Abstract
The invention relates to a radiation device that includes a housing, a light-emitting unit and a light-absorbing unit which is provided with an inlet opening and a reflector element. The reflector element extends across the entire distance between the light-emitting unit and the inlet opening of the light-absorbing unit.
Claims22
An irradiation appliance, having:
- a housing;
- a single light-emitting unit which is arranged in the housing;
- a light-receiving unit comprising an optical wave guide and having an inlet opening;
- and
- a reflector element having an inner surface in the shape of a truncated cone,
- wherein the reflector element extends over the entire distance between the light-emitting unit and the inlet opening of the light-receiving unit and has a smaller and a larger opening;
- and
- wherein the smaller opening faces the light-emitting unit, and the larger opening faces the light-receiving unit.
