The control unit carries out repair control to change, in a first cyclical pattern, cumulative energy supplied to each electrode of a discharge lamp during one cycle of the AC current for discharge lamp driving, in predetermined timing. The first cyclical pattern includes plural sectional periods in which the cumulative energy is maintained at the same value over plural cycles of the AC current for discharge lamp driving.
