ABSTRACT:
An arrangement for igniting and operating a high intensity discharge lamp including a Buck converter. The Buck converter includes a switch, a rectifier and an inductor. The converter is connected to input terminals for connection to a supply source and output terminals for supplying the lamp with a current through periodic swithing of the switch alternately into a conducting and a non-conducting state. The Buck converter operates in a self-oscillatory mode during stable lamp opertion. The arrangement further includes circuitry for causing the Buck converter to operate in a forced oscillatory mode in dependence on the lamp condition.
