Equipment for general lighting purposes. EMC immunity requirements - An objective light flickermeter and voltage fluctuation immunity test method
1 Scope This part of IEC 61547 describes an objective light flickermeter , which can be applied for, amongst others, the following purposes:
— testing the intrinsic performance of all lighting equipment without voltage fluctuations;
— testing the immunity performance of lighting equipment against (unintentional) voltage fluctuation disturbance on the AC power port;
— testing the immunity performance of lighting equipment against intentional voltage fluctuation on the AC power port arising for example from ripple control systems.
The object of this document is to establish a common and objective reference for evaluating the performance of lighting equipment in terms of illuminance flicker . Temporal changes in the colour of light (chromatic flicker ) are not considered in this test. This method 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 also be tested by application of a representative light source to that auxiliary. The objective light flickermeter and voltage fluctuation immunity method described in this document are based on the IEC 61000‑3��...
