Abstract:
It is provided a dielectric barrier discharge lamp (10) for providing ultraviolet light, comprising an outer tube (12) filled with a discharge gas for providing ultraviolet light, an inner tube (14) arranged at least partially inside the outer tube (12), an outer electrode (16) electrically connected to the outer tube (12) and an inner electrode (18) electrically connected to the inner tube (14), wherein the inner electrode (18) comprises a conductor (20) and a plurality of an conductive granulated material (22) for providing an electrical contact between the conductor (20) and the inner tube (14). Due to the conductive granulated material (22) an electrical contact between the conductor (20) and the inner tube (14) is safeguarded and different thermal expansions of the inner electrode (18) and the inner tube (14) are compensated at the same time without applying mechanical stress to the inner tube (14). This leads to a dielectric barrier discharge lamp (10), which comprises an increased life time without the need for external cooling.
