Description

Technical Field

[0001] This application relates to the field of lighting equipment technology, and in particular to a lamp holder and lighting assembly. Background Technology

[0002] In home, office, and commercial lighting scenarios, some lighting fixtures (such as chandeliers, floor lamps, and table lamps) require height adjustment to adapt to different lighting needs and usage scenarios. In related technologies, a suspension device is typically used to achieve this height adjustment. The internal rotating component of the suspension device has a wire wound around it; by controlling the rotation of this component, the length of the wire extending outside the suspension device can be adjusted, thus achieving height adjustment. This suspension device, while suspending the lighting fixture, also needs to meet the electrical connection requirements between the fixture and the power supply. Currently, a conductive slip ring is usually installed inside the suspension device. This slip ring maintains the electrical connection between the rotating component and the power supply while allowing the component to rotate. However, when the conductive slip ring wears down, it can lead to poor contact or even power outages between the rotating component and the power supply, significantly impacting the reliability and lifespan of the suspension device.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0017] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.

[0018] The technical solutions disclosed in the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0019] Please refer to Figures 1 to 7 This application discloses a lamp hovering device. The core of the lamp hovering device is to realize the height adjustment of the lighting fixture while ensuring stable power supply to the circuit during the adjustment process.

[0020] The aforementioned lamp holder may include three core components: a housing 100, a cover plate 200, and a winding assembly 300. The housing 100 serves as the mounting and protective carrier for the entire lamp holder. The housing 100 is a cylindrical structure (such as a cylinder or prism) with one open end and a hollow interior. The inner cavity of the housing 100 accommodates the winding assembly 300, part of the wire 600 structure, and electrical connection structures. The housing 100 can be made of materials such as plastic or metal that possess certain pressure resistance and wear resistance. The housing 100 protects the internal components from external damage and dust intrusion.

[0021] like Figure 1 and Figure 2 As shown, the winding assembly 300 is assembled in the inner cavity of the housing 100 and is rotatably connected to the housing 100. The winding assembly 300 is used to wind the wire 600, and the end of the wire 600 extending out of the housing 100 can be used to connect to the lighting fixture. When the user pulls the lighting fixture, the part of the wire 600 extending out of the housing 100 will extend. At this time, the winding assembly 300 will rotate relative to the housing 100, gradually releasing the wire 600 wound on it. When the user releases the lighting fixture or pushes the lighting fixture upward, the winding assembly 300 can rotate in the opposite direction under the action of the torsion spring 320, rewinding and retracting the extended wire 600, thereby realizing the height adjustment of the lighting fixture. The end of the wire 600 extending out of the housing 100 can be provided with a connector, which can be used for electrical connection with the lighting fixture.

[0022] The cover plate 200 adopts a shape (such as circular or square) that matches the opening end of the housing 100. The cover plate 200 can be installed on the opening end of the housing 100 by means of snap-fit ​​connection, threaded connection, or heat fusion connection to achieve a seal on the inner cavity of the housing 100 and prevent dust and debris from entering. A first electrical connection part 400 is fixedly provided on the side of the cover plate 200 facing the inner cavity of the housing 100. The first electrical connection part 400 is connected to an external power source (such as a mains adapter or battery pack) through a wire harness or conductive structure to introduce power supply current. Correspondingly, a second electrical connection part 500 is fixedly provided on the side of the winding assembly 300 near the cover plate 200. The second electrical connection part 500 can be electrically connected to the wire 600 wound on the winding assembly 300, specifically to the end of the wire 600 located in the inner cavity of the housing 100.

[0023] The first electrical connection part 400 and the second electrical connection part 500 are connected by mutual plugging, and after plugging, the two can rotate relative to each other. That is, when the winding assembly 300 rotates relative to the housing 100, the second electrical connection part 500 will rotate with the winding assembly 300, while the first electrical connection part 400 remains fixed with the cover plate 200. The first electrical connection part 400 and the second electrical connection part 500 always maintain an electrical connection during relative rotation, thereby ensuring that the power supply to the lighting fixture will not be interrupted when the wire 600 is extended or retracted, avoiding problems such as poor contact or even power outage.

[0024] As described above, the lamp holder disclosed in this application improves upon related technologies. The lamp holder includes a housing 100, a cover plate 200, and a winding assembly 300. The winding assembly 300 is disposed within the cavity of the housing 100 and rotatably connected to the housing 100 to allow for the extension and retraction of the conductor 600. A first electrical connection portion 400 on the cover plate 200 is inserted into and rotatably connected to a second electrical connection portion 500 on the winding assembly 300, ensuring continuous circuit conduction when the winding assembly 300 rotates. This application, through its rotatable electrical connection structure, ensures stable power supply during the extension and retraction of the conductor 600, improving the reliability and lifespan of the lamp holder. Simultaneously, the structural design of the winding assembly 300 enhances the stability of the lamp holder, making it suitable for various lighting scenarios requiring height adjustment.

[0025] In one optional embodiment of this application, to achieve the function of "plugging in and being able to rotate relative to each other" between the first electrical connection part 400 and the second electrical connection part 500, the first electrical connection part 400 and the second electrical connection part 500 can adopt a "male + female" plug-in structure. Specifically, one of the first electrical connection part 400 and the second electrical connection part 500 may include an electrical connection male port 510, and the other of the first electrical connection part 400 and the second electrical connection part 500 may include an electrical connection female port 410. After the electrical connection male port 510 and the electrical connection female port 410 are plugged in, a stable mechanical fit and electrical connection are formed. In this embodiment, the first electrical connection part 400 includes an electrical connection female port 410, and the second electrical connection part 500 includes an electrical connection male port 510 (it can also be reversed according to the installation space and wiring requirements, with the first electrical connection part 400 including an electrical connection male port 510 and the second electrical connection part 500 including an electrical connection female port 410, both of which are within the protection scope of this application). By using a male-female plug-in connection, not only can the connection between the two be guaranteed to be firm and prevent them from falling off due to vibration or pulling during use, but the assembly process can also be simplified and assembly efficiency improved.

[0026] Furthermore, such as Figures 3 to 7 As shown, the male electrical connector 510 may include a first metal spring 511 and a second metal spring 512. The first metal spring 511 and the second metal spring 512 may be made of a conductive elastic metal material (such as copper, silver, etc.) and have a certain elastic deformation capability. The first metal spring 511 can be used to connect to the positive terminal of the wire 600, and the second metal spring 512 can be used to connect to the negative terminal of the wire 600.

[0027] The electrical connection female port 410 may include a first conductive ring 411 and a second conductive ring 412. The first conductive ring 411 and the second conductive ring 412 may be made of a metal with excellent conductivity (such as copper, silver, etc.), and their central axes may coincide. The first conductive ring 411 can be used to connect to the positive terminal of the power supply, and the second conductive ring 412 can be used to connect to the negative terminal of the power supply. The inner diameter of the first conductive ring 411 is larger than the outer diameter of the second conductive ring 412. The first conductive ring 411 is fitted over the second conductive ring 412, and an annular insertion hole 413 is formed between the first conductive ring 411 and the second conductive ring 412.

[0028] When the first metal spring 511 and the second metal spring 512 are respectively inserted into the annular insertion hole 413, the first metal spring 511 can be slidably connected and electrically connected to the inner annular surface of the first conductive ring 411, and the second metal spring 512 can be slidably connected and electrically connected to the outer annular surface of the second conductive ring 412, thereby forming a complete power supply circuit. Since the first metal spring 511 and the second metal spring 512 have a certain elasticity, they can always maintain contact pressure with the first conductive ring 411 and the second conductive ring 412. Even if the first metal spring 511 rotates relative to the first conductive ring 411 and the second metal spring 512 rotates relative to the second conductive ring 412, the electrical connection can be maintained by sliding the contact surfaces, avoiding the interruption of the electrical connection due to rotation.

[0029] To achieve a stable connection between the first electrical connection 400 and the cover plate 200, and between the second electrical connection 500 and the winding assembly 300, in this embodiment, as follows: Figures 3 to 7 As shown, the first electrical connection portion 400 may further include a first base 420, which may be made of an insulating material (such as plastic). One end of the first base 420 may be fixedly connected to the inner side of the cover plate 200 by means of screw fixing or injection molding. The first base 420 has a ring structure and includes a first ring body 421 and a second ring body 422. The first ring body 421 is sleeved outside the second ring body 422. The first conductive ring 411 may be installed inside the first ring body 421 by means of inlaying, bonding or screw fixing. Similarly, the second conductive ring 412 may be installed outside the second ring body 422 by means of inlaying, bonding or screw fixing.

[0030] Furthermore, the second electrical connection portion 500 may also include a second base 520, which may also be made of an insulating material. One end of the second base 520 may be fixedly connected to the winding assembly 300 by means of screw fixing or injection molding. The second base 520 has a ring structure, with the first metal spring 511 located on the outer side of the second base 520 and the second metal spring 512 located on the inner side of the second base 520.

[0031] With at least a portion of the second base 520 inserted into the insertion space enclosed by the first ring 421 and the second ring 422, the male electrical connector 510 and the female electrical connector 410 are interlocked, thereby enabling the power supply circuit to be connected. By setting the first base 420 and the second base 520, not only can the male electrical connector 510 and the female electrical connector 410 be stably fixed, but the conductive components can also be separated from other components, preventing short circuits and improving safety in use.

[0032] To facilitate the connection of the first electrical connection portion 400 to the power source, in this embodiment, the first electrical connection portion 400 may further include a first connector 430 and a second connector 440, which are respectively mounted on the cover plate 200. The first connector 430 and the second connector 440 may be made of metal materials (such as copper, silver, etc.). One end of the first connector 430 is electrically connected to the first conductive ring 411, and the other end of the first connector 430 protrudes from the cover plate 200. The portion of the first connector 430 protruding from the cover plate 200 can be connected to the positive terminal of the power source. One end of the second connector 440 is electrically connected to the second conductive ring 412, and the other end of the second connector 440 protrudes from the cover plate 200. The portion of the second connector 440 protruding from the cover plate 200 can be connected to the negative terminal of the power source. By providing the first connector 430 and the second connector 440, the convenience of connecting the first electrical connection portion 400 to the power source can be improved, thereby increasing assembly efficiency.

[0033] In one optional embodiment of this application, to improve the safety of the lighting components, such as... Figures 3 to 7 As shown, the first electrical connection portion 400 may further include a first grounding member 450, which passes through the cover plate 200. One end of the first grounding member 450 extends into the inner space of the second ring body 422, and the other end can be used to connect to the ground wire of the power supply. Correspondingly, the second electrical connection portion 500 may further include a second grounding member 530, which is disposed in the inner space of the second base body 520 and can be used to connect to the grounding connection of the conductor 600. The first grounding member 450 and the second grounding member 530 may be made of metal material, and may be a sheet structure, a column structure, etc.

[0034] When at least a portion of the second base 520 is inserted into the insertion space enclosed by the first ring 421 and the second ring 422, the second grounding member 530 can extend into the inner space of the second ring 422 and be electrically connected to the first grounding member 450, thereby enabling the conduction of the grounding circuit between the power supply, the first electrical connection part 400, the second electrical connection part 500, and the lighting fixture.

[0035] In addition to winding the conductor 600 and rotating the second electrical connection 500, the winding assembly 300 also needs to have a hovering damping function to ensure that the lighting fixture can remain stable at any height without rebounding or falling. In this embodiment, the winding assembly 300 may include a winding body 310, a torsion spring 320, and a friction pad 330. The winding body 310, as the core skeleton of the winding assembly 300, may have a cylindrical structure. One or more winding grooves 311 are formed on the outer circumference of the winding body 310, and the conductor 600 can be wound in the winding grooves 311. The second electrical connection 500 (including a second base 520, a first metal spring 511, and a second metal spring 512) may be fixedly installed on the side of the winding body 310 near the cover plate 200, and the second electrical connection 500 may rotate together with the winding body 310.

[0036] The torsion spring 320, serving as the power source for the winding of the wire 600, can be made of stainless steel and possesses good elasticity and fatigue resistance. The torsion spring 320 is installed on the side of the winding body 310 away from the cover plate 200. One end (fixed end) of the torsion spring 320 is fixedly connected to the housing 100 by a snap-fit ​​or welding, while the other end (movable end) is fixedly connected to the winding body 310. Figure 1 and Figure 2 As shown, when the user pulls the lighting fixture, the winding body 310 rotates to release the wire 600, and the torsion spring 320 is twisted to store force; when the user releases the lighting fixture, the stored force of the torsion spring 320 is released, which can drive the winding body 310 to rotate in the opposite direction and retract the wire 600.

[0037] The friction pad 330 can be made of a wear-resistant material with a high coefficient of friction (such as rubber, nylon, or graphite pads). The friction pad 330 is installed between the inner wall of the housing 100 and the winding body 310 (such as between the bottom wall of the housing 100 and the winding body 310, and / or between the side wall of the housing 100 and the winding body 310). The core function of the friction pad 330 is to provide damping force. When the winding body 310 rotates, the friction pad 330 will generate friction between the housing 100 and the winding body 310. After the lighting fixture is adjusted to any height, this friction force is balanced with the elastic force of the torsion spring 320 and the weight of the lighting fixture, thereby achieving stable suspension of the lighting fixture and preventing the lighting fixture from rebounding due to excessive elastic force of the torsion spring 320 or falling due to insufficient elastic force of the torsion spring 320.

[0038] To achieve stable rotation between the winding body 310 and the housing 100, in this embodiment, a rotating shaft 312 can be integrally formed or fixedly connected to the center position of the side of the winding body 310 away from the cover plate 200. This rotating shaft 312 is cylindrical and can be made of the same material as the winding body 310 (e.g., plastic), or a metal material (e.g., stainless steel) to improve wear resistance. Correspondingly, as... Figure 1 As shown, a shaft hole 110 matching the rotating shaft 312 is provided at the center of the bottom of the housing 100. The end of the rotating shaft 312 extends into the shaft hole 110. The rotating shaft 312 and the shaft hole 110 can be fitted with a clearance or a bearing can be added to reduce the rotational friction between them and ensure that the winding body 310 rotates smoothly without jamming. At the same time, a limiting protrusion (such as an annular step) can be provided at the end of the rotating shaft 312 to prevent the winding body 310 from moving axially during rotation and improve the stability of rotation.

[0039] In one optional embodiment of this application, a wire hole 120 is provided on the side of the housing 100, through which the wire 600 can extend out of the housing 100, and the end of the wire 600 extending out of the housing 100 can be connected to a lighting fixture. The diameter of the wire hole 120 can be slightly larger than the diameter of the wire 600 (leaving a small gap to facilitate the movement of the wire 600), and the edge of the wire hole 120 can be chamfered (e.g., rounded) to remove sharp edges and avoid scratching the wire 600.

[0040] Please refer to Figures 1 to 7 This application also discloses a lighting component, which may include a power supply, a wire 600, a lighting fixture, and the lighting fixture hoverer described above.

[0041] The power supply serves as the power source for the entire lighting assembly and can be a mains adapter, a rechargeable battery pack, or a solar panel. The power supply's output is electrically connected to the first electrical connection part 400 of the luminaire's suspension via a wire 600, providing a stable current to the lighting assembly. The wire 600 can be made of a flexible and abrasion-resistant material. One end of the wire 600 is wound within the winding groove 311 of the winding assembly 300, and this end is electrically connected to the second electrical connection part 500 on the winding assembly 300. The other end of the wire 600 passes through the wire hole 120 of the housing 100, extends outside the housing 100, and connects to the lighting fixture. The lighting fixture can be any type of light source, such as LED lights, incandescent lamps, or fluorescent lamps. The structure of the lighting fixture can be designed as a pendant lamp, table lamp, floor lamp, etc.

[0042] As described above, the lamp holder and lighting assembly disclosed in this application improve upon related technologies. The lamp holder includes a housing 100, a cover plate 200, and a winding assembly 300. The winding assembly 300 is disposed within the cavity of the housing 100 and rotatably connected to the housing 100 to allow for the extension and retraction of the conductor 600. A first electrical connection portion 400 on the cover plate 200 is inserted into and rotatably connected to a second electrical connection portion 500 on the winding assembly 300, ensuring continuous circuit conduction when the winding assembly 300 rotates. This application, through its rotatable electrical connection structure, ensures stable power supply during the extension and retraction of the conductor 600, improving the reliability and lifespan of the lamp holder. Simultaneously, the structural design of the winding assembly 300 enhances the stability of the lamp holder, making it suitable for various lighting scenarios requiring height adjustment.

[0043] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different technical features between the various embodiments are not contradictory, they can be combined to form more specific embodiments. For the sake of brevity, they will not be described in detail here.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
