Description

Technical Field

[0001] This invention relates to a fan, and more particularly to a luminous fan. Background Technology

[0002] With the widespread adoption of personal computers and advancements in information technology, the functions and roles of personal computers have expanded beyond simply being transactional machines. Coupled with a wealth of peripherals and high-definition audio-visual output devices, personal computers are now commonly used as multimedia playback devices and important entertainment equipment.

[0003] Currently, many personal computers use transparent materials (such as acrylic) for their casings or cases, or employ a hollowed-out structure, combined with multi-color light-emitting diode (LED) light strips or full-color LED beads, giving personal computers a rich and colorful appearance.

[0004] To produce dynamic and colorful lighting effects, one known method for personal computers is to install multi-colored light-emitting diodes, light strips, or full-color LED beads in the computer fan. However, the design of current illuminated fans still faces bottlenecks in terms of light quality. Therefore, how to further improve the light quality of illuminated fans is one of the problems that researchers should solve. Summary of the Invention

[0005] The present invention provides a light-emitting fan, thereby further improving the light emission quality of the light-emitting fan.

[0006] An embodiment of the present invention discloses a light-emitting fan comprising a fan frame, a light-transmitting fan blade, a first light source module, and a second light source module. The light-transmitting fan blade is rotatably mounted on the fan frame. The light-transmitting fan blade includes a hub and a plurality of blades. The hub includes a cover plate and an annular side plate. The annular side plate is connected around the cover plate so that the cover plate and the annular side plate together surround an accommodating space. The annular side plate has an annular side surface and a light-incident inclined surface. The annular side surface faces away from the accommodating space. The light-incident inclined surface faces away from and is not parallel to the annular side surface. The blades are connected to the annular side surface of the hub. The first light source module is located in the accommodating space and is used to generate light to the cover plate. The second light source module is located in the accommodating space and is used to generate light to the light-incident inclined surface.

[0007] According to the above embodiment of the light-emitting fan, since the light-emitting fan is equipped with a first light source module and a second light source module, the hub of the light-transmitting fan blades can be evenly illuminated by the first light source module, and the blades of the light-transmitting fan blades can be evenly illuminated by the second light source module, thereby improving the light-emitting quality of the light-emitting fan. In addition, the light emission frequency of the first light source module and the second light source module can be set according to the rotation frequency of the light-emitting fan to create a special visual effect through visual persistence.

[0047] Please see Figures 1 to 3 . Figure 1 This is a three-dimensional schematic diagram of the light-emitting fan 10 according to the first embodiment of the present invention. Figure 2 for Figure 1 A schematic diagram of its breakdown. Figure 3 for Figure 1 A cross-sectional schematic diagram.

[0048] The light-emitting fan 10 in this embodiment includes a fan frame 100, a light-transmitting fan blade 200, an exterior component 300, a drive assembly 400, a first light source module 500, and a second light source module 600.

[0049] The light-transmitting fan blades 200 are made of, for example, highly transparent plastics, such as polystyrene (PS), acrylic (PMMA), or polycarbonate (PC). The light-transmitting fan blades 200 are rotatably mounted on the fan frame 100, allowing them to rotate relative to the fan frame 100. The light-transmitting fan blades 200 include a hub 210 and a plurality of blades 220. The hub 210 includes a cover plate 211 and an annular side plate 212. The annular side plate 212 is connected around the cover plate 211, such that the cover plate 211 and the annular side plate 212 together surround an accommodating space S. The cover plate 211 of the hub 210 has an outer surface 2111 and a groove 2112. The outer surface 2111 faces away from the accommodating space S, and the groove 2112 is recessed inward from the outer surface 2111. The annular side plate 212 has an annular side surface 2121, a back surface 2122, and a light-incident inclined surface 2123. The annular side surface 2121 faces away from the accommodating space S. The back surface 2122 faces the cover plate 211. The light-incident inclined surface 2123 is connected to the back surface 2122. The light-incident inclined surface 2123 faces away from and is not parallel to the annular side surface 2121. These blades 220 are connected to the annular side surface 2121 of the hub 210.

[0050] In this embodiment, the angle between the incident inclined surface 2123 and the annular side surface 2121 is, for example, 45 degrees, but is not limited thereto. In other embodiments, the angle between the incident inclined surface and the annular side surface can also be changed to any angle value between 0 and 90 degrees.

[0051] In this embodiment, the light-transmitting fan blade 200 may also include a noise reduction ring 230, which is connected to the side of the blades 220 away from the hub 210 to reduce the noise generated by the operation of the light-transmitting fan blade 200.

[0052] The outer part 300 is located in the groove 2112 and has a light-transmitting pattern structure 310. Specifically, the outer part 300 is made of, for example, a light-transmitting or light-guiding material, and an opaque paint is formed on a portion of the surface of the outer part 300, so that the surface of the outer part 300 not covered by the opaque paint forms the light-transmitting pattern structure 310. The light-transmitting pattern structure 310 is, for example, hexagonal.

[0053] The drive assembly 400 includes a stator 410 and a rotor 420. The stator 410 is, for example, an iron core with a wound coil fixed to the fan frame 100, and the rotor 420 is fixed to the hub 210 of the light-transmitting fan blade 200. The stator 410 is used to form a rotating magnetic field that drives the rotor 420, so that the rotor 420 drives the light-transmitting fan blade 200 to rotate.

[0054] The first light source module 500 is located in the accommodating space S and includes a first circuit board 510 and a plurality of vertical light-emitting diodes 520. These vertical light-emitting diodes 520 are disposed on the first circuit board 510, and one light-emitting surface 521 of these vertical light-emitting diodes 520 faces the cover plate 211 of the hub 210, so that the first light source module 500 generates light L1 which is emitted from the light-transmitting pattern structure 310.

[0055] The second light source module 600 is located in the accommodating space S and includes a second circuit board 610 and a plurality of side-emitting diodes 620. These side-emitting diodes 620 are disposed on the second circuit board 610, and one light-emitting surface 621 of each side-emitting diode 620 faces the incident light inclined surface 2123, allowing the second light source module 600 to generate light L2 to the incident light inclined surface 2123. In this way, some of the light is guided to the blade 220 through the interior of the annular side plate 212 of the hub 210, while another portion of the light directly passes through the annular side plate 212 of the hub 210 and illuminates the blade 220.

[0056] Please see Figure 4 . Figure 4 for Figure 2 A three-dimensional schematic diagram of the light-transmitting fan blades 200. In this embodiment, each of these blades 220 has a connecting side 221, and these connecting sides 221 of the blades 220 are respectively connected to the annular side surface 2121 of the hub 210. One end 2211 of the connecting side 221 is connected to the back surface 2122 of the annular side plate 212. That is, if the light-emitting fan 10 is laid flat with the outer appearance 300 facing upward, the lower end 2211 of the connecting side 221 of the blades 220 is at the same horizontal height as the back surface 2122 of the annular side plate 212.

[0057] Please see Figure 5 . Figure 5 for Figure 2 A planar schematic diagram of the light-transmitting fan blade 200 and the second light source module 600. In this embodiment, the emission angle θ of each lateral light-emitting diode 620 is, for example, 120 degrees, that is, the included angle B of the two emission boundaries B of the lateral light-emitting diode 620 is, for example, 120 degrees. However, the emission angle θ of the lateral light-emitting diode 620 is not intended to limit the invention. In other embodiments, the emission angle θ of the lateral light-emitting diode can also be any angle value between 1 and 360 degrees.

[0058] Since the light-emitting fan 10 is equipped with a first light source module 500 and a second light source module 600, the hub 210 of the light-transmitting fan blade 200 can be evenly illuminated by the first light source module 500, and the blades 220 of the light-transmitting fan blade 200 can be evenly illuminated by the second light source module 600, thereby improving the light emission quality of the light-emitting fan 10. In addition, the light emission frequencies of the first light source module 500 and the second light source module 600 can be set according to the rotation frequency of the light-emitting fan 10 to create a special visual effect through visual persistence.

[0059] In the above embodiment, the first light source module 500 adopts a forward-emitting vertical light-emitting diode 520, but it is not limited thereto. Please refer to Figure 6 . Figure 6 This is a cross-sectional schematic diagram of the light-emitting fan 10A according to the second embodiment of the present invention. The light-emitting fan 10A of this embodiment is similar to the light-emitting fan 10 of the above embodiment. Components with the same reference numerals have the same structure and connection relationship. The differences will be described below. The first light source module 500A of this embodiment is located in the accommodating space S and includes a first circuit board 510 and a plurality of side-emitting diodes 520A. These side-emitting diodes 520A are disposed on the first circuit board 510, and one light-emitting surface 521A of these side-emitting diodes 520A faces the annular side plate 212 of the hub 210, so that the first light source module 500A generates light L3 which is conducted from the annular side plate 212 to the light-transmitting pattern structure 310 and emitted.

[0060] According to the above embodiment of the light-emitting fan, since the light-emitting fan is equipped with a first light source module and a second light source module, the hub of the light-transmitting fan blades can be evenly illuminated by the first light source module, and the blades of the light-transmitting fan blades can be evenly illuminated by the second light source module, thereby improving the light-emitting quality of the light-emitting fan. In addition, the light emission frequency of the first light source module and the second light source module can be set according to the rotation frequency of the light-emitting fan to create a special visual effect through visual persistence.

[0061] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the scope defined in the appended claims.
