Abstract

A light-emitting fan includes a fan frame, an impeller, a circuit board and a light-emitting component. The impeller includes a light guiding hub and a plurality of blades. The light guiding hub is disposed on the fan frame. The light guiding hub has an outer top surface, an outer annular surface, an inner annular surface, and a recess. The outer annular surface is connected to the outer top surface, the inner annular surface faces away from the outer annular surface. The blades are connected to the outer annular surface. The recess is located at the inner annular surface so as to form a light guiding protrusion of the light guiding hub. The circuit board is disposed on the fan frame. The light-emitting component is disposed on the circuit board. Light generated by the light-emitting component is emitted from the outer top surface through the light guiding protrusion.
