摘要：
The current Colour Rendering Index (CRI) of the CIE (International Commission on Illumination) fails to predict the subjective ranking of the newly introduced lighting sources based on LED (light emitting diode). The aim of this study is to draw a proposal to completing or supplementing the actual and internationally recognised but failing CIE CRI. To acquire a deeper understanding, which would result in more accurate psycho-physical representation of the colour rendition, an extensive review and assessment of the new proposals and the CIE current indices for colour rendering are performed. The assessment is based on an extensive computation of the relevant metrics and calorimetric calculations and on a visual experiment. The subjective experiment uses a real size furnished living room featured with a special diffusing window in the ceiling to change only the spectra of lighting. Preliminary results of this on-going study are given.
