Abstract

CIE D50 and A simulators based on a multi-channel LED system were evaluated and compared with those based on conventional fluorescent and tungsten sources. A psychophysical experiment was carried out for critically evaluating the colour difference of 30 metameric pairs. The results showed that LED lighting based on 9 channels can successfully achieve the desired quality specified by ISO 3664:2008(E) viewing conditions for the applications of graphic technology and photography. In the visual experiment, it was found that LED simulator outperformed the conventional fluorescent simulator under D50 illuminant, and gave similar performance as the tungsten simulator under A illuminant.
