Description

Technical Field

[0001] This application relates to the technical field of light strips, and in particular to a low-light-loss, uniform-light light strip. Background Technology

[0002] LED strip lights are devices that emit continuous light, typically composed of multiple LED lights. They can be bent or cut to fit various installation environments and scenarios. LED strip lights are commonly used for decoration, lighting, or indication purposes, and are widely used due to their flexibility and ease of installation.

[0003] Reference Figure 8 In the prior art, the light strip includes a protective strip 1 and a lamp core 2. The protective strip 1 has a protective channel 13. The lamp core 2 includes a flexible circuit strip 21 and a lamp body 22. The flexible circuit strip 21 is installed on the side wall of the protective channel 13, and the lamp body 22 is disposed on the flexible circuit strip 21. The protective channel 13 is filled with a light-guiding adhesive layer. The light emitted by the lamp body 22 passes through the light-guiding adhesive layer and is continuously reflected by the inner wall of the protective channel 13, thereby presenting the effect of connecting light outward to achieve a uniform light effect.

[0004] However, in this type of light strip, the light emitted by the lamp body is reflected by the inner wall of the protective channel to achieve a uniform light effect. This process results in significant light loss, increases the overall energy consumption of the light strip, and is not conducive to energy conservation and environmental protection. Therefore, further improvements are needed. Utility Model Content

[0005] In order to achieve uniform light distribution and reduce light loss, this application provides a low-light-loss uniform light strip.

[0006] The low-light-loss, uniform-light LED strip provided in this application adopts the following technical solution:

[0007] A low-light-loss uniform light strip includes a protective strip and a lamp core. The protective strip includes a connecting part and two protective parts, which are arranged at intervals along the width direction of the connecting part, forming a protective channel between the connecting part and the two protective parts. The lamp core is disposed on the surface of the connecting part near the protective channel, and a first uniform light layer is filled in the protective channel, which wraps around the lamp core.

[0008] By adopting the above technical solution, the lamp core is placed on the surface of the connecting part near the protective channel, so that the light emitted by the lamp core is directly directed towards the opening of the protective channel, thereby reducing light loss and reducing the overall energy consumption of the light strip. The first light-diffusing layer is wrapped around the lamp core, so that when the light passes through the first light-diffusing layer, the first light-diffusing layer can effectively transmit and disperse the light, thereby presenting the effect of connecting the light outward, so as to achieve the effect of light uniformity.

[0009] Optionally, the first light-diffusing layer has a first protrusion on the sidewall near the protective part, and the surface of the protective part near the protective channel has a first groove for the first protrusion to be fitted into; the surface of the protective part near the protective channel has a second protrusion, and the sidewall of the first light-diffusing layer near the protective part has a second groove for the second protrusion to be fitted into.

[0010] By adopting the above technical solution, the matching and embedding of the first protrusion and the first groove, and the second protrusion and the second groove, improves the connection between the first light-diffusing layer and the protective strip.

[0011] Optionally, the lamp core includes a flexible circuit strip and a lamp body. The flexible circuit strip is disposed on the surface of the connecting part, and both ends of the flexible circuit strip extend along the length direction of the protective strip. The lamp body is disposed on the flexible circuit strip and multiple flexible circuit strips are spaced apart along the length direction of the flexible circuit strip. The surface of the lamp body is provided with a second light-diffusing layer.

[0012] By adopting the above technical solution, the light emitted by the lamp body passes through the second light-diffusing layer and the first light-diffusing layer in sequence, thereby forming two paths of light dispersion and improving the light-diffusing effect.

[0013] Optionally, two lamp cores are arranged side by side along the width of the protective strip, with the lamp bodies of the two lamp cores arranged in an alternating pattern.

[0014] By adopting the above technical solution, the multiple lamp bodies of the two lamp cores are arranged in an alternating manner, which improves the uniform light effect.

[0015] Optionally, an intersection area is formed between the two lamp cores, and the flexible circuit strips of the two lamp cores gradually move away from the connection part from the side closer to the intersection area to the side farther away from the intersection area.

[0016] By adopting the above technical solution, the flexible circuit strips of the two lamp cores gradually move away from the connection part from the side closer to the intersection area to the side farther away from the intersection area, so that the light emitted by the two lamp cores converges towards the intersection area. Combined with the staggered arrangement between the lamp bodies of the two lamp cores, the light uniformity effect is further improved.

[0017] Optionally, the included angle between the surfaces of the two flexible circuit strips of the lamp cores away from the connection portion is between 150° and 160°.

[0018] By adopting the above technical solution, the angle between the surfaces of the flexible circuit strips of the two lamp cores away from the connection part is set between 150° and 160° to ensure that the light emitted by the two lamp cores can converge and guarantee uniform light. At the same time, it maintains the light strip's good bending performance as much as possible, avoiding the possibility that the bending performance of the light strip would be greatly reduced due to an excessively large angle between the circuit strip and the connection part.

[0019] Optionally, the protective channel is provided with a shaping strip, and the surface of the shaping strip away from the connecting part is provided with a shaping groove; the shaping groove includes a deformation part and an overlapping part, the surface of the flexible circuit strip near the connecting part is provided with a deformation strip, the deformation strip is embedded in the deformation part, and the side of the flexible circuit strip near the intersection area overlaps in the overlapping part.

[0020] By adopting the above technical solution, when the light strip is bent, the deformation strip deforms within the deformation section, and the deformation section provides sufficient deformation space for the deformation strip, thereby improving the bending effect of the light strip.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By placing the lamp core on the surface of the connecting part close to the protective channel, the light emitted by the lamp core is directed directly towards the opening of the protective channel, thereby reducing light loss and thus reducing the overall energy consumption of the light strip. The first light-diffusing layer is wrapped around the lamp core, so that when light passes through the first light-diffusing layer, the first light-diffusing layer can effectively transmit and disperse the light, thereby presenting a connecting light effect to the outside, so as to achieve the effect of light uniformity;

[0023] 2. By tilting the two lamp cores, the flexible circuit strips of the two lamp cores gradually move away from the connection part from the side closer to the intersection area to the side farther away from the intersection area, so that the light emitted by the two lamp cores converges towards the intersection area. Combined with the staggered arrangement between the lamp bodies of the two lamp cores, the light uniformity effect is further improved.

[0024] 3. By setting the deformation strip, when the light strip is bent, the deformation strip deforms within the deformation section. The deformation section provides sufficient deformation space for the deformation strip, improving the bending effect of the light strip. Attached Figure Description

[0034] The following combination Figures 1-7 This application will be described in further detail.

[0035] Example 1: This application discloses a low-light-loss uniform light strip.

[0036] Reference Figure 1 , Figure 2 A low-light-loss uniform light strip includes a protective strip 1 and a lamp core 2. The protective strip 1 includes a connecting part 11 and two protective parts 12. The two protective parts 12 are fixedly installed on the surface of the connecting part 11 and are arranged at intervals along the width direction of the connecting part 11. Both ends of each protective part 12 extend along the length direction of the connecting part 11. The connecting part 11 and the two protective parts 12 are integrally formed, and a protective channel 13 is formed between the connecting part 11 and the two protective parts 12.

[0037] The lamp wick 2 is installed inside the protective channel 13. In this embodiment, the lamp wick 2 includes a flexible circuit strip 21 and a lamp body 22. The flexible circuit strip 21 is fixedly installed on the surface of the connecting part 11 near the protective channel 13. The flexible circuit strip 21 and the connecting part 11 can be fixedly connected by adhesive. The flexible circuit strip 21 is long and strip-shaped, and both ends of the flexible circuit strip 21 extend along the length direction of the protective strip 1. The lamp body 22 is fixedly installed on the surface of the flexible circuit strip 21 away from the connecting part 11, and multiple lamp bodies 22 are spaced apart along the length direction of the flexible circuit strip 21.

[0038] Each lamp body 22 has a second light-diffusing layer 4 installed on its surface, and the protective channel 13 is filled with a first light-diffusing layer 3, which wraps around the lamp core 2. In this embodiment, the first light-diffusing layer 3 and the second light-diffusing layer 4 are both made of transparent materials, such as PC, silicone, PVC, ABS, PS, etc.

[0039] Reference Figure 2 In this embodiment, the first light-diffusing layer 3 has a first protrusion 31 integrally formed on the side wall near the protective part 12, and the protective part 12 has a first groove 121 formed on the surface near the protective channel 13. The shape of the first groove 121 is adapted to the shape of the first protrusion 31 so that the first protrusion 31 can be fitted into it. The protective part 12 has a second protrusion 122 integrally formed on the surface near the protective channel 13. The second protrusion 122 is located on the side of the first groove 121 away from the connecting part 11. The first light-diffusing layer 3 has a second groove 32 formed on the side wall near the protective part 12. The shape of the second groove 32 is adapted to the shape of the second protrusion 122 so that the second protrusion 122 can be fitted into it.

[0040] The second protrusion 122 forms a first inclined surface 123 near the side wall of the protective channel 13. The first inclined surface 123 gradually slopes inward from the side near the connecting part 11 to the side away from the connecting part 11 into the protective channel 13.

[0041] It should be noted that, in this embodiment, when the first light-diffusing layer 3 is made, the liquid light-diffusing material is filled into the protective channel 13. It can be naturally placed to solidify and form the first light-diffusing layer 3, and naturally form the first protrusion 31 and the second groove 32.

[0042] The implementation principle of Embodiment 1 of this application is as follows: by placing the lamp core 2 on the surface of the connecting part 11 near the protective channel 13, the light emitted by the lamp core 2 is directly directed towards the opening of the protective channel 13, thereby reducing light loss and thus reducing the overall energy consumption of the light strip. With the first light-diffusing layer 3 and the second light-diffusing layer 4, the light emitted by the lamp body 22 passes sequentially through the second light-diffusing layer 4 and the first light-diffusing layer 3. The first light-diffusing layer 3 and the second light-diffusing layer 4 can effectively transmit and disperse light, thereby presenting a connected light effect and improving the light-diffusing effect.

[0043] A first groove 121 and a second protrusion 122 are provided in the protective part 12 to improve the connection between the first light-diffusing layer 3 and the protective strip 1.

[0044] Example 2: This application discloses a low-light-loss uniform light strip.

[0045] The difference between the low light loss uniform light strip disclosed in this application and Embodiment 1 is that:

[0046] Reference Figure 3 , Figure 4In this embodiment, a shaping strip 5 is installed inside the protective channel 13. The shaping strip 5 is made of flexible PVC plastic and is installed inside the protective channel 13 by adhesive bonding. A shaping groove 51 is provided on the surface of the shaping strip 5 away from the connecting part 11. There are two shaping grooves 51 and they are arranged at intervals along the width direction of the connecting part 11. Both ends of each shaping groove 51 extend along the length direction of the connecting part 11.

[0047] There are two lamp wicks 2. The structure of the lamp wick 2 in this embodiment is the same as that in embodiment 1, and will not be described again here (that is, each lamp wick 2 includes a flexible circuit strip 21 and multiple lamp bodies 22). The multiple lamp bodies 22 of the two lamp wicks 2 are arranged in an alternating manner. The two lamp wicks 2 are correspondingly provided with two shaping grooves 51. The flexible circuit strip 21 of each lamp wick 2 is embedded in the corresponding shaping groove 51. The flexible circuit strip 21 of the lamp wick 2 is fixedly connected to the inner wall of the shaping groove 51 by adhesive bonding.

[0048] Reference Figure 3 , Figure 5 It should be noted that in this embodiment, the first protrusion 31 is disposed on the side wall of the shaping strip 5, and the first protrusion 31 and the shaping strip 5 are integrally formed. The side wall of the shaping strip 5 near the protective part 12 has a second inclined surface 52, which abuts against the first inclined surface 123 of the second protrusion 122. The side wall of the shaping strip 5 near the protective part 12 has a plurality of notches 53 for the first light-diffusing layer 3 to be inserted. The plurality of notches 53 are arranged at intervals along the length direction of the shaping strip 5. One end of the notch 53 penetrates the surface of the shaping strip 5 near the connecting part 11, and the other end penetrates the surface of the shaping strip 5 away from the connecting part 11. With this design, when the first light-diffusing layer 3 is filled, some light-diffusing material can flow into the notch 53. After the light-diffusing material is cured, the connection stability between the first light-diffusing layer 3 and the shaping strip 5 is enhanced.

[0049] The notch 53 has a third inclined surface 531, which gradually slopes from the side closer to the connecting part 11 toward the side farther away from the connecting part 11 and toward the side farther away from the protective part 12.

[0050] The implementation principle of Embodiment 2 of this application is as follows: When connecting the lamp wick 2 and the protective strip 1, the lamp wick 2 is pre-connected to the shaping strip 5. Then, adhesive is applied to the outer wall of the shaping strip 5, and the shaping strip 5 is embedded into the protective channel 13 by extrusion to achieve the installation of the lamp wick 2. Then, a light-diffusing material is filled into the protective channel 13. After the light-diffusing material cures, it forms a first light-diffusing layer 3. The notch 53 enhances the connection between the first light-diffusing layer 3 and the shaping strip 5. The combination of the shaping strip 5 and the first light-diffusing layer 3 forms a "full enclosure" of the lamp wick 2, improving the protective effect of the lamp wick 2. By setting two lamp wicks 2, and the multiple lamp bodies 22 of the two lamp wicks 2 are arranged in an alternating manner, the light-diffusing effect is further improved.

[0051] Example 3: This application discloses a low-light-loss uniform light strip.

[0052] The difference between the low light loss uniform light strip disclosed in this application embodiment and Embodiment 2 is that:

[0053] Reference Figure 6 In this embodiment, for ease of description, the area between the two lamp cores 2 is defined as the intersection area 14. The flexible circuit strips 21 of the two lamp cores 2 gradually move away from the connecting part 11 from the side closer to the intersection area 14 to the side farther away from the intersection area 14. The included angle between the surfaces of the flexible circuit strips 21 of the two lamp cores 2 away from the connecting part 11 is between 150° and 160°. Specifically, in this embodiment, the included angle between the surfaces of the flexible circuit strips 21 of the two lamp cores 2 away from the connecting part 11 is 155°.

[0054] The implementation principle of Embodiment 3 of this application is as follows: the flexible circuit strips 21 of the two lamp cores 2 gradually move away from the connecting part 11 from the side close to the intersection area 14 to the side away from the intersection area 14, so that the light emitted by the two lamp cores 2 converges towards the intersection area 14. Combined with the staggered arrangement between the lamp bodies 22 of the two lamp cores 2, the light uniformity effect is further improved.

[0055] Example 4: This application discloses a low-light-loss uniform light strip.

[0056] The difference between the low light loss uniform light strip disclosed in this application embodiment and Embodiment 3 is that:

[0057] Reference Figure 7In this embodiment, each shaping groove 51 includes a deformable part 511 and an overlapping part 512. A deformable strip 23 is fixedly installed on the surface of the flexible circuit strip 21 near the connecting part 11. The deformable strip 23 is made of elastic material such as rubber strip. The deformable strip 23 is embedded in the deformable part 511, and the side wall of the deformable strip 23 away from the flexible circuit strip 21 abuts against the inner side wall of the deformable part 511 near the connecting part 11. The deformable strip 23 and the flexible circuit strip 21, and the deformable strip 23 and the inner side wall of the deformable part 511 near the connecting part 11 are fixedly connected by adhesive. The side of the flexible circuit strip 21 near the intersection area 14 overlaps in the overlapping part 512.

[0058] The implementation principle of Embodiment 4 of this application is as follows: By setting the deformation strip 23, on the one hand, it supports the lamp core 2, keeping the flexible circuit strip 21 of the lamp core 2 in an inclined state; on the other hand, the deformation strip 23 can enhance the bending ability of the light strip to a certain extent. When the light strip is bent, the deformation strip 23 deforms in the deformation part 511. The deformation part 511 provides sufficient deformation space for the deformation strip 23, thereby improving the bending effect of the light strip.

[0059] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
