[0032] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0033] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0034] like Figures 1-6As shown, an LED lampshade of this application includes an upper lampshade housing 1, a lower lampshade housing 2, an interlocking protrusion 3, an interlocking groove 4, heat dissipation fins 5, and a fixing hole 6.

[0035] The upper housing 1 of the lampshade is located above the LED light source and is used to cover and protect the upper area of ​​the light source. Its edge area is designed with a joint structure to achieve a detachable connection. The housing is made of lightweight thermoplastic material and is manufactured by injection molding to form a hollow semi-domed structure, which facilitates light diffusion and heat transfer. During installation, it is engaged with the lower housing 2 of the lampshade by interlocking protrusions 3 on the edge to ensure overall sealing and stability. For example, the molding process ensures a smooth surface and reduces light loss.

[0036] The lower housing 2 of the lampshade is located below the LED light source to cover the lower area of ​​the light source and provide heat dissipation and fixation functions. This housing has a flat or curved design, is made of a high thermal conductivity polymer or metal alloy, and is manufactured through integral molding or assembly. Its edges are provided with interlocking grooves 4 to accommodate the interlocking protrusions 3 of the upper housing 1 of the lampshade, while the outer surface integrates heat dissipation fins 5 and fixing holes 6. In applications, for example, the groove structure is formed through an extrusion process, ensuring that the internal space of the housing accommodates the LED module to optimize thermal management.

[0037] An interlocking protrusion 3 is located on the edge of the upper housing 1 of the lampshade and is used for detachable engagement with the interlocking groove 4 of the lower housing 2 of the lampshade. Its structure includes a main body and an extension 7, which extends from the main body toward the lower housing 2 of the lampshade and has a locking hook 8 at its end. The root of the locking hook 8 has an elastically deformable section 9 that provides pre-tightening force during assembly. This protrusion is manufactured by injection molding or stamping. The locking hook 8 is designed using an elastic material such as polycarbonate. In technical implementation, for example, the extension 7 is formed into a hook-like structure through in-mold molding. The elastically deformable section 9 allows the hook to bend controllably when inserted into the groove, achieving rapid locking and release.

[0038] An interlocking groove 4 is formed on the edge of the lower housing 2 of the lampshade to accommodate the interlocking protrusion 3 for interlocking at the joint. Its structure is a continuous or discontinuous groove with a smooth inner wall to facilitate engagement of the locking hook 8. This groove is manufactured by molding or cutting, for example, directly forming a U-shaped or dovetail-shaped groove during injection molding to ensure a tight fit with the extension 7 of the protrusion. During installation, the depth and width of the groove match the size of the protrusion, facilitating manual alignment and fixation by the user and improving assembly efficiency.

[0039] Heat dissipation fins 5 are attached to the outer surface of the lower housing 2 of the lampshade to enhance heat dissipation performance. Their structure consists of multiple parallel or radial fin arrays, directly connected or integrally molded onto the housing. The fins are manufactured using thermally conductive materials such as aluminum alloy or thermally conductive plastics, for example, by extrusion or die-casting processes to form a thin sheet structure, increasing the surface area to promote air convection. In technical implementation, the fin height and spacing are optimized, for example, by determining the optimal parameters through computational fluid dynamics simulations, effectively dissipating the heat generated by the LED and preventing overheating.

[0040] Fixing holes 6 are formed on the lower housing 2 of the lampshade and are used to fix the lampshade to the external bracket by bolts. These holes are circular or square through holes, located on the edge or center of the housing. They are manufactured by drilling, stamping, or injection molding, for example, by setting a core in a mold to form a precise hole diameter. In application, threaded bushings or washers can be added inside the holes to enhance the connection strength, facilitating the secure installation of the lampshade onto the bracket using standard bolts, ensuring overall vibration resistance and durability.

[0041] The LED lampshade of this application solves the technical problem of improving overall structural strength and dustproof performance through the interlocking design of the interlocking protrusion 3 and the interlocking groove 4. Specifically, the locking hook 8 at the end of the extension 7 of the interlocking protrusion 3 engages with the inner wall of the interlocking groove 4. During assembly, the elastic deformation section 9 of the locking hook 8 undergoes elastic deformation, providing a continuous preload force to form a tight seal at the joint. This enhances the mechanical locking between the housings, resists external impacts and vibrations, and thus improves structural strength. At the same time, the preload force ensures that the gap at the joint is minimized, effectively preventing dust and moisture from entering and achieving a dustproof seal. For example, during assembly, the compressive force of the elastic deformation section 9 maintains the fit between the hook and the groove wall, forming a labyrinthine seal effect, which, combined with the elasticity of the housing material, further enhances the protective performance.

[0042] like Figure 1 As shown, in one embodiment, a reinforcing rib 10 is provided on the edge region of the upper housing 1 of the lampshade. The reinforcing rib 10 is continuously distributed along the entire edge to form an integrated structural reinforcement member. Specifically, the reinforcing rib 10 is located on the outer or inner edge of the upper housing 1 of the lampshade, adjacent to the mounting position of the interlocking protrusion 3, to directly support the interlocking area. The cross-section of the reinforcing rib 10 is typically in the form of a protrusion or groove, with uniform thickness and height, thereby resisting deformation or stress concentration during interlocking.

[0043] Specifically, the continuous distribution of the reinforcing ribs 10 ensures an overall increase in edge rigidity, avoiding localized weaknesses. For example, the reinforcing ribs 10 can be linear or wavy, with their length covering the entire set range of the interlocking protrusions 3, and integrally formed with the material of the upper housing 1 of the lampshade. This configuration strengthens the structural integrity of the interlocking area by increasing material thickness or optimizing geometry.

[0044] For example, the edge of the housing 1 on the lampshade is formed with continuous raised reinforcing ribs 10 by injection molding. The reinforcing ribs 10 are arranged parallel to the extension direction of the interlocking protrusions 3 and are seamlessly connected to the housing base, thereby providing additional support during assembly to prevent loosening or separation of the interlocking area.

[0045] like Figure 6 As shown, in one embodiment, a support block 11 is added to the bottom of the interlocking protrusion 3 of the housing 1. This support block 11 is integrally formed with the upper housing 1 of the lampshade, aiming to improve the structural rigidity of the interlocking protrusion 3. Specifically, the support block 11 is located in the bottom region of the interlocking protrusion 3, that is, close to the main body of the upper housing 1 of the lampshade. Its mounting position is directly attached to the base of the interlocking protrusion 3, thereby providing additional support at the connection between the interlocking protrusion 3 and the upper housing 1 of the lampshade. This design effectively prevents bending or deformation that may occur under assembly or external stress by strengthening the root region of the interlocking protrusion 3.

[0046] Specifically, the support block 11 is a block-shaped solid, and its shape and size are optimized according to the geometric features of the interlocking protrusions 3, such as using a rectangular or trapezoidal profile to ensure uniform load distribution. The integral molding connection between the support block 11 and the upper housing 1 of the lampshade eliminates seams or gaps in traditional assembly, forming a continuous integral structure, which helps to improve the overall mechanical strength. Specifically, integral molding means that the support block 11 is completely fused with the material of the upper housing 1 of the lampshade during the manufacturing process, without any separation interface.

[0047] For example, the support block 11 can be achieved through injection molding, in which a corresponding cavity is added during the mold design stage, so that the support block 11, the bottom of the interlocking protrusion 3 and the main body of the upper housing 1 of the lampshade are formed simultaneously. For example, thermoplastic materials such as polycarbonate or ABS are used, and after cooling and solidification, a seamless structural unit is formed.

[0048] like Figure 5 As shown, in one embodiment, an interlocking groove 4 is formed at the edge of the lower housing 2 of the lampshade to accommodate the interlocking protrusion 3 for removable interlocking at the joint. This feature involves embedding a sealing strip 12 in the inner wall of the interlocking groove 4. The sealing strip 12 is made of an elastic material, such as rubber or silicone polymers, and its structure is designed as a strip or annular cross-section to fit the contour of the inner wall of the groove. The sealing strip 12 is embedded by press-fit or snap-fit, securing it firmly to the inner surface of the groove, thereby forming a continuous dust barrier at the joint. Through the deformation properties of the elastic material, the sealing strip 12, after assembly, tightly conforms to the contact area between the interlocking protrusion 3 and the groove, preventing external dust or particles from entering the interior of the lampshade.

[0049] Specifically, the structural composition of the sealing strip 12 ensures its durability and sealing performance, while the selection of the elastic material takes into account environmental adaptability, such as high-temperature resistance and anti-aging properties, to maintain reliability for long-term use. This design complements the overall sealing effect of the interlocking mechanism, providing an additional protective layer at the joints without interfering with the original interlocking function.

[0050] For example, the silicone sealing strip 12 is pressed into the inner wall groove of the interlocking groove 4 through a pre-forming process. The inner wall of the groove is provided with a matching slot structure. After the sealing strip 12 is embedded, it achieves self-locking fixation through elastic deformation. Specifically, during the assembly process, the sealing strip 12 is compressed in the meshing area of ​​the interlocking protrusion 3 and the groove to form a continuous annular barrier to prevent dust from entering the joint.

[0051] like Figure 5 As shown, in one embodiment, the interlocking groove 4 of the lower housing 2 of an LED lampshade of this application is provided with a guide slope 13 at its opening. The guide slope 13 is located at the edge of the groove entrance, specifically formed on the upper or side edge of the opening, and is used to guide the insertion path of the interlocking protrusion 3 during assembly. The guide slope 13 is designed as an inwardly inclined ramp structure with a smooth surface transition to reduce the resistance when the interlocking protrusion 3 enters, thereby optimizing the assembly process. Specifically, the guide slope 13 is continuously connected to the wall of the interlocking groove 4, forming a tapered transition portion at the groove opening, ensuring that the interlocking protrusion 3 can slide into the groove along the slope, avoiding impact or misalignment during initial contact.

[0052] Specifically, the inclination angle of the guide ramp 13 is configured to match the contour of the interlocking protrusion 3, for example, in the range of 10 to 60 degrees, to facilitate the smooth entry of the protrusion body into the groove. This ramp structure is integrally molded with the lower housing 2 of the lampshade, forming part of the groove without the need for additional components. In terms of connection, the guide ramp 13 is directly attached to the opening edge of the interlocking groove 4, its length covering the entire width or part of the opening to provide comprehensive guidance. Through this design, the guide ramp 13 promotes precise alignment between the interlocking protrusion 3 and the interlocking groove 4, reducing assembly stress.

[0053] For example, the guide slope 13 is directly formed on the lower housing 2 of the lampshade through mold injection molding process. Its tilt angle is set to 30 degrees and extends along the entire circumference of the opening of the interlocking groove 4, so that the interlocking protrusion 3 can smoothly slide into the groove during the insertion process, realizing a jam-free assembly operation.

[0054] like Figure 6As shown, in one embodiment, a reinforcing rib 15 is added to the root of the extension 7, directly connecting the extension 7 to the main body of the interlocking protrusion 3. The reinforcing rib 15, as a structural strengthening element, is located in the starting region of the extension 7, near the connection point to the main body of the interlocking protrusion 3, forming a rigid connection through bridging. This design can be implemented as a single piece or as an additional component, ensuring that the reinforcing rib 15 establishes a stable support structure between the extension 7 and the main body. The geometric shape of the reinforcing rib 15 can be rib-shaped with a specific cross-section (such as a triangle or rectangle) to enhance bending stiffness, thereby effectively suppressing local deformation caused by assembly stress, external loads, or thermal expansion.

[0055] Specifically, the reinforcing rib 15 of an LED lampshade of this application is integrally manufactured with the upper housing 1 of the lampshade by injection molding process. For example, a corresponding rib groove structure is designed in the mold so that the reinforcing rib 15 extends directly from the main body area of ​​the interlocking protrusion 3 to the root of the extension 7. Specifically, the reinforcing rib 15 adopts a uniform thickness or a gradually changing cross section to optimize material distribution and connection strength.

[0056] like Figure 6 As shown, in one embodiment, the hook portion of the locking hook 8 is designed in a barb shape. This structure is located at the end of the extension 7 of the interlocking protrusion 3 and is used to engage with the inner wall of the interlocking groove 4. The barb shape 16 enhances the gripping ability of the hook portion during assembly, providing additional locking force through its curved end portion. Specifically, the bending angle of the end of the barb shape 16 is limited to between 30 and 45 degrees. This range ensures optimized engagement strength while avoiding insufficient engagement due to an excessively small angle or assembly resistance caused by an excessively large angle. During interlocking, the elastic deformation section 9 of the locking hook 8 allows the hook portion to elastically deform when inserted into the interlocking groove 4, and then recover to fix the joint position, thereby improving the overall structural stability.

[0057] For example, a custom mold is used to shape plastic material into a hook-shaped 16 structure, where the end bending angle is precisely controlled within the range of 30 to 45 degrees. Specifically, the bending curvature of the mold is adjusted to ensure angle consistency, thereby optimizing the engagement strength with the inner wall of the interlocking groove 4.

[0058] like Figure 2As shown, in one embodiment, the heat dissipation fin 5 base of an LED lampshade of this application is provided with a mounting groove 18. The mounting groove 18 is configured to engage with a protruding rail 19 on the outer surface of the lower housing 2 of the lampshade to enhance the adhesion and heat dissipation efficiency between the heat dissipation fin 5 and the lower housing 2 of the lampshade. Specifically, the mounting groove 18 is formed on the bottom or side surface of the heat dissipation fin 5 base as a recessed structure, while the protruding rail 19 extends continuously or intermittently along the outer surface of the lower housing 2 of the lampshade as a raised structure. The engagement method involves the geometric matching of the mounting groove 18 and the protruding rail 19, such as achieving mechanical locking through sliding or pressing fit, thereby increasing the contact area and heat conduction path.

[0059] Specifically, the depth and width of the mounting groove 18 are adapted to the dimensions of the convex rail 19 to ensure a stable connection after fitting. The convex rail 19 can be arranged parallel to the longitudinal or circumferential direction of the lower housing 2 of the lampshade to optimize heat flow distribution. This structure improves the efficiency of heat transfer from the lower housing 2 of the lampshade to the heat dissipation fins 5 by reducing thermal resistance, while preventing loosening.

[0060] For example, the mounting groove 18 is designed in the shape of a dovetail groove, the convex rail 19 adopts a corresponding dovetail protrusion, and the heat dissipation fins 5 are fitted into place by sliding along the direction of the convex rail 19; or, an elastic material is used to generate a pre-tightening force when the mounting groove 18 is pressed in, so as to enhance the adhesion and heat dissipation performance.

[0061] like Figure 1 As shown, in one embodiment, the wall of the fixing hole 6 is lined with a buffer sleeve 17, which is directly embedded in the hole wall and forms a tight contact with it. This lining structure ensures that the buffer sleeve 17 is firmly fixed in the hole wall and absorbs external vibrations through its elastic properties, thereby reducing stress transmission at the bolt connection. At the same time, the sealing effect of the buffer sleeve 17 extends to the joint area of ​​the lampshade, preventing dust or moisture intrusion by maintaining pressure balance at the joint and improving the overall sealing performance.

[0062] Specifically, the buffer sleeve 17 is made of rubber, possessing elasticity and weather resistance. Its structure is an annular sleeve, with an inner diameter matching the diameter of the fixing hole 6. During assembly, the buffer sleeve 17 is embedded into the hole wall by pressing or bonding, forming a seamless liner and ensuring no gaps between the hole wall and the buffer sleeve 17. This design not only optimizes vibration absorption efficiency but also enhances sealing continuity, preventing deformation or leakage caused by bolt tightening.

[0063] For example, in the manufacturing process of the lower housing 2 of the lampshade, the surface of the hole wall is first treated to a rough texture, and then liquid rubber is injected into the hole wall cavity. After curing, it forms an integral liner. Specifically, the process includes positioning molds to ensure that the buffer sleeve 17 evenly covers the hole wall, thereby providing stable cushioning and sealing support when assembling bolts.

[0064] like Figure 6As shown, in one embodiment, a dustproof mesh 14 is added to the mating surface area of ​​the interlocking protrusion 3 and the interlocking groove 4, located at the mating point between the edge of the upper housing 1 and the edge of the lower housing 2 of the lampshade. Specifically, the dustproof mesh 14 covers the joint gap formed by the interlocking protrusion 3 and the interlocking groove 4 to prevent external dust from seeping into the lampshade through this gap. In terms of installation position, the dustproof mesh 14 is directly arranged in the contact area of ​​the mating surface, ensuring that after the interlocking protrusion 3 and the interlocking groove 4 are detachably joined, the mesh can effectively cover the gap without affecting the original interlocking function.

[0065] Specifically, the structure of the dustproof mesh 14 may include a porous mesh material, such as woven polymer or metal wire, with pore sizes configured to block fine dust particles. The mesh is attached to the mating surfaces by a fixed method, such as by adhesives or mechanical clips, ensuring stable coverage during assembly. In terms of connection, the dustproof mesh 14 may be designed as a single-layer or double-layer layout, directly abutting the opposing surfaces of the interlocking protrusions 3 and interlocking grooves 4 to enhance the sealing of the gaps while allowing relative movement of the mating surfaces.

[0066] For example, a dustproof mesh 14 is provided on the inner wall of the interlocking groove 4. The mesh is made of elastic polymer and embedded in the surface of the groove. It is fixed by hot pressing, so that when the interlocking protrusion 3 is inserted into the interlocking groove 4, the mesh automatically covers the joint gap and achieves dust blocking.

[0067] In actual operation, when this device is used, firstly, the upper housing 1 of the lampshade covers the upper part of the LED light source, and at the same time, the lower housing 2 of the lampshade covers the lower part of the LED light source. Then, by aligning the interlocking protrusion 3 on the edge of the upper housing 1 with the interlocking groove 4 on the edge of the lower housing 2, the locking hook 8 at the end of the extension 7 of the interlocking protrusion 3 engages with the inner wall of the interlocking groove 4. At this time, the elastic deformation section 9 at the root of the locking hook 8 undergoes elastic deformation, providing pre-tightening force to achieve interlocking connection at the joint, enhancing structural strength and dustproof sealing. Then, the lampshade is fixed to the external bracket with bolts through the fixing holes 6 on the lower housing 2. During use, the heat dissipation fins 5 attached to the outer surface of the lower housing 2 continuously enhance the heat dissipation effect.

[0068] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
