摘要
根据LED光源的特点，定义朗伯光源和近朗伯光源的函数，提出一种LED均匀照明的透镜设计方法。推导出产生均匀光斑的透镜设计方程，采用MATLAB求解该方程的数值解，可实现在目标区域内的均匀照明。
Abstract
According to the characteristics of LED source, Lambertian source function and approximate Lambertian source function were defined, we proposed a method of lens design for LED uniform illumination. We formulated a lens design equation, and with the result of the equation by MATLAB, the uniform illumination at target area was obtained.
