IEC 62717-2019 pdf free.LED modules for general lighting – Performance requirements.
Life time of LED modules is in most cases much longer than the practical test times.Consequently,verification of manufacturer’s life time claims cannot be made in a sufficientlyconfident way, because projecting test data further in time is not standardised. For thatreason the acceptance or rejection of a manufacturers life time claim, past an operational timeas stated in 6.1, is out of the scope of this standard.
Instead of life time validation this standard has opted for lumen maintenance codes at adefined finite test time.Therefore, the code number does not imply a prediction of achievablelife time. The categories,represented by the code, are lumen-depreciation charactercategories showing behaviour in agreement with manufacturer’s information which is providedbefore the test is started.
In order to validate a life time claim, an extrapolation of test data is needed. A general methodof projecting measurement data beyond limited test time is under consideration.
The pass/fail criterion of the life time test as defined in this standard is different from the lifetime metrics claimed by manufacturers. For explanation of recommended life time metrics,see Annex C.
NOTE When modules are operated in a luminaire,the claimed performance data can deviate from the valuesestablished via this standard due to e.g. luminaire components that impact the performance of the LED module.The separate electronic controlgear for LED modules as mentioned in Type 2 and Type 3 isnot part of the testing against the requirements of this standard.
Protection for water and dust ingress, see B.3.
lt may be expected that integrated LED modules which comply with this standard will start andoperate satisfactorily at voltages between 92 % and 106 % of rated supply voltage. LEDmodules with separate controlgear are expected to start and operate satisfactorily incombination with the specified controlgear complying with lEC 61347-2-13 and lEC 62384.AllLED modules are expected to start and operate satisfactorily when operated under theconditions specified by the LED module manufacturer and in a luminaire complying withIEC 60598-1.
The requirements for individuals apply for 95 % of the population.
