Technical Field
[0001] This invention relates to the field of lighting technology, and more specifically, to an easy-to-install recessed lighting fixture. Background Technology
[0002] Recessed lighting fixtures are popular with consumers due to their novel structure and adjustable light angle. Most current recessed lighting fixtures are installed in the ceiling. There are various installation methods, some using torsion springs, which require high-quality springs (too loose to support the fixture, too tight to damage the ceiling); others using blades, which can damage the ceiling. Furthermore, due to varying ceiling thicknesses, current recessed lighting fixtures are not suitable for all types of ceilings, making installation and disassembly inconvenient. For example, a current technology discloses a recessed lighting installation structure including a light fixture body, a lamp holder assembly, a spring, and an adjusting screw. The light fixture body has a movable groove, and the spring can move relative to the groove. The spring includes a mounting part, a bending part, and a snap-fit part connected in sequence. The mounting part has a first screw hole and is located inside the light fixture body. The snap-fit part snaps into the inner wall of the light fixture body, and the bending part is located outside the light fixture body with its bottom end abutting against the top surface of the ceiling. The adjusting screw passes through the first screw hole and is screwed into the light fixture body. To adapt to different ceiling thicknesses, when the ceiling is thin, rotating the adjusting screw lowers the height of the spring clip so that the bottom end of the bent part abuts against the top surface of the ceiling; when the ceiling is thick, rotating the adjusting screw raises the height of the spring clip so that the bottom end of the bent part always abuts against the top surface of the ceiling, thus enhancing the stability of the recessed light. However, it cannot automatically adapt to different ceiling thicknesses, and external tools are still needed to turn the screw during adjustment, which is inconvenient to use at certain heights and makes the operation relatively complicated. Summary of the Invention
[0003] To overcome the problems mentioned in the background art, such as the inability to automatically adapt to different ceiling thicknesses, the need for external tools and screw tightening during adjustment, and the inconvenience and complexity of use at certain heights, this invention provides an easily installable recessed lighting fixture. This invention can accommodate ceilings of varying thicknesses and is easier to install and disassemble.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an easy-to-install recessed lamp, a lamp body and a mounting assembly, the mounting assembly including a mounting surface ring, one end of the mounting surface ring having a connecting part, the connecting part being connected to the lamp body, characterized in that it further includes a telescopic assembly and a mounting spring, the mounting spring being disposed on the outer side wall of the mounting surface ring, the telescopic assembly being able to extend from the mounting surface ring and push the mounting spring to move away from the mounting surface ring.
[0005] Furthermore, the telescopic assembly includes a cam ring and a cam actuator. The cam ring is disposed inside the mounting surface ring near the end of the connecting portion. The cam ring is rotatably connected to the inner wall of the mounting surface ring. A actuator hole is also provided on the opposite side wall of the mounting surface ring. The cam actuator is movably inserted through the actuator hole. One end of the cam actuator is always in contact with the outer wall of the cam ring, and the other end is always in contact with the end of the mounting spring near the connecting portion.
[0006] Preferably, the end face of the cam actuator is T-shaped or I-shaped, and the actuator hole is a T-shaped hole or I-shaped hole that matches the cam actuator.
[0007] Furthermore, the mounting spring includes a connecting piece, an expansion piece, and a U-shaped connecting portion. The length of the expansion piece is greater than the length of the connecting piece. One end of the connecting piece near the connecting portion is connected to the outer wall of the mounting surface ring. The end of the expansion piece near the connecting portion is always in contact with the cam actuator. The other end of the connecting piece is connected to the other end of the expansion piece through the U-shaped connecting portion.
[0008] Furthermore, a first threaded connection hole is provided at one end of the connecting piece near the connecting part, and a bolt is provided in the first threaded connection hole. A second threaded connection hole is provided on the outer side wall of the mounting surface ring at a position corresponding to the first threaded connection hole. The bolt is threadedly connected to both the first threaded connection hole and the second threaded connection hole.
[0009] Furthermore, the angle between the expansion piece and the outer side wall of the mounting surface ring ranges from 0 to 45°.
[0010] Preferably, the mounting spring is made of stainless steel.
[0011] Furthermore, the cam ring includes an inner ring body and a cover body. The cover body is sleeved on the circumferential outer wall of the inner ring body. The two opposite outer walls of the inner ring body are respectively provided with abutting blades for abutting against the mounting spring. The outer diameter of the abutting blades increases in the same direction.
[0012] Furthermore, a handle is connected to the inner wall of the inner ring body. The handle is arc-shaped, and the inner wall of the inner ring body is also provided with a groove that matches the handle. The two ends of the handle are respectively engaged in the groove.
[0013] Furthermore, the mounting ring has an inner boss on the side of the cam ring opposite to the connecting part, and the surface of the inner boss has a serrated groove. The surface of the cover near the serrated groove also has a rib that matches the serrated groove.
[0014] Compared with existing technologies, the beneficial effects are:
[0015] This invention utilizes the interaction of a cam ring, a cam actuator, and a mounting spring. The rotation of the cam ring drives the cam actuator to move outward, which in turn causes the mounting spring to expand outward, making the mounting spring form an inverted V-shape. This spring is then locked into the ceiling, adapting to different ceiling thicknesses and having low requirements for the width of the ceiling holes. Installation and disassembly do not require additional tools, making operation more convenient and enabling quick installation and disassembly. The installation is stable and reliable, the structure is relatively simple, and the manufacturing cost is lower. Furthermore, this invention incorporates a limiting design at the position of the cam ring and the mounting surface ring to prevent loosening after installation. Attached Figure Description

[0030] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:
[0031] Example 1
[0032] like Figures 1 to 3 As shown, this is an easy-to-install recessed lighting fixture, including a lamp body 20 and mounting components, such as... Figures 4 to 6As shown, the mounting assembly includes a mounting ring 1 and a reflector 6. One end of the mounting ring 1 is provided with a connecting portion 101, which is rotatably connected to the lamp body 20. In this embodiment, the connecting portion 101 and the lamp body 20 are rotatably connected. In other embodiments, the connecting portion 101 and the lamp body 20 may also be configured to be non-rotatably connected. The mounting assembly in this embodiment also includes a telescopic component and a mounting spring 3. The mounting spring 3 is disposed on the outer wall of the mounting ring 1. The telescopic component can extend from inside the mounting ring 1 and push the mounting spring 3 to move away from the mounting ring 1. The telescopic assembly in this embodiment includes a cam ring 2 and a cam actuator 5. The cam ring 2 is disposed inside the mounting surface ring 1 near one end of the connecting portion 101, and the reflector cup 6 is embedded inside the mounting surface ring 1 from the other end. The cam ring 2 is rotatably connected to the inner wall of the mounting surface ring 1. A actuator hole 8 is also provided on the opposite side wall of the mounting surface ring 1, and the cam actuator 5 is movably inserted through the actuator hole 8. One end of the cam actuator 5 always abuts against the outer wall of the cam ring 2, and the other end always abuts against the end of the mounting spring 3 near the connecting portion 101. In other embodiments, the telescopic assembly can also be other structures capable of pushing the mounting spring outward. The lamp body 20 in this embodiment is similar to the existing lamp body structure. The lamp body 20 mainly includes a heat sink 22, a COB light source 23, a light source fastener 24, a lens 25, an anti-glare cylinder 26, and a heat sink cover 27. The COB light source 23 is installed inside the heat sink 22 through the light source fastener 24. The light-incident side of the lens 25 is connected to the COB light source 23. One end of the anti-glare cylinder 26 is connected to the light-outceasing side of the lens 25, and the other end passes through the top of the heat sink cover 33 and the mounting ring 1 and is connected to the light inlet of the reflector cup 6. The entire lamp body 20 is rotatably connected to the connecting part 101 on the mounting ring through the connecting position on the heat sink bracket 21 to form the entire recessed lamp.
[0033] like Figure 8As shown, the mounting spring 3 includes a connecting piece 31, an expansion piece 32, and a U-shaped connecting part 33. The length of the expansion piece 32 is greater than the length of the connecting piece 31. One end of the connecting piece 31 near the connecting part 101 is connected to the outer wall of the mounting surface ring 1. One end of the expansion piece 32 near the connecting part 101 is always in contact with the cam actuator 5. The other end of the connecting piece 31 is connected to the other end of the expansion piece through the U-shaped connecting part 33. A first threaded connection hole 34 is provided at one end of the connecting piece 31 near the connecting part 101. A bolt 7 is provided in the first threaded connection hole 34. A second threaded connection hole is provided at the position corresponding to the first threaded connection hole 34 on the outer wall of the mounting surface ring 1. The bolt 7 is threadedly connected to both the first threaded connection hole 34 and the second threaded connection hole. The connecting piece 31 is set close to the outer wall of the mounting surface ring 1 and is basically parallel to the axis of the mounting surface ring 1. When the cam actuator 5 does not push the expansion piece 32 outward, the connecting piece 31 and the expansion piece 32 are basically parallel, and the expansion piece 32 does not expand outward, which facilitates the insertion and removal of the entire mounting surface ring 1 into the ceiling hole; Reference Figure 4 and Figure 7 When the cam actuator 5 pushes the expansion piece 32 outward under the rotational abutment of the cam ring 2, the overall outer diameter of the mounting structure expands, allowing it to be locked inside the ceiling hole. When the recessed light fixture needs to be removed, the cam ring 2 is rotated back, and the outer diameter of the contact part between the cam ring 2 and the cam actuator 5 gradually decreases, gradually reducing the holding force on the cam actuator 5. Under the elastic restoring force of the expansion piece 32 on the mounting spring 3, the cam actuator 5 gradually moves along the actuator hole 8 into the mounting surface ring 1, achieving reset. The expansion piece 32 returns to its initial non-elastic state, at which point the mounting structure can be removed from the ceiling hole.
[0034] The end face of the cam actuator 5 is T-shaped, and the actuator hole 8 is a T-shaped hole that matches the cam actuator 5. The angle between the expansion piece 32 and the outer wall of the mounting surface ring 1 ranges from 0 to 45°, meaning that the expansion piece 32 can expand outward to a maximum angle of about 45°. Generally, adjusting it to about 30° is sufficient for installation at the upper limit of the ceiling. The cam actuator 5 has a straight structure with a T-shaped end face, and the shape of the actuator hole 8 matches it. Both the actuator hole 8 and the cam actuator 5 are T-shaped, making the sliding more stable. Furthermore, the forces on both ends of the cam actuator 5, the cam ring 2, and the mounting spring 3 are also more stable.
[0035] The mounting spring 3 is made of stainless steel, resulting in a longer service life; Figure 7 and 10As shown, the cam ring 2 includes an inner ring body 201 and a cover body 202. The cover body 202 is fitted onto the circumferential outer wall of the inner ring body 201. Abutment blades 203 for abutting against mounting springs are respectively provided on the two opposite outer walls of the inner ring body 201. The outer diameter of the abutment blades 203 increases in the same direction. A handle 4 for rotating the cam ring 2 is also connected to the inner wall of the cam ring 2. The handle 4 is arc-shaped, and a groove matching the handle 4 is provided on the inner wall of the inner ring body 201. Both ends of the handle 4 are respectively engaged in the groove. When the cam ring 2 rotates, the abutment blades 203 on its outer circumference can push or release the cam actuator 5 as the outer diameter changes. The handle 4 is connected to the inner wall of the cam ring 2, and the handle 4 is used to drive the cam ring 2 to rotate, making operation more convenient.
[0036] like Figure 9 As shown, the mounting ring 1 has an inner boss 102 on the side of the cam ring 2 opposite to the connecting part 101. The surface of the inner boss 102 has a serrated groove 103, such as... Figure 10 As shown, the surface of the cam ring 2 is also provided with ribs 204 that match the serrated grooves 103. The inner boss 102 is the part that extends from the inner wall of the mounting surface ring 1 towards the center. It serves two purposes: firstly, to bear the weight of the cam ring 2, and secondly, to provide the serrated grooves 103 to prevent the cam ring 2 from loosening. To prevent the cam ring 2 from loosening during use after it has been rotated into place, ribs 204 are also provided between the cam ring 2 and the mounting surface ring 1 to cooperate with the serrated grooves 103 to prevent loosening. The rib 204 is a protrusion on the end face of the cam ring 2, and its end has a certain curvature to facilitate its rotation from one groove to the next. The rib 204 can be engaged in the serrated grooves 103 and will not loosen when the cam ring 2 is not rotated. When the cam ring 2 is rotated, the rib 204 will rotate step by step along each groove in the serrated grooves 103. In addition, when the cam ring 2 is rotated, the rib 204 moves within the serrated groove 103. The collision between the rib 204 and the serrated groove 103 produces a "click-click-click..." sound, which not only serves as an indication of the rotation angle but also enhances the sense of sophistication in the use of the lamp.
[0037] The working principle of this embodiment is as follows: In the initial state, such as... Figure 4As shown, the mounting spring 3 on the mounting ring 1 is inelastic. One end of the cam actuator 5 abuts against the minimum outer diameter of the cam ring 2, and the other end abuts against the inner surface of the expansion piece 32 on the mounting spring 3. When installation is required, the cam ring 2 is rotated in one direction (clockwise in this embodiment) by the handle 4. The outer diameter corresponding to the contact part between the cam ring 2 and the cam actuator 5 gradually increases, thereby gradually pushing the cam actuator 5 outward. The cam actuator 5 then pushes the expansion piece 32 outward, so that the expansion pieces 32 on both sides form an outward V-shape. In this way, it can be easily snapped into the ceiling hole of the ceiling 9 through an inverted V-shape. In other embodiments, the number of mounting springs 3 can be increased, for example, the number of mounting springs 3 can be set to 3 or 4, to increase the force points and make the installation more stable. Figure 11 and Figure 12 As shown, since the outer diameter of the inverted V-shape is within a certain range, the width requirement for the ceiling hole does not need to be very precise, and there is no requirement for the thickness of the ceiling 9. In addition, the use of the rib 204 on the cam ring 2 and the groove of the sawtooth groove 103 can prevent the cam ring 2 and the mounting spring 3 from loosening on their own. When it is necessary to remove the recessed light fixture, simply rotate the cam ring 2 in the opposite direction (counterclockwise in this embodiment) by the handle 4. The holding force of the cam ring 2 on the cam actuator 5 gradually decreases. Under the action of the self-restoring force of the mounting spring 3, the cam actuator 5 retracts, and the expansion piece 32 on the mounting spring 3 retracts, no longer limiting the ceiling hole, so the entire mounting ring 1 and even the light fixture can be removed.
[0038] This embodiment, through the interaction of the cam ring 2, the cam actuator 5, and the mounting spring 3, can adapt to different ceiling thicknesses and has low requirements for the width of the ceiling holes. Installation and disassembly do not require other tools, making the operation more convenient, enabling quick installation and disassembly, stable and reliable installation, and a relatively simple structure with lower manufacturing costs. Furthermore, a limiting design is added at the position of the cam ring 2 and the mounting surface ring 1 to prevent loosening after installation.
[0039] Example 2
[0040] This embodiment is similar to Embodiment 1, except that: in this embodiment, the angle between the expansion piece 32 and the outer wall of the mounting surface ring 1 is in the range of 0 to 30°, that is, the expansion piece 32 can be expanded outward to about 30°; the expansion piece 32 can be tilted to about 30° to achieve the upper limit installation of the ceiling hole.
[0041] Example 3
[0042] This embodiment is similar to Embodiment 1, except that in this embodiment, the end face of the cam actuator 5 is in the shape of an "I" and the actuator hole 8 is an "I" shaped hole that matches the cam actuator 5. In this embodiment, the cam actuator 5 with an "I" shaped cross-section can slide very stably in the "I" shaped actuator hole 8.
[0043] 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 can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
