Description

Technical Field

[0001] This utility model relates to lighting fixtures, and in particular to a structure for adjusting the direction of a downlight. Background Technology

[0002] Recessed lights are commonly used in modern interior design. They are installed in the ceiling and project light in a specific direction, such as illuminating lettering or decorative paintings on the wall to create the desired ambiance. To ensure the correct direction of the light, users need to remove the recessed light, rotate the reflector used for guiding the light, and then reinstall it on the ceiling. If the direction is still not ideal, repeated removal and adjustment of the recessed light's direction is required, making the entire process extremely cumbersome and inefficient. Utility Model Content

[0003] The purpose of this invention is to provide a downlight adjustment structure that allows for adjustment of the illumination direction without disassembly, thereby reducing the inconvenience of adjustment and improving construction efficiency.

[0004] The downlight adjustment structure of this utility model includes a ring-shaped base, a hollow lamp holder with an open bottom, the bottom of the lamp holder being mounted on the base and connected to a reflector, an LED bead being mounted on the top of the inner side of the lamp holder, an adjustment ring being installed inside the lamp holder, and a rotating cylinder having one end connected to the inner wall of the adjustment ring. The inner wall of the adjustment ring and the outer wall of the rotating cylinder are spherical in shape and fit together. A light guide cup that can transmit light is installed inside the rotating cylinder, with its two ends respectively positioned opposite to the LED bead and the reflector.

[0005] The downlight adjustment structure described in this utility model allows the base to be mounted on the ceiling via a clip or other means, while the lamp holder is concealed within the ceiling. Inside the lamp holder, from top to bottom, are installed LED beads, an adjustment ring, a rotating cylinder, a light guide cup, and a reflector cup. The LED beads face downwards, and the light they emit passes through the light guide cup and then into the reflector cup before illuminating outwards. To adjust the direction of illumination, the user can insert their finger into the reflector cup and rotate the light guide cup. Because the light guide cup and the adjustment ring are connected via a spherical surface, rotating the light guide cup causes it to rotate around the spherical surface, guiding the light emitted by the LED beads to the desired direction, thus achieving light adjustment. Using this downlight adjustment structure, users do not need to disassemble or reassemble the lamp to adjust the light direction, and the operation is extremely simple and quick, effectively improving the convenience of adjustment and construction efficiency.

[0006] Preferably, the inner side of the base has a recessed annular groove along the circumference, and the lamp housing has a positioning hole opposite to the annular groove. A positioning bead and a positioning spring are installed in the positioning hole, and one end of the positioning spring contacts the positioning bead and presses against the annular groove.

[0007] Preferably, a positioning cylinder is installed at the positioning hole, with one end of the positioning cylinder open facing the annular groove and the other end closed, and the positioning bead and positioning spring are installed inside the positioning cylinder.

[0008] Preferably, the joint ring includes a fixed ring and a connecting ring that are detachably connected to each other, and the inner surfaces of the fixed ring and the connecting ring are arc-shaped that transitions along a spherical surface.

[0009] Preferably, the rotating drum includes a rotating drum body with an adjusting ring connected to one end, and a rotating ring detachably connected to the other end of the rotating drum body. A gap is left between the rotating body and the inner wall of the rotating ring, and the edge of the light guide cup is fixed at the gap.

[0010] Preferably, the two ends of the light guide cup are respectively recessed, and the diameter of the recessed part gradually decreases from the outside to the inside.

[0011] Preferably, the inner diameter of the reflector cup gradually increases from top to bottom.

[0012] Preferably, the inner diameter of the rotating ring gradually increases from top to bottom.

[0013] With the above-mentioned downlight adjustment structure, the lighting area of ​​the downlight can be adjusted more conveniently and quickly to achieve the desired lighting effect, and the connection and disassembly of the components can also be made more convenient.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0018] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0019] If the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0020] This utility model proposes a downlight adjustment structure.

[0021] The downlight adjustment structure of this embodiment includes a ring-shaped base 1, a hollow lamp housing 2 with an open bottom, the bottom of the lamp housing is mounted on the base and connected to a reflector cup 3, an LED bead 4 is mounted on the top of the inner side of the lamp housing, an adjustment ring 5 is also installed inside the lamp housing, and a rotating cylinder 6 is connected to the inner wall of the adjustment ring at one end. The inner wall of the adjustment ring and the outer wall of the end of the rotating cylinder are spherical in shape to match each other. A light guide cup 7 that can transmit light is also installed inside the rotating cylinder. The two ends of the light guide cup are respectively arranged opposite to the LED bead and the reflector cup.

[0022] like Figure 1-3 As shown, the base can be mounted on the ceiling using a clip or other means, while the lamp housing is hidden inside the ceiling. Inside the lamp housing, from top to bottom, are installed LED beads, an adjustment ring, a rotating cylinder, a light guide cup, and a reflector cup. The LED beads are positioned downwards, and the light they emit passes through the light guide cup and enters the reflector cup before illuminating outwards. If the direction of illumination needs to be adjusted, the user can insert their finger into the reflector cup and rotate the light guide cup. Because the light guide cup and the adjustment ring are connected by a spherical surface, rotating the light guide cup allows it to rotate around the spherical surface, guiding the light emitted by the LED beads to the desired direction, thus achieving light adjustment.

[0023] The aforementioned downlight adjustment structure has a recessed annular groove on the inner side of the base 1. A positioning hole is provided on the lamp housing 2 opposite to the annular groove. A positioning bead 8 and a positioning spring 9 are installed in the positioning hole. One end of the positioning spring contacts the positioning bead and abuts against the annular groove, thus axially positioning the base and lamp housing while allowing relative circumferential rotation. The user can apply a circumferential rotational force to the reflector cup, thereby utilizing the connection between the reflector cup and the lamp housing to rotate the lamp housing relative to the base. Combined with the rotation of the rotating drum, the lighting effect can be better adjusted. The reflector cup 7 and the lamp housing 2 can be connected by a snap-fit, or... Figure 3As shown, the lamp housing is connected by a thread. When it is necessary to rotate the lamp housing, the reflector cup is rotated in the direction of tightening the thread to drive the lamp housing to rotate. The positioning bead and positioning spring can be directly installed in the positioning hole of the lamp housing, or they can be installed indirectly. For example, a positioning cylinder is installed at the positioning hole. The positioning cylinder is open at one end facing the annular groove and closed at the other end. The positioning bead 8 and positioning spring 9 are installed in the positioning cylinder. This can reduce the manufacturing difficulty of the parts and improve the convenience of assembly and disassembly.

[0024] like Figure 3 As shown, the adjusting ring 5 includes a fixed ring 51 and a connecting ring 52 that are detachably connected to each other. The inner surfaces of the fixed ring and the connecting ring are arc-shaped, transitioning along a spherical surface. Together, they form a spherical surface that mates with the outer wall of the rotating cylinder, thus ensuring the adjustment of the rotating cylinder and facilitating the assembly and disassembly of the components. Similarly, the rotating cylinder 6 includes a rotating cylinder body 61 connected to the adjusting ring 5 at one end, and a rotating ring 62 detachably connected to the other end of the rotating cylinder body. A gap is left between the rotating body and the inner wall of the rotating ring, and the edge of the light guide cup 7 is fixed at the gap, which also facilitates the assembly and disassembly of the light guide cup.

[0025] The aforementioned downlight adjustment structure features a light guide cup 7 with concave ends forming a light guide surface. The diameter of the concave portion gradually decreases from the outside to the inside, creating a trumpet-shaped structure. The inner diameter of the reflector cup 3 is similar to the concave portion at the bottom of the light guide cup, gradually increasing from top to bottom. This allows the light emitted by the LED beads to converge at the top of the light guide cup and then be reflected sequentially from the bottom of the light guide cup and the reflector cup to the desired area, thus achieving the desired lighting effect and reducing light loss. Similarly, a rotating ring 62 is positioned between the light guide cup and the reflector cup. Its inner diameter is similar to the bottom of the light guide cup and the inner wall of the reflector cup, also gradually increasing from top to bottom. This allows the light guide cup, rotating ring, and reflector cup to form a more complete trumpet-shaped reflective surface, better reflecting light.

[0026] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
