Radiation source for emitting radiation in pulses with a duration and at intervals within chosen ranges, comprising at least one plate-shaped radiant element (1), and at least two electrical conductors coupled to the element(s). The source also includes at least one plate-shaped surrounding, thermally conductive element (2) being thermally coupled to a radiation element at its inner edge, and being thermally coupled to a cooling device (3) at its outer surface.
