1. 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.
