Abstract

The CIE colour rendering index (CRI) has been used to test the colour rendering properties of light sources for over 30 years. However, this method is outdated and problematic, especially for evaluating white light emitting diodes (LEDs) [1]. In present work, the current CIE Test Method has been investigated by comparing visual colour rendering of test samples between LED light sources and a reference fluorescent lamp. The results show that CIE CRI is not good enough to predict visual perception. Moreover, the method was modified based on CAM02-UCS [2], and it provided better correlation between visual and predicted colour rendering values.
