1. A method for igniting and operating a dielectric barrier discharge lamp with elongated electrodes (A, K), comprising the steps of:
dividing at least one elongated electrode into two component electrodes (A, A′) by a gap (L),
in an ignition phase, applying an ignition voltage between the two component electrodes (A, A′) in such a way that an auxiliary discharge is ignited in a region of the gap (L) between the two component electrodes (A, A′), and
in normal operation, applying an operating voltage between the elongated electrodes (A, K) in such a way that a main discharge (E) burns between the electrodes (A, K).
