The control unit controls the discharge lamp driving unit so that an AC period alternately including a first AC period and a second AC period is provided. First AC current is supplied to the discharge lamp during the first AC period. Second AC current having a lower frequency than a frequency of the first AC current is supplied to the discharge lamp during the second AC period. When the inter-electrode voltage is not less than a first voltage, the control unit sets a ratio of the second AC period in the AC period to a first ratio. When the inter-electrode voltage is smaller than the first voltage and not less than a second voltage smaller than the first voltage, the control unit makes the ratio of the second AC period greater than the first ratio. When the inter-electrode voltage is smaller than the second voltage, the control unit makes the ratio of the second AC period smaller than the first ratio.SELECTED DRAWING: Figure 8
