AI Technical Summary
Existing COB LED strips are prone to adhesive layer peeling off at the edges due to stress when bent, affecting the fixing effect and overall integrity.
The heat-conducting components include a heat-conducting main body and an extension section. By setting a branch groove and a main groove at the bottom of the light strip body, the heat-conducting main body and extension section made of metal are bent and shaped, and multiple light strips are connected as a whole through the splicing structure's grooves and wings.
This avoids the tape from falling off due to direct bending of the LED strip edges, enhances the shaping effect and overall integrity, and improves heat dissipation performance and the lifespan of the LED beads.
