<p>A dielectric barrier discharge lamp (1) comprises a discharge vessel (2) has a principal axis (6), the discharge vessel encloses a discharge volume filled with a discharge gas. The discharge vessel (2) further comprises end portions intersected by the principal axis (6). There are at least one electrode (3) of a first type and at least one electrode (4) of a second type in the lamp. The electrodes of one type are energized to act as a cathode and the electrodes of other type of are energized to act as an anode. The electrodes are substantially straight, elongated and have a longitudinal axis substantially parallel to the principal axis (6) of the discharge vessel (2). The electrodes (3, 4) are positioned within the discharge volume. The electrodes of at least one type are isolated from the discharge volume by a dielectric layer (5). A dielectric barrier discharge lamp is also disclosed, in which the electrodes (3, 4) are arranged within the discharge volume in groups, and each of the groups comprises one electrode (3) of the first type and at least one electrode (4) of the second type.</p> |
