[0027] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0028] In the description of the present application, the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0029] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, can also be detachable connection, can also be abutting connection or integral connection; for those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0030] In order to facilitate the understanding of the scheme provided by the embodiments of the present application, first, some terms and prior art related to the present scheme are briefly introduced.

[0031] In existing technologies, in order to prevent the light-emitting structure from occupying the inner space of the fan frame (see reference...), Figure 1 , Figure 1 The area within the dashed box refers to the fan frame, with the arrow pointing to the fan blades. The space inside the fan frame refers to the distance between the fan frame and the fan blades. This leads to the concept of the outer casing of the fan frame (i.e., the fan frame itself). Figure 1 The technical solution described (within the dashed box) involves a combination of LED beads and a light homogenizer. The light emitted from the LED beads illuminates the light homogenizer, causing the light to be evenly distributed across it. This uniform light output from the surface of the light homogenizer provides a decorative effect for the fan. Specifically, a light homogenizer is an optical element used to homogenize light distribution, aiming to make the light emitted from the light source more evenly distributed on its target surface. It adjusts the direction and intensity of light through diffusion, refraction, or reflection, thereby eliminating or reducing light spots, shadows, and other unevenness.

[0032] Further analysis of the technical problems existing in the above-mentioned prior art, with reference to Figure 2 According to the principle of light emission, without changing the material properties of the light homogenizer 103 itself, to make the light homogenizer 103 free of light spots 11 (light spots refer to dark areas that cannot be illuminated by the light of the light-emitting lamp beads 1021), and to make the light uniform and soft, it is necessary to increase the number of light-emitting lamp beads 1021 or increase the distance between the light-emitting lamp beads 1021 and the light homogenizer 103. Figure 2 The diagram shows a case where the light-emitting structure remains unchanged, but light spot 11 is present. The number of light-emitting LEDs 1021 is increased based on this structure (e.g., ...). Figure 3 As shown), spot 11 can be eliminated, but increasing the number of LED beads 1021 will increase costs. Increasing the distance between the LED beads 1021 and the diffuser 103 (e.g., ...) can also reduce costs. Figure 4 As shown, although it can also eliminate the light spot 11, this situation will increase the volume of the light-emitting structure. The overall external size of the fan is usually a standard specification. Increasing the volume of the light-emitting structure will force the size of the fan blades to be reduced, which will reduce the fan's heat dissipation capacity.

[0033] To address the aforementioned problems, this application improves the light-emitting structure, such as... Figure 5 As shown, by simply adding a low-cost reflector 101, it is possible to solve the problem of uneven emitted light caused by light spots 11 on the light homogenizer 103 without increasing the number of light-emitting lamp beads 1021 or the distance between the light-emitting lamp beads 1021 and the light homogenizer 103.

[0034] Figure 6 This is a schematic diagram of the structure of a light-emitting fan provided in an embodiment of this application.

[0035] likeFigure 6 As shown, the light-emitting fan comprises a light strip 102, a first light-reflecting piece 1011, a light-uniformizing body 103, and a fan body 104. In combination Figure 7 The light strip 102, the first light-reflecting piece 1011, and the light-uniformizing body 103 can adopt a ring structure, combined together to form a light chamber 105. The light strip 102 provides light, the first light-reflecting piece 1011 reflects the light, the light is mixed in the light chamber 105, the mixed light is incident on the light-uniformizing body 103, and then the light-uniformizing body 103 makes the mixed light uniform, and outputs uniform light to the outside of the light chamber 105, providing uniform and stable light effect for the fan body 104 around the center of the ring structure.

[0036] Referring to Figure 6 The light strip 102 comprises a light strip body and at least two light-emitting beads 1021. The light strip body adopts a ring structure and surrounds the fan body 104. The light-emitting beads 1021 are installed on the inner side of the light strip body and emit light through the top and side surfaces. Specifically, the light-emitting direction of the light-emitting beads 1021 is towards the side away from the light strip body. Figure 7 A cross-sectional view of the installed light-emitting fan is provided in this example, in combination Figure 7 The first light-reflecting piece 1011 adopts a ring structure and is arranged between the light strip body and the fan body 104, and is arranged on the side facing the light-emitting direction of the light-emitting beads 1021. The first light-reflecting piece 1011 is used to reflect the light emitted by the light-emitting beads 1021 through the reflecting surface.

[0037] In combination Figure 7 The light-uniformizing body 103 is arranged above the light strip 102. The light-uniformizing body 103, the light strip 102, and the first light-reflecting piece 1011 are combined to form the light chamber 105 and surround the fan body 104. Specifically, the light chamber 105 is used to mix the light emitted by the light-emitting beads 1021 and the light reflected by the first light-reflecting piece 1011. The light-uniformizing body 103 is used to uniformize the mixed light and output the light to the outside of the light chamber 105 through the surface, providing light effect for the fan body 104.

[0038] As can be seen from this example, by arranging the first light-reflecting piece 1011 in the combination of the light strip 102 and the light-uniformizing body 103, the first light-reflecting piece 1011 forms the light chamber 105 with the light strip 102 and the light-uniformizing body 103. Without increasing the number of light-emitting beads 1021 (saving cost) and without increasing the distance between the light-emitting beads 1021 and the light-uniformizing body 103 (saving light-emitting structure volume and avoiding fan size reduction), the light output to the outside is kept uniform, achieving better light-emitting effect.

[0039] In one example, as Figure 7As shown, the light mixing body 103 can output the uniform light to the outside of the light chamber 105 through the outer side surface 1031 thereof. Specifically, the light emitted by the light-emitting lamp bead 1021 is reflected by the first light-reflecting member 1011, and the light is mixed in the light chamber 105, and then the mixed light is incident on the light mixing body 103 opposite to the first light-reflecting member 1011. The light mixing body 103 homogenizes the light, and outputs the homogenized light to the outside of the light chamber 105 through the outer side surface 1031 thereof. In one example, as shown in FIG. 1B, the light-emitting fan further comprises a second light-reflecting member 1012. The second light-reflecting member 1012 is arranged below the light-emitting lamp bead 1021 and the first light-reflecting member 1011, and the first light-reflecting member 1011 and the second light-reflecting member 1012 are at a certain angle. Specifically, the light mixing body 103, the light strip 102, the first light-reflecting member 1011, and the second light-reflecting member 1012 form a light chamber 105. The light chamber 105 is used to mix the light emitted by the light-emitting lamp bead 1021 and the light reflected by the first light-reflecting member 1011 and the second light-reflecting member 1012, and then the light mixing body 103 outputs the mixed light to the outside of the light chamber 105. Figure 7 In one example, the angle between the first light-reflecting member 1011 and the second light-reflecting member 1012 is preferably 90 degrees, and can also be an acute angle, such as 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, etc., or an obtuse angle, such as 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees, 170 degrees, etc. The present application does not limit this.

[0040] In one example, as shown in FIG. 1B, the light-emitting fan further comprises a second light-reflecting member 1012. The second light-reflecting member 1012 is arranged below the light-emitting lamp bead 1021 and the first light-reflecting member 1011, and the first light-reflecting member 1011 and the second light-reflecting member 1012 are at a certain angle. Specifically, the light mixing body 103, the light strip 102, the first light-reflecting member 1011, and the second light-reflecting member 1012 form a light chamber 105. The light chamber 105 is used to mix the light emitted by the light-emitting lamp bead 1021 and the light reflected by the first light-reflecting member 1011 and the second light-reflecting member 1012, and then the light mixing body 103 outputs the mixed light to the outside of the light chamber 105.

[0041] In one example, as shown in FIG. 1B, the light-emitting fan further comprises a second light-reflecting member 1012. The second light-reflecting member 1012 is arranged below the light-emitting lamp bead 1021 and the first light-reflecting member 1011, and the first light-reflecting member 1011 and the second light-reflecting member 1012 are at a certain angle. Specifically, the light mixing body 103, the light strip 102, the first light-reflecting member 1011, and the second light-reflecting member 1012 form a light chamber 105. The light chamber 105 is used to mix the light emitted by the light-emitting lamp bead 1021 and the light reflected by the first light-reflecting member 1011 and the second light-reflecting member 1012, and then the light mixing body 103 outputs the mixed light to the outside of the light chamber 105. Figure 7

[0042] ​It is worth mentioning that when the light emitted by the light-emitting lamp beads 1021 is reflected by the first reflecting piece 1011 and the second reflecting piece 1012, the light is mixed by the light chamber 105, and the mixed light is incident on the light homogenizer 103, the light homogenizer 103 homogenizes the light, the top surface 1032 of the light homogenizer 103 is not transparent to light, or a light shielding piece is added outside the top surface 1032 of the light homogenizer 103, and only the outside surface 1031 of the light homogenizer 103 outputs the uniform light to the outside of the light chamber 105. Similarly, the outside surface 1031 of the light homogenizer 103 is not transparent to light, or a light shielding piece is added outside the outside surface 1031 of the light homogenizer 103, and only the top surface 1032 of the light homogenizer 103 outputs the uniform light to the outside of the light chamber 105, which is not limited by the present application.

[0043] As can be seen from the present example, by the light-emitting structure of the present solution, uniform double light effects can be achieved, i.e. light-emitting effects in the radial direction of the fan (the outside surface 1031 of the light homogenizer 103) and the axial direction (the top surface 1032 of the light homogenizer 103). In one example, the first reflecting piece 1011 and the second reflecting piece 1012 can be any one of a mirror, a light-reflecting paper, a light-reflecting film, etc. Specifically, the light-reflecting paper or the light-reflecting film can be pasted on a rigid plate to form the first reflecting piece 1011 and the second reflecting piece 1012, or the light-reflecting paper or the light-reflecting film can be designed to be rigid or semi-rigid first reflecting piece 1011 and second reflecting piece 1012, in addition, a light-transmitting plate with light-reflecting properties can also be used to design the first reflecting piece 1011 and the second reflecting piece 1012, which is not limited by the present application.

[0044] In one example, the light-emitting lamp beads 1021 can be any one or more of an LED lamp, a minLED lamp, an OLED lamp, etc.

[0045] In one example, referring back to Figure 6 , the light-emitting fan further comprises a housing 201, the center of the housing 201 is circular, the periphery is rectangular, and the reflecting piece 101, the lamp strip 102, the light homogenizer 103 and the fan body 104 are fixed through the center of the housing 201. Specifically, the fixing method can be one or more of threaded connection, clamping, riveting, bonding, welding, etc. For example, the reflecting piece 101, the lamp strip 102, the light homogenizer 103 and the fan body 104 are directly fixed on the housing 201 using screws and nuts. Alternatively, an upper housing and a lower housing can be provided, one of the housings is provided with a clamping groove, and the other housing is provided with a clamping buckle, the reflecting piece 101, the lamp strip 102, the light homogenizer 103 and the fan body 104 are fixed on the housing 201 by the clamping groove and the clamping buckle, or the housing 201 is further reinforced by screws and nuts.

[0046] In one example, referring back to Figure 6The side of the periphery of the shell 201 is provided with a decorative transparent window 202. Specifically, the decorative transparent window 202 can be composed of transparent or semi-transparent material, for transmitting the uniform light emitted from the external side 1031 of the uniform light body 103. The effect of the decorative transparent window 202 after installation can be referred to the installation effect diagram of the light-emitting fan Figure 1 .

[0047] In another example, the decorative transparent window 202 can have a designed pattern, which, in cooperation with the uniform light emitted from the uniform light body 103, achieves a decorative effect. In addition, the shape of the pattern is not limited in the present application.

[0048] In the description of the present specification, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0049] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
