Abstract: Disclosed are a new silicone cold-extrusion lamp belt and its manufacturing method. The manufacturing method includes the following steps. S10: Select a PCB and use the PCB as a substrate. S20: Set LED lamp bead spot-welding units arranged in an array formed on the substrate to obtain a target board. S30: Extrude a slurry which is formed by a food-grade silicone and coat the slurry on an outer surface of the target board to form a lamp skin. S40: Cut the target board into at least one lamp belt substrate. S50: Heat and bake the lamp belt substrate to obtain a lamp belt. This disclosure has the advantages of feasible design, low manufacturing cost, high resistance on cracking, wearing, yellowing, high/low temperature, good fire resistance, environmental friendly and harmless to human safety, high transparency, high light emitting efficiency of the lamp, and applicable for indoor/outdoor lamp belts.
