This part of IEC 62442 defines measurement and calculation methods for specifying the efficiency and the standby power of controlgear for tungsten-halogen lamps and LED light sources.
NOTE 1 This includes electromagnetic transformers and electronic convertors for tungsten-halogen lamps, as well as electronic controlgear for LED light source(s).
NOTE 2 The term “LED light sources” includes LED modules and LED lamps.
This document is applicable for controlgear designed for use on DC supplies up to 1 000 V and/or AC supplies up to 1 000 V at 50 Hz or 60 Hz.
For multipurpose power supplies only the lighting part will be considered.
NOTE 3 Requirements for testing individual controlgear during production are not included.
This document does not apply to:
– controlgear which form an integral part of lamps (LED light sources);
– controlgear circuits with capacitors connected in series;
– controllable electromagnetic controlgear.
