UV and IR radiator reflector - is spiral shaped reflector reproducing logarithmic or other geometric spiral

摘要

The reflector is for radiation generators, esp. for ultraviolet and infrared radiators having light sources with a slot shaped radiation outlet surface. The reflector is spiral shaped when viewed from the side and the radiation source is located inside the track of the centre of curvature of the reflector. The longitudinal extension of the reflector is made to correspond to that of the radiation source. The spiral shape of the reflector is a reproduction of a logarithmic spiral or alternatively of an amhimedic, hyperbolic or parabolic spiral.
