Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to a neon light strip. Background Technology

[0002] Flexible neon light strips are widely used in decorative lighting due to their bendability, but prolonged bending can lead to multiple technical defects: Electrically, bending stress can cause conductive wires to break or solder joints to detach, creating a risk of open circuits; Optically, LED chip misalignment or cracking of the encapsulating adhesive can cause uneven light spots and color temperature drift; Mechanically, plastic deformation of the substrate can form permanent creases, and cracking of the protective layer can weaken waterproofing; In terms of heat dissipation, bending deformation reduces the heat dissipation contact area, accelerating LED light decay. Existing solutions alleviate these problems by enhancing the flexibility of the substrate or locally thickening the structure, but this often sacrifices thinness, heat dissipation efficiency, and cost balance. Therefore, there is an urgent need for a new type of neon light strip that can simultaneously ensure electrical stability, optical consistency, mechanical durability, and heat dissipation efficiency during dynamic bending, breaking through existing technological bottlenecks. Utility Model Content

[0003] In order to overcome at least one of the defects described in the prior art, this utility model provides a neon light strip to solve the problem of how to simultaneously ensure electrical stability, optical consistency, mechanical durability and heat dissipation efficiency of neon light strips during dynamic bending.

[0004] The present invention provides a technical solution to address the problem of a neon light strip, comprising a long strip-shaped housing, a long strip-shaped substrate, and a plurality of LED beads. The substrate is disposed within the housing and both extend in the same direction. The substrate is inclined within the housing along its width. The plurality of LED beads are sequentially spaced on the substrate along its length. At least one side of the substrate has a notch.

[0005] As an optional implementation, in this embodiment of the present invention, the notch is an elongated notch, and the horizontal center line of the notch is inclined to the horizontal center line of the substrate.

[0006] As an optional implementation, in this embodiment of the present invention, multiple notches are provided on both sides of the substrate, and the multiple notches are spaced apart along the length direction of the substrate.

[0007] As an optional implementation, in this embodiment of the present invention, inclined positioning grooves are provided on both sides of the housing, and the two sides of the substrate are respectively inserted into the two positioning grooves.

[0008] As an optional implementation, in this embodiment of the present invention, the housing is further provided with an arc-shaped groove having an arc-shaped light guide surface, and a plurality of the lamp beads are located in the arc-shaped groove and emit light toward the arc-shaped light guide surface.

[0009] As an optional implementation, in this embodiment of the present invention, the substrate consists of multiple pieces, and the neon light strip further includes a plastic support plate. The back sides of the multiple substrates abut against the plastic support plate and are sequentially spliced ​​along the length direction.

[0010] As an optional implementation, in this embodiment of the present invention, solder joints are provided at the splicing points of two adjacent substrates, and the solder joints at the splicing points of two adjacent substrates are welded together to conduct electricity, so that the two adjacent substrates are electrically connected.

[0011] As an optional implementation, in this embodiment of the present invention, the housing includes an outer shell and a light guide. The light guide is disposed inside the outer shell and clamps the substrate inside the outer shell. The plurality of lamp beads emit light toward the light guide, and the light guide directs the light from the lamp beads toward the outer shell.

[0012] As an optional implementation, in this embodiment of the present invention, the outer shell includes a bottom shell and a light amplifying element. The bottom shell is approximately U-shaped.

[0013] Implementing the embodiments of this utility model will have the following beneficial effects:

[0014] This invention comprises a long strip-shaped shell, a long strip-shaped substrate, and multiple LED chips. The substrate is located inside the shell, and both extend in the same direction. The substrate is inclined along its width within the shell, and the multiple LED chips are sequentially spaced on the substrate along its length. At least one side of the substrate has a notch. This design, through the notch design on the substrate sidewall and its synergistic effect with the shell and LED chip layout, achieves the following comprehensive benefits: the notch structure preferentially releases local stress during dynamic bending, significantly reducing the mechanical load on conductive lines and solder joints, and improving bending lifespan; simultaneously, the matching relationship between the notch deformation and LED spacing suppresses chip misalignment and encapsulation cracking; the elastic deformation unit formed by the notch further avoids plastic damage to the substrate, and combined with optimized heat dissipation channels, reduces temperature rise and extends the light decay cycle; furthermore, the redundant design of the notch separation isolates the risk of fault propagation, and combined with lightweight substrate and modular cutting compatibility, achieves a unified technical effect of high reliability, low cost, and multi-scenario adaptability, systematically solving the core technical bottleneck of electrical-optical-mechanical multi-physics coupling failure in dynamic applications of flexible LED strips. Furthermore, since the substrate is inclined within the housing along the width direction, when the substrate is laterally bent, the lateral bending stress is decomposed into shear and normal compression components by the tilt angle, allowing adjacent modules to generate elastic displacement to offset the accumulation of deformation, thus systematically improving mechanical reliability, electrical stability and optical consistency.

[0027] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0028] Please refer to the following: Figures 1 to 4 This utility model discloses a neon light strip, which includes a long strip-shaped shell 1, a long strip-shaped substrate 2, and a plurality of light beads 3. The substrate 2 is disposed inside the shell 1 and the length extension directions of the two are the same. The substrate 2 is inclinedly disposed inside the shell 1 along the width direction. The plurality of light beads 3 are sequentially spaced on the substrate 2 along the length direction of the substrate 2. At least one side of the substrate 2 is provided with a notch 21. By adopting this design approach, the synergistic effect of the notch 21 on the sidewall of substrate 2 and its arrangement with the housing 1 and LED beads 3 can achieve the following comprehensive benefits: the notch 21 structure preferentially releases local stress during dynamic bending, significantly reducing the mechanical load on the conductive lines and solder joints 22, and improving bending life; at the same time, the matching relationship between the deformation of notch 21 and the LED spacing suppresses chip misalignment and encapsulation glue cracking; the elastic deformation unit formed by notch 21 further avoids plastic damage to substrate 2, and combined with the optimization of heat dissipation channels, it reduces temperature rise and extends the light decay cycle; in addition, the redundant design of notch 21 can isolate the risk of fault propagation, and with the compatibility of lightweight substrate and modular cutting, it achieves a unified technical effect of high reliability, low cost and multi-scenario adaptability, systematically solving the core technical bottleneck of electrical-optical-mechanical multi-physics field coupling failure in dynamic applications of flexible light strips. Furthermore, since the substrate 2 is inclined within the housing 1 along the width direction, when the substrate 2 is laterally bent, the lateral bending stress is decomposed into shear and normal compression components by the tilt angle, allowing adjacent modules to generate elastic displacement to offset the deformation accumulation, thus systematically improving mechanical reliability, electrical stability and optical consistency.

[0029] Furthermore, notch 21 is an elongated notch, and the horizontal centerline of notch 21 is inclined to the horizontal centerline of substrate 2. With this design, when substrate 2 is laterally twisted, the inclined design of notch 21 decomposes lateral stress, inhibits linear crack propagation, and improves dynamic fatigue resistance and deformation compensation, systematically optimizing the mechanical reliability, electrical stability and optical uniformity of the light strip when it is laterally twisted.

[0030] Furthermore, multiple notches 21 are provided on both sides of the substrate 2, and the multiple notches 21 are spaced apart along the length direction of the substrate 2. With this design, the multiple notches 21 can work together to more effectively improve the mechanical reliability, electrical stability and optical uniformity of the LED strip when it is laterally twisted.

[0031] Furthermore, in order for the substrate 2 to be fixed at an angle inside the housing 1, inclined positioning grooves 13 are provided on both sides of the housing 1. The two sides of the substrate 2 are respectively inserted into the two positioning grooves 13 to clamp the substrate 2 inside the housing 1.

[0032] In some embodiments, the housing 1 also includes an arc-shaped groove 14 with an arc-shaped light guide surface, and multiple LEDs 3 are located within the arc-shaped groove 14 and emit light towards the arc-shaped light guide surface. This design utilizes a continuous curvature design for the arc-shaped light guide surface, eliminating the sharp-angle total reflection zone of traditional polygonal light guides, thus improving the effective utilization of light flux and suppressing color temperature shift caused by corner scattering. By optimizing the arc surface tilt angle and Fresnel loss compensation, uniform light emission over a wide viewing angle and a uniform light spot are achieved. Simultaneously, the risk of microcrack propagation caused by corner stress concentration is avoided, reducing the fracture rate of the light guide structure under cyclic thermal shock.

[0033] In some embodiments, the substrate 2 consists of multiple pieces, and the neon light strip also includes a plastic support plate 4. The backs of the multiple substrates 2 abut against the plastic support plate 4 and are sequentially spliced ​​along the length direction. With this design, the plastic support plate 4 provides support to the substrates 2, creating a dynamic coupling support between them. That is, the cooperation between the plastic support plate 4 and the substrate 2 with the notch 21 allows the substrate 2 structure to meet the requirements of lateral deformation while maintaining its required structural strength, achieving a multi-directional increase in bending stiffness. This embodiment uses four substrates 2 as an example.

[0034] Furthermore, in order to enable the multiple spliced ​​substrates 2 to conduct electricity, solder joints 22 are provided at the splicing points of adjacent substrates 2. The solder joints 22 at the splicing points of adjacent substrates 2 are welded together to conduct electricity, so that the adjacent substrates 2 are electrically connected.

[0035] In some embodiments, the housing 1 includes an outer shell 11 and a light guide 12. The light guide 12 is disposed inside the outer shell 11 and clamps the substrate 2 inside the outer shell 11. Multiple LED beads 3 emit light toward the light guide 12, and the light guide 12 guides the light of the LED beads 3 to the outer shell 11.

[0036] Furthermore, the outer casing 11 includes a bottom casing 111 and a light amplifying element 112. The bottom casing 111 is approximately U-shaped. The light guide element 12 is disposed inside the bottom casing 111 and clamps the substrate 2 inside the bottom casing 111. The light amplifying element 112 covers the bottom casing 111. The light guide element 12 directs the light from the LED bead 3 to the light amplifying element 112, and the light is ultimately emitted by the light amplifying element 112. It is understood that in other embodiments, the casing 1 can also be designed as a light amplifying element, which is not limited here. Specifically, the bottom casing 111 is made of white silicone light-blocking material, the light amplifying element 112 is made of milky white silicone light amplifying material, and the light guide element 12 is made of transparent silicone light guide material.

[0037] As described above, the substrate 2 is inserted into two positioning grooves 13 on both sides and clamped within the housing 1. Correspondingly, the positioning grooves 13 are formed between the light guide 12 and the bottom housing 111.

[0038] The present invention provides a neon light strip including a long strip-shaped shell 1, a long strip-shaped substrate 2 and a plurality of light beads 3. The substrate 2 is disposed inside the shell 1 and the length extension directions of the two are the same. The substrate 2 is inclinedly disposed inside the shell 1 along the width direction. The plurality of light beads 3 are sequentially spaced on the substrate 2 along the length direction of the substrate 2. At least one side of the substrate 2 is provided with a notch 21. By adopting this design approach, the synergistic effect of the notch 21 on the sidewall of substrate 2 and its arrangement with the housing 1 and LED beads 3 can achieve the following comprehensive benefits: the notch 21 structure preferentially releases local stress during dynamic bending, significantly reducing the mechanical load on the conductive lines and solder joints 22, and improving bending life; at the same time, the matching relationship between the deformation of notch 21 and the LED spacing suppresses chip misalignment and encapsulation glue cracking; the elastic deformation unit formed by notch 21 further avoids plastic damage to substrate 2, and combined with the optimization of heat dissipation channels, it reduces temperature rise and extends the light decay cycle; in addition, the redundant design of notch 21 can isolate the risk of fault propagation, and with the compatibility of lightweight substrate and modular cutting, it achieves a unified technical effect of high reliability, low cost and multi-scenario adaptability, systematically solving the core technical bottleneck of electrical-optical-mechanical multi-physics field coupling failure in dynamic applications of flexible light strips. Furthermore, since the substrate 2 is inclined within the housing 1 along the width direction, when the substrate 2 is laterally bent, the lateral bending stress is decomposed into shear and normal compression components by the tilt angle, allowing adjacent modules to generate elastic displacement to offset the deformation accumulation, thus systematically improving mechanical reliability, electrical stability and optical consistency.
