In the dielectric barrier discharge lamps according to the invention, the elongate, for example strip-like or linear, electrodes are each separated into two electrode elements ( 14 a, 14 b; 15 a, 15 b) by a gap in the longitudinal direction. This makes it possible, as intended, to operate one element ( 14 a, 15 a) of the electrode elements separately from the other element ( 14 b, 15 b) and, as a result, to cause either only one part of the lamp to illuminate or the entire lamp. For this purpose, one element ( 14 a, 15 a) of the electrode elements is connected to a first operating device ( 22 ), and the other element ( 14 b, 15 b) to a second operating device ( 21 ).
