Description

Technical Field

[0001] This utility model belongs to the field of LED waterproof linear light technology, specifically a flexible and shape-adjustable LED waterproof linear light with a lens. Background Technology

[0002] In the field of architectural lighting, linear LED luminaires are widely used in scenarios such as wall washing, contouring, and edge outlining, requiring close conformity to the architectural shape to achieve curved or irregular shapes. However, existing technologies have many shortcomings:

[0003] Conventional linear rigid strip lights, due to their rigid structure, cannot meet the bending and shaping requirements of curved or irregular architectural surfaces. Even when adapted to different shapes through cutting and splicing, they are prone to creating dark areas and breaks in the light, which not only disrupts the continuity of the light effect but also affects the visual aesthetics of the building during the day. The waterproof structure design of traditional linear lights is rudimentary (such as simple sealant and spliced ​​shells). When used outdoors for a long time, rainwater intrusion and ultraviolet radiation can cause silicone aging and water seepage into the lamp body, resulting in short circuits in the internal circuits and failure of the light source, which severely shortens the life of the lamp. Most flexible linear lights, in pursuit of flexibility, neglect the optimization of heat dissipation structure. The heat generated by the LED light source is difficult to dissipate effectively. Heat accumulation can easily lead to accelerated light decay and color temperature drift, reducing the lighting quality and the reliability of the lamp. Traditional linear lights lack a refined secondary light distribution design or have low integration of light distribution elements and lamp body, resulting in uneven light dispersion, obvious graininess, and prominent glare, which cannot meet the requirements of high-end architectural lighting for "uniform, soft, and glare-free" light effects.

[0004] Therefore, a flexible and shape-adjustable LED waterproof linear lamp with a lens is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a flexible and shape-adjustable LED waterproof linear lamp with a lens, which has the advantages of being flexible and shape-adjustable to fit the curved surface of buildings, having strong waterproof and weather resistance, efficient heat dissipation and stable light efficiency, and uniform and soft optical effects.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flexible and shape-adjustable LED waterproof linear lamp with a lens, comprising an integrally molded silicone lamp body shell, a flexible circuit board embedded in the silicone lamp body shell, LED light sources installed on the flexible circuit board at equal intervals, a secondary light distribution lens configured on the LED light sources, and wires leading out from both ends of the silicone lamp body shell, the wires being electrically connected to the flexible circuit board.

[0007] Preferably, the top end of the secondary light distribution lens penetrates the top surface of the silicone lamp housing, and the bottom end of the secondary light distribution lens is embedded in the silicone lamp housing along with the LED light source.

[0008] Preferably, the outer surface of the secondary light distribution lens is covered with a tempered glass sheet, which is sealed and fixed by adhesive.

[0009] Preferably, a TPU waterproof membrane is provided at the joint between the silicone lamp housing and the secondary light distribution lens.

[0010] Preferably, the outer surface of the silicone lamp housing is coated with a nano-hydrophobic coating.

[0011] Preferably, a metal heat dissipation substrate is embedded at the bottom of the silicone lamp housing, and the metal heat dissipation substrate is connected to the bottom surface of the flexible circuit board through thermally conductive silicone.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model achieves 3D multi-directional bending and shaping capabilities through the collaborative design of flexible circuit boards and integrated silicone lamp bodies. It can perfectly fit the curved surfaces or irregular contours of buildings, completely solving the pain point of traditional rigid strip lights being unable to adapt to complex shapes due to their rigid structure. At the same time, it abandons the splicing installation method and relies on customized length and uninterrupted circuit layout to eliminate dark areas and visual breaks in the light, ensuring continuous and uniform light effect at night while improving the aesthetics of the building's daytime shape. In terms of waterproof and weather-resistant performance, the integrated silicone shell blocks the path of water vapor intrusion from the source, and the TPU waterproof membrane strengthens the joint seal, making it suitable for humid scenarios such as swimming pools and fountains. The nano hydrophobic coating reduces the adhesion of dust and rainwater, and the tempered glass protects the lens from scratches and yellowing. Combined with the UV-resistant properties of silicone, it greatly extends the outdoor service life and significantly reduces the later maintenance costs.

[0014] 2. The metal heat dissipation base embedded at the bottom of the silicone lamp body of this utility model is tightly bonded to the flexible circuit board through thermally conductive silicone, forming an efficient heat conduction path, quickly dissipating the heat generated by the LED, effectively alleviating the problems of light decay and color temperature drift, ensuring long-term stable lighting quality, and improving the reliability of the lamp. In terms of optical effect, the secondary light distribution lens precisely controls the light output angle and uniformity, eliminates the graininess of light, and achieves a soft and glare-free lighting effect, which is suitable for various scenarios such as wall washing and contouring. Moreover, the precise alignment of the secondary light distribution lens with the LED light source and the silicone sealing design avoid optical misalignment and moisture corrosion, and maintain stable light distribution performance over a long period of time.

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides a flexible and shape-adjustable LED waterproof linear lamp with a lens, including an integrally molded silicone lamp body shell 1. The integral molding process ensures waterproof sealing while giving the silicone lamp body shell 1 flexible shape-adjustable characteristics, adapting to curved building surfaces. A flexible circuit board 2 is embedded within the silicone lamp body shell 1, made of flexible material, which can bend synchronously with the silicone lamp body shell 1, ensuring the circuit does not break during the shaping process and achieving 3D multi-directional bending functionality. Equally spaced LED light sources 3 are installed on the flexible circuit board 2, ensuring uniform light emission and avoiding excessively bright or dark areas, thus improving overall light efficiency consistency. A secondary light distribution lens 4 is configured on the LED light source 3 for secondary optical light distribution, optimizing the light output angle, eliminating graininess, and making the light uniform and soft, meeting the lighting needs of various scenarios such as wall washing and contour lighting. Wires 5 extend from both ends of the silicone lamp body shell 1 to achieve electrical connection between the lamp and external circuits, ensuring stable power supply and adapting to series or parallel installation layouts. The wires 5 are electrically connected to the flexible circuit board 2.

[0023] Specifically, the top of the secondary light distribution lens 4 penetrates the top surface of the silicone lamp housing 1, and the bottom of the secondary light distribution lens 4 is embedded in the silicone lamp housing 1 along with the LED light source 3. The top penetration design allows the light to be directly controlled by the lens, avoiding interference from the silicone material on the optical effect. The bottom is embedded inside the silicone lamp housing 1, which not only achieves structural fixation but also ensures waterproof performance through silicone wrapping.

[0024] Furthermore, the outer surface of the secondary light distribution lens 4 is covered with a tempered glass sheet 6, which is sealed and fixed with adhesive. This covers the surface of the secondary light distribution lens 4, enhancing its scratch resistance and yellowing resistance, extending the service life of the optical components. The adhesive seal also strengthens the waterproof performance, preventing moisture from entering from the edge of the secondary light distribution lens 4.

[0025] Furthermore, a TPU waterproof membrane is provided at the joint between the silicone lamp housing 1 and the secondary light distribution lens 4, forming an additional waterproof barrier at the joint, further improving the overall waterproof rating of the lamp and making it suitable for harsh environments such as humid or underwater environments.

[0026] It is worth noting that the outer surface of the silicone lamp housing 1 is coated with a nano-hydrophobic coating, which reduces the adhesion of dust and rainwater to the surface of the silicone lamp housing 1, reduces the frequency of cleaning and maintenance, and enhances the anti-fouling and weather-resistant properties of the silicone lamp housing 1.

[0027] It is worth noting that a metal heat dissipation base 7 is embedded at the bottom of the silicone lamp housing 1. The metal heat dissipation base 7 is connected to the bottom surface of the flexible circuit board 2 through thermally conductive silicone 8. The metal heat dissipation base 7 quickly dissipates the heat generated by the LED, and the thermally conductive silicone 8 fills the air gap, enhances the heat conduction efficiency, alleviates light decay, extends the life of the lamp, and ensures stable lighting performance.

[0028] The LED light source 3 is existing technology and will not be described in detail. In addition, this utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0029] Working principle and process: The external power supply is connected to and transmitted to the flexible circuit board 2 through the wire 5. The current is conducted through the flexible circuit board 2 to the equidistantly arranged LED light sources 3, which are powered on and emit light. The light first enters the secondary light distribution lens 4 for angle adjustment and light uniformization to eliminate graininess. Then it passes through the top of the secondary light distribution lens 4 and is projected outward through the tempered glass sheet 6 to achieve a uniform and soft lighting effect. In this process, the one-piece molded silicone lamp body shell 1, the TPU waterproof membrane at the seam and the nano hydrophobic coating on the outer surface together form a multi-layer waterproof protection to prevent external moisture from entering the internal components. At the same time, the heat generated by the LED light source 3 is transferred to the thermally conductive silicone 8 through the bottom surface of the flexible circuit board 2, and then efficiently conducted to the metal heat dissipation base 7 by the thermally conductive silicone 8, avoiding heat accumulation that leads to light decay and ensuring long-term stable operation of the lamp. The flexibility of the flexible circuit board 2 and the silicone lamp body shell 1 ensures that the lamp can maintain the continuity of the above working process even when it is bent and shaped.
