Description

Technical Field

[0001] This utility model relates to a double-headed wall lamp, specifically a magnetic double-headed wall lamp. Background Technology

[0002] Existing wall lamp installation structures typically employ mechanical fixing or magnetic adsorption for installation and adjustment. Magnetic installation, due to its advantages of convenient assembly and disassembly and simple structure, is widely used in practical applications. However, traditional magnetic wall lamps have some technical problems in actual use. For example, the magnetic structure is usually planar adsorption. When the user rotates and adjusts the lamp, due to the lack of effective limiting and cooperating structures, the lamp body is prone to shifting or detaching from its original adsorption surface during rotation, leading to reduced stability and safety of the lamp, especially when the lamp head is large or the angle is frequently adjusted. Furthermore, the connection between the traditional sensor head and the control board often uses a direct metal wire connection. This wire is usually rigidly connected inside the housing. During assembly or use, if the sensor head is subjected to external force or movement, the wire is easily bent, deformed, or even broken, affecting the normal operation of the entire lamp.

[0003] To address the aforementioned technical problems, this utility model proposes a magnetic double-headed wall lamp with optimized structural design. Firstly, an annular rotating cavity is provided inside the magnetic base, with a magnetic plate at the bottom of this cavity. Simultaneously, a stepped rotating cavity is formed by an inward recess on the bottom surface, allowing the external circular metal plate to embed into this stepped structure when attracted to the magnetic base. This provides magnetic attraction while simultaneously creating axial and radial limiting relationships, preventing the wall lamp from easily detaching from the attraction surface during rotational adjustment. It also enables circumferential rotation around the metal plate, further enhancing the stability and safety of the lamp body during rotation. On the other hand, the sensor head and the control board no longer use the traditional hard wire connection method, but instead use a flexible flat cable for connection. The sensor head is connected to the control board's connector for electrical connection. The sensor plate located at the bottom of the sensor head can be reliably fixed to the housing with screws. While maintaining a stable electrical connection, this greatly improves the sensor head's resistance to pressure and damage during transportation, installation and daily use. It effectively avoids the problem of wire breakage or loosening due to external pressure or impact, and improves the reliability and durability of the entire lamp's electrical connection. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a magnetic double-headed wall lamp. Through an innovative design of a stepped rotating cavity structure and a flexible cable connection method, it significantly improves the stability of the magnetic wall lamp during rotation and the reliability of the sensor head connection, possessing good practical value and promising prospects for promotion.

[0005] This utility model is achieved through the following technical solution: a magnetic double-headed wall lamp, comprising:

[0006] The housing contains a control motherboard, and lighting lamp heads are provided at both ends of the housing.

[0007] A magnetic base is provided on the housing. The magnetic base has an annular rotating cavity. A magnetic plate is provided on the bottom surface of the annular rotating cavity. The magnetic base is magnetically attracted to an external circular metal plate.

[0008] The sensor head is mounted on the housing on the side opposite to the magnetic base, and the sensor head is electrically connected to the control motherboard via a flexible flat cable.

[0009] As a preferred technical solution, a stepped rotating cavity is formed between the bottom surface of the magnetic absorbing sheet and the magnetic attraction action. During magnetic attraction, the outer circular metal sheet is snapped into the stepped rotating cavity and magnetically attracted to the magnetic absorbing sheet.

[0010] As a preferred technical solution, a sensing plate is provided at the bottom of the sensing head, and the sensing plate is electrically connected to the control motherboard via a flexible flat cable.

[0011] As a preferred technical solution, one end of the flexible flat cable is provided with a connector, and the control motherboard is provided with a socket, and the flexible flat cable is electrically connected to the socket through the connector.

[0012] As a preferred technical solution, the sensing plate is fixedly connected to the housing by screws.

[0013] As a preferred technical solution, the housing is provided with heat dissipation fins, and the sensing head is disposed on the heat dissipation fins.

[0014] As a preferred technical solution, the housing is further provided with a charging interface and control buttons at the position corresponding to the control motherboard.

[0015] As a preferred technical solution, the shell and the magnetic base are in a "T" shape.

[0016] The beneficial effects of this utility model are as follows: By setting a recessed stepped rotating cavity inside the magnetic base, the external circular metal sheet can be embedded in the stepped structure when magnetically attracted, thereby achieving magnetic positioning while forming a mechanical limiting fit, effectively preventing the lamp body from falling off or shifting during rotation adjustment, and improving the stability and safety of the lamp after installation; at the same time, the lamp body can rotate smoothly in the circumferential direction along the circular metal sheet, making the user experience more flexible and smooth, adapting to different angle lighting needs, and enhancing practicality.

[0017] Furthermore, this utility model uses a flexible flat cable to replace the traditional metal wire to achieve electrical connection between the sensor head and the control motherboard. The combination of the flexible flat cable and the connector not only simplifies the assembly process, but also provides greater flexibility and bending resistance in structure, avoiding problems such as wire breakage and poor electrical connection caused by pressure or movement of the sensor head, thus fundamentally improving the reliability and service life of the entire lamp electrical system.

[0018] Furthermore, the sensor head structure is fixed to the housing with screws via the sensor plate, and the arrangement of heat dissipation fins helps improve the thermal stability of the sensing area and prevents performance drift of the sensing device after long-term use. Meanwhile, the housing structure is arranged in a "T" shape, facilitating symmetrical arrangement and center of gravity balance of the lighting heads. Control buttons and charging interfaces are integrated into the corresponding control board area within the housing, resulting in a rational layout, convenient operation, and a simple, compact, and highly integrated overall lamp design, making it highly valuable for market applications.

[0025] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0026] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0027] like Figures 1-3 As shown, the specific implementation of this utility model of a magnetic double-headed wall lamp is as follows:

[0028] This magnetic double-head wall lamp mainly includes a housing 1, a magnetic base 6, a sensor head 2, a control board 7, a lamp holder 3, a flexible cable 9, and a sensor plate 8. The housing 1 is an integral, elongated structure used to support and house the electrical components. Its material can be aluminum alloy or ABS flame-retardant plastic to ensure good heat dissipation and structural strength. Inside the housing 1 is a control board 7, used to implement the electrical control functions of the entire lamp, including power management, sensor signal processing, lighting control, and charging. The control board 7 is installed in the middle of the housing 1 and secured with screws to ensure it will not shift or loosen during transportation and use.

[0029] Lighting heads 3 are located at both ends of the housing 1. Each lighting head contains multiple LED beads and is connected to the housing 1 body via a metal bracket or thermally conductive adhesive to enhance heat dissipation. The lighting heads 3 are connected to the control mainboard 7 via conductive cables, enabling synchronous or independent control of both lights. Users can adjust the light brightness or set a timer to turn off the lights as needed. The lighting heads 3 are equipped with a light-transmitting cover, which is integrally injection molded from milky white PC material, providing both a soft light effect and mechanical protection.

[0030] The magnetic base 6 is located in the middle of the back of the housing 1, used to magnetically mount the entire lamp to a wall or other metal surface. The magnetic base 6 has a circular structure with an annular rotating cavity 5 inside. A magnetic plate 4 is installed on the bottom surface of the rotating cavity. The magnetic plate 4 can be made of neodymium iron boron high-performance permanent magnet material to ensure sufficient magnetic adhesion. An annular recessed stepped rotating cavity is formed between the bottom surface of the magnetic plate 4 and the magnetic action. The stepped rotating cavity has a stepped concave structure, and its outer diameter is slightly larger than the diameter of the outer circular metal plate. This allows the pre-placed outer circular metal plate to easily snap into the stepped rotating cavity and magnetically engage with the magnetic plate 4 during installation. Through this structural cooperation, not only is a firm adsorption and fixation achieved, but also smooth rotation in the circumferential direction is achieved while maintaining the magnetic adsorption state. Users can easily adjust the wall lamp's illumination angle without worrying about the lamp body slipping or shifting, effectively improving the safety and stability of the lamp body during rotation.

[0031] The sensor head 2 is located on the front or side of the housing 1, specifically on the side opposite to the magnetic base 6. The sensor head 2 contains an infrared or microwave sensing module for automatic control of the light turning on when someone is present and turning off when they leave. The sensor head 2 is electrically connected to the control board 7 inside the housing 1 via a flexible flat cable 9. The flexible flat cable 9 can be a multi-core FPC flexible circuit board or TPE-coated wire, possessing good flexibility and tensile strength. One end of the flexible flat cable 9 is equipped with a standard connector. Correspondingly, the control board 7 is equipped with a connector socket. The connector and connector socket have a snap-fit ​​or self-locking structure, facilitating disassembly and reassembly during later assembly and maintenance, and also improving the overall electrical connection reliability.

[0032] To enhance the structural stability of the sensor head 2, a sensor plate 8 is installed at its bottom. The sensor plate 8 is a small support base plate, injection molded from ABS or PC material, possessing a certain strength and dimensional accuracy. The sensor plate 8 is fixedly connected to the housing 1 by screws. During fixing, the flexible flat cable 9 is pressed into the preset limiting groove to prevent the line from shaking or being interfered with by external forces, further improving the overall lamp's shock resistance and service life.

[0033] To improve the heat dissipation performance of the entire lamp, a set of heat dissipation fins are provided on the outside of the housing 1 in the area where the sensor head 2 is located. The fins are integrally formed with the housing 1 or made by die casting and post-processing. They are evenly distributed in the vertical or horizontal direction to increase the contact area with air. Without affecting the aesthetics, the heat dissipation efficiency is effectively improved, ensuring that the LED beads and the control motherboard 7 maintain good thermal stability during long-term operation.

[0034] On the outer surface of the housing 1 near the control motherboard 7, there is also a charging port and control buttons. The charging port is a Type-C or Micro-USB interface, which is connected to an external power source for battery charging. A silicone sealing ring is provided around the interface for dust and water protection. The control buttons are touch-sensitive or touch-sensitive buttons, which can be used to switch lighting modes, manually turn the lights on and off, or switch functions in conjunction with the sensing mode, making it convenient for users to operate.

[0035] In terms of overall structure, the housing 1 and the magnetic base 6 are arranged in a "T" shape. The housing 1 serves as the vertical main structure, while the magnetic base 6 extends horizontally and is installed in the middle, which makes the center of gravity of the lamp stable and the rotation center clear. At the same time, it is also conducive to evenly distributing the magnetic adsorption points on the rotation circumference path, thereby improving the stability of magnetic adsorption.

[0036] This embodiment effectively improves the ease of installation, flexibility of adjustment, and durability of the entire lamp by optimizing the structure of the magnetic base 6, improving the electrical connection method, and refining the installation and heat dissipation arrangement, and has good practical and promotional value.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
