Abstract

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.

Claims

1. A air treatment unit comprising:

a module power socket;

an air treatment duct having an interior defining an air path; and

a light module that selectively engages said air treatment duct, said light module comprising;

a housing having a baffle, said baffle extending across said air path when said light module engages said air treatment duct;

an integral ultraviolet light source and light source socket, said ultraviolet light source being fixed to and 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 light module engages said air treatment duct and said ultraviolet light source is powered; and

a connector that selectively mates with said module power socket, said connector being in power transmissive communication with said light source socket, wherein, when said light module selectively engages said air treatment duct and said connector selectively mates with said module power socket, said light module cannot be fully removed from its engagement with said air treatment duct.

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 when said light module engages said air treatment duct.

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 nanometers.
