Abstract

In a UV high-power radiator, the electrodes (6', 6") consist of wires embedded in a glass dielectric (3). The dielectric is arranged spaced between two UV-transparent sheets (1, 2). The discharge spaces (8, 9) are filled with a filler gas emitting radiation under discharge conditions. The surface discharges (10) form on the dielectric surface in each case between two adjacent electrode wires (6', 6"). A high-power radiator constructed in this manner is characterized by simple and economical construction and high UV yield.
