Gigabyte Technology has been granted a patent for a fan assembly that includes a base, a fan, a light-emitting unit, and a lighting effect component. The fan is rotatably disposed above the base and has multiple blades. The light-emitting unit is located between the base and the central part of the fan, while the lighting effect component surrounds the light-emitting unit. The lighting effect component has an inclined inner surface that reflects light emitted by the light-emitting unit away from the base.

A fan assembly with a larger light reflecting component
A recently granted patent (Publication Number: US11773860B2) describes a fan assembly with unique features. The fan assembly includes a base, a fan with blades, a light-emitting unit, and a light reflecting component. The fan is rotatably disposed above the base and has a central part with blades extending outwards. Each blade has a blade top surface away from the base. The light-emitting unit is located between the base and the central part of the fan, while the light reflecting component surrounds the light-emitting unit.
One notable aspect of the fan assembly is that the projection of the light reflecting component onto the base is greater than the projection of the fan onto the base. Additionally, the height of the light reflecting component protruding from the base is less than the distance between the blade top surface and the base. The light reflecting component has an inclined inner surface that faces the light-emitting unit in an inclined manner. This inclined inner surface allows the light emitted by the light-emitting unit to be reflected away from the base.
The patent also mentions other features of the fan assembly. It describes a fan guard that surrounds the fan and the light reflecting component, with a height greater than or equal to the distance between the blade top surface and the base. An arc reflector is also included, which is disposed on the central part bottom surface of the fan and rotates with the fan. The arc reflector has an opening through which a portion of the light emitted by the light-emitting unit can be reflected and incident on the inclined inner surface.
Furthermore, the fan assembly includes a light-collecting component that is disposed on the blade bottom surface of one of the blades. This light-collecting component extends towards the base and focuses a portion of the light emitted by the light-emitting unit on the inclined inner surface. The patent mentions that the light-collecting component can be a bar-shaped structure extending from one end of the blade bottom surface to the other end.
The inclination angle of the inclined inner surface is specified to be between 30 degrees and 60 degrees. The light-emitting unit comprises a red light-emitting diode, a green light-emitting diode, and a blue light-emitting diode. Lastly, the light reflecting component is in a closed annular shape.
Overall, this patented fan assembly incorporates various design elements to enhance the reflection and direction of light emitted by the light-emitting unit, resulting in an aesthetically pleasing and functional fan.
