Description

Technical Field

[0001] The present invention relates to the technical field of lighting fixtures, and in particular to a fan lamp. Background Art

[0002] A fan light is a commonly used household appliance, which is a combination of a fan and a lamp. The fan and the lamp can be controlled separately by a switch, so that the fan light has both the effect of lighting and the effect of fan blowing.

[0003] The fan lights currently on the market are improved from traditional fans, with lighting fixtures stacked on the basis of traditional fans. The structure of the fan and lighting fixtures basically adopts the same general design as the traditional structure. This general design will result in a larger overall size of the fan light, resulting in a larger space occupied by the fan light after installation, and is also not conducive to the transportation of the fan light. Summary of the invention

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] A fan lamp comprises a ceiling assembly, a suspension rod, a blade assembly, a light source assembly and a driver.

[0007] The blade assembly includes a base plate, a telescopic blade and a driving motor, wherein the telescopic blade is rotatably mounted on the base plate, the driving motor is connected to the base plate, one end of the suspension rod is connected to the ceiling assembly, the other end of the suspension rod is connected to the first end of the driving motor, the light source assembly is connected to the second end of the driving motor, and the light source assembly is located on a side of the blade assembly away from the ceiling assembly.

[0008] The driver is installed on the ceiling assembly, the blade assembly or the light source assembly, and is configured to be electrically connected to the driving motor and the light source assembly at the same time.

[0036] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] The following will, in conjunction with the drawings, detail the technical solutions disclosed in each embodiment of the present invention.

[0038] Please refer to Figures 1 to 11 Figures 1 to 11 , an embodiment of the present invention discloses a ceiling fan light, which includes a ceiling mounting assembly 100, a suspension rod 200, a blade assembly 300, a light source assembly 400, and a driver 500. The ceiling mounting assembly 100 is used to connect the ceiling fan light to an installation base (such as a roof), so as to install the ceiling fan light. The suspension rod 200 can connect the blade assembly 300 and the ceiling mounting assembly 100, that is, the length of the suspension rod 200 can be flexibly set. Optionally, the suspension rod 200 can adopt a multi-section structure, so that the user can adjust the length of the suspension rod 200 according to their own needs, thereby changing the installation height of the ceiling fan light. The blade assembly 300 can realize the blowing function, and the light source assembly 400 can provide illumination, so that the ceiling fan light has stronger functionality. The driver 500 can supply power to the blade assembly 300 and the light source assembly 400, so as to ensure the reliable operation of the blade assembly 300 and the light source assembly 400.

[0039]

[0039] The blade assembly 300 includes a base plate 310, telescopic blades 320, and a drive motor 330. The telescopic blades 320 are rotatably mounted on the base plate 310, and the drive motor 330 is connected to the base plate 310. Therefore, the drive motor 330 can drive the base plate 310 to rotate, and the telescopic blades 320 rotate relative to the base plate 310 under the action of centrifugal force, so as to realize the expansion and retraction of the telescopic blades 320. In an optional embodiment, when the telescopic blades 320 retract, the diameter R1 of the ceiling fan light can be 420-480 mm; when the telescopic blades 320 expand, the diameter R2 of the ceiling fan light can be 900-1200 mm. Optionally, the number of telescopic blades 320 can be at least two, and the telescopic blades 320 can be arranged along the circumference of the base plate 310, and the telescopic blades 320 can expand or retract synchronously. As the number of telescopic blades 320 increases, the heat dissipation effect of the ceiling fan light is better.

[0040] The ceiling mounting assembly 100 is connected to the blade assembly 300 through the suspension rod 200. Specifically, one end of the suspension rod 200 is connected to the ceiling mounting assembly 100, and the other end of the suspension rod 200 is connected to the first end of the drive motor 330. The light source assembly 400 is connected to the blade assembly 300. Specifically, the light source assembly 400 is connected to the second end of the drive motor 330, and the light source assembly 400 is located on the side of the blade assembly 300 away from the ceiling mounting assembly 100. In this solution, the blade assembly 300 and the light source assembly 400 are connected through the drive motor 330, and there is no need to additionally set up a connection structure to connect the blade assembly 300 and the light source assembly 400. Therefore, the number of components included in this ceiling fan light is less, the compactness of the entire ceiling fan light is higher, and the space occupied by it is smaller.

[0041] The driver 500 is installed in the ceiling-mounted component 100, the blade component 300, or the light source component 400. That is, the structure of the ceiling-mounted component 100, the blade component 300, or the light source component 400 can be utilized to install the driver 500, such that the space additionally occupied by the driver 500 is smaller, or even no additional space is occupied, thereby making the structure of the ceiling fan light more compact. In an alternative embodiment, the driver 500 is electrically connected to at least one of the blade component 300 and the light source component 400, thereby driving at least one of the blade component 300 and the light source component 400. When the driver 500 is electrically connected to the light source component 400, it can drive the light source component 400 to emit light, thereby realizing the lighting function of the ceiling fan light. When the driver 500 is electrically connected to the blade component 300, it can drive the telescopic blade 300 to expand and can also drive the entire blade component 300 to rotate, thereby realizing the blowing function of the ceiling fan light. When the driver 500 is electrically connected to both the blade component 300 and the light source component 400, it can drive the blade component 300 to rotate and the light source component 400 to emit light simultaneously, thereby realizing the blowing function and the lighting function of the ceiling fan light simultaneously.

[0042] Furthermore, the driver 500 can be configured to be electrically connected to both the drive motor 330 and the light source component 400 simultaneously. Optionally, the driver 500 is electrically connected to the drive motor 330 through the first electrical connector 810, and the driver 500 is electrically connected to the light source component 400 through the second electrical connector 820. In addition, the driver 500 can be connected to the mains power through the mains electrical connector 830. Here, the first electrical connector 810, the second electrical connector 820, and the mains electrical connector 830 can all be selected as wires. At this time, the driver 500 can be integrally arranged. The same driver 500 can supply power to both the drive motor 330 and the light source component 400 simultaneously, and the number of required drivers 500 is naturally reduced. Optionally, the driver 500 can be set to one. When the power consumption of the ceiling fan light is relatively large, two or even more drivers 500 can also be set, and each driver 500 is configured to be electrically connected to both the drive motor 330 and the light source component 400 simultaneously.

[0043] In the ceiling fan light disclosed in the embodiment of the present invention, the drive motor 330 of the blade component 300 and the light source component 400 can be electrically connected to the same driver 500, such that the blade component 300 and the light source component 400 can be driven by the same driver 500. Compared with the manner in which the blade component 300 and the light source component 400 are driven by their respective drivers, the number of components of the ceiling fan light disclosed in the embodiment of the present invention is reduced. Therefore, the space occupied by the ceiling fan light is smaller, and it is also convenient for the transportation of the ceiling fan light.

[0044] In an alternative embodiment, the ceiling-mounted assembly 100 includes a ceiling-mounted box 110 which has an installation cavity 111, and the driver 500 is installed in the installation cavity 111. At this time, the driver 500 is installed by using the installation cavity 111 in the ceiling-mounted box 110, and the driver 500 basically does not occupy extra space, thus making the structure of the fan light more compact.

[0045] Furthermore, the ceiling-mounted assembly 100 further includes a hanging bracket 120 installed in the installation cavity 111. The hanging bracket 120 is installed in the installation cavity 111, and the ceiling-mounted box 110 is fixedly connected to the hanging bracket 120. The ceiling-mounted box 110 can be installed on the installation base through the hanging bracket 120. The hanging bracket 120 can adopt a U-shaped structure. The hanging bracket 120 is provided with a connecting portion 121 which has a connecting hole and a first spherical surface. The suspender 200 has a second spherical surface. One end of the suspender 200 passes through the connecting hole, and the first spherical surface fits with the second spherical surface. Through the cooperation of the first spherical surface and the second spherical surface, the position of the suspender 200 relative to the hanging bracket 120 can be changed, thus facilitating the installation of the fan light.

[0046] The driver 500 is installed between the side surface of the hanging bracket 120 and the inner wall of the ceiling-mounted box 110. That is to say, there is a gap between the side surface of the hanging bracket 120 and the inner wall of the ceiling-mounted box 110, and the driver 500 can be arranged by using this gap, so as to make full use of the installation cavity in the ceiling-mounted box 110 to install the driver 500, making the structure of the fan light more compact.

[0047] Optionally, the drive motor 330 may include a motor housing 331, a stator module 332, a rotor module 333, a first bearing 334 and a second bearing 335. The motor housing 331 may include an upper cover 331a and a lower cover 331b, which are detachably connected to form a space for accommodating the stator module 332 and the rotor module 333. The stator module 332 is cooperated with the upper cover 331a through the first bearing 334 and is cooperated with the lower cover 331b through the second bearing 335. Optionally, as Figure 7 shown, the outer diameter R3 of the drive motor 330 may be 110 - 130 mm, preferably about 120 mm, and its height h may be 40 - 50 mm, preferably about 45 mm. The structure of such a drive motor 330 is more compact and it occupies less space.

[0048] Both ends of the above-mentioned stator module 332 are respectively connected to the suspension rod 200 and the light source assembly 400, the rotor module 333 is connected to the housing 331, and the housing 331 is connected to the substrate 310. When the drive motor 330 is powered on, a force is generated between the stator module 332 and the rotor module 333. The stator module 332 remains stationary, and the rotor module 333 can rotate relative to the stator module 332, thereby driving the housing 331 to rotate. The housing 331 then drives the substrate 310 to rotate, so as to realize the deployment of the telescopic blades 320. In this solution, the housing 331 drives the substrate 310 to rotate. When the housing 331 rotates, it is more stable and has a stronger ability to bear the acting force. Therefore, the transmission efficiency of this drive motor 330 is higher and its service life is longer.

[0049] The stator module 332 is provided with a first through hole, and the suspension rod 200 is provided with a second through hole. The first electrical connector 810 passes through the second through hole and is electrically connected to the stator module 332 and the rotor module 333. The second electrical connector 820 sequentially passes through the second through hole and the first through hole and is electrically connected to the light source assembly 400. After the first through hole and the second through hole are provided, the stator module 332 and the suspension rod 200 can avoid the first electrical connector 810 and the second electrical connector 820, so as to facilitate the electrical connection between the driver 500 and the drive motor 330 and the light source assembly 400. At the same time, the first through hole and the second through hole can appropriately limit the positions of the first electrical connector 810 and the second electrical connector 820, so that the first electrical connector 810 and the second electrical connector 820 are not easily interfered with other components, making the ceiling fan light operate more reliably.

[0050] In order to protect the drive motor 330, the blade assembly 300 may further include a motor cover 370. The motor cover 370 covers the outside of the housing 331, and the motor cover 370 can cover the drive motor 330 to protect the drive motor 330. Further, the blade assembly 300 may further include a connector 380. The connector 380 is connected to the motor cover 370. One end of the connector 380 is inserted into the suspension rod 200, and one end of the stator module 332 extends into the connector 380. In this embodiment, the connector 380 connects the suspension rod 200 and the stator module 332 together. Since the connector 380 and the suspension rod 200 are connected by insertion, this method is more convenient for operation. At the same time, the connector 380 and the suspension rod 200 are detachable, which is convenient for the maintenance of the ceiling fan light.

[0051] The above-mentioned connecting member 380 and the motor cover 370 can adopt an integral structure. However, for the convenience of installation and maintenance of the ceiling fan light, a third through hole 371 can be provided on the motor cover 370. The connecting member 380 includes a positioning plate 381 and a cylindrical body 382. The positioning plate 381 can be in positioning cooperation with the motor cover 370. One end of the cylindrical body 382 is connected to the positioning plate 381, and the other end of the cylindrical body 382 passes through the third through hole 371 and is inserted into the suspension rod 200. This structure can not only ensure the reliable connection between the connecting member 380 and the motor cover 370, but also make the two detachable, thus facilitating the installation and maintenance of the ceiling fan light.

[0052] To improve the connection strength between the suspension rod 200 and the connecting member 380, one end of the suspension rod 200 is threadedly connected to the cylindrical body 382. The cylindrical body 382 is provided with a first insertion hole, and the suspension rod 200 is provided with a second insertion hole. A pin is inserted at the first insertion hole and the second insertion hole. After adopting this connection method, at least one of the suspension rod 200 and the connecting member 380 can be rotated to make the two in threaded cooperation and gradually inserted and connected. This connection method more reliably connects the suspension rod 200 and the connecting member 380 through insertion and threaded cooperation. At the same time, when the suspension rod 200 and the connecting member 380 are rotated to a predetermined position, the first insertion hole and the second insertion hole are aligned, and the pin is inserted into the first insertion hole and the second insertion hole. The pin can assist in restricting the relative rotation between the suspension rod 200 and the connecting member 380, so that even when the blade assembly 300 of the ceiling fan light rotates, it is not easy to have the situation that the suspension rod 200 and the connecting member 380 rotate relative to each other and become loose, thereby making the structural strength of the ceiling fan light higher.

[0053] The above-mentioned connecting member 380 can be in an exposed state, and at this time the pin is also in an exposed state. Such a setting is not only not beautiful, but also there is a risk that the pin is easily disassembled by mistake. Therefore, to solve this problem, the ceiling fan light further includes a covering cover 600. The covering cover 600 covers the outside of the pin. The covering cover 600 can separate the pin and the connecting member 380 from the external environment, thereby improving the aesthetics of the ceiling fan light. At the same time, when the user needs to disassemble the suspension rod 200 and the connecting member 380, the covering cover 600 must be removed first, thereby reducing the risk of the pin being disassembled by mistake. Optionally, to simplify the disassembly and assembly operation of the covering cover 600, the covering cover 600 can be sleeved on the outside of the suspension rod 200. It can move flexibly relative to the covering cover 600, and it can cover structures such as the pin under the action of its own gravity.

[0054] In a further embodiment, the covering cover 600 is provided with a fourth through hole 610, and an elastic ring 620 is provided at the fourth through hole 610. The elastic ring 620 surrounds the suspension rod 200. The elastic ring 620 here can fill the gap between the suspension rod 200 and the fourth through hole 610, and the elastic ring 620 can be deformed when stressed. The elastic ring 620 can reduce the gap between the suspension rod 200 and the fourth through hole 610. At the same time, when the elastic ring 620 contacts the suspension rod 200, the elastic ring 620 is deformed, so as to fit more closely with the suspension rod 200, further improving the sealing effect. Moreover, the elastic ring 620 can be deformed when stressed, so as to achieve buffering and prevent situations such as loud noise and short component life caused by rigid collision of components of the ceiling fan light.

[0055] In an alternative embodiment, the ceiling fan light further includes a positioning member 700. The light source assembly 400 includes a chassis 410, a light source board 420 and a light-transmitting mask 430. The chassis 410 and the light-transmitting mask 430 are connected to form a first optical cavity. The light source board 420 is installed in the first optical cavity. A plurality of light-emitting modules 440 are arranged at intervals on the light source board 420. The light-emitting module 440 includes a light-emitting unit and a light distribution element, and the light distribution element covers the outside of the light-emitting unit. The second end of the drive motor 330 extends into the first optical cavity. The positioning member 700 is installed at the second end of the drive motor 330 and is located in the first optical cavity. The positioning member 700 is in positioning cooperation with the chassis 410. In this embodiment, the connection between the drive motor 330 and the light source assembly 400 can be realized through the positioning member 700. The structure of this connection method is simpler, and at the same time, the connection operation between the drive motor 330 and the light source assembly 400 can be simplified.

[0056] Optionally, the positioning member 700 can be a nut, and the positioning member 700 can be in threaded cooperation with the second end of the drive motor 330, so as to further simplify the connection operation between the drive motor 330 and the light source assembly 400.

[0057] Optionally, when the driver 500 is installed on the light source assembly 400, the driver 500 can be further installed in the above-mentioned first optical cavity. The space of the first optical cavity is relatively large, so it is more convenient to arrange the driver 500. At the same time, if the driver 500 needs to be disassembled, only the light-transmitting mask 430 needs to be opened, and the driver 500 can be directly seen. Therefore, this structure is more convenient for maintaining the driver 500.

[0058] Both the above-mentioned driver 500 and the light source board 420 are located in the first optical cavity and are both arranged adjacent to the chassis 410. Therefore, interference is likely to occur between the two in terms of structure. In one embodiment, the driver 500 can be stacked on the light source board 420. However, this structure will cause the part of the light source board 420 blocked by the driver 500 to be unable to work, resulting in structural waste. At the same time, it will also cause a larger space to be occupied jointly by the light source board 420 and the driver 500. Based on this, in another embodiment, the light source board 420 is an annular board with an inner hole, and at least a part of the driver 500 is located in this inner hole. In this embodiment, the light source board 420 can avoid the driver 500, enabling all structures of the light source board 420 to be used. At the same time, the driver 500 can be installed using the space occupied by the light source board 420, thus making the structure of the ceiling fan light more compact.

[0059] The telescopic blades 320 of the blade assembly 300 can be deployed or retracted. When the telescopic blades 320 are in the retracted state, the telescopic blades 320 do not work, and the space occupied by the blade assembly 300 at this time will affect the aesthetics of the entire ceiling fan light. Based on this, the direction parallel to the hanging rod 200 is defined as the first direction. When the telescopic blades 320 are in the retracted state, the positive projection of the telescopic blades 320 in the first direction is located within the positive projection of the chassis 410 in the first direction. That is to say, in this retracted state, the edges of the telescopic blades 320 do not extend beyond the edges of the chassis 410, so that the space occupied by the telescopic blades 320 in this state is minimized, thereby optimizing the structural compactness of the ceiling fan light.

[0060] In an alternative embodiment, the light source assembly 400 further includes a mounting disk 450. The mounting disk 450 is arranged between the blade assembly 300 and the chassis 410. The second end of the drive motor 330 passes through the mounting disk 450, and the mounting disk 450 abuts against the chassis 410. Since the blade assembly 300 rotates during operation while the light source assembly 400 is stationary, the mounting disk 450 can better separate the blade assembly 300 and the light source assembly 400, and at the same time prevent the blade assembly 300 from driving the light source assembly 400 to rotate, achieving the purpose of improving the reliability of the ceiling fan light during operation. In addition, the mounting disk 450 abuts against the chassis 410, which can better limit the shaking of the chassis 410 and prevent the chassis 410 from experiencing slight swings due to the movement of the blade assembly 300, thereby improving the user experience when using the ceiling fan light.

[0061] To improve the appearance quality of the ceiling fan light, the light source assembly 400 further includes a decorative ring 460. The decorative ring 460 is arranged on the outer peripheral surface of the light-transmitting mask 430. The structural parameters such as the material and shape of the decorative ring 460 can be designed according to the user's preferences, thereby improving the overall appearance quality of the ceiling fan light.

[0062] As described above, the number of the telescopic blades 320 can be at least two. When the substrate 310 rotates, each telescopic blade 320 is affected by the centrifugal force and unfolds. However, due to factors such as machining errors and assembly errors, there may be differences in the unfolding amplitude and speed of each telescopic blade 320, which results in a large contingency in the heat dissipation effect of the blade assembly 300. Based on this, in an optional embodiment, the blade assembly 300 further includes a synchronizing member 340 and a mounting seat 350. The synchronizing member 340 is rotatably mounted on the substrate 310, and the rotation center of the synchronizing member 340 coincides with the rotation center of the substrate 310. The plurality of telescopic blades 320 are rotatably mounted on the substrate 310 through a plurality of mounting seats 350. The synchronizing member 340 is provided with a plurality of sliding grooves 341, and the mounting seat 350 is provided with a protruding portion. The protruding portions of each mounting seat 350 are slidably engaged with the corresponding sliding grooves 341 one by one. When the substrate 310 rotates, the synchronizing member 340 rotates accordingly. Under the action of the plurality of sliding grooves 341 and the plurality of protruding portions, each telescopic blade 320 can be unfolded synchronously, thereby overcoming the influence of factors such as machining errors and assembly errors, so that the heat dissipation effect of the blade assembly 300 can more reliably approach the design value, thereby improving its blowing effect. At the same time, this structure can also make the acting force of the fan light more evenly distributed, preventing the fan light from shaking due to uneven distribution of the acting force.

[0063] In order to make the telescopic blade 320 retract more reliably, the blade assembly 300 may further include a torsion spring 360. One end of the torsion spring 360 is connected to the substrate 310, and the other end of the torsion spring 360 is connected to the telescopic blade 320. Specifically, the torsion spring 360 can be mounted on the mounting seat 350. When the telescopic blade 320 unfolds, the torsion spring 360 is deformed by the acting force from the telescopic blade 320. When the blade assembly 300 finishes working, the centrifugal force acting on it disappears, and the acting force of the telescopic blade 320 on the torsion spring 360 also disappears. The torsion spring 360 can then recover its deformation, thereby applying a reaction force to the telescopic blade 320, causing the telescopic blade 320 to retract relative to the substrate 310 until the telescopic blade 320 retracts in place. The torsion spring 360 occupies a small space, so it is more conducive to realizing the compact design of the fan light.

[0064] Optionally, the driver 500 includes a circuit board. The circuit board is provided with an input end, a first output end and a second output end. The first output end is electrically connected to the drive motor 330, and the second output end is electrically connected to the light source assembly 400. The circuit board here can realize the control of the fan light. That is to say, the drive part and the control part of the fan light can be integrally designed, making the structure of the fan light more compact.

[0065] In other embodiments, such as Figures 12 to 15As shown, the light source assembly 400 may include a chassis 410 and a directional lighting module 470. The chassis 410 may provide a mounting base for the directional lighting module 470, the blade assembly 300, or other components of the ceiling fan light. The directional lighting module 470 is mounted on the chassis 410. When the directional lighting module 470 is driven, it can emit light for illumination, enabling the ceiling fan light to have an illumination function. Here, the illumination area of the directional lighting module 470 is relatively concentrated, so it can illuminate the area that needs to be highlighted.

[0066] In the ceiling fan light disclosed in the embodiment of the present invention, the light source assembly 400 includes a directional lighting module 470. The directional lighting module 470 can perform directional lighting on the key area. The user can control the working state of the directional lighting module 470 according to actual needs, so as to meet their own lighting requirements. It can be seen that the ceiling fan light can perform directional lighting on the key area, making the lighting effect of the ceiling fan light better.

[0067] In an alternative embodiment, the directional lighting module 470 includes a first light source board 471 and at least one first light-emitting module 472. The first light source board 471 is mounted on the chassis 410, and the first light-emitting module 472 is disposed on the first light source board 471. The first light-emitting module 472 includes a first light-emitting unit 472a and a first light distribution element 472b. The first light distribution element 472b covers the outside of the first light-emitting unit 472a. The first light-emitting unit 472a can emit light. The light emitted by the first light-emitting unit 472a enters the first light distribution element 472b, and the first light distribution element 472b can change the propagation direction of the light to achieve light distribution, thereby adjusting the light output angle of the directional lighting module 470 to obtain the desired lighting effect.

[0068] Optionally, the number of the first light-emitting modules 472 can be one or at least two. When the number of the first light-emitting modules 472 is at least two, the first light-emitting modules 472 can be arranged at intervals, so that the emitted light is more uniform, thereby improving the lighting effect of the ceiling fan light.

[0069] Furthermore, the first light distribution element 472b can be a lens, such as a convex lens or a concave lens, or a combination of a convex lens and a concave lens. The first light distribution element 472b can converge the light, making the light converge in a relatively small area, thereby enhancing the lighting effect of the directional lighting module 470.

[0070] To avoid the problem of glare during the illumination of the directional lighting module 470, in an alternative embodiment, the directional lighting module 470 further includes an anti-glare mask 473, and the anti-glare mask 473 is connected to the first light distribution element 472b. The anti-glare mask 473 here can further adjust the propagation direction of the light, thereby achieving the purpose of anti-glare and improving the comfort of users when using the ceiling fan light. For example, the light emitted by the first light-emitting unit 472a enters the first light distribution element 472b. After the first light distribution element 472b redistributes the light, a part of the light within the light-emitting range irradiates the illumination area of the directional lighting module 470, and another part of the light not within the light-emitting range can be absorbed by the anti-glare mask 473. Therefore, when the user is in an area outside the light-emitting range, the brightness difference between the illumination area of the directional lighting module 470 and the area outside the illumination area is small, and the human eye will not be directly irradiated by the strong light of the first light-emitting unit 472a, thereby avoiding the user from feeling dazzled and uncomfortable. At the same time, the connection between the anti-glare mask 473 and the first light distribution element 472b can also improve the aesthetics of the directional lighting module 470.

[0071] Further, the anti-glare mask 473 can be a conical mask, and both ends of the anti-glare mask 473 are open ends. The taper of such a conical mask can be more accurately controlled, so it is convenient to adjust the structural parameters of the anti-glare mask 473, which is beneficial to improving the anti-glare effect of the anti-glare mask 473. In addition, the conical mask is easier to process, making the anti-glare mask 473 more convenient to form, and its cost is lower.

[0072] The optical parameters of the anti-glare mask 473 can be flexibly set. To improve the anti-glare effect of the anti-glare mask 473, the cone angle of the anti-glare mask 473 can be made less than 37°. This setting method can further reduce the irradiation range of the light not within the light-emitting range, thereby reducing the impact of glare on the user and achieving the purpose of improving the anti-glare effect.

[0073] In an alternative embodiment, the color rendering index of the first light-emitting unit 472a is greater than or equal to 90. When the color rendering index of the first light-emitting unit 472a is greater than or equal to 90, the light emitted by the first light-emitting unit 472a has a higher color restoration degree for the irradiated object. Under the irradiation of the light emitted by the first light-emitting unit 472a, the color of the object is closer to its true color, thereby improving the illumination effect of the directional lighting module 470.

[0074] The usage scenarios of the fan light are diverse. For example, it can be used for lighting in areas such as the dining table area, coffee table area, sofa area, bar area, etc. To meet different usage requirements of users, in an alternative embodiment, the light source assembly 400 further includes a floodlighting module 480. The floodlighting module 480 is installed on the chassis 410, and both the directional lighting module 470 and the floodlighting module 480 are located on the same side of the chassis 410. The floodlighting module 480 here can illuminate a relatively large area, thereby achieving the effect of floodlighting. The directional lighting module 470 and the floodlighting module 480 can be used separately or together. When the user needs to perform directional lighting on a key area, the directional lighting module 470 can be used; when the user needs to perform ambient lighting on a large area, the floodlighting module 480 can be used. It can be seen that in this embodiment, both the directional lighting module 470 and the floodlighting module 480 are provided, enabling the fan light to have at least two lighting modes. The user can change the working states of the directional lighting module 470 and the floodlighting module 480 according to different usage requirements, thereby enhancing the lighting effect of the fan light.

[0075] Further, the light-emitting angle of the above-mentioned directional lighting module 470 is smaller than that of the floodlighting module 480, so that the light-emitting range of the directional lighting module 470 is smaller than that of the floodlighting module 480. Therefore, the directional lighting module 470 can form a relatively small lighting area to achieve directional lighting, while the floodlighting module 480 can form a relatively large lighting area to achieve floodlighting. It should be noted that the difference between the light-emitting angle of the directional lighting module 470 and the light-emitting angle of the floodlighting module 480 can be flexibly designed according to the usage requirements of the fan light, and the embodiments of the present invention do not limit this.

[0076] In an alternative embodiment, the floodlighting module 480 includes a second light source board 481, a light homogenizing mask 483, and at least one second light-emitting module 482. The light homogenizing mask 483 is connected to the chassis 410, and the two form a second optical cavity. The second light source board 481 is installed in the second optical cavity. The second light-emitting module 482 is disposed on the second light source board 481. The second light-emitting module 482 includes a second light-emitting unit and a second light distribution element. The second light distribution element covers the outside of the second light-emitting unit. The second light-emitting unit can emit light. The light emitted by the second light-emitting unit enters the second light distribution element, and the second light distribution element diverges the light, thereby improving the uniformity during the lighting of the floodlighting module 480. Further, after the light emitted by the second light-emitting unit enters the second light distribution element and is redistributed, the light enters the light homogenizing mask 483. The light homogenizing mask 483 can further improve the divergence degree of the light, thereby improving the uniformity during the lighting of the floodlighting module 480, and thus enhancing the lighting effect of the floodlighting module 480.

[0077] In an alternative embodiment, both the first light source board 471 and the second light source board 481 are straight strip-shaped boards, and the extending direction of the first light source board 471 is parallel to the extending direction of the second light source board 481; or both the first light source board 471 and the second light source board 481 are arc-shaped boards, and the centers of the circles where the first light source board 471 is located coincide with the centers of the circles where the second light source board 481 is located. After adopting these two structures, whether the directional lighting module 470 and the floodlighting module 480 work independently or the directional lighting module 470 and the floodlighting module 480 work simultaneously, more regular lighting areas can be generated; at the same time, the shape of the lighting area of the directional lighting module 470 is basically the same as the shape of the lighting area of the floodlighting module 480, so that the brightness of the overall lighting area of the ceiling fan light changes regularly, which can bring a better visual experience to users. In addition, when both the first light source board 471 and the second light source board 481 are straight strip-shaped boards or arc-shaped boards, the ceiling fan light has a higher structural compactness, a simpler processing technology, and a lower cost.

[0078] In an alternative embodiment, the number of the floodlighting modules 480 is at least two, and at least one directional lighting module 470 is provided between adjacent floodlighting modules 480. When at least one directional lighting module 470 is provided between adjacent floodlighting modules 480, the lighting area of the directional lighting module 470 is surrounded by the lighting area of the floodlighting module 480, and the lighting area of the directional lighting module 470 is located in the middle of the lighting area of the floodlighting module 480, so that the lighting area of the ceiling fan light has symmetry, thereby improving the lighting effect of the ceiling fan light.

[0079] In other embodiments, the light source assembly 400 further includes a face frame 490, the face frame 490 is connected to the chassis 410, the face frame 490 is provided with a first receiving hole 491 and a second receiving hole 492, at least a part of the floodlighting module 480 is located in the first receiving hole 491, and at least a part of the directional lighting module 470 is located in the second receiving hole 492. After adopting this structure, the face frame 490 can moderately separate and block the directional lighting module 470 and the floodlighting module 480, so that the lighting areas of the floodlighting module 480 and the directional lighting module 470 do not interfere with each other, which is beneficial to the ceiling fan light to realize the division of the key lighting area and the ambient lighting area, thereby improving the lighting effect of the ceiling fan light. In addition, at least a part of the floodlighting module 480 is located in the first receiving hole 491, and at least a part of the directional lighting module 470 is located in the second receiving hole 492, which can prevent dust from entering the floodlighting module 480 and the directional lighting module 470, and is beneficial to the more stable operation of the floodlighting module 480 and the directional lighting module 470.

[0080] Further, at least two second receiving holes 492 are provided between adjacent first receiving holes 491, and at least two directional lighting modules 470 are respectively mounted at the at least two second receiving holes 492. In this embodiment, each directional lighting module 470 is mounted at a different second receiving hole 492, so that the lighting areas of the directional lighting modules 470 are less likely to interfere with each other, which is beneficial for the directional lighting modules 470 to perform directional lighting on key areas. At the same time, when the size of the directional lighting area is fixed, by mounting at least two directional lighting modules 470 through at least two second receiving holes 492, the size of a single second receiving hole 492 can be appropriately reduced, thereby ensuring the structural strength of the face frame 490.

[0081] In an alternative embodiment, the ceiling fan light further includes a controller, which is electrically connected to the directional lighting module 470 and the floodlighting module 480 respectively. The controller is used to control the working states of the directional lighting module 470 and the floodlighting module 480. When the controller controls one of the directional lighting module 470 and the floodlighting module 480 to work, the ceiling fan light can separately achieve key lighting or ambient lighting for the space; when the controller controls the directional lighting module 470 and the floodlighting module 480 to work together, the ceiling fan light can simultaneously achieve key lighting and ambient lighting for the space. By controlling the working states of the directional lighting module 470 and the floodlighting module 480 through the controller, the lighting effect of the ceiling fan light is improved. Further, the ceiling fan light can be configured with a remote controller, which can perform wireless data transmission with the controller. The user can connect to the controller through the remote controller to control the working states of the directional lighting module 470 and the floodlighting module 480.

[0082] The above-mentioned controller can be only used to control the working states of the directional lighting module 470 and the floodlighting module 480, or can be used to control the state of the blade assembly 300. As described above, the controller can be integrally provided on the circuit board, thereby further improving the structural compactness of the ceiling fan light.

[0083] In the above embodiments of the present invention, the differences between the embodiments are mainly described. As long as the different optimization features between the embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be elaborated here.

[0084] The above are only the embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
