摘要: The present invention utilizes a system of primarily metallic pairs of mirrors, at 90° angles to each other and at 45° angles to the conduit axis, which cover only one inner wall of a fluid conduit in a parallel arrangement, while the other walls are simply mirrored. The useful radiation from e.g. UV light-emitting diodes comes through small breakthroughs in the valley bottom between two mirrors of a pair concentrated into the conduit. The double reflection in the pairs of mirrors sends the radiation back to where it came from in each section of the conduit—at least the axial component—while at the same time a lateral offset of the beams causes a chain reflection around the walls of the conduit, although this only in a defined area takes place, which has approximately the same extent as the beam cone of the light source on the opposite wall, which is also slightly concave in order to achieve better bundling of the rays. The radiation level in the delimited section intensifies even more chain reflections can take place.
This makes it possible to achieve considerably high irradiation values in the conduit even with a relatively weak UV light source and thus ensure very effective disinfection of the fluids contained therein.
