an iterative solution, and the height and the diameter of the lens are 8.32 mm and 12.64 mm, respectively. By using the optical software TracePro, the LED and the lens of rear turn lamp are traced and simulated. The results show that in a rectangular range from -80? to 80? in the x direction and from -80? to 80? in the y direction, the luminous intensity is greater than 1.6 cd. Moreover, in the rectangular range from -20皌o 20癷n the x direction and from -10皌o 10癷n the y direction, the luminous intensity distribution is approximatly rectangular, and the luminous intensity of each test point meets the requirements of GB17905-2008. The lens can control the LED light precisely, which is beneficial to improve the performance of the light distribution and energy efficiency of the rear turn lamp.
