This Part of 61547, which is a Technical Report, establishes an objective method and procedure for testing the immunity performance of lighting equipment against voltage fluctuation disturbances on the a.c. power port.
The object of this Technical Report is to establish a common and objective reference for evaluating the immunity of lighting equipment in terms of illuminance flicker when subjected to mains voltage fluctuations. Temporal changes in the colour of the light (chromatic flicker) are not considered in this test.
This method and procedure can be applied to lighting equipment which is within the scope of IEC technical committee 34, such as lamps and luminaires, intended for connection to a low voltage electricity supply. Independent auxiliaries such as drivers can be tested also by application of a representative light source to that auxiliary.
The method and procedure described in this technical report are based on the
The test method described in this report applies to lighting equipment rated for 230 V a.c. and 50 Hz (for verification purposes).
The principle of the method can be applied for other nominal voltage and frequency ratings.
