Abstract
A dielectric barrier discharge lamp is disclosed, which has a discharge vessel enclosing with a wall a discharge volume filled with discharge gas. There is a phosphor layer within the discharge volume. The discharge lamp comprises first and second sets of interconnected electrodes, which are isolated from the discharge volume by at least one dielectric layer. At least one of the dielectric layers is the wall of the discharge vessel. Both the first and second sets of electrodes are located external to the discharge vessel. Advantageously, the discharge vessel comprises an outer tubular portion with an internal surface and an inner tubular portion with an outward surface. The outer tubular portion surrounds the inner tubular portion, and the discharge volume is enclosed between the internal surface of the outer tubular portion and the outward surface of the inner tubular portion.
