Abstract (en)
The radiator, which has dielectrically hindered discharge, has a flat in homogeneous electrode geometry (2a,2b,2c) for local modulation of the area light density. Electrodes (2) are divided into separately operable groups for independently switched operation An Independent claim is also included for an internal room light with a flat radiator
