运用非成像光学理论,基于LED能量网格划分的方法设计了一种全偏光的LED隧道灯透镜。该设计方法不仅具有传统偏光透镜中能量利用率高的优点,并且在保持高亮度均匀度的前提下,能有效地降低道路照明中眩目的影响。在照明分析软件DIALux中验证了该透镜,其配光曲线实现了UE =0.88, UO =0.86, UL =0.91, TI=6的良好照明效果。

A totally asymmetric design method for LED tunnel light lens is proposed , which is based on the mesh grids division of the LED light source with the theory of nonimaging optics .This method can not only have high energy utilization efficiency as the traditional lens , but also effectively reduce the glare effect for drivers while keeping in high uniformity of road surface luminance .A lighting simulation is made for the light distributions curve of the lens with DIALux , and it shows an excellent result with UE =0.88, UO =0.86, UI =0.91, TI=6.
