[0045] like Figures 1 to 4 As shown, an embodiment of the present application provides a fan light. The fan light includes a mounting assembly 10, a motor assembly 20, a lamp body assembly 30 and a fan blade assembly 40. The mounting assembly 10 has a first end 11 and a second end 12. The first end 11 of the mounting assembly 10 is fixedly mounted to the ceiling so that the lamp body assembly 30 and the fan blade assembly 40 are suspended downward from the ceiling. The motor assembly 20 includes a motor unit and a first connection end 211 and a second connection end 212 connected to both ends of the motor unit. The first connection end 211 is connected to the second end 12 of the mounting assembly 10, and the lamp body assembly 30 is mounted on the second connection end 212. The fan blade assembly 40 includes a mounting plate 41 and a plurality of fan blade components 42. The mounting plate 41 is connected to the motor assembly 20, and the plurality of fan blade components 42 are evenly distributed around the circumference of the motor assembly 20. Wherein, as Figures 2 to 10 As shown, the fan blade component 42 includes a connecting column 421 and a fan blade body 422. One end of the connecting column 421 away from the fan blade body 422 is connected to the mounting plate 41, and a transition structure 423 is provided at the circumferential connection position between the connecting column 421 and the fan blade body 422. Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 shown.

[0046] The fan lamp of the present application is fixedly installed on the ceiling through the installation component 10. The fan lamp has both lighting function and fanning and cooling function, wherein the lamp body component 30 emits light and illumination, and the motor component 20 drives the fan blade component 40 to rotate to fan and cool. In the fan lamp of the present application, the fan blade component 42 of the fan blade component 40 is designed with a connecting column 421 and a fan blade body 422 connected to the connecting column 421. The connecting column 421 is connected and fixed to the mounting plate 41, and the mounting plate 41 is connected to the second connecting end 212. In addition, a transition structure 423 is provided at the circumferential connection position between the connecting column 421 and the fan blade body 422, so that the circumferential connection position between the connecting column 421 and the fan blade body 422 is strengthened. In this way, in the process that the motor assembly 20 drives the mounting plate 41 to rotate and then drives the fan blade body 422 to rotate, the transition structure 423 can withstand the stress fatigue caused by the fan blade shaking on the circumferential connection position between the connecting column 421 and the fan blade body 422, so that the circumferential connection position between the connecting column 421 and the fan blade body 422 is not easy to crack, thereby improving the safety of the fan lamp and increasing the service life of the fan blade component 42.

[0047] In the fan lamp provided in this application, if Figures 1 to 5 As shown, the mounting assembly 10 includes a suspension rod 13 (a suspension rope may also be used to replace the suspension rod 13), the two ends of the suspension rod 13 are respectively the first end 11 and the second end 12 of the mounting assembly 10, and the two ends of the suspension rod 13 are respectively connected with a first adapter structure 14 and a second adapter structure 15, that is, the first end 11 of the mounting assembly 10 is fixedly mounted on the ceiling through the first adapter structure 14, and the first connecting end 211 is connected to the second end 12 of the mounting assembly 10 through the second adapter structure 15. In addition, the suspension rod 13 is sleeved with a first mounting cover 16 and a second mounting cover 17, the first mounting cover 16 is used to cover the first adapter structure 14, and the second mounting cover 17 is used to cover the motor assembly 20.

[0048] like Figure 2 and Figure 4 As shown, the lamp body assembly 30 includes a lamp housing 32, a diffuser plate 33 and an LED light source 34. The LED light source 34 is mounted on the lamp housing 32. The LED light source 34 of this embodiment adopts a spiral LED light strip, which is mounted on the inner wall of the lamp housing 32. The diffuser plate 33 is installed at the opening of the lamp housing 32. In addition, the fan lamp also includes a driver 35, which is installed on the first adapter structure 14 and covered by the first mounting cover 16 to block dust to a certain extent. The driver 35 is electrically connected to the LED light source 34 through wires, and the driver 35 controls the LED light source 34 to emit light, and the light is irradiated to the diffuser plate 33 and transmitted for illumination.

[0049] In order to make the connection column 421 and the fan blade body 422 smoothly connected through the transition structure 423, Figure 6 As shown, the side of the transition structure 423 away from the axis of the connecting column 421 is provided with an arc surface 424 that is recessed toward the axis of the connecting column 421. Specifically, the arc surface 424 is tangentially connected to the circumferential side surface of the connecting column 421, and the arc surface 424 is tangentially connected to the lower surface of the fan blade body 422. That is, the arc surface 424 is smoothly connected to the connecting column 421 and the fan blade body 422.

[0050] like Figure 6 , Figures 8 to 12 As shown, the arc surface 424 has a first transition position 425 and a second transition position 426, and the first transition position 425, the axis of the connecting column 421 and the second transition position 426 are located in the same plane. In the embodiment of the present application, the first transition position 425 is the position farthest from the mounting plate 41 in the circumferential contact position between the fan blade body 422 and the connecting column 421, and the second transition position 426 is the position closest to the mounting plate 41 in the circumferential contact position between the fan blade body 422 and the connecting column 421. In the process of the fan blade component 42 rotating with the mounting plate 41, the fan blade shakes, which then causes stress fatigue caused by the circumferential contact position between the fan blade body 422 and the connecting column 421. Moreover, in the circumferential contact position between the fan blade body 422 and the connecting column 421, the stress fatigue of the position farther from the mounting plate 41 is more serious, so the curvature radius of the arc surface 424 gradually decreases from the first transition position 425 to the second transition position 426. That is, the reinforcing effect of the transition structure 423 on the circumferential connection position between the blade body 422 and the connecting column 421 is adaptively designed according to the actual stress fatigue degree of the circumferential connection position between the blade body 422 and the connecting column 421, which can make the appearance of the transition structure 423 more beautiful while satisfying the reinforcing effect.

[0051] like Fig.10 and Fig.11 As shown, the curvature radius R1 of the arc surface 424 at the first transition position 425 ranges from 5.0 mm to 20.0 mm. That is, the minimum value of the curvature radius R1 of the arc surface 424 at the first transition position 425 is 5.0 mm, and the maximum value of the curvature radius R1 of the arc surface 424 at the first transition position 425 is 20.0 mm. Fig.10 and Fig.12 As shown, the curvature radius R2 of the arc-shaped surface 424 at the second transition position 426 ranges from 0.5 mm to 2.0 mm. That is, the minimum value of the curvature radius R2 of the arc-shaped surface 424 at the second transition position 426 is 0.5 mm, and the maximum value of the curvature radius R2 of the arc-shaped surface 424 at the second transition position 426 is 2.0 mm.

[0052] In the embodiment of the present application, the design of the curvature radius of the arc surface 424 of the transition structure 423 is specifically selected according to different sizes and the distribution of the actual stress fatigue degree at the circumferential connection position between the blade body 422 and the connecting column 421. Generally, the larger the overall size of the blade component 42, and the higher the actual stress fatigue degree at the circumferential connection position between the blade body 422 and the connecting column 421, the larger the curvature radius of the arc surface 424 of the transition structure 423.

[0053] Preferably, the connecting column 421, the fan blade body 422 and the transition structure 423 are integrally formed. In the embodiment of the present application, the fan blade component 42 is made of a plastic material. Preferably, the connecting column 421, the fan blade body 422 and the transition structure 423 are integrally formed by a mold injection molding process, and the processing efficiency is high.

[0054] like Figure 2 , Figure 4 and Figure 6 As shown, the connecting column 421 can be rotatably connected to the mounting plate 41. The fan blade component 42 can be rotated and stored relative to the mounting plate 41 when it is not needed to fan the air and cool down, which is convenient for storage. In addition, when the fan light is transported and moved, the fan blade component 42 can be rotated and stored relative to the mounting plate 41, so that the overall volume of the fan light is smaller and convenient for transportation and movement. Alternatively, when the user needs to use the fan light for fanning and cooling down, the fan blade component 42 can be rotated and extended relative to the mounting plate 41 and is in use.

[0055] Specifically, Figure 2 , Figure 4 and Figure 6 As shown, when the fan blade component 42 is assembled to the mounting plate 41, the damping washer 434 is first placed on the mounting plate 41, and then the end of the connecting column 421 away from the fan blade body 422 is abutted against the damping washer 434, and the gasket 433 is placed, and then the screw 431 passes through the gasket 433, the connecting column 421, the damping washer 434 and the mounting plate 41 in sequence. Then, the screw 431 is tightened with the nut 432 on the side of the mounting plate 41 away from the fan blade component 42, so as to stably clamp the mounting plate 41, and the fan blade component 42 is installed on the mounting plate 41. When the fan blade component 42 rotates relative to the mounting plate 41, the damping washer 434 will apply damping to the mounting plate 41 and the connecting column 421 at the same time, and when the fan blade body 422 rotates to the desired position relative to the mounting plate 41, the fan blade component 42 can be kept stable at the desired position, and the fan blade component 42 will not be randomly offset.

[0056] In an embodiment of the present application, the motor unit includes a stator portion 21 and a mover portion 22 rotatably mounted on the stator portion 21, and the stator portion 21 is inserted into the mover portion 22, that is, the motor unit is an external rotor motor. In addition, the first connection end 211 and the second connection end 212 are respectively connected to the two ends of the stator portion 21. In an embodiment of the present application, the mounting plate 41 is detachably connected to the end surface of the mover portion 22 away from the mounting assembly 10. Specifically, the mounting plate 41 is detachably connected to the second connection end 212 of the mover portion 22 by a flange connection, which not only has high assembly efficiency, but also is convenient for disassembly, and is convenient for repairing the fan light.

[0057] Along the axial direction of the stator portion 21, the projection of the mounting plate 41 is located within the projection of the lamp body assembly 30, that is, the projection area of ​​the mounting plate 41 is smaller than the projection area of ​​the lamp body assembly 30. Figures 1 to 6 As shown, the circumferential side wall of the lamp body assembly 30 is provided with a circumferential surrounding wall 31. Figure 1 and Figure 5 As shown, one end of the circumferential wall 31 extends toward the mounting plate 41 along the axial direction of the stator part 21, and the circumferential wall 31 surrounds the circumferential edge of the mounting plate 41, but there is no motion interference between the circumferential wall 31 and the fan blade member 42. In this way, when the fan light is hoisted on the ceiling, when the user looks up at the fan light, the circumferential edge of the mounting plate 41 is hidden by the circumferential wall 31, and the hidden design makes the user unable to see the mounting plate 41.

[0058] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
