[0022] Please see Figure 1 and Figure 5The rectangular groove (292) at the bottom of the second rectangular plate (297) is used to provide installation and rotation space for the drive shaft (291) and the second round rod (299) rotatably connected to it.

[0023] It should also be noted that a rectangular rod 212 is rotatably connected to the top of the second U-shaped rod 22, and a circular piece 213 is fixedly connected to the top of the rectangular rod 212. One end of the rectangular rod 212 is in contact with the light-emitting plate 1.

[0025] It should also be noted that the light-emitting plate 1 includes several evenly arranged circular holes 12 on its top. Several evenly arranged LED beads 11 are also fixedly connected to the top of the light-emitting plate 1. Each LED bead 11 has a rectangular rounded corner hole 23 at its bottom on the top of the light-emitting plate 1. A second slide rail 222 is fixedly connected to the bottom of each rectangular rounded corner hole 23. A second round tube assembly 215 is slidably connected to the outside of each second slide rail 222. A second slide groove 217 is opened at the bottom of the second round tube assembly 215 and is slidably connected to the second slide rail 222. A second rotating groove 218 and a first rotating groove 216 are opened at the top of the second slide groove 217 on the inner side of the second round tube assembly 215. The second rotating groove 218 and the first rotating groove 216 are connected and have the same depth. The height of the first rotating groove 216 is twice that of the second rotating groove 218.

[0026] Please see Figure 1 and Figure 7 When the spacing of the LED beads 11 needs to be adjusted, the second slide rail 222 slides with the LED beads 11. The first rotating groove 216 and the second rotating groove 218 opened on the inner side of the second round tube assembly 215 rotate and cooperate with the sliding block 220. The second sliding groove 217 opened at the bottom of the second round tube assembly 215 is used to slide on the outer side of the second slide rail 222 for adjusting the position of the LED beads 11.

[0027] It should also be noted that a circular slide rod 221 is rotatably connected to the inner side of the second circular tube assembly 215, and a sliding block 220 is fixedly connected to the outer side of the bottom of the first slide rail 211. The sliding block 220 is engaged with the second rotating groove 218. A spring 214 is fixedly connected to the bottom of the circular slide rod 221, and a circular washer 219 is fixedly connected to the bottom of the spring 214. The bottom of the circular washer 219 slides in contact with the second slide rail 222.

[0028] Please see Figure 1 , Figure 6 and Figure 7The outer side of the circular slide bar 221 slides in contact with the inner side of the second circular tube assembly 215, which can be used to adjust the height of the lamp bead 11. The spring 214 can reduce the pressure on the circular pad 219 when the lamp bead 11 is raised, so that the second circular tube assembly 215 can slide smoothly on the second slide rail 222.

[0029] It should also be noted that bearings 26 are fixedly connected to the top of both sides of the light-emitting plate 1. A first round tube assembly 27 is fixedly connected to the inside of each bearing 26. A second bolt 28 is rotatably connected to the outside of the first U-shaped tube 21 and the second U-shaped rod 22. The second bolt 28 is fixedly connected to the first round tube assembly 27. There are two symmetrical cooling fans 25 at the bottom of the light-emitting plate 1, which are fixedly connected to the bottom of the light-emitting plate 1 by a first bolt 24.

[0030] Please see Figure 1 , Figure 2 and Figure 4 When the light-emitting plate 1 needs to be rotated, the bearing 26 is fixedly connected to the first round tube assembly 27 and fixedly connected to the first U-shaped tube 21 and the second U-shaped rod 22 through the second bolt 28, which can be used to rotate the light-emitting plate 1. The cooling fan 25 fixedly connected to the bottom of the light-emitting plate 1 can be used to blow away the heat generated when the lamp bead 11 emits light, so as to avoid the light-emitting effect being affected by the excessive height. The cooling fan 25 can improve the heat dissipation efficiency through the round hole 12 opened on the light-emitting plate 1. Detailed implementation method: When it is necessary to fix the light-emitting plate 1, the width of the second U-shaped rod 22 and the first U-shaped tube 21 installed on the inner side of the first U-shaped tube 21 can be adjusted by sliding the second U-shaped rod 22 and the first U-shaped tube 21 to match the width of the light-emitting plate 1. Then, the second U-shaped rod 22 and the first U-shaped tube 21 are fixedly connected to the light-emitting plate 1 by the second bolt 28. The bearing 26 can be used to flip the light-emitting plate 1. After the light-emitting plate 1 is flipped, the rectangular rod 212 can be rotated to make one end of the rectangular rod 212 contact the light-emitting plate 1 or the cooling fan 25 to achieve the limit of the light-emitting plate 1. After the U-shaped tube 21 is repositioned, the fastening assembly 29 can be rotated on the rectangular block 294 by tightening the third bolt 295. During continuous rotation, a rectangular piece 296 and a rectangular piece 296 fixedly connected to its bottom can be pushed into the U-shaped tube 21. Pressure can also be continuously applied to the second rectangular piece 297. After being subjected to pressure, the top of the second rectangular piece 297 will rotate on the rotating shaft 293, and the bottom will push the second round rod 299 into the U-shaped tube 21 until the second round rod 299 and the rectangular piece 296 contact the U-shaped tube 21 to achieve a fastening effect. This achieves the fastening effect of fastening component 29 on U-shaped rod 22 and U-shaped tube 21. When it is necessary to adjust the width between U-shaped rod 22 and U-shaped tube 21, simply unscrew bolt 3 295 to move round rod 298 and round rod 299 away from U-shaped tube 21. When it is necessary to adjust the distance of LED bead 11, the sliding block 220 is usually in contact with rotating groove 218. When it is necessary to adjust the spacing of LED bead 11, simply rotate LED bead 11 to drive the bottom round sliding rod 221 to rotate. When the sliding block 220 rotates to rotating groove 216, spring 214... The sliding block 220 will be pushed upwards. At this time, the force of the spring 214 on the circular pad 219 will be reduced, making the sliding effect of the second round tube assembly 215 on the second slide rail 222 more obvious. At this time, the spacing between the lamp beads 11 can be adjusted by sliding the second round tube assembly 215 on the second slide rail 222. After the adjustment is completed, simply press the lamp bead 11 and then rotate the sliding block 220 into the first rotating groove 216, so that the sliding block 220 is engaged with the first rotating groove 216 by the elastic force of the spring 214. The circular pad 219 increases the friction with the second slide rail 222 to limit the position of the lamp bead 11.
