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.
Claims10
A device for operating a gas discharge lamp comprising:
- a voltage transformer for transforming a direct voltage of an energy source into a predetermined direct output voltage, the voltage transformer having a first output terminal and a second output terminal, with the first output terminal having a potential which is positive with respect to a potential of the second output terminal;
- a bridge circuit having inputs connected to the first and second output terminals of the transformer and a diagonal connected to the lamp for providing an AC potential to the lamp;
- and
- at least one component capable of carrying an electric potential disposed in the vicinity of the lamp such that an electrical field develops between the lamp and the component, with the component being connected to the first terminal of the voltage transformer.
