Activities of Interbation Standanzation for Color Rendering Specification of LED Light Sources(<Special Issue>Towards Standardization of LED Lighting-Direction of Japan's Strategy for Globalization)

Abstract

As the CIE Color Rendering Method (CIE Pub.13.3-1995) can apply only to fluorescent lamps, the color rendering indices of LED light sources cannot be calculated on the definition of the CIE color rendering specification. CIE TC1-69 was established to investigate new methods for assessing the color rendition properties of white-light sources used for illumination including solid-state light sources, with the goal of recommending new assessment procedures. This paper outlined the activities of TC1-69 and of the domestic Technical Committee of JCIE (Japanese National Committee of the CIE) corresponding to TC1-69.
