摘　　要：本文提出了一种用于形成均匀照度环形光斑的LED路灯自由曲面的设计方案,以满足LED路灯在环形交叉口路段的照明要求。介绍了设计流程,给出了构造所需自由曲面的基本思路和设计方法。基于该方法,给出了一个透镜设计的实例,并对该光学系统进行了模拟仿真,结果验证了该方法的可行性。This paper presents a method for forming an annulus uniform illumination with the design of free form surfaces to meet the lighting requirements of LED on roundabouts sections. The design process was introduced. The basic idea and design method shaping the required free-form surface were presented. Based on the method, an example of len design was presented, and simulation of this optical system was undertaken. The result verified the feasibility of the method.
