摘　　要：随着大功率LED光源和照明技术的发展,LED已经广泛的应用于照明领域,这也给灯具的配光设计带来了新的挑战。本文从LED光源应用于道路照明的实际要求出发,对LED路灯的光学系统和灯具的配光要求进行了研究,设计出了一种混合型反射罩光学结构,同时调整每列光源的偏转角度,并通过光学仿真软件进行了仿真,从而达到路灯照明所要求的均匀矩形配光。With the development of the high power LED lighting and the lighting technique, LEDs （Light Emitting Diode） have been applied widely in illumination fields, which brought in new challenges. This article, based on the actual requirements of LED＇s application in street light, makes a research on the optical system of LED street light and its optical requirements and designs a hybrid optical reflector structure. By adjusting the deflection angle of each light source and through simulation with optical simulation software, the designed structure meets the requirement of uniform rectangular light of street light.
