Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment technology, and specifically relates to an eaves lamp. Background Technology

[0002] Currently, common roof lights on the market mainly adopt two technical approaches: The first type uses an independently encapsulated waterproof structure for each light-emitting module, with electrical connections between modules achieved through metal connectors. This type of solution requires individual waterproofing treatment (such as potting and sealing) for each light-emitting module before assembling them into a light strip using connectors. The second type uses flexible circuit boards with pre-welded light-emitting modules, and performs local waterproofing encapsulation on individual modules using ultrasonic welding technology.

[0003] However, both solutions suffer from complex structures and low assembly efficiency. The former requires waterproof encapsulation and connector assembly of each module individually, while the latter relies on high-precision welding or ultrasonic sealing processes. More importantly, due to weak points in the waterproof structure, the connector joints are susceptible to stress and leakage under the influence of outdoor temperature differences, humidity, and other environmental factors. Minor defects in the local sealing process or material aging can also lead to a decline in waterproof performance, ultimately causing short circuits or accelerated light decay, making it difficult to meet the requirements for long-term stable use.

[0004] Therefore, there is an urgent need to develop a roof light solution that is simple in structure, has excellent waterproof performance, and is easy to assemble, in order to solve the reliability problems existing in the current technology. Utility Model Content

[0005] This utility model provides a roof lamp that simplifies the production process while achieving full-path waterproofing and ensuring continuous light field distribution.

[0006] This utility model provides a roof light, comprising: a waterproof light strip with a transparent outer shell and multiple light-emitting modules evenly spaced along the length of the waterproof light strip; an installation unit corresponding to each of the light-emitting modules, each installation unit comprising: a mounting base with a horizontal support surface for placing the corresponding light-emitting module; a top cover comprising a light-transmitting top plate and an annular sidewall extending vertically from the periphery of the light-transmitting top plate, wherein symmetrical limiting grooves are provided on the left and right sides of the annular sidewall for the waterproof light strip to pass through; and a buckle assembly for fixing the mounting base and the top cover, and clamping and fixing the corresponding light-emitting module between the horizontal support surface and the light-transmitting top plate.

[0007] In one embodiment of this utility model, a lens is embedded in the light-transmitting top plate, and the lens covers the light-emitting surface of the corresponding light-emitting module; and the diffusion angle of the lens is a preset angle, so that the light spots of adjacent light-emitting modules form a continuous and seamless superimposed illumination area on the projection surface.

[0008] In one embodiment of this utility model, the preset angle is 80°≤a≤120°.

[0009] In one embodiment of the present invention, the buckle assembly includes: at least a pair of protrusions circumferentially spaced on the horizontal support surface of the mounting base; and a corresponding snap-fit ​​notch on the annular sidewall of the upper cover; when the upper cover is fastened to the mounting base, the protrusions are embedded in the snap-fit ​​notch to form a lock.

[0010] In one embodiment of the present invention, the mounting base further includes a lateral mounting surface perpendicular to the horizontal support surface; the horizontal support surface is provided with a first mounting hole, and the lateral mounting surface is provided with a second mounting hole, so as to realize the top mounting or side mounting of the eaves lamp.

[0011] In one embodiment of this utility model, the horizontal support surface and the lateral mounting surface are integrally formed.

[0012] In one embodiment of this utility model, the inner edge of the limiting groove that contacts the waterproof light strip is provided with a serrated structure for clamping and fixing the waterproof light strip.

[0013] In one embodiment of this utility model, the spacing between the light-emitting modules is 10mm≤L≤80mm.

[0014] In one embodiment of this utility model, both the top cover and the mounting base are made of UV-resistant modified polycarbonate.

[0015] As described above, the eaves lamp of this utility model has the following beneficial effects:

[0016] (1) By integrating multiple light-emitting modules onto a waterproof light strip with a transparent shell, and using the snap-fit ​​fixing structure of the installation unit, an overall waterproof seal is achieved, which effectively solves the leakage risk caused by connectors or partial sealing in traditional solutions, and significantly improves the waterproof reliability and service life of the product.

[0017] (2) The independent installation unit and the waterproof light strip are designed to be detachable. With the multi-directional installation holes of the base, it is easy to quickly assemble and repair on site, and can adapt to different installation scenarios such as top mounting or side mounting, which greatly improves the convenience of construction and the flexibility of application.

[0018] (3) By setting a lens with a specific diffusion angle (80°-120°) on the light-transmitting top plate, the light spots of adjacent light-emitting modules form a seamless superimposed lighting area on the projection surface, effectively eliminating the bright and dark stripe phenomenon generated by traditional discrete modules and obtaining a more uniform and continuous lighting effect.

[0019] (4) The installation base and top cover are made of UV-resistant modified polycarbonate in one piece, and the serrated limiting groove not only enhances the structural strength and anti-aging performance, but also ensures the stable fixation of the waterproof light strip, so that the product can withstand the harsh outdoor environment for a long time.

[0049] The following embodiments of this utility model disclose a roof lamp that simplifies the production process, achieves full-path waterproofing, and ensures continuous light field distribution.

[0050] This embodiment provides a roof lamp, such as Figure 1 As shown, it mainly includes a waterproof light strip 1, an installation unit 2, and a clip assembly 4. The structure and assembly relationship of each component are described in detail below with reference to the attached drawings.

[0051] The waterproof light strip 1 has a transparent outer shell 12 and multiple light-emitting modules 11 are arranged at equal intervals along the length of the waterproof light strip 1.

[0052] Specifically, such as Figure 2 As shown, the waterproof light strip 1 consists of an integrated sealed structure formed by a transparent outer shell 12 and an inner substrate, with the outer shell wrapping around the outside of the substrate to form a continuous waterproof layer. Along the length of the waterproof light strip 1, multiple light-emitting modules 11 are fixed on the substrate at equal intervals, and each module is electrically connected through flexible conductive lines.

[0053] In some embodiments, the spacing of the light-emitting modules 11 is designed to be adjustable. The spacing is precisely controlled by the snap-fit ​​positioning structure of the modules on the substrate, so that the distance between adjacent modules can be flexibly set in the range of 10mm to 80mm according to the lighting requirements.

[0054] The installation unit 2 is set up independently for each light-emitting module 11.

[0055] Specifically, each light-emitting module 11 is configured with an independent mounting unit 2, such as Figure 3 As shown, the mounting unit 2 is composed of a mounting base 21 and a top cover 22. Wherein,

[0056] The mounting base 21 has a horizontal support surface 211, with a positioning area in the center that matches the shape of the light-emitting module 11 for precise support and fixation of the corresponding light-emitting module 11. First mounting holes 213 are distributed along the edge of the support surface, allowing the roof lamp to be top-mounted on a flat surface using bolts or screws. Figure 4 The diagram shown is a schematic of the roof lamp mounted on the ceiling.

[0057] In a further embodiment, the mounting base 21 is extended into an L-shaped structure, that is, a lateral mounting surface 212 extends vertically from one end of the horizontal support surface 211. A second mounting hole 214 is provided on the outer side of the lateral mounting surface 212 for fixing the lamp to a vertical wall or column surface, thereby achieving a side-mounted mode. Figure 5 The diagram shown is a side-mounted schematic of the eaves lamp.

[0058] For example, the horizontal support surface 211 and the lateral mounting surface 212 are seamlessly connected by an integral injection molding process, and a reinforcing rib is provided at the intersection of the two to enhance the overall structural rigidity and ensure load-bearing stability under different installation directions.

[0059] The top cover 22 includes a light-transmitting top plate 221 and an annular sidewall 222 extending vertically from its periphery.

[0060] Specifically, the annular sidewall 222 has symmetrically provided limiting grooves 223 on its left and right sides. The opening direction of the grooves is consistent with the extension direction of the waterproof light strip 1, so that the light strip can pass through multiple installation units 2 to form a continuous arrangement.

[0061] In some embodiments, the inner edge of the limiting groove 223 that contacts the waterproof light strip 1 is provided with a continuous serrated structure 224. When the light strip is inserted into the groove, the sharp protrusions of the serrations form an interlocking clamp with the surface of the light strip, effectively preventing the light strip from axial displacement or radial loosening after installation.

[0062] The light-transmitting top plate 221 covers the light-emitting surface of the light-emitting module 11, and a lens 3 is embedded on its inner side through an in-mold injection molding process to control the light distribution.

[0063] Specifically, the lens 3 has a convex design, with its bottom surface parallel and aligned with the light-emitting surface of the light-emitting module 11, and its top surface protruding above the outer surface of the light-transmitting top plate 221 to form an arc-shaped protrusion. This allows light to be refracted by the lens 3 to form a small hill-shaped light spot with a bright center and gradually weakening edges. The lens 3 has an annular groove around its periphery, which is embedded in a pre-set positioning protrusion on the inner side of the light-transmitting top plate 221 to ensure that the optical axis of the lens 3 coincides with the central axis of the light-emitting module 11 after installation.

[0064] In some embodiments, the diffusion angle of the lens 3 is preset to be 80° to 120°.

[0065] Specifically, the top surface of lens 3 is provided with a concentric circle distribution of microprism structures. By adjusting the radius of curvature of the prism units, the light is made to form a distribution pattern in the horizontal direction that is centrally converged and gently diffused at the edges. When the diffusion angle of lens 3 of adjacent light-emitting modules 11 is within this range, the small hill-shaped light spots of each module form a continuous light band on the projection surface that overlaps in the center and has smoothly connected edges. The bright areas of adjacent light spots overlap each other, while the gradual transition areas at the edges are seamless, completely eliminating the light and dark boundary lines produced by the traditional discrete arrangement.

[0066] For example, the edge of lens 3 is treated with a gradient frosted finish to further soften the brightness abrupt changes at the edge of the light spot and improve visual uniformity.

[0067] In some embodiments, the top cover 22 and the mounting base 21 are made of UV-resistant modified polycarbonate material.

[0068] Specifically, this material is modified by adding UV absorbers and light stabilizers to a polycarbonate substrate, resulting in excellent weather resistance and effective resistance to yellowing and embrittlement caused by UV radiation. The modified material maintains good light transmittance while possessing good mechanical strength and dimensional stability, enabling long-term use in outdoor environments without significant aging. Its surface hardness reaches HB level, providing excellent impact resistance and ensuring the durability of the luminaire under harsh weather conditions.

[0069] The buckle assembly 4 is used to fix the mounting base 21 and the top cover 22, and to clamp and fix the corresponding light-emitting module 11 between the horizontal support surface 211 and the light-transmitting top plate 221.

[0070] In some embodiments, the snap-fit ​​assembly 4 adopts a symmetrically distributed mechanical locking structure, including a design that engages the protrusion 41 on the mounting base 21 with the snap-fit ​​notch 42 on the top cover 22.

[0071] Specifically, such as Figure 6 As shown, the protrusions 41 are equidistantly arranged circumferentially along the edge of the horizontal support surface 211 of the mounting base 21. Each protrusion 41 is hook-shaped, with a reinforcing structure at its root to improve shear strength, and an inclined guide surface at its front end. Correspondingly, the lower end of the annular sidewall 222 of the upper cover 22 has a snap-fit ​​notch 42 matching the number and position of the protrusions 41, and the inner wall of the notch has a wedge-shaped locking surface complementary to the shape of the hook.

[0072] like Figure 7 As shown, when the top cover 22 is fastened to the mounting base 21, the guide surface of the protrusion 41 preferentially contacts the edge of the notch, forcing the annular sidewall 222 to undergo elastic deformation until the barb is fully embedded inside the notch. At this time, the wedge-shaped locking surface forms a surface contact lock with the root of the barb, and at the same time, the sidewall rebounds and resets, generating a pre-tightening force, tightly pressing the light-emitting module 11 between the horizontal support surface 211 and the light-transmitting top plate 221. The sealing groove on the outside of the buckle assembly 4 is embedded with an elastic seal, which is compressed and deformed in the locked state to block the water vapor penetration path.

[0073] In this implementation, the symmetrical distribution of protrusions and notches ensures uniform force distribution at all points during engagement, avoiding the risk of structural deformation due to excessive local stress. This snap-fit ​​assembly achieves quick assembly and disassembly while also providing highly reliable locking and multiple sealing protection functions.

[0074] In summary, this utility model relates to an eaves light, mainly composed of a waterproof light strip and a detachable installation unit. The waterproof light strip is encapsulated in a transparent shell, with multiple light-emitting modules integrated at equal intervals on the internal substrate to form a continuous waterproof lighting body. Each light-emitting module is equipped with an independent installation unit, including a base and a top cover. The base has a horizontal support surface and a lateral mounting surface with separate mounting holes, suitable for top / side mounting; the annular sidewall of the top cover has a serrated limiting groove to fix the light strip, and the light-transmitting top plate is embedded with an 80-120° diffusion angle lens, allowing adjacent light spots to overlap seamlessly. The base and top cover are locked together by symmetrically distributed snap-fit ​​components, using the interlocking of protrusions and notches to generate pre-tightening force, clamping the light-emitting modules between the light-transmitting top plate and the support surface, while embedding sealing components to achieve dust and water resistance. The overall structure is made of UV-resistant modified polycarbonate in one piece, combining high weather resistance, installation flexibility, and uniform and continuous lighting effect, making it particularly suitable for customized lighting projects for outdoor building eaves.
