ABSTRACT:
A HID lamp light source device in which the disadvantage of acoustic resonance is avoided is achieved in a light source device in which a discharge lamp has a pair of opposed electrodes connected to a feed device which is used for starting the discharge lamp and for supplying a discharge current to the electrodes by the feed device using a switching device for controlling the amount of feed for the discharge lamp and in which phase modulation is added to the essentially periodic switching operation of the switching device.
