However, there are some problems with the existing neon light strips during use. The light panels of the neon light strips currently on the market are in the shape of a whole strip, which can only be bent in a single direction, which limits their use in complex shapes and variable application scenarios. In addition, when the existing neon light strips are bent, the internal circuits are easily broken due to uneven force, which will cause the entire light strip to be scrapped, which not only increases the cost of use, but also affects the lighting effect and service life. In some special environments, such as extremely cold environments, the failure rate of neon light strips is higher and the reliability is lower.

[0044] The present invention Figures 1 to 17 As shown, a flexible neon light strip that can be bent arbitrarily and a processing method thereof, the neon light strip includes a coating substrate, a flexible light board, a light-transmitting light strip, a flexible conductive seat, a plug and a tail plug, wherein:

[0045] The coating substrate has a receiving cavity for receiving the flexible light board and the flexible conductive seat, and the flexible light board and the flexible conductive seat are located in the receiving cavity.

[0046] The flexible light board is formed by pasting a number of LED lamps and a number of resistors on the flexible board by a high-speed chip mounter; the flexible light board includes a plurality of light-emitting units that are flexibly connected in sequence, and each light-emitting unit is provided with an LED lamp bead. The flexible conductive seat includes a flexible base and a plurality of braided wires passing through the flexible base, and the plurality of light-emitting units are electrically connected to the plurality of braided wires respectively, and each light-emitting unit is a light-emitting unit that can emit light independently; and hollow holes are provided between adjacent light-emitting units. When the flexible light board is bent by force, the position where the hollow holes are provided will break due to stress concentration, while the electrical connection of the light-emitting unit is not affected by the break and can still emit light independently, thereby avoiding the entire light strip from being subjected to a large torsional stress, and improving the overall torsional resistance of the light strip; so that the light strip can be bent arbitrarily under the premise of ensuring the light-emitting function. In addition, in actual use, it can be cut along the position of the hollow holes according to the required length to form a single light-emitting unit or multiple light-emitting units connected to meet the application requirements of light strips of different lengths and realize completely independent DIY operation.

[0047] The light-transmitting light strip is located at the upper opening of the accommodating cavity and covers the upper part of the flexible light board. The LED lamp beads can diffuse the emitted light through the light-transmitting light strip, so that the light of the flexible light strip is uniform. The plug and the tail plug are installed at both ends of the covering substrate respectively.

[0048] The lower surface of the flexible light board is in close contact with the upper surface of the flexible base, and the flexible base is made of soft material, such as silicone. The two are closely fitted together. When the light strip is bent under force, the flexible light board and the flexible base are subjected to the twisting force as a whole and deform synchronously, which can avoid mutual distortion caused by the gap between the two and cause damage due to mutual friction; in addition, the flexible base provides high toughness for the light strip as a whole, can share large twisting stress, and make the light strip as a whole have high bending strength.

[0049] The flexible base is provided with a plurality of base welding holes at intervals corresponding to each braided wire, and the flexible lamp board is provided with a plurality of lamp board welding holes corresponding to the plurality of base welding holes, and the base welding holes and the lamp board welding holes contain solder paste for welding the flexible lamp board and the braided wire together. The lamp board welding hole is larger than the base welding hole, and the solder paste completely fills the lamp board welding hole, so that the flexible lamp board and the braided wire can be firmly connected by soldering, thereby improving the conductive stability; at the same time, the welding operation is convenient, thereby improving the assembly efficiency of the product.

[0050] The flexible base is provided with a plurality of rectangular threading holes arranged side by side in the longitudinal direction, and the threading holes corresponding to the cross-section of the braided wire are also rectangular. Compared with the traditional round wire, which is subjected to 360-degree force when bent, the braided wire has a side that is not subjected to force when bent with the flexible base, and an escape space is formed between the side that is not subjected to force and the inner wall of the threading hole, so that the bending resistance of the flexible base is reduced, the bending flexibility and bending resistance are improved, and it can adapt to large-scale bending operations in any direction and angle, and adapt to different application scenarios.

[0051] Furthermore, the plurality of braided wires are all braided tinned copper wires. The copper wire material combined with the braiding process can effectively improve the conductivity and flexibility, and extend the service life of the product. It should be noted that the number of braided wires can be set as needed. The attached figure shows the circuit connection diagram when there are four, five and six braided wires, corresponding to different colored LED lamp beads; four, five and six of them include ground wires, which are not shown in the figure.

[0052] The coating substrate includes a bottom wall and two side walls, a notch is provided at the end of the bottom wall, a hard adapter plate is installed in the notch, the end of the braided wire is welded to the hard adapter plate; and a conductive wire is connected to the hard adapter plate, and the conductive wire extends out of the coating substrate. The ends of the multiple braided wires are respectively connected to conductive plates, and the conductive plates are correspondingly welded to the hard adapter plate.

[0053] The lower end of the translucent light strip has a receiving groove for receiving the LED lamp beads, and the LED lamp beads extend into the receiving groove, so that the light emitting angle of the LED lamp beads is effectively concentrated, and the light is emitted from the bottom of the light strip; and transparent silicone plugs are respectively installed at both ends of the translucent light strip to improve the waterproof performance of the light strip.

[0054] A processing method for the arbitrarily bendable flexible neon light strip comprises the following steps:

[0055] S1, put the silicone into the mold, and then mold the mold to form a flexible base;

[0056] S2, inserting a plurality of braided wires into the threading holes of the flexible base to form a strip-shaped flexible conductive base;

[0057] S3, pre-tinning the braided wire in the base welding hole of the flexible base by using a soldering iron; then, the lamp board welding holes of the flexible lamp board correspond to the base welding holes of the flexible base one by one, and then, using a soldering iron, tinning the braided wire and the flexible lamp board to firmly weld them to form an electrical connection;

[0058] S4. After the welding of the flexible conductive seat and the flexible light board is completed and the aging test performance is OK, it is extruded through the extrusion molding equipment and silicone and then enters the high-temperature vulcanization furnace to form a semi-finished product;

[0059] S5. A notch is processed at one end of the semi-finished product through a rubber cutting jig, and the hard adapter board is inserted into the notch. Then, the braided wire and the hard adapter board are firmly welded by a soldering iron or a wire welding machine through the jig; and the conductive wire is respectively welded to the hard adapter board through a soldering iron or a wire welding machine;

[0060] S6. Insert the transparent silicone plugs into both ends of the semi-finished product and inject the transparent silicone glue to form an end face seal;

[0061] S7. Put one end of the conductive wire welded to one end of the semi-finished product into the hole of the plug mold and injection mold it into a plug. Put the other end into the hole of the tail plug mold and injection mold it into a tail plug. The processing is completed.

[0062] Among them, the production of the plug and the tail plug is specifically to weld one end of the conductive wire at one end of the processed semi-finished product into the hole of the plug mold and also inject it into the plug, and the other end is placed in the hole of the tail plug mold and injected into the tail plug; the plug and the tail plug are made of liquid silicone A and B, which are mixed and injected into the mold in a 1:1 ratio by a silicone injection molding machine (first use a transparent silicone plug to plug the hole on the end face of the light-transmitting light strip, and then inject the remaining small holes into the small holes with transparent silicone glue to form an end face seal), so that the liquid silicone will not flow into the interior of the light strip during injection molding) and form a whole with one end of the light strip. The mold is pre-set to a constant temperature between 140-180 degrees, and the mold opening time is pre-set to 80-120 seconds. The injected liquid silicone and silicone sealing sticker are fully vulcanized through the preset temperature and time to become solid and form a whole with the sleeve. This method has high production efficiency, simple structure and good sealing, and can achieve the protection level of IP67 for water immersion.

[0063] The design focus of the present invention is to form a neon light strip that can be bent arbitrarily by combining a coated substrate, a flexible light board, a light-transmitting light strip, a flexible conductive seat, a plug and a tail plug. The neon light strip can be bent in any direction and angle to meet different application scenarios. In addition, the flexible light board in the light strip is in the form of multiple light-emitting units connected, which are quickly connected to the flexible conductive seat by welding to obtain electricity, and the operation is quick and convenient to form multiple independent light-emitting units; users can perform arbitrary cutting and DIY operations according to their needs, which is flexible and convenient and has a wide range of applications.

[0064] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
