[0032] Reference Figures 1 to 6 The first embodiment of the present application proposes a bendable light strip, which includes: a connecting copper wire 1 and a plurality of light-emitting modules 2; the connecting copper wire 1 includes a plurality of embedded wire segments 11 and a plurality of bendable wire segments 12, each of the embedded wire segments 11 is arranged in the light-emitting module 2 and is electrically connected to the light-emitting module 2; every two light-emitting modules 2 are arranged with a gap between each other, and the two ends of each bendable wire segment 12 are respectively connected to two adjacent embedded wire segments 11.

[0033] Specifically, both ends of the bendable line segment 12 extend to form an embedded line segment 11 , or both ends of the bendable line segment 12 extend to form an embedded line segment 11 , which extend to connect to external wires.

[0034] In this embodiment, the embedded wire segments 11 are electrically connected to the light-emitting modules 2, and the embedded wire segments 11 are positioned within the light-emitting modules 2, thereby enhancing the connection stability between the embedded wire segments 11 and the light-emitting modules 2. Furthermore, the spacing between each two light-emitting modules 2 and the bendable wire segments 12 allow the two light-emitting modules 2 to bend relative to each other, thus enabling the bendable light strip to achieve a bendable function. Furthermore, the two light-emitting modules 2 are electrically connected. In summary, the bendable light strip of the present invention achieves a bendable function, allowing users to easily bend and deform the light strip to suit decorative patterns.

[0035] Specifically, the bendable light strip can achieve positive bending (see Figure 5 ) and lateral bending (see Figure 6 ).

[0036] Specifically, a connecting copper wire 1 is formed by twisting multiple copper wires, and two connecting copper wires 1 are provided between the two light-emitting modules 2, one is the positive connecting copper wire 1, and the other is the negative connecting copper wire 1. The two ends of the positive connecting copper wire 1 are respectively electrically connected to the positive poles of the two light-emitting modules 2, and the two ends of the negative connecting copper wire 1 are respectively electrically connected to the negative poles of the two light-emitting modules 2.

[0038] In this embodiment, the lamp bead module 23 is electrically connected to the embedded wire segment 11 connected to the copper wire 1 through the lamp bead base 22; then the lamp bead base 22 is embedded and fixed on the fixed wire base 21, and the embedded wire segment 11 is arranged between the fixed wire base 21 and the bottom of the lamp bead base 22, thereby enhancing the reliability of the electrical connection between the embedded wire segment 11 and the lamp bead module 23, thereby ensuring that the lamp bead module 23 can emit light normally, and then the bendable connection and electrical connection between the two light-emitting modules 2 are realized through the bendable wire segment 12, which not only makes the light strip more flexible as a whole and facilitates bending or folding as needed, but also ensures that the electrical connection between each light-emitting module 2 is not affected.

[0039] In summary, the bendable light strip of the present invention can not only realize the bendable function, but also enhance the contact reliability of the electrical connection between the light emitting module 2 and the connecting copper wire 1 to avoid poor contact.

[0040] Reference Figures 1 to 4 The wire fixing base 21 is provided with a first groove 211 and a second groove 212 . The second groove 212 is provided at the bottom of the first groove 211 . The lamp bead base 22 is embedded and fixed in the first groove 211 , and the embedded wire segment 11 is embedded in the second groove 212 .

[0041] In this embodiment, the first groove 211 is used to limit the position of the lamp bead base 22 to prevent the embedded wire segment 11 from being easily disconnected from the lamp bead base 22, and then the second groove 212 is used to limit and fix the embedded wire segment 11 to prevent the embedded wire segment 11 from being offset from the connection with the lamp bead base 22, thereby preventing the embedded wire segment 11 from being disconnected from the lamp bead base 22.

[0042] Specifically, two second grooves 212 are provided, and the two second grooves 212 are used to embed and fix the positive electrode connecting copper wire 1 and the negative electrode connecting copper wire 1 respectively.

[0044] In this embodiment, the limiting ridge 213 is engaged with the limiting groove 221 to further confine the lamp bead base 22 within the first groove 211, thereby further improving the electrical connection stability between the embedded wire segment 11 and the lamp bead base 22.

[0045] Specifically, the axis of the limiting rib 213 is perpendicular to the bottom of the first groove 211, and the axis formed between the two notches of the second groove 212 is parallel to the side groove surface of the first groove 211 and perpendicular to the axis of the limiting rib 213. In summary, the position of the embedded wire segment 11 is limited in the radial and axial directions to ensure that the lamp base 22 is stably embedded in the first groove 211, thereby ensuring a stable connection between the embedded wire segment 11 and the lamp base 22, avoiding the problem of disconnection.

[0046] Reference Figures 1 to 4 A welding groove 214 is provided in the middle of the side of the wire fixing base 21 and extends toward the middle of the wire fixing base 21 .

[0047] In this embodiment, the welding groove 214 is filled with solder, which wraps the embedded wire segment 11 and the lamp bead base 22 together, thereby achieving welding between the embedded wire segment 11 and the lamp bead base 22. The welding groove 214 is located in the middle of the side of the wire fixing base 21, thereby achieving welding between the middle of the embedded wire segment 11 and the middle of the lamp bead base 22. The weld formed by the welding groove 214 can also be limited in position, thereby further improving the stability of the electrical connection between the embedded wire segment 11 and the lamp bead base 22.

[0048] In some embodiments, both ends of the embedded wire segment 11 are welded to the lamp bead base 22 to further improve the electrical connection stability between the embedded wire segment 11 and the lamp bead base 22 .

[0050] In this embodiment, the first clearance hole 31 is used to limit the wire fixing base 21 and the lamp bead base 22, the second clearance hole 32 is used to avoid the lamp bead module 23, and the avoidance gap 33 is used to prevent the lamp housing 3 from crushing the lamp bead module 23 when the lamp housing 3 is under pressure.

[0051] In some embodiments, an operation limiting groove 215 is provided at the bottom of the wire fixing base 21 ; in this embodiment, the lamp housing 3 is integrally injection molded, and the operation limiting groove 215 is used to mate with the operation base of the injection molding mechanism.

[0052] Specifically, the operation limit groove 215 is first embedded in the operation position of the injection molding mechanism, and the injection molding mechanism injection molds the lamp housing 3 around the circumference of the light emitting module 2. Several light emitting modules 2 and connecting copper wires 1 are all wrapped inside the lamp housing 3.

[0053] Furthermore, the top of the lamp housing 3 is made of a transparent material so as not to hinder the light diffusion of the light emitting module 2 . The entire lamp housing 3 is made of a bendable soft silicone material to achieve the bendable function of the bendable light strip.

[0054] Reference Figures 1 to 2 The aperture of the second evacuation hole 32 is smaller than the aperture of the first evacuation hole 31 .

[0055] In this embodiment, the aperture of the second clearance hole 32 is smaller than the aperture of the first clearance hole 31, that is, the bottom hole wall of the second clearance hole 32 is arranged in the middle of the top hole wall of the first clearance hole 31; so that the hole wall of the first clearance hole 31 can press the lamp bead base 22 down and confine it in the wire fixing base 21.

[0056] Reference Figures 1 to 2 The top hole wall of the second clearance hole 32 is in an arch shape, and the light-emitting end of the lamp bead module 23 faces the top hole wall of the second clearance hole 32.

[0059] In this embodiment, the light expansion hole 34 is used to diffuse light and improve light output. It can also reduce the pressure on the top surface of the lamp housing 3 that may damage the lamp bead module 23, thereby protecting the lamp bead module 23.

[0060] Reference Figures 1 to 2 The light expansion hole 34 includes a first hole wall 341 and a second hole wall 342. The first hole wall 341 and the second hole wall 342 are enclosed and connected.
