[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further details a flexible neon lens light strip that can withstand arbitrary bending according to the present invention 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.

[0032] Please refer to Figures 1 - 5 , a flexible neon lens light strip that can withstand arbitrary bending, comprising:

[0033] A flexible base 100, comprising a first side wall 110, a bottom wall 120 and a second side wall 130 connected in sequence. The first side wall 110, the bottom wall 120 and the second side wall 130 form an opening groove 140. Both ends of the first side wall 110 and the second side wall 130 away from the bottom wall 120 have a first inclined surface 111, and the two first inclined surfaces 111 form an outwardly expanding trapezoidal groove 150;

[0034] The flexible circuit board 200 is disposed in the opening groove 140;

[0035] 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;

[0036] 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.

[0037] 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, and 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.

[0038] 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.

[0039] 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.

[0040] Understandably, the heat-resistant substrate 310 can merely strengthen the flexible circuit board 200. Or, 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 started by the heat-resistant circuit board, and the heat-resistant circuit board can be surface-mounted with circuit components to facilitate the adjustment of the LED lamp beads 320. Usually, an FR-4 board can be used as the heat-resistant circuit board.

[0041] Please refer to Figure 2 and Figure 3 , it further includes a card seat 500. The card seat 500 is arranged in the opening groove 140. The card seat 500 has a limiting hole 510, the light source module 300 is arranged in the limiting hole 510, and there are several deformation grooves 520 on the side surface of the card seat 500. By setting the card seat 500, on the one hand, the fixation of the lens 330 is strengthened to ensure the stability of the installation of the lens 330, and on the other hand, the installation of the entire light source module 300 is facilitated. At the same time, the deformation grooves 520 are provided to enable the card seat 500 to have a certain deformation ability. Usually, the card seat 500 is made of a flexible heat-resistant material, such as heat-resistant plastic, heat-resistant metal or heat-resistant rubber, etc. The card seat 500 can be in a strip shape and be snapped into the entire opening groove 140 and be limited by a male plug and a female plug; it can also be in a multi-section type, and each section is snap-connected to the flexible base 100. Or, as another embodiment, several limiting grooves are provided in the flexible base 100, and the light source module 300 is directly clamped in the limiting grooves. This avoids the movement of the light source module 300 during bending and ensures the lighting effect.

[0042] Preferably, the flexible cover plate 400 is made of a transparent material. That is, the light source emitted by the light source module 300 directly passes through the flexible cover plate 400 and emits. Simply, the flexible cover plate 400 can be made of materials such as transparent resin, transparent silicone, transparent polyvinyl chloride, etc. Or, as another embodiment, several avoidance holes corresponding to the light source module 300 are provided on the flexible cover plate 400, and the light source module 300 is exposed or protruded from the avoidance holes.

[0043] Please refer to Figure 2 and Figure 3 , a plurality of strip-shaped grooves 170 extending along the length direction are provided on the outer side surfaces of the first side wall 110, the second side wall 130 and the bottom wall 120. By setting the strip-shaped grooves 170, it is convenient for forward deformation and bending. Particularly, sliding grooves 160 can also be provided on the outer side walls of the first side wall 110 and the second side wall 130 according to needs to facilitate the installation of the light strip.

[0044] The LED lamp beads 320 can be SMD type single-color light sources or multi-color light sources.

[0045] Particularly, the lens 330 is usually made of a high-temperature resistant material. Such as glass, silicone, high molecular transparent material, etc., and can be specifically selected according to needs.

[0046] Specifically, the flexible circuit board 200 can be integrally formed or can be spliced and cascaded in multiple segments as needed.

[0047] It can be understood that the flexible circuit board 200, i.e., the FPC itself, has a certain deformation ability, but generally can only deform unidirectionally, and there should be no creases or 90-degree bends during deformation, otherwise it is prone to breakage. The utility model can avoid the appearance of creases and enable the flexible circuit board 200 to deform at multiple angles by providing a deformation margin part formed by an arc-shaped arch 211.

[0048] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0049] In summary, a flexible neon lens light strip that can withstand arbitrary bending provided by the present utility model consists 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 surface contact structure, can make the contact surface larger during bending, better store potential energy, and the flexible base and the flexible cover plate are not easily separated, with stable structure, strong reliability, and beautiful appearance. The light source modules are arranged at intervals on the flexible circuit board, making it convenient to bend the part between the light source modules; the flexible circuit board is provided with a bending margin part, which has sufficient margin during bending to ensure the stability of electrical connection and avoid breakage or open circuit of the flexible circuit board; the flexible cover plate and the light source module reserve a gap through a groove, which can not only facilitate the bending of the flexible cover plate but also prevent the light source module from pushing open the flexible cover plate during overall forward bending; the light source module is fixed in the base through a limit, which can prevent the light source module from moving and causing some bending margin parts to fail, ensure that each bending margin functions normally, and avoid the scattering of light and affecting the lighting effect. Forward bending, lateral bending, and even 3D bending are very convenient. During decoration, according to the changes in the wall structure space, the flexible neon lens light strip can also change accordingly; and it can withstand long-term and multiple bends, improving the reliability and service life of the product.

Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to form equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present utility model.
