Light module for air treatment units
The present invention provides an air treatment unit including a module power socket; an air treatment duct having an interior defining an air path; and an ultraviolet light module that selectively engages the air treatment duct, the ultraviolet light module including a housing having a baffle; an integral ultraviolet light source and light source socket, the ultraviolet light source being fixed to and extending through the baffle; and a connector that selectively mates with the module power socket, the connector being in power transmissive communication with the light source socket, wherein, when the ultraviolet light module selectively engages the air treatment duct and the connector selectively mates with the module power socket, the ultraviolet light module cannot be fully removed from its engagement with the air treatment duct without disconnecting the power.
1. An air treatment unit comprising:
a module power socket;
an air treatment duct having an interior defining an air path between a top and bottom of said air treatment duct, said module power socket being located proximate said top; and
a light module comprising:
a housing having a baffle, a side wall and a lip, said lip selectively engaged with said top of said air treatment duct, with said sidewall extending downwardly from said lip so that said baffle extends across said air path;
an integral ultraviolet light source and light source socket, said ultraviolet light source being fixed to said light source socket, which is fixed to said baffle, said integral ultraviolet light source and light source socket extending through said baffle, such that said interior of said air treatment duct is exposed to ultraviolet light from said ultraviolet light source when said ultraviolet light source is powered; and
a connector located at said lip of said housing, said connector mating with said module power socket, said connector being in power transmissive communication with said light source socket such that said light module cannot be fully removed from its engagement with said air treatment duct without disconnecting the mating of said connector and said module power socket.
2. The air treatment unit of claim 1 , wherein said housing of said light module includes a connector flange having an aperture that aligns with said module power socket.
3. The air treatment unit of claim 1 , wherein said ultraviolet light source provides UV energy corresponding to a wavelength of from about 100 to about 280 nanometer.
