Abstract
A high-power radiator, especially for ultraviolet light, wherein in order to increase the efficiency in the case of UV high-power cylindrical radiators, the inner dielectrics (3) are very small in comparison with the outer dielectric tube. A privileged direction of radiation is achieved by eccentric arrangement of the dielectrics and outer electrodes (2) only on the surface adjacent to the inner dielectric (3), and simultaneous construction of the outer electrode (7) as a reflector.
Claims16
A high-power radiator, especially for ultraviolet light, comprising a discharge space (5), which is filled with a fill-gas that emits radiation under discharge conditions, and of which the walls are formed by a first tubular dielectric (1) and a second dielectric (3) that is provided on its surfaces averted from the discharge space (5) with first (2, 7) and second electrodes (4), and comprising an alternating current source (6) connected to the first and second electrodes for feeding the discharge, wherein inside the first tubular dielectric (1) a rod (3) of dielectric material is arranged in the interior of which an electrical conductor (4) that forms the second electrode is inserted or embedded.
