Abstract
The invention relates to a housing for a detection unit for optically detecting smoke particles. The detection unit has a light source for emitting radiation to be scattered by smoke particles to be detected and a light detector for detecting the scattered radiation. The housinghas a cylindrical outer surfacehaving smoke openingsthrough which the smoke particles enter housing, and a radially symmetric light-guiding structurewith guide members. The guide members are so designed that adjacent guide members each form a guide channel through which the radiation emitted from the light source and not scattered by the smoke particles is guidable to the outside in the direction of the smoke openingsby multiple reflection. Higher detection sensitivity for optically detecting smoke particles can be achieved as a result.
