ABSTRACT:
An irradiator with a cooling nozzle which projects through an opening in a mirror and has an inlet opening for cooling air positioned at a set distance from the lamp, cooling air being drawn in by the inlet opening of the cooling nozzle for enabling light with a high light intensity to be emitted from the lamp by cooling it. In this way, a lamp with a small tube diameter can be efficiently cooled without reducing the light gathering power of the mirror, and the workpiece can be irradiated with light with a high peak intensity. Furthermore, a cooling nozzle of appropriate length and internal diameter can be chosen according to the external diameter of the lamp due to the focussing mirror and the cooling nozzle being formed as separate individual parts in one embodiment. In this way, the same minor can be used with lamps of different external diameters.
