[0023] An embodiment of the present application provides a ceiling fan.

[0024] Reference Figures 1 to 7 , a ceiling fan includes: a support rod 100, an electric device 200, a light-emitting component 300, a shell 400 and a fan blade 500.

[0025] Among them, the electric device 200 is arranged on the support rod 100; the light-emitting component 300 is arranged on the support rod 100; the shell 400 covers the electric device 200 and the light-emitting component 300; the fan blade 500 is driven to rotate by the electric device 200, and the fan blade 500 is provided with a light inlet 530, and the light inlet 530 faces the light-emitting component 300; the light emitted by the light-emitting component 300 enters the interior of the fan blade 500 from the light inlet 530, is reflected and conducted inside the fan blade 500, and is emitted through the blade surface 520 of the fan blade 500.

[0026] In this embodiment, the ceiling fan is supported and suspended by the support rod 100; the fan blade 500 is driven to rotate by the electric device 200 to blow air; the light-emitting component 300 emits light for illumination, and at the same time, the light emitted by the light-emitting component 300 enters the interior of the fan blade 500 from the light inlet 530, is reflected and conducted inside the fan blade 500, and is emitted through the blade surface 520 of the fan blade 500. The light is diffused by the reflection effect, and the light emitted from the blade surface 520 of the fan blade 500 can illuminate a larger range, and the light emitted from the blade surface 520 of the fan blade 500 is softer.

[0027] In some embodiments, a hanging member is provided at the upper end of the support rod 100. The ceiling fan is hung on the ceiling through the hanging member. The hanging member is provided with screw holes and screws, and is fixed to the ceiling through screw connection.

[0028] Reference Figure 6 The support rod 100 is a hollow rod, and the support rod 100 is provided with a wire channel for the power line to pass through.

[0029] Reference Figure 3 In some embodiments, the fan blade 500 includes an upper fan blade member 510, which is combined with a blade surface 520 to form a light channel 540. Preferably, the blade surface or a portion of the blade surface can be located below the upper fan blade member 510. The light inlet 530 is connected to the light channel 540. The light emitted by the light emitting element 300 enters the interior of the fan blade 500 through the light inlet 530 and is reflected and transmitted along the light channel 540 inside the fan blade 500.

[0030] It is understood that the upper fan blade 510 and the blade surface 520 can be two parts, and the upper fan blade 510 and the blade surface 520 are connected by snaps or screws to form the fan blade 500. Alternatively, the upper fan blade 510 and the blade surface 520 are integrally formed to form the fan blade 500 with the light channel 540 inside.

[0031] Reference Figures 2 to 5In some embodiments, the inner surface of the light channel 540 is provided with a plurality of reflective surfaces 511, and the plurality of reflective surfaces 511 reflect the light emitted by the light-emitting component 300 from the light inlet 530 and transmit it to the end of the fan blade 500 away from the light inlet 530. The reflective surface 511 can be formed by texturing or etching. The reflective surface 511 is made of a material with high reflectivity, such as an aluminum film. A plurality of reflective surfaces 511 are provided on the upper surface and the lower surface of the light channel 540, and some of the reflective surfaces 511 direct the light to other reflective surfaces 511. The light is reflected by the reflective surfaces 511 and propagated from one end of the fan blade 500 to the other end, so that light propagation occurs throughout the fan blade 500.

[0032] In some embodiments, the texture marking lines are lines that scatter from the edge of the semicircle to all sides, and the lines are intertwined to form polygons, wherein most of the polygons are prism-like quadrilaterals.

[0033] Because the light transmittance of the frosted surface is lower than that of the flat surface. In some embodiments, the upper and lower surfaces of the fan blade can be smooth surfaces, and the outer edge between the upper and lower surfaces can be frosted to reduce the light transmittance of the edge of the fan blade, thereby providing a softer look. In addition, decorative markings with etching or frosted textures can be set on the upper surface of the fan blade to provide a display aesthetic of light and dark intersections. Moreover, according to the pattern set on the fan blade 500, the texture or etching can display a refraction conduction effect.

[0034] In some embodiments, the fan blades 500 are formed as a whole with an irregular arc surface that conforms to aerodynamics, thereby improving the blowing effect of the fan blades 500. Similarly, the light channel 540 is an irregular arc surface with a shape substantially the same as the fan blades 500. The irregular arc surface is not a flat surface, which facilitates the reflection and transmission of light within the light channel 540.

[0035] In some embodiments, at least some of the internal structures of the fan blade 500 are made of a light-transmitting material, so that the light reflected in the light channel 540 can be emitted through the blade surface 520 made of the light-transmitting material. The light-transmitting material can be a material with high light transmittance such as PVC.

[0036] During the process of light being reflected and transmitted along the light channel 540 , a portion of the reflective surface 511 directs the light toward another reflective surface 511 , and another portion of the reflective surface 511 directs the light toward the leaf surface 520 made of a light-transmitting material.

[0037] The position, angle and area of ​​the reflective surface 511 and the position of the leaf surface 520 made of a light-transmitting material are set by a designed light conduction path.

[0038] Reference Figure 6 and Figure 7In some embodiments, the support rod 100 is connected to a first mounting member 310. The first mounting member 310 is in a pancake shape, and the support rod 100 is inserted through the first mounting member 310. A plurality of light-emitting members 300 are disposed on the outer surface of the first mounting member 310. The plurality of light-emitting members 300 are arranged along the circumference of the first mounting member 310 and around the support rod 100, so that the plurality of light-emitting members 300 can emit light in all directions.

[0039] It is understood that the first mounting member 310 is fixedly mounted on the support rod 100 and is located at the lower end of the support rod 100, and the light-emitting member 300 is fixedly mounted on the first mounting member 310. When the electric device 200 drives the fan blades 500 to rotate, the support rod 100 does not rotate, and the first mounting member 310 does not rotate, and the light-emitting member 300 on the first mounting member 310 also does not rotate.

[0040] The wires of the wire channel of the support rod 100 extend from the lower end of the support rod 100 into the first mounting member 310 and are connected to the light-emitting member 300 on the first mounting member 310, transmitting electrical energy to the light-emitting member 300 so that the light-emitting member 300 is powered on and emits light.

[0041] Reference Figure 7 The light-emitting element 300 can be a packaged LED lamp element in the form of a chip or lamp bead. Preferably, the first mounting member 310 is disc-shaped, and multiple SMD-packaged light-emitting elements 300 are soldered to a flexible circuit strip at a predetermined (e.g., uniform) spacing. This strip is then bent into a ring and placed around the circumference of the first mounting member 310. This structural configuration secures multiple light-emitting elements 300 to the first mounting member 310 while also providing a compact electrical connection.

[0042] Reference Figure 6 There are multiple fan blades 500, and the multiple fan blades 500 are spliced ​​together so that the light inlets 530 of the multiple fan blades 500 surround the first mounting member 310. The multiple fan blades 500 after splicing form a circle in the center, and the light inlet 530 is located on the side of the fan blade 500. The light inlets 530 of the multiple fan blades 500 also form a circle, and the first mounting member 310 is located in the circle. The multiple light-emitting members 300 are arranged along the circumference of the first mounting member 310 and are located on the same horizontal plane. The light inlets 530 of the multiple fan blades 500 after splicing are located on the same horizontal plane. The light-emitting members 300 and the light inlet 530 are located on the same horizontal plane, and the light-emitting direction of the light-emitting members 300 is toward the light inlet 530. When the electric device 200 drives the fan blade 500 to rotate, the light-emitting component 300 on the first mounting component 310 does not rotate, and the multiple light-emitting components 300 emit light in all directions. The multiple light inlets 530 formed in a circle remain circular when the fan blade 500 rotates. Therefore, during the rotation of the fan blade 500, the light emitted by the light-emitting component 300 can still enter the light channel 540 of the fan blade 500 from the light inlet 530.

[0043] Multiple light-emitting elements 300 are arranged along the circumference of the first mounting element 310 to emit light in all directions; light in different directions enters the light channel 540 of the fan blade 500 from different positions of the light inlet 530.

[0044] Reference Figure 1 In some embodiments, there are two fan blades 500, and the two fan blades 500 have the same shape. The light inlet 530 of the fan blade 500 is semicircular, and the light inlets 530 of the two fan blades 500 form a circle. The inner edges of the two sides of the light inlet 530 are straight lines, and the inner edges of the two fan blades 500 can be spliced ​​together accordingly.

[0045] The distance between the light emitting element 300 and the light inlet 530 should be set close to each other so that the light emitted by the light emitting element 300 can enter the light channel 540 through the light inlet 530 as much as possible. For example, in some embodiments, the distance between the light emitting element 300 and the light inlet 530 is set within 10 mm. Of course, in other embodiments, the distance between the light emitting element 300 and the light inlet 530 can be set to other values ​​based on actual production requirements.

[0046] Reference Figure 6 In some embodiments, the electric device 200 includes a rotor 220 and a stator 210, wherein the stator 210 is connected to the support rod 100, the rotor 220 is connected to the housing 400, and the housing 400 is connected to the fan blades 500. Preferably, the electric device 200 is implemented as a motor assembly.

[0047] The stator 210 surrounds the outside of the support rod 100 . The rotor 220 is disposed outside the stator 210 , and the housing 400 is disposed outside the rotor 220 .

[0048] When electric device 200 is powered, the coil windings of stator 210 generate a rotating magnetic field, which acts on rotor 220 to generate a magneto-electrodynamic torque, causing rotor 220 to rotate. Rotor 220 drives housing 400 and fan blades 500 connected to housing 400 to rotate. The rotation of fan blades 500 produces airflow.

[0049] A hole communicating with the wire channel is provided at the position of the support rod 100 corresponding to the electric device 200 ; the wires of the wire channel pass through the hole and connect to the electric device 200 , transmitting electrical energy to the electric device 200 to drive the electric device 200 to operate.

[0050] Reference Figure 6 In some embodiments, the housing 400 includes a first sub-housing 410 , the rotor 220 is connected to the first sub-housing 410 , and a first bearing is provided between the first sub-housing 410 and the support rod 100 .

[0051] The first sub-housing 410 is lid-shaped. The support rod 100 is inserted through the center of the upper surface of the first sub-housing 410. A hollow raised cover is provided in the center of the upper surface of the first sub-housing 410. A first bearing is disposed within the hollow raised cover. This first bearing enables the first sub-housing 410 to rotate smoothly around the support rod 100, driven by the electric device 200. The rotor 220 is disposed on the inner sidewall of the first sub-housing 410.

[0052] In some embodiments, the housing 400 includes a second sub-housing 420 , which is connected to the upper surface of the fan blade 500 . The second sub-housing 420 is connected to the first sub-housing 410 via a connecting piece 430 .

[0053] The second sub-shell 420 includes a first ring 421, a second ring 422, and a cylindrical sidewall 423. The outer edge of the first ring 421 is connected to the upper edge of the cylindrical sidewall 423, and the inner edge of the second ring 422 is connected to the lower edge of the cylindrical sidewall 423. The first ring 421 is provided with a screw hole, and the first ring 421 abuts the connecting piece 430; the second sub-shell 420 and the connecting piece 430 are connected by screws passing through the screw holes. The second ring 422 is provided with a screw hole, and the second ring 422 abuts the upper surface of the fan blade 500; the second sub-shell 420 and the fan blade 500 are connected by screws passing through the screw holes. The second sub-shell 420 is connected to the upper surface of the fan blade 500, so that the fan blade 500 can pass through the shell 400 and enter the interior of the shell 400. The light-emitting component 300 is arranged inside the shell 400, so that the light inlet 530 of the fan blade 500 can be close to the light-emitting component 300, so that the light emitted by the light-emitting component 300 can enter the light channel 540 from the light inlet 530 as much as possible, so that more light is emitted from the fan blade 500.

[0054] Reference Figure 6 In some embodiments, a second bearing 620 is disposed between the connecting piece 430 and the support rod 100. The connecting piece 430 is circular, and the support rod 100 is disposed at the center of the connecting piece 430. The second bearing 620 allows the connecting piece 430 and the second sub-housing 420 connected to the connecting piece 430 to rotate smoothly around the support rod 100.

[0055] The connecting piece 430 is equipped with three steps, each of which is annular and has a different height. The three steps gradually increase in height from the inside to the outside. A sleeve 434 extends downward from the inner edge of the first step 431. A second bearing 620 is disposed between the sleeve 434 and the support rod 100. The rotor 220 is supported on the second step 432. The second step 432 and the first sub-housing 410 form a space to accommodate the rotor 220. The third step 433 abuts the second ring 422 and is connected to the second ring 422 by screws.

[0056] The first sub-housing 410, the connecting piece 430 and the second sub-housing 420 are connected by screws. Of course, in other embodiments, they can also be connected by other means, such as welding.
