[0002] LED lights, also known as light-emitting diodes, are solid-state light sources that emit light when excited by an electric current through semiconductor materials. Compared with traditional incandescent and fluorescent lamps, LED lights have advantages such as high energy efficiency, long lifespan, small size, and fast response speed, and are therefore widely used in the lighting field. The foundation of LED technology is laid by semiconductor physics. The earliest LED was invented in 1962 by scientists such as Nick Holney in the United States. The initial light emitted was red. In the 1970s, researchers began to explore different materials for LED manufacturing, such as gallium arsenide. The application of LEDs was mainly limited to indicator lights and digital displays. The invention of blue LEDs marked a breakthrough in LED technology, making the combination of the three primary colors possible, thus realizing the manufacturing of white LEDs. Now that LED technology is mature, it is widely used in the lighting industry and is gradually replacing traditional incandescent and fluorescent lamps.

[0003] However, some adjustable LED lamp holders have a relatively simple structure. They usually change the lighting direction by adjusting the orientation of the rotating LED lamp holder. The light beam is illuminating at a planar angle, which can easily cause people to be illuminated, resulting in glare. They are difficult to meet the special needs of adjusting the lighting by changing the height of the LED lamp and the position of the light beam in all directions in real time. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is an adjustable LED lamp holder, including a support base 1, on which an adjustment mechanism 2 and a rotation mechanism 3 are provided;

[0028] The adjustment mechanism 2 includes a flipping component and an adjustment component. The flipping component includes a support rod 21 mounted on a support base 1. A first joint block 22 is hinged to the bottom end of the support rod 21, and a second joint block 23 is hinged to the top end of the support rod 21. The bottom surface of the first joint block 22 is fixedly connected to the top surface of the support base 1. A first sliding groove 24 is provided on the inner wall of the support rod 21, and a slider 25 is slidably connected to the inner wall of the first sliding groove 24.

[0029] Among them, such as Figure 3 and Figure 4 As shown, the adjustment assembly includes several first springs 26 fixedly connected to the back of the button 27. The ends of the first springs 26 are all fixedly connected to the inner wall of the first slide groove 24. Two first locking rods 28 are fixedly connected to the front of the button 27. Several first slots 29 are opened on the front of the first joint block 22 and the second joint block 23. The front ends of the two first locking rods 28 extend to the inner wall of the first slots 29 and are slidably connected to the two first slots 29.

[0030] By setting the adjustment mechanism 2, the elastic force of several first springs 26 is utilized. By pressing the button 27 and flipping the first joint block 22 and the second joint block 23 hinged to the support rod 21, the height and vertical tilt angle of the LED light 39 can be adjusted. Combined with the rotation adjustment of the rotating mechanism 3, the personnel can adjust the light illumination angle of the LED light 39 in all directions in real time. The adjustment range is relatively wide, which to a certain extent avoids the light from dazzling the personnel.

[0031] Among them, such as Figure 2 and Figure 5As shown, a second sliding groove 34 is opened on the inner wall of the rotating drum 33. A sliding ring 35 is slidably connected to the inner wall of the second sliding groove 34. The inner wall of the sliding ring 35 is slidably connected to the outer wall of the limiting rod 31. The self-locking assembly includes a second spring 36 fixedly connected to the right side of the sliding ring 35. The right end of the second spring 36 is fixedly connected to the inner wall of the second sliding groove 34. A toggle button 37 is fixedly connected to the outer wall of the sliding ring 35. The outer wall of the toggle button 37 is slidably connected to the inner wall of the second sliding groove 34. A second locking rod 38 is fixedly connected to the left side of the toggle button 37. The left end of the second locking rod 38 extends to the inner wall of the upper second locking groove 32 and is slidably connected to the second locking groove 32. An LED light 39 is fixedly connected to the left end of the rotating drum 33.

[0032] By setting up the rotating mechanism 3, the elastic force of the second spring 36 is utilized, and the operator can limit and fix the angle of the rotating drum 33 after rotation by turning the knob 37. In conjunction with the adjustment mechanism 2, the angle adjustment and orientation of the LED light 39 can be fixed. The mechanical structure design is simple and quick to operate, further improving the practicality of the device.

[0033] A specific application of this embodiment is as follows: LED lamp 39 consists of a semiconductor chip, a package, and electrodes. The semiconductor chip is usually composed of a PN structure, in which P-type semiconductors and N-type semiconductors are combined to form a PN junction. A forward voltage is applied to both ends to allow current to flow. When an external power supply provides a forward voltage to the LED lamp, current flows into the LED's semiconductor chip. At the PN junction, holes in the P-type semiconductor and free electrons in the N-type semiconductor move towards the junction region respectively. Electrons flow from the N-type region to the P-type region, while holes flow from the P-type region to the N-type region. When electrons recombine, excess energy is released and radiated in the form of photons. This is the process of LED light emission.

[0034] By setting the adjustment mechanism 2, when a person needs to adjust the height or illumination direction of the LED light 39, pressing the button 27 causes the slider 25 to slide within the first groove 24, compressing several first springs 26. Simultaneously, the slider 25 causes its two first locking rods 28 to disengage from the first locking slot 29 and slide into the first groove 24. Then, the person can adjust the height of the LED light 39 fixed on the second joint block 23 by rotating the rotation angle between the first joint block 22 and the support rod 21 and the second joint block 23, thus adjusting the illumination angle of the LED light 39. After adjustment, releasing the button 27 allows the slider 25 to move under the elastic restoring force of the several first springs 26. The two first locking rods 28 slide into specific first locking slots 29, limiting and fixing the rotation angle of the support rod 21, the first joint block 22, and the second joint block 23. This prevents the rotation angle from shifting due to the gravity of the LED light 39. By utilizing the elastic force of several first springs 26, personnel can adjust the height and vertical rotation angle of the LED light 39 by pressing the button 27 and rotating the first joint block 22 and the second joint block 23 hinged to the support rod 21. Combined with the rotation adjustment of the rotating mechanism 3, this allows personnel to adjust the light illumination angle of the LED light 39 in all directions in real time. The adjustment range is relatively wide, which to some extent avoids the light from glaring on personnel.

[0035] By setting up a rotating mechanism 3, which works in conjunction with the adjusting mechanism 2 to complete the height and vertical flipping, the sliding ring 35 can be slid in the second slide groove 34 and the second spring 36 can be compressed by turning the knob 37. This causes the second locking rod 38 to disengage from the second locking groove 32 and slide into the second slide groove 34. At this time, the operator can rotate the rotating drum 33 to rotate the LED light 39 around the limiting rod 31 to adjust the rotation of the LED light 39. After releasing the knob 37, the elastic restoring force of the second spring 36 pushes the sliding ring 35 to slide in the second slide groove 34, causing the second locking rod 38 to slide into the specific second locking groove 32, thus completing the limiting fixation of the LED light 39 after rotation adjustment. This realizes that by using the elastic force of the second spring 36, the operator can manually limit and fix the angle of the rotating drum 33 after rotation by turning the knob 37. In conjunction with the adjusting mechanism 2, the angle adjustment and orientation of the LED light 39 can be fixed. The mechanical structure design is simple and quick to operate, further improving the practicality of the device.
