Description

Technical Field

[0001] The invention relates to the technical field of LED light strips, in particular to an LED light strip with a flexible substrate. Background Art

[0002] LED light strip is a lighting device that assembles multiple light-emitting diodes (LEDs) on a strip-shaped flexible circuit board or a hard board. It usually has a slender shape, and the length can be cut or spliced ​​according to actual needs. From the internal structure, LED lamp beads are the core components, which are closely arranged on the circuit board. These lamp beads are small in size and can achieve high brightness. Its luminous colors are diverse, including common white, warm white, red, green, blue, etc., and can also be controlled to achieve a variety of color changes, such as gradient, flashing and other effects, which makes it widely used in the field of decoration. For example, it can be used to outline the outline of buildings, decorate indoor ceilings and cabinets, etc. It can also be used for the decoration of car interiors. It also plays an important role in the layout of some stage scenes and the production of advertising signs;

[0003] The Chinese patent with the announcement number "CN221172147U" discloses an LED light strip with a flexible substrate, including an insert block, a docking block, a connection groove, a connection block, a flip block, a fixing block, a rotating shaft, a sliding rod and a push block. The above device can not only realize the connection of two LED light strips to achieve the purpose of extending the length of the light strip, but also after the insert block is inserted into the connection groove to complete the connection of the light strip, the fixing block can be inserted into the corresponding fixing groove to fix the two connected LED light strips to prevent them from falling off, thereby improving the stability after connection, replacing the previous method of connecting the light strip with tape;

[0004] Although the above-mentioned device as a whole can realize the quick connection of the combined light strip and has certain convenience, it has obvious deficiencies in the specific use process. First, the device lacks a protective structure for the entire light strip. Since it connects multiple light strips in series through the connecting structure in the middle, during long-term use, whether the light strip itself is damaged or seepage occurs at the connection, it is very likely to cause water to enter the entire light strip, and then cause a short circuit. Once a short circuit occurs, the entire light strip composed of multiple series is very likely to be burned, which will cause great economic losses. Moreover, a large-scale short circuit may also cause a large-scale fire. The overall use is relatively risky. Secondly, the device uses a torsion spring for limiting. When disassembly and assembly is required, the two push blocks must be pushed to move synchronously at the same time to achieve it. This obviously makes the overall disassembly and assembly process more inconvenient and cannot be quickly disassembled and assembled. In summary, the device has many problems during use and needs to be improved. Summary of the invention

[0020] Thirdly, in the present invention, the insurance mechanism in the present invention plays a vital role in the operation of the device.

[0038] The working principle of the present invention is as follows: by setting the connecting device 2, the device can be rotated by twisting the adjusting handle 225 during actual use, thereby driving the linkage plate 223 to push the guide plate 224, causing the telescopic spring 2321 to be in an extended state. At this time, the plug 3 is inserted into the inner side of the slot 24. When the plug 3 and the slot 24 are plugged into each other, the limiting telescopic spring 2321 can be reset and drive the slider 2323 to move inward. During the inward movement of the slider 2323, the limiting frame 2324 can be driven to move. At this time, the limiting frame 2324 will pass through the limiting groove 2322 at the shell 21 and be inserted into the inner side of the limiting groove 2322 of the plug 3. In this way, the plug 3 can be assisted in being clamped and installed on both sides of the shell 21, so that the combined flexible light strip 1 can be quickly installed, which is convenient for combining and installing multiple sets of flexible light strips. The light strip 1 provides great convenience, and during use, if the flexible light strip 1 needs to be disassembled, the linkage plate 223 can be driven to push the guide plate 224 outward by twisting the adjustment handle 225. It is worth noting that the overall shape of the linkage plate 223 is a narrow and long elliptical setting. When the linkage plate 223 rotates, the guide plate 224 can be squeezed to move outward, and the outward movement of the guide plate 224 can drive the connecting rod 222 to pull the limit frame 2324 outward. At this time, the telescopic spring 2321 is in an extended state, and the outward movement of the limit frame 2324 will cause the inner end of the limit frame 2324 to break away from the inside of the limit groove 2322. At this time, the flexible light strip 1 can be removed from both sides of the connecting device 2. In summary, the device as a whole can quickly assemble or separate the flexible light strip 1 during use, which greatly improves the convenience of using the device as a whole.

[0039] By setting the safety mechanism 25, the device can be used to insert the fuse 254 into the inner side of the installation groove 251. At this time, the conductive spring 2561 in the side slide groove 2562 is reset, which can prompt the conductive spring 2561 to push the conductive copper plate 2563 inside the side slide groove 2562 to move outward. After the conductive copper plate 2563 moves outward, it can fit on both sides of the fuse 254. Then, the flip cover 257 is rotated to cover the outer side of the installation groove 251. At this time, the retractable spring 2321 is reset. The slider 2323 drives the limiting protrusion 2523 on the limiting rod 2521 to be inserted into the limiting hole 2524 of the limiting plate 2522, so as to assist in covering the sealing installation groove 251. In this case, the circuits among the fuse 254, the conductive copper plate 2563, the conductive spring 2561 and the conductive seat 4 are connected, so that the power supply can be automatically connected after the flexible light strip 1 is installed, and no additional circuit wires or connectors are required to connect the power supply. This not only improves the convenience of use, but also its fitting contact design can facilitate disassembly and assembly for flexible application. When a short circuit occurs, the fuse 254 can be blown first. After the fuse 254 is blown, the power supply at each flexible light strip 1 can be quickly cut off. After the power supply at each flexible light strip 1 is cut off, each flexible light strip 1 can be protected, which can effectively avoid the situation where the entire flexible light strip 1 is melted due to a short circuit. Moreover, if the fuse 254 needs to be replaced during use, the adjustment handle 225 can be turned to drive the linkage. The plate 223 pushes the guide plate 224 to move outward, and the outward movement of the guide plate 224 can synchronously pull the limit frame 2324 to drive the limit rod 2521 on the slider 2323 to move outward, and the limit protrusion 2523 on the limit rod 2521 can be separated from the inside of the limit hole 2524. At this time, the limit plate 2522 loses its limit and the flip cover 257 can be rotated to open the installation slot 251, so as to facilitate the disassembly and removal of the fuse 254. In summary, the device as a whole can quickly replace the fuse 254, which provides great convenience for the use of the device.
