Abstract
The invention relates to a method for operating a discharge lamp, which has at least one dielectrically impeded electrode ( ), on a flyback converter, which applies periodically recurring voltage pulses to the discharge lamp (La ). If the discharge lamp (La ) has a starting aid ( ), the voltage amplitude (U ) of the voltage pulses is successively raised until a dielectrically impeded discharge is formed in the discharge lamp, and until the voltage amplitude (U ) has reached the nominal operating voltage. If the discharge lamp (La ) has no starting aid, a first discharge which causes a partial ionization of the discharge medium is firstly ignited in the discharge lamp (La ). Immediately after the first discharge has been brought back to extinction, a dielectrically impeded discharge is ignited anew, and the voltage amplitude (U ) of the voltage pulses is increased until the nominal operating voltage of the discharge lamp (La ) is reached.
