Abstract

A discharge lamp operating device includes an inverter (10b); ballast elements (C1 to C4); and discharge lamps (1a to 1d). The inverter (10b) inputs a DC voltage (Vin) and converts it into a first AC voltage (V2) having a ground as a reference potential and a second AC voltage (V3) having a ground as a reference potential, an inverse voltage phase with respect to the first AC voltage, and a small voltage value. The inverter (10b) outputs the first AC voltage from a first output terminal and the second AC voltage from the second output terminal. The ballast elements (C1 to C4) have one end connected to the first output terminal. The discharge lamps (1a to 1d) are connected between the other end of the ballast element and the second output terminal.
