通用照明. 发光二极管(LED)产品及相关设备. 术语和定义

[中文适用范围]： “本国际标准 IEC 62504 有助于对与 LED 技术的普通照明相关的术语和定义达成共识。所包含的术语是 IEC LED 标准中已有的或制造商文献中使用的术语。本标准提供了描述性术语 (例如“LED 光源”）以及从 IEC 60050-845 修改后的可测量术语（例如“显色指数”）。注附件 A 概述了 LED 封装设计以及由 LED 光源和控制设备组成的系统。 [外文原描述]： IEC 62504:2014 is of assistance in the common understanding of terms and definitions, relevant for general lighting with LED technology. The terms included are those already available in IEC LED standards or used in manufacturers' literature. This standard provides descriptive terms (like "LED light sources") and measurable terms when modified from IEC 60050-845 (like "colour rendering index"). This first edition cancels and replaces the IEC TS 62504 published in 2011. The significant changes with respect to IEC TS 62504 are as follows: a) Terms from the International Electrotechnical Vocabulary that have not been modified are deleted; b) Alignment with the CIE has been done; c) An introduction has been added.
