ABSTRACT:
Starting and operating circuit for gaseous discharge lamps having device for quickly restarting extinguished lamps while still hot includes means for reducing power supply voltage overshoot upon turn-on of the system. Circuit comprises a source of alternating current, an inductive regulator ballast having its input connected to the alternating current source, and a gaseous discharge lamp connected to the output of the ballast, a sine wave oscillator circuit having its input connected to the current supply and having its output connected to a transformer connected in series between the ballast and the lamp for stepping up and applying voltage to the lamp, a rectifier connected between the alternating current source and the oscillator circuit, the overshoot reducing means comprising a resistor connected between the rectifier and the oscillator circuit and a controlled switch for selectively connecting and disconnecting the resistor in the circuit.
