摘　　要： 概括了LED在照明领域中的应用,根据光度学原理和LED发光特性在CAD软件中建模了三维多圆环LED阵列,实现了均匀发光的球面光源并建模了旋转圆锥反射灯罩模型.导入TracePro中进行光线追迹,得到照度分布图,符合照明要求.该设计结构简单,节省了设计时间与制造成本. The application of LED in illumination is generalized.LED array with multiple circles with three-dimensions,based on the photometric principle and the luminous characteristic of LED,is modeled in CAD software,A spherical surface with the characteristic of uniform illumination as a light source is achieved,and the model of the reflection with the figure of revolving cone is obtained,which is imported to TracePro to execute ray tracing to get the chart of illuminance conforming to the standard of illumination.The structure of designing is simple to save the time of design and the cost of manufacture.
