[0010] As an embodiment of the present application, the second visible component is recessed to form a gap groove near the bottom wall of the lamp source assembly, and the groove wall opposite to the lamp source assembly is arc-shaped.

[0011] As an embodiment of the present application, the lamp strip structure further comprises a visible sheet, and the visible sheet is arranged on the lower side of the circuit board at the bottom end of the groove body.

[0012] As an embodiment of the present application, the first visible component and the second visible component are both made of silica gel or PVC material.

[0013] As an embodiment of the present application, the color of the second visible component is milky white and translucent.

[0014] As an embodiment of the present application, the color of the first shell and the second shell is black and non-translucent.

[0015] Compared with the prior art, the lamp strip structure provided by the embodiment of the present application has the following advantages:

[0016] 1.

[0017] 2. In the lamp strip structure provided by the present application, the first visible component with transparent structure provides the user with a direct observation means of the circuit board inside the lamp strip.

[0042] Please combine Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention discloses a light strip structure 1, which includes a first housing 11, a second housing 12, a light source assembly 13, a first visible component 15, and a circuit board 14. The first housing 11 and the second housing 12 are arranged opposite to each other and their bottoms are connected to the two side walls of the first visible component 15, forming a groove 111. The circuit board 14 is disposed at the bottom end of the groove 111, and the light source assembly 13 is disposed on the circuit board 14.

[0043] It is understood that the light strip structure 1 forms a groove 111 by arranging the first housing 11 and the second housing 12 opposite to each other and connecting the two side walls of the first visible component 15 to the bottom of the first housing 11 and the second housing 12 respectively. A circuit board 14 is then placed at the bottom of the groove 111, and the light source assembly 13 is placed on the circuit board 14 within the groove 111. This allows the user to observe the circuitry of the circuit board 14 through the first visible component 15. This not only prevents errors in the cutting position due to the lack of a direct means of observing the circuit board 14, which could lead to short circuits, open circuits, or damage to LED beads, but also facilitates the user in cutting the light strip as needed, simplifying the installation and replacement process. Therefore, the light strip structure 1 provided by this utility model effectively solves the problem of errors in the cutting position when cutting light strips in the prior art.

[0044] Furthermore, the first visible component 15 is a transparent elongated structure, and the two long sidewalls of the first visible component 15 are respectively connected to the first housing 11 and the second housing 12.

[0045] It is understandable that the first visible component 15 is a transparent structure, providing users with a way to intuitively observe the circuit board 14 inside the light strip. This not only makes it convenient for users to cut the light strip as needed, but also makes it convenient for users to check the internal condition of the light strip structure 1 when the light source component 13 malfunctions, and to quickly locate the problem and repair the light strip through the first visible component.

[0046] Furthermore, both the first shell 11 and the second shell 12 are “└” shaped structures.

[0047] Specifically, please combine Figure 2 and Figure 3 As shown, the first housing 11 and the second housing 12, along with the first visible component 15, are all elongated structures. Both the first housing 11 and the second housing 12 have a “└” shaped structure, meaning their cross-sections are “└” shaped. Furthermore, the first housing 11 and the second housing 12 are arranged opposite to each other, forming a cross-section with a “└” or “┘” shape. Finally, by connecting the two long sidewalls of the elongated first visible component 15 to the first housing 11 and the second housing 12 respectively, the first housing 11, the first visible component 15, and the second housing 12 are combined and enclosed to form a structure with a cross-section of “└”, “—”, or “┘”, i.e., “└—┘”, and a groove 111. The circuit board 14 is placed at the bottom of the groove 111, and the lamp source assembly 13 is placed on the circuit board 14 within the groove 111.

[0048] It can be understood that by setting the first shell 11 and the second shell 12 to be connected with the first visible part 15 and form the groove 111 of the lamp source assembly 13 and the circuit board 14 that can load the lamp strip, the overall integration and integration of the structure are realized, not only the internal support stability of the lamp strip structure 1 is enhanced, but also the overall stability and deformation resistance of the lamp strip structure 1 are enhanced, thereby improving the durability of the lamp strip. The circuit board 14 is arranged at the bottom end in the groove 111, and the lamp source assembly 13 is arranged on the circuit board 14. This layout not only reasonably utilizes the space in the groove 111, but also ensures that the lamp source assembly 13 can uniformly distribute light, thereby improving the lighting effect. In addition, the entire lamp strip structure 1 adopts a modular design, and the components are combined together through a simple connection method, so that the installation process is more convenient and fast, and the maintenance and replacement work in the later stage is also more convenient, thereby greatly improving the use effect and user experience of the lamp strip.

[0049] Further, as shown in Figure 3 and Figure 4 , the opposite side walls of the first shell 11 and the second shell 12 and away from the lamp source assembly 13 are provided with grooves 112, and the two opposite grooves 112 form a buckle position. The buckle position is used to clamp the grid (not shown in the figure).

[0050] It should be understood that the grid as a part of the lamp strip structure 1 is a frame made of metal or plastic and the like. The material, color, shape and the like of the grid need to be customized according to different application scenarios and aesthetic needs.

[0051] Specifically, the two opposite grooves 112 form a buckle position for installing the grid. The connection mode of the buckle position is more convenient and fast compared with the traditional screw fixing mode, so that the lamp strip structure 1 only needs to align the buckle part of the grid with the grooves 112 on the first shell 11 and the second shell 12, and then press gently to realize fixation. This installation method not only improves the work efficiency, but also reduces the installation difficulty.

[0052] More specifically, the grid is installed through the buckle position, which has a certain universality and improves the compatibility of the lamp strip structure 1 to the grid. As long as the design of the grid meets the size and shape requirements of the buckle position, it can be easily clamped and fixed on the lamp strip structure 1. This design enables the lamp strip to adapt to grids of different materials, shapes and functions, providing users with more choices and flexibility. Therefore, users can customize grids with specific shapes, colors and materials according to their own preferences and needs, and fix them on the lamp strip structure 1 through the buckle position. This customized design not only improves the individuality of the lamp strip structure 1, but also enhances the user's sense of participation and satisfaction.

[0053] Optionally, in the case of high brightness lighting, the user can choose a grid with a larger opening and higher light transmittance; while in the case of soft lighting, the user can choose a grid with a smaller opening and lower light transmittance. This design makes the lamp strip structure 1 more flexible and diverse, able to meet the needs of different users, promoting the standardization, modularization and customization development of the lamp strip structure 1.

[0054] Specifically, the design of the buckle position can fix the grid between the first shell 11 and the second shell 12, and this fixing method is not only stable and reliable, but also can prevent the grid from loosening or falling off during use, thereby ensuring the overall stability of the lamp strip structure 1.

[0055] Specifically, the buckle position is arranged on the opposite side walls of the first shell 11 and the second shell 12 and away from the light source assembly 13, and the mounting position of the grid is located at the upper part of the light source assembly 13, so that the grid installed on the lamp strip structure 1 can not only effectively isolate the erosion of dust, water vapor and other impurities in the external environment to the light source assembly 13, ensure the cleanliness and dryness of the light source assembly 13, and prolong its service life, but also can prevent the user or other objects from accidentally touching the light source assembly 13, thereby avoiding the occurrence of safety hazards such as electric shock or short circuit.

[0056] Further, the lamp strip structure 1 further comprises a second visible component 16, which is arranged in the groove body 111 and covers the light source assembly 13, and the top wall of the second visible component 16 away from the light source assembly 13 is located on the same horizontal plane as the buckle position.

[0057] Further, the color of the second visible component 16 is milky white and transparent.

[0058] Specifically, the second visible component 16 has light transmittance, which can allow light to pass through its surface and diffuse into the surrounding environment, and is located at the upper part of the light source assembly 13, covering the light source assembly 13. Through the combination with the light source assembly 13, the second visible component 16 can not only effectively control the light diffusion direction and intensity of the light source assembly 13, achieve a more soft and uniform lighting effect, but also can reduce the generation of glare, when the light is emitted from the light source assembly 13 and passes through the second visible component 16, its surface can absorb or reflect part of the light, thereby reducing the degree of glare when the light directly irradiates the eyes.

[0059] Specifically, by the design that the top wall of the second visible component 16 is at the same horizontal plane as the buckle position, a continuous line is visually formed, the integration of the light strip structure 1 in the vertical direction is realized, the light strip structure 1 as a whole looks more unified and coordinated, the integrity and aesthetics of the light strip structure 1 are enhanced, the visual effect of the light strip in various application scenarios is improved, and the light strip is more in line with modern aesthetic requirements. In addition, when the grille is buckled on the buckle position, the second visible component 16 can also provide additional support for the grille, thereby enhancing the stability of the light strip structure 1 in installing the grille and reducing the possibility of the grille loosening or falling off during use.

[0060] Further, referring to Figure 4 As shown in the drawings, the second visible component 16 is recessed near the bottom wall of the light source assembly 13 to form a gap groove 161, and the groove wall 1611 opposite to the light source assembly 13 is arc-shaped.

[0061] Specifically, the gap groove 161 provides a heat isolation space for the light source assembly 13 to reduce the working temperature of the light strip, and also serves as part of a heat dissipation channel. The heat generated by the light source assembly 13 is dissipated to the surrounding environment through the gap groove 161 by heat conduction and convection, thereby improving the heat dissipation efficiency of the light strip and prolonging the service life of the light source assembly 13.

[0062] Specifically, the groove wall 1611 of the gap groove 161 is designed to be arc-shaped, which has a special effect in optics. When the light emitted from the light source assembly 13 is incident on the arc-shaped groove wall 1611, the light will be refracted and reflected. Due to the curvature of the arc, the reflection and refraction paths of the light on the groove wall 1611 will be more complex and diversified, thereby increasing the diffusion angle and range of the light. Moreover, the excessive concentration or absence of light in a particular direction is reduced, so that the light emitted by the light strip structure 1 is softer and more uniform, avoiding the problems of glare or dark areas.

[0063] Further, the light strip structure 1 further comprises a visible sheet 17, which is arranged on the lower side of the circuit board 14 at the bottom end of the groove body 111.

[0064] Specifically, the visible sheet 17 is a PET sheet, which has high flexibility and strength and can be used as a protective plate. In the environment of frequent bending or long-term use of the light strip structure 1, the visible sheet 17 can tightly adhere to the lower side of the circuit board 14 to play a buffering and supporting role, effectively preventing physical damage such as fracture and delamination of the circuit board 14 caused by bending, reducing the light strip failure caused by damage of the circuit board 14, and thereby improving the impact resistance and service life of the light strip.

[0065] Specifically, the visual sheet 17 is made of transparent PET material, which maintains the visibility of the internal structure of the light strip, allowing users to clearly see the layout and connection of the components on the circuit board 14, facilitating troubleshooting and maintenance, and facilitating cutting.

[0066] Further, the first visual component 15 and the second visual component 16 are both made of silicone or PVC material.

[0067] Specifically, the first visual component 15 and the second visual component 16 are both made of silicone or PVC material. First, silicone and PVC material both have good flexibility and elasticity, so that the first visual component 15 and the second visual component 16 can adapt to various bending and twisting shapes in the light strip structure 1 without breaking or deforming, which is particularly important for light strips that need to be frequently bent or installed on complex curved surfaces. Second, silicone and PVC material both have weather resistance and corrosion resistance, so that the first visual component 15 and the second visual component 16 can resist the erosion of ultraviolet light, high temperature, low temperature, humidity and other harsh environments, so that the light strip structure 1 can maintain stable performance in various outdoor or extreme conditions, prolonging the service life. Third, silicone and PVC material are both good insulators, so that the first visual component 15 and the second visual component 16 can effectively isolate the direct contact between the circuit board 14 and the light source assembly 13 and the external environment, reducing the risk of electrical failure, thereby ensuring the safe operation of the light strip. Therefore, the durability and safety of the light strip structure 1 are improved.

[0068] More specifically, silicone and PVC material are both easy to be molded by injection molding, extrusion and other processes, so that the production process of the first visual component 15 and the second visual component 16 is more efficient and flexible. At the same time, silicone and PVC material are also easy to cut, punch and other processing operations, which facilitates the assembly and customization of the light strip structure 1, improving the processing convenience of the light strip structure 1.

[0069] Further, the first shell 11 and the second shell 12 are both black and opaque.

[0070] Specifically, the black first shell 11 and the second shell 12, in combination with other colored visual components or light source assemblies 13, can achieve rich color effects, and the flexibility of design allows the light strip to meet the aesthetic needs of different users, and also promotes the innovation and diversification of the light strip structure 1 product. In addition, the opaque first shell 11 and the second shell 12 can effectively control the propagation path of light, preventing light emitted by the light source assembly from leaking from the non-design area of the light strip structure 1, ensuring that the light can be projected in the predetermined direction and range, improving the efficiency and accuracy of illumination.

[0071] Any combination of the technical features in the above embodiments can be made, and for the sake of brevity, not all possible combinations are described above, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered within the scope of the present disclosure.

[0072] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the scope of the utility model patent. It shall be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
