Description

Technical Field

[0001] The utility model relates to the technical field of COB flexible light strips, in particular to a COB flexible light strip with a shearable and extensible unit port. Background Technique

[0002] With the rapid development of LED technology, COB (Chip on Board) flexible light strips, as a new type of lighting solution, are gradually occupying an important position in the market. The COB flexible light strip adopts advanced packaging technology to directly integrate multiple LED chips on a flexible circuit board to form an integral light-emitting body. This design not only improves the light efficiency but also significantly reduces the light spot problem, making the lighting effect more uniform and soft. At the same time, the COB flexible light strip has extremely high flexibility and bendability, and can adapt to various complex installation environments and shaping requirements, providing greater flexibility and creative space for lighting design. In addition, the COB flexible light strip also has the advantages of energy conservation, high efficiency, long life, and versatility, and is widely used in multiple fields such as home lighting, commercial lighting, and outdoor lighting.

[0003] Based on the COB flexible light strip, the cuttable COB flexible light strip further meets the user's requirements for flexibility and customization. The length of traditional light strips is usually fixed and cannot be flexibly adjusted according to actual needs. The cuttable COB flexible light strip realizes safe cutting at specific positions through special design and manufacturing processes. Users can freely cut the length of the light strip as needed without worrying about damaging the circuit or affecting the lighting effect. This feature makes the cuttable COB flexible light strip have higher flexibility and applicability in lighting design and can easily handle various complex installation scenarios and shaping requirements. At the same time, the cuttable COB flexible light strip also retains all the advantages of the COB flexible light strip, such as high brightness, uniform lighting, energy conservation, and high efficiency, providing users with a more comprehensive and high-quality lighting solution.

[0004] Patent document CN209196606U discloses a cuttable silicone LED light strip, which includes a silicone sleeve, an LED flexible light strip, a wire, and a flexible light strip control circuit board. The LED flexible light strip is arranged in the silicone sleeve. One end of the wire is electrically connected to the LED flexible light strip, and the other end of the wire is electrically connected to the flexible light strip control circuit board. Several cutting openings are provided at the bottom of the silicone sleeve, and several cutting positions are provided on the surface of the flexible circuit board of the LED flexible light strip. The number of cutting openings is the same as that of the cutting positions and they are aligned one by one. Compared with the prior art, during cutting, only a cutting tool needs to be used to cut at the position of the cutting opening of the utility model, and other positions of the LED flexible light strip will not be damaged, and the operation is convenient.

[0005] In the prior art of the above-mentioned patent, for the aforementioned cuttable COB flexible light strip, although the length can be adjusted according to requirements after each cut, the cutting process is accompanied by a series of potential drawbacks. Specifically, when re-wrapping new insulating material at the cutting position, accidental damage to the light-emitting strips inside the light strip is very likely to occur due to careless operation. This not only affects the overall aesthetics of the light strip, but may also directly cause some lamp beads to fail, reducing the lighting effect. At the same time, during the process of fixing and sealing the cutting position, if the glue or adhesive substance used is not properly handled, it is very likely to penetrate into the inside of the light strip, causing a short circuit between the light-emitting strips, thereby triggering a circuit failure and even causing the entire light strip system to break down. These drawbacks not only increase the maintenance cost and the difficulty of use, but also seriously shorten the service life of the light strip and reduce the user's lighting experience. Therefore, it is particularly important to seek a safer and more efficient cutting and fixing method. Summary of the Invention

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Referring to Figure 1-6 , a COB flexible light strip with a shearable and extensible unit port, includes a light-emitting strip 1 and two silicone encapsulation strips 2. Installation grooves 3 are opened on both of the two silicone encapsulation strips 2. The light-emitting strip 1 is arranged inside the installation grooves 3. The two silicone encapsulation strips 2 and the light-emitting strip 1 are fixedly connected. Extension strips 4 are arranged on both of the two silicone encapsulation strips 2. The two extension strips 4 are bent upward. Cutting notches 5 are opened on both of the two extension strips 4. Sealing blocks 8 are arranged on the two silicone encapsulation strips 2. The sealing blocks 8 are arranged on one side of the extension strips 4. Through grooves 9 are opened on the sealing blocks 8. The two silicone encapsulation strips 2 are slidably connected with the through grooves 9. Fixed sealing components are arranged on the sealing blocks 8. When it is necessary to cut the light strip, pull out the plugging strip 6 between the two extension strips 4, then insert the cutting scissors into the two cutting notches 5, and then perform cutting. After cutting, the two extension strips 4 are flattened in the cutting direction, and the internal light-emitting strip 1 can be wrapped between the two extension strips 4. Then slide the sealing block 8 to move the sealing block 8 to the cutting position. After that, tear off the release layer 13 on one side of the sealing block 8, and then fix the sealing strip 11 on that side to the adhesive tape 12, realizing the use of the sealing strip 11 to block the through groove 9. Then inject glue into the two glue injection holes 10 on the sealing block 8, so that the sealing block 8 can be firmly fixed on the silicone sealing strip. Moreover, the material of the sealing block 8 is the same as that of the silicone sealing strip, which will not affect light transmission and lighting. The above operations realize that after cutting, there is no need to wind the insulating skin, and the cutting part can be directly sealed and fixed through the sealing block 8, ensuring normal light transmission at the cutting part and enhancing its aesthetics at the same time.

[0026] As a preferred technical solution of this embodiment, two blocking tapes 6 are arranged between the two extension strips 4. The blocking tapes 6 and the two extension strips 4 are connected by glue. Pulling protrusions 7 are fixedly installed on both of the two blocking tapes 6. Since the extension strips 4 are bent, there is a certain gap between the two extension strips 4. The gap can be sealed by the blocking tapes 6 to prevent the internal light-emitting strip 1 from being affected. The blocking tapes 6 can be easily torn apart through the pulling protrusions 7.

[0027] As a preferred technical solution of this embodiment, a sealing strip 11 is arranged on one side of the sealing block 8. The sealing strip 11 is arranged above the through groove 9. A sticking tape 12 is arranged on one side of the sealing block 8. A release layer 13 is arranged on the surface of the sticking tape 12. Easy-pull strips 14 are arranged on both sides of the release layer 13. The sealing strip 11 is arranged to block the through groove 9 on the sealing block 8. The sticking tape 12 can block the sealing strip 11. The release layer 13 is arranged to keep the sticking tape 12 with effective adhesiveness when the sticking tape 12 is not in use.

[0028] As a preferred technical solution of this embodiment, injection holes 10 are formed at the top end and the bottom end of the sealing block 8. The injection holes 10 communicate with the through groove 9. By injecting glue through the injection ports, the fixing of the sealing block 8 on the silicone encapsulation tape 2 can be realized.

[0029] As a preferred technical solution of this embodiment, first inclination angles 15 are arranged between the top wall and the bottom wall of the through groove 9 and the horizontal direction. The two first inclination angles 15 are arranged oppositely. The through groove 9 is arranged with a large opening at one end and a small opening at the other end. Since the material of the sealing block 8 is elastic silicone light-transmitting material, it has a certain elasticity itself. After passing two silicone encapsulation tapes 2 through the large opening of the through groove 9, slide the sealing block 8 on the silicone encapsulation tapes 2. The small opening end can press on the silicone encapsulation tapes 2, enhancing the friction force, making the sealing block 8 more compact on the two silicone encapsulation tapes 2, and enhancing the stability of the sealing block 8.

[0030] As a preferred technical solution of this embodiment, a second inclination angle 16 is arranged between the bottom wall of the cutting notch 5 and the horizontal direction. When cutting the upper and lower cutting notches 5 with scissors, there is a certain inclination angle between the two blades of the scissors. The second inclination angle 16 is also arranged at the cutting notch 5, so that the two blades of the scissors can closely fit on the second inclination angle 16, making the contact area between the two blades and the cutting notch 5 larger and facilitating cutting.

[0031] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
