Description

Waterproof lamp Technical Field The utility model relates to the technical field of lamp strip illumination, in particular to a waterproof lamp. Background In outdoor lighting, bathroom lighting and other scenes, the lamp needs to have good waterproof performance so as to avoid the problems of short circuit, damage and the like caused by water invasion, and the normal use and the service life of the lamp are affected. The existing waterproof lamp mainly has three implementation modes, and in the three implementation modes, the light source adopts forward-mounted LED lamp beads, such as 2216, 2835 or 3838 lamp beads. In a first implementation mode, the body is formed by integrally extruding a lamp strip through silica gel, a silica gel wire is welded at the head end of the body, the body and a wire rod are bonded through die pressing silica gel, the tail end of the body is also bonded through the die pressing silica gel for sealing, in a second implementation mode, the lamp strip welded with the wire is penetrated into a silica gel sleeve, the head end and the tail end of the lamp strip are respectively sealed through glue filling plugs, then the whole silica gel sleeve is filled with silica gel glue from the middle of the body, in a third implementation mode, the lamp strip welded with the wire rod and sleeved with TPU plugs at the two ends is attached to a U-shaped TPU pipe, and then sealing is carried out through PU glue dripping. Through the three implementation modes, the waterproof effect can be realized. But the lamp strip adopting the forward-mounted LED lamp beads is not high in anti-twisting capability, the situation of violent installation of twisted products possibly exists in the implementation process, so that a light source is damaged and cannot be normally lightened, the mechanical strength and the wear resistance of the shell silica gel and PU materials are not high, the situation of collision friction with external sharp objects can exist in the implementation process, so that the lamp strip is scratched and punctured, water vapor enters the lamp strip, the waterproof effect is poor, and the problems of short circuit failure of the lamp strip and burning of a circuit board are caused. Disclosure of utility model The utility model provides a waterproof lamp, which aims to solve the problem of poor waterproof effect caused by low mechanical strength and wear resistance of a shell and materials of the existing waterproof lamp strip. The embodiment of the utility model provides a waterproof lamp, which comprises a lamp body, a sealing assembly and TPU wires, wherein the TPU wires are arranged at one end of the lamp body, the sealing assembly comprises two plugs, the two plugs are respectively wrapped at two ends of the lamp body, one plug is further wrapped on the TPU wires, the lamp body is made of TPU materials, silica gel or plastics through an extrusion process, and the sealing assembly is made of TPU materials through injection molding. Specifically, when the lamp body is formed by adopting silica gel or plastic through an extrusion process, a protective layer is arranged on the lamp body. Specifically, be provided with the protective layer on the lamps and lanterns body, the protective layer adopts the TPU material. Specifically, the waterproof lamp further comprises a light source assembly arranged on the lamp body. Specifically, the light source assembly comprises a lamp bead and a substrate, and electrodes of the lamp bead are flip-chip welded on the substrate. Specifically, the lamp beads are arranged in a plurality and uniformly distributed on the substrate, and the lamp beads are fixed on the substrate by liquid silicone. Specifically, the lamp beads are COF lamp beads or CSP lamp beads. Specifically, the substrate is a flexible printed circuit board. Specifically, the both ends of lamps and lanterns body still are provided with the sealant layer, seal assembly is located the outside of sealant layer. Specifically, the sealant layer is formed by one of glue spraying, glue filling, mould pressing silica gel or injection molding plastic. The embodiment of the utility model provides a waterproof lamp, which comprises a lamp body, a sealing assembly and TPU wires, wherein the TPU wires are arranged at one end of the lamp body, the sealing assembly comprises two plugs, the two plugs are respectively wrapped at two ends of the lamp body, and one plug is further wrapped on the TPU wires. The sealing component is formed by injection molding of TPU materials, and is arranged at two ends of the lamp body, so that the sealing component can seal the two ends of the lamp body, one plug is further wrapped at the joint of the TPU wire and the lamp body, the waterproof effect of the lamp is further improved, and the waterproof lamp can normally emit light.
