Evaluation of LED Sources Based on Colour Appearance Data
The current CIE colour rendering index (CRI) has been widely used to test the quality of light sources over 30 years. However, this method is outdated and problematic, especially for evaluating white light emitting diode (LED) sources. A psychophysical experiment was conducted to evaluate the quality of three D65 simulators. The results were also compared with the CRI and the other method, known as CQS. Furthermore, both indices were modified based on CAM02-UCS, and some improvements were found.
