A dielectric barrier discharge lamp ( 1 ) having a tubular discharge vessel ( 2 ) and a luminescent material layer on at least a part of the inner wall of the discharge vessel ( 2 ) and having elongate electrodes ( 3 ) is provided with a coating ( 10 ) on a partial region of the inner wall at least at one end of the tubular discharge vessel ( 2 ), which coating additionally covers an end of at least one elongate electrode ( 3 ) . The material of the coating ( 10 ) has a high secondary electron emission coefficient. As a result, the ignition behavior of the lamp is improved, in particular during ignition in darkness. |
