摘要

In this study, the performance of the CIE-CRI for three low energy light sources which are present in Iran's markets has been investigated. The light sources included a halogen and two white LED lamps. In addition, a daylight simulator produced by Thorn Lighting Ltd was used as a reference source. The visual experiment was performed using 14 Munsell samples proposed by the CIE to compute the CIE Ri. The results of the first 8 samples used for calculating Ra showed that using CIECAT02 chromatic adaptation transform instead of Von Kries can improve the performance of the CRI. In addition, computing color difference in CIELAB color space gave more acceptable results in comparison with CIE1964U*V*W*. However, using more developed color difference formulae such as CMC or CIEDE00 had no significant improvement. Furthermore, applying CAM02-UCS can give the best correlation with visual results.
