摘要
本文利用Trace Pro光学设计软件模拟LED路灯两种不同配光方案的光学设计效果,将Trace Pro仿真结果导入至Dialux软件中,模拟两种不同配光方案的实际道路照明效果,并进行比较分析。分析Trace Pro和Dialux所得结果可知,采用花生壳透镜进行一次配光设计的LED路灯设计与花生壳透镜作为二次透镜进行二次配光的LED路灯设计,均能获得蝙蝠翼型配光曲线,进而获得道路照明所需的矩形光场;但是通过Dialux软件模拟两种配光方案的实际道路照明效果发现花生壳透镜作为二次透镜进行二次配光的LED路灯的均匀性更佳,在实际道路照明中更可取。
Two different models of LED streetlight are constructed and simulated by Trace Pro.Importing the data of Trace Pro in Dialux, practical simulation of the road lighting is analyzed and compared. From results of simulation, it is found that both of the first optics design of a peanut form lens and the secondary optics design of peanut form lens can achieve light distribution curve of bat wing and rectangular light field; but the uniformity of the second model, i.e. the secondary optics design of peanut form lens is better, and that is more suitable for practical road lighting.
