The invention relates to a method for operating a discharge lamp, which has at least one dielectrically impeded electrode (2, 3), on a flyback converter, which applies periodically recurring voltage pulses to the discharge lamp (La1). If the discharge lamp (La1) has a starting aid (10), the voltage amplitude (US) of the voltage pulses is successively raised until a dielectrically impeded discharge is formed in the discharge lamp, and until the voltage amplitude (US) has reached the nominal operating voltage. If the discharge lamp (La1) has no starting aid, a first discharge which causes a partial ionization of the discharge medium is firstly ignited in the discharge lamp (La1). Immediately after the first discharge has been brought back to extinction, a dielectrically impeded discharge is ignited anew, and the voltage amplitude (US) of the voltage pulses is increased until the nominal operating voltage of the discharge lamp (La1) is reached. |
