Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to a bendable LED decorative light based on a flexible silicone substrate. Background Technology

[0002] The bendable LED decorative light based on a flexible silicone substrate is an innovative product combining flexible materials and LED lighting technology. This light fixture not only inherits the bendable characteristics of the tungsten filament in traditional incandescent bulbs but also incorporates the advantages of LED light sources, such as high efficiency, energy saving, and long lifespan. The flexible silicone substrate allows the LED decorative light to be bent into different shapes and patterns, just like the tungsten filament in traditional incandescent bulbs. This flexibility not only enhances the decorative effect but also allows the light fixture to adapt to various complex installation environments and spatial requirements.

[0003] In current technology, flexible LED decorative lights are typically transported and stored by rolling them up. However, this approach presents some practical inconveniences. Due to the considerable thickness of the LED strip, traditional adhesive tape often fails to provide sufficient adhesion for secure bonding. If cable ties are used, the small contact area between the ties and the LED strip makes them prone to damage. Furthermore, securing the rolled-up LED strip with cable ties is not only difficult to operate but also prone to slippage during use, affecting the performance. More importantly, in actual use, the LED strip often needs to be cut to meet specific requirements, making it difficult to secure the remaining portion effectively. This leads to the strip becoming tangled, reducing user experience and significantly impacting work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flexible LED decorative light based on a flexible silicone substrate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bendable LED decorative light based on a flexible silicone substrate, comprising a decorative light strip and a winding column, wherein an end ring is fixed at the top and bottom of the winding column, a base seat is rotatably connected to the inner wall of the end ring, a sliding moment groove is formed in the inner wall of the base seat, spring plates are fixed on both sides of the inner wall of the sliding moment groove, an extension arm is slidably connected to the inner wall of the sliding moment groove, spring grooves are formed on both sides of the extension arm, a pressure end is fixed at one end of the extension arm, an L-shaped pressure member is fixed at the bottom of the pressure end, and a vertical blocking groove is formed on one side of the L-shaped pressure member.

[0006] Preferably, the top of the end ring has an insert groove, the inner wall of the insert groove has a fixing screw hole, and a fixing ring is fixed to the inner wall of the insert groove by screws. A protective horizontal bar is fixed in a circumferential array on the circumference of the fixing ring. A protective vertical bar is fixed to one end of the protective horizontal bar, and a residual ring component is fixed to one end of the protective vertical bar. One end of the protective vertical bar has a semi-circular shape, and a residual ring groove is formed on the surface of the semi-circular shape. The inner wall of the residual ring groove is slidably connected to the surface of the residual ring component. In the prior art, LED decorative lights, due to their soft characteristics, are particularly susceptible to collisions caused by vehicle bumps during transportation after being coiled up. Because their material itself has low impact resistance, existing packaging methods often rely on a large amount of cushioning materials such as pearl cotton to protect the product. However, these materials are not only expensive but also difficult to recycle, putting pressure on the environment. Furthermore, to fix these cushioning materials, a large amount of film or tape and other auxiliary tools are required, which further increases transportation costs and complexity. More seriously, despite the aforementioned packaging measures, the yield rate remains unsatisfactory. Frequent collisions and improper packaging often lead to damage to the lamps, reducing the overall yield rate. To address this issue, this utility model solves the problem by installing protective vertical strips. Before transportation, workers place the fixing rings in the recessed grooves and secure them with screws using the fixing screw holes. After the upper and lower fixing rings are installed, one end of each protective vertical strip is in contact with the other. Workers can then use a screwdriver or other tools to pull the semi-circular residual ring groove, causing the semi-circular ring to rotate due to the interaction between the residual ring and the residual ring groove. This makes it difficult for the multiple protective vertical strips to detach, thus forming a protective frame through the protective horizontal and vertical strips. This effectively protects the decorative light strips and prevents damage caused by collisions during transportation. Furthermore, the installation of this mechanism only requires a screwdriver and four screws, allowing for easy disassembly and recycling, thereby reducing transportation costs.

[0007] Preferably, one end of the decorative light strip has a fastening groove, and the circumference of the winding post has an insertion groove. An inner shaft is rotatably connected to the inner wall of the insertion groove. A reset spring is provided on the circumference of the inner shaft. Both ends of the inner shaft are fixed with end plates. A fastener is fixed to one side of the end plate, and a composite residual circle is fixed to the other side of the end plate. In the prior art, when the decorative light strip is rolled and wrapped around the winding post, it is usually necessary to use tape or other means to initially fix one end of the light strip to the surface of the winding post. However, this fixing method has significant instability. Whether in daily use or during transportation, it is very easy for it to loosen, which will cause the decorative light strip to unwind. More seriously, this fixing method often leaves obvious adhesive residue on the surface of the winding post. These residues are not only difficult to remove, but also make the winding post almost impossible to recycle. This results in a significant waste of materials, which undoubtedly reduces the user experience, increases operating costs, and also places a burden on the environment. To address this issue, this invention employs a fastener installation method. When a worker curls and wraps a decorative light strip around a post, the worker inserts the round end of the strip with the fastener groove into the groove. Upon contact with the fastener, the round end pushes the fastener outward along its inclined surface, axially from the inner post. Simultaneously, the return spring accumulates elastic potential energy. After the light strip passes through, the return spring releases this energy, causing the fastener to rotate and engage in the groove, preventing the light strip from detaching and thus securing it. When the worker finishes using the light strip, the composite round end can be lifted outward, allowing the fastener to leave the groove and the light strip to detach, thereby improving the user experience.

[0008] Preferably, the composite residual circle has an auxiliary groove on its surface and a release groove at one end, which increases friction through the auxiliary groove and release groove, provides a leverage point for the staff, and improves the user experience.

[0009] Preferably, a positioning magnet is fixed at one end of the semicircle, which enables the positioning magnet to exert an attractive force on the other semicircle, making it easier for staff to position the object and improving the user experience.

[0010] Preferably, grip grooves are provided on both sides of the pressure end, and a rubber layer is provided on the inner wall of the grip groove, so that the grip groove is more ergonomic and the user experience is improved.

[0011] Preferably, a stabilizing block is fixed to one end of the base mount, which prevents the component from tilting when it shrinks, thereby improving the stability of the equipment.

[0012] Beneficial effects:

[0013] 1. In existing technologies, flexible LED decorative lights are typically transported and stored by rolling them up. However, this approach presents several practical inconveniences. Due to the considerable thickness of the light strip, traditional adhesive tape often fails to provide sufficient adhesion for secure bonding. Cable ties, on the other hand, are prone to damage due to their small contact area with the light strip. Furthermore, securing the rolled-up strip with cable ties is not only cumbersome but also prone to slippage during use, affecting the overall performance. More importantly, in practice, the light strip often needs to be cut to size, resulting in unsecured portions that easily become tangled, reducing user experience and significantly impacting work efficiency. To address these issues, this invention employs an L-shaped clamping mechanism. This allows workers to stabilize the decorative light strip by first securing it with a clamping device. The base is rotated around the circumference of the column, and then rotated again within the inner wall of the end ring. When the base rotates to the outer end of the decorative light strip, the operator adjusts the position of the extension arm so that it retracts into the sliding moment groove. The spring plate is embedded in the spring groove to temporarily fix the extension arm until the L-shaped pressure piece at the pressure end presses down on the outer end of the decorative light strip. The L-shaped pressure piece applies pressure to the surface of the decorative light strip to keep it in position. The vertical blocking groove further increases the friction with one end of the decorative light strip to prevent the decorative light strip from loosening. When the operator needs to cut the decorative light strip, the base can be rotated to press it onto the position to be cut, and the cutting blade can be used to cut using the gap at one end of the pressure end. This ensures that the cut is always flat and prevents the blade from being crooked and causing injury to the operator, greatly increasing safety and convenience. With the fixation of this structure, the operator can easily store the item when not in use and does not need further fixation after cutting, thus improving the user experience.

[0014] 2. In existing technologies, LED decorative lights, due to their flexible nature, are particularly susceptible to damage from vehicle bumps during transportation after being coiled up. Because the material itself has low impact resistance, existing packaging methods often rely on large amounts of cushioning materials such as pearl cotton to protect the product. However, these materials are not only costly but also difficult to recycle, putting pressure on the environment. Furthermore, to secure these cushioning materials, a large amount of film or tape is required, further increasing transportation costs and complexity. More seriously, despite these packaging measures, the yield rate remains unsatisfactory; frequent collisions and improper packaging often lead to damage to the lights, reducing the overall yield rate. To address these problems, this utility model adopts... The solution involves installing protective vertical strips. Before transporting the product, workers place the fixing rings in the recessed grooves and secure them with screws using the fixing screw holes. After the fixing rings at both ends are installed, one end of each protective vertical strip is in contact with the others. Workers can then use a screwdriver or other tools to pull on one end of the semi-circular residual ring groove, causing the semi-circular ring to rotate due to the interaction between the residual ring and the residual ring groove. This makes it difficult for the multiple protective vertical strips to detach, thus forming a protective frame through the protective horizontal and vertical strips. This effectively protects the decorative light strip and prevents damage caused by collisions during transport. Furthermore, the mechanism can be installed using only a screwdriver and four screws, allowing for easy disassembly and recycling, thereby reducing transportation costs.

[0015] 3. In existing technologies, when decorative light strips are rolled and wrapped around a post, adhesive tape or similar methods are typically used to initially secure one end of the strip to the post's surface. However, this method is significantly insecure, easily loosening during daily use and transportation, leading to the light strip unraveling. More seriously, this method often leaves noticeable adhesive residue on the post's surface. This residue is not only difficult to remove but also makes the post almost impossible to recycle, resulting in significant material waste. This undoubtedly greatly reduces the user experience, increases operating costs, and also causes environmental damage. To address the issue of excessive burden on the decorative light strip, this invention employs a fastener installation method. When a worker curls and wraps the decorative light strip around a post, they can insert the round end of the strip with the fastener groove into the groove. Upon contact with the fastener, the round end pushes the fastener outward along its inclined surface, axially from the inner post. Simultaneously, the return spring accumulates elastic potential energy. After the decorative light strip passes through, the return spring releases this energy, causing the fastener to rotate and engage in the fastener groove, preventing the decorative light strip from detaching and thus securing it. When the worker finishes using the decorative light strip, the composite round end can be lifted outward, allowing the fastener to leave the groove and the decorative light strip to detach, thereby improving the user experience.

[0027] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0030] Reference Figure 1-9 A bendable LED decorative light based on a flexible silicone substrate includes a decorative light strip 1 and a winding post 101. An end ring 2 is fixed at the top and bottom of the winding post 101. A base seat 201 is rotatably connected to the inner wall of the end ring 2. A sliding moment groove 202 is opened on the inner wall of the base seat 201. Spring plates 203 are fixed on both sides of the inner wall of the sliding moment groove 202. An extension arm 204 is slidably connected to the inner wall of the sliding moment groove 202. Spring grooves 205 are opened on both sides of the extension arm 204. A pressure end 206 is fixed at one end of the extension arm 204. An L-shaped pressure piece 207 is fixed at the bottom of the pressure end 206. A vertical blocking groove 208 is opened on one side of the L-shaped pressure piece 207. The top of the end ring 2 is provided with an inserting groove 3, and the inner wall of the inserting groove 3 is provided with a fixing screw hole 302. A fixing ring 301 is fixed to the inner wall of the inserting groove 3 by screws. A protective horizontal bar 303 is fixed in a circumferential array on the circumference of the fixing ring 301. A protective vertical bar 304 is fixed to one end of the protective horizontal bar 303. A residual ring part 305 is fixed to one end of the protective vertical bar 304. A semi-rotating circle 306 is provided at one end of the protective vertical bar 304. A residual ring groove 307 is provided on the surface of the semi-rotating circle 306. The inner wall of the residual ring groove 307 is slidably connected to the surface of the residual ring part 305. Due to its soft characteristics, LED decorative lights are particularly susceptible to collisions caused by vehicle bumps during transportation after being coiled up. Because the material itself has low impact resistance, existing packaging methods often rely on a large amount of cushioning materials such as pearl cotton to protect the product. However, these materials are not only expensive but also difficult to recycle, putting pressure on the environment. At the same time, in order to fix these cushioning materials, a large amount of auxiliary tools such as film or tape are also required, which further increases the transportation cost and complexity. More seriously, Despite the aforementioned packaging measures, the yield rate remained unsatisfactory. Frequent collisions and improper packaging often led to damage to the lamps, reducing the overall yield rate. The solution was to install protective vertical strips 304. Before transportation, workers placed the fixing rings 301 into the recessed grooves 3 and secured them with screws using the fixing screw holes 302. After the upper and lower fixing rings 301 were installed, one end of each protective vertical strip 304 contacted each other. Workers could then use a screwdriver or similar tool to pull on one end of the residual ring groove 307 of the semi-rotating circle 306, causing the semi-rotating circle 306 to rotate due to the interaction between the residual ring 305 and the residual ring groove 307. This prevented the multiple protective vertical strips 304 from detaching, thus forming a protective frame through the protective horizontal strips 303 and the protective vertical strips 304. This effectively protected the decorative light strip 1, preventing damage from collisions during transportation. Furthermore, the mechanism required only a screwdriver and four screws for installation, facilitating easy disassembly and recycling, thereby reducing transportation costs.

[0031] The decorative light strip 1 has a fastening groove 406 at one end and an insertion groove 4 on the circumference of the winding post 101. An inner shaft post 405 is rotatably connected to the inner wall of the insertion groove 4. A reset spring 401 is provided on the circumference of the inner shaft post 405. End plates 402 are fixed at both ends of the inner shaft post 405. A fastener 403 is fixed on one side of the end plate 402, and a composite residual circle 404 is fixed on the other side of the end plate 402. When the decorative light strip 1 is rolled and wrapped around the winding post 101, it is usually necessary to use tape or other means to initially fix one end of the light strip to the surface of the winding post 101. However, this fixing method has significant instability. It is very easy for it to loosen during daily use or transportation, which will cause the decorative light strip 1 to unwind. More seriously, this fixing method often leaves obvious adhesive residue on the surface of the winding post 101. These residues are not only difficult to remove, but also make the winding post 101 almost impossible to recycle, resulting in a large amount of adhesive residue. The waste of materials undoubtedly greatly reduces the user experience, increases the cost of use, and also puts a certain burden on the environment. This is solved by using fastener 403. Before the decorative light strip 1 is rolled and wrapped around the winding post 101, the worker can insert the round end of the decorative light strip 1 with the fastener groove 406 into the groove 4. When the round end contacts the fastener 403, it pushes the fastener 403 outward along its inclined surface with the inner post 405 as the axis. At the same time, the reset spring 401 accumulates elastic potential energy. After the decorative light strip 1 passes through, the reset spring 401 releases the elastic potential energy, causing the fastener 403 to rotate and fasten into the fastener groove 406, preventing the decorative light strip 1 from detaching outward, thus fixing the decorative light strip 1. When the worker finishes using the decorative light strip 1, the composite residual circle 404 can be lifted outward, causing the fastener 403 to leave the fastener groove 406, allowing the decorative light strip 1 to detach, thus improving the user experience. The composite residual circle 404 has an auxiliary groove 5 on its surface and a release groove 501 at one end. These grooves increase friction, providing leverage points for workers and improving user experience. A positioning magnet 6 is fixed to one end of the semi-rotating circle 306, facilitating positioning and improving user experience. Grip grooves 7 are provided on both sides of the pressure end 206, with a rubber layer 701 on the inner wall, making the grip more ergonomic and improving user experience. A stabilizing block 8 is fixed to one end of the base rotating seat 201, preventing tilting during component retraction and improving equipment stability.

[0032] The working principle of this utility model is as follows: When the operator needs to keep the decorative light strip 1 stable, the decorative light strip 1 is first wrapped around the circumference of the winding post 101. Then, the base rotating seat 201 is rotated, causing the base rotating seat 201 to rotate within the inner wall of the end ring 2. When it reaches the outer end of the decorative light strip 1, the operator adjusts the position of the extension arm 204 so that it retracts into the sliding moment groove 202. The spring plate 203 is embedded in the spring groove 205 to temporarily fix the extension arm 204 until the L-shaped pressing member 207 of the pressing end 206 presses down on the outer end of the decorative light strip 1. The L-shaped pressing member 207 presses against the surface of the decorative light strip 1. Pressure is applied to the surface to maintain its position. The vertical groove 208 further increases the friction with one end of the decorative light strip 1, preventing the decorative light strip 1 from loosening. When the worker needs to cut the decorative light strip 1, the base seat 201 can be rotated to press it onto the position to be cut, and the cutting blade can be used to cut by relying on the gap at one end of the pressure end 206, so that the cut surface always remains flat. Before the product is transported, the worker places the fixing ring 301 in the ring groove 3 and uses screws to fix the fixing ring 301 using the fixing screw hole 302. Then, when the fixing rings at the upper and lower ends are fixed... After the 301 rectangular strip is installed, one end of its protective vertical strips 304 will also be in contact with each other. Workers can use a screwdriver or similar tool to insert into one end of the residual ring groove 307 of the semi-rotating circle 306 and pull it, causing the semi-rotating circle 306 to rotate due to the cooperation of the residual ring 305 and the residual ring groove 307. This makes it difficult for the multiple protective vertical strips 304 to detach, thus forming a protective frame through the protective horizontal strip 303 and the protective vertical strips 304, effectively protecting the decorative light strip 1. Before workers curl and wrap the decorative light strip 1 around the winding post 101, they can use the decorative light strip 1 with its buckle groove... The round end of 406 is inserted into the groove 4. When the round end contacts the fastener 403, it pushes the fastener 403 outward along its inclined surface with the inner shaft 405 as the axis. At the same time, the reset spring 401 accumulates elastic potential energy. When the decorative light strip 1 passes through, the reset spring 401 releases the elastic potential energy, causing the fastener 403 to rotate and snap into the buckle groove 406, preventing the decorative light strip 1 from coming off outward, thus fixing the decorative light strip 1. When the staff finishes using the decorative light strip 1, the composite residual circle 404 can be lifted outward to make the fastener 403 leave the buckle groove 406 and the decorative light strip 1 come off.
