Description

Technical Field

[0001] This utility model belongs to the field of decorative light strip technology and relates to an aluminum-based heat dissipation PCB board LED decorative light strip structure. Background Technology

[0002] LED decorative light strips are widely used in various decorative scenarios due to their advantages such as low energy consumption, high luminous efficiency, and rich colors. Currently, most LED decorative light strips on the market use copper foil as the PCB substrate. However, copper foil has poor heat dissipation performance, and the heat generated by the LED beads during long-term operation cannot be dissipated in time, which can easily lead to accelerated light decay, shortened lifespan, and even circuit failures. Meanwhile, the existing production and assembly process of LED decorative light strips lacks a structured design adapted to the production process: on the one hand, the installation of the substrate and decorative components lacks a precise positioning structure, resulting in low assembly efficiency; on the other hand, the color compatibility of the decorative components is poor, making it difficult to flexibly adjust the appearance color according to actual needs. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing an aluminum-based heat dissipation PCB board LED decorative light strip structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An aluminum-based heat-dissipating PCB board LED decorative light strip structure includes an aluminum-based heat-dissipating PCB board body, a conductive plug, an acrylic mounting base, and a colored silicone decorative strip, which are assembled sequentially. The aluminum-based heat-dissipating PCB board body has several LED beads and current-limiting resistors fixed to its surface using SMT (Surface Mount Technology). The conductive plug is fixed to the electrode leads of the aluminum-based heat-dissipating PCB board body using a soldering process to achieve electrical connection between the light strip and an external power supply. The edges of the aluminum-based heat-dissipating PCB board body are trimmed to fit the dimensions of the acrylic mounting base, removing excess borders to ensure the substrate's shape matches the mounting groove of the acrylic mounting base. The edges of the aluminum-based heat-dissipating PCB board body have a positioning structure. The acrylic mounting base is engraved with a patterned groove matching the shape of the aluminum-based heat-dissipating PCB board body using a carving machine. The aluminum-based heat-dissipating PCB board body is fixed within the patterned groove by the positioning structure. The patterned groove is used for precise embedding of the aluminum-based heat-dissipating PCB board body, achieving substrate positioning and fixation. The colored silicone decorative strip is fixedly installed outside the patterned groove.

[0005] In the above-mentioned aluminum-based heat dissipation PCB board LED decorative light strip structure, the positioning structure includes a snap-fit ​​part, which is uniformly fixed on both sides of the aluminum-based heat dissipation PCB board body. The two side walls of the pattern groove are provided with uniformly distributed snap teeth, and the aluminum-based heat dissipation PCB board body is fixed on the snap teeth in the pattern groove through the snap-fit ​​part.

[0006] In the above-mentioned aluminum-based heat dissipation PCB board LED decorative light strip structure, a support component is fixedly provided at the bottom of the pattern groove, and the top of the support component abuts against the bottom of the aluminum-based heat dissipation PCB board body.

[0007] In the above-mentioned aluminum-based heat dissipation PCB board LED decorative light strip structure, the substrate of the aluminum-based heat dissipation PCB board body is an aluminum substrate with a thickness of 1.0 to 2.0 mm, and the surface of the aluminum-based heat dissipation PCB board body is provided with heat dissipation holes.

[0008] In the above-mentioned aluminum-based heat dissipation PCB board LED decorative light strip structure, the LED beads are preferably SMD2835 models, and the current limiting resistor is selected according to the LED bead parameters.

[0009] In the above-mentioned aluminum-based heat dissipation PCB board LED decorative light strip structure, the acrylic mounting base is made of transparent acrylic sheet with a thickness of 2.5 to 3.5 mm, and the groove depth of the pattern groove is 1.0 to 1.5 mm.

[0010] In the aforementioned aluminum-based heat dissipation PCB board LED decorative light strip structure, the colored silicone decorative strip is made of flexible silicone material and has a U-shaped cross-section.

[0011] In the above-mentioned aluminum-based heat dissipation PCB board LED decorative light strip structure, the bottom two sides of the colored silicone decorative strip are symmetrically fixed with connecting protrusions.

[0012] In the above-mentioned aluminum-based heat dissipation PCB board LED decorative light strip structure, the inner wall of the opening of the pattern groove is provided with connecting grooves on both sides, and the connecting protrusion is engaged in the connecting groove.

[0013] In the aforementioned aluminum-based heat dissipation PCB board LED decorative light strip structure, the colored silicone decorative strip is red, blue, white, or yellow, and can be easily disassembled and replaced to meet the decorative color requirements of different scenarios.

[0014] Compared with existing technologies, the advantages of this utility model are: 1. This utility model has excellent heat dissipation performance. By using an aluminum-based heat dissipation PCB board body instead of a traditional copper foil board, the thermal conductivity of the aluminum base layer is much higher than that of the copper foil board. It can quickly dissipate the heat generated by the LED beads when they are working, effectively reduce the light decay rate of the beads, and extend the service life of the light strip.

[0015] 2. This utility model features highly efficient assembly characteristics. The aluminum-based heat dissipation PCB board body and the acrylic mounting base achieve precise fit through a positioning structure, significantly improving assembly efficiency during the production process. Simultaneously, the patterned groove design of the acrylic mounting base not only enhances structural stability but also provides reliable fixed support for the aluminum-based heat dissipation PCB board body, avoiding loosening problems caused by external vibration or impact.

[0016] 3. By selecting silicone decorative strips of different colors, users can quickly adjust the appearance of the light strip according to the actual decorative style, greatly improving the product's adaptability and aesthetics. The snap-fit ​​design between the connecting protrusion and the connecting groove further enhances the stability of the decorative strip, making it less likely to fall off during use and ensuring the reliability of the overall structure of the light strip.

[0017] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figure 1-4As shown, an aluminum-based heat-dissipating PCB board LED decorative light strip structure includes an aluminum-based heat-dissipating PCB board body 1, a conductive plug 2, an acrylic mounting base 3, and a colored silicone decorative strip 6, which are assembled sequentially. Several LED beads 10 and current-limiting resistors 11 are fixed to the surface of the aluminum-based heat-dissipating PCB board body 1 using SMT surface mount technology. The conductive plug 2 is fixed to the electrode lead-out end of the aluminum-based heat-dissipating PCB board body 1 by soldering, for realizing the electrical connection between the light strip and an external power supply. The edges of the aluminum-based heat-dissipating PCB board body 1 are adjusted according to the dimensions of the acrylic mounting base 3. To meet size requirements, excess borders are removed using a cutting device to ensure the substrate shape matches the mounting groove of the acrylic mounting base 3. The edge of the aluminum-based heat dissipation PCB body 1 is provided with a positioning structure 7. The acrylic mounting base 3 is processed by a carving machine to form a patterned groove 8 that matches the shape of the aluminum-based heat dissipation PCB body 1. The aluminum-based heat dissipation PCB body 1 is fixed in the patterned groove 8 by the positioning structure 7. The patterned groove 8 is used to precisely embed the aluminum-based heat dissipation PCB body 1, realizing the positioning and fixation of the substrate. The colored silicone decorative strip 6 is fixedly installed on the outside of the patterned groove 8.

[0025] Furthermore, the positioning structure 7 includes a snap-fit ​​part 9, which is uniformly fixed to both sides of the aluminum-based heat dissipation PCB board body 1. The two side walls of the pattern groove 8 are provided with uniformly distributed snap teeth 12, and the aluminum-based heat dissipation PCB board body 1 is fixed to the snap teeth 12 in the pattern groove 8 through the snap-fit ​​part 9.

[0026] In this embodiment, the snap-fit ​​part 9 is made of an elastic material, which can undergo slight deformation under external force, facilitating a tight fit with the snap-fit ​​teeth 12, thereby enhancing the stability of the aluminum-based heat dissipation PCB board body 1 within the patterned groove 8. Simultaneously, the spacing of the snap-fit ​​teeth 12 ensures that the snap-fit ​​part 9 can be quickly positioned and firmly fixed during installation, preventing loosening due to external force or vibration. Furthermore, the design of the snap-fit ​​part 9 and snap-fit ​​teeth 12 simplifies the installation process, significantly improving production efficiency and maintenance convenience.

[0027] Furthermore, a support member 13 is fixedly provided at the bottom of the pattern groove 8, and the top of the support member 13 abuts against the bottom of the aluminum-based heat dissipation PCB board body 1.

[0028] In this embodiment, the support component 13 is made of a high thermal conductivity material, which can effectively improve the heat dissipation performance of the aluminum-based heat dissipation PCB board body 1. At the same time, the height of the support component 13 ensures that the aluminum-based heat dissipation PCB board body 1 remains flush with the upper edge of the pattern groove 8 after installation, thereby ensuring the aesthetics of the overall structure.

[0029] Furthermore, the substrate of the aluminum-based heat dissipation PCB board body 1 is an aluminum substrate with a thickness of 1.0 to 2.0 mm, and heat dissipation holes 14 are provided on the surface of the aluminum-based heat dissipation PCB board body 1.

[0030] In this embodiment, the layout of the heat dissipation holes 14 can maximize airflow efficiency, thereby further improving heat dissipation performance.

[0031] Furthermore, the LED bead 10 is preferably of the SMD2835 model, and the current limiting resistor 11 is selected and matched according to the parameters of the LED bead 10.

[0032] In this embodiment, the selection of LED beads 10 not only ensures high brightness and low power consumption, but also provides excellent luminous efficacy and a long service life. The matching design of the current-limiting resistor 11 further optimizes the stability of the circuit, effectively avoiding damage to the LED beads caused by current fluctuations, thereby improving the overall reliability and safety of the light strip.

[0033] Furthermore, the acrylic mounting base 3 is made of transparent acrylic sheet with a thickness of 2.5 to 3.5 mm, and the groove depth of the patterned groove 8 is 1.0 to 1.5 mm.

[0034] In this embodiment, the groove depth of the patterned groove 8 not only facilitates the embedding of the aluminum-based heat dissipation PCB board body 1, but also effectively reduces light scattering, improves the uniformity and concentration of illumination, thereby enhancing the visual effect of the decorative light strip.

[0035] Furthermore, the colored silicone decorative strip 6 is made of flexible silicone material and has a U-shaped cross-section.

[0036] In this embodiment, the flexible material of the colored silicone decorative strip 6 gives it excellent bending performance, enabling it to adapt to various installation environments. Its U-shaped cross-section design not only enhances the structural strength of the decorative strip but also provides better protection, effectively preventing the intrusion of external dust and moisture.

[0037] Furthermore, the bottom sides of the colored silicone decorative strip 6 are symmetrically fixed with connecting protrusions 4, and the inner walls of the opening of the pattern groove 8 are provided with connecting grooves 5, and the connecting protrusions 4 are engaged in the connecting grooves 5.

[0038] In this embodiment, the snap-fit ​​design between the connecting protrusion 4 and the connecting groove 5 not only achieves a stable connection between the colored silicone decorative strip 6 and the patterned groove 8, but also facilitates installation and disassembly, improving ease of use. This structural design effectively prevents the decorative strip from loosening or falling off due to external forces during use, thereby further enhancing the overall stability of the decorative light strip.

[0039] Furthermore, the colored silicone decorative strip 6 can be selected in different colors such as red, blue, white, and yellow as needed, and can be easily disassembled and replaced to meet the decorative color requirements of different scenarios.

[0040] The working principle of this utility model is as follows: In use, the aluminum-based heat-dissipating PCB board body 1 is connected to an external power source via the conductive plug 2. The current, after being regulated by the current-limiting resistor 11, is delivered to the LED beads 10, causing them to emit light. The heat dissipation holes 14 and the support component 13 of the aluminum-based heat-dissipating PCB board body 1 work together to quickly conduct the heat generated by the LED beads 10 during operation to the acrylic mounting base 3 and dissipate it into the surrounding environment, thereby effectively reducing the operating temperature of the light strip and extending its service life. The positioning structure 7 ensures the stability of the aluminum-based heat-dissipating PCB board body 1 within the acrylic mounting base 3, while the engagement of the snap-fit ​​part 9 and the snap-fit ​​teeth 12 simplifies the assembly process. The support component 13 at the bottom of the patterned groove 8 not only provides support but also assists in heat dissipation, further improving the performance stability of the light strip. The colored silicone decorative strip 6 provides protection while enhancing the decorative effect of the light strip through different color selections. The light is evenly distributed through the patterned groove 8 of the acrylic mounting base 3, further enhancing the aesthetics and visual appeal of the illumination.
