Performance specification of LED modules for general lighting
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.
Figure 1 LED module types
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.

General lighting LED module performance requirements
1 Scope
1.1 Overview
This standard specifies the performance requirements of LED modules, as well as test its compliance with the test methods and test conditions. LED module distinction
For the following types, see Figure 1.
Type 1. Integrated LED powered by 250V DC or below or 1000V and below 50Hz or 60Hz AC power
Module.
Type 2. The supply voltage is connected to the mains voltage via an independent control device and internally contains a voltage that allows it to operate at a constant voltage, constant current
Or semi-integrated LED modules for control devices at constant power.
Type 3. All controls for the control module operating at constant voltage, constant current, or constant power are independent of the module
(Non-integrated) LED module.
Semi-Integrated LED Module (Type 2) The control unit's power supply is an electronic device that can control current, voltage or power within the design range.
Semi-Integrated LED Module (Type 2) The control unit of the control unit is an electronic device that controls the power input to the LEDs.
LED modules with external controls are either non-integrated LED modules or semi-integrated LED modules.
Figure 1 LED module type
The requirements of this standard only applies to type testing.
Methods for full product inspection or batch inspection are under study.
This standard covers the LED module, based on white LED inorganic light technology.
LED modules typically have longer lifetimes than are practicable in practice. Because the test data in time to make further projections of the party
The law is not standardized, so producers can not be validated for their life expectancy in a sufficiently credible way. Therefore, the test time specified in 6.1
To verify the producer's claimed life, does not belong to the scope of this standard.
This standard specifies the test of the lumen maintenance rate code to replace the life-time verification. However, the lumen maintenance code does not imply right
