IS 16107 : Part 2/Sec 1 : 2012 : Luminaires performance Part 2 Particular requirements Section 1 LED Luminaire

1. Scope

1.1 This standard (Part 2/Sec 1) specifies the performance requirements for LED luminaires, together with the test methods and conditions, required to show compliance with this standard. It applies to LED luminaires for general lighting purposes, where claims of operational performance are made.

The following types of LED luminaires are distinguished:

a) Type A - Luminaire using LED modules that have not been shown to comply with IS 16103 (Part 2) : 2012 ‘LED modules for general lighting: Part 2 Performance requirements’;

b) Type B - Luminaire using LED modules that have been shown to comply with IS 16103 (Part 2); and

c) Type C - Luminaire using a LED lamp and covered in IS 16107 (Part 1) : 2012 ‘Luminaires performance: Part 1 General requirements’.

NOTE The definition of the LED module is given in

IS 16101 : 2012 ‘General lighting — LEDs and LED modules - Terms and definitions’.

This standard does not cover LED luminaires that intentionally produce coloured light; neither does it cover modules based on OLEDs (organic LEDs).

The performance requirements are additional to the requirements given in IS 16107 (Part 1).

As this standard has been simultaneously developed with the standard for LED modules, where appropriate, the compliance of the modules to the provisions of IS 16103 (Part 2) 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 percent of rated life (with a maximum of 6 000 h), is out of the scope of this standard.

Instead of life time validation, this standard 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 acceptance or rejection criterion of the life time test as defined in this standard is different from the life time metrics claimed by manufacturers. Explanation of recommended life time metrics is given in Annex B of IS 16103 (Part 2).

The performance requirements specified in this standard are additional to the safety requirements given in IS 10322 (Part 1).

1.2 It may be expected that LED luminaires which comply with this standard shall start and operate satisfactorily at voltages between 90 and 110 percent of rated supply voltage and at an ambient air temperature within the declared range of the manufacturer.

1.3 Testing of principle components is not within the scope of this standard.
