摘要

在含有多个LED排列的光源中

需要对RGB LED照明单元的排列组合进行精确的设计。文章将每一个单色LED看成是一个非理想的朗伯发射体

分析了LED排列的几种典型结构

根据设计方程式模拟出了不同LED结构的照度分布情况。模拟结果表明

排列LED在其极值范围内可以得到比较均匀的照度分布

随着LED之间距离的增大

其中心位置的照度随之下降; 增大LED阵列中心到被照平面的距离

照度均匀性也随之逐渐降低。

Abstract

Due to different situations requiring different uniform irradiance distribution

light sources with multiple LEDs become the preferred choice. So designing LED arrays for uniform irradiance is an essential problem. According to analyzing several typical configurations of LED illumination modules

the equations and formulas were established and the limit distance between LEDs was simulated with considering each single LED as a nonideal Lambertian emitter. From the result of simulation we can get the uniform irradiance in the distance of LEDs limit situation. Luminous intensity of center placement would abate

while the distance of LED increases; the increasing distance between the LED arrays center and the irradiance plane leads to the slacking down of the center irradiance.
