Description

Technical Field

[0001] This utility model relates to the field of flexible LED light strip technology, and in particular to a flexible LED light strip. Background Technology

[0002] Early LED lighting primarily used rigid substrates (such as aluminum substrates), which, while offering high stability, lacked flexibility and could not meet the installation requirements of complex scenarios such as curved surfaces. With the development of flexible electronics technology, flexible substrates based on materials such as polyimide (PI) and silicone have gradually been applied to LED light strips. By integrating LED chips and circuits onto flexible substrates, the bending and folding characteristics of the light strips have been achieved, breaking through the shape limitations of rigid substrates and providing possibilities for lighting decoration on irregular surfaces.

[0003] The applicant discovered through a search that a Chinese patent discloses "A Flexible LED Light Strip" with publication (announcement) number "CN206320573U". This patent mainly uses a pure copper FPC circuit board, which has good electrical and thermal conductivity, fast heat dissipation, and long lifespan. However, this patent does not have a sliding rod and groove matching design. When the initial distance between the two sets of flexible substrates is greater than the length of the docking parts, the distance cannot be shortened by sliding the parts, which makes it difficult for the insert and slot blocks to be nested, directly causing splicing failure. Therefore, we propose a flexible LED light strip. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible LED light strip to solve the problem mentioned in the background art that there is no matching design of sliding rod and sliding groove. When the initial distance between the two sets of flexible substrates is greater than the length of the docking parts, the distance cannot be shortened by sliding the parts, which makes it difficult for the insert block and the slot block to be nested, directly causing the splicing failure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flexible LED light strip, comprising a flexible substrate, a light strip body disposed on the top of the flexible substrate, and connecting components disposed at both ends of the flexible substrate. The connecting components include a fixing block, a connecting block, a slot block, an insert block, and screws. The fixing block is connected to a limiting block via a sliding rod. A sliding groove is provided inside the connecting block, and a limiting groove is provided on the inner wall of the sliding groove.

[0006] As a preferred embodiment, the flexible substrate, the light strip body, the fixing block, the slide bar, the limiting block, the connecting block, the slide groove, and the limiting groove are all provided in two sets. The two sets of fixing blocks are respectively fixedly connected to the corresponding side surface of the two sets of flexible substrates, and the two sets of slide bars are respectively fixedly connected to the corresponding side surface of the two sets of fixing blocks.

[0007] As a preferred embodiment, the two sets of slide rods are slidably connected to the inside of the two sets of slide grooves and the inside of the two sets of limiting grooves, respectively. The slot block is fixedly connected to the outer wall of one set of connecting blocks, and the insert block is fixedly connected to the outer wall of the other set of connecting blocks.

[0008] As a preferred embodiment, the outer wall of the insert block is slidably connected to the inner wall of the slot block, and the screws are threadedly connected to both the inner wall of the slot block and the inner wall of the insert block.

[0009] As a preferred embodiment, the bottom of the flexible substrate is provided with an installation and disassembly assembly, which includes an adhesive strip. Two sets of adhesive strips are provided, and both sets of adhesive strips are fixedly connected to the bottom of the flexible substrate.

[0010] As a preferred embodiment, both sets of adhesive strips have release films on their surfaces, a magnetic block is fixedly connected to the bottom center of the flexible substrate, and a rubber sleeve is fixedly connected to the outer wall of the magnetic block.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. With the set connection components, when the initial distance between the two sets of flexible substrates is greater than the docking length of the insert block and the slot block, the operator can slide the slide bar in the slide groove to push the two sets of connecting blocks to the insertion block of the slot block. This adjustment mechanism can dynamically adjust the connection length, compensate for tolerances or errors, and improve the splicing fault tolerance and adaptability. The insert block and the slot block are nested and fastened with screws to prevent loosening and falling off, and ensure the stable current conduction of the light strip body.

[0013] 2. With the installation and removal components, two sets of adhesive strips are fixed to the bottom of the flexible substrate. Covering with a release film can protect its adhesiveness. When using, the release film can be peeled off to achieve adhesion and fixation to a flat surface. It is suitable for non-magnetic installation bases such as walls and furniture. The magnetic block in the middle of the bottom of the flexible substrate can be directly adsorbed to metal surfaces to meet the installation requirements of magnetic environments. The combination of the two methods makes the flexible LED light strip no longer dependent on a single fixing method and adaptable to more installation scenarios. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see the appendix Figure 1 Appendix Figure 2 and appendix Figure 4 -Appendix Figure 6 A flexible LED light strip includes a flexible substrate 1, a light strip body 2 on the top of the flexible substrate 1, and connecting components 3 at both ends of the flexible substrate 1. The connecting components 3 include a fixing block 301, a connecting block 304, a slot block 307, an insert block 308, and a screw 309. The fixing block 301 is connected to a limiting block 303 via a sliding rod 302. The connecting block 304 has a sliding groove 305 inside, and a limiting groove 306 is formed on the inner wall of the sliding groove 305. The flexible substrate 1, the light strip body 2, the fixing block 301, the sliding rod 302, the limiting block 303, the connecting block 304, the sliding groove 305, and the limiting groove 306 are all provided in two sets. The two sets of fixing blocks 301 are respectively fixedly connected to the corresponding side surfaces of the two sets of flexible substrates 1, and the two sets of sliding rods 302 are respectively fixedly connected to the corresponding side surfaces of the two sets of fixing blocks 301.

[0025] The flexible substrate 1 serves as the basic carrier of the light strip body 2, supporting the LED beads and circuits, while also providing flexibility, allowing it to be bent and folded to adapt to different installation scenarios. The fixing block 301 serves as the basic fixing point of the connecting component 3, and through the cooperation of the sliding rod 302 and the limiting block 303, the connecting component 3 and the flexible substrate 1 are stably connected.

[0026] Two sets of slide rods 302 are slidably connected to the inside of two sets of slide grooves 305 and two sets of limiting grooves 306 respectively. The slot block 307 is fixedly connected to the outer wall of a set of connecting blocks 304. The insert block 308 is fixedly connected to the outer wall of another set of connecting blocks 304. The outer wall of the insert block 308 is slidably connected to the inner wall of the slot block 307. The screws 309 are threadedly connected to the inner walls of the slot block 307 and the inner walls of the insert block 308.

[0027] The slide bar 302, as a sliding connector, is inserted into the slide groove 305 of the connecting block 304, allowing relative sliding between the fixed block 301 and the connecting block 304 to achieve telescopic adjustment. The limiting block 303 cooperates with the limiting groove 306 to prevent the connecting block 304 from sliding out.

[0028] Specifically, through the connection component 3, when the initial distance between the two sets of flexible substrates 1 is greater than the docking length of the insert block 308 and the slot block 307, the operator can slide the slide bar 302 within the slide groove 305 to push the two sets of connection blocks 304 until the insert block 308 is inserted into the slot block 307. This adjustment mechanism can dynamically adjust the connection length, compensate for tolerances or errors, and improve the splicing fault tolerance and adaptability. The insert block 308 and the slot block 307 are nested and secured with screws 309 to prevent loosening or falling off, ensuring stable current conduction in the light strip body 2.

[0029] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 7 and appendix Figure 8 The bottom of the flexible substrate 1 is provided with an installation and disassembly assembly 4. The installation and disassembly assembly 4 includes an adhesive strip 401. Two sets of adhesive strips 401 are provided. Both sets of adhesive strips 401 are fixedly connected to the bottom of the flexible substrate 1. Release film 402 is provided on the surface of both sets of adhesive strips 401. A magnetic block 403 is fixedly connected to the middle of the bottom of the flexible substrate 1. A rubber sleeve 404 is fixedly connected to the outer wall of the magnetic block 403.

[0030] Release film 402 can protect the adhesiveness of adhesive strip 401. Release film 402 covers the surface of adhesive strip 401 and can isolate dust, moisture and other impurities when not in use, preventing the adhesive strip 401 from failing prematurely. When in use, simply peel off release film 402 to expose the adhesive side of adhesive strip 401 for easy and quick installation.

[0031] Specifically, through the installation and disassembly component 4, two sets of adhesive strips 401 are fixed to the bottom of the flexible substrate 1. The release film 402 covers them to protect their adhesiveness. When in use, the release film 402 can be peeled off to achieve adhesion and fixation to a flat surface. It is suitable for non-magnetic installation bases such as walls and furniture. The magnetic block 403 in the middle of the bottom of the flexible substrate 1 can be directly adsorbed to the metal surface to meet the installation requirements of magnetic environments. The combination of the two methods makes the flexible LED light strip not dependent on a single fixing method and adaptable to more installation scenarios.

[0032] Working principle of this utility model: This utility model is a flexible LED light strip. First, the operator removes the release film 402 from the surface of the two sets of adhesive strips 401 at the bottom of the flexible substrate 1, exposing the adhesive surface. The fixing method is selected according to the installation scenario. If it is a non-magnetic surface such as a wall or furniture, the flexible substrate 1 is fixed by adhering it with the adhesive strips 401. If it is a metal surface, the magnetic attraction block 403 at the bottom is used to attract it to the mounting surface. The rubber sleeve 404 on the outer wall of the magnetic attraction block 403 can reduce scratches on the mounting surface. When it is necessary to connect two sets of flexible substrates 1, the operator first aligns the connecting components 3 of the two light strips facing each other, pushes the two connecting blocks 304, and makes the sliding rod 302 slide along the sliding groove 305. The limiting block 30... 3. As the slide bar 302 moves, it will slide synchronously inside the limiting groove 306, continuously pushing the connecting block 304 until the insert block 308 on one set of connecting blocks 304 is fully inserted into the slot block 307 of the other set of connecting blocks 304. At this time, the screw 309 passes through the threaded hole of the slot block 307 and the insert block 308 and is tightened to complete the mechanical fixation. After the splicing is completed, the flexible substrate 1 adapts to the bending and folding requirements of the mounting surface with its own flexible characteristics, supports the light strip body 2 to emit light stably, and the connecting component 3 compensates for the spacing deviation through the adjustment of the slide bar 302. With the tightening of the insert block 308, the slot block 307 and the screw 309, the connection of the two sets of flexible substrates 1 is stable and the current conduction is continuously stable.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
