ABSTRACT:
A discharge lamp lighting apparatus for lighting a plurality of discharge lamps comprises: a control circuit adapted to output driving signals; a plurality of step-up transformers; and a plurality of bridge circuits, each of which is connected to a DC power supply, and drives the primary side of each of the step-up transformers according to the driving signals from the control circuit so as to light each of the discharge lamps connected respectively to the secondary sides of the step-up transformers. In the discharge lamp lighting apparatus, each of the bridge circuits is connected to the control circuit via synchronous switching elements, and the synchronous switching elements, according to each of synchronizing signals applied thereto, switch on and off the driving signals from the control circuit so as to controllably cause each of the bridge circuits to start and stop its operation.
