ABSTRACT:
A dielectric barrier discharge lamp having a cap (2), an elongate discharge vessel (1) and strip-like outer electrodes (5a-5f) has a corresponding contact spring (7a-7f) for each outer electrode. These contact springs are arranged in the interior of the cap. The cap also includes a cap sleeve (6), which surrounds one end of the discharge vessel (1) in such a manner that the or each strip-like outer electrode (5a-5f) is in electrically conductive contact with the or a corresponding contact spring (7a-7f). Preferably, the transverse extent of the individual contact springs, at least in the region of the contact, is less than or equal to the width of the corresponding strip-like outer electrode. This design combines ease of installation of the cap with a reliable contact and a high lamp efficiency.
