Abstract

The subject of the present invention is a dielectric barrier discharge (DBD-) lamp (1) for generating and emitting ultraviolet radiation comprising: —a housed discharge gap (3), whereby the housing has at least two walls, whereby at least one of the walls is a dielectric wall and at least one of the walls has an at least partly transparent part, a filling located inside the discharge gap (3), at least two electrical contacting means for electrical contacting associated with at least the two walls, respectively, whereby the discharge gap (3) is formed by at least two discharge sub-volumes (7) and/or discharge sub-areas (8) differing in at least one of their discharge parameters for realizing at least two dominant emission regimes and/or one emission regime with different radiant intensities and a method for producing said DBD-lamp (1).
