ABSTRACT:
In at least one embodiment of the disclosure a discharge lamp lighting apparatus includes a controller configured to control an AC conversion circuit to perform AC conversion control for controlling the timings at which a polarity of the discharge lamp driving AC current is reversed. The controller is configured to control the power control circuit to perform current control for controlling a magnitude of the DC current. The controller changes the accumulated energy supplied to each electrode of a discharge lamp in one cycle of the discharge lamp driving AC current in accordance with a periodic pattern. The periodic pattern includes a plurality of segmented periods during each of which the accumulated energy is maintained at a same level for a plurality of cycles of the discharge lamp driving AC current, and a level of the accumulated energy in at least two of the segmented periods differ from each other.
