[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 and Figure 5 As shown in this embodiment, a breakage-resistant LED light strip includes a flexible circuit board 1, with LED beads 2 fixedly connected to the top of the flexible circuit board 1, a heat-conducting sheet 3 fixedly connected to the top of the flexible circuit board 1, a protective rubber sheet 4 fixedly connected to the top of the flexible circuit board 1, a heat dissipation groove 5 formed at the bottom of the protective rubber sheet 4, a mounting groove 6 formed at the bottom of the protective rubber sheet 4, a light-transmitting groove 7 formed at the top of the mounting groove 6, a protrusion 8 fixedly connected inside the mounting groove 6, and a heat dissipation hole 9 formed at the top of the protective rubber sheet 4.

[0024] By adding a protective rubber plate 4 to the flexible circuit board 1, the light strip is protected during use, preventing it from being damaged by contact with other objects. A heat-conducting sheet 3 is provided on the flexible circuit board 1 to conduct the heat generated by the light strip during operation. The heat is then conducted through the heat dissipation groove 5 to the heat dissipation hole 9, thereby dissipating it to the outside and preventing the light strip from overheating. When the light strip is bent, it can deform through the protrusions 8 in the mounting groove 6. The protrusions 8 abut against each other, which can achieve rebound. The protrusions 8 are made of transparent material to ensure that light can pass through. A conical light-transmitting groove 7 is provided on the mounting groove 6 to achieve light diffusion and increase the illumination area of ​​the LED light strip.

[0025] The number of LED beads 2 is set to be multiple, and multiple LED beads 2 are located inside the mounting groove 6. The protective rubber plate 4 is made of transparent rubber material. The heat dissipation groove 5 and the heat dissipation hole 9 form a heat dissipation channel. The light transmission groove 7 adopts a conical structure.

[0026] The bottom end of the flexible circuit board 1 is fixedly connected with a warp thread 10 and a weft thread 11, and a potting ring 12 is fixedly connected to the surface of the weft thread 11.

[0027] By setting multiple warp threads 10 and weft threads 11 on the flexible circuit board 1 to form a grid structure, the deformation capability of the flexible circuit board 1 is guaranteed. Encapsulating adhesive is applied to the anti-fracture layer 13 and the surface of the flexible circuit board 1 to form an encapsulating ring 12 to seal them, thereby providing insulation protection for the light strip.

[0028] The number of meridians 10 and parallels 11 is set to multiple, and the multiple meridians 10 and parallels 11 form a grid structure. The potting ring 12 is located on the surface of the flexible circuit board 1.

[0029] The bottom end of the weft thread 11 is fixedly connected to an anti-fracture layer 13. The anti-fracture layer 13 has an installation hole 14 inside, and a reinforcing rib 15 is provided inside the installation hole 14.

Furthermore, an inclined abutment surface 17 is provided on the anti-fracture layer 13. When the light strip is bent, the abutment surface 17 undergoes relative displacement and abuts against each other. At the same time, the convex rib plate 18 in the movable cavity 16 is squeezed and slides relative to each other, thereby deforming the light strip and preventing breakage during bending.

[0032] The number of movable cavities 16 is set to multiple, and the multiple movable cavities 16 adopt a trapezoidal structure. The contact surface 17 is set to a slope. The number of protruding ribs 18 is set to three, and the three protruding ribs 18 are semi-circular in shape.

[0033] This utility model provides a breakable LED light strip, the specific working principle of which is as follows:

[0034] In use, the protective rubber plate 4 is fixed to the flexible circuit board 1 with adhesive, and potting compound is applied to the surface of the anti-fracture layer 13 and the flexible circuit board 1 to form a potting ring 12 to seal it, thereby providing insulation protection for the light strip. A heat-conducting sheet 3 is provided on the flexible circuit board 1 to conduct the heat generated by the light strip during operation and conduct it through the heat dissipation groove 5 to the heat dissipation hole 9, thereby dissipating it to the outside and preventing the light strip from overheating. When the light strip is bent, the protrusions 8 in the mounting groove 6 can deform and the protrusions 8 can rebound by contacting each other. The anti-fracture layer 13 can generate relative displacement through the contact surface 17 and abut against each other. At the same time, the convex rib plate 18 in the movable cavity 16 is squeezed and slides relative to each other, thereby deforming the light strip and preventing breakage during bending.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
