摘要：
Improved method and device for lighting a high pressure discharge lamp are provided which prevent arc jump and inhibit deterioration of lamp voltage and luminance. The method includes the step of: alternately repeating a superposition operation for superposing a pulse current on a lamp current applied to the high pressure discharge lamp for a predetermined time period and a superposition stopping operation for stopping the superposition of the pulse current for a predetermined time period.
