Description

Luminous fan

This model relates to a fan, especially a luminous fan.

With the advancement of technology, the functions of computers and other 3C products are becoming more and more diversified, and the operating efficiency is getting higher and higher, so that the internal electronic components generate more heat, so most of the electronic components require heat dissipation devices. To dissipate heat, to prevent the high temperature of electronic components from affecting performance and stability during operation. Among them, a cooling fan is a common heat sink.

In recent years, the e-sports industry has been booming. Many computer accessories such as mice, keyboards or mainframes will be equipped with lighting to make the overall appearance more cool and colorful. However, the general cooling fan has a rotating structure, so it is more on the market. Few fans with luminous effect.

In view of this, the creators of the new type devote themselves to the above-mentioned shortcomings of the existing technology, especially concentrated research and the application of academic theory, try their best to solve the above problems, which becomes the goal of the new type of creators' improvement.

The main purpose of the present invention is to make the fan have a luminous effect when rotating.

In order to achieve the above-mentioned object, the present invention provides a light-emitting fan, which includes a bearing base, a fan wheel, a light guide element and a light-emitting unit. The bearing base includes a base plate and a pivot part connected to the base plate. The fan wheel is rotatably connected to the pivotal part. The fan wheel includes a hub, a hollow shaft connected to the hub, and a plurality of fan blades extending from the hub. The hub is provided with a light outlet, and the light guide element is arranged inside the hollow shaft. Extending to the light outlet, the light emitting unit is fixed on the base plate and projected on one end corresponding to the light guide element.

The new model also has the following effects: the light can be effectively emitted from the periphery of the wheel hub through the extension block corresponding to the light outlet. With the luminous body formed in the shaft hole, the light emitted by it can be transmitted to the light outlet through the light guide element in the hollow shaft and then emitted. Through the refraction structure on the light guide element, the light emitted by the luminous body can be refracted to the surroundings and then emitted from the light outlet.

Wherein, the bottom of the seat plate 11 is provided with a cavity 13, and the light-emitting unit 40 includes a circuit board 41 and a light-emitting body 42 provided on the circuit board 41. The light-emitting body 42 can be a light emitting diode (LED) or a light emitting diode (LED). The light bulb, the circuit board 41 is installed in the cavity 13 and the luminous body 42 is located in the shaft hole 121, so that the light emitted by the luminous body 42 can be conducted to the light outlet 211 through the light guide element 30 in the hollow shaft 22 After shooting.

In particular, the light guide element 30 is formed by injection molding of glass, quartz, polycarbonate (PC) or acrylic (PMMA), which is widely used in light source equipment, UV light boxes, LED light guides, projection light boxes and projection light Lenses, etc., the principle of the light guide element 30 is to guide light through countless internal reflections, and regardless of the spectral characteristics of the incident light source, it can make the originally uneven light uniform and guide the light to the needs Wherein, the light guide element 30 has a variety of shapes such as a cylinder, a cone, a 4-sided, a 6-sided, and an 8-sided, and the shape and thickness can be selected according to different needs.

To further illustrate, the light guide element 30 is provided with a refraction structure 34 at the center of the top end, through which the refraction structure 34 can effectively refract the light emitted by the luminous body 42 around and then exit the light exit 211.

Wherein, the supporting base 10 also extends with a plurality of supporting arms 14, and each supporting arm 14 is respectively provided with a fixing hole 141, and each fixing hole 141 is respectively used for a screw element to lock the supporting base 10.

Please refer to FIG. 5, which is the second embodiment of the present invention. The hub 21 is also provided with another light outlet 211, so that the two light outlets 211 are arranged oppositely, and the light guide element 30 is correspondingly protruding with another extension block 31. This can make the light when the fan rotates more uniform.

In summary, this new model has industrial applicability, novelty and advancement, and fully meets the requirements of a patent application. The application is filed in accordance with the Patent Law. Of course, the present invention can also have various other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can evolve various corresponding changes and modifications according to the present invention, but these corresponding changes Both the deformation and the deformation should belong to the protection scope of the patent applied for this model.
