Abstract

An outwardly projecting air purifier including a support, a generally cylindrical array of UV lamp assemblies mounted to the support, wherein each UV lamp assembly includes a reflector having a generally parabolic inner surface and a UV lamp so mounted to the reflector that the inner surface of the reflector reflects a portion of the ultraviolet radiation emitted by the lamp in an outward, radial, direction is described herein. The air purifier also includes a convex shaped deflector element so mounted to the support that the airflow is deflected by the deflector element and brought near the lamps.

Claims

1. An outwardly projecting air purifier to be used in an air duct supporting a longitudinal airflow and comprising:

a support to be positioned within the air duct;

a plurality of UV lamp assemblies longitudinally mounted to said support;

each of said UV lamp assemblies including a reflector having a generally parabolic inner surface and a UV lamp so mounted to said reflector that said generally parabolic inner surface reflects UV radiation emitted by said UV lamp in a radial direction; and

a convex deflector element so mounted to said support that the airflow is deflected over said UV lamp assemblies.

2. An outwardly projecting air purifier as defined in claim 1, wherein said UV lamp assemblies are mounted to said support via first and second mounting plates.

3. An outwardly projecting air purifier as defined in claim 2, wherein said deflector is secured to said first mounting plate.

4. An outwardly projecting air purifier as defined in claim 3, wherein said deflector is so shaped as to cover said first mounting plate.

5. An outwardly projecting air purifier as defined in claim 1, wherein said UV lamp is secured to said reflector using clamps secured to said inner surface of said reflector.

6. An outwardly projecting air purifier as defined in claim 5, wherein said UV lamp is removably secured to said clamps.

7. An outwardly projecting air purifier as defined in claim 1 wherein said UV lamp is a germicidal lamp.

8. An outwardly projecting air purifier as defined in claim 1 wherein said UV lamp is an oxydizing and germicidal lamp.

9. An outwardly projecting air purifier as defined in claim 1, wherein said plurality of UV lamp assemblies are so positioned as to form a cylindrical array.

10. An outwardly projecting air purifier as defined in claim 1, wherein said reflector comprises aluminum.

11. An outwardly projecting air purifier as defined in claim 10, wherein said reflector comprises extruded aluminum.

12. An outwardly projecting air purifier as defined in claim 10, wherein said generally parabolic inner surface comprises aluminum.

13. An outwardly projecting air purifier as defined in claim 1, wherein said support comprises a threaded rod.

14. An outwardly projecting air purifier as defined in claim 1, wherein said plurality of UV lamp assemblies consists of five UV lamp assemblies.

15. An outwardly projecting air purifier as defined in claim 1, further comprising a plurality of filler pieces so mounted between adjacent reflectors as to prevent air from entering a free space present between adjacent reflectors.

16. An outwardly projecting air purifier to be positioned longitudinally within an air duct supporting an airflow comprising:

a support;

a convex shaped deflector element so mounted to said support as to be located upstream with respect to the airflow;

at least two reflectors having a generally parabolic inner surface mounted to said support; and

at least two UV lamps each being so mounted to a corresponding reflector that UV radiation emitted by said lamps is reflected in a radial direction;

wherein each of said at least two reflectors is so mounted to said support that airflow is deflected by said convex shaped deflector element over said UV lamps.

17. An outwardly projecting air purifier as defined in claim 16, wherein said reflectors are mounted to said support via first and second mounting plates.

18. An outwardly projecting air purifier as defined in claim 17, wherein said deflector is secured to said first mounting plate.

19. An outwardly projecting air purifier as defined in claim 18, wherein said deflector is so shaped as to cover said first mounting plate.

20. An outwardly projecting air purifier as defined in claim 16, wherein said UV lamps are secured to said reflectors using clamps secured to said inner surface of said reflectors.

21. An outwardly projecting air purifier as defined in claim 20, wherein said UV lamps are removably secured to said clamps.

22. An outwardly projecting air purifier as defined in claim 16, wherein said UV lamps are germicidal.

23. An outwardly projecting air purifier as defined in claim 16, wherein said UV lamps are oxydizing and germicidal.

24. An outwardly projecting air purifier as defined in claim 16, wherein said at least two reflectors includes at least three reflectors that are so positioned as to form a cylindrical array.

25. An outwardly projecting air purifier as defined in claim 16, wherein said reflector comprises aluminum.

26. An outwardly projecting air purifier as defined in claim 25, wherein said reflector comprises extruded aluminum.

27. An outwardly projecting air purifier as defined in claim 25, wherein said generally parabolic inner surface comprises aluminum.

28. An outwardly projecting air purifier as defined in claim 16, wherein said support comprises a threaded rod.

29. An outwardly projecting air purifier as defined in claim 16, further comprising a plurality of filler pieces so mounted between adjacent reflectors as to prevent air from entering a free space present between adjacent reflectors.

30. An outwardly projecting air purifier to be used in an air duct supporting a longitudinal airflow and comprising:

a plurality of adjacently interconnected UV lamp assemblies each including;

a reflector having a generally parabolic inner surface and an outer surface so configured as to be interconnectable with the outer surface of a reflector of an adjacent UV lamp assembly; and

a UV lamp so mounted to said reflector that said generally parabolic inner surface reflects UV radiation emitted by said UV lamp in a radial direction;

a convex deflector element so mounted to said reflectors that the airflow is deflected over said UV lamp assemblies.
