提升LED日光模拟器同色异谱质量的光谱匹配方法
Spectral Matching Method for Improving Metamerism Quality of LED Daylight Simulator
摘要
Abstract
A spectral matching method for CIE daylight illuminants D50, D55, D65, and D75 was proposed based on the multichannel LED light sources along with the CIE standard for evaluating the spectral quality of a daylight simulator.In view of the fact that it is hard to realize accurate spectral matching, this method can consider spectral matching accuracy as well as metamerism degree simultaneously.The experimental results indicate that the CIE 1976 UCS chromaticity differences of the four matched spectra are less than 0.015 as specified by CIE, and that this method can significantly improve the metamerism index quality grades and the color rendering properties of the matched spectra with comparison to the technique based only on spectral matching accuracy.The quality grades can be improved from the original C or even D grade to the present B level, meanwhile the CIE general color rendering indexes reach up to 98, and the special color rendering indexes R9 are more significantly upgraded to 94 or above.关键词
