Patent ID: 7858956

Claim:
An irradiation unit for UV irradiation of substrates, having a box-shaped housing, a rod-shaped UV lamp disposed therein, and a reflector arrangement that extends along the UV lamp, wherein the reflector arrangement has a support profile held in the housing and at least one reflector profile selected from a plurality of reflector profiles having along respective reflective surfaces at least one of different reflector geometries and different surface coatings, wherein the at least one reflector profile is connected with the support profile as a modular system, wherein each reflector profile of the plurality of reflector profiles is configured as a molded part having a stable shape, has an elongated body with a uniform cross-section over an entire length of the reflector profile, and can be releasably connected with the support profile by way of a first uniform connection surface on a backside of the reflector profile, the first uniform connection surface facing away from the reflector surface of the reflector profile and having a shape fit over a large area with a second uniform connection surface of the support profile, wherein a first shape of the first uniform connection surface is independent of the reflector geometry and is complementary to a second shape of the second uniform connection surface, and wherein the support profile is held in reciprocal surface contact with the respective reflector profile by way of connection means.
