本标准规定了驱动器、辅助电源、控制器、传感器、安装在灯具上的控制设备以及支持设备间数字接口的通信设备等设备的最低要求。本标准以IEC 62386系列标准中规定的数字可寻址照明接口为基础，规定了内存库使用、逻辑信号接口、能量报告、诊断信息的要求，以及可能集成到LED驱动器中的辅助电源的要求。

This standard specifies the minimum requirements for devices such as drivers, AUX power supplies, controls, sensors, luminaire mounted control devices, and communication devices supporting a digital interface between devices.This standard builds on the digital addressable lighting interface as specified in the IEC 62386 series of standards to specify the requirements for memory bank usage, logic signal interface, energy reporting, diagnostic information, as well as requirements for auxiliary power supplies that may be integrated into an LED driver.
