1. An ultraviolet-C light radiation disinfection fixture comprising:
a tray, said tray including:
a base plate;
at least one side wall, said at least one side wall is positioned at a ten degree outward angle relative to a perpendicular vertical that extends upward from said base plate; and
at least one end plate;
a top plate;
at least one louver mount;
at least one ultraviolet-C light radiation source to disinfect and sterilize an air flow;
a sterilization field outside said ultraviolet-C light radiation disinfection fixture;
a sterilization chamber within said ultraviolet-C light radiation disinfection fixture;
a plurality of ultraviolet-C light radiation reflective louvers, said plurality of ultraviolet-C light radiation reflective louvers sized and positioned proximate one another, to direct ultraviolet-C light radiation from said ultraviolet-C light radiation source to the exterior of said ultraviolet-C light radiation disinfection fixture to create said sterilization field outside said ultraviolet-C light radiation disinfection fixture to eradicate bacterial, viral or pathogen particles from the air flow surrounding said ultraviolet-C light radiation disinfection fixture, said plurality of ultraviolet-C light radiation reflective louvers sized and positioned proximate one another to direct ultraviolet-C light radiation from said ultraviolet-C light radiation source in the interior of said ultraviolet-C light radiation disinfection fixture to create said sterilization chamber inside said ultraviolet-C light radiation disinfection fixture and said plurality of ultraviolet-C light radiation reflective louvers sized and positioned proximate one another to allow passage of the air flow containing a cloud of infectious bacterial, viral or pathogen particles to pass through said sterilization chamber within said ultraviolet-C light radiation disinfection fixture to eradicate bacterial, viral or pathogen particles from the air flow; and
wherein said plurality of ultraviolet-C light radiation reflective louvers are positioned to limit the scatter of ultraviolet-C light radiation outside said ultraviolet-C light radiation disinfection fixture to protect humans and animals present in an enclosure while said ultraviolet-C light radiation disinfection fixture is operational.
