Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED light strip technology, and in particular to an LED light strip mounting and locking structure. Background Technology
[0002] LED light strips, as a common lighting element, are widely used in advertising light boxes, display case lighting, and interior decoration due to their advantages such as uniform light emission, energy efficiency, and compact size. LED light strips are typically made with flexible circuit boards or rigid PCBs as the substrate, on which LED chips are soldered. In practical applications, to meet the lighting needs of different scenarios, multiple LED light strips are often spliced together or fixed to carriers such as light frames and chassis. Therefore, the reliability of the installation structure directly affects the stability and lifespan of the light strip.
[0003] Currently, there are various traditional LED strip installation methods, including adhesive bonding and magnetic attachment. Among them, magnetic attachment is widely used due to its ease of operation. For example, in chassis lighting, magnets are attached to the back of the strip, allowing it to be quickly fixed to an iron carrier using magnetism. However, this method has significant limitations in certain environments. First, in high-temperature environments (such as near heat sources or prolonged high-brightness operation causing the strip to heat up), the magnets are prone to demagnetization because they exceed their operating temperature (e.g., the upper temperature limit of neodymium iron boron magnets is typically 150℃). High temperatures can... Disruption of the magnetic domain arrangement order leads to magnetic attenuation. Secondly, in humid or corrosive environments, the magnet surface is easily oxidized and corroded if there is no protective coating (especially for neodymium iron boron materials), further weakening the magnetism. In addition, physical impacts such as vibration or collision can also disrupt the magnetic domain orientation and accelerate magnetic decay. Once the magnetic force decreases, the connection between the light strip and the light frame will fail, causing the light strip to fall off. More importantly, traditional magnets are mostly fixed to the back of the light strip by adhesive or embedding, making it difficult to replace them individually. Users often need to replace the entire light strip, which increases maintenance costs and wastes resources.
[0004] Furthermore, we disclose an LED light strip mounting and locking structure to meet the practical needs of existing LED light strips that are prone to failure when using adhesive or magnetic connection methods in special environments. Utility Model Content
[0005] In view of this, the purpose of this utility model is to propose an LED light strip installation and locking structure to solve the problem that LED light strips are prone to failure when using adhesive or magnetic connection methods in special environments.
[0006] Based on the above objectives, this utility model provides an LED strip mounting and locking structure, including a lamp frame and a strip body. The lamp frame has an internal mounting groove, and the strip body is mounted inside the mounting groove. Multiple LED beads for emitting light are evenly spaced on the strip body. Multiple lamp body fixing blocks are arranged between adjacent LED beads along the length direction. The lamp body fixing blocks are located on the opening side of the mounting groove. Limiting grooves are formed on both sides of the inner wall of the mounting groove, allowing the lamp body fixing blocks to be limited within the limiting grooves inside the mounting groove. The lamp body fixing blocks are used to limit the position of the strip body. Lamp body covers are provided on each of the multiple lamp body fixing blocks within the mounting groove. The lamp body covers are fitted over the outside of the lamp body fixing blocks to prevent dust from entering and to limit the position of the lamp body fixing blocks within the upper limiting grooves of the mounting groove. DC sockets are provided at both ends of the strip body along the length direction inside the mounting groove. The DC sockets are electrically connected to the strip body for supplying power to the strip body.
[0007] Preferably, the lamp body cover is rectangular in shape, and the two short sides of the lamp body fixing block are fixedly connected with fixing protrusions. The corners of the fixing protrusions are rounded, and the upper surface of the lamp body fixing block is provided with a tool groove.
[0008] Preferably, the lamp body cover has a limiting semicircular groove on both sides, and the inner wall of the limiting semicircular groove fits against the outer wall of the lamp bead on the lamp strip during installation.
[0009] Preferably, positioning feet are fixedly connected to the lower ends of both sides of the lamp body cover, and the lamp body cover is snapped into the limiting groove inside the mounting groove by the positioning feet.
[0010] Preferably, the lamp body cover has ribs fixedly connected to both sides of its interior, and when the lamp body cover is installed on the mounting groove, the ribs on both sides of its interior are in contact with the sides of the lamp body fixing block.
[0011] Preferably, both sides of the outer wall of the DC holder are fixedly connected with a cover fixing key, and the DC holder is slidably engaged in the mounting groove by the cover fixing key. The DC holder has a mounting hole for installing a locking screw to limit the position of the DC holder in the mounting groove.
[0012] Preferably, the side of the DC socket away from the lamp strip body is a DC plug guide surface, and the DC plug guide surface is designed with an inclination to facilitate the insertion of an external DC plug into the interior of the lamp frame.
[0013] The beneficial effects of this utility model are: This LED strip mounting and locking structure eliminates reliance on magnetism through a purely mechanical locking mechanism. This allows it to maintain extremely high connection reliability even in harsh environments where traditional magnetic mounting methods are prone to failure, such as high temperatures and vibrations. Specifically, by rotating the lamp body fixing block, the fixing protrusions on it engage with the pre-set limiting grooves within the mounting slot, achieving a rigid connection between the strip body and the frame. More importantly, the added lamp body cover applies continuous lateral pressure to both sides of the fixing block through its internal ribs, and adheres to the outer wall of the LED beads, forming a double limiting effect. This multi-point mechanical locking method ensures that the connection strength will not decrease due to changes in ambient temperature or long-term use. It fundamentally solves the problems of connection failure and strip detachment caused by magnet demagnetization at high temperatures and weakening of magnetism under vibration and impact. It is particularly suitable for applications with stringent stability requirements, such as industrial lighting and outdoor advertising.
[0014] This LED strip mounting and locking structure enables modular maintenance and reduces long-term operating costs. With traditional magnetic strips, once the magnet on the back weakens, users often have to replace the entire strip because the magnet is usually glued or embedded. In this structure, the core of the strip's fixation—the strip fixing block—is an independent and operable component. When disassembly and maintenance are needed, simply insert a simple tool into the tool slot and rotate it in the opposite direction to unlock and easily remove the strip. This design allows users to replace specific worn parts individually, or only the strip itself, without discarding the entire frame structure. Furthermore, the DC plug guide surface on the DC socket is designed with an angle to guide the DC plug during insertion, reducing insertion resistance and making it suitable for blind insertion in confined spaces, thus improving installation efficiency.

[0020] like Figures 1 to 7 As shown, an LED light strip mounting and locking structure is mainly used to solve the problems of unreliable connection, difficulty in replacement, and poor environmental adaptability when traditional LED light strips are installed by magnetic or adhesive methods. The structure includes a light frame 1 and a light strip body 2. The light frame 1 is usually made of aluminum profile or engineering plastic, and has a mounting groove 3 extending along the length direction inside. The light strip body 2 uses a flexible circuit board or PCB rigid board as the substrate, and welds multiple evenly spaced LED beads on it. The cross-section of the mounting groove 3 can be designed as a rectangle, and its width is slightly larger than the width of the light strip body 2 to allow the light strip body 2 to be easily inserted but to avoid excessive shaking. DC sockets 4 are also provided on both sides of the light strip body 2 for power supply connection. The overall structure is compact and suitable for advertising light boxes, display cabinets and other scenarios. After the light strip body 2 is embedded in the mounting groove 3, the LED beads on it are exposed from the opening of the mounting groove 3 to achieve the lighting function. The bottom of the mounting groove 3 can be provided with heat dissipation holes or heat dissipation fins to enhance the heat dissipation effect. For example, multiple heat dissipation holes with a diameter of 2mm are opened on the aluminum profile light frame 1. The light strip body 2 is initially limited by the light body fixing block 8. There are multiple light body fixing blocks 8, with one set between each LED bead. The preferred material is wear-resistant engineering plastic such as POM or nylon. The bottom of each light body fixing block 8 is provided with a protruding structure, which can be inserted into the preset limiting groove 15 in the mounting groove 3. The depth of the limiting groove 15 is generally 1-2mm, and the width matches the protrusion of the light body fixing block 8, thereby preventing the light strip body 2 from moving longitudinally in the mounting groove 3. The lamp body fixing block 8 is the core component for locking. Each of its two short sides is fixed with a fixing protrusion 10. The height of the fixing protrusion 10 is preferably 1.5mm. The corners are machined with a radius of 0.5mm to reduce friction and facilitate insertion. A tool groove 9 is opened in the middle of the upper end face of the lamp body fixing block 8. The tool groove 9 can be designed as a cross shape, hexagon, or rectangle for use with external tools (such as screwdrivers or special wrenches). During installation, the external tool is inserted into the tool groove 9 and the lamp body fixing block 8 is rotated. The rotation angle is usually 90°, so that the fixing protrusion 10 is inserted into the corresponding limiting groove 15 on the side wall of the mounting groove 3. The shape of the limiting groove 15 is complementary to the fixing protrusion 10, forming an interference fit or a bevel clamping structure, thereby pressing the lamp strip body 2 tightly against the bottom of the mounting groove 3 to achieve mechanical locking. This design avoids the problem of falling off due to magnetic attenuation caused by traditional magnetic attraction methods. It is especially suitable for vibration environments (such as vehicle lighting) or high-temperature environments (the working temperature of the lamp strip can reach above 60°C). The lamp cover 5 is a rectangular cover plate, which can be made of transparent or semi-transparent PC plastic to balance light transmission and protection. It has a limiting semi-circular groove 6 on both sides, and the radius of the semi-circular groove is the same as the radius of the LED lamp bead. When the lamp cover 5 covers the mounting groove 3, the inner wall of the limiting semi-circular groove 6 fits tightly with the outer wall of the LED lamp bead, which not only avoids direct pressure on the lamp bead, but also further restricts the shaking of the lamp strip 2. The lower ends of both sides of the lamp cover 5 are provided with positioning feet 7. The positioning feet 7 are elastic buckle structures that can be locked into the limiting groove 15 on the edge of the mounting groove 3 for fixation. In addition, the inside of the lamp cover 5 is provided with stiffening plates 14 on both sides. The stiffening plates 14 can be 1mm thick. When the lamp cover 5 is installed, the stiffening plates 14 contact the two sides of the lamp body fixing block 8 and apply lateral pressure to prevent the lamp body fixing block 8 from accidentally rotating and loosening in a vibration environment. The covering of the lamp cover 5 also plays a role in dust prevention, reducing the risk of dust entering the mounting groove 3 and affecting heat dissipation or circuit. DC sockets 4 are symmetrically arranged at both ends of the lamp strip body 2. They are connected to the lamp strip body 2 by wires. The outer walls of the DC sockets 4 are provided with cover fixing keys 12. The cover fixing keys 12 are dovetail-shaped or T-shaped protrusions that can slide into the guide grooves on the side walls of the mounting groove 3 to achieve initial positioning. The DC sockets 4 are also provided with mounting holes 11. The diameter of the mounting holes 11 is generally 2.5mm. The DC sockets 4 are fastened to the mounting groove 3 by M2 screws to enhance stability. The end face of the DC sockets 4 away from the lamp strip body 2 is designed as a DC plug guide surface 13. This guide surface is an inclined plane with an inclination angle preferably 15°-30°. When the external DC plug is inserted from the socket of the lamp frame 1, the inclined surface can guide the plug to slide accurately into the interface of the DC sockets 4, reducing insertion resistance. This design is especially suitable for blind insertion in narrow spaces, improving installation efficiency. During installation, first place the light strip body 2 into the mounting groove 3, aligning the protrusion of the light body fixing block 8 with the limiting groove 15. Then, use a tool to rotate the light body fixing block 8 to the locking position. At this time, the fixing protrusion 10 is inserted into the limiting groove 15, and the light strip body 2 is pressed tightly. Next, align the positioning foot 7 of the light body cover 5 with the edge of the mounting groove 3 and press it in. The stiffener 14 forms a lateral limiting on the light body fixing block 8. Finally, fix the DC socket 4 with screws and connect the external power supply. Disassembly can be performed by reversing the operation.
