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.

Ceiling fan with germicidal capabilities

Lighting module for a fan

An apparatus includes a fan and a controller configured for controlling the fan to operate in a first mode limiting rotational speed of the fan within a first range of speeds between a first minimum speed and a first maximum speed. The controller is further configured to control the fan to operate in a second mode limiting rotational speed of the fan within a second range of speeds between a second minimum speed and a second maximum speed. The second range of speeds may be narrower than the first range of speeds. Related methods are also disclosed.

Fan with increased efficiency mode

A fan is for improving air quality, such as in an indoor environment. The fan includes a motor and a rotatable hub coupled to the motor. At least one fan blade includes a first end portion coupled to the rotatable hub and a second end portion radially distant from the rotatable hub. At least one ion generator is carried by the second end portion of the at least one fan blade, such as by a winglet associated therewith. A stationary tube passes through the rotatable hub including a conduit for transmitting power. A rotary coupling is also provided for transmitting power from the conduit to the at least one ion generator.
