Abstract

A device for operating a gas discharge lamp is disclosed which includes a voltage transformer preferably an inverse transformer, to whose output a bridge circuit is connected, with the lamp being disposed in the diagonal of the bridge. A component disposed in the vicinity of lamp and able to carry an electrical potential is arranged in such a manner that an electrical field is able to develop between the lamp and the component. The component is connected with that terminal at the output of the voltage transformer at which the potential is positive relative to that at the other terminal.
