Abstract: A control circuit for a discharge lamp, which can improve the lighting performance of the discharge lamp while realizing low power consumption, and a light source device are provided. The resistance value of the variable resistor (RC1, RC2) is not switched to the low resistance (R02) for steady discharge at the fourth time t4, but is switched to the low resistance (R02) at the fifth time t5, after lowering of power supply to the filament. With such control, a change in the lamp impedance is absorbed sufficiently by the variable resistor while power supply to the filament is being lowered and, therefore, destabilization of discharge is reduced and the lighting performance is improved.

Abstract: At an initial stage of a discharge start, a shield electrode is connected to a ground potential via a bidirectional voltage trigger switch. Thereafter, when an electrical charge within the shield electrode flows to the ground potential, by being triggered with this potential, both terminals of the bidirectional voltage trigger switch are disconnected therebetween. Thus, at an initial stage of discharge, charging of the shield electrode is suppressed to suppress a decline in discharge, and in a sustained discharge, destabilization due to an unwanted discharge from the shield electrode to the anode can be suppressed, and using such an electrode automatically allows improving the lighting performance of a discharge lamp.
