Leading edge dimming
Trailing edge dimming
Light dimming is realized with “phase cutting technology”, which works by “cutting off” part of the mains voltage waveform in order to reduce the
RMS voltage fed to the lamp. If such “cutting off” is done at the beginning of the sine wave, the dimming method is called Leading Edge, if it is done
towards the end it is called Trailing Edge. These 2 methods are suitable for dimming different lamp types: Trailing Edge is, in general, more suitable
for electronic transformers for low voltage lamps (halogen or LED). Leading Edge is better suited for electromagnetic transformers for LV lamps, 230 V
CFL and 230 V Led lamps. Both methods are, however, suitable for dimming 230 V halogen and incandescent lamps.
In consideration of the different lamp types actually available on the market, it is suggested to refer to the technical specification indicated in page 1
and, if given, to the lamp manufacturer’s recommendation.
