This standard specifies the performance requirements of LED modules for general lighting, as well as the test methods and conditions for verifying their compliance. LED modules can be divided into the following types, as shown in Figure 1: Type 1: Integrated LED modules powered by 250 V and below DC or 1000 V and below 50 Hz or 60 Hz AC power supply. Type 2: A (semi integrated) LED module that is connected to the power supply voltage through an independent control device and contains a control device that operates at a constant voltage, constant current, or constant power. Type 3: LED module used to control all control devices operating under constant voltage, constant current, or constant power conditions, which are independent of the module (non integrated)
