The upper case 10 and the lower case 20 form a receiving space, which receiving space is provided with a PCB lamp board 40, and two sides of the receiving space are provided with a recess 21 and an outwardly extending installation part 22. The installation part 22 is provided with a transversely extending elastic strip 23. The wire 30 passes through the recess 21 along the installation part 22 and is electrically connected to the PCB lamp board 40, with the wire 30 abutting against the transverse elastic strip 23.In one embodiment, the provision of the recess 21 on two sides of the receiving space as well as the provision of the installation part 22 and the transverse elastic strip 23 causes the wire 30 to undergo compressive deformation with the transverse elastic strip 23 when the wire passes through the recess and is electrically connected to the PCB lamp board. This design can utilize elasticity of the elastic strip and compression of the wire 30 forming a dense waterproof seal, thereby preventing moisture from entering the interior through a connection between the wire 30 and the housing, thereby significantly improving the waterproof level of the lamp and having high convenience. In one embodiment, by forming the accommodation space between the upper case 10 and the upper case 20, internal electronic components such as the PCB lamp board 40 can be effectively protected from harmful substances such as external moisture and dust, which is critical for ensuring stable operation and extending the life of the lamp. In addition, the waterproof lamp structure can be applied to various harsh environments such as moisture and high water due to its excellent waterproof performance. This not only extends an application range of the lamp but also improves its reliability and durability, whereby the lamp is capable of maintaining stable lighting effects in various environments.In one embodiment, the transverse elastic strip 23 is wave-shaped provided on the installation part 22.In one implementation manner, an adjustment direction of the transverse elastic strip 23 and an adjustment direction of the wire 30 are arranged in a cruciform manner. The wavy design increases a contact area between the transverse elastic strip 23 and the wire 30 as compared to a flat design. This not only enhances physical contact, but also achieves a tight fit between the wire 30 and the elastic strip at multiple points by wave shape of the wave. This close contact helps reduce a gap between the wire 30 and the elastic strip, thereby improving overall bond stability and strength. Moreover, the configuration of the corrugated transverse elastic strip 23 also improves its fixing effect on the wire 30, and due to the corrugated configuration, the wire 30, when placed on the elastic strip, is subjected to a plurality of compressive forces from the peaks and valleys of the corrugations, thereby helping to firmly fix the wire 30 to the elastic strip; at the same time, the corrugated configuration further improves the slip resistance of the wire 30 on the elastic strip, thereby making the wire 30 less likely to slip or shift from the elastic strip even under the influence of an external force. In addition, the wavy transverse elastic strip 23 can optimize stress distribution between the wire 30 and the elastic strip. When under tension, the wavy elastic strip can more effectively distribute tension and avoid damage due to stress concentration. This ability to distribute stress not only improves the load bearing capacity of the entire structure, but also extends the life of the elastic strip and the wire 30.In one embodiment, the transverse elastic strip 23 is circular, triangular or diamond shaped.In particular, the circular, triangular or diamond shaped transverse elastic strip 23 can adhere better to a surface of the wire 30 due to its unique geometric shape. This close contact helps reduce a gap between the wire 30 and the elastic strip, thereby improving overall bond stability and strength. And this shaped elastic strip usually has good elastic deformation capability, and can undergo moderate deformation upon application of an external force, thereby more easily adapting to the shape and size changes of the wire 30. This deformability helps maintain continuous intimate contact between the wire 30 and the elastic strip, further improving the sealing effect. In addition, the circular, triangular, or diamond-shaped transverse elastic strip 23 can increase a frictional force of the wire 30 on the elastic strip due to its irregularity in shape, thereby improving the slip resistance of the wire 30. This slip resistance helps ensure that the wire 30 does not fall or shift due to external forces during long term use. In one embodiment, the transverse elastic strip 23 is circular.In a specific embodiment, the height of the transverse elastic strip 23 is 0.05 mm to 0.3 mm.In particular, the height of the transverse elastic strip 23 is in the range of 0.05 mm to 0.3 mm, this ensuring a firm contact between it and the wire 30. This tight contact helps to reduce a gap between the wire 30 and the elastic strip, preventing the ingress of moisture or other harmful substances into the interior of the waterproof lamp structure through the gap. Therefore, the design of this height is critical for maintaining the sealing performance of the waterproof lamp structure. In addition, the transverse elastic strip 23 can maintain good elastic deformation capability within the height range of 0.05 mm to 0.3 mm. This means that when the wire 30 is placed on the elastic strip, the elastic strip can undergo moderate deformation to conform to the shape and size of the wire 30. This deformability helps not only maintain close contact between the wire 30 and the elastic strip, but also distributes stress under load, thereby avoiding damage due to stress concentration. In addition, the height range of 0.05 mm to 0.3 mm allows the transverse elastic strip 23 to adapt to the wires 30 having different specifications. This means that when designing and manufacturing the waterproof lamp structure, different heights of elastic strips can be selected to meet the requirements of different wires 30. This flexibility helps to lower production costs and improve production efficiency.In one embodiment, the transverse elastic strip 23 is integrally formed with the installation part 22.In particular, the design of the integrated structure ensures that there are no joints or joints between the transverse elastic strip 23 and the installation part 22. This seamless connection not only improves strength of the entire structure but also improves stability thereof; when under stress, the integrated structure can more effectively distribute stress and prevent damage due to stress concentration, thereby prolonging the service life of the waterproof lamp structure. In addition, since the transverse elastic strip 23 is integrally molded with the installation part 22, its bonding is narrower without gaps by poor bonding. This tight bond helps reduce the ingress of moisture or other harmful substances and improve the sealing performance of the watertight lamp structure. In moist or harsh environments, this sealing performance is especially important to ensure normal operation and useful life of the waterproof lamp structure.In an embodiment, as shown in FIGS. 4 and 5, both the upper housing 10 and the lower housing 20 are provided with the recess 21 and the installation part 22.Specifically, by providing the recess 21 and the installation part 22 on both the upper case 10 and the lower case 20, the wire 30 can be in close contact with the transverse elastic strip 23 at two ends. This double-end contact manner can more effectively compress an outer skin of the wire 30, thereby deforming and firmly adhering to the elastic strip. This tight fit helps reduce the gap between the wire 30 and the housing, thereby preventing moisture or other harmful substances from entering the waterproof structure through the gap, thereby significantly improving the waterproof sealing effect. In addition, due to the compression and fixation of the wire 30 by the transverse elastic strip 23 at two ends, this technology can improve reliability of the waterproof structure. Even if the wire 30 undergoes slight deformation by force or temperature changes during long-term use, the presence of the double end fixation can maintain close contact between it and the elastic strip, thereby ensuring continuous stability of waterproofing performance. In addition, due to the compression and fixation of the wire 30 by the transverse elastic strip 23 at two 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 improve the durability of the waterproof structure and extend its useful life.In an embodiment, the upper housing 10 is further provided with a lens 11.Specifically, the PCB lamp board 40 uses existing publicly available technology, which will not be discussed here. At this time, the lens 11 can accurately control the direction and angle of light propagation, thereby ensuring that the light is emitted along a predetermined path. This control effect enables the light to be directed more concentratedly and efficiently to a target area, thereby improving light emission efficiency. In addition, by reasonable design of the shape and size of the lens 11, the angle of scattering and range of light can be adjusted. This matching effect allows the light to illuminate a wider area, thereby expanding an illumination area. In scenes requiring large area illumination, this effect of the lens 11 can significantly improve an illumination effect.In one embodiment, the lens 11 is hemispherical.Specifically, the semi-spherical lens 11 can focus light parallel to a center line of the lens 11 to a point called a focal point, which is known as a focusing effect of the lens 11. By utilizing this effect, the semi-spherical lens 11 can enhance the light, thereby being more concentrated and, after passing through the lens 11, shines on a target area, thereby improving brightness and illumination effect of the light. In addition, when light passes through the semi-spherical lens 11, the light undergoes refraction due to different refractive indices of the lens 11 and a surrounding medium. By reasonable construction of the shape and size of the lens 11, the angle of refraction and the direction of the light can be controlled so that the light can propagate along a predetermined path. This directional control is particularly important in lighting devices, which can ensure that the light can accurately illuminate the area that needs to be illuminated.In one embodiment, the lens 11 is convex or concave hemispherical.Specifically, the convex hemisphere is used for focusing and the concave hemisphere is used for scattering. Here, the convex hemispherical lens 11 has a property of focusing parallel light beams at a point. As the light rays pass through the convex hemispherical lens 11, they are focused and refracted toward a center of the lens 11 and form a clear focus on the other side of the lens 11. In addition, due to an ability of the convex hemispherical lens 11 to focus light on a single point, a utilization rate of the light can be significantly improved. In situations where the light source intensity is limited, the convex hemispherical lens 11 may be used to ensure that more light is effectively used for illumination. Unlike the convex hemispherical lens 11, the concave hemispherical lens 11 has a property of scattering light rays. As light passes through the concave hemispherical lens 11, it breaks toward an edge of the lens 11 and forms diverging light rays; this property makes the concave hemispherical lens 11 very useful in scenes requiring large area, low intensity illumination. In addition, a scattering effect of the concave hemispherical lens 11 can widen the illumination range, thereby more evenly distributing light over the entire illumination range. This property is especially important in scenes requiring large area illumination, such as household lighting, office lighting, etc.In one embodiment, the lens 11 is integrally formed with the upper housing 10.Specifically, when the lens 11 is integrally molded with the upper case 10, its connection becomes stronger and more stable. This structural shape can effectively reduce loosening or damage due to long-term use or external environmental factors (such as vibration, shock, etc.), thereby improving the structural strength and stability of the entire product. In addition, the integrally molded structure helps reduce the gap and air layer between the lens 11 and the upper housing 10, thereby reducing the refractive and reflection losses of light during propagation. This optimization can improve the transmission and utilization of light, thereby providing the product with better optical performance. In addition, the integrally molded structure of the lens 11 and the upper housing 10 can simplify the production process, reduce assembly methods, and cost. During a manufacturing process, the materials of the lens 11 and the upper housing 10 may be directly fused or injection molded, thereby avoiding the problem of using adhesives or other connectors in traditional assembly ways. This simplified production process not only reduces production costs but also improves production efficiency and product quality. In addition, for products that require water and dust-proof properties, the integrally molded structure of the lens 11 and the upper housing 10 effectively improves the water and dust-proof performance of the product. Since there is no gap or joint between them, harmful substances such as moisture and dust can be effectively prevented from entering the inside of the product, thereby prolonging the useful life and reliability of the product.In one embodiment, the upper housing 10 and the lower housing 20 are joined and fixed by an ultrasonic welding process. Ultrasonic welding is a quick and efficient joining method in which energy is generated by high frequency vibration, causing plastic molecules on a contact surface to rub against each other, generate heat, and melt, thereby achieving a firm joint between the upper housing 10 and the lower housing 20 in a short time. This bonding manner is not only fast, but also ensures the strength of the bonding part and satisfies a structural strength requirement of the product.In addition, ultrasonic welding can form a dense bond between plastic molecules due to the action of the vibration energy during the bonding process, thereby effectively preventing the penetration of vapor and moisture. This is especially important for products that require water and moisture proof performance. The upper case 10 and the lower case 20 joined by ultrasonic welding can ensure dryness and stability of an internal environment of the product, thereby prolonging its useful life.Here, the waterproof lamp structure is a portion of a eaves lamp or an atmospheric lamp, and a length of the eaves lamp or the atmospheric lamp may be adjusted according to actual needs, which will not be discussed in detail here.The above embodiments are the preferred embodiment scheme of the present disclosure. In addition, the present disclosure may be also carried out in other ways, and any obvious replacement falls within the scope of the present disclosure without departing from the concept of the technical solution.
