In this document, the device is provided with a fixing ear and a fixing screw. When installing the LED lamp bead, the mounting ear of the LED lamp bead is made to be close to the mounting surface, and a screwdriver is used to tighten the cross slot of the fixing screw so that the fixing screw is screwed into the mounting surface to stably install the fixing ear.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 5 As shown, an LED lamp bead with a built-in driver IC includes a substrate 1 and a lamp bead seat 16, characterized in that: a plurality of mounting grooves 2 are opened on the top of the substrate 1, and the bottom of the inner wall of the mounting groove 2 is rotatably connected to a card column 3, and the outer wall of the card column 3 is opened with a first mounting hole 6, and the inner wall of the first mounting hole 6 is fixedly connected to a slide rod 7, and the outer wall of the circumference of the slide rod 7 is sleeved with a second spring 8, and the outer wall of the circumference of the slide rod 7 is sleeved with a slidable connecting ring 9, and the outer wall of the circumference of the connecting ring 9 is symmetrically connected to two first hinge seats 10, and the inner walls of the two first hinge seats 10 are rotatably connected to connecting arms 11, and the ends of the two connecting arms 11 are rotatably connected to the second hinge seat 12, the inner wall of the first mounting hole 6 is symmetrically connected to two rotating shafts 13, and the outer walls of the two rotating shafts 13 are fixedly connected to card arms 14, and the outer walls of the two card arms 14 are respectively fixedly connected to the second hinge seat 12, one end of the second spring 8 is fixedly connected to the inner wall of the card column 3, and the other end of the second spring 8 is fixedly connected to the bottom of the connecting ring 9.

[0022] like Figure 1 and Figure 4 As shown, a plurality of second mounting holes 17 are provided on the top of the lamp bead holder 16, and two extension holes 18 are provided on the inner wall of each of the second mounting holes 17. The top of the clamping column 3 passes through the second mounting hole 17 and extends above it, and the top of the clamping arm 14 passes through the extension hole 18 and extends above it.

[0023] like Figure 3 As shown, the outer wall of the clamp arm 14 is provided with an arc surface 15, and the arc surface 15 is located at the outer edge of the bottom end of the clamp arm 14. By setting the arc surface 15, the friction between the clamp arm 14 and the inner wall of the lamp bead holder 16 can be reduced during installation, thereby achieving the purpose of facilitating installation, reducing the wear between the structures, and increasing the service life of the structure, so that the device can be repeatedly disassembled and assembled.

[0024] like Figure 3 and Figure 4 As shown, a guide groove 19 is provided at the bottom of the second mounting hole 17 and the two connected extension holes 18. The guide groove 19 is a truncated cone structure. The outer walls of the circumferences of multiple clamping columns 3 are all sleeved with first springs 4, and the outer walls of the circumferences of the clamping columns 3 are all sleeved with sliding trays 5. The tray 5 is a truncated cone structure, and the top of the tray 5 abuts against the inner wall of the guide groove 19. One end of the first spring 4 is fixedly connected to the bottom of the tray 5, and the other end of the first spring 4 is fixedly connected to the inner wall of the base plate 1. Under the elastic force of the first spring 4, the tray 5 is upwardly clamped into the inside of the guide groove 19, which can further limit the lamp bead holder 16. At the same time, the top of the lamp bead holder 16 can be closely contacted with the clamping arm 14, thereby improving the stability of the installation of the lamp bead holder 16. By providing the guide groove 19, it is easy to quickly align the top of the clamping column 3 with the second mounting hole 17, so that the top of the clamping column 3 can quickly slide along the guide groove 19 to the inside of the second mounting hole 17, thereby achieving the purpose of easy installation.

[0025] like Figure 5 As shown, a lamp bead cover 20 is installed on the top of the lamp bead holder 16, and a luminous bead ball 21 is fixedly installed inside the lamp bead cover 20. An IC chip 22 is fixedly installed inside the luminous bead ball 21. The IC chip 22 is used to improve the reliability of signal transmission of the LED lamp bead at the application end and is not easy to be damaged. The upper end of the IC chip 22 is electrically connected to a luminous bead point 23. By providing the IC chip 22, the IC chip 22 is installed inside the luminous bead ball 21, and the upper end of the IC chip 22 is electrically connected to the luminous bead point 23. The luminous bead point 23 and the IC chip 22 are cleverly integrated into the luminous bead ball 21, so that it forms a complete LED integrated circuit, eliminating the carrier required for a single LED, simplifying the manufacturing process, reducing the number of components, reducing production costs, and improving product production efficiency and yield.

[0026] Working principle: Press the lamp bead holder 16 downward, so that the top ends of the multiple clamping columns 3 on the base plate 1 slide upward along the guide groove 19, the second mounting hole 17 and the extension hole 18 respectively, until the clamping column 3 penetrates the base plate 1, and the two clamping arms 14 on the clamping column 3 are located above the base plate 1. By rotating the clamping column 3, the position of the clamping arm 14 is adjusted, and the tray 5 is squeezed upward by the multiple first springs 4. The tray 5 squeezes the inner wall of the guide groove 19 at the bottom of the lamp bead holder 16 upward, so that the top of the lamp bead holder 16 can be squeezed and contacted with the bottom of the clamping arm 14, so that the lamp bead holder 16 can be quickly installed, thereby quickly fixing the LED lamp bead;

[0027] During installation, when the clamping arm 14 is aligned with the extension hole 18, the clamping arm 14 is squeezed toward the inside of the first mounting hole 6, and the clamping arm 14 rotates toward the first mounting hole 6 with the rotating shaft 13 as the center. At the same time, the connecting arm 11 pushes the connecting ring 9 to slide downward along the slide rod 7 and compresses the second spring 8 downward. When the clamping arm 14 moves to above the lamp bead holder 16, under the elastic force of the second spring 8, the connecting ring 9 pushes the clamping arm 14 to flip outward through the connecting arm 11, thereby limiting the lamp bead holder 16, thereby further increasing the installation speed.

[0028] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
