为适应半导体产业的迅猛发展和环保节能的迫切要求,将LED作为一种新的能源方式应用到照明产业中.选取几种有代表性的LED路灯作为研究对象,根据各自不同形状的配光曲线,利用照明仿真软件Dialux对这些LED灯具在不同的布灯方式下在道路上的光照度分布情况进行模拟和分析比较,总结出适合于道路照明的LED路灯应具有的配光曲线特征,为LED灯具设计提供参考.%With the dramatic development of semiconductor industry and the pressing need of environment protection, LED has acted as a new energy source to be applied to lighting industry. This paper selected several typical kinds of LED street lamps as the research objects which have different shapes in their respective light distribution curves. By using the light designing software Dialux, this paper simulated the LED street lamps' illuminance distribution on the road and made an analytic comparison between two different street lamps' array methods, then summed up the features of LED's light distribution curve which were suitable for roadway lighting to provide reference for the design of LED luminaries.
