Abstract
A dielectric barrier discharge lamp has elongated electrodes ( ) that are arranged on the inside of the wall of the discharge vessel ( ) and are covered by a dielectric layer ( ). Arranged on the outside of the wall of the discharge vessel ( ) is an electrically conductive means ( ) 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.
