Abstract: A cooling fan having a light-emitting effect comprises a frame body, a light-emitting assembly and a fan blade assembly, wherein the frame body has a base and an upper cover. The light-emitting assembly is mounted on the frame body and includes a circuit board, a plurality of light-emitting elements capable of emitting a light respectively and a light guide plate. The light guide plate includes a plurality of light guide strips which correspond to each of the plurality of light-emitting elements respectively to guide the light, and a light diffusion portion which is connected with the plurality of light guide strips. The light diffusion portion includes a first diffusion portion in a position corresponding to each of the plurality of light guide strips. The fan blade assembly is mounted in the frame body, such that the light passes through the first diffusion portions and then forms a diffused light.

Abstract: A fan frame, which embodies a blade assembly and a motor therein, has at least one LED socket mounted on a side thereof and having a hole and at least one set of snapping retention extended from both sides of the hole, and at least one light emitting diode mounted in its corresponding LED socket, wherein at least one set of snapping retention clips the rear portion of the light emitting diode after it is inserted into the hole.
