Abstract
An ignition circuit arrangement and method for a discharge lamp, with which there is associated a supply circuit for providing an ac supply voltage to the lamp, includes an ignition transformer which is connected to a trigger circuit on the primary side and to the lamp on the secondary side for transmitting an ignition pulse; an input energy source for the ignition trigger circuit; a first switch means in the trigger circuit and a control means which actuates the first switch means. To assist with the ignition process, an energy storage means controllable by the control means, in particular a voltage source controllable by the control means, is arranged in the supply circuit in series with the gas-discharge lamp. The controllable energy storage means serves to provide an additional energy supply during the ignition process beyond the actual ac supply for the lamp.
