LED lamp strip convenient to install and fix

Abstract

This invention discloses an LED light strip that is easy to install and fix, relating to the field of LED light strip installation technology. Addressing the problem of poor installation performance of existing LED light strips on irregular surfaces, the following solution is proposed: The installation surface has two symmetrical fixing frames on its exterior, and each fixing frame has a connecting plate on its exterior. This invention's easy-to-install LED light strip, through the use of corrugated elastic plates, perforated soft pads, and curved panels, avoids unevenness caused by pits, sand particles, raised seams, and corners on the wall or panel surface. This prevents the light strip from bending, delaminating, warping, or arching due to wall surface irregularities, deflections, and other defects. It also reduces the occurrence of a wavy light-emitting surface, resulting in bright and dark stripes when illuminating adjacent walls, and the light strip being partially suspended or subjected to pressure, leading to fatigue fracture of internal solder joints. This allows for rapid deployment of the light strip.

Description

Technical Field

[0001] This invention relates to the field of LED light strip technology, and in particular to an LED light strip that is easy to install and fix. Background Technology

[0002] LED light strips are light-emitting diodes assembled on a strip-shaped flexible circuit board or rigid PCB board. They are named for their strip-like shape. Because of their typical lifespan of 80,000 to 100,000 hours, they are a very energy-efficient and environmentally friendly new type of lighting and are gradually emerging in various decoration industries. Light strip is short for LED light strip.

[0003] LED light strips are often installed on walls, ceilings, or cabinet surfaces in interior decoration. In actual construction, walls and panels often have unevenness defects such as pits, sand particles, and raised seams. If the light strip is directly pasted onto such surfaces, it will bend with the undulations of the wall, resulting in poor installation. Especially in corner areas, the adhesive backing method cannot guarantee an effective connection between the light strip and the installation surface, causing issues such as delamination, warping, and arching. This results in a wavy light-emitting surface, creating bright and dark stripes when illuminating adjacent walls, leading to a poor visual appearance. Summary of the Invention

A fitting groove is provided on the stepped groove, and the inner wall of the fitting groove is slidably connected to the exterior of the carbon fiber wire. The two ends of the main wire are fixedly connected to both sides of the movable rod, and each of the multiple trapezoidal sliders has symmetrical through holes. The inner wall of each through hole has multiple circumferentially distributed grooves. The same constraint frame is slidably connected in the multiple grooves on the same side. A rubber pad is fixedly connected to the side of the constraint frame near the light strip body, and the rubber pad is in contact with the opposite side of the outer side of the light strip body. Neodymium magnets are set in the multiple constraint frames, and the neodymium magnets are fixedly connected to the opposite side of the rubber pads. Multiple symmetrical protrusions are fixedly connected to the outer side of the two fixed frames. Each boss has an insertion hole, into which a positioning pin is inserted. The outer side of the mounting surface has multiple symmetrical circular holes, the inner walls of which are inserted into the outer side of the positioning pins on the same side. Each of the positioning pins has two symmetrical rubber rings on its outer side. The inner walls of the insertion holes on the bosses have two annular grooves, the inner walls of which are fitted into the outer side of the rubber rings on the same side. Each positioning pin has a fixed magnet piece connected to its outer side, which is positioned above the two rubber rings. Each boss has an iron ring on its outer side, which is attached to the opposite side of the magnet piece on the same side.

[0007] In a preferred embodiment, the applicability enhancement module includes multiple receiving frames. Each of the two fixed frames has symmetrical narrow slots. The inner walls of the narrow slots are fixedly connected to the outside of the receiving frame on the same side. The inner walls of the receiving frames are slidably connected to the outside of the slide rail on the same side. Each of the multiple receiving frames has a circular opening, and a threaded rod is provided within each circular opening. The threaded rod is movably connected to the opposite side of the outside of the slide rail on the same side.

This reduces the occurrence of wavy light-emitting surfaces, bright and dark stripes when illuminating adjacent walls, and the light strip being partially suspended or subjected to top pressure, which can lead to fatigue fracture of internal solder joints. It also effectively improves the convenience of installation and enables rapid deployment of the light strip body. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] The LED light strip disclosed in this invention is easy to install and fix, and is mainly used in scenarios where the installation effect of existing LED light strips on irregular surfaces is poor.

[0022] Reference Figures 1-10 An easy-to-install and fix LED light strip includes a mounting surface 1. Two mutually perpendicular fixing frames 2 are provided on the outside of the mounting surface 1. A connecting plate 3 is provided at one end of each fixing frame 2. The two connecting plates 3 are mutually perpendicular, and the same light strip body 4 is provided on both fixing frames 2 and connecting plates 3. An applicability enhancement module 6 is provided on each of the two fixing frames 2 and connecting plates 3. The same adaptive flatness control module 5 is provided on both fixing frames 2 and connecting plates 3. The adaptive flatness control module 5 includes two mutually perpendicular hollow soft pads 501. The outside of each hollow soft pad 501 is in contact with the outside of the mounting surface 1. Each hollow soft pad 501 is connected to the opposite side of the outside of the fixing frame 2 on the same side by bolts. The exterior of the light strip body 4 is provided with multiple equidistantly symmetrically distributed trapezoidal sliders 504. The exterior of the trapezoidal sliders 504 on the same side is slidably connected to the same slide rail 506. The slide rails 506 are all located within the fixed frame 2. The two fixed frames 2 are each provided with a wave-shaped elastic plate 505. The exterior of the wave-shaped elastic plate 505 is in contact with the hollow soft pad 501 on the same side and the exterior of the light strip body 4. The exterior of the two connecting plates 3 is provided with the same arc panel 520. The arc panel 520 has a stepped groove 521. The inner wall of the stepped groove 521 is in contact with the exterior of the light strip body 4. The arc panel 520 is provided with a carbon wire 526. The exterior of the carbon wire 526 is in contact with the exterior of the light strip body 4.

[0023] Specifically, the device utilizes an adaptive flatness control module 5 to prevent unevenness defects such as pits, sand particles, joint protrusions, and corners on the wall and panel surfaces during the installation of the light strip body 4. This avoids situations where the light strip body 4 bends, delaminates, warps, or arches due to unevenness caused by the wall and panel surfaces, such as pits, sand particles, joint protrusions, and corners. This reduces the occurrence of wavy light-emitting surfaces, bright and dark stripes when illuminating adjacent walls, partial suspension of the light strip, or pressure on the top, which can lead to fatigue fracture of internal weld points. Furthermore, it effectively improves the convenience of installation and enables rapid deployment of the light strip body 4.

[0024] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7In a preferred embodiment, the exterior of both connecting plates 3 is bolted to the exterior of the mounting surface 1. Both connecting plates 3 have two symmetrical rotating rods 515 rotatably connected to their exteriors via bearings. On opposite sides of the two rotating rods 515 on the same connecting plate 3, a carbon fiber wire 516 is bolted to each other. The exteriors of both carbon fiber wires 516 are flush with the exterior of the light strip body 4. Two symmetrical elastic springs 517 are bolted to the exterior of the connecting plates 3. The ends of the elastic springs 517 away from the connecting plates 3 are bolted to the exterior of the rotating rods 515 on the same side, and the other ends of the elastic springs 517 abut against the rotating rods 515. A space is provided between the two connecting plates 3. A common rotating shaft 518 is provided, and one end of two connecting plates 3 is rotatably connected to the outside of the rotating shaft 518. A pair of connecting brackets 519 are rotatably connected to the outside of the rotating shaft 518 via bearings. The connecting brackets 519 are bolted to the opposite side of the outside of the arc panel 520, and a rectangular groove 523 is provided on the connecting brackets 519. A movable rod 524 is slidably connected in the rectangular groove 523. Two symmetrical springs 525 are bolted to the outside of the movable rod 524. The ends of the two springs 525 away from the movable rod 524 are bolted to the outside of the arc panel 520. A fitting groove 522 is provided on the stepped groove 521, and the inner wall of the fitting groove 522 slides against the outside of the carbon wire 526. The carbon fiber wire 526 is connected to both ends of the movable rod 524 by bolts. Each of the multiple trapezoidal sliders 504 has symmetrical through holes, and the inner wall of each through hole has multiple circumferentially spaced grooves 511. A single constraint frame 514 is slidably connected within the grooves 511 on the same side. A rubber pad 512 is bolted to the side of the constraint frame 514 closest to the light strip body 4, and the rubber pad 512 is in contact with the opposite side of the light strip body 4. Neodymium magnets 513 are installed within each constraint frame 514, and the opposite side of the neodymium magnets 513 is bolted to the rubber pad 512. Multiple symmetrical bosses 50 are bolted to the exterior of both fixed frames 2. 2. Each boss 502 has an insertion hole, and each insertion hole has a positioning pin 503 inserted into it. The outer side of the mounting surface 1 has multiple symmetrical circular holes, and the inner wall of each circular hole is inserted into the outer side of the positioning pin 503 on the same side. Each of the multiple positioning pins 503 has two symmetrical rubber rings 508 on its outer side. Each insertion hole on the multiple bosses 502 has two annular grooves 507 on its inner wall, and the inner wall of each annular groove 507 is fitted into the outer side of the rubber ring 508 on the same side. Each positioning pin 503 has a magnet 509 connected to its outer side by bolts. The magnet 509 is positioned above the two rubber rings 508. Each boss 502 has an iron ring 510 on its outer side, and the iron ring 510 is attached to the opposite side of the magnet 509 on the same side.

[0025] In specific application scenarios, the adaptive flatness control module 5 is mainly used in the adaptive flatness control process. Specifically, the adaptive flatness control module 5, through the insertion and engagement of the positioning pin 503 and the protrusion 502, combined with the fitting design of the annular groove 507 and the rubber ring 508, achieves rapid alignment and stable fixation of the fixing frame 2 on the mounting surface 1, avoiding tedious adjustment steps. The hollow soft pad 501 can closely adhere to the mounting surface 1 and absorb local protrusions or depressions through its own deformation. The wave-shaped elastic plate 505 can stretch or contract with the deformation of the mounting surface 1, and its peaks and troughs always remain relatively parallel, thus continuously and evenly pressing the light strip body 4, ensuring overall stability and reducing the requirements for the flatness of the mounting surface 1. The attraction force of the neodymium magnet 513 drives the constraint frame 514 to slide, causing the rubber pad 512 to automatically clamp the outside of the light strip body 4 without manual tightening. The magnetic force is constant and reliable, ensuring long-term stability. The use of carbon fiber 516 and the rotating rod 515, in conjunction with the elastic spring 517, ensure that the rotating rod 515 is always perpendicular to the connecting plate 3, providing stable support and guidance for the light strip body 4. At the curved panel 520, the threading space can be temporarily expanded by pulling the carbon fiber 526. After releasing, the spring 525 automatically returns to its original position, keeping the light strip body 4 tightly against the inner wall of the stepped groove 521, reducing the resistance when the light strip body 4 passes through the corner, avoiding jamming or damage. Furthermore, the transparent carbon fiber 516 and carbon fiber 526, after wrapping around the outside of the light strip body 4, will not obstruct or affect the light generated by the light strip body 4, ensuring the light intensity of the light strip body 4. The hollowed-out soft pad 501, the wavy elastic plate 505, and other multi-layer elastic elements work together to effectively absorb the stress caused by the unevenness of the mounting surface 1, reduce the local stress concentration of the light strip body 4, and extend the service life of the light strip body 4 and the fixing structure.

[0026] Reference Figure 8 , Figure 9 and Figure 10In a preferred embodiment, the applicability enhancement module 6 includes multiple receiving frames 601. Each of the two fixed frames 2 has symmetrical narrow slots. The inner walls of the narrow slots are bolted to the outer sides of the receiving frames 601 on the same side. The inner walls of the receiving frames 601 are slidably connected to the outer sides of the slide rails 506 on the same side. Each of the multiple receiving frames 601 has a circular opening, and each circular opening contains a threaded rod 602. The threaded rod 602 is rotatably connected to the opposite side of the slide rail 506 on the same side via a bearing. Each of the multiple receiving frames 601 has two symmetrical circular rods 610 on its outer side. The ends of the two circular rods 610 on the same side away from the receiving frame 601 are bolted to the same unifying ring 609. Each threaded rod 602 has an external toothed ring 604 on its outer side. The external toothed ring 604 is rotatably connected to the opposite side of the receiving frame 601 via a bearing. The ends of the threaded rods 602 away from the receiving frame 601 are bolted to a knob 603. Multiple external toothed rings 604... Each of the components is externally equipped with a transmission frame 606, each transmission frame 606 having two symmetrical small holes. The inner walls of the small holes are slidably connected to the outer side of the round rod 610 on the same side. Two symmetrical zigzag plates 607 are bolted to the outside of each transmission frame 606, and two symmetrical pry plates 608 are also provided on the outside of each transmission frame 606. The pry plates 608 are rotatably connected to the outside of the receiving frame 601 via bearings. The end of the pry plate 608 closest to the transmission frame 606 is close to the zigzag plate 607. The side of the receiving frame 601 is in contact; multiple transmission frames 606 are all bolted to the side away from the receiving frame 601 with an inner toothed ring 605. The inner wall of the inner toothed ring 605 is engaged with the outside of the outer toothed ring 604. The side of the inner toothed ring 605 away from the receiving frame 601 is provided with a bonding piece 612. The outside of the bonding piece 612 is bolted to a second spring 611. The end of the second spring 611 away from the bonding piece 612 is bolted to the outside of the same side of the unifying ring 609.

[0027] In specific application scenarios, the applicability enhancement module 6 is mainly used in the applicability enhancement process. That is, the applicability enhancement module 6 drives the threaded rod 602 through the knob 603 to move the slide rail 506 in the receiving frame 601, which can steplessly adjust the distance between the two slide rails 506, so that the device can adapt to various light strip bodies 4 with different widths or thicknesses without replacing parts, significantly improving versatility. Simply press the pry plate 608 to release the lock between the inner toothed ring 605 and the outer toothed ring 604, turn the knob 603 to complete the distance adjustment, and after releasing the pry plate 608, the spring 611 automatically resets and locks. The whole process does not require special tools, saving time and effort and facilitating on-site construction. The threaded rod 602 transmission method realizes continuous micro-adjustment of the distance between the slide rails 506, which can be finely set according to the actual size of the light strip body 4, avoiding damage to the light strip body 4 due to excessive clamping or falling off due to excessive looseness. The adjustment mechanism and the locking mechanism are both integrated in the receiving frame 601, without increasing the external volume, which is conducive to the arrangement of the device in narrow corners or compact installation surfaces 1.

[0028] Working principle: After determining the installation position, the positioning pin 503 is driven into the insertion hole on the protrusion 502 to fix the entire structure on the mounting surface 1. Then, the two connecting plates 3 are fixed on the mounting surface 1, with the two connecting plates 3 set at 90 degrees respectively located on the two sides of the corner on the mounting surface 1. The protrusions 502 on the two mutually perpendicular fixing frames 2 are aligned with the corresponding positioning pins 503, and light pressure is applied to insert the positioning pins 503 into the protrusions 502, ensuring that the annular groove 507 and the rubber ring 508 are fully engaged. At this time, the magnet piece 509 and the iron ring 510 attract and adhere to each other, so that the hollow soft pad 501 connected to the fixing frame 2 can be pressed tightly against the surface of the mounting surface 1, overcoming the attraction between the neodymium magnets 513 and pushing open the constraint frame 514 containing the neodymium magnets 513. The neodymium magnets 513 are moved away from each other, and the trapezoidal slider 504 is aligned with the edge of the light strip body 4. The edge of the light strip body 4 is made of metal or has a magnet with the opposite magnetic properties to the neodymium magnets 513. Under the attraction of the neodymium magnets 513, the neodymium magnets 513 drive the constraint frame 514 to slide on the groove 511 towards the light strip body 4, thereby causing the neodymium magnets 513 to push the rubber pad 512 to tightly clamp the outside of the light strip body 4. After completion, the trapezoidal slider 504 is aligned with the slide rail 506 and slid in, and one end of the light strip body 4 is slid in from the upper fixing frame 2. When passing the position of the connecting plate 3 and the arc panel 520, one end of the light strip body 4 passes through the space formed by the carbon wire 516 and the rotating rod 515, so that the outside of the light strip body 4 rests on the carbon wire 516. On line 516, the elastic spring 517 ensures that the rotating rod 515 is always perpendicular to the connecting plate 3. When one end of the light strip body 4 passes through the curved panel 520, it overcomes the elastic force of the first spring 525 to pull the second carbon wire 526, causing the second carbon wire 526 to drive the movable rod 524 towards the curved panel 520, thereby expanding the space between the second carbon wire 526 and the curved panel 520, allowing one end of the light strip body 4 to pass through easily. After completion, one end of the light strip body 4 is passed through the fixing frame 2 on the other side of the corner of the mounting surface 1, and the second carbon wire 526 is released. Under the elastic force of the first spring 525, the movable rod 524 tightens the second carbon wire 526 and embeds it into the fitting groove 522, thereby driving the outer surface of the light strip body 4 to tighten. The perforated pad 501, attached to the inner wall of the stepped groove 521, absorbs any protrusions or depressions that may exist on the surface of the mounting surface 1 through its own deformation after being tightly attached to the surface of the mounting surface 1. The portion that the perforated pad 501 cannot absorb will cause the corrugated elastic plate 505 to stretch or contract. During this process, the crests and troughs on the corrugated elastic plate 505 will always remain relatively parallel, thus pressing tightly against the surface of the light strip body 4. When the device is used to install light strip bodies 4 of different sizes, the pry plate 608 is pressed according to the size of the light strip body 4. The pry plate 608 rotates and pries up the zigzag plate 607, thereby causing the transmission frame 606 connected to the zigzag plate 607 to push the internal gear ring 605 to move outward against the elastic force of the spring 611.This releases the lock between the internal gear ring 605 and the external gear ring 604. Rotating the knob 603 causes the threaded rod 602 to rotate, which in turn causes the slide rail 506 to slide within the receiving frame 601, changing the spacing between the slide rails 506 to accommodate different sizes of the light strip body 4. After adjustment, the above steps are reversed to relock the external gear ring 604 with the internal gear ring 605, and the threaded rod 602 stops rotating.
