Ceiling fan with germicidal capabilities

Abstract

A fan for generating germicidal light is disclosed, which may be adapted to mount to a ceiling. The fan includes a hub connected to a plurality of fan blades. A motor is adapted to rotate the hub. A support is adapted to support the hub and motor from the ceiling. A lighting module may include a tray adapted to receive the support, the tray including one or more lights for providing ultraviolet germicidal light. The light may be provided by LEDs on a circuit board adapted for positioning around the support without dismounting the support from the ceiling, such as one comprised of wedge-shaped segments. The modular circuit board may form part of an uplight module supported by a housing for the motor.

1 . A fan adapted to be mounted to a ceiling, comprising:
 a hub connected to a plurality of fan blades;   a motor adapted to rotate the hub;   a fan motor controller;   one or more lights connected to the fan for providing ultraviolet germicidal light;   a remote control for providing a speed reference signal to the fan motor controller to indicate a desired fan speed; and   a light control board for monitoring the speed reference signal and controlling the one or more lights.   
     
     
         2 . The fan according to  claim 1 , wherein a time counting circuit in the light control board tracks the amount of time the one or more lights are turned on. 
     
     
         3 . The fan according to  claim 2 , wherein once an accumulated time reaches a defined threshold, the light control board is adapted to signal to a user that it is time to replace the one or more lights. 
     
     
         4 . The fan according to  claim 2 , wherein the light control board is adapted to turn the one or more lights on or off for a defined period of time to indicate to the user the need for service or replacement of the one or more lights. 
     
     
         5 . The fan according to  claim 1 , wherein the indication that the fan speed is above the pre-determined amount is provided by a light control board for monitoring a speed reference signal.
