  • Patent number: 6777878
    Abstract: 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.

  • Patent number: 6605899
    Abstract: The discharge tube (1) of a dielectric barrier discharge lamp is closed off in a gas-tight manner with the aid of a disk-like closure element (7) but without the use of joining elements. For this purpose, the discharge tube (1) has a constriction (10), which surrounds the edge of the disk-like closure element (7) in the form of a ring.
