Abstract

Abstract

In the past two decades, incandescent lamps and gas-discharge light sources were gradually replaced by LEDs. The significant differences in the optical characteristics of LEDs and traditional incandescent light sources have introduced metrological challenges. There has been a revolutionary change from incandescent-based techniques to LED-based ones in the field of radiometry and photometry since 1909. This paper introduces the activities being carried out within the Consultative Committee for Photometry and Radiometry (CCPR) and the Commission Internationale de l´Eclairage (CIE) to address LED metrology issues, including information on the strategic plan for this emerging area, development of LED comparison artifacts, establishment of new white LED-based CIE standard illuminants for photometry, and the features and metrological characteristics of two LED standards developed by the National Institute of Metrology (NIM), China. Finally, the prospect of development and application of LED standard artifacts in the future is provided.
