A dielectric barrier discharge lamp (1) with a discharge vessel, which has an outer tube (2), which surrounds a discharge space (4) filled with a discharge medium, an outer electrode (6), which is arranged on the outer side of the outer tube (2), an elongate inner electrode (7), which is arranged axially within the outer tube (2), at least one retaining disk (8) with an axial bore, through which the elongate inner electrode (7) runs, the retaining disk (8) extending substantially from the inner electrode (7) up to the inner side of the outer tube (2), as a result of which the inner electrode (7) is centered at least indirectly within the discharge vessel. The retaining disk (8) is supported on both sides loosely in the direction of the longitudinal axis by means of a supporting means (9a-9c) on the left-hand side and a supporting means (10a-10c) on the right-hand side. |
