[0003] In related technologies, the disassembly and replacement of downlights usually requires the complete removal of the light fixture, which is not only complicated to operate, but also easy to damage the light fixture itself and the mounting base. In addition, the angle adjustment function of downlights is also relatively limited, usually only fine adjustment can be made through the locking point, and 360° free rotation cannot be achieved, which limits the application scenarios of downlights.

Detailed Implementation

[0019] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] In related technologies, the disassembly and replacement of downlights typically requires the complete removal of the entire fixture, which is not only complex to operate but also prone to damaging the fixture itself and the mounting base. For example, repeated disassembly and reassembly can lead to fixture deformation and wear on mounting points, thus affecting the fixture's appearance and lifespan. In addition, the angle adjustment function of existing downlights is also relatively limited, usually only allowing for fine adjustments through locking points, and cannot achieve 360° free rotation, thus restricting the flexible adjustment of the light direction.

[0023] To address the aforementioned issues, this application provides a detachable structure and downlight for a downlight, enabling replacement of the downlight without disassembling the entire light fixture, and the downlight can rotate at all angles, thus improving practicality.

[0024] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] See Figures 1-7 A detachable structure for a downlight, comprising: The outer ring 1 has a recessed portion 2 on its inner wall; the inner ring 3 is detachably disposed inside the outer ring 1 and has at least one hollowed-out mounting portion 4. An elastic element 401 is disposed inside the mounting portion 4, and a limiting element 402 protruding from the elastic element 401 is disposed on the elastic element 401. The limiting element 402 is used to cooperate with the recessed portion 2. When the outer ring 1 and the inner ring 3 are assembled, the limiting element 402 of the elastic element abuts against the inner wall of the recessed portion 2. When the outer ring 1 and the inner ring 3 are disassembled, the elastic element 401 moves away from the recessed portion 2 so that the limiting element 402 moves away from the recessed portion 2.

[0026] Specifically, the recessed part 2 can be a groove structure on the inner wall of the outer ring 1, specifically a continuous annular groove or a recessed pit distributed at intervals, for accommodating the limiting member 402. The mounting part 4 can be a hollow area circumferentially set in the inner ring 3. An elastic member 401 is provided in the mounting part 4. In the mounting part 4, other areas besides the elastic member 401 can form U-shaped openings or rectangular through holes, which can provide deformation space for the elastic member 401.

[0027] Specifically, the elastic element 401 can deform under external force, and the limiting element 402 can be a protrusion at the end of the elastic element 401, which can form a point contact or surface contact fit with the recessed part 2. During assembly, when the inner ring 3 is pushed into the outer ring 1, the elastic element 401 is compressed and undergoes elastic deformation, and the limiting element 402 slides into the recessed part 2 along the inner wall of the outer ring 1 to complete the locking. When disassembling, pressure is applied to the elastic element 401, and the inner and outer rings 1 can be separated after the limiting element 402 comes out of the recessed part 2. The deformation of the elastic element 401 is controlled within the elastic limit of the material, ensuring that it can still return to its initial shape after repeated disassembly and assembly. Through the deformation of the elastic element 401, the inner ring 3 and the outer ring 1 can be quickly disassembled, thereby allowing the light source to be removed more quickly without having to remove the entire downlight from the ceiling and then replace the downlight.

[0028] Furthermore, the inner ring 3 and the outer ring 1 can be manufactured using an integral molding process. The materials for the inner ring 3 and the outer ring 1 can be resin, plastic, etc., and the outer ring 1 can also be made of metals such as iron or aluminum; there are no restrictions here. Furthermore, the elastic element 401 can be installed into the mounting part 4 through another process after the inner ring 3 is manufactured. For example, the elastic element 401 can be made of materials capable of elastic deformation, such as phosphor bronze sheets, spring steel sheets, resin materials, and polymer plastics. The elastic element can also be manufactured with the inner ring 3 using an integral molding process.

[0029] Furthermore, the inner ring 3 (at this time, the mounting part 4 has not yet been installed in the inner ring 3) can be manufactured as a whole first, and then the mounting part 4 can be opened on the inner ring 3.

[0030] Specifically, the diameter of the inner ring 3 is smaller than the diameter of the outer ring 1, so that the inner ring 3 can be installed inside the outer ring 1.

[0031] Specifically, when the limiting member 402 abuts against the recess 2, it can stably match the inner ring 3 with the outer ring 1. By rotating the inner ring 3, the limiting member 402 can move within the recess 2 of the outer ring 1, so that the inner ring 3 can rotate better, and the subsequent lighting component 8 can rotate and irradiate at all angles under the drive of the inner ring 3.

[0032] In one possible implementation, the inner ring 3 is provided with a plurality of mounting parts 4 evenly distributed in the circumferential direction.

[0033] Specifically, uniform distribution in the circumferential direction means that the inner ring 3 is arranged at equal intervals along the circumference. For example, a mounting part 4 is set at fixed angles on the circumference of the inner ring 3. Each mounting part 4 is equipped with an elastic element. The number of mounting parts 4 can be multiple, depending on actual needs, and there is no limit here.

[0034] Specifically, after multiple mounting parts 4 are evenly distributed along the circumference of the inner ring 3, the elastic element 401 in each mounting part 4 can synchronously generate elastic deformation, so that the limiting element 402 uniformly contacts the inner wall of the recess 2 when the outer ring 1 and the inner ring 3 are assembled. This layout makes the contact force between the inner ring 3 and the outer ring 1 evenly distributed in the circumferential direction, avoiding structural deformation due to excessive local force. When disassembly is required, the user can apply force evenly to make multiple elastic elements 401 synchronously detach from the recess 2, thereby reducing the force required for single-point operation.

[0035] In one possible implementation, multiple mounting parts 4 are symmetrically arranged on the inner ring 3.

[0036] Specifically, the symmetrical arrangement can be a mirror image distribution along the central axis of the inner ring 3's circumference. For example, four sets of mounting parts 4 can be arranged at 90-degree intervals. When the mounting parts 4 are symmetrically arranged along the axis of the inner ring 3, the deformation directions of the elastic elements 401 are complementary. When a disassembly force is applied, the symmetrically distributed elastic elements 401 undergo coordinated deformation, causing the limiting elements 402 to simultaneously detach from the recessed portion 2 of the outer ring 1. This symmetrical layout allows the disassembly operation to proceed without a specific force angle; applying tension in any direction can trigger the synchronous action of the symmetrically positioned elastic elements 401. During assembly, the symmetrically arranged limiting elements 402 can simultaneously form multiple points of contact with the recessed portion 2 of the outer ring 1, avoiding the off-center loading phenomenon caused by unilateral contact.

[0037] In one possible implementation, the limiting member 402 is spherical in shape and can slide within the recess 2.

[0038] Specifically, the spherical shape of the limiting member 402 means that the limiting member 402 has a spherical structure. The spherical structure allows the limiting member 402 to slide better within the recess 2, reducing the frictional resistance with the inner wall of the recess 2. The recess 2 can be a sliding groove. When the inner ring 3 is assembled with the outer ring 1, the spherical limiting member 402 is embedded in the sliding groove of the recess 2, and the elastic force of the elastic member 401 keeps the limiting member 402 in contact with the sliding groove. When it is necessary to adjust the relative angle between the inner ring 3 and the outer ring 1, the inner ring 3 can rotate around the axis of the outer ring 1. At this time, the spherical limiting member 402 rolls or slides along the sliding groove to achieve multi-angle adjustment. During disassembly, the elastic member 401 is deformed under pressure, causing the limiting member 402 to disengage from the sliding groove, and the inner ring 3 can be pulled out directly.

[0039] In one possible implementation, a fastener 5 is also included, and a first through hole 403 is provided on the inner ring 3, and the fastener 5 can be inserted into the first through hole 403.

[0040] Specifically, the fastener 5 refers to the fastening part used to connect the inner ring 3 with other components. It can be a screw, pin, or snap-fit ​​structure. The first through hole 403 refers to the through hole opened on the surface of the inner ring 3. It can be a circular, square, or polygonal hole structure. Its function is to provide a path for the fastener 5 to achieve the positioning function. Through the cooperation of the fastener 5 and the through hole, the inner ring 3 can be tightly connected with other components. The fastener 5 can be a 10-15 mm self-tapping screw with a diameter matching the through hole.

[0041] Specifically, the inner ring 3 is detachably connected to the fastener 5 through the first through hole 403. During assembly, the fastener 5 passes through the first through hole 403 of the inner ring 3 and is fixed to the external components. For example, when the inner ring 3 needs to be connected to the middle ring 6, the fastener 5 can be inserted into the through holes of both to form a constraint. When disassembling, the connection can be released simply by pulling the fastener 5 out of the through hole.

[0042] In one possible implementation, the middle ring 6 is provided with a second through hole 601 that matches the first through hole 403, and the fastener 5 can be inserted into the first through hole 403 and the second through hole 601 so that the inner ring 3 and the middle ring 6 are fixedly installed.

[0043] Specifically, the second through hole 601 refers to a through hole structure opened on the surface of the middle ring 6, whose position and size completely correspond to the first through hole 403 of the inner ring 3. For example, it can be a circular hole with a diameter ranging from 2 to 5 mm, formed by machining. During assembly, the first through hole 403 of the inner ring 3 and the second through hole 601 of the middle ring 6 are aligned by rotation or translation. Then, the fastener 5 is inserted into the through holes of both. The insertion of the fastener 5 forms a rigid connection between the inner ring 3 and the middle ring 6, preventing relative displacement.

[0044] In one possible implementation, at least one mounting element 101 is provided on the outer ring 1.

[0045] Specifically, the mounting component 101 refers to the component used to fix or connect the outer ring 1 to other external structures, such as a spring clip. The mounting component 101 can provide support between the outer ring 1 and the external support structure, preventing the outer ring 1 from shifting due to uneven force after assembly. It can embed the downlight formed by the outer ring 1 into the ceiling. For example, when the mounting component 101 is a snap-on structure, the protruding part of the snap can be embedded into the pre-reserved mounting hole in the ceiling, generating a fixing force through elastic deformation. When disassembly is required, the lock can be released by pressing the release end of the snap, which allows the outer ring 1 to be quickly installed or removed without the aid of auxiliary tools.

[0046] The detachable structure of this application is mainly used in recessed lighting fixtures such as downlights, spotlights, and ceiling lights. Specifically, the main body of the lighting fixture is fixed to the inner ring 3. The main body of the lighting fixture can rotate relative to the outer ring 1 under the rotation of the inner ring 3, and the rotation angle can be a full-angle rotation.

[0047] This application discloses a detachable structure for a downlight, comprising: an outer ring 1, the inner wall of which has a recess 2; and an inner ring 3, detachably disposed within the outer ring 1, the inner ring 3 having at least one hollow mounting portion 4, an elastic element 401 disposed within the mounting portion 4, and a limiting element 402 protruding from the elastic element 401, the limiting element 402 cooperating with the recess 2; when the outer ring 1 and the inner ring 3 are assembled, the limiting element 402 abuts against the inner wall of the recess 2; when the outer ring 1 and the inner ring 3 are disassembled, the elastic element 401 moves away from the recess 2, so that the limiting element 402 moves away from the recess 2, enabling the downlight to be replaced without disassembling the entire lamp, and the downlight can rotate at all angles, improving practicality.

[0048] Another aspect of this application provides a downlight, including the detachable structure for the downlight, a retaining ring 7, and a lighting component 8 as described above. The lighting component 8, retaining ring 7, middle ring 6, inner ring 3, and outer ring 1 are nested together from the inside out. This downlight can be used in ceilings, RVs, and other scenarios, without limitation.

[0049] Specifically, the retaining ring 7 refers to the ring-shaped component used to fix the lighting assembly 8, which can be a plastic part with an elastic buckle. The lighting assembly 8 refers to the lighting module containing the light source, which can be composed of a heat sink 801, a lamp cup 802, a light source plate 803 and a lens 804.

[0050] Specifically, the lighting component 8 is fixed to the innermost layer by the retaining ring 7. The retaining ring 7 is connected to the middle ring 6 via an elastic buckle. The middle ring 6 is connected to the outer ring 1 via screws or snap-fit ​​components. The inner ring 3 is fitted with the recessed part 2 of the outer ring 1 via a limiting component 402 to form a detachable structure. During installation, the lighting component 8 is first inserted into the retaining ring 7, which is then snapped into the middle ring 6 to form a fixed connection. The middle ring 6 and the inner ring 3 are connected by the fixing component 5, and the inner ring 3 and the outer ring 1 are connected by the mounting part 4, forming a stable, nested structure. During disassembly, only the limiting fit between the inner ring 3 and the outer ring 1 needs to be released, that is, the lighting component 8 is separated from the outer ring 1. Then, other components are separated layer by layer, which makes it easier to disassemble the lighting component 8. In related technologies, the outer ring 1 also needs to be removed from the ceiling before the lighting component 8 can be separated, which is too cumbersome and can easily damage the ceiling, reducing the lifespan of the light fixture.

[0051] In one possible implementation, the lighting assembly 8 includes a heat sink 801, a lamp cup 802, a light source plate 803, and a lens 804. The lamp cup 802 is installed at the lower end of the heat sink 801, the light source plate 803 is disposed inside the lamp cup 802, and the lens 804 is located at the front end of the light source plate 803.

[0052] Specifically, a switch can be installed at the upper end of the heat sink 801 to adjust the color temperature of the lighting component 8. The heat sink 801 can be a metal component for conducting and dissipating heat generated by the light source board 803. The lamp cup 802 refers to a cup-shaped container for housing the light source board 803, such as an aluminum shell with reflective material coated on the inner wall, which improves light efficiency by reflecting light. The light source board 803 is a circuit board that carries the light-emitting element and can reduce thermal resistance by using high thermal conductivity materials. The lens 804 is an optical element for controlling the light distribution, such as a Fresnel lens 804 made of polycarbonate injection molding, which controls the beam angle by optimizing curvature. The lamp cup 802 is fixed to the bottom opening of the heat sink 801 by threads or clips to form a sealed cavity. The light source board 803 is attached to the inner bottom surface of the lamp cup 802 by a thermally conductive adhesive layer to ensure that heat is transferred to the heat sink 801. The lens 804 is mounted in the front opening of the lamp cup 802 through an annular slot, and maintains a preset distance from the light source board 803 to form a collimated light path. In one possible implementation, the illumination assembly 8 further includes reflective paper 805, which is attached to the outer wall of the lens 804.

[0053] Specifically, reflective paper 805 is a thin film material with light reflection function, such as aluminized polyester film or metallized PET material. Its surface is embossed to enhance the diffuse reflection effect. In the lighting assembly 8, it is used to redirect the light scattered inside the lens 804 to the target area. Reflective paper 805 is attached to the outer wall of the lens 804. Reflective paper 805 reflects the light emitted by the light source plate 803 to improve the brightness and lumen of the lamp.

[0054] The above are merely specific embodiments of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
