摘要
LED平面光源是LED应用于照明领域的新型封装产品,文中针对LED路灯配光成本过高问题,提出了一种将灯壳的防护、散热功能和配光结合在一起,几乎不增加成本的LED平面光源路灯的配光方案,给出了对应的路面照度的计算方法,并结合实例利用excel的宏调用功能模拟计算道路的照明效果。应用这些方法,可以在给定道路和布杆情况下模拟确定最适宜灯具的参数,同时也可以为道路照明设计提供参考。
LED flat light source is a new package for lighting applications.To resolve The LED street lantern light distribution high cost problem,this paper puts forward a light distribution method of street lamp that used LED flat light source,which puts the shell protection,cooling and light distribution function together,almost no increase additional costs.This paper also presents the calculation method of the road surface illuminance,and the example illustrate how to use excel macro calls function simulation road lighting effect.By application of these methods in a given road and light pole layout situation to the most appropriate parameters of the lanterns can be,determine at the same time it can provide reference for road lighting design.
