[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] Reference Figures 1-7As shown, this utility model provides a technical solution: an LED lamp with multi-angle adjustable dimming function, including a base 1, a first support rod 2, a second support rod 3, a lifting rod 4, a U-shaped frame 5, and a lamp body 6. The surface of the base 1 is fixedly connected to the first support rod 2. One end of the first support rod 2 is provided with a sliding groove, and the inner wall of the sliding groove of the first support rod 2 is slidably connected to the lifting rod 4. One end of the lifting rod 4 is fixedly connected to the second support rod 3, and one end of the second support rod 3 is fixedly connected to the U-shaped frame 5. The surface of the U-shaped frame 5 is provided with an adjustment device 7, which includes two round blocks 701. Both round blocks 701 are fixedly connected to the surface of the U-shaped frame 5. The ends of the two round blocks 701 that are close to each other are provided with round grooves 702, and the inner walls of the two round grooves 702 are slidably connected to the lifting rod 4. The system has two circular shafts 703 connected to each other. A rotating shaft 704 is fixedly connected to one end of each circular shaft 703 that is close to the other. Two grooves 705 are formed on the arc surfaces of two circular blocks 701. Several limiting grooves 706 are formed at both ends of the rotating shaft 704. A hollow tube 707 is fixedly connected to the inner wall of each groove 705. A sliding rod 708 is slidably connected to the inner wall of the hollow tube 707. A limiting block 709 is fixedly connected to one end of the sliding rod 708. The limiting block 709 is slidably connected to the inner wall of the limiting groove 706. A spring 710 is fixedly connected to the inner wall of each groove 705. One end of the spring 710 is fixedly connected to the limiting block 709. The spring 710 is fitted onto the arc surfaces of the hollow tube 707 and the sliding rod 708. A fixing plate 714 is fixedly connected to the arc surface of the rotating shaft 704. The lamp body 6 is fixedly connected to the surface of the fixed plate 714. Through the adjustment device 7, the circular shaft 703, the rotating shaft 704, and the limiting structure are coordinated, enabling multi-angle rotation of the lamp body 6. This allows for precise coverage of lighting needs in different directions. Whether used as a reading light to focus on a specific area or as an ambient light to diffuse light, users can quickly adjust the illumination angle according to the actual scene, avoiding the blind spots caused by the fixed direction of traditional lamps. The arc surface of the first support rod 2 is equipped with a lifting device 8, which includes a first square plate 81 and a second square plate 82. Both the first square plate 81 and the second square plate 82 are fixedly connected to the arc surface of the first support rod 2. A drive rod 83 is threaded into the internal part of the first square plate 81. One end of the drive rod 83 is rotatably connected to the second square plate 82. The threaded surface of the drive rod 83 is threadedly connected to the connecting plate 84. The arc surface of the first support rod 2 is provided with an elongated hole 85. The inner wall of the elongated hole 85 is slidably connected to the connecting plate 84. One side of the connecting plate 84 is fixedly connected to the lifting rod 4. By setting the lifting device 8, the threaded transmission structure between the drive rod 83 and the connecting plate 84 is achieved, allowing users to precisely adjust the height of the lamp body 6 according to the actual usage scenario. In a living room with a high ceiling, the lamp can be raised to achieve large-area uniform lighting. In a compact study or workbench, lowering the lamp height can concentrate the light more in a local area, meeting the differentiated lighting needs of different spaces and avoiding the problem of light waste or insufficient lighting caused by a fixed lamp height.

[0026] Reference Figure 3 , Figure 4 and Figure 5 As shown in this embodiment: a lever 711 is fixedly connected to the surface of the limiting block 709, allowing the user to quickly disengage the limiting block 709 from the limiting groove 706 simply by gently moving the lever 711, without having to forcefully pull or search for the limiting block 709. This unlocks the rotating shaft 704 and allows for free adjustment of the lamp body's angle 6, significantly reducing the difficulty of operation. Several anti-slip strips 712 are fixedly connected to both sides of the lever 711, and these anti-slip strips 712 are evenly distributed in a linear array on both sides of the lever 711, increasing the surface area of ​​the lever 711. The friction effectively prevents the user's hand from slipping when adjusting the lamp angle, ensuring that the user can firmly grip the dial 711. Several ball bearings 713 are rotatably connected to the inner wall of the circular groove 702. The arc surface of the ball bearings 713 is slidably connected to the circular shaft 703, which transforms the surface contact between the circular shaft 703 and the circular groove 702 into point contact. This greatly reduces the frictional resistance when the two rotate relative to each other, allowing the user to easily rotate the circular shaft 703 and drive the rotating shaft 704 to rotate with less force when adjusting the lamp angle, making the operation more effortless and smooth.

[0027] Reference Figure 6 As shown in this embodiment: two curtains 86 are fixedly connected to the inner wall of the elongated hole 85. The sides of the two curtains 86 that are close to each other are fixedly connected to the connecting plate 84. The curtains 86 are foldable, so that the curtains 86 can fit tightly against the connecting plate 84 and the elongated hole 85 to form a physical barrier, effectively preventing dust, hair, debris and other foreign objects from entering the slide groove through the elongated hole 85, preventing jamming caused by foreign objects entering the slide groove and affecting the normal operation of the lifting device 8. A wear-resistant pad 87 is fixedly connected to the bottom surface of the base 1. The wear-resistant pad 87 is made of rubber, so the rubber wear-resistant pad 87 has excellent friction and can fit tightly against various placement surfaces, whether it is smooth tiles, wooden floors or glass tabletops, effectively preventing the lamp from sliding and shifting due to accidental touch, external vibration or tilt, ensuring that the lamp remains stable during use.

[0028] Working principle: When the user needs to adjust the angle of the lamp body, first pull the lever 711, which is fixedly connected to the limit block 709. The anti-slip strips 712 on both sides of the lever 711 increase the surface roughness and friction of the lever 711, significantly improving the user's grip stability during operation and effectively preventing hand slippage during the pulling of the lever 711. After the lever 711 is subjected to force, it drives the limit block 709 to overcome the elastic force of the spring 710, causing the limit block 709 to be pulled out from the limit grooves 706 at both ends of the rotating shaft 704. During this process, Spring 710 is compressed, storing elastic potential energy. Simultaneously, limiting block 709 compresses slide rod 708 within hollow tube 707, providing guidance and support for the movement of limiting block 709 and ensuring its stable extraction. After the limiting is released, rotating shaft 704, supported by round shaft 703, can rotate freely within the circular groove 702 of round block 701. Sliding ball 713, rotatably connected to the inner wall of circular groove 702, slides in contact with round shaft 703, transforming traditional surface contact into point contact. This significantly reduces friction during the rotation of round shaft 703, allowing rotating shaft 704 to move more freely. The rotation is more flexible and smooth, allowing users to easily rotate the lamp body 6 to the desired angle. When the rotating shaft 704 rotates, the fixed plate 714 and the lamp body 6, which are fixedly connected to it, also rotate synchronously. When the lamp body 6 rotates to the appropriate angle, the user releases the lever 711. At this time, the compressed spring 710 releases its elastic potential energy, generating a restoring force that pushes the limiting block 709 to move towards the rotating shaft 704. Under the action of the spring 710, the limiting block 709 re-inserts into the corresponding limiting groove 706 on the rotating shaft 704. The rotating shaft 704 is now fixed in a limiting position, thereby stabilizing the lamp body 6 at the target angle and achieving precise dimming. In summary, by setting the adjustment device 7, the cooperation between the circular shaft 703, the rotating shaft 704 and the limiting structure is achieved, which can realize the effect of multi-angle rotation of the lamp body 6. It can accurately cover the lighting needs of different directions. Whether it is used as a reading light to focus on a local area or as an ambient light to diffuse light, users can quickly adjust the illumination angle according to the actual scene, avoiding the problem of blind spots caused by the fixed direction of traditional lamps.

[0029] Working principle: When the user needs to adjust the height of the lamp body 6, they rotate the drive rod 83. Since one end of the drive rod 83 is rotatably connected to the second square plate 82, and the other end passes through the first square plate 81 and is threaded, when the user rotates the drive rod 83, according to the principle of thread transmission, the rotational motion of the drive rod 83 is converted into linear motion along the axial direction. The connecting plate 84, which is threaded to the drive rod 83, moves up and down along the threaded surface of the drive rod 83 under the drive of the drive rod 83. At the same time, the connecting plate 84 is embedded in the elongated hole 85 on the first support rod 2. The inner wall guides and limits the connecting plate 84, ensuring that it does not shift or shake during movement. Since the connecting plate 84 is fixedly connected to the lifting rod 4, its movement causes the lifting rod 4 to slide synchronously within the groove of the first support rod 2. The lifting rod 4 is then fixedly connected to the second support rod 3, which in turn is fixed to the U-shaped frame 5. This ultimately achieves synchronous lifting of the U-shaped frame 5 and the lamp body 6. Throughout the lifting process, the curtain 86 fixed to the inner wall of the elongated hole 85 plays a crucial protective role. Because the curtain 86 is foldable and its… Both sides are fixed to the inner wall of the elongated hole 85 and the connecting plate 84 respectively, so they will expand and contract with the raising and lowering of the connecting plate 84, so that the curtain 86 always tightly covers the gap of the elongated hole 85, effectively blocking dust and foreign objects from entering the slide groove, preventing these debris from contaminating or jamming the lifting rod 4, drive rod 83 and other components, ensuring the smooth operation and service life of the lifting device 8. The rubber wear-resistant pad 87 fixed to the bottom surface of the base 1 provides stable support for the lamp with the high friction of the rubber material itself. The wear-resistant pad 87 increases the friction between the lamp and the placement surface, preventing the lamp from being damaged during use. To prevent the lamp from sliding and shifting due to external impacts, slight vibrations, or uneven surfaces, and to ensure the stable placement of the lamp, the lifting device 8 is set up to achieve a threaded transmission structure between the drive rod 83 and the connecting plate 84. This allows users to precisely adjust the height of the lamp body 6 according to the actual usage scenario. In a living room with a high ceiling, the lamp can be raised to achieve uniform lighting over a large area. In a compact study or workspace, lowering the lamp height can concentrate the light in a localized area, meeting the differentiated lighting needs of different spaces and avoiding the problem of wasted light or insufficient lighting caused by a fixed lamp height.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
