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).
