Description / Abstract:

This Part of 61547, which is a Technical Report, 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 a.c. power port; – Testing the immunity performance of lighting equipment against intentional voltage fluctuation on the a.c. power port arising e.g. from ripple control systems. The object of this Technical Report 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 the 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 be tested also by application of a representative light source to that auxiliary. The objective light flickermeter and voltage fluctuation immunity method described in this technical report are based on the IEC 61000-3-3 standard for voltage fluctuation limits and the flickermeter standard IEC 61000-4-15. The objective light flickermeter described in this report can be applied to objectively assess flicker of lighting equipment that is powered from any type of source, a.c. mains, d.c. mains, battery fed or fed through an external dimmer. The specific voltage fluctuation immunity test method described in this report applies to lighting equipment rated for 120 V a.c. and 230 V a.c., 50 Hz and 60 Hz. NOTE – The principle of the method can be applied for other nominal voltage and frequency ratings.
