Abstract
A shielding arrangement for a rod shaped UV radiator, particularly for use in making the air in a room germ free which comprises a rod shaped UV radiator and a number of shielding plates which are held parallel to each other at a predetermined spacing. The shielding plates are aperture disks which are disposed horizontally in the room, each having a hole with dimensions such as to at least admit the UV radiator vertically in the direction of its rod axis. The holes of the individual aperture disks are axially lined up with each other. The shielding arrangement is dimensioned such that the UV light can emerge essentially only between respective adjacent aperture disks.
Claims45
In a shielding arrangement for a rod shaped UV radiator, comprising a plurality of shielding plates which are held parallel to each other at a predetermined spacing by a holding device, the improvement comprising:
- a. the shielding plates being aperture disks each of which has a hole of a size at least large enough for leading the UV radiator through it in the direction of its rod axis;
- b. the holes of all the individual aperture disks aligned axially with respect to each other;
- and
- c. the aperture disks matched to each other with respect to their hole dimension (2r), their outside dimension (2R), their thickness (d) and their mutual spacing (a) in such a manner that UV light which emanates from a section of the UV radiator located between two adjacent aperture disks when the UV radiator is placed axially through the aligned holes issues with a small aperture angle (.alpha.) essentially only between these two adjacent aperture disks but not between other aperture disks.
