This PAS specifies the performance requirements for LED luminaires@ together with the test methods and conditions@ required to show compliance with this PAS. It applies to LED luminaires for general lighting purposes@ where claims of operational performance are made. The following types of LED luminaires are distinguished: ?C Type A ?C Luminaires using LED modules that have not been shown to comply with IEC/PAS 62717; ?C Type B ?C Luminaires using LED modules that have been shown to comply with IEC/PAS 62717; ?C Type C ?C Luminaires using a LED lamp and covered in IEC/PAS 62722-1. NOTE The definition of the LED module is given in IEC/TS 62504. The requirements of this PAS only relate to type testing. This PAS does not cover LED luminaires that intentionally produce coloured light; neither does it cover luminaires using OLEDs (organic LEDs). These performance requirements are additional to the requirements in IEC/PAS 62722-1. As this PAS has been simultaneously developed and edited with the PAS for LED modules@ where appropriate the compliance of the modules to the provisions of IEC/PAS 62717 may be transferred to the whole luminaire. Life time of LED luminaires is in most cases much longer than the practical test times. Consequently@ verification of manufacturer's life time claims cannot be made in a sufficiently confident way. For that reason the acceptance or rejection of a manufacturer's life time claim@ past 25 % of rated life (with a maximum of 6 000 h)@ is out of the scope of this PAS. Instead of life time validation this PAS has opted for lumen maintenance categories at a defined finite test time. Therefore@ the category number does not imply a prediction of achievable life time. The categories are lumen-depreciation character categories showing behaviour in agreement with manufacturer's information which is provided before the test is started. In order to validate a life time claim@ an extrapolation of test data is needed. A general method of projecting measurement data beyond limited test time is under consideration. The pass/fail criterion of the life time test as defined in this PAS is different from the life time metrics claimed by manufacturers. For explanation of recommended life time metrics see IEC/PAS 62717@ Annex C. It may be expected that LED luminaires which comply with this PAS will start and operate satisfactorily at voltages between 92 % and 106 % of rated supply voltage and at an ambient air temperature within the declared range of the manufacturer. The requirements of this PAS apply in addition to the IEC/PAS 62722-1.
