Ultraviolet radiation system
First Claim
1. An ultraviolet radiation system comprising;
- a plurality of UVC lamps providing UVC radiation;
a housing having multiple side walls, each side wall being adjacent to at least one of the plurality of lamps, the housing having an air chamber therein and each side wall having air vent openings in a pattern which confront substantially the entire length of the at least one adjacent lamps;
the plurality of UVC lamps and the air chamber arranged in a vertical orientation;
the at least one lamp adjacent each of the side walls being positioned adjacent the pattern of air vent openings in that side wall;
a fan in fluid coupling relationship with the housing to cause air to flow from the surrounding atmosphere into the housing and out through the pattern of vent openings in each side wall and across substantially the entire length of the at least one of the plurality of lamps adjacent each side wall into the surrounding atmosphere outside of the housing;
the UVC radiation being effective to simultaneously kill pathogens in the air of the surrounding atmosphere outside of the housing and on radiated surfaces in the surrounding atmosphere outside of the housing directly and by reflected radiation;
the flowing air being effective to cool the plurality of lamps to an optimum operating temperature to maximize the UVC radiation output from the plurality of lamps; and
a power source for energizing the one or more lamps and fan.

Abstract
The present invention provides an ultraviolet radiation system which generates UVC radiation with maximal radiation output and little or no degradation in radiation output during operation of the lamps. The system provides UVC radiation at a wavelength of 253.7 nm, which is effective to kill or deactivate pathogens on surfaces irradiated by the emitted UVC radiation and is simultaneously effective to decontaminate air which passes uniformly over the entire length of the UVC lamps. Uniformly flowing air cools the lamps to maximize the conversion efficiency of power input to the lamps to UVC radiation from the lamps, and at the same time decontaminates the flowing air such that air in the room is also decontaminated.

29. An ultraviolet radiation system comprising:
-
an elongated housing having a plurality of side walls, an upper portion open to the surrounding atmosphere, and a lower portion closed to the surrounding atmosphere; at least one tubular UVC lamp for providing UVC radiation, mounted adjacent to each respective side wall and having an electrical terminal at one or both ends; an upper and a lower connector associated with each side wall of the housing for mechanically and electrically connecting the respective electrical terminals of the at least one UVC lamp mounted adjacent the respective side walls of the housing; each side wall having an array of vent openings therethrough in a pattern substantially coextensive with the full length of the at least one UVC lamp; a fan disposed in the upper portion of the housing and operative to cause air to flow from the surrounding atmosphere downward in the housing and out through the array of vent openings on each side wall and across substantially the full length of each adjacent at least one UVC lamp into the surrounding atmosphere outside of the elongated housing; the UVC radiation being effective to simultaneously kill pathogens in the air of the surrounding atmosphere outside of the elongated housing and on radiated surfaces in the surrounding atmosphere outside of the elongated housing; the flowing air being effective to cool the one or more lamps to an optimum operating temperature to maximize the UVC radiation output from the one or more lamps; and a power source coupled to the connectors for energizing the UVC lamps and fan.
