Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically to a flexible light strip. Background Technology

[0002] Flexible light strips are widely used in decorative lighting, advertising displays, automotive modifications, and home ambiance creation due to their bendable and cutable properties. Existing flexible light strips are typically composed of LED chips soldered onto a flexible printed circuit board (FPC) and covered with a transparent or translucent PVC or silicone sleeve.

[0003] However, traditional flexible LED strips have the following shortcomings: First, their bending performance mainly depends on the physical properties of the FPC substrate itself and the flexibility of the outer sleeve. When three-dimensional twisting or small-radius bending is required, stress easily concentrates at the LED solder joints or circuit traces. Long-term repeated bending can easily lead to solder joint cracking and circuit breakage, affecting service life. Second, most LED strip shells have a flat or simple circular cross-section, and there is a lack of a stable positioning structure between the internal LED strip and the shell. The LED strip is prone to sliding or twisting within the shell, affecting the uniformity of light output and structural reliability. Furthermore, traditional LED strip splicing methods often require welding or the use of additional external connectors, which is cumbersome and not conducive to users quickly extending the length.

[0004] Therefore, there is an urgent need for a new type of flexible light strip that can enhance fatigue resistance from the internal structure, optimize external protection and positioning, and achieve convenient modular splicing. Utility Model Content

[0005] In view of the above, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a flexible light strip.

[0006] A flexible light strip includes a flexible strip-shaped shell and a light-emitting strip embedded in the flexible strip-shaped shell. The light-emitting strip is elongated and has a plurality of light sources spaced apart on it. In the area between two adjacent light sources, a first bending notch and a second bending notch are respectively provided near the two side edges of the light-emitting strip. The portion between the first bending notch and the second bending notch constitutes a twisted portion. The first bending notch is convex and the second bending notch is concave.

[0007] Preferably, the flexible strip shell is cylindrical in shape and made of a transparent or translucent material.

[0008] Preferably, the flexible strip shell includes a spine portion centrally located along its length, and C-shaped outer frames respectively connected to the upper and lower sides of the spine portion; the upper outer frame and the spine portion enclose to form an upper assembly cavity, and the lower outer frame and the spine portion enclose to form a lower assembly cavity.

[0009] Preferably, there are two light strips, which are fixedly installed in the upper assembly cavity and the lower assembly cavity, respectively.

[0010] Preferably, the outer frame on both sides forms an assembly gap that communicates with the upper assembly cavity and / or the lower assembly cavity.

[0011] Preferably, the light source is an LED light source.

[0012] Preferably, it further includes a first docking portion disposed at one end of the flexible strip shell and a second docking portion disposed at the other end.

[0013] Preferably, the first mating part is a male connector, and the second mating part is a female connector that matches the male connector.

[0014] Preferably, the first bending notch and the second bending notch on both sides of the adjacent twisted portion are arranged in opposite directions. Beneficial effects

[0015] Firstly, by designing specific convex first bending notches and concave second bending notches on the light strip, a twisted section that is easy to directionally deform is constructed between adjacent light sources. When the light strip bends, the stress is guided and concentrated and released in these pre-set twisted sections, effectively preventing the LED solder joints and delicate circuits from failing due to repeated stress, fundamentally improving the product's mechanical flexibility and fatigue resistance, and extending its service life.

[0016] Secondly, the cylindrical, flexible strip shell facilitates uniform twisting. Its unique internal ridge and C-shaped outer frame design create stable upper and lower assembly cavities, firmly confining the light strip within and preventing it from sliding or rotating, ensuring consistent and stable light output direction. The transparent or semi-transparent shell allows light to pass through evenly, creating a soft, surface light source effect.

[0017] Thirdly, by integrating a first and second mating part that can be interlocked at both ends of the light strip, a tool-free, quick-connect electrical and mechanical connection is achieved. Users can easily connect multiple light strips end to end to flexibly form the required length, greatly improving the product's practicality and application flexibility. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1 to 3 The embodiment shown provides a flexible light strip designed to improve its bendability and lifespan.

[0022] The flexible light strip mainly includes a flexible strip shell 100, a light-emitting strip 200 embedded therein, and a first docking portion 310 and a second docking portion 320 disposed at both ends of the flexible strip shell 100.

[0023] The flexible strip shell 100 is cylindrical in shape. This structure can evenly withstand torsional forces in all directions, thereby achieving smoother and smaller radius twisting and bending, significantly improving the flexibility of the light strip. The flexible strip shell 100 is made of transparent or semi-transparent material, allowing the light generated by the internal light-emitting strip 200 to pass through evenly and softly, forming a good surface light source effect.

[0024] The flexible strip shell 100 can be made of silicone, transparent PVC or TPU.

[0025] Specifically, the cross-sectional structure of the flexible strip shell 100 is as follows: Figure 2 As shown, it includes a spine portion 110 centrally located along its length. On the upper and lower sides of the spine portion 110, there are approximately C-shaped outer frame frames 120. The upper outer frame frame 120 and the upper part of the spine portion 110 together form an upper assembly cavity 130; similarly, the lower outer frame frame 120 and the lower part of the spine portion 110 together form a lower assembly cavity 140. The ends of the outer frame frames 120 on both sides are not completely closed to the spine portion 110, but rather have an assembly gap 150. This assembly gap 150 communicates with the upper assembly cavity 130 and the lower assembly cavity 140, providing an entry point for the installation of the light strip 200. Workers can insert and fix the light strip into the corresponding assembly cavity through this gap, simplifying the process.

[0026] Two light strips 200 are provided, respectively housed in the upper assembly cavity 130 and the lower assembly cavity 140. The light strips 200 are elongated and have multiple spaced light sources 210 arranged on them. In this embodiment, the light sources 210 are preferably LED beads.

[0027] To achieve the excellent bending and twisting capabilities of the 200mm LED strip, its structure has been specially designed. For example... Figure 3 As shown, in the substrate area between two adjacent light sources 210, near the edges of both sides of the light-emitting strip 200, a first bending notch 221 and a second bending notch 222 are stamped or etched, respectively. The area between these two notches constitutes a deformable twisted portion 230.

[0028] Furthermore, the first bending notch 221 is convex, while the second bending notch 222 is concave. This convex-concave notch pairing design allows the middle twisted portion 230 to naturally form a C-shaped or S-shaped deformation tendency under stress. When the light strip needs to be twisted, stress is concentrated and released in these pre-designed twisted portions 230, avoiding stress concentration at fragile solder joints or wire traces. This greatly enhances the mechanical flexibility and fatigue resistance of the light strip, and improves the overall service life of the flexible light strip.

[0029] like Figure 1 As shown, the first docking portion 310 is fixedly disposed at one end of the flexible strip shell 100, and the second docking portion 320 is fixedly disposed at the other end. The first docking portion 310 and the second docking portion 320 can be matched and connected to each other in terms of physical structure and electrical connection interface. The circuit of the light strip 200 is electrically connected to the first docking portion 310 and the second docking portion 320. Through this design, multiple flexible light strips can be connected end to end: the second docking portion 320 of one light strip is connected to the first docking portion 310 of another light strip, thereby realizing the conduction of power and signal, allowing users to flexibly splice them into longer light strips of any length according to actual usage needs, with extremely strong expandability.

[0030] The first mating part 310 can be designed as a male head with a protruding conductive pin; the second mating part 320 is correspondingly designed as a female head with a conductive socket for accommodating the pin. After mating, a simple rotating locking mechanism can be provided to ensure the stability and waterproofness of the connection.

[0031] The first bending notch 221 and the second bending notch 222 on both sides of the adjacent twisted portion 230 are arranged in opposite directions, so as to meet the convenience of the flexible light strip when it is twisted left and right.

[0032] Summary of beneficial effects: By setting a first bending notch and a second bending notch of a specific shape, this utility model forms a deformable part on the light strip that is easy to twist, thereby improving the mechanical flexibility of the light strip from the root; the cylindrical shell and the unique spine-outer frame cavity design protect the internal light strip and ensure the overall flexibility and ease of assembly; the modular docking part design greatly improves the practicality and scalability of the product.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
