Abstract

An ultraviolet lamp fixture for purifying the air within a room by means of passing the air over a plurality of hot cathode or other commercially available ultraviolet ray tubes. The tubes are mounted vertically within a decoratively covered, easily movable, pole-mounted housing having a motorized fan which moves air through an opening in the lower portion of the housing over the tubes for purification. The purified air stream is exhausted through the top portion of the housing and returned to the room. The interior of the housing has deflector vanes which function to create a turbulent air flow in the area of the tubes to insure that all of the air passing through the lamp fixture is purified by contacting the lamps. The lamp fixture is provided with means for filtering the circulating air. In an alternate embodiment, the air passes through a dehumidifier prior to passing by the tubes.

Claims

1. An ultraviolet lamp fixture for purifying the air within a room, said fixture comprising:

a floor-to-ceiling tension supported pole;

a housing having a plurality of upright side walls;

means fastening a first of said housing walls to said tension supported pole such that said housing is supported in an upright position when said tension supported pole is positioned between a floor and a ceiling;

the lower portion and the upper portion of said housing being opened and respectively defining an air brake and an air outlet with the interior of said housing defining an air passageway between said air inlet and said air outlet;

a motorized fan releasably supported at said housing outlet for drawing air through said air intake into the interior of said housing and exhausting said air through said air outlet defined at the top of said housing;

means releasably securing said motorized fan between a pair of opposing side walls defining said housing;

a plurality of ultraviolet ray tubes mounted in said housing in said air passageway between said air inlet and said air outlet;

bracket means attached to adjacent side walls of said housing for supporting said tubes in an upright fashion in said air passageway;

a portion of a second of said side walls of said housing being pivotally attached to said housing to define an access door of a length at least equal to the length of said tubes to permit access to the interior of said housing to permit the dusting of the outer surfaces of said ultraviolet ray tubes without removing said tubes from said housing;

a circular decorative covering opened at opposite ends and encircling said housing and concealing the same, said cover being slidably movable with respect to said housing to permit removal of said covering from said housing to gain access to said door;

the space between said first-mentioned side wall of said housing and the opposing inner surface of said decorative cover being of a sufficient distance to permit the passage of said tension supported pole;

said decorative cover being releasably secured to said tension pole at spaced locations opposite said first-mentioned side wall.

2. The ultraviolet lamp fixture defined in claim 1 further comprising filter means removably attached to said housing at said air intake end of said housing to facilitate the replacement of said filter means, said filter means trapping pollen and dust and the like to remove the same from the airstream passing into the interior of said housing through said air intake.

3. The ultraviolet lamp fixture defined in claim 1 further comprising means disposed in said air passageway for deflecting said air flow and generating a turbulent air flow by said ultraviolet ray tubes.

4. The ultraviolet lamp fixture defined in claim 3 wherein said last-mentioned means comprises a plurality of punched-out portions of said side walls forming vanes disposed in the path of said airstream.

5. The ultraviolet lamp fixture defined in claim 1 further comprising means for dehumidifying the air prior to the passage of said air by said ultraviolet ray tubes.
