Abstract
The irradiation device for drying and/or curing paints, varnishes and similar coatings (13, 14) has at least one UV high-power radiator having a discharge space (3) filled with filling gas. The filling gas contained therein emits radiation under the effect of silent electrical discharges. The discharge space (3) is bounded by walls (1, 2), at least one wall consisting of dielectric material and being transmissive to the radiation generated in the discharge space (3). A pair of electrodes (4, 5), with an AC source (10) connected to the two electrodes, serves for feeding the discharge. The treatment space (6) is immediately adjacent to the dielectric (1, 2). The electrodes (4, 5) are positioned at a distance from the immediately neighboring dielectric. The coupling of the electrical energy from the electrodes into the discharge space takes place essentially capacitively. In this way, as well as the discharges in the actual discharge space (3), which are responsible for the generation of UV or VUV radiation, there also occur in the treatment spaces (6, 7) electrical discharges which, along with the radiation produced in the discharge space (3), additionally act catalytically on said c…
