[0028] Please refer to Figures 1-8, the present invention provides a technical solution: an LED lamp bead assembly and an LED light strip, including a light strip 1, on which a plurality of connecting plates 4 are arranged, and a plurality of lamp beads 5 are fixedly installed on each connecting plate 4.

A plurality of groups of card slots 33 are formed on each conductive strip a32, and each card slot 33 communicates with each square groove 30 respectively. A conductive block a27 is arranged in each card slot 33, and a connecting groove 28 is formed on each conductive block a27. A connecting column 34 is movably connected in each circular groove 29, and each connecting column 34 movably penetrates through two conductive strips a32 respectively, and each connecting column 34 is movably connected with each connecting groove 28 respectively. Two half-frames 8 are arranged on the light strip 1, and a flexible board 10 is fixedly installed on each half-frame 8. A conductive strip b21 is fixedly installed in each flexible board 10, and three small grooves 22 are formed on each conductive strip b21.

By pulling out the six connecting columns 34 corresponding to one of the connecting plates 4, the connecting plate 4 can be moved upward for disassembly, so that the user can disassemble the corresponding lamp group, which is convenient for the user to replace the lamp group. At the same time, by inserting the conductive column 11 into the corresponding circular groove 29, the conductive column 11 will pass through the connecting groove 28 and the conductive strip a32. After the user connects the two half-frames 8 to each other, the light strip 1 can be powered on by connecting with the two conductive blocks b26 through a wire. Thus, when installing, the user can cut the light strip 1 according to needs, and then use the half-frame 8 to connect with the cut end, which is convenient for the user to adjust the length of the light strip 1. A rubber ring 24 is fixedly installed in each circular groove 29, a short column a12 is fixedly installed on each conductive column 11, and an annular wall groove a23 is formed on each short column a12. After inserting the conductive column 11 into the circular groove 29, the short column a12 will be driven into the circular groove 29, and by squeezing the rubber ring 24, it will be sleeved on the annular wall groove a23, which can improve the friction force to prevent the conductive column 11 from falling off.

At the same time, the cooperation between the clamping strip 15 and the transverse groove 2 can prevent the two mutually fixed half-frames 8 from falling off. Semi-cylindrical boxes 9 are fixedly installed on both the upper and lower sides of the two half-frames 8. Semi-cylindrical grooves 37 are provided on all four semi-cylindrical boxes 9. Two notches 16 are provided on all four semi-cylindrical grooves 37. Two round boxes 13 are provided on both the upper and lower sides of the two half-frames 8.

Two movable blocks 19 are fixedly installed on both the two round boxes 13. Small blocks 38 are fixedly installed on all four movable blocks 19. Through grooves 18 are provided on all four semi-cylindrical boxes 9. Grooves 20 are provided on the side walls of each through groove 18. Each groove 20 communicates with each semi-cylindrical groove 37 respectively. After the two half-frames 8 are fitted to each other, the movable blocks 19 on the round boxes 13 are aligned with the corresponding notches 16, and the round boxes 13 are pressed into the semi-cylindrical boxes 9. Then, the round boxes 13 are pressed and rotated so that the small blocks 38 on the round boxes 13 are aligned with the corresponding through grooves 18, and then the round boxes 13 are released. In this way, the elastic force of the pressure spring 17 will drive the round boxes 13 to move so that the small blocks 38 enter the through grooves 18. In this way, the two semi-cylindrical boxes 9 can be prevented from separating front and back, and the two half-frames 8 can be fixed, thus facilitating the user to install and disassemble the two half-frames 8.

[0029] During use, the first step: After pulling out the six connecting columns 34 corresponding to one of the connecting plates 4, the connecting plate 4 can be moved upward for disassembly, so that the user can disassemble the corresponding lamp group, which facilitates the user to replace the lamp group. At the same time, by inserting the conductive column 11 into the corresponding round groove 29, the conductive column 11 will pass through the connecting groove 28 and the conductive strip a32. After the user connects the two half-frames 8 to each other, the light strip 1 can be powered on by connecting with the two conductive blocks b26 through wires. Therefore, when installing, the user can cut the light strip 1 according to needs, and then use the half-frame 8 to connect with the cut end, so as to facilitate the user to adjust the length of the light strip 1.

[0030] The second step: After inserting the conductive column 11 into the round groove 29, the short column a12 will be driven into the round groove 29.

[0031] Step 3: After inserting the connecting column 34 into the circular groove 29, it will drive the short column b35 into the circular groove 29. By squeezing the rubber ring 24, it will be sleeved on the annular wall groove b36. Together with the sticker 3, it can prevent the connecting column 34 from falling off and causing the connecting plate 4 to separate from the lamp group.

[0032] Step 4: The fixing groove 14 on the conductive sheet 6 can facilitate users to connect power transmission tools such as wires. At the same time, the cooperation between the clamping strip 15 and the horizontal groove 2 can prevent the two half-frames 8 fixed to each other from falling off.

[0033] Step 5: After fitting the two half-frames 8 together, align the movable block 19 on the round box 13 with the corresponding notch 16 and press the round box 13 into the semi-circular box 9. Then press and rotate the round box 13 so that the small block 38 on the round box 13 aligns with the corresponding through groove 18 and then release the round box 13. In this way, the elastic force of the compression spring 17 will drive the round box 13 to move so that the small block 38 enters the through groove 18, which can prevent the two semi-circular boxes 9 from separating front and back, and thus fix the two half-frames 8, facilitating users to install and disassemble the two half-frames 8.
