ABSTRACT:
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 (14a,14b;15a,15b) by a gap in the longitudinal direction. This makes it possible, as intended, to operate one element (14a,15a) of the electrode elements separately from the other element (14b,15b) and, as a result, to cause either only one part of the lamp to illuminate or the entire lamp. For this purpose, one element (14a,15a) of the electrode elements is connected to a first operating device (22), and the other element (14b,15b) to a second operating device (21).
