[0026] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] Referring to Figs. 1 to 4 The embodiment of the present application provides a lighting fan 10, which comprises a base 100, a fan assembly 200 and a lighting assembly 300. The fan assembly 200 comprises a driving member 210 and a light guide fan blade 220. The driving member 210 is connected to the base 100, and the fan blade 220 is connected to the output end of the driving member 210. The driving member 210 is used to drive the fan blade 220 to rotate. The lighting assembly 300 is arranged on the fan blade 220, and the light emitting direction of the lighting assembly 300 is towards the fan blade 220.

[0028] In the lighting fan 10 of the embodiment, the lighting assembly 300 is matched with the light guide fan blade 220. When the lighting assembly 300 is started, the light can be conducted and illuminated through the fan blade 220, without occupying extra space, so that the overall structure of the lighting fan 10 is compact.

[0029] Specifically, the fan blade 220 comprises a rotating shaft part 221 and a plurality of light guide blades 222. The rotating shaft part 221 is connected to the driving member 210, and the plurality of light guide blades 222 are connected to the rotating shaft part 221 and are arranged uniformly along the circumferential direction of the rotating shaft part 221. The lighting assembly 300 is connected to the rotating shaft part 221, and the lighting assembly 300 is used to emit light towards the light guide blades 222.

[0030] In the embodiment, the rotating shaft part 221 is coaxially connected with the driving part 210 and can be driven to rotate by the driving part 210. The light emitted by the lighting assembly 300 can be irradiated towards the fan blade 220 by starting the lighting assembly 300. At this time, since the fan blade 220 has the light guiding function, the fan blade 220 as a whole can realize the light emitting function, so as to realize the lighting function of the lighting fan 10. Compared with the traditional fan lamp, the lighting fan 10 of the embodiment can have a more compact structure and reduce the occupied space. Specifically, the driving part 210 can be a driving motor.

[0031] In an embodiment, the lighting assembly 300 includes a circuit board 310 and LED lamp beads 320. The circuit board 310 is connected to the rotating shaft part 221, and the LED lamp beads 320 are welded on the circuit board 310. The light emitting direction of the LED lamp beads 320 is towards the light guiding blade 222.

[0032] By adopting the lighting module form that the LED lamp beads 320 are welded on the circuit board 310, the lighting assembly 300 as a whole can have a lower cost. At the same time, the LED lamp beads 320 have a small amount of heat, and the overall reliability of the lighting fan 10 is also guaranteed.

[0033] Specifically, the rotating shaft part 221 is internally provided with a mounting groove 2211, and the mounting groove 2211 is arranged around the rotation axis of the rotating shaft part 221. The circuit board 310 is a flexible circuit board 310, which is accommodated in the mounting groove 2211 and arranged around the circumferential direction of the rotating shaft part 221.

[0034] In the embodiment, by arranging the lighting assembly 300 in the mounting groove 2211, the combined structure of the fan assembly 200 and the lighting assembly 300 can be more compact. At the same time, since the LED lamp beads 320 are arranged on the circuit board 310 and towards the fan blade 220, part of the light emitted by the LED lamp beads 320 can be reflected on the inner wall of the mounting groove 2211 and finally conducted to the fan blade 220, so as to make the overall illumination of the fan blade 220 more uniform.

[0035] Further, the number of the LED lamp beads 320 is multiple groups, and the multiple groups of LED lamp beads 320 are arranged along the circumferential direction of the rotating shaft part 221. Each group of LED lamp beads 320 corresponds to at least one light guiding blade 222.

[0036] Therefore, each light guide blade 222 corresponds to a group of LED lamp beads 320, so that the overall lighting effect of the fan blade 220 is more uniform; in an embodiment, the number of light guide blades 222 is five, and the number of LED lamp beads 320 is also five groups, and each of the five groups of LED lamp beads 320 corresponds to a light guide blade 222; in other embodiments, the light guide blades 222 and the LED lamp beads 320 can also be multiple and multiple groups, and can be three groups, four groups or more than five groups.

[0037] Further, the number of LED lamp beads 320 is multiple, and the multiple LED lamp beads 320 are arranged along the axial direction of the rotating shaft part 221.

[0038] In the embodiment, by arranging the multiple LED lamp beads 320 along the axial direction of the rotating shaft part 221, since the connection part of the light guide blade 222 and the rotating shaft part 221 is preferably arc-shaped, the light guide blade 222 can generate airflow only during the rotation of the fan blade 220, so that the illumination range of the multiple LED lamp beads 320 can fully cover the light guide blade 222, thereby further improving the lighting effect realized by the cooperation of the fan blade 220 and the lighting assembly 300.

[0039] In an embodiment, the fan blade 220 further comprises a mounting column 223 arranged in the mounting groove 2211, and the mounting column 223 is connected with the output end of the driving member 210; the outer wall of the column is arranged in the inner wall of the mounting groove 2211, and the circuit board 310 is arranged around the column.

[0040] By arranging the circuit board 310 on the mounting column 223, there is a gap between the surface of the circuit board 310 and the inner wall of the mounting groove 2211, so that the LED lamp beads 320 can be prevented from being squeezed when the lighting assembly 300 expands or shrinks due to heat or cold. Specifically, the circuit board 310 can be fixed on the mounting column 223 by adhesive. In addition, by arranging the lighting assembly 300 to be spaced from the inner wall of the mounting groove 2211, when the fan assembly 200 is started and airflow is generated, the lighting assembly 300 can also be driven to cool down.

[0041] Further, the light guide blade 222 is internally provided with a light guide dot 2221.

[0042] Therefore, when the light emitted by the LED lamp beads 320 irradiates on the light guide dot 2221, the light guide dot 2221 can reflect the light in different directions, further improving the light guide effect of the fan blade 220; specifically, the fan blade 220 can be prepared by injection molding, and at this time, the light guide dot 2221 can be suspended in the fan blade 220 during the processing, so that the light guide dot 2221 becomes an internal structure of the fan blade 220.
