2074265 9110751 PCTABS00006 A device for treating the surfaces of workpieces with light beams, comprising a reflector and an arc lamp, can treat large areas of workpieces. To this end, the reflector (1) has an elliptical cylindrical surface (11). A powerful long-arc lamp (2) is arranged at or near the focus of said surface nearer the reflector. The workpiece (3) to be treated is arranged on or near the line focus (4) remote from the reflector, on which the surface (11) focuses the light. The reflector can be tilted in several directions in relation to the surface of the workpiece so that the treatment track width can be adjusted and the heat in the radiation focus controlled. In addition, diaphragms and mirrors for reducing the irradiated surface are provided.
