UVC sterilization and lighting device
Lighting device that provides, in addition to effective LED illumination, controlled UVC treatment of an airflow that provides sterilization of the air without endangering those using the illumination or damaging the environment being illuminated. Some embodiments include variable light and sterilization control, with variables being timing, intensity and light color, for example.
1 . A combination LED light unit and a UVC sterilization device comprising:
a light emitting assembly;
a fan box connected to said light emitting assembly;
a fan located in said fan box;
a front cover, a back cover, and side baffles that form an air duct in operative connection with said fan;
an air inlet disposed on one side of said light emitting assembly for drawing contaminated air into said UVC sterilization device from a space;
an air outlet disposed on a side of said light emitting assembly different from the disposition of said air inlet; and
a germicidal and disinfecting air purifier apparatus for eliminating pathogens from said air and disinfecting said air from said light emitting assembly,
wherein said air outlet directs air treated with said germicidal and disinfecting air purifier apparatus back into the space.
2 . A combination LED light unit and a UVC sterilization device according to claim 1 wherein said UVC sterilization device comprises a UVC 2×2 direct/indirect troffer.
3 . A combination LED light unit and a UVC sterilization device according to claim 1 wherein said LED light unit comprises a color temperature control switch that selectively controls color temperature of the light emitted by the light emitting assembly.
4 . A combination LED light unit and a UVC sterilization device according to claim 1 wherein said UVC sterilization device comprises a UVC sterilization lamp that is within a cavity, and wherein the UVC sterilization lamp comprises a UVC-LED, and one or more walls of the cavity comprise a substrate for sterilizing air flowing through said cavity with an output from the UVC sterilization lamp.
5 . A combination LED light unit and a UVC sterilization device according to claim 1 and further including a night light.
6 . A combination LED light unit and a UVC sterilization device according to claim 1 and further comprising a control assembly for instituting and completing one or more the following functions:
air sterilization combined with LED lighting;
separate LED lighting;
night lighting; and
ventilation in combination with at least one of air sterilization, air sterilization with LED lighting, LED lighting, and night lighting;
wherein the control assembly comprises one or more of a wall switch, remote control switch, automatic temperature control switch, motion switch, humidity switch, and time switch.
7 . A combination LED light unit and a UVC sterilization device according to claim 1 , wherein the air inlet draws contaminated air into said UVC sterilization device from the space through the front cover; and
said air outlet directs air treated with said germicidal and disinfecting air purifier apparatus back into the space through the front cover.
8 . A combination LED light unit and a UVC sterilization device according to claim 1 , wherein the inlet is defined at one end of the air duct, the air outlet is defined at another end of the air duct, and the air outlet is disposed on a side of the front cover different from the disposition of the air inlet.
9 . A combination LED light unit and a UVC sterilization device according to claim 1 , further comprising a separator forming the air duct, wherein the side baffles and the separator form the air duct in a serpentine manner around the separator.
10 . A combination LED light unit and a UVC sterilization device according to claim 9 , wherein the germicidal and disinfecting air purifier apparatus includes a UV lamp fastened in the air duct, between the separator and one of the side baffles.
11 . A combination LED light unit and a UVC sterilization device according to claim 9 , wherein the germicidal and disinfecting air purifier apparatus includes UV lamps fastened to the back cover, at opposite sides of the separator.
