摘要

从实测的LED光谱分布出发

对基于LED光谱可调光源进行了可行性验证。提出用非对称高斯分布函数的数学模型来拟合单个LED光谱分布

并以该数学模型为基础

运用多种不同峰值波长的LED来合成所需要的光谱分布。在原理上实现了对任意目标光谱的最小二乘拟合

使用不同峰值波长的单色LED分别对D65、溴钨灯、5500K理想黑体、日光照射下的标准白板的光谱分布进行拟合

相关指数均在0.94以上。最后通过对数据的分析

总结出在工程实践中必须注意的要点。

Abstract

The feasibility of spectral tunable LED-based light source was verified. The source is capable of producing any spectral distribution. According to the measured LED spectral distribution

an asymmetric Gaussian function model was proposed to fit the individual LED spectral distribution. A variety of different LEDs with different peak wavelengths were utilized to synthesize the required spectral distribution. In theory

the least square fitting for any spectrum is realized. The experimental results of synthesis of typical spectral distribution are satisfactory. Finally

based on the analysis of experimental data

this paper put forward some points for the engineering practice.
