Abstract
A dielectric barrier discharge lamp having a cap (), an elongate discharge vessel () and strip-like outer electrodes () has a corresponding contact spring () for each outer electrode. These contact springs are arranged in the interior of the cap. The cap also includes a cap sleeve (), which surrounds one end of the discharge vessel () in such a manner that the or each strip-like outer electrode () is in electrically conductive contact with the or a corresponding contact spring (). 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.
