Description

Technical Field

[0002] Neon light strips, with their rich colors and diverse shapes, are widely used in commercial building decoration, home decoration, entertainment venues, commercial advertising, and vehicle decoration. In commercial building decoration, neon light strips are often used to highlight the building outline or window edges to attract customers' attention; in home decoration, neon light strips can be installed on ceilings, walls, or furniture edges to create a warm, romantic, or fashionable atmosphere. However, existing neon light strips have some problems in use. Currently, the light panels of neon light strips on the market are in a single strip shape, which can only be bent in one direction, limiting their use in complex shapes and varied application scenarios. In addition, when existing neon light strips are bent, the internal circuitry is prone to breakage due to uneven stress, rendering the entire strip unusable, increasing usage costs, and affecting lighting effects and lifespan. In some special environments, such as extremely cold environments, the failure rate of neon light strips is even higher, and their reliability is lower.

[0003] Therefore, how to improve the bending performance and reliability of neon light strips has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0036] This utility model is as follows Figures 1 to 17 As shown, a flexible neon light strip that can be bent arbitrarily includes a covering substrate, a flexible light panel, a light-transmitting strip, a flexible conductive base, a plug, and a tail plug, wherein:

[0037] The covering substrate has a receiving cavity for accommodating the flexible lamp plate and the flexible conductive base, and the flexible lamp plate and the flexible conductive base are located in the receiving cavity.

[0038] The flexible light panel is formed by attaching several LEDs and resistors onto a flexible board using a high-speed pick-and-place machine. The flexible light panel comprises multiple flexibly connected light-emitting units, each equipped with an LED bead. The flexible conductive base includes a flexible base and multiple braided wires threaded through it. Each light-emitting unit is electrically connected to one of the braided wires, and each unit is independently emitting light. Holes are provided between adjacent light-emitting units. When the flexible light panel is bent under stress, the area around the holes will break due to stress concentration, but the electrical connection of the light-emitting units remains unaffected, allowing them to continue emitting light independently. This avoids excessive torsional stress on the entire light strip, improving its overall torsional resistance and enabling the strip to bend freely while maintaining its light-emitting function. Furthermore, in practical use, the strip can be cut along the holes to the required length, forming a single light-emitting unit or multiple connected units to meet the application needs of different lengths, enabling completely independent DIY operation.

[0039] The light-transmitting light strip is located at the opening above the accommodating cavity and covers the flexible light panel. The LED beads can diffuse the emitted light through the light-transmitting light strip, making the light output of the flexible light strip uniform. The plug and tail plug are respectively installed at both ends of the covering substrate.

[0040] The lower surface of the flexible light panel is in close contact with the upper surface of the flexible base, which is made of a soft material such as silicone. The two are tightly bonded together, so when the light strip is bent under stress, the flexible light panel and the flexible base, as a whole, are subjected to torsional force and deform synchronously. This avoids damage caused by mutual friction due to mutual torsion caused by gaps between them. Furthermore, the flexible base provides high toughness to the light strip as a whole, distributing a large amount of torsional stress and giving the light strip high bending strength.

[0041] The flexible base has multiple base soldering holes spaced apart for each braided wire, and the flexible lamp board has multiple lamp board soldering holes corresponding to the base soldering holes. The base soldering holes and lamp board soldering holes contain solder paste for soldering the flexible lamp board and braided wires together. The lamp board soldering holes are larger than the base soldering holes, and the solder paste completely fills the lamp board soldering holes, allowing the flexible lamp board and braided wires to be firmly connected by solder, improving conductivity stability. Simultaneously, the soldering operation is convenient, improving product assembly efficiency.

[0042] The flexible base has multiple rectangular wire-passing holes arranged longitudinally side by side, and the cross-section of the braided wire corresponds to the rectangular wire-passing holes. Compared to traditional circular wires which are subjected to force 360 ​​degrees when bent, the braided wire has a stress-free side when bending with the flexible base. This stress-free side forms a clearance space between itself and the inner wall of the wire-passing hole, reducing the bending resistance of the flexible base, improving bending flexibility and bending strength, and enabling it to adapt to large-amplitude, arbitrary-direction, and angle bending operations, thus adapting to different application scenarios.

[0043] Furthermore, all the braided wires are braided tin-plated copper wires. The copper wire material combined with the braiding process effectively improves conductivity and flexibility, extending the product's lifespan. It should be noted that the number of braided wires can be set as needed. The attached diagram shows circuit connection diagrams with four, five, and six braided wires, corresponding to different colored LED beads; the four, five, and six wires include a grounding wire, which is not shown in the diagram.

[0044] The covering substrate includes a bottom wall and two side walls. A notch is formed at one end of the bottom wall, and a rigid adapter plate is installed in the notch. The ends of the braided wires are welded to the rigid adapter plate. Conductive wires are connected to the rigid adapter plate, and the conductive wires extend outward from the outer side of the covering substrate. The ends of the multiple braided wires are respectively connected to conductive tabs, and the conductive tabs are welded to the rigid adapter plate.

[0045] The lower end of the light-transmitting light strip has a receiving groove for accommodating the LED beads, which extend into the receiving groove to effectively concentrate the light emission angle of the LED beads and emit light from the bottom of the light strip; and transparent silicone plugs are installed at both ends of the light-transmitting light strip to improve the waterproof performance of the light strip.

[0046] A processing method for the aforementioned flexible neon light strip that can be bent at will includes the following steps:

[0047] S1. Place the silicone into the mold, and then the mold is used to mold a flexible base.

[0048] S2. Insert multiple braided wires into the wire holes of the flexible base to form a strip-shaped flexible conductive base;

[0049] S3. Solder the braided wires in the base welding holes of the flexible base with a soldering iron; then align the lamp board welding holes of the flexible lamp board with the base welding holes of the flexible base one by one, and then solder the braided wires to the flexible lamp board with a soldering iron to form an electrical connection.

[0050] S4. After the flexible conductive base and flexible lamp board are welded together and the aging test performance is OK, the silicone is extruded through the extrusion molding equipment and then put into the high-temperature vulcanizing furnace to form a semi-finished product.

[0051] S5. A notch is machined at one end of the semi-finished product using a glue-cutting jig. The rigid adapter plate is inserted into the notch, and then the braided wires are firmly soldered to the rigid adapter plate using a soldering iron or wire bonding machine. The conductive wires are then soldered to the rigid adapter plate respectively using a soldering iron or wire bonding machine.

[0052] S6. Insert the transparent silicone plugs into both ends of the semi-finished product and seal the end faces by injecting transparent silicone glue.

[0053] S7. Place the end of the semi-finished product with the conductive wire welded to it into the hole of the plug mold to form a plug, and place the other end into the hole of the tail plug mold to form a tail plug. The processing is complete.

[0054] The manufacturing process for the plugs and tail plugs involves inserting one end of the pre-processed semi-finished product (with a conductive wire welded to it) into the plug mold cavity to form a plug, and the other end into the tail plug mold cavity to form a tail plug. The plugs and tail plugs are made of liquid silicone A and B, mixed 1:1 using a silicone injection molding machine and injected into the mold (first, a transparent silicone plug is inserted into the hole on the end face of the light-transmitting strip, and the remaining small holes are sealed with transparent silicone glue). This prevents the liquid silicone from flowing into the light strip during injection molding, forming an integral part with one end of the light strip. The mold is pre-set to a constant temperature between 140-180 degrees Celsius and a pre-set mold opening time between 80-120 seconds. The injected liquid silicone and silicone sealing film fully vulcanize under the pre-set temperature and time, becoming solid and forming a single unit with the sleeve. This method offers high production efficiency, a simple structure, and excellent sealing, achieving an IP67 water immersion protection level.

[0055] The key design feature of this invention lies in its ability to create a flexible neon light strip by combining a substrate, a flexible light panel, a translucent light strip, a flexible conductive base, a plug, and a tail plug. This neon light strip can be bent in any direction and angle to meet various application scenarios. Furthermore, the flexible light panel in this light strip is composed of multiple interconnected light-emitting units, which are quickly connected to the flexible conductive base via welding for power generation. This allows for quick and convenient operation, forming multiple independent light-emitting units. Users can freely cut and customize the strip according to their needs, offering flexibility, convenience, and a wide range of applications.

[0056] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
