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 IEC 61347-1:2015, 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 (mm/max), current limits (mm/max) or power limits (mm/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 (mm/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 IEC 60598-1:2014, 0.5.1.
4.6 In addition to the requirements of this document, independent LED modules shall comply with IEC 60598-1:2014 and IEC 60598-1:2014/AMD1:2017.
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 IEC 61347-1:2015 and IEC 61 347-1 :2015/AMD1 :2017, 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.
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.
