[0030] See also Figures 1 to 5 In the specific embodiment shown, the utility model discloses a waterproof lamp structure, including: an upper shell 10, a lower shell 20 and a wire 30, the upper shell 10 and the lower shell 20 form a accommodating cavity, and the accommodating cavity is installed with a PCB light board 40, and notches 21 are opened on both sides of the accommodating cavity, and a mounting portion 22 extends outward, and the mounting portion 22 is provided with a transverse elastic strip 23. The wire 30 passes through the notch 21 along the mounting portion 22 and is electrically connected to the PCB light board 40, and the wire 30 abuts against the transverse elastic strip 23.

[0031] Specifically, by opening notches 21 on both sides of the accommodating cavity and providing mounting portions 22 and transverse elastic strips 23, when the wire 30 passes through the notch 21 and is electrically connected to the PCB lamp board 40, it will be squeezed and deformed by the transverse elastic strips 23. This design can utilize the elastic force of the elastic strip and the squeezing of the wire 30 to form a tight waterproof seal, preventing moisture from penetrating into the interior from the connection between the wire 30 and the shell, thereby significantly improving the waterproof level of the lamp and having strong practicality. In addition, by forming an accommodating cavity between the upper shell 10 and the lower shell 20, the internal electronic components such as the PCB lamp board 40 can be effectively protected from external moisture, dust and other harmful substances, which is crucial for ensuring the stable operation of the lamp and extending its service life. In addition, since the waterproof lamp structure has good waterproof performance, it can be used in various humid, watery and other harsh environments. This not only expands the application range of the lamp, but also improves its reliability and durability, allowing the lamp to maintain a stable lighting effect in various environments.

[0032] In one embodiment, the transverse elastic strip 23 is disposed on the mounting portion 22 in a wave shape.

[0033] Specifically, the arrangement direction of the transverse elastic strip 23 and the arrangement direction of the wire 30 are in a cross shape. The wavy design increases the contact area between the transverse elastic strip 23 and the wire 30 compared to a flat design. This increase not only improves the extensiveness of physical contact, but also achieves a close fit between the wire 30 and the elastic strip at multiple points through the undulating shape of the wave. This close contact helps to reduce the gap between the wire 30 and the elastic strip, thereby improving the overall connection stability and firmness. In addition, the design of the wavy transverse elastic strip 23 also enhances its fixing effect on the wire 30. Due to the existence of the wavy shape, when the wire 30 is placed on the elastic strip, it will be subjected to extrusion forces from multiple directions of the wave peaks and valleys. This extrusion force helps to firmly fix the wire 30 on the elastic strip; at the same time, the wavy design also improves the anti-slip ability of the wire 30 on the elastic strip. Even when subjected to external forces, the wire 30 is not easy to slide off or shift from the elastic strip. Furthermore, the wavy transverse elastic strips 23 optimize stress distribution between the wires 30 and the strips. When subjected to stress, the wavy strips more effectively disperse stress, preventing damage caused by stress concentration. This stress-dispersing capability not only improves the overall structure's load-bearing capacity but also extends the service life of the strips and wires 30. Furthermore, the wavy design increases the strips' elastic deformation capacity, enabling them to better adapt to minor deformations of the wires 30 under stress, further enhancing durability.

[0034] In one embodiment, the transverse elastic strip 23 is circular, triangular or diamond-shaped.

[0035] Specifically, the circular, triangular or diamond-shaped transverse elastic strip 23, due to its unique geometric shape, can better fit tightly with the surface of the wire 30. This tight fit helps to reduce the gap between the wire 30 and the elastic strip, thereby improving the overall sealing performance. In addition, elastic strips of these shapes usually have good elastic deformation ability and can undergo moderate deformation when subjected to external forces, thereby better adapting to the shape and size changes of the wire 30. This deformation ability helps to maintain continuous close contact between the wire 30 and the elastic strip, further enhancing the sealing effect. In addition, the circular, triangular or diamond-shaped transverse elastic strip 23, due to its irregular shape, can increase the friction of the wire 30 on the elastic strip, thereby improving the anti-slip ability of the wire 30. This anti-slip ability helps to ensure that the wire 30 will not fall off or shift due to external forces during long-term use. Preferably, the transverse elastic strip 23 is circular.

[0036] In one embodiment, the height of the transverse elastic strip 23 is 0.05 mm-0.3 mm.

[0037] Specifically, the height of the transverse elastic strip 23 is within the range of 0.05mm-0.3mm, ensuring close contact between it and the wire 30. This close contact helps reduce the gap between the wire 30 and the elastic strip, preventing moisture or other harmful substances from penetrating the interior of the waterproof lamp structure through the gap. Therefore, this height design is crucial to maintaining the sealing performance of the waterproof lamp structure. Furthermore, within the height range of 0.05mm-0.3mm, the transverse elastic strip 23 maintains good elastic deformation capability. This means that when the wire 30 is placed on the elastic strip, the elastic strip can undergo appropriate deformation to adapt to the shape and size of the wire 30. This deformation capability not only helps maintain close contact between the wire 30 and the elastic strip, but also disperses stress when subjected to force, preventing damage caused by stress concentration. Furthermore, the height range of 0.05mm-0.3mm allows the transverse elastic strip 23 to accommodate wires 30 of different specifications. This means that when designing and manufacturing waterproof lamp structures, elastic strips of different heights can be selected to meet the needs of different wires 30. This flexibility helps reduce production costs and improve production efficiency.

[0038] In one embodiment, the transverse elastic strip 23 and the mounting portion 22 are integrally formed.

[0039] Specifically, the integrated design eliminates any gaps or connectors between the transverse elastic strip 23 and the mounting portion 22. This seamless connection not only enhances the overall strength of the structure but also its stability. When subjected to stress, the integrated structure effectively disperses stress, preventing damage caused by stress concentration, thereby extending the lifespan of the waterproof lamp structure. Furthermore, because the transverse elastic strip 23 and the mounting portion 22 are integrally formed, the connection between them is more tightly secured, eliminating gaps that could result from poor bonding. This tight connection helps reduce the infiltration of moisture or other harmful substances, improving the waterproof lamp structure's sealing performance. This sealing performance is particularly important in humid or harsh environments, ensuring the proper operation and longevity of the waterproof lamp structure.

[0040] In one embodiment, see Figure 4 and Figure 5 As shown, both the upper shell 10 and the lower shell 20 are provided with the notch 21 and the mounting portion 22 .

[0041] Specifically, by providing notches 21 and mounting portions 22 on both the upper shell 10 and the lower shell 20, the wire 30 can be in close contact with the transverse elastic strip 23 at both ends. This double-end contact method can more effectively squeeze the outer skin of the wire 30, causing it to deform and fit tightly to the elastic strip. This tight fit helps to reduce the gap between the wire 30 and the shell, preventing moisture or other harmful substances from penetrating into the waterproof structure through the gap, thereby significantly improving the waterproof sealing effect. In addition, since the wire 30 is squeezed and fixed by the transverse elastic strip 23 at both ends, this technology can enhance the reliability of the waterproof structure. During long-term use, even if the wire 30 undergoes slight deformation due to force or temperature changes, due to the presence of double-end fixation, it can maintain close contact with the elastic strip, thereby ensuring the continued stability of the waterproof performance. In addition, since the wire 30 is squeezed and fixed by the transverse elastic strip 23 at both ends, this technology can reduce the loosening and wear of the wire 30 during long-term use. This effect of reducing loosening and wear helps to improve the durability of the waterproof structure and extend its service life.

[0042] In one embodiment, the upper shell 10 is further provided with a lens 11 .

[0043] Specifically, the PCB light board 40 utilizes existing publicly available technology, which will not be elaborated upon here. Specifically, the lens 11 precisely controls the direction and angle of light propagation, ensuring that the light is emitted along a predetermined path. This control allows the light to be more concentrated and efficiently illuminate the target area, thereby improving the efficiency of light emission. Furthermore, by rationally designing the shape and size of the lens 11, the angle and range of light diffusion can be adjusted. This adjustment allows the light to illuminate a wider area, thereby expanding the illumination range. In scenes requiring large-area illumination, this function of the lens 11 can significantly improve the lighting effect.

[0044] In one embodiment, the lens 11 is hemispherical.

[0045] Specifically, hemispherical lens 11 can focus light parallel to the centerline of lens 11 onto a single point, known as the focal point. This characteristic is known as the focusing effect of lens 11. Leveraging this effect, hemispherical lens 11 can magnify light, allowing it to more concentratedly illuminate the target area after passing through lens 11, thereby enhancing the brightness and lighting effect. Furthermore, when light passes through hemispherical lens 11, it refracts due to the difference in refractive index between lens 11 and the surrounding medium. By rationally designing the shape and size of lens 11, the angle and direction of refraction can be controlled, allowing the light to propagate along a predetermined path. This directional control is particularly important in lighting equipment, ensuring that light accurately illuminates the area requiring illumination.

[0046] In one embodiment, the lens 11 is convex hemispherical or concave hemispherical.

[0047] Specifically, the convex hemisphere is used for focusing light, and the concave hemisphere is used for astigmatism. Among them, the convex hemisphere lens 11 has the characteristic of focusing parallel light rays on one point. When light rays pass through the convex hemisphere lens 11, they will be focused and refracted toward the center point of the lens 11, and form a clear focus on the other side of the lens 11. This characteristic makes the convex hemisphere lens 11 very useful in scenes that require high-intensity, small-range lighting. In addition, since the convex hemisphere lens 11 can focus light rays on one point, it can significantly improve the utilization rate of light rays. When the intensity of the light source is limited, the use of the convex hemisphere lens 11 can ensure that more light rays are effectively utilized for lighting. Among them, in contrast to the convex hemisphere lens 11, the concave hemisphere lens 11 has the characteristic of diverging light rays. When light rays pass through the concave hemisphere lens 11, they will be refracted toward the edge of the lens 11 and form divergent light rays. This characteristic makes the concave hemisphere lens 11 very useful in scenes that require large-scale, low-intensity lighting. In addition, the astigmatism of the concave hemispherical lens 11 can expand the lighting range, so that the light can be more evenly distributed throughout the lighting area. This feature is particularly important in scenes that require large-area lighting, such as home lighting, office lighting, etc.

[0048] In one embodiment, the lens 11 and the upper shell 10 are integrally formed.

[0049] Specifically, when the lens 11 and the upper shell 10 adopt an integrally formed structure, the connection between them will be more firm and stable. This structural form can effectively reduce loosening or damage caused by long-term use or external environmental factors (such as vibration, impact, etc.), thereby improving the structural strength and stability of the entire product. In addition, the integrally formed structure helps to reduce the gap and air layer between the lens 11 and the upper shell 10, thereby reducing the refraction and reflection losses of light during the propagation process. This optimization can improve the transmittance and utilization rate of light, so that the product has better optical performance. In addition, the integrally formed structure of the lens 11 and the upper shell 10 can simplify the production process, reduce assembly steps and costs. During the manufacturing process, the materials of the lens 11 and the upper shell 10 can be directly fused or injection molded, thereby avoiding the problem of using adhesives or other connectors in traditional assembly methods. This simplified production process can not only reduce production costs, but also improve production efficiency and product quality. In addition, for products that need to be waterproof and dustproof, the one-piece molding structure of the lens 11 and the upper shell 10 can effectively improve the waterproof and dustproof performance of the product. Since there is no gap or connection gap between them, it can effectively prevent harmful substances such as moisture and dust from entering the interior of the product, thereby extending the service life and reliability of the product.

[0050] In one embodiment, the upper shell 10 and the lower shell 20 are connected and fixed by an ultrasonic welding process. Ultrasonic welding is a fast and efficient connection process. It uses the energy generated by high-frequency vibration to cause the plastic molecules on the contact surface to rub against each other, generate heat and melt, thereby achieving a tight connection between the upper shell 10 and the lower shell 20 in a short time. This connection method is not only fast, but also can ensure the firmness of the connection part and meet the product's requirements for structural strength. In addition, during the connection process, ultrasonic welding can form a tight bond between the plastic molecules due to the effect of vibration energy, thereby effectively preventing the intrusion of water and moisture. This is especially important for products that require waterproof and moisture-proof properties. The upper shell 10 and the lower shell 20 connected by ultrasonic welding can ensure the dryness and stability of the internal environment of the product, thereby extending the service life of the product.

[0051] The waterproof lamp structure is a section of the eaves lamp or the atmosphere lamp. The length of the eaves lamp or the atmosphere lamp can be set according to actual needs, which will not be elaborated here.

[0052] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
