Patent attributes
A lamp appliance for emitting UVC light for disinfection is shown and described. The appliance includes timing controls settable by the user to control time of UVC emission and to provide a delay feature enabling a user to set the controls and exit a vicinity being treated by the lamp prior to UVC being emitted. Manual controls are redundant, including a first general power switch for bringing power to control electronics, and also a second switch initiating UVC emission. The appliance includes an illuminated display to annunciate time settings. The UVC element is pivotal on the chassis, to adjust direction of UVC emission. In one position, the UVC element is shielded to limit UVC emission to a limited size target. A remote controller is provided. The appliance is arranged with its length vertically oriented, to occupy minimal floor space.
