ABSTRACT:
The high-power radiation source for visible light includes a discharge space (4) bounded by dielectrics (1, 10) and filled with a noble gas or gas mixture. Adjacent to the dielectrics (1,10) are luminescent coatings (5,11). Both the dielectric (1,10) and the electrode (6,12) situated on the surfaces of the dielectrics facing away from the discharge space (4) are transparent to the radiation generated by the dark electrical discharges. In this way, a large-area radiation source with high efficiency is provided which can be operated with high electrical power densities of up to 50 kW/m.sup.2 of active electrode surface.
