1 Scope
This document specifies general and safety requirements for light-emitting diode (LED) modules.
LED modules within the scope of this document can be integral, built-in or independent:
——non-integrated LED modules (LEDni modules) and semi-integrated LED modules (LEDsi modules) for operation under constant voltage, constant current or constant power;
——Integrated LED modules (LEDi modules) for use on DC supplies up to 250 V or AC supplies up to 1 000 V at 50 Hz or 60 Hz.
This document is not applicable for LED lamps.
Note: The performance requirements for LED modules are specified in IEC 62717.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 62504 and the following apply.
3.1
ultraviolet hazard efficacy of luminous radiation
KS,v
quotient of an ultraviolet hazard quantity to the corresponding photometric quantity
Note 1: Ultraviolet hazard efficacy of luminous radiation is expressed in mW/klm.
Note 2: The ultraviolet hazard efficacy of luminous radiation is obtained by weighting the spectral power distribution of the lamp or LED module with the UV hazard function SUV (λ). Information about the relevant UV hazard function is given in IEC 62471:2006. It only relates to possible hazards regarding UV exposure of human beings. It does not deal with the possible influence of optical radiation on materials, such as mechanical damage or discoloration.
3.2
replaceable LED module
LED module, designed to be replaced by an ordinary person or a qualified person
Note: When incorporated into a luminaire, a replaceable LED module can be classified as replaceable, non-user replaceable or non-replaceable depending on the luminaire design.
3.3
non-replaceable LED module
LED module designed to be a non-replaceable part of the luminaire
Note 1: An integral LED module is always non-replaceable. A non-replaceable LED module is not always an integral LED module.
Note 2: The non-replaceability can be the result of the luminaire design.
3.4
non-user replaceable LED module
LED module designed to be replaced only by the manufacturer, his service agent, or similar qualified person
Note: When incorporated into a luminaire a non-user replaceable LED module can become classified as non-replaceable depending on the luminaire design.
3.5
terminal
conductive part of an LED module, provided for connecting that LED module to one or more external conductors
[SOURCE: GB/T 2900.83-2008, 151-12-12, modified]
3.6
integral terminal
terminal (3.5) which forms a non-replaceable part of an LED module and which cannot be tested separately from the LED module
[SOURCE: GB/T 7000.1-2023, 1.2.58, modified]
4 General requirements
4.1 LED modules shall be so designed and constructed that they operate without danger to the user or surroundings when used as intended (see manufacturer’s instructions).
NOTE: GB/T 19510.1-2023, Annex S gives examples of insulation coordination which can be appropriate for LED modules.
4.2 LED modules shall be classified, according to the method of installation, as:
——built-in,
——independent, or
——integral.
4.3 For non-integrated LED modules and semi-integrated LED modules, all electrical measurements, unless otherwise specified, shall be carried out at voltage limits (min/max), current limits (min/max) or power limits (min/max) and minimum frequency, in a draught-free room at the temperature limits of the allowed range specified by the manufacturer. Unless the manufacturer indicates the most critical combination, all combinations (min/max) of voltage/current/power and temperature shall be tested.
4.4 For integrated LED modules, the electrical measurements shall be carried out at the tolerance limit values of the rated supply voltage.
4.5 Integral LED modules not having their own enclosure shall be regarded as integral components of luminaires according to GB/T 7000.1-2023, 0.5.1.
4.6 In addition to the requirements of this document, independent LED modules shall comply with GB/T 7000.1-2023.
4.7 If the LED module is a factory sealed unit, it shall not be opened for any tests. In case of doubt based on the inspection of the LED module and the examination of the circuit diagram, and in agreement with the manufacturer or responsible vendor, such specially prepared LED modules shall be submitted for testing so that a fault condition can be simulated.
4.8 For LED modules with integrated controlgear providing SELV, the requirements according to GB/T 7000.1-2023, Clauses L.5, L.6, L.7, L.8, L.9, L.10, and L.11 apply.
5 General test requirements
5.1 Tests according to this document shall be type tests.
Note: The requirements and tolerances in this document are related to testing of a type-test sample submitted by the manufacturer for that purpose.
Conformity of production is the responsibility of the manufacturer and can need routine tests and quality assurance in addition to type testing.
5.2 The test shall be carried out at an ambient temperature of 10 °C to 30 °C. If the manufacturer specifies a different ambient termperature, this shall be used as test temperature.
5.3 Unless otherwise specified, the type test shall be carried out on one sample consisting of one or more items submitted for the purpose of the type test.
In general, all tests shall be carried out on each type of LED module or, where a range of similar LED modules is involved, for each power in the range or on a representative selection from the range, as agreed with the manufacturer.
5.4 If the light output has substantially changed, the LED module shall not be used for further tests.
Note: Usually, a value of 50 % indicates irreversible changes in the LED module.
5.5 Testing of integral LED modules not having their own enclosure shall be done as part of the luminaire as far as applicable.
