Abstract

Lighting apparatus includes a dielectric barrier discharge lamp having a discharge vessel enclosing a discharge space having a filling, first and second main electrodes, a dielectric sheet between the first main electrode and the discharge space, and a first circuit part for generating an operating voltage between the main electrodes. A plurality of electrode bodies mounted in or on the dielectric sheet form an auxiliary electrode, and a second circuit part generates auxiliary voltages between the electrode bodies for generating an auxiliary discharge in the discharge space.
