Status and Demand Analysis of LED Standard Lamps

National Institute of Metrology, Beijing 100029, China

摘要

摘要: 近二十年来，LED灯逐渐替代白炽灯和多种气体放电光源，成为主要的照明光源。LED灯的发光特性与白炽灯有明显差异，带来了新的计量挑战，LED灯的测量成为光辐射测量领域重点关注的方向。建立基于LED 灯的量值传递体系，用LED 标准灯代替白炽标准灯，是光度计量史上自1909年以来的重要变革。本文介绍了CCPR和CIE 在LED 计量领域的战略规划和相关工作，包括LED作为传递标准的国际比对的进展，CIE 新的LED 参考照明体的制订以及中国计量科学研究院研制的两种LED 标准灯的特点和计量特性。最后对LED 标准灯的未来发展和应用进行了分析和展望。

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.
