1 Scope

This document specifies the performance requirements for LED modules, as well as the test methods and test conditions for verifying their compliance.

This document applies to the following types of LED modules (see Figure 1).

---Type 1.Integrated type powered by 250V or less DC or 1000V or less 50Hz or 60Hz AC power supply LED modules;

---Type 2.It is driven by a control device connected to the mains voltage and contains internal components that enable it to operate at a constant voltage and constant (Semi-integrated) LED modules with control gear for current or constant power;

---Type 3.All control devices used to control the module to operate in a constant voltage, constant current or constant power state are independent of Module (non-integrated) LED module.

The power supply of the semi-integrated LED module (Type 2) control device is an electronic device that can control the current, voltage or power within the designed range.

The control unit of the semi-integrated LED module (type 2) control gear is the electronic device that controls the power input to the LEDs.

LED modules with external control devices are non-integrated LED modules or semi-integrated LED modules.

Usually, the life of LED modules is longer than the practical test time.

The test time specified in 7.1 is therefore not suitable for verifying the manufacturer's stated lifespan.

This document selects the lumen maintenance code for a specified test time instead of life verification. However, the lumen maintenance code does not represent the predicted value of the actual life time. The category represented by the code is the luminous flux attenuation consistent with the information provided by the manufacturer before the test starts.

The category of the feature.

The pass/fail criteria for life tests specified in this document differ from the life measurement method stated by the manufacturer.

For an explanation of the measurement method, see Appendix A.
