Abstract: An air sterilization apparatus for sterilizing air that can include a fan assembly, which may be mounted in an upper-part of a room, and a UVC lamp to emit a UVGI field. The air sterilization apparatus may direct air across the UVGI field to sterilize the air. A baffle may also be provided to shield the eyes of occupants of the room from UVC energy contained in the UVGI field. The air sterilization apparatus may also include an illuminator lamp to provide illumination to a room.

Abstract: Accessories and methods for ceiling paddle fan fixtures for enhancing room air quality and killing common air borne viruses by air sterilization immediately within the room where the germs originate in a relatively large and diffuse sterilization zone at a relatively low UV radiation level through which a relatively high volume of air is circulated by a paddle fan.

Abstract: An UV-C air sterilizer with an optional visible light provides effective air sterilization through the use of a relatively low intensity UV-C radiation field external of the fixture and the continuous circulation of a mixture of treated and untreated air. Methods are also disclosed.

Abstract: A ceiling paddle fan fixture for improving the quality of the air in the room and various methods of enhancing room air quality, with particular application in public spaces such as hospitals, health care institutions, dormitories, schools and offices. A UV-C source and an air mover are combined in a single fixture which uses a low intensity UV-C source and a paddle ceiling fan to significantly increase the mixing of the treated with the untreated room air. Sterilization of room air is achieved by the passage of a high volume of air at a relatively slow speed through a relatively low intensity UV-C field.

Abstract: Methods and apparatus for the sanitation and surface disinfection of edible produce such as lettuce, spinach and other leafy vegetables and fruits and vegetables such as apples, plums, pears, tomatoes having a protective skin. A centrifuge for receiving washed produce may be selectively spun to remove excess washing fluid, irradiated with UV-C energy and/or exposed to an ozone field while within the centrifuge. Air may be used for evaporative drying of the washed produce.

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.

Abstract: In general, the present invention provides a personal air sterilization unit including an intake port; an exhaust port; a sterilization duct communicating in between the intake port and the exhaust port; an ultraviolet light source emitting ultraviolet light and retained within the sterilization duct to expose the interior of the sterilization duct to ultraviolet light; and means for drawing air into the intake port, forcing it through the sterilization duct, where it is treated by ultraviolet light, and thereafter forcing it out through the exhaust port to create a circulating air current encompassing a personal air space.

Abstract: A shade holder is provided for use with table and floor lamps having separately ballasted non-incandescent lamps. The shade holder includes the combination of a saddle and harp, the saddle having a central base element with spacer members extending angularly from opposite ends thereof. The harp is generally elliptical or oval in shape and is received by the saddle at ends of the angularly extending spacer members. The resultant shade holder provides for receipt of a disk-like or cylindrical ballast adjacent the saddle, with the ballast receiving an appropriate non-incandescent lamp, such as a high intensity discharge, inductive or compact fluorescent lamp. The saddle and harp are configured with appropriate angles and bends to accomodate both the ballast and the lamps while providing an aesthetically pleasing appearance.

Abstract: The present invention is a combination metal halide and auxiliary light bulb floor or table lamp which is suitable for home or office illumination. The lamp includes a lampholder module which provides a unitary housing for the bulb sockets and the electrical components required to operate the bulbs. The module also positions each bulb relative to the others to minimize shadowing which results when a bulb casts a shadow due to the light emanating from another bulb.
