Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, specifically an LED modular lighting device. Background Technology

[0002] With the rapid development of LED lighting technology, LED lamps, due to their advantages such as high efficiency, energy saving, long lifespan, and environmental friendliness, have been widely used in various fields such as indoor and outdoor lighting, landscape lighting, and commercial displays. In practical applications, different lighting scenarios have diverse requirements for the installation height, illumination angle, and light spot distribution of lighting devices. Currently, existing LED lighting devices mainly suffer from the following shortcomings:

[0003] Poor adaptability to installation height: Traditional LED lighting fixtures are mostly of fixed length or have a single installation method. When the installation height needs to be adjusted, it is often necessary to replace the hanging rod or bracket of different specifications, which is cumbersome and has poor adaptability.

[0004] Inconvenient lighting angle adjustment: The illumination angle of existing lamps is mostly fixed or can only be finely adjusted in one direction, making it difficult to achieve precise adjustment with multiple degrees of freedom and a wide range, which cannot meet the needs of scenarios that require specific lighting angles.

[0005] Low modularity: Individual lighting devices can often only be installed independently, making it difficult to achieve modular combination and series connection between multiple lamps, and it is impossible to flexibly expand the lighting coverage according to site requirements.

[0006] Installation and disassembly are complicated: Light fixtures are mostly fixed with screws, and disassembly and assembly require tools, making maintenance and replacement inconvenient, especially for occasions where the lighting layout needs to be frequently adjusted, resulting in low efficiency.

[0007] Cumbersome wiring: Power supply and signal transmission between multiple light fixtures require complex wiring, which affects aesthetics and increases installation costs.

[0008] Insufficient positioning accuracy: In scenarios where precise positioning of lighting locations is required, the positioning and fixing methods of existing devices are not reliable enough and are prone to displacement.

[0009] Therefore, there is an urgent need for an LED modular lighting device that can achieve adjustable installation height, flexible lighting angle, convenient modular combination, and quick installation and disassembly. Summary of the Invention

[0016] As a preferred embodiment of the present invention, the mounting groove mechanism includes a plurality of concentrically arranged mounting circular grooves on the mounting square plate, and mounting through grooves are provided between the mounting circular grooves.

[0017] As a preferred embodiment of the present invention, the positioning rod mechanism includes a positioning housing with the same cross-section as the mounting slot. The positioning housing is fixedly connected to a positioning rod, and a sliding sleeve is slidably connected to the outer side of the positioning rod.

[0019] As a preferred embodiment of the present invention, the lighting mechanism includes a contact threaded rod that is threadedly connected to the mounting base, and the contact threaded rod is connected to an LED lighting lamp.

[0020] As a preferred embodiment of the present invention, the angle adjustment mechanism includes a third positioner fixed on the positioning housing, the third positioner being rotatably connected to a deflection block, the deflection block being rotatably connected to a telescopic sleeve, the telescopic sleeve being internally threaded to a telescopic threaded rod, the end of the telescopic threaded rod away from the telescopic sleeve being rotatably connected to a fourth positioner, and the fourth positioner being fixedly connected to the mounting base.

[0021] As a preferred embodiment of the present invention, each side of the mounting plate is provided with a plurality of magnetic slots, and magnetic posts are provided in the magnetic slots to achieve positioning of adjacent mounting plates.

[0022] The present invention has the following advantages:

[0023] 1. Flexible and Adjustable Installation Height: The connecting rod mechanism, through the cooperation of extension rods, threaded holes, and extension threaded rods, allows for the series connection of any number of extension rods to achieve flexible adjustment of the installation height according to actual installation needs. The locking mechanism connects to the ceiling or other fixed points through threaded sleeves and fixing plates, and works with expansion bolts to achieve a stable installation and ensure the safety of the device.

[0024] 2. Modular design and strong expandability: The series-connected sleeve mechanism is linked to the connecting rod mechanism via the first and second mounting rings. The adjusting sleeve and adjusting rod are threaded together, allowing for adjustment of the spacing between adjacent devices. This enables the series combination of multiple lighting devices to meet the needs of lighting areas of different lengths. The magnetic slot and magnetic plug cooperation allows for quick positioning and connection of adjacent mounting plates, further enhancing the modular expandability.

[0025] 3. Multi-degree-of-freedom adjustment of lighting angle: The angle adjustment mechanism drives the deflection block to rotate through the threaded engagement of the telescopic sleeve and the telescopic threaded rod, thereby causing the mounting base to deflect around the lighting base, realizing the vertical angle adjustment of the lighting mechanism; in conjunction with the sliding of the sliding sleeve along the positioning rod and the linkage of the displacement rod in the positioning rod mechanism, the horizontal position of the lighting mechanism can also be finely adjusted, making the lighting angle adjustment more flexible and precise.

[0026] 4. Quick and convenient installation and disassembly: The positioning rod mechanism uses an elastic element-driven adjusting slide rod to move the displacement rod and deflection rod, causing the contact plate to extend or retract into the positioning housing. This allows for quick installation and disassembly of the positioning housing within the mounting slot mechanism, requiring no tools and simplifying operation. The lighting mechanism in the deflection mounting mechanism is threaded to the mounting base via a contact threaded rod, enabling quick replacement of LED lights.

[0027] 5. Simple wiring and high integration: The positioning rod mechanism has both positioning and conductive functions. The power supply line can be integrated through the positioning rod and contact plate, reducing external wiring and making the overall device simpler and more beautiful.

[0028] 6. Diverse mounting slot structures and strong adaptability: The mounting slot mechanism has multiple concentric mounting circular slots and mounting through slots. Different radii of mounting circular slots can be selected to install and position lighting components as needed, adapting to the layout requirements of different lighting ranges.

[0029] 7. Reliable positioning and good stability: The elastic element in the positioning rod mechanism provides continuous preload, ensuring that the contact plate is always in close contact with the inner wall of the mounting slot, thus ensuring that the positioning lighting assembly is firmly installed and not easily loosened.
