IEC 63013:2017+A1:2021适用于一般照明服务的LED组件。它规定了测量LED封装光通量的程序和条件。它还提供了基于收集的有限光通量维护测试数据预测长期光通量维护的程序和条件（标准）。在本文件的上下文中，如果规定了光通量测量数据，也可以使用辐射通量测量数据。

IEC 63013:2017+A1:2021 is applicable to LED packages for general lighting services. It specifies procedures and conditions for measuring the luminous flux maintenance of LED packages. It also provides the procedures and conditions (criteria) of projecting the long-term luminous flux maintenance based on limited luminous flux maintenance test data collected. Within the context of this document, wherever luminous flux measurement data is specified, radiant flux measurement data can also be used.
