Dielectric barrier discharge lamp having an ignition means

摘要

A dielectric barrier discharge lamp has elongated electrodes (3) that are arranged on the inside of the wall of the discharge vessel (2) and are covered by a dielectric layer (4). Arranged on the outside of the wall of the discharge vessel (2) is an electrically conductive means (8) that is limited with reference to the longitudinal axis to a subregion (B) of the discharge vessel wall, for example a metal ring. The startability of the dielectric barrier discharge lamp when first being started or after long operational pauses is improved thereby.
