First Claim
Patent Images
1. A disinfection unit comprising:
- a housing comprising a blower or fan for blowing air;
a transparent tubular member for receiving air blown by said blower or fan and for directing it in a predetermined direction;
a plurality of ultraviolet light sources supported by said housing and arranged in a predetermined pattern around said transparent tubular member such that, when said plurality of ultraviolet light sources are energized, said plurality of ultraviolet light sources project ultraviolet radiation outward to facilitate sterilizing an environment outside said housing, said plurality of ultraviolet light sources also projecting ultraviolet radiation through said transparent tubular member to facilitate sterilizing air blown through said transparent tubular member; and
a controller coupled to said blower or fan and said plurality of ultraviolet light sources for controlling operation of the disinfection unit.

Abstract
A system, unit, device and method are shown for providing substantially simultaneous disinfection of bacteria or other pathogens in air passing through the system using C-band ultraviolet radiation from an ultraviolet light source and that is also capable of substantially simultaneous and efficient disinfecting air and surfaces outside the device using the same ultraviolet light source.

17. An air-surface disinfector comprising:
-
a transparent tubular member defining a passageway for receiving air and for directing said air in a predetermined direction; and a plurality of ultraviolet light sources arranged in a predetermined pattern such that, when said plurality of ultraviolet light sources are energized, ultraviolet radiation is projected inwardly through said transparent tubular member to facilitate sterilizing air passing through said transparent tubular member and outwardly to facilitate sterilizing an environment or area around said plurality of ultraviolet light sources. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method for disinfecting an area or environment, said method comprising the steps of:
-
arranging a plurality of ultraviolet light sources in a predetermined order such that they generally surround a predetermined interior disinfecting area; directing infected air through said predetermined interior disinfecting area; energizing said plurality of ultraviolet light sources so that they radiate said predetermined interior disinfecting area and disinfect said infected air that passes therethrough; said plurality of ultraviolet light sources generating ultraviolet light that radiates away from said predetermined interior disinfecting area to also disinfect air surrounding said plurality of ultraviolet light sources and at least one surface in said area or environment in which said plurality of ultraviolet light sources are energized. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40)
