If a 360-degree adjustment in various directions, as well as fine-tuning the angle, is required, the mounting position of the recessed luminaire must be changed to achieve the desired angle. Previously, the entire recessed luminaire had to be removed for replacement. Furthermore, each disassembly and reassembly causes wear and tear on the luminaire body and the wall, shortening its lifespan and leading to product wear and tear from repeated disassembly.

By snapping and releasing the elastic limiting assembly, quick assembly and disassembly of the center and outer rings is achieved. When replacing the lighting assembly of the recessed luminaire, it is not necessary to remove the entire outer ring from the ceiling. Simply by actuating the elastic element, the inner part containing the lighting assembly can be removed as a whole.

[0012] Lighting fixtures are indispensable in everyday life. Generally, fixtures must be permanently connected to electrical wiring so that an external power source can supply the fixture's internal light source. With the related technology, adjusting the light direction of a recessed fixture is only possible by rotating both sides to achieve a forward and backward swivel. If 360-degree adjustment in various directions, as well as fine-tuning the angle, is required, the mounting position of the recessed fixture must be changed to achieve the desired angle. Previously, the entire recessed fixture had to be removed for replacement. Furthermore, each disassembly and reassembly causes wear and tear on the fixture body and the wall, shortening its lifespan and leading to product wear and tear from repeated disassembly.

[0013] In light of the aforementioned problems, embodiments of the present application provide a quick-release structure for a recessed luminaire. By snapping and releasing an elastic limiting assembly, rapid assembly and disassembly of the central and outer rings is achieved. When replacing the lighting assembly of the recessed luminaire, it is not necessary to remove the entire outer ring from the ceiling. Simply by actuating the elastic element, the inner part containing the lighting assembly can be removed as a whole. This significantly simplifies the maintenance process and prevents damage to the outer ring and the ceiling caused by repeated disassembly. Simultaneously, the central and outer rings can rotate relative to each other, enabling the recessed luminaire to achieve a 360-degree angled lighting adjustment, thus meeting complex lighting requirements.

[0014] The technical solution of the embodiments of the present application is described in detail below in conjunction with the attached drawings.

[0015] See Fig. 1 to Fig.3. A quick-disassembly structure for a recessed luminaire comprises: an outer ring 1, wherein an annular boundary track 2 is formed on the inner wall of the outer ring 1; a central ring 3, wherein the central ring 3 is disassemblably arranged in the outer ring 1; an elastic boundary assembly 4, which is arranged on the central ring 3, wherein the elastic boundary assembly 4 comprises an elastic element 401 and a boundary element 402 arranged on the elastic element 401, wherein the boundary element 402 serves to interact with the annular boundary track 2.When the outer ring 1 and the middle ring 3 are mounted, the limiting element 402 of the elastic element 401 snaps into the annular limiting track 2; when the outer ring 1 and the middle ring 3 are disassembled, the elastic element 401 moves in a direction away from the annular limiting track 2 in order to remove the limiting element 402 from the annular limiting track 2.

[0016] Specifically, the annular limiting track 2 can be arranged circumferentially around the inner wall of the outer ring and serves to snap into the limiting element 402. The assembly section 404 can be a hollow area arranged circumferentially on the central ring 3. The elastic element 401 is arranged in the assembly section 404. In addition to the elastic element 401, a U-shaped opening or a rectangular through-hole can be formed in the other areas of the assembly section 404, which can provide a deformation space for the elastic element 401. The elastic element 401 can be deformed under the influence of an external force. The limiting element 402 can be a projecting structure arranged at the end of the elastic element 401, which is capable of forming a point-contact or surface-contact fit relationship with the annular limiting track 2.During the assembly process, when the center ring 3 is pushed into the outer ring 1, the elastic element 401 is elastically deformed by pressure, and the limiting element 402 engages along the inner wall of the outer ring 1 in the annular limiting track 2 to complete the locking mechanism. During disassembly, pressure is applied to the elastic element 401, and after the limiting element 402 is released from the engagement with the annular limiting track 2, the center ring 3 and the outer ring 1 can be separated. The deformation of the elastic element 401 is controlled within the elastic limit of the material to ensure that it can return to its original shape after repeated disassembly and assembly.The deformation of the elastic element 401 allows the middle ring 3 and the outer ring 1 to be quickly disassembled, which allows the light source to be removed more quickly without having to remove the entire recessed light fixture from the ceiling to replace the recessed light fixture.

[0017] Furthermore, the center ring 3 and the outer ring 1 can be manufactured by a one-piece molding process. The material of the center ring 3 and the outer ring 1 can be resin, plastic, etc. The outer ring 1 can also be made of metal such as iron or aluminum; this is not limited here. Furthermore, the elastic element 401 can be installed in assembly section 404 after the completion of the center ring 3 by a different process. For example, the elastic element 401 can be made of phosphor bronze sheet, spring steel sheet, resin material, high polymer plastic, or other materials that can undergo elastic deformation. The elastic element can also be manufactured together with the center ring 3 by a one-piece molding process. The outer ring 1 is made of die-cast aluminum alloy, and the center ring 3 is injection-molded from engineering plastic.It is understood that other materials with sufficient structural strength can also be used to manufacture the outer ring 1 and / or the middle ring 3.

[0018] Furthermore, the middle ring 3 (at this point, no assembly section 404 is yet provided in the middle ring 3) can first be manufactured as a whole, and then the assembly section 404 in the middle ring 3 is opened. Specifically, the diameter of the middle ring 3 is smaller than the diameter of the outer ring 1 so that the middle ring 3 can be mounted in the outer ring 1.

[0019] In one possible embodiment, a mounting section 404 for receiving the elastic limiting assembly 4 is formed on the central ring 3. In one possible embodiment, the mounting section 404 is a hollow structure. In one possible embodiment, the annular limiting track 2 is a projection or a groove that extends circumferentially along the inner wall of the outer ring 1.

[0020] In one possible embodiment, the number of elastic limiting assemblies 4 is multiple, and they are distributed uniformly or symmetrically along the circumferential direction of the central ring 3. In another possible embodiment, stepped limiting points 9 are formed on the inner wall of the outer ring 1, wherein the stepped limiting points 9 are located on one side of the annular limiting track 2. Specifically, the stepped limiting points 9 can be arranged circumferentially around the inner wall of the outer ring 1. After the outer ring 1 and the central ring 3 have reached their assembled state, the stepped limiting points 9 can abut one end of the central ring 3, so that the end of the outer ring 1 and the end of the central ring 3 can lie on the same horizontal line.

[0021] In one possible embodiment, several mounting sections 404 are arranged evenly distributed around the circumference of the central ring 3. Specifically, the even distribution around the circumference means that they are arranged at equal intervals along the circumference of the ring-shaped structure of the central ring 3; for example, a mounting section 404 is arranged at each fixed angle on the circumference of the central ring 3. An elastic element is arranged in each mounting section 404. The number of mounting sections 404 can be multiple and can be determined according to actual requirements; this is not limited here.Specifically, after several assembly sections 404 have been evenly distributed along the circumference of the central ring 3, the elastic elements 401 in each assembly section 404 can synchronously generate an elastic deformation, causing the limiting elements 402 to snap into the annular limiting track during the assembly of the outer ring 1 and the central ring 3. This arrangement ensures that the contact force between the central ring 3 and the outer ring 1 is evenly distributed in the circumferential direction, thus preventing structural deformation due to excessive local stress. When disassembly is required, the user can apply a uniform force to cause several elastic elements 401 to synchronously detach from the annular limiting track 2, thereby reducing the force required for actuation at a single point.

[0022] In one possible embodiment, several mounting sections 404 are arranged symmetrically on the central ring. Specifically, the symmetrical arrangement can be a mirror-image distribution in the circumferential direction of the central ring 3 with the central axis as a reference. For example, four groups of mounting sections 404 are arranged at 90-degree intervals. If the mounting sections 404 are arranged symmetrically along the axis of the central ring 3, the deformation directions of the elastic elements 401 form a complementary relationship. When a disassembly force is applied, the symmetrically distributed elastic elements 401 generate a synergistic deformation, causing the limiting elements 402 to detach synchronously from the annular limiting track 2 of the outer ring 1.This symmetrical arrangement eliminates the need to maintain a specific force angle during disassembly; a tensile force in any direction can cause the symmetrically positioned elastic elements 401 to move synchronously. During the assembly process, the symmetrically arranged limiting elements 402 can simultaneously form multiple contact points with the annular limiting track 2 of the outer ring 1, thus avoiding the phenomenon of oblique loading due to one-sided contact.

[0023] In one possible embodiment, the shape of the limiting element 402 is spherical, and the limiting element 402 can slide along the longitudinal direction of the annular limiting track 2. Specifically, the limiting element 402 being spherical means that its outer shape has a spherical structure. This spherical structure allows the limiting element 402 to slide more easily along the longitudinal direction of the annular limiting track 2, thereby reducing the frictional resistance with the annular limiting track 2. When the central ring 3 and the outer ring 1 are mounted, the spherical limiting element 402 engages in the annular limiting track 2, with the contact between the limiting element 402 and the annular limiting track 2 being maintained by the spring force of the elastic element 401.During the disassembly process, the elastic element 401 deforms under pressure, thereby releasing the locked state of the limiting element 402 with the annular limiting track 2 and allowing the central ring 3 to be pulled out directly.

[0024] In one possible embodiment, fastening elements 5 are further included, and a first through-hole 403 is provided in the central ring 3, wherein the fastening element 5 can be inserted into the first through-hole 403. Specifically, the fastening element 5 refers to a connecting part used to connect the central ring 3 to other components. It can be a screw, a pin, or a snap-fit ​​mechanism. The first through-hole 403 is a through hole that is open in the surface of the central ring 3. Specifically, a round, square, or polygonal hole structure can be used. Its function is to provide an insertion path for the fastening element 5 to achieve a positioning function. Through the interaction of the fastening element 5 and the through-hole, the central ring 3 can be firmly connected to other parts.The fastener 5 can be a self-tapping screw with a diameter of 10-15 millimeters, matching the through-hole. Specifically, the center ring 3 forms a detachable connection through the first through-hole 403 and the fastener 5. During the assembly process, the fastener 5 passes through the first through-hole 403 of the center ring 3 and forms a connection with an external component. For example, if the center ring 3 needs to be connected to the inner ring 6, the fastener 5 can be inserted simultaneously into the through-holes of both to create a bond. Disassembly simply requires pulling the fastener 5 out of the through-hole to release the connection.

[0025] In one possible embodiment, an inner ring 6 is further included, wherein a second through-hole 601 is provided in the inner ring 6, which aligns with the first through-hole 403. The fastening element 5 can be inserted into the first through-hole 403 and the second through-hole 601 to securely mount the inner ring 6 and the center ring 3. Specifically, the second through-hole 601 refers to a through-hole structure that is open in the surface of the inner ring 6. Its position and dimensions correspond exactly to the first through-hole 403 of the center ring 3. For example, a round hole with a diameter in the range of 2–5 millimeters, formed by machining processes, can be used.During the assembly process, the first through-hole 403 of the center ring 3 and the second through-hole 601 of the inner ring 6 are positioned by rotational or sliding operations, and then the fastening element 5 is inserted into the through-holes of both. The insertion of the fastening element 5 creates a rigid connection between the center ring 3 and the inner ring 6, thus preventing any relative displacement.

[0026] The quick-release mechanism of the present application is primarily used in recessed luminaires such as recessed lights, spotlights, and ceiling lights. Specifically, the main part of the luminaire is fixed to the inner ring 6. The main part of the luminaire can rotate relative to the outer ring 1 along with the rotation of the inner ring 6, with the rotation angle being a full angular rotation.

[0027] The present application provides a structure for quick disassembly of a recessed luminaire, comprising: an outer ring, wherein an annular boundary track is formed on the inner wall of the outer ring, the annular boundary track projecting from the inner wall of the outer ring; a middle ring, wherein the middle ring is disassemblably arranged in the outer ring, wherein at least one hollow mounting section is provided on the middle ring, wherein an elastic element is arranged in the mounting section, wherein a boundary element is arranged on the elastic element, the boundary element projecting from the elastic element, the boundary element serving to interact with the annular boundary track; when the outer ring and the middle ring are mounted, the boundary element of the elastic element snaps into the annular boundary track;When the outer and middle rings are removed, the elastic element moves away from the annular boundary track, thus removing the boundary element from the annular boundary track. In this way, the recessed light can be replaced without disassembling the entire light fixture, and the recessed light can be rotated at any angle, improving practicality.

[0028] Operating principle: In the quick-release structure for a recessed luminaire of the present application, an annular limiting track is formed in the upper front part of the outer ring. The annular limiting track can be designed as a limiting rib. The annular limiting track projects from the interior of the outer ring. The stepped limiting points can be stair-shaped limiting points. The stepped limiting points serve to prevent the middle ring from extending beyond the plane of the outer ring during assembly due to excessive force, which would impair the aesthetics and design. When the outer ring and middle ring are properly assembled, the middle ring only needs to be pressed in slightly to snap into the outer ring; at this point, the limiting element engages with the annular limiting track.If disassembly is required, the center ring only needs to be pushed in the opposite direction to release the snap-fit ​​state between the limiting element and the annular limiting track, thereby releasing the assembly of the center ring and outer ring.

[0029] In another aspect of the present application, a recessed luminaire is provided, comprising the quick-disassembly structure described above for a recessed luminaire, a clamping ring 7, and a lighting assembly 8. The lighting assembly 8, the clamping ring 7, the inner ring 6, the middle ring 3, and the outer ring 1 are mounted sequentially nested within one another, from the inside out. The recessed luminaire can be used in scenarios such as ceilings, motorhomes, etc.; this is not limited here. Specifically, the clamping ring 7 is an annular part used to secure the lighting assembly 8. It can be implemented as a plastic part with elastic snap fasteners. The lighting assembly 8 is a lighting module containing a light source and can consist of a heat sink, a lamp housing, a light source circuit board, and a plate.Specifically, the lighting assembly 8 is secured in the innermost layer by the clamping ring 7. The clamping ring 7 is connected to the inner ring 6 by elastic snap fasteners. The inner ring 6 is connected to the outer ring 1 by screws or snap elements. The middle ring 3, through the interaction of the limiting element 402 with the annular limiting track 2 of the outer ring 1, forms a structure for quick disassembly. During assembly, the lighting assembly 8 is first embedded in the clamping ring 7. The clamping ring 7 snaps into the inner ring 6 to form a secure connection. The inner ring 6 and the middle ring 3 are connected by fasteners 5, and the middle ring 3 and the outer ring 1 are connected by the assembly section 404, thus forming a stable, layered structure. During disassembly, only the limiting fit between the middle ring 3 and the outer ring 1 needs to be released.The lighting assembly 8 is separated from the outer ring 1, and then the other components are separated layer by layer. This allows for easier disassembly of the lighting assembly 8. With the previous technique, the outer ring 1 had to be removed from the ceiling first before the lighting assembly 8 could be separated. This method is too cumbersome and can easily damage the ceiling, thus reducing the lifespan of the light fixture.

[0030] In one possible embodiment, the lighting assembly 8 comprises a heat sink, a lamp cup, a light source circuit board, and a plate. The lamp cup is mounted at the lower end of the heat sink, the light source circuit board is arranged within the lamp cup, and the plate is located at the front end of the light source circuit board. Specifically, a switch may be provided at the upper end of the heat sink for adjusting the color temperature of the lighting assembly 8. The heat sink may be a metal component that serves to conduct and dissipate the heat generated by the light source circuit board. The lamp cup is a cup-shaped container for receiving the light source circuit board, for example, an aluminum housing whose inner wall is coated with reflective material to increase the luminous efficacy by reflecting light rays.The light source board is a circuit substrate that supports the light-emitting elements and can reduce thermal resistance through the use of highly thermally conductive materials. The board is an optical element used to control the light distribution; for example, a Fresnel plate made of injection-molded polycarbonate can be used to control the beam angle by optimizing its curvature. The lamp cup is attached to the open end of the heat sink's base by threads or a snap-fit ​​connection to create a sealed cavity. The light source board is bonded to the base inside the lamp cup using a thermally conductive adhesive to ensure heat transfer to the heat sink. The board is inserted into the opening at the front end of the lamp cup via an annular locking groove and maintains a preset distance from the light source board to create a collimated light path.

[0031] In one possible embodiment, the lighting assembly 8 further comprises reflective paper, the reflective paper being in contact with the outer wall of the plate. Specifically, the reflective paper is a thin film material with light-reflecting properties, for example, an aluminized polyester film or metallized PET material. Its surface has been embossed to enhance the diffuse reflection effect. In the lighting assembly 8, it is used to redirect the light scattered inside the plate onto the target area. Reflective paper is adhered to the outer wall of the plate. The reflective paper reflects the light emitted by the light source board to increase the brightness and lumen output of the luminaire.
