Description

Technical Field

[0001] This utility model relates to the field of circuit board waterproofing technology, and in particular discloses a nano-waterproof light strip. Background Technology

[0002] Existing LED light strips are widely used in various indoor and outdoor scenarios, such as advertising light boxes, architectural decoration, and landscape lighting. Especially in outdoor environments, LED light strips need to withstand various harsh weather conditions, particularly the erosion of moisture and rain. Therefore, to extend the lifespan of LED light strips and improve their stability, a waterproof layer is usually added to the surface of the light strip to prevent moisture from entering the circuit board and other critical components, causing short circuits, corrosion, and other damage. However, traditional waterproof structures have the following shortcomings: traditional waterproof layers are usually thick, covering the surface of the light strip, which may affect the light transmittance and brightness of the LED light source; common waterproof materials have weak moisture barrier effects, and over time, moisture may still penetrate into the circuit board or light source module, affecting the performance of the LED light strip. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a nano-waterproof light strip to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides a nano-waterproof light strip, comprising a light strip body, which includes a circuit board, a power drive module and a light source module mounted on the circuit board. An external power source supplies power to the light source module via the power drive module. The light strip also includes a nano-waterproof membrane, which has a nanoparticle layer deposited on the outer surface of the light strip body. The nanoparticle layer of the nano-waterproof membrane is used to prevent external moisture from entering the interior of the light strip body and causing short circuit damage.

[0005] Furthermore, the thickness of the nano-waterproof membrane is 0.1-100μm.

[0006] Furthermore, the nano-waterproof membrane also includes a hydrophobic layer, which is deposited on the outside of the nanoparticle layer. The hydrophobic layer is used to reduce the adhesion of external water droplets to the light strip body.

[0007] Furthermore, the main body of the light strip also includes a control module mounted on a circuit board. The control module includes an RGB controller and an interactive control unit. The RGB controller is electrically connected to the power drive module and the light source module. An external smart mobile terminal controls the parameters of the light source module's color, brightness, color temperature, and dynamic effects via the interactive control unit by regulating the RGB controller.

[0008] Furthermore, the hydrophobic layer is formed by depositing aluminum fluoride or sodium fluoride on the outer surface of the nanoparticle layer, and multiple concave and convex structures are formed on the surface of the hydrophobic layer. The concave and convex structures are used to increase the surface roughness of the hydrophobic layer, thereby increasing the contact angle between external water droplets and the surface of the lamp strip body.

[0009] Furthermore, the nanoparticle layer includes one or more combinations of phenelzine, silica particles, titanium dioxide particles, silicon carbide particles, and polytetrafluoroethylene.

[0010] Furthermore, a sealing shell is fitted on the outside of the circuit board, the inside of the sealing shell is hollow, and a transparent light-transmitting cover is provided on the side of the sealing shell near the light source module.

[0011] Furthermore, the nanoparticle layer is deposited on the outer surface of the light strip body by means of evaporation coating, sputtering coating, ion coating or vapor deposition.

[0012] Furthermore, a heat sink is also provided on the circuit board, and the heat sink is located on the side of the circuit board away from the light source module.

[0013] Furthermore, the circuit board is also provided with a connector, a circuit layer connected to the connector, and a control switch module. The circuit layer is electrically connected to the light source module and the power drive module. An external power source is connected to the power drive module via the connector. The power drive module is used to convert the AC power from the external power source into DC power to supply to the light source module. The control switch module is used to regulate the start and stop of the light source module.

[0014] The technical principle of this utility model is as follows: This solution proposes a nano-waterproof light strip, including a light strip body, which includes a circuit board, a power drive module, and a light source module mounted on the circuit board. A nano-waterproof membrane is disposed on the outer surface of the light strip body. The nano-waterproof membrane comprises a nanoparticle layer and a hydrophobic layer. The nanoparticle layer is formed through evaporation deposition, sputtering deposition, ion deposition, or electrochemical deposition processes, and the materials include silicon dioxide and titanium dioxide particles.

[0015] The beneficial effects of this invention are as follows: The nanoparticle layer and hydrophobic layer effectively prevent water vapor and droplets from entering the interior of the light strip, preventing damage to the circuit and light source module and improving waterproofing. The waterproof membrane thickness is only 0.1-100μm, maintaining waterproofing without affecting the light strip's luminous efficiency. The nanofilm can resist harsh environments such as ultraviolet rays, high temperatures, and humidity, extending its service life. Optimized structure and materials improve heat dissipation, preventing overheating damage to the LED light source.

Detailed Implementation

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0025] Please see Figures 1 to 6As shown, this utility model discloses a nano-waterproof LED strip, comprising a strip body 1, which includes a circuit board 2, a power drive module 3 consisting of a voltage regulator IC and MOSFETs mounted on the circuit board 2, and a light source module 4. An external power supply powers the light source module 4 via the power drive module 3, which converts the input 12V DC power into the voltage and current required by the LEDs. The light source module 4 uses high-brightness 5050 SMD RGB LEDs, with each LED spaced 1 cm apart. It also includes a nano-waterproof membrane 6, which completely covers the outer sides of the circuit board 2, the power drive module 3, and the light source module 4. The nano-waterproof membrane 6 has a nanoparticle layer deposited on the outer surface of the strip body 1. The nanoparticle layer 61 is formed by depositing nanoparticles such as polytetrafluoroethylene and polyurethane on the outer surface of the strip body 1. The nano-waterproof membrane 6 prevents external moisture from entering the strip body 1 and causing damage. This design effectively prevents moisture intrusion, protects the circuit board 2 and the LED light source, is suitable for outdoor and humid environments, and extends the lifespan of the LED strip.

[0026] In this specific embodiment, the nano-waterproof membrane 6 is designed to be 20 μm thick and is uniformly deposited on the surface of the lamp strip body 1 using nano-sized silica particles through sputtering deposition technology. This deposition process is carried out in a vacuum environment to ensure a uniform and bubble-free coating. This thickness of the nano-waterproof membrane 6 effectively balances waterproof performance and light transmittance, ensuring that the brightness and color of the light source output are not significantly affected, while also possessing sufficient mechanical strength to resist external physical impacts.

[0027] Specifically, an additional hydrophobic layer 62, made of aluminum fluoride and approximately 5 μm thick, is added to the outside of the nanoparticle layer 61 using chemical vapor deposition (CVD) technology. This hydrophobic layer 62 effectively reduces the residence time of water droplets on the surface of the light strip by increasing the contact angle between the water droplets and the surface of the light strip (exceeding 150 degrees). The added hydrophobic layer 62 significantly improves the waterproof performance of the light strip when used outdoors, reducing the risk of damage caused by rainwater accumulation. At the same time, this structure also helps reduce the adhesion of dust and contaminants, facilitating cleaning and maintenance.

[0028] Specifically, the main body 1 of the light strip also includes a control module 5 mounted on the circuit board 2. The control module 5 integrates a Wi-Fi-based interactive control unit 52, allowing users to remotely control the light strip's on / off state, color, brightness, and dynamic effects via a smartphone app. The RGB controller 51 uses a common three-in-one LED driver chip and is connected to the power driver module 3 via copper foil, ensuring stable signal transmission. This design gives the light strip smart home compatibility, allowing users to adjust the lighting effects according to different occasions and moods, enhancing the product's user experience.

[0029] The nano-waterproof membrane 6 completely covers the outer side of the circuit board 2, the outer side of the power drive module 3, the outer side of the light source module 4, and the outer side of the control module 5. Furthermore, the solder pins of each module are soldered to the pads on the circuit board 2, and the nano-waterproof membrane 6 simultaneously covers the outer side of both the solder pins and the pads, ensuring that the solder pins and pads are also insulated from the outside environment.

[0030] Specifically, the hydrophobic layer 62 is formed on the outer surface of the nanoparticle layer 61 by depositing aluminum fluoride or sodium fluoride. Multiple uneven structures 621 are formed on the surface of the hydrophobic layer 62, and these structures 621 are formed using nano-etching technology. First, micron-level undulations are created on the surface of the hydrophobic layer 62 using laser etching or nanoimprinting processes. Specific structures include tiny points and depressions, which increase the surface roughness of the hydrophobic layer 62. This increased roughness significantly improves the contact angle of water droplets on the surface of the light strip, reaching over 150 degrees, allowing water droplets to slide off quickly without remaining on the surface.

[0031] This design significantly improves the hydrophobicity of the LED strip surface, making it difficult for water droplets and other liquid contaminants to accumulate. The increased contact angle between the water droplet and the surface enhances waterproofing, effectively protecting the LED strip from external water sources and reducing circuit malfunctions and performance degradation caused by moisture penetration. Furthermore, the surface texture 621 improves the stability of luminous efficacy, preventing light spots and uneven light distribution caused by water droplet accumulation.

[0032] Specifically, the nanoparticles include one or more combinations of phenelzine, silica particles, titanium dioxide particles, silicon carbide particles, and polytetrafluoroethylene. In this embodiment, phenelzine nanoparticles are selected and coated onto the surface of circuit board 2 via vapor deposition. They possess excellent optical properties and chemical stability, effectively blocking moisture and contaminants. This nanocoating technology not only enhances waterproof and dustproof performance but also, due to the photocatalytic properties of titanium dioxide, endows the light strip with a self-cleaning function, reducing maintenance requirements.

[0033] Specifically, the circuit board 2 is covered by a transparent polycarbonate (PC) housing 7, with a semi-transparent light-transmitting cover 71 located on one side of the housing near the light source module 4. The interior space of the housing 7 is sufficient to accommodate all electronic components, while the cover provides both protection and high light transmittance, ensuring unobstructed luminous efficacy and color transmission. The housing 7 provides physical protection for the LED strip's electronic components, preventing dust and moisture, while ensuring uniform and aesthetically pleasing light output. The semi-transparent design of the light-transmitting cover 71 also softens the light and reduces glare.

[0034] Specifically, the nanoparticle layer 61 is deposited on the outer surface of the lamp strip body 1 via evaporation deposition, sputtering deposition, ion deposition, or electrochemical deposition. In this embodiment, an electrochemical deposition technique is used to deposit a uniform and fine nanoparticle layer 61 on the outer surface of the lamp strip body 1. The selected nanoparticles include silicon dioxide and titanium dioxide, which have excellent optical properties and chemical stability, and can effectively block moisture and pollutants. In actual manufacturing, the corresponding deposition method can be selected according to different requirements.

[0035] Specifically, an aluminum-based heat sink 8 is added to circuit board 2, positioned between the power drive module 3 and the light source module 4. The heat sink 8 helps disperse the heat generated by the LED light source module 4 through physical contact, preventing heat concentration that could lead to overheating of circuit board 2 and its components. The heat sink 8 is designed for a tight fit with circuit board 2 to maximize heat transfer efficiency. This design effectively reduces the degradation of light source performance and shortens lifespan caused by temperature increases, ensuring the stability and reliability of the light strip during long-term use.

[0036] Specifically, circuit board 2 also includes a connector 21 and a control switch module 23 connected to the connector 21. The connector 21 is used to connect to an external power source and is connected to the power drive module 3 via wires to ensure stable power input. Circuit board 2 also features multiple circuit layers 22 for efficient transmission of electronic signals, ensuring reliable electrical connections between the light source module 4 and the control module 5. The external power source is connected to the power drive module 3 via connector 21. The power drive module 3 converts the AC power from the external power source into DC power to supply the light source module 4. The control switch module 23 is used to regulate the start and stop of the light source module 4.

[0037] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
