In the first control and the second control, the absolute value of a drive current is relatively small in a first period and relatively large in a second period. In the first control, the energy provided to a first electrode in the second period is greater than the energy provided to the second electrode in the second period. In the second control, the energy provided to the second electrode in the second period is greater than the energy provided to the first electrode in the second period.

摘要： According to an aspect of the invention, a discharge lamp driving device includes a discharge lamp driving section, a control section, and a voltage detecting section. The control section is configured to execute a first discharge lamp driving for executing a first control and a second control for supplying a driving current including a direct current and an alternating current to a discharge lamp. In the first discharge lamp driving, the control section executes the first control when the interelectrode voltage is equal to or smaller than a first threshold voltage at predetermined setting timing and executes the second control when the interelectrode voltage is larger than the first threshold voltage at the predetermined setting timing. A rate of the direct current in the second control is larger than a rate of the direct current in the first control.
