ABSTRACT:
To provide for reliable starting of lamps under cold or warm condition, by pulse superimposition circuitry, an auxiliary capacitor (11) and a serially connected damping resistor (12) are integrated in the starter or igniter circuit. The series circuit of the auxiliary capacitor (11) and the damping resistor (12) forms, together with a choke or ballast (2) a series oscillatory circuit which is directly connected to act on the primary (8) of the pulse transformer (4, 13) and increases the lamp supply voltage during ignition. A semiconductor switching element (9), such as a four-layer diode, disconnects the oscillatory circuit after ignition, also interrupting the supply for the series oscillatory circuit, so that the lamp, after ignition, will receive only normal network supply power.
