Description

Technical Field

[0001] This invention relates to the field of lighting fixtures and fans, and more specifically to a lighting fixture and fan whose light-emitting components can be folded and unfolded. Background Technology

[0002] In real life, a typical ceiling light consists of a base and multiple light-emitting components that can be detached and installed on the bottom of the base. During transportation, the light fixture can be disassembled from the base and packaged separately to reduce the packaging volume of the ceiling light. If installation is required, the light-emitting components and the base must be assembled in advance before the ceiling light can be installed.

[0003] However, the above setup has the following drawbacks. First, the assembly of the light-emitting components requires professional personnel and tools, which ordinary consumers cannot easily assemble, increasing the difficulty of assembling the lamps. Second, during transportation or packaging, the fixing screws for assembling the lamps are easily lost, making it impossible to assemble the lamps smoothly and reducing the user experience.

[0004] The design of a lighting fixture that reduces packaging volume during transportation and eliminates the need for reassembly during user installation, thus reducing assembly difficulty, has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by proposing a lamp and fan light whose light-emitting components can be folded and unfolded. By directly and rotatably mounting multiple light-emitting components to a base, the components can fold and unfold relative to the base, avoiding the need for separate packaging and temporary assembly required by traditional methods, which necessitates specialized personnel and tools. It also overcomes the risk of lost components in traditional separate packaging, allowing users to simply unfold the components upon receiving the lamp for immediate installation and use, thus improving the user experience. Furthermore, the light-emitting components include: a light-emitting unit, a swinging component, and a rotating component. The rotating component is rotatably mounted to the base, and one end of the swinging component is connected to the rotating component. The light-emitting unit is pivotally hinged at one end and fixedly connected to the light-emitting unit at the other. In the horizontal direction, the light-emitting unit drives the rotating part to rotate through the swinging part, thereby realizing the horizontal rotation and unfolding of the light-emitting unit. In the vertical direction, the swinging part can swing relative to the rotating part around the pivot hinge structure, so that the light-emitting unit can tilt up at a certain angle in the vertical direction, so that two adjacent light-emitting units are staggered in the horizontal direction, providing room for the light-emitting unit to unfold, so that two adjacent light-emitting units can fold up and down in the unfolded state.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a rotatable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the present invention provides a lamp with light-emitting components that can be folded and unfolded, comprising: a base 10, and a plurality of light-emitting components 20 respectively rotatably mounted on the base 10, wherein the plurality of light-emitting components 20 can be rotatably folded and unfolded relative to the base 10; Each of the light-emitting components 20 includes: a light-emitting unit 21, a swinging member 22, and a rotating member 23. The rotating member 23 is rotatably mounted on the base 10. One end of the swinging member 22 is pivotally hinged to the rotating member 23, and the other end is fixedly connected to the light-emitting unit 21. In the horizontal direction, the light-emitting unit 21 drives the rotating member 23 to rotate through the swing member 22, thereby realizing the rotation, unfolding and retracting of the light-emitting unit 21 in the horizontal direction; In the vertical direction, the swinging member 22 can swing relative to the rotating member 23 around the pivot hinge structure, so that the light-emitting unit 21 can be tilted up at a certain angle in the vertical direction, providing space for the light-emitting unit 21 to be folded up and down, so that two adjacent light-emitting units 21 can be stacked on top of each other in the folded state, and at the same time, it is convenient for the light-emitting unit 21 to rotate and unfold.

[0021] In this invention, by adopting the above-mentioned solution, the light-emitting component 20 can be directly rotated, folded, and unfolded relative to the base 10, avoiding the traditional method of disassembling and packaging the light-emitting component 20 separately, which requires temporary assembly when needed and necessitates professional personnel and tools. This also overcomes the risk of lost assembly parts that can easily occur with the traditional method of disassembling and packaging the light-emitting component 20 separately. Users can simply unfold the light-emitting component 20 upon receiving the lamp and install it, avoiding secondary assembly and improving the user experience. Furthermore, the light-emitting component 20 can swing and tilt at a certain angle in the vertical direction, preventing interference between the light-emitting components 20 during rotation, unfolding, and folding. This also significantly reduces the size of the lamp, further reducing packaging volume during transportation, thereby reducing packaging and transportation costs and facilitating the promotion of the lamp.

[0022] like Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, in order to install the rotating member 23, each rotating member 23 includes: a rotating shaft portion 231 and a limiting protrusion 232 extending outward from the side of the rotating shaft portion 231; the base 10 is provided with a rotating shaft through hole 11 corresponding to each rotating member 23. After the rotating shaft portion 231 extends into the rotating shaft through hole 11 from the top opening of the rotating shaft through hole 11, the limiting protrusion 232 abuts against the top opening of the rotating shaft through hole 11, so that the rotating member 23 rotates relative to the base 10 along the rotating shaft through hole 11.

[0023] To position the rotation angle of the rotating component 23, the base 10 is provided with a fixing sleeve 12 at the position corresponding to each of the rotating shaft through holes 11, and the fixing sleeve 12 is arranged around the corresponding rotating shaft through hole 11; each of the limiting protrusions 232 is provided with an elastic positioning protrusion 233 on its side, and the inner wall of the fixing sleeve 12 is provided with at least two rotation positioning slots 121 at the position corresponding to the elastic positioning protrusion 233. The elastic positioning protrusion 233 can be engaged with each of the rotation positioning slots 121 respectively to position the unfolded position and the retracted position of the light-emitting unit 21.

[0024] In this invention, the number of the rotating positioning slots 121 is preferably two, and the two rotating positioning slots 121 are respectively provided at the unfolded position and the retracted position of the light-emitting component 20. However, this invention is not limited to the present invention. The number of rotating positioning slots 121 can also be three or more. Increasing the number of rotating positioning slots 121 can be used to precisely control the rotation angle of the rotating component 23, thereby precisely controlling the rotation angle of the light-emitting component 20. This invention does not limit this.

[0025] Specifically, the elastic positioning protrusion 233 includes an elastic part 2331 and a positioning part 2332. The elastic part 2331 is a frame that can elastically recess inward after the limiting protrusion 232 is hollowed out. The positioning part 2332 is a protruding structure extending outward from the outer side of the frame. In practice, when the protruding structure slides out of the rotating positioning groove, it can press the frame inward, causing the frame to recess inward. When the protruding structure re-enters the rotating positioning slot 121, the frame elastically recovers its original shape.

[0026] In order to limit the rotation angle of the rotating member 23, each of the limiting protrusions 232 is provided with a limiting protrusion 234 on its side. The inner wall of the corresponding fixed sleeve 12 is provided with a limiting groove 122 at the position corresponding to the limiting protrusion 234. The limiting protrusion 234 extends into the limiting groove 122 and can slide along the direction of the limiting groove 122 to limit the rotation angle of the rotating member 23.

[0027] To prevent the rotating component 23 from dislodging from the rotating shaft, each light-emitting component 20 further includes: a fixing screw 24 and a limiting washer 25. The fixing screw 24 passes through the limiting washer 25 and extends into the fixing sleeve 12 to fix the limiting washer 25 to the fixing sleeve 12. The limiting washer 25 abuts against the limiting protrusion 232 and limits the abutting protrusion 232 to the top opening of the rotating shaft through hole 11, thereby preventing the rotating component 23 from dislodging from the top opening of the rotating shaft through hole 11.

[0028] Not limited to the invention, in order to prevent the rotating part 23 from coming out of the rotating shaft through the inner part, a mounting cover plate can also be provided on the top of the limiting protrusion 232. After the fixing screw passes through the mounting cover plate, it extends into the fixing sleeve 12 to fix the mounting cover plate to the fixing sleeve 12. Then the mounting cover plate abuts against the top of the limiting protrusion 232, limiting the abutting protrusion 232 to the top opening of the rotating shaft through hole 11, thus preventing the rotating part 23 from coming out of the top opening of the rotating shaft through hole 11.

[0029] To install the oscillating component 22 and to position its oscillation angle, the light-emitting unit 21 is provided with a fixing groove 211. After one end of the oscillating component 22 is inserted into the fixing groove 211, a fixing screw passes through the light-emitting unit 21 at the position of the fixing groove 211 and extends into one end of the oscillating component 22 for fixation. The rotating shaft 231 is provided with an oscillation groove 2311, and the light-emitting unit 21 has a clearance notch 212 on the side facing the fixing groove 211. The other end of the oscillating component 22 extends into the notch. The oscillating groove 2311 is pivotally hinged to the oscillating groove 2311, so that the light-emitting unit 21 swings toward the clearance notch 212; the bottom of the oscillating groove 2311 is provided with an elastic positioning member 2312, the elastic positioning member 2312 is provided with at least two oscillating positioning slots 23121, and the other end of the oscillating member 22 is also provided with a positioning tip 221, the positioning tip 221 can be engaged with each of the oscillating positioning slots 23121 respectively, for positioning the oscillation angle of the light-emitting unit 21.

[0030] In order to lock and unlock the oscillating member 22 relative to the rotating member 23, each light-emitting component 20 further includes: a locking plate 26; the oscillating groove 2311 has a guide groove 2313 on the inner wall corresponding to the oscillation direction of the oscillating member 22, the fixing groove 211 has a locking groove 213 on the inner wall on one side of the guide groove 2313, the guide groove 2313 communicates with the locking groove 213, and the locking plate 26 can slide in the guide groove 2313 and the locking groove 213; When the light-emitting component 20 is located below the lamp, gravity drives the locking plate 26 to slide until one end of it extends into the guide groove 2313 and engages, and the other end of it extends into the locking groove 213 and engages, so that the swinging component 22 is locked relative to the swinging groove 213. When the light-emitting component 20 is located above the lamp, gravity drives the locking plate 26 to slide along the direction of the guide groove 2313 until the other end of the locking plate 26 disengages from the locking groove 213, thereby releasing the swing member 22 from the swing groove 213.

[0031] When the light-emitting component 20 needs to be folded, the lamp is first inverted so that the light-emitting component 20 is above the lamp. Gravity drives the locking plate 26 to slide along the direction of the guide groove 2313 until the other end of the locking plate 26 disengages from the locking groove 213, until the locking plate 26 is completely slid into the guide groove 2313. The swing member 22 is unlocked relative to the rotating member 23. The light-emitting unit 21 is driven to swing the swing member 22 relative to the rotating member 23 around the pivot hinge structure, so that the light-emitting unit 21 is tilted up at a certain angle in the vertical direction. Then, the light-emitting unit 21 is driven to rotate the rotating member 23 through the swing member 22, so that the light-emitting component 20 can be folded. Moreover, since the light-emitting unit 21 is tilted up at a certain angle in the vertical direction, two adjacent light-emitting units 21 will not interfere with each other when folded and will overlap.

[0032] When the light-emitting component 20 is unfolded, the light-emitting unit 21 is driven in the opposite direction to rotate the rotating component 23 via the swinging component 22, thereby unfolding the light-emitting component 20. Then, the light-emitting unit 21 is driven in the opposite direction to swing the swinging component 22 relative to the rotating component 23 around the pivot hinge structure, thereby restoring the light-emitting unit 21 to a horizontal state in the vertical direction. Finally, the lamp is placed upright as during installation, so that the light-emitting component 20 is located below the lamp. Gravity drives the locking plate 26 to slide from being entirely within the guide groove 2313 until one end of the locking plate 26 extends into the guide groove 2313 and engages, and the other end extends into the locking groove 213 and engages, thereby locking the swinging component 22 relative to the swing groove 2311, preventing the swinging component 22 from swinging relative to the swing groove 2311.

[0033] To realize the function of the light-emitting component 20, each light-emitting component 20 further includes: a light source 27 and a light-transmitting lamp cover 28; a light source mounting groove 214 is provided along the length direction of the light-emitting unit 21, the light source 27 is installed in the light source mounting groove 214, and the light-transmitting lamp cover 28 is installed on the light-emitting unit 21 and then covered by the light source mounting groove 214, and the light emitted by the light source 27 passes through the light-transmitting lamp cover 28 and is emitted to the outside.

[0034] In order to supply power to the light source 27, the bottom of the swing groove 2311 is provided with a wire passage notch 2314, and one side of the swing member 22 is provided with a wire passage channel 222 communicating with the wire passage notch 2314. The bottom of the fixed groove 211 is provided with a wire passage groove 215 communicating with the wire passage channel 222 and the light source mounting groove 214 respectively. The power line passes through the wire passage notch 2314, the wire passage channel 222 and the wire passage groove 215 in sequence and then extends into the light source mounting groove 214 to be electrically connected to the light source 27, thereby supplying power to the light source 27 through the power line.

[0035] The present invention also provides a fan light, which includes a light-emitting component 20 as described above that is capable of being folded and unfolded.

[0036] Obviously, the above embodiments of the present invention are merely examples to clearly illustrate the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications arising from the essential spirit of the present invention still fall within the scope of protection of the present invention.
