摘要： A supply assembly for a LED lighting module, comprising a PWM controlled current source supply unit to which the LED lighting module can be connected and a burst control unit which is capable of switching the power supply unit on and off with a burst frequency (fburst) so as to control the mean light output. Preferably, the burst control unit is provided with a pulse duration modulator for controlling the pulse length (T pulse) during which the supply unit is operative.
