Abstract:
A variable speed fan device includes a housing, a motor, a fan blade, a controller, and a first plurality of discrete light sources. The motor is maintained by the housing and the fan blade is connected to the motor. The controller is electronically coupled to the motor and manages an operational status of the variable speed fan device. The light sources are adapted to emit light from the display panel along a discontinuous perimeter at the exterior face. In an activated state, the light emitted by each light source is visually perceptible an exterior face of the display panel. The controller is programmed to individually activate and deactivate the light sources in a predetermined pattern creating a perception of movement of light about the discontinuous perimeter at the exterior face of the display panel corresponding with an operational status of the variable speed fan device.
