A few days ago, the SSL Ecosystem Summit 2014 was successfully concluded.
According to foreign media reports, industry experts attending the summit pointed out that the color rendering index (CRI) is commonly used to define the color quality of LED lamps, but it is not perfect in terms of color perception measurement and will soon be replaced by other color measurement standards. .
Terry McGowan, Technical Director of the American Lighting Association (ALA) pointed out that CRI is not enough to represent color perception. He said that as early as August, the Lighting Engineering Society (IES) had proposed to the government to stop using CRI to define energy regulations. CRI is likely to be replaced and replaced by a combination of the Color Quality Standard (CGS) and the Gamut Area Index (GAI).
Director, Lighting Research Center, Rensselaer Polytechnic Institute. Nanrandran said that the university’s LRC ASSIST Program is combining CGS and GAI and will soon replace CRI.
