Patent ID: 8791441

Claim:
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.
