[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.
[0016] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.
[0017] See Figures 1-4As shown, this specific embodiment adopts the following technical solution: including: lamp body, bracket, and mounting base. The front end of the lamp body is provided with a light source module. The light source module includes a central LED group located in the middle area and an edge LED group surrounding the circumferential edge area of the central LED group. The central LED group and the edge LED group are respectively equipped with lenses. The central LED group is equipped with a direct lens, and the edge LED group is equipped with a wide-angle lens. The bracket includes a connecting seat, a first connecting rod, a second connecting rod, and a third connecting rod. One end of the connecting seat is connected to the lamp body, and the other end is connected to the first connecting rod through a hinge structure. The third connecting rod is connected to the mounting base.
[0018] The lamps in the central lamp group are arranged in a rectangular array to ensure uniform lighting in the central area. The lamps in the edge lamp groups are symmetrically distributed vertically and horizontally along the circumferential edge of the central lamp group to achieve omnidirectional floodlighting. The direct-light lens in the central lamp group is a circular lens to converge light and enhance the brightness of the central lighting. The wide-angle lens in the edge lamp groups is an elliptical lens with an outwardly convex arc-shaped light-emitting surface to increase the light refraction angle and achieve wide-angle diffusion. The convex direction of the elliptical lens extends along the left-right and vertical directions of the lamp body to ensure uniform diffusion of wide-angle light along the circumference of the lamp body.
[0019] The rear of the lamp body is provided with an interface groove. The connecting seat is provided with an interface block that is adapted to the interface groove and can slide laterally into it. The interface block is fixed by a buckle to achieve quick disassembly and assembly and stable connection between the connecting seat and the lamp body. The connecting seat is provided with a hinge joint on the side away from the lamp body. The hinge joint is provided with a shaft hole. The first connecting rod is provided with a shaft hole coaxial with the shaft hole to achieve a rotatable connection. One end of the first connecting rod is rotatably connected to the hinge joint. The two ends of the second connecting rod are respectively rotatably connected to the first connecting rod and the third connecting rod through a hinge shaft. The third connecting rod is rotatably connected to the mounting base through the hinge shaft to achieve flexible rotation of each component. The hinge joint of the connecting seat and the ends of each connecting rod are provided with mutually cooperating arc-shaped protrusions and arc-shaped grooves to improve the hinge stability, reduce swaying, limit the offset of the connecting rod during hinge to prevent excessive rotation, and improve the accuracy of lamp body extension and angle adjustment.
[0020] The working principle of this specific implementation is as follows: the central LED group adopts direct-beam LEDs with a small beam angle, resulting in concentrated light; the edge LED group adopts wide-angle LEDs with a large beam angle, resulting in dispersed light and a wide coverage area; and the extension and tilt angles of the lamp body are adjusted through multiple hinge structures.
[0021] This specific embodiment achieves multi-directional light emission by combining the central LED group with a direct-light lens and the edge LED group with a wide-angle lens, allowing the light to diffuse evenly along the circumference and effectively expanding the lighting coverage. It also adopts a linkage hinge structure and a combination of arc-shaped protrusions and arc-shaped grooves to achieve multi-dimensional adjustment of the lamp body's extension distance and illumination angle.
[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description; thus, all variations falling within the meaning and scope of equivalents of the claims are included within this invention.
[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
