Status and Demand Analysis of LED Standard Lamps

  • 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。
