Abstract
A discharge lamp for dielectrically impeded discharge has a discharge vessel substantially in the form of a hollow cylinder whose discharge chamber is separated from at least one electrode by a dielectric; on the outer surface of the discharge chamber a spiral-shaped electrode in the form of a ribbon is disposed, which permits rays to pass through it, while on the outer surface of the discharge vessel facing inward toward the cylinder axis a second electrode is provided which is at least partially surrounded by the hollow-cylindrical surface. The surface covered by the first electrode corresponds to no more than 10% of the external surface of the discharge chamber. The discharge chamber comprises on its inner side a hollow space configured as a flow passage which is surrounded by the second electrode. The flow passage is provided in order to carry a liquid coolant--preferably deionized water.
