摘要

光学仿真是白光LED照明设计中的一个重要方法

但色度分布的光学仿真中计算量太过庞大

以致在一般计算条件下无法得到可靠的仿真结果。为解决这一问题

本文利用色度转换关系和逐点法计算色温

引入数值拟合和像素合成两种处理方法

有效降低了光学仿真结果的涨落。通过对处理结果和实验结果在照度和相关色温两方面的对比

两种处理方法的有效性得到证明

大幅提升了基于色度配光的光学仿真计算效率。

Abstract

The optical simulation is an important method for white LED illumination design

but it is too heavy of computation to get some reliable results in a color distribution simulation by using an ordinary computer. To reduce the amount of calculation

the chromatic relations and the point-to-point method are employed

as well as the numerical fitting method and pixels synthesis are introduced to decrease the fluctuation of correlated color temperature of optical simulation results. The validity of the above two methods is demonstrated by comparing with the experimental results

and the performance of color simulations is improved greatly.
