Description

Technical Field

[0001] This utility model belongs to the field of decorative lighting technology, specifically relating to a seamless splicing structure for neon lights. Background Technology

[0002] Neon light strips are flexible lighting products used for decoration or illumination. They combine the visual effects of traditional neon lights with the advantages of modern LED technology. They emit light through a series of LED beads and achieve uniform light transmission with silicone or PVC sleeves. They can be designed as single color, multi-color mixed light, or dynamic effects. The ends of the light strip are glued with sealing plugs to seal the light strip ports, making them waterproof and dustproof. One end of the plug is also designed with a wire outlet hole to support the passage of power cords or signal cables, adapting to different wiring needs.

[0003] In existing technologies, because the ends of the light strips are fitted with plugs, the thickness of the joint increases when two light strips are joined together. Furthermore, the application of adhesive can easily cause light scattering or uneven light transmission of the adhesive layer, all of which can lead to dark areas at the joint of the light strips, creating a sense of light breakage and affecting the aesthetics of the light strips. Utility Model Content

[0004] The purpose of this invention is to provide a seamless splicing structure for neon lights, which combines the traditional double end caps into an integrated groove, reducing the interference of glue on light refraction, improving light continuity, and the transparent plate not only reduces the joint thickness, but also has light transmission and uniformity, preventing dark areas from appearing at the splicing point of the light strips, and improving the splicing effect and aesthetics of the light strips.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A seamless splicing structure for neon lights includes a clamping groove at the splicing point of two light strips. A transparent plate is fixedly connected to the middle of the inner wall of the clamping groove. The light strips are located on both sides of the transparent plate. The side walls of the transparent plate are provided with outwardly radiating light guide grooves, the density and size of which increase along the direction away from the light source. Pre-set holes are symmetrically opened on the two side walls of the clamping groove. The outer side wall of the light strip is provided with protrusions that engage and match the pre-set holes.

[0007] The inner wall of the groove is symmetrically provided with sealing strips, and the outer wall of the light strip is correspondingly provided with a sealing groove that is interference fit with the sealing strip.

[0008] The clamping groove has symmetrically opened cable outlets on the sidewalls adjacent to the pre-set hole. The cable outlets are distributed on both sides of the transparent plate and are connected to the cable channel of the light strip.

[0009] The opening end of the clamping groove is movably engaged with a transparent sealing plate through symmetrically opened slots, and a protruding plate is symmetrically fixedly connected to the inner wall of one of the slots.

[0010] One end of the transparent sealing plate is fixedly connected to an elastic end, and both ends of the plate are symmetrically provided with grooves for movably engaging with the convex plate. One side of each groove is provided with a through groove.

[0011] The technical effects achieved by this utility model are as follows: the traditional double end caps are combined into an integrated groove, which reduces the interference of glue on light refraction and improves the continuity of light. In addition, the transparent plate not only reduces the thickness of the joint, but also has light transmission and light uniformity, preventing dark areas from appearing at the splicing of the light strips and improving the splicing effect and aesthetics of the light strips.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0019] like Figures 1-4As shown, a seamless splicing structure for neon lights includes a groove 101 located at the splicing point of two light strips 1. A transparent plate 102 is fixedly connected to the middle of the inner wall of the groove 101. The light strips 1 are located on both sides of the transparent plate 102. The side wall of the transparent plate 102 is provided with outwardly radiating light guide grooves 103, the density and size of which increase along the direction away from the light source. Pre-set holes 108 are symmetrically opened on the two side walls of the groove 101. The outer side wall of the light strip 1 is provided with protrusions 104 that engage and match the pre-set holes 108. Sealing strips 107 are symmetrically provided on the inner wall of the groove 101. Sealing grooves 105 that are interference-fitted with the sealing strips 107 are correspondingly opened on the outer side wall of the light strip 1.

[0020] The clamping groove 101 has symmetrically opened outlet pipes 106 on the side wall adjacent to the pre-set hole 108. The outlet pipes 106 are distributed on both sides of the transparent plate 102 and are connected to the wiring channel of the light strip 1. The open end of the clamping groove 101 is movably engaged with the transparent sealing plate 109 through the symmetrically opened slots 110. The inner wall of one of the slots 110 is symmetrically fixedly connected with the protrusion 111. One end of the transparent sealing plate 109 is fixedly connected with the elastic end 114, and both ends of it are symmetrically opened with grooves 112 for movably engaging with the protrusion 111. One side of each groove 112 is opened with a through groove 113.

[0021] According to the above structure, the cable of the light strip 1 is passed through the outlet tube 106, and the two light strips 1 are respectively embedded into the clamping groove 101 facing each other, so that the sealing strip 107 is fitted with the sealing groove 105 for waterproofing, the protruding post 104 is fitted with the pre-set hole 108 for fixing, and the transparent plate 102 is located between the two light strips 1. The clamping groove 101 can be made of materials such as liquid silicone, thermoplastic polyurethane, etc., preferably thermoplastic polyurethane. The protruding post 104 can be made of materials such as polyoxymethylene, ABS plastic, silicone, glass fiber reinforced nylon, etc., preferably glass fiber reinforced nylon. The transparent plate 102 and the transparent sealing plate 109 can be made of materials such as acrylic, transparent PC, etc., preferably transparent PC.

[0022] Furthermore, when the light strip 1 emits light, the transparent plate 102 has good light transmittance and its thickness is much smaller than that of the traditional double-end joint. The light guide grooves 103 are densely arranged and have a small diameter near the light source to reduce light loss, and are sparsely arranged and have a larger diameter away from the light source to enhance the light scattering intensity, avoid local over-brightness, and make the light more uniform.

[0023] Furthermore, when the transparent cover plate 109 is inserted into the slot 110, the elastic end 114 at one end is squeezed by the protruding plate 111, and the end of the groove 112 is tilted so that the rectangular opening of the through slot 113 becomes a triangle, so that the groove 112 can engage with the protruding plate 111. After engaging, the end of the groove 112 elastically returns to its original position. The elastic end 114 is made of, but is not limited to, nylon, polypropylene, polycarbonate, etc., preferably polycarbonate. The transparent cover plate 109 is located on one side of the splicing point of the two light strips 1 to cover the gap at the joint and prevent water droplets and impurities from entering. At the same time, it has an auxiliary fixing effect on the light strip 1. The transparent cover plate 109 also has high light transmittance and will not affect the light effect of the light strip 1.

[0024] This utility model combines the traditional double end caps into an integrated clamping groove 101, reducing the interference of glue on light refraction and improving light continuity. In addition, the transparent plate 102 not only reduces the joint thickness, but also has light transmission and light uniformity, preventing dark areas from appearing at the splicing point of the light strip 1, and improving the splicing effect and aesthetics of the light strip 1.

[0025] The working principle of this utility model is as follows: the cable of the light strip 1 is passed through the outlet tube 106, and the two light strips 1 are respectively embedded into the clamping groove 101 facing each other, so that the sealing strip 107 is fitted with the sealing groove 105 for waterproofing, the protruding post 104 is fitted with the pre-set hole 108 for fixing, and the transparent plate 102 is located between the two light strips 1. The clamping groove 101 can be made of materials such as liquid silicone, thermoplastic polyurethane, etc., preferably thermoplastic polyurethane. The protruding post 104 can be made of materials such as polyoxymethylene, ABS plastic, silicone, glass fiber reinforced nylon, etc., preferably glass fiber reinforced nylon. The transparent plate 102 and the transparent sealing plate 109 can be made of materials such as acrylic, transparent PC, etc., preferably transparent PC.

[0026] Furthermore, when the light strip 1 emits light, the transparent plate 102 has good light transmittance and its thickness is much smaller than that of the traditional double-end joint. The light guide grooves 103 are densely arranged and have a small diameter near the light source to reduce light loss, and are sparsely arranged and have a larger diameter away from the light source to enhance the light scattering intensity, avoid local over-brightness, and make the light more uniform.

[0027] Furthermore, when the transparent cover plate 109 is inserted into the slot 110, the elastic end 114 at one end is squeezed by the protrusion 111, and the end of the groove 112 is tilted so that the rectangular opening of the through slot 113 becomes a triangle, so that the groove 112 can engage with the protrusion 111. After engaging, one end of the groove 112 elastically returns to its original position. The elastic end 114 is made of, but is not limited to, nylon, polypropylene, polycarbonate, etc., preferably polycarbonate. The transparent cover plate 109 is located on one side of the splicing point of the two light strips 1 to cover the gap at the joint and prevent water droplets and impurities from entering. At the same time, it has an auxiliary fixing effect on the light strip 1. The transparent cover plate 109 also has high light transmittance and will not affect the light effect of the light strip 1.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
