[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the following is a further detailed description of a flexible neon lens light strip that can withstand arbitrary bending and a manufacturing method thereof in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] Please refer to Figure 1-Figure 5 , a flexible neon lens light strip that can withstand arbitrary bending, comprising:

[0039] The flexible base 100 includes a first side wall 110, a bottom wall 120 and a second side wall 130 connected in sequence, wherein the first side wall 110, the bottom wall 120 and the second side wall 130 form an open groove 140, and the first side wall 110 and the second side wall 130 have a first inclined surface 111 at one end away from the bottom wall 120, and the two first inclined surfaces 111 form a trapezoidal groove 150 expanding outward;

[0040] The flexible circuit board 200 is disposed in the opening groove 140;

[0041] Light source modules 300, a plurality of light source modules 300 are arranged at intervals on the flexible circuit board 200, the light source modules 300 are fixed to the flexible base 100, and the flexible circuit board 200 is provided with a bending margin portion 210 formed by at least one arc-shaped arch 211 between two adjacent light source modules 300;

[0042] The flexible cover plate 400 has second inclined surfaces 410 on both sides. After the second inclined surface 410 is bonded with the first inclined surface 111, the flexible cover plate 400 and the flexible base 100 are co-extruded into one body. A groove 420 is provided on the side of the flexible cover plate 400 facing the bottom wall 120. A gap is formed between the light source module 300 and the flexible cover plate 400 by the groove 420.

[0043] The sleeve is composed of a flexible base 100 and a flexible cover plate 400. The special structure of the contact surface between the two, i.e., the inclined contact structure, can make the contact surface larger when bending, and can better store potential energy. The flexible base 100 and the flexible cover plate 400 are not easy to separate, and the structure is stable, the reliability is strong, and the appearance is beautiful. The light source modules 300 are arranged on the flexible circuit board 200 at intervals, so that the parts between the light source modules 300 can be easily bent; the flexible circuit board 200 is provided with a bending margin part, which has sufficient margin when bending, can ensure the stability of the electrical connection, and avoid the flexible circuit board 200 from breaking or breaking; the flexible cover plate 400 and the light source module 300 have a gap reserved through the groove 420, which can not only facilitate the bending of the flexible cover plate 400, but also prevent the light source module 300 from pushing open the flexible cover plate 400 when the whole is bent forward. Forward bending, lateral bending and even 3D bending are all very convenient. In decoration, according to the changes in the wall structure space, the flexible neon lens 330 light strip also changes accordingly; and it can withstand long-term and multiple bending, which improves product reliability and service life.

[0044] Please refer to Figure 1 , Figure 3 and Figure 4 Each bending allowance portion 210 includes three continuous arc-shaped arches 211. That is, two positive and one negative continuous arc-shaped arches 211 ensure sufficient allowance for stretching during bending.

[0045] Please refer to Figure 2 The light source module 300 includes a heat-resistant substrate 310, an LED lamp bead 320 and a lens 330. The LED lamp bead 320 is mounted on the heat-resistant substrate 310, and the lens 330 is covered outside the LED lamp bead 320 and connected to the heat-resistant substrate 310. Combining the advantages of the neon light strip and the lens 330 light strip, the light is gorgeous and has a focusing effect.

[0046] It is understandable that the heat-resistant substrate 310 can simply strengthen the flexible circuit board 200. Alternatively, as another embodiment, the heat-resistant substrate 310 is a heat-resistant circuit board, the LED lamp beads 320 are electrically connected to the heat-resistant circuit board, and the heat-resistant circuit board is electrically connected to the flexible circuit board 200. The LED lamp beads 320 can be ignited by the heat-resistant circuit board, and the heat-resistant circuit board can be mounted with circuit components to facilitate the adjustment of the LED lamp beads 320. Generally, an FR-4 board can be used as the heat-resistant circuit board.

[0047] Please refer to Figure 2 and Figure 3, and also includes a holder 500, which is arranged in the opening groove 140, and the holder 500 has a limiting hole 510, and the light source module 300 is arranged in the limiting hole 510, and a plurality of deformation grooves 520 are provided on the side of the holder 500. The holder 500 is provided to strengthen the fixation of the lens 330 on the one hand, ensure the stability of the installation of the lens 330, and facilitate the installation of the entire light source module 300 on the other hand, and the deformation grooves 520 are provided so that the holder 500 has a certain deformation ability. Usually, the holder 500 is made of a flexible heat-resistant material, such as heat-resistant plastic, heat-resistant metal or heat-resistant rubber. The holder 500 can be in a long strip type, inserted into the entire opening groove 140, and limited by a male plug and a female plug; or a multi-section type can be adopted, and each section is connected to the flexible base 100. Or, as another trial method, a plurality of limiting grooves are provided in the flexible base 100, and the light source module 300 is directly fixed in the limiting grooves. The light source module 300 is prevented from moving when being bent, thereby ensuring the lighting effect.

[0048] Preferably, the flexible cover plate 400 is made of a transparent material. That is, the light source emitted by the light source module 300 is emitted directly through the flexible cover plate 400. A simple flexible cover plate 400 can be made of transparent resin, transparent silicone, transparent polyvinyl chloride and other materials. Alternatively, as another embodiment, the flexible cover plate 400 is provided with a plurality of avoidance holes corresponding to the light source module 300, and the light source module 300 is exposed or extended from the avoidance holes.

[0049] Please refer to Figure 2 and Figure 3 The outer side surfaces of the first side wall 110, the second side wall 130 and the bottom wall 120 are provided with a plurality of strip grooves 170 extending in the length direction. The provision of the strip grooves 170 facilitates positive deformation and bending. In particular, the outer side walls of the first side wall 110 and the second side wall 130 may also be provided with slide grooves 160 as needed to facilitate the installation of the light strip.

[0050] The present invention also provides a method for manufacturing the above-mentioned flexible silicone neon lens light strip that can withstand arbitrary bending, comprising the following steps:

[0051] The heat-resistant substrate 310 is mounted on the flexible circuit board 200, the LED lamp bead 320 is mounted on the heat-resistant substrate 310, and the lens 330 is covered on the LED lamp bead 320 and fixed to the heat-resistant substrate 310 by welding or gluing to form a light source module 300;

[0052] Mounting the light source module 300 onto the flexible circuit board 200;

[0053] The flexible circuit board 200 between two adjacent light source modules 300 is pre-shaped by die stamping and holding pressure to form a bending allowance portion 210;

[0054] The male plug is electrically connected to one end of the flexible circuit board 200, and the female plug is electrically connected to the other end of the flexible circuit board 200;

[0055] The flexible circuit board 200 is arranged in the flexible base 100, and the light source module 300, the male plug and the female plug are limited and fixed in the flexible base 100; it can be understood that when the holder 500 is set, the flexible circuit board 200 is arranged in the flexible base 100, and then the holder 500 is installed so that the light source module 300 corresponds to the limiting hole 510 of the holder 500;

[0056] The male plug, the female plug, the flexible cover plate 400 and the flexible base 100 are co-extruded.

[0057] The pre-forming allows the bending allowance portion 210 to maintain its shape during installation and to recover its shape after deformation, thereby improving durability.

[0058] The mold for pre-forming includes a bottom mold 610 and a stamping mold 620. The bottom film has a mold groove 611, and the mold groove 611 is the same shape as the preset bending allowance part. The stamping mold 620 is provided with a punching head 621 adapted to the mold groove 611. The stamping mold 620 is connected to a linear moving mechanism for stamping. After the stamping, the stamping mold 620 rises after the pressure is maintained for a period of time. In order to facilitate stamping, a baffle 612 can be set as needed to facilitate the placement of the flexible circuit board 200. It can be understood that the bending allowance part can be formed first and then the light source module 300 can be mounted, or the light source module 300 can be mounted first and then the bending allowance part can be formed, which can be selected according to needs.

[0059] The LED lamp bead 320 can be an SMD type single-color light source or a multi-color light source.

[0060] In particular, the lens 330 is usually made of high temperature resistant materials, such as glass, silica gel, polymer transparent materials, etc., which can be selected according to needs.

[0061] In particular, the flexible circuit board 200 can be in an integrated form, or in a multi-section cascaded form as required.

[0062] It is understandable that the flexible circuit board 200, i.e., the FPC itself has a certain deformation capability, but generally can only deform in one direction, and no creases can appear during deformation, and it cannot be bent at 90 degrees, otherwise it is easy to break. The invention can avoid the appearance of creases by providing a deformation margin portion formed by an arc-shaped arch 211, and can enable the flexible circuit board 200 to deform at multiple angles.

[0063] In particular, the bending allowance portion 210 can be made of a material with elastic deformation ability as a base to enhance the deformation ability, such as superimposing an aluminum film on a polyimide or polyester film by electroplating, coating or gluing.

[0064] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0065] In summary, the present invention provides a flexible neon lens light strip that can withstand arbitrary bending. It is composed of a flexible base and a flexible cover plate to form a sleeve. The special structure of the contact surface between the two, namely the inclined contact structure, can make the contact surface larger when bending, and can better store potential energy. The flexible base and the flexible cover plate are not easy to separate, the structure is stable, the reliability is strong, and the appearance is beautiful. The light source modules are arranged on the flexible circuit board at intervals, so that the parts between the light source modules can be conveniently bent; the flexible circuit board is provided with a bending margin part, which has sufficient margin when bending, can ensure the stability of the electrical connection, and avoid the flexible circuit board from breaking or breaking; the flexible cover plate and the light source module are reserved with a gap through a groove, which can facilitate the bending of the flexible cover plate, and prevent the light source module from pushing open the flexible cover plate when the whole is bent forward; the light source module is fixed in the base by limiting, which can avoid the movement of the light source module to cause the failure of part of the bending margin part, ensure that each bending margin works normally, and avoid the light scattering affecting the lighting effect. Forward bending, lateral bending and even 3D bending are all very convenient. In decoration, according to the changes in the wall structure space, the flexible neon lens light strip also changes accordingly; and it can withstand long-term and multiple bending to improve product reliability and service life.
