Description
Technical Field

[0002] Spotlights are a type of indoor decorative lighting fixture. Conventional spotlights have a rotatable connection between the lamp body and the cover via a shaft, resulting in significant light leakage during angle adjustment. To address this issue, Chinese Patent 202420638403.8 describes a guide-sliding spotlight structure. This structure primarily uses an arc-shaped slide rail on a C-shaped sliding base, with the bottom surface of the lamp body and the arc-shaped slide rail in a surface-to-surface fit. This not only allows for angle adjustment via the arc-shaped slide rail but also improves the effectiveness of preventing light leakage. However, in practical applications, there is an angle adjustment obstruction area between the lamp body and the cover, leading to significant light leakage during angle adjustment. Furthermore, the aforementioned technical solution cannot effectively solve the problem, thus affecting the lighting efficiency. Summary of the Invention

Detailed Implementation
[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0051] Example
[0052] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a light-leakage-proof spotlight structure includes a face ring 1, a C-shaped support base 2 fixed inside the face ring at the bottom, and a lamp structure 3 slidably disposed on the C-shaped support base. A light-leakage-proof structure 4 is provided at the connection between the lamp structure and the C-shaped support base. In this embodiment, the face ring is a conventional structure of the prior art, with a lamp cup inside and mounting springs fixed on the outer wall by rivets or screws. During installation, it is fixed in the mounting hole in the ceiling. The C-shaped support base is also a conventional structure of the prior art, including a bottom mounting part and a top C-shaped connecting part. The bottom mounting part can be circular or C-shaped, and it is mainly used for installation inside the face ring. The top C-shaped connecting part protrudes from the top surface of the face ring and is used to connect the lamp structure.
[0053] In this embodiment, the top surface of the C-shaped support base is an arched surface, and the middle part of the arched surface is located in the middle of the top surfaces of the two side arms of the C-shaped support base. The symmetrical outer wall of the C-shaped support base is provided with a snap-fit strip groove 5. The arc angle of the arched surface can be processed and set as needed, and the middle part of the arched surface is located in the middle of the top surfaces of the two side arms of the C-shaped support base. That is, after installation, the lamp structure can move towards the opening of the C-shaped support base and realize the adjustment of the illumination angle of the lamp structure under the action of the arched surface.
[0054] like Figure 2 , Figure 3 and Figure 4 As shown, the light leakage prevention structure includes a first C-shaped light leakage prevention plate 41 and a second C-shaped light leakage prevention plate 42. The first C-shaped light leakage prevention plate is snapped onto the arc-shaped edge of the C-shaped support base. A snap-fit protrusion 43 is integrally formed on the symmetrical inner wall of the second C-shaped light leakage prevention plate. During assembly, the second C-shaped light leakage prevention plate is positioned at the side opening of the C-shaped support base, and the snap-fit protrusion is inserted into the snap-fit groove for limitation. This structure facilitates the disassembly, assembly, replacement, and maintenance of both structures, and also reduces processing difficulty. Both the first C-shaped light leakage prevention plate and the second light leakage prevention plate are made of plastic. The thickness of the plastic plate is 1-3 mm. The plastic plate has a certain range of deformability, thus ensuring effective contact between the lamp structure and the first and second C-shaped light leakage prevention plates during lamp structure angle adjustment, thereby effectively preventing light leakage. In practical applications, the width between the two buckle protrusions is slightly smaller than the distance between the two buckle grooves. Therefore, when the buckle is inserted, the plastic's deformation properties allow the buckle protrusions to be clamped and positioned within the buckle grooves, ensuring stable installation and preventing loosening or detachment.
[0055] During assembly, the lamp structure is attached to the arched surface and moves across the arched surface to adjust the angle. When the lamp structure rotates on the C-shaped support base to adjust the angle, the first C-shaped light leakage prevention plate and the second C-shaped light leakage prevention plate are respectively attached to the periphery of the lamp structure to prevent light leakage.
[0056] like Figure 2 , Figure 5 and Figure 6 As shown, an arc-shaped guide groove 6 is provided on the symmetrical inner wall of the C-shaped support base; and the lamp structure includes a heat sink 31, a light guide ring 32 and a light source plate 33; the heat sink and the light source plate are conventional structures of the prior art, and are simply applied; the height of the light guide ring can be processed and set as needed, and the outer diameter of the light guide ring matches the inner diameter of the upper opening of the C-shaped support base.
[0057] During assembly, a light source cavity is provided on the bottom surface of the heat sink; the upper part of the light guide ring is inserted into the light source cavity of the heat sink and fixed by screws; the light source plate is fixed to the top wall of the light source cavity by screws and is located in the inner ring of the light guide ring.
[0058] like Figure 5As shown, the inner wall of the C-shaped support base is integrally formed with a protruding edge 7; the width of the protruding edge can be processed and set as needed, and the shape of the protruding edge is the same as the shape of the arched surface. An arc-shaped guide protrusion 8 is integrally formed on the upper part of the outer wall of the light guide ring, and its shape matches the top surface of the C-shaped support base; the width of the arc-shaped guide protrusion can be processed and set as needed, and its width is less than the width of the protruding edge. An arc-shaped rib 9 that matches the arc-shaped guide groove is provided on the symmetrical outer wall of the arc-shaped guide protrusion. During assembly, the light guide ring is located inside the C-shaped support base, and the arc-shaped rib is movably set in the arc-shaped guide groove. The first C-shaped anti-light leakage plate is located between the bottom surface of the protruding edge and the top surface of the arc-shaped guide protrusion, and the bottom edge of the heat sink is attached to the top surface of the arched surface.
[0059] like Figure 3 As shown in this embodiment, a positioning groove 18 is provided at the bottom edge of the convex edge, and a positioning protrusion 19 is fixed on the top surface of the first C-shaped light-blocking plate; the positioning protrusion is engaged in the positioning groove for positioning. This ensures the ease and stability of installation of the first C-shaped light-blocking plate and prevents it from loosening or falling off.
[0060] The arc shape of its arc rib is the same as that of the arc guide groove, and the length of the arc rib is less than the length of the arc guide groove. Therefore, the arc rib can move within the arc guide groove to achieve corresponding angle adjustment. It can also ensure that the convex edge is close to the arc guide protrusion, ensuring the effectiveness and stability of preventing light leakage. Furthermore, the arc rib and the arc guide groove can also limit the connection between the two to prevent loosening or falling off. During installation, the light guide ring is inserted from the bottom surface of the C-shaped support base and, under the action of external force, the arc rib is slightly deformed and inserted into the arc guide groove.
[0061] like Figure 5 As shown, the top surfaces of the two side arms of the C-shaped support base are provided with limiting arc grooves 10; a ball bearing 11 is fixed to the bottom surface of the heat sink, and the ball bearing is positioned within the limiting arc groove; during use, when the lamp structure rotates on the C-shaped support base to adjust its angle, the ball bearing is positioned within the limiting arc groove, and the resistance between the two achieves the angle adjustment and limitation. The ball bearing is a conventional structure in the prior art, mainly to increase the resistance between the two. When no external force is applied, the ball bearing is positioned within the limiting arc groove to achieve angle positioning. Furthermore, the ball bearing can also be guided and limited within the limiting arc groove to prevent tilting or displacement. Simultaneously, in conjunction with the arc ribs, it ensures the stability of the lamp structure and the C-shaped support base during installation.
[0062] like Figure 1 and Figure 2As shown, the top of each of the symmetrical sides of the second C-shaped light-leakage prevention plate is integrally formed with an angle adjustment limiting protrusion 12; each of the symmetrical sides of the heat sink is provided with two vertical limiting protrusions 13 with a semi-circular cross-section; in use, when the second C-shaped light-leakage prevention plate is connected to the C-shaped support base, the angle adjustment limiting protrusion is located between the two vertical limiting protrusions, and when the lamp structure adjusts its angle relative to the C-shaped support base, it abuts against one of the vertical limiting protrusions to achieve angle limiting. When the lamp structure adjusts its angle on the C-shaped support base, the angle adjustment limiting protrusion will move between the two vertical limiting protrusions and limit the maximum angle.
[0063] like Figure 2 and Figure 6 As shown, a right-angled triangular protrusion 14 is integrally formed on the bottom surface of the end of the arc-shaped guide protrusion; an upwardly protruding abutment protrusion 15 is integrally formed on the symmetrical inner wall of the second C-shaped light-leakage prevention plate; the abutment protrusion is attached to the inclined surface of the right-angled triangular protrusion; a transition protrusion 20 is provided on the outer wall of the light-guiding ring, and the transition protrusion is connected to the opening of the arc-shaped guide protrusion; the arc-shaped edge of the second C-shaped light-leakage prevention plate is close to the outer side of the light-guiding ring and is located below the transition protrusion. The width of the transition protrusion can be set as needed, and the width is smaller than the width of the arc-shaped guide protrusion, with the second C-shaped light-leakage prevention plate located below the transition protrusion. The combination of the two can improve the effectiveness of preventing light leakage.
[0064] like Figure 5 and Figure 7 As shown, in this embodiment, a plurality of elastic top posts 16 are provided on the side wall of the C-shaped support base; an annular groove 17 is provided on the upper part of the inner wall of the face ring; the C-shaped support base is located inside the face ring, and the elastic top posts are locked and limited within the annular groove. Each elastic top post includes a spring and a cylinder. Under the action of the spring, the outer end of the cylinder extends out of the outer surface of the C-shaped support base and is locked into the annular groove for limitation, preventing loosening or detachment.
[0065] Compared with the prior art, the present invention has the following positive effects: In the present invention, the top surface of the C-shaped support base is an arched surface, and a snap-fit strip groove is provided on the symmetrical outer wall of the C-shaped support base; the light leakage prevention structure includes a first C-shaped light leakage prevention plate and a second C-shaped light leakage prevention plate; the first C-shaped light leakage prevention plate and the second C-shaped light leakage prevention plate are respectively attached to the periphery of the lamp structure to prevent light leakage, which is beneficial to improving the effectiveness of light leakage prevention. Furthermore, the lamp structure is attached to the arched surface and moves on the arched surface to achieve angle adjustment. The two achieve surface-to-surface contact. Under the guidance of the arched surface, the tilt angle of the lamp structure relative to the surface ring can be adjusted. Moreover, surface-to-surface contact can also avoid light leakage at the connection point. With the first C-shaped light leakage prevention plate and the second C-shaped light leakage prevention plate, the stability and reliability of light leakage prevention can be guaranteed, solving the technical deficiency of the prior art where spotlights will leak light when the angle is adjusted.
[0066] Furthermore, the first C-shaped light-blocking plate and the second C-shaped light-blocking plate are connected to the C-shaped support base by snap-fit, which facilitates disassembly and maintenance operations, thereby reducing processing costs and improving assembly and maintenance efficiency.
[0067] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.
[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
