The diffusion of LED lamps for interior lighting, which possess spectral power distributions (SPDs) that considerably differ from the traditional light sources' ones, arose some questions on colour perception, and particularly on colour appearance. These questions led to a debate about the efficacy of CRI and the need of other indexes to evaluate colour quality of lighting sources. An experiment of colour evaluation has been carried out in a test room lit by LED lamps with very high CRI and three different CCTs. Some results were compared to colour attributes derived by applying the CIECAM02 model to measured data.

Abstract
The diffusion of LED lamps for interior lighting, which possess spectral power distributions (SPDs) that considerably differ from the traditional light sources' ones, arose some questions on colour perception, and particularly on colour appearance. These questions led to a debate about the efficacy of CRI and the need of other indexes to evaluate colour quality of lighting sources. An experiment of colour evaluation has been carried out in a test room lit by LED lamps with very high CRI and three different CCTs. Some results were compared to colour attributes derived by applying the CIECAM02 model to measured data.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
