摘要

摘要:设计了一组合式路灯反射器,以使发光二极管(LED)路灯在道路照明时产生矩形光斑和均匀照度。在非成像光学基础上,利用复合抛物面的高性能集光作用和机械设计软件的强大作图功能,设计了一款分段组合复合抛物面反射器(CPC)。基于边缘光线原理和裁剪法,此款反射器能将朗伯型发光的LED光束整形为近似矩形分布,出光效率达96%以上。理论模拟证明:在高度为10 m,范围为10 m30 m内利用此反射器进行二次配光的LED路灯的照度均匀度达0.5以上。该反射式LED路灯光束整形器结构简单,光学效率高、成本低廉,模拟结果完全达到了目前我国国家道路照明规范要求。

Abstract:A combined reflector for Light Emitting Diode(LED) street lamps is designed to produce a rectangular light spot and uniform lighting in the road, as well as having a simple structure and high light efficiency. Based on the principles of non-imaging optics and mechanical design software, a segmented compound parabolic reflector was designed. The reflecting beams of light from the reflector have an approximately rectangular distribution while the light efficiency can reach 96%. The analysis and simulation results show that the uniformity of illuminance can reach 0.5 over an area of 10 m?30 m when the LED lamp is installed at a height of 10 m. The reflector design when applied to shaping the LED beam into the rectangle shape has a high optical efficiency and low costs. The simulation results show that it can satisfy the current requirement for road lighting.
