Technical Field
[0001] This utility model relates to the field of lighting technology, specifically to a split-type courtyard light head. Background Technology
[0002] A courtyard light is a type of lighting fixture used for nighttime illumination in residential areas, parks, or scenic spots. Its lamp head typically includes a lampshade, lamp cover, lamp holder, and light-emitting element. The light-emitting element is installed in the cavity formed by the mating of the lampshade and lamp cover, which are then mounted on the lamp holder. Traditional courtyard lights often use a one-piece die-cast lamp cover, and the lampshade is also usually a one-piece molded component. Due to the large size of the lamp cover or lampshade, the molding process is difficult, resulting in a high defect rate and increasing manufacturing costs. Therefore, many courtyard light heads with a split structure have emerged on the market. Existing split-structure courtyard light heads mostly include several light-emitting units and a lamp holder. These light-emitting units are assembled onto the lamp holder to form the lamp head. By breaking down the whole into parts, the light-emitting components are designed as several light-emitting units, significantly reducing the size of the lampshade and lamp cover assembled into the light-emitting units. This also significantly reduces the mold size corresponding to the lampshade and lamp cover, greatly reducing mold development costs and helping to improve the yield rate of both.
[0003] Currently, the problem with split-type courtyard light heads is that when several light-emitting units are installed on a lamp holder to form a courtyard light head, the connection stability between the light-emitting units and the lamp holder is poor. Therefore, when the light-emitting units are subjected to external forces (such as strong winds), they sway, affecting the lighting effect. Furthermore, from a long-term perspective, the lifespan of the courtyard light head is short, and there are certain safety hazards. Therefore, this utility model proposes a split-type courtyard light head to solve the above-mentioned technical problems. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a split-type courtyard light head. Its light-emitting component is composed of several light-emitting units, thus significantly reducing the volume of the lampshade and lamp cover assembled into the light-emitting unit housing compared to traditional one-piece die-cast or injection-molded lamp covers. This effectively reduces the size of the die-casting or injection molding molds, greatly reduces the processing difficulty of the lampshade or lamp cover, significantly improves the processing qualification rate of the lampshade and lamp cover, and effectively solves the problems of high transportation costs and large storage space occupied by the large size of the lamp cover and lamp cover. The lamp cover, lampshade, and light-emitting elements can all be flexibly replaced, allowing for partial maintenance of the courtyard light head and reducing operation and maintenance costs. The second contact surface on the light-emitting unit and the lamp holder... The first contact surfaces on each light source abut together, forming a surface contact between the light-emitting unit and the lamp holder. This significantly improves the installation stability of the light-emitting unit on the lamp holder and its resistance to external forces, eliminating the safety hazard of shaking caused by external wind during installation and use, and helping to extend the service life of the courtyard light head. Different styles of light-emitting units or lamp holders can be freely replaced without replacing the lamp holder, thus changing the shape of the courtyard light head. In other words, the diverse design of the light-emitting unit or lamp holder provides feasibility for a multi-shaped structure design for a single lamp, ensuring that the split courtyard light head of this utility model has a flexible and varied shape, while also helping to greatly reduce the development cost of a lamp.
[0005] To achieve the above objectives, the technical solution of this utility model is to design a split-type courtyard light head, including a lamp holder, on which a plurality of light-emitting units are installed. Each light-emitting unit includes a lampshade, a lamp cover, and a light-emitting element. The light-emitting element is installed in a cavity formed by the lower lampshade and the upper lamp cover being joined together. The lamp holder has a first abutting surface, and the light-emitting units have a plurality of second abutting surfaces. When the plurality of light-emitting units are installed on the lamp holder, the second abutting surfaces on the light-emitting units abut against the first abutting surfaces on the lamp holder one by one.
[0006] This utility model discloses a split-type courtyard light head, whose light-emitting component is composed of several light-emitting units. This significantly reduces the volume of the lampshade and lamp cover assembled into the light-emitting unit housing compared to traditional one-piece cast or injection molded lamp covers. This effectively reduces the size of the casting or injection mold, greatly lowers the processing difficulty of the lampshade or lamp cover, significantly improves the processing qualification rate, and effectively solves the problems of high transportation costs and large storage space required due to the large size of lamp covers and lamp covers. The lamp cover, lampshade, and light-emitting elements can all be flexibly replaced, allowing for partial maintenance of the courtyard light head and reducing operation and maintenance costs. The second contact surface on the light-emitting unit and the first contact surface on the lamp holder are aligned one-to-one. The light-emitting unit and the lamp holder should be joined together to form a surface contact, which significantly improves the installation stability of the light-emitting unit on the lamp holder and its resistance to external forces. This eliminates the safety hazard of shaking caused by external wind during installation and use, and helps to extend the service life of the courtyard light head. Different styles of light-emitting units or lamp holders can be freely replaced without replacing the lamp holder, thus changing the shape of the courtyard light head. In other words, the diversity of light-emitting unit or lamp holder design provides feasibility for a multi-shaped structure design of one lamp, ensuring that the split courtyard light head of this utility model has a flexible and varied shape, while also helping to greatly reduce the development cost of a lamp.
[0007] A preferred technical solution is that the upper end of the lamp holder has several brackets extending radially outward, with a light-emitting unit mounting area formed between two adjacent brackets for accommodating the light-emitting units. The outer peripheral side of the lamp holder is divided into several first abutment surfaces corresponding one-to-one with the light-emitting unit mounting areas by the brackets. The lampshade or lamp cover has a second abutment surface facing the lamp holder, and several mounting plates are protruding from the second abutment surface. The mounting plates are overlapped and fixed to the outer peripheral side of the upper end face of the lamp holder. The light-emitting units are located inside the corresponding light-emitting unit mounting areas, further improving the adaptability of the light-emitting units when assembled on the lamp holder, so that the light-emitting units are evenly distributed in a petal shape on the outer peripheral side of the lamp holder, ensuring the overall aesthetic effect of the split-type courtyard light head of this utility model.
[0008] A further preferred technical solution includes a plurality of screw-hole posts 2 spaced circumferentially around the upper outer periphery of the internal cavity of the lamp holder, and a mounting plate on the light-emitting unit having mounting holes 4. The mounting plates are then screwed together with the screw-hole posts 2 on the lamp holder in a one-to-one correspondence using screws passing through the mounting holes 4. This method of fixing the mounting plates to the upper end of the lamp holder is simple and facilitates disassembly and installation during later maintenance of the light-emitting unit.
[0009] A further preferred technical solution is that both the lampshade and the lamp cover have a fan-shaped structure, and the side of several light-emitting units away from the lamp holder is located on the same circumference.

The lampshade and lamp cover are designed with a fan-shaped structure, so that the side of several light-emitting units away from the lamp holder is located on the same circumference. This makes the overall visual appearance of the split courtyard light head of this utility model a disc-shaped lamp body structure, which helps to improve the visual effect and the overall focused lighting effect. The mounting plate on the light-emitting unit is limited and inserted into the notch and groove on the lamp holder, which improves the installation firmness and positioning accuracy of the light-emitting unit on the lamp holder, and helps to improve the assembly efficiency of the light-emitting unit on the lamp holder.
[0010] A further preferred technical solution includes a screw hole post three on the lower end face of the lamp cover, and a mounting hole on the light-emitting element. The light-emitting element is fixedly connected to the corresponding screw hole post three on the lamp cover by screws passing through the mounting holes. Several heat dissipation fins are spaced apart on the lower end face of the lamp cover. The fixing and installation method of the light-emitting element on the lower end face of the lamp cover is simple, facilitating disassembly and installation. The fins on the lower end face of the lamp cover are in close contact with the upper end face of the light-emitting element, thereby promptly dissipating the heat generated during illumination, effectively preventing overheating damage to the light-emitting circuit components, and helping to extend the overall service life of the light-emitting element.
[0011] A further preferred technical solution includes an arc-shaped connecting arm on the concave side of the lamp cover for connecting the two ends. The arc-shaped connecting arm forms the first abutment surface facing the convex side of the lamp holder. The arc-shaped connecting arm and the concave side of the lamp cover enclose a weight-reducing cavity, and a decorative panel is installed inside the weight-reducing cavity. The weight-reducing cavity formed by the arc-shaped connecting arm and the concave side of the lamp cover significantly reduces the weight of the light-emitting unit, helping to save material resources. Furthermore, the decorative panel embedded inside the weight-reducing cavity further enhances the visual aesthetics of the split-type courtyard light head of this invention.
[0012] A further preferred technical solution includes: four screw-hole posts on the inner peripheral wall of the weight-reducing cavity; five mounting holes on the outer peripheral side of the decorative panel; the decorative panel is embedded inside the weight-reducing cavity and connected to the corresponding screw-hole posts four by screws passing through the mounting holes five; a weight-reducing groove along its length is formed on the upper end face of the arc-shaped connecting arm, and a drainage hole is provided at the bottom of the weight-reducing groove. The installation of the decorative panel inside the weight-reducing cavity is simple; the weight-reducing groove on the arc-shaped connecting arm helps to further reduce the weight of the light-emitting unit while ensuring the strength of the arc-shaped connecting arm; and the drainage hole can promptly drain rainwater accumulated inside the weight-reducing groove, thereby extending the service life of the arc-shaped connecting arm.
[0013] A further preferred technical solution is that an insertion eave is provided on the upper end face of the outer peripheral sidewall of the lampshade or the lower end face of the outer peripheral sidewall of the lamp cover, and the lampshade and the lamp cover are connected together by insertion eave. The insertion eave facilitates the insertion and positioning between the lampshade and the lamp cover, and also helps to ensure the stability of the lampshade and the lamp cover after assembly.
[0014] A further preferred technical solution includes a top cover that is snapped onto the upper end of the lamp holder. The top cover has several arm plates extending outwards, and each arm plate is snapped onto the corresponding support arm. The upper outer periphery of the lamp holder's internal cavity is also provided with several threaded post 1s spaced circumferentially. The top cover has mounting holes 6, and the top cover is screwed and fixedly connected to the corresponding threaded post 1 by screws passing through the mounting holes 6. The lower end of the lamp holder has a rod mounting groove, and the outer periphery of the rod mounting groove has mounting holes 1. The method of fixing the top cover to the lamp holder is simple. The rod mounting groove and mounting holes 1 at the lower end of the lamp holder facilitate the fixing of the split-type courtyard light head of this utility model to the lamp post by screws, significantly improving the installation or maintenance efficiency during use.
[0015] A further preferred technical solution includes an annular partition at the lower end of the internal cavity of the lamp holder, with the pole mounting groove located below the annular partition; a second insertion eave is provided on the lower end face of the upper arm plate of the top cover, and the arm plate is connected to the support arm on the lamp holder by the insertion eave.
