摘要：
A high pressure discharge lamp lighting apparatus includes a high pressure discharge lamp and a power supply apparatus, wherein in a steady state lighting operation, an alternating current of a steady state lighting frequency and alternating current of a low frequency are supplied by turns to the high pressure discharge lamp, and wherein in a small electric power lighting in which electric power to be applied is smaller than that of the steady state lighting, alternating current of a small electric power lighting frequency and direct current are supplied by turns to the high pressure discharge lamp.
