The light is diffused and emitted through the light guiding diffusion ring, and the light guiding diffusion ring is assembled on the fan frame; the fan blade is embedded in the fan slot of the fan frame, and the middle seat of the fan blade is corresponding to the central axis assembly positioning inside the fan slot A second light source is assembled on the middle seat of the fan blade, whereby when the heat dissipation fan is in operation, the first light source and the second light source emit light to form a double aperture effect.

In the above solution, the fan slot of the fan frame is provided with a ring groove, and the first light source is positioned in the ring groove. The first light source is composed of a ring-shaped PCB board and a patch LED, and the patch LED is on the side of the ring PCB board. Uniform circumferential distribution; the light guiding diffusion ring is assembled along the inner wall of the fan slot to cover the first light source, and the light guiding diffusion ring surrounds the fan blade.

In the above solution, the outer circumference of the light guiding diffusion ring is provided with a buckle, and the buckle is inserted corresponding to the buckle groove designed on the fan frame, thereby achieving positioning and assembling of the light guiding diffusion ring on the fan frame.

In the above solution, the second light source comprises a PCB circular plate and an LED lamp assembled on the PCB circular plate, the second light source is disposed inside the middle seat of the fan blade, and a through hole is reserved on the PCB circular plate for the middle shaft to pass through; The leaves have light-diffusing properties.

In the fan slot of the fan frame, the first light source is assembled and the second light source is assembled on the middle seat of the fan blade. When the heat dissipation fan is in operation, the first light source and the second light source emit light to form a double aperture effect. The first light source and the second light source can be controlled by an external program to generate a variety of lamp colors and running light changes, which are not affected by the processed material, and can exhibit various lamp colors and mode changes, making the aperture fan more colorful and charming. .

Another advantage of the novel is that the structure is simple, easy to manufacture, structurally good, and easy to maintain.

Figure 1 is a schematic view showing the structure of a preferred embodiment of the present invention.

2 is a schematic exploded view of the embodiment of FIG. 1.

The concept, the specific structure and the technical effects produced by the present invention will be further described in conjunction with the accompanying drawings to fully understand the objects, features and effects of the present invention.

Please refer to FIG. 1 and FIG. 2 , which are schematic structural diagrams of a preferred embodiment of the present invention. The present invention relates to a light-emitting cooling fan, which has a fan frame 1 and a fan blade 2 . The fan frame 1 has an integrated structure. The fan frame 1 has a fan slot 11. The fan slot 11 is internally provided with a central shaft 12. The fan slot 11 of the fan frame is assembled with a first light source 3, and the light emitted by the first light source 3 passes through a light guiding diffusion ring. 4 diffused emission, the light guiding diffusing ring 4 is assembled on the fan frame 1, and the light emitted by the light source 3 of the first light source 3 is diffused and diffused through the light guiding diffusing ring 4 to form an entire light emitting ring. The fan blade 2 is embedded in the fan slot 11 of the fan frame. The middle seat 21 of the blade 2 is assembled and positioned corresponding to the central axis 12 inside the fan slot, and the second light source 5 is assembled on the middle seat 21 of the blade 2. Thereby, when the cooling fan is in operation, the first light source 3 and the second light source 5 emit light to form a double aperture effect; the first light source 3 and the second light source 5 can also generate various light color and running light changes through external program control. It is not affected by the processed materials, and can display a variety of lamp colors and patterns, making the aperture fan more colorful and charming.
