摘要

采用逆向优化设计的方法设计发光二极管(LED)路灯透镜,提高LED 路灯道路照明质量和能量利用率。以城市道路照明标准为约束,优化出最大亮度照度比的理想配光曲线。基于得到的理想配光曲线,透镜采用分离变量法设计自由曲面,将光源和目标面进行网格划分,形成能量对映关系。同时对曲面构造误差进行控制,再利用反馈优化法对透镜进行优化,使透镜的配光曲线趋于理想。仿真实验表明:采用逆向优化设计的LED 路灯透镜,能很好地符合道路照明标准,亮度照度比为0.067,同时相对于传统的对称型LED 路灯配光曲线节省20.2% 的能耗,使LED 路灯达到了高照明质量和高能量利用率的目的。

Abstract

To improve the quality and energy efficiency of road lighting, the reverse optimization design method is employed to design a light-emitting diode (LED) street lamp lens. By taking the road lighting standard as constraint, an ideal light intensity distribution with maximum brightness illumination ratio is optimized and obtained. Based on the optimized ideal light intensity distribution, the freeform surface is established by using the variable separation mapping method. The light source and target plane are meshed to form the mapping relationship, and the surface structure error is controlled as well. Then the lens is optimized by using feedback optimization to make the intensity distribution of lens close to ideal light intensity distribution. Simulation experiment results show that the lens designed by the proposed method conforms to the road lighting standard well, and the brightness illumination ratio is 0.067. Compared with traditional symmetry light intensity distribution, energy consumption is reduced to 20.2% . The high quality lighting and energy utilization ratio of LED street lamp are realized finally.
