Abstract:
Radiator module for insertion into a lamp housing with at least one discharge lamp as radiation source situated in the interior of the module which puts out an ultraviolet radiation produced by means of plasma in the interior of a discharge chamber, the plasma being formed by coupling an electromagnetic field into the discharge chamber and the radiation produced by the plasma issues along a given optical axis through at least a first body transparent to ultraviolet radiation as a window, at least one diaphragm with a through-bore is provided along the axis in the range of the plasma, and radiation produced along this axis by an additional radiation source penetrates through a second transparent body as an entry window into the discharge chamber, and exits along the axis through the first transparent body together with the ultraviolet radiation produced by the plasma, characterized in that the additional radiation source is fixedly disposed in a given position within the module along the optical axis the module being insertable into a mounting of the lamp housing with a coupling lens and locked and held in a given position with respect to the coupling lens by the mating fit of the module.
