Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, and in particular to a magnetically attached modular lighting fixture. Background Technology

[0002] In daily study and office settings, desk lamps are commonly used lighting devices, and their structure and functionality directly impact the user experience. Traditional desk lamps typically use a fixed-height lamp post, which cannot be flexibly adjusted according to the environment or the user's posture, resulting in limited lighting angles and poor comfort. Furthermore, the lamp post is often a single structure, only serving to support the lamp head, leading to relatively limited overall functionality and room for improvement in product form and performance.

[0003] To address the inconveniences of fixed structures, some desk lamp designs have incorporated foldable, flexible, or multi-section lamp post structures to achieve height adjustment. However, these structures often rely on mechanical hinges, flexible hoses, or other methods for adjustment, which are prone to loosening or damage after prolonged use, severely impacting stability and lifespan. Furthermore, these structures remain limited to basic lighting functions and lack the ability to be customized for different application scenarios.

[0004] With the increasing integration of desktop space functions, users have higher demands for the multi-functionality of desk lamps. For example, they want to integrate modules such as wireless charging, ambient sensing, and voice control into desk lamps to form a central hub for desktop devices. However, most desk lamp products on the market currently do not have reserved modular interfaces or expansion channels, have closed structures, and fixed functions, which cannot adapt to rapidly changing user needs and also restrict the secondary development and life cycle extension of products.

[0005] In view of this, the inventor has designed a magnetic modular lamp, which leads to this invention. Utility Model Content

[0006] The purpose of this application is to provide a magnetic modular lamp that at least solves the problems of existing table lamp pole structures having limited functionality, poor modular expansion capabilities, and the inability to flexibly adjust height and functional configuration according to user needs.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] This application provides a magnetically attached modular lighting fixture, including:

[0013] In a further embodiment, the magnetic track extends along the longitudinal direction of at least one of the first arm and the second arm, and is provided with a guide structure for the module to slide.

[0014] In a further embodiment, the magnetic module includes one or more of the following: a wireless charging module, an ambient light sensor module, a Bluetooth speaker module, or a function control panel module.

[0015] In a further embodiment, an opening for engaging the magnetic track is provided on the outer surface of the first arm or the second arm.

[0016] In a further embodiment, the magnetic module is electrically connected to the power supply conductor of the magnetic track via a slide rail or conductive spring.

[0017] In a further embodiment, a fixed friction ring is provided inside the second boom, which is used to stabilize the telescopic movement of the first boom and prevent eccentric swaying.

[0018] In a further embodiment, a wear-resistant component is provided between the outer wall of the first boom and the inner wall of the second boom, and the wear-resistant component is made of rubber or nylon.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] The new model integrates a magnetic track and replaceable functional modules into the retractable lamp post structure, which not only enables flexible adjustment of the lamp post height, improving ease of use and adaptability, but also introduces a groundbreaking modular expansion design. This allows users to quickly add or replace functional components such as wireless charging, voice control, and sensor recognition according to their actual needs, significantly improving the lamp's functional integration and adaptability to various usage scenarios, and significantly extending the product's life cycle. This overcomes the technical limitations of traditional lamps, such as simple structure, difficulty in expansion, and short life cycle.

[0032] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0033] like Figure 1As shown, this utility model provides a magnetic modular lamp, aiming to solve the problems of traditional desk lamps such as single function, non-expandability, and non-adjustable lamp post height. Based on the traditional gas spring 3 telescopic lamp post structure, this utility model innovatively integrates a magnetic track 4 with a modular design, giving the desk lamp the dual characteristics of "structural adjustment + functional expansion," thus improving its practicality and product lifecycle.

[0034] like Figure 1 and Figure 2 As shown, specifically, the lamp post includes a first arm 1 and a second arm 2, both of which are hollow tubular structures. The first arm 1 can slide and extend within the second arm 2, thus forming a retractable lamp post body. To achieve this telescopic adjustment function, a gas spring 3 assembly is installed between the inner cavities of the first arm 1 and the second arm 2. The gas spring 3 includes a piston rod 31 and a pressure cylinder 32. The end of the piston rod 31 is fixedly connected to the first arm 1, and the end of the pressure cylinder 32 is fixedly connected to the second arm 2. Preferably, a free-type gas spring 3 is used to achieve semi-automatic telescopic adjustment. With this structure, the user only needs to gently pull out or press the lamp post to adjust the height of the lamp head within a limited stroke, meeting the needs of different working environments and lighting angles. The operation is smooth, and the lamp has a long lifespan.

[0035] like Figures 3 to 5 As shown, to improve the stability and durability of the telescopic structure, a wear-resistant component 8 is provided at the end of the first arm 1 near the second arm 2. This wear-resistant component 8 is located within the inner cavity of the second arm 2 and serves as a guide and friction reducer, effectively preventing direct contact between the first arm 1 and the second arm 2 during sliding, thus extending the overall service life. Preferably, the wear-resistant component 8 is made of rubber or engineering plastic and has through holes to ensure free flow of gas within the telescopic cavity, avoiding air resistance from affecting the telescopic performance. Simultaneously, a fixed friction ring 7 is provided on the inner wall of the second arm 2 near the protrusion to limit the eccentric movement of the first arm 1, further enhancing structural stability.

[0036] like Figure 2 As shown, on the outer surface of the lamp post, preferably the first arm 1 or the second arm 2, a longitudinally arranged magnetic track 4 is provided. The track contains a conductor to power the attached functional module. The magnetic track 4 can be encapsulated in a groove on the lamp post surface using a metal recess insert or a conductive PCB track board. A decorative cover can be provided on the surface of the track, automatically fitting and hiding when the module is not in use, thus ensuring the overall aesthetic appearance of the lamp. Through this track structure, the user can attach the magnetic module 5 to a specific position on the lamp post surface. After attachment, the module forms an electrical connection with the conductor inside the track through contacts or conductive springs, enabling power supply. An opening 6 for engaging the magnetic track 4 is provided on the outer surface of the first arm 1 or the second arm 2, which can also serve as a decorative panel.

[0037] like Figure 1 and Figure 2 As shown, the magnetic module 5 is a standardized expansion unit, and its types can vary, including but not limited to: wireless charging module, voice assistant module, ambient light sensor module, Bluetooth speaker module, display control module, etc. Users can selectively configure, slide, adjust, or replace them according to their needs. Each module can have an independent circuit board inside, which performs corresponding functions after being powered by the magnetic track 4, and can communicate with the main controller wirelessly to form an intelligent desktop lighting and control center.

[0038] To achieve a closed-loop circuit for the overall structure, the first arm 1 is connected to a first connector 9, which connects to the lamp holder. The first arm 1 connects to the lamp holder and has an electrical interface. The second arm 2 is connected to a second connector 10, which connects to the lamp base. The second arm 2 connects to the lamp base and has a main power input interface. Both arms form a complete circuit path with the power supply terminal of the magnetic track 4 through internal wiring, thus ensuring the coordinated operation of the module power supply and the main lamp illumination. The magnetic module 5 automatically aligns and closes the circuit when attracted, and disconnects when disassembled. The operation is tool-free and extremely convenient.

[0039] Through the above structural design, this utility model, while ensuring the height adjustment function of the retractable lamp post, innovatively realizes the functional module expansion capability of the lamp post. Users can flexibly configure module components according to different needs, significantly improving the intelligence, integration, and personalized application level of the desk lamp, effectively extending the product life cycle, and enhancing market adaptability. The overall structural design is reasonable, the functions are rich, and it has broad application prospects.

[0040] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
