Abstract
Description
Technical Field
[0001] This application belongs to the field of lighting product design technology, and specifically relates to a lighting fixture. Background Technology
[0002] With the continuous development of lighting fixtures, recessed lighting fixtures are gradually gaining popularity among users. These fixtures can be embedded in ceilings or other mounting bases. A lighting fixture may include a lamp body, a rotating frame, a rotating body, and a face ring, with the lamp body, rotating frame, and rotating body all mounted within the face ring.
[0003] Specifically, the rotating frame drives the lamp body and the rotating body to rotate around the circumference of the face ring, thereby achieving the rotation function of the lamp body. The rotating body is fitted inside the rotating frame and connected to the lamp body. The rotating body drives the lamp body to rotate around the radial line of the face ring, thereby achieving the angle adjustment function of the lamp body. However, this arrangement results in more parts for the lighting fixture and also leads to higher production costs.
[0004] In summary, the lighting fixtures involved in the relevant technologies have the problems of having a large number of parts and high production costs. Utility Model Content
[0005] This application discloses a lighting fixture to solve the problems of numerous parts and high production costs in lighting fixtures involved in related technologies.
[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:
[0007] A lighting fixture includes a face ring, a lamp body, and a connecting frame.
[0008] The face ring is sleeved on the connecting frame, and the face ring and the connecting frame are engaged in an axial upper limit fit of the face ring, and the connecting frame can rotate relative to the face ring around the axis of the face ring;
[0009] The lamp body includes a light-emitting element and a protective shell. The light-emitting element is disposed inside the protective shell. The protective shell is movably connected to the connecting frame and can rotate relative to the connecting frame about the radial line of the face ring.
[0010] The technical solution adopted in this application can achieve the following beneficial effects:
[0011] In this application, because the protective shell of the lamp body is movably connected to the connecting frame, and the face ring and the connecting frame are fitted at the upper limit of the face ring's axial direction, the lamp body can be stably mounted on the face ring via the connecting frame. Furthermore, since the connecting frame can rotate relative to the face ring's axis (i.e., rotate circumferentially around the face ring), the lamp body can achieve a rotation function. Simultaneously, because the protective shell can rotate relative to the connecting frame about the face ring's radial line, the lamp body can achieve an angle adjustment function. Therefore, this application can simultaneously achieve both rotation and angle adjustment functions of the lamp body through the connecting frame. This not only reduces the number of components in the lighting fixture but also lowers production and labor costs. Thus, the lighting fixture disclosed in this application solves the problems of numerous components and high production costs associated with related technologies. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0026] The lighting fixtures disclosed in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0027] Please refer to Figures 1-8 This application discloses a lighting fixture, which includes a face ring 100, a lamp body 200 and a connecting frame 300.
[0028] The face ring 100 is a basic component of the lighting fixture. It can provide a mounting base for other components of the lighting fixture, such as the lamp body 200 and the connecting frame 300. That is, the lamp body 200 and the connecting frame 300 can be mounted on the face ring 100. At the same time, the face ring 100 can serve as the outer structure of the lighting fixture to play a certain decorative role.
[0029] Specifically, the face ring 100 is sleeved on the outside of the connecting frame 300. The face ring 100 and the connecting frame 300 are engaged in the upper limit of the face ring 100 in the axial direction, so that when the operator installs the connecting frame 300 on the face ring 100, the connecting frame 300 is not easy to fall off the face ring 100 due to its own weight. In addition, the connecting frame 300 can rotate relative to the face ring 100 around the axis of the face ring 100, that is, the connecting frame 300 can rotate in the face ring 100.
[0030] The lamp body 200, as a main component of the lighting fixture, is used to realize the lighting function of the lighting fixture. Specifically, the lamp body 200 may include a light-emitting element and a protective shell 240. The light-emitting element is disposed within the protective shell 240. Optionally, the protective shell 240 can be integrally molded, that is, the protective shell 240 can be a one-piece structure, specifically it can be integrally molded by die casting, injection molding, or other methods. The light-emitting element realizes the lighting function of the lighting fixture, and the protective shell 240 can protect the light-emitting element. The protective shell 240 can be a ring-shaped protective shell to give the protective shell 240 a light-focusing effect.
[0031] The protective shell 240 is movably connected to the connecting frame 300, that is, the protective shell 240 can be installed on the face ring 100 through the connecting frame 300, so that the entire lamp body 200 can be installed on the face ring 100 through the connecting frame 300. Since the connecting frame 300 can rotate relative to the face ring 100 around the axis of the face ring 100, this allows the lamp body 200 to rotate relative to the face ring 100 around the axis of the face ring 100.
[0032] Furthermore, the protective shell 240 can rotate relative to the connecting frame 300 about the radial line of the face ring 100, which allows the lamp body 200 to rotate relative to the connecting frame 300 about the radial line of the face ring 100. In other words, the lamp body 200 can swing relative to the connecting frame 300 and the face ring 100, thereby changing the illumination direction of the light-emitting element of the lamp body 200. This arrangement can achieve the effect of adjusting the illumination angle of the lamp body 200. At the same time, by rotating the lamp body 200 and the connecting frame 300 relative to the face ring 100 about the axis of the face ring 100, the lighting fixture can achieve a wider illumination range.
[0033] Furthermore, since the lamp body 200 can be directly connected to the connecting frame 300 through the protective shell 240, there are basically no other components around the lamp body 200. This facilitates heat dissipation of the lamp body 200. In other words, this arrangement has a good heat dissipation effect on the lamp body 200, thereby ensuring that the light-emitting component can always work normally.
[0034] In this application, since the protective shell 240 of the lamp body 200 is movably connected to the connecting frame 300, and the face ring 100 and the connecting frame 300 are engaged in the axial upper limit fit of the face ring 100, the lamp body 200 can be stably mounted on the face ring 100 through the connecting frame 300. Furthermore, since the connecting frame 300 can rotate relative to the face ring 100 around its axis, i.e., it can rotate circumferentially along the face ring 100, the lamp body 200 can achieve a rotation function through the connecting frame 300. Simultaneously, since the protective shell 240 can rotate relative to the connecting frame 300 around the radial line of the face ring 100, the lamp body 200 can achieve an angle adjustment function. Therefore, this application can simultaneously achieve the rotation and angle adjustment functions of the lamp body 200 through the connecting frame 300. This not only reduces the number of parts in the lighting fixture but also lowers the production and labor costs of the lighting fixture. Therefore, the lighting fixture disclosed in this application can solve the problems of numerous parts and high production costs in lighting fixtures related to the relevant technology.
[0035] Optionally, to facilitate the movable connection between the protective shell 240 and the connecting frame 300, i.e. to facilitate the adjustment of the illumination angle of the lamp body 200, one of the protective shell 240 and the connecting frame 300 may be provided with an arc-shaped protrusion, and the other of the protective shell 240 and the connecting frame 300 may be provided with an arc-shaped groove. The arc-shaped protrusion and the arc-shaped groove are slidably engaged, so that the protective shell 240 and the connecting frame 300 are movablely connected through the arc-shaped protrusion and the arc-shaped groove.
[0036] In another embodiment, the lighting fixture may also include a pivot, please refer to [reference needed]. Figure 1 , Figure 4 , Figure 6 and Figure 7 The protective shell 240 may be provided with a first through hole 210, and the connecting frame 300 may be provided with a second through hole 310. The rotating shaft is movably disposed in the first through hole 210 and the second through hole 310, that is, the rotating shaft can rotate, move or perform a combination of rotation and movement relative to the first through hole 210 and the second through hole 310. Furthermore, the protective shell 240 can be connected to the connecting frame 300 through the cooperation of the rotating shaft with the first through hole 210 and the second through hole 310. In other words, the effect of directly connecting the lamp body 200 and the connecting frame 300 can be achieved through the rotating shaft.
[0037] In this embodiment, the extension direction of the rotating shaft is parallel to the radial direction of the face ring 100. This allows the protective shell 240 to rotate radially relative to the connecting frame 300 around the face ring 100 by rotating around the axis of the rotating shaft, thereby achieving the angle adjustment function of the lamp body 200. Simultaneously, since the rotating shaft is movably disposed within the first through hole 210 and the second through hole 310, the assembly and disassembly of the lamp body 200 and the connecting frame 300 are relatively simple and quick. Optionally, the aforementioned rotating shaft can be a cylindrical crossbar or a component such as a rivet; however, this embodiment does not impose specific limitations on this.
[0038] Alternatively, please refer to Figure 1 , Figure 4 , Figure 6 and Figure 7 One of the protective shell 240 and the connecting frame 300 has a protruding guide protrusion 320, and the other of the protective shell 240 and the connecting frame 300 has a guide groove 220. The guide protrusion 320 surrounds one of the first through hole 210 and the second through hole 310, and the guide groove 220 is connected to the other of the first through hole 210 and the second through hole 310.
[0039] During the assembly of the lamp body 200 and the connecting frame 300, the guide protrusion 320 can engage with the guide groove 220 to facilitate the alignment and communication between the first through hole 210 and the second through hole 310. Simultaneously, the engagement between the guide protrusion 320 and the guide groove 220 provides a certain limiting function, making it easier for the operator to smoothly place the aforementioned rotating shaft within the first through hole 210 and the second through hole 310, thereby facilitating the assembly of the lamp body 200 and the connecting frame 300. Of course, in other embodiments, the guide protrusion 320 may not be present on one of the protective shell 240 and the connecting frame 300, and the guide groove 220 may not be present on the other.
[0040] Alternatively, please refer to Figures 3 to 6 To prevent the lamp body 200 and the connecting frame 300 from falling off the face ring 100, and to ensure the stability of the limiting fit between the connecting frame 300 and the face ring 100, an annular protrusion 110 is provided on the inner surface of the face ring 100 facing the connecting frame 300. The connecting frame 300 is provided with a first limiting part 330 and a stop part 340 spaced apart. In the axial direction of the face ring 100, the annular protrusion 110 has a first annular surface 111 and a second annular surface 112 arranged opposite to each other. The first limiting part 330 and the first annular surface 111 are in a limiting fit in the illumination direction of the lighting fixture, that is, the first limiting part 330 and the first annular surface 111 are in a limiting fit in the direction of gravity. This can ensure the stability of the lamp body 200 and the connecting frame 300 in the face ring 100.
[0041] In this embodiment, the stop portion 340 can engage with the second annular surface 112 in a direction opposite to the illumination direction of the lighting fixture. That is, during the assembly of the connecting frame 300 and the face ring 100, the stop portion 340 ensures that the connecting frame 300 is properly installed within the face ring 100. Simultaneously, since the stop portion 340 and the first limiting portion 330 engage with the same annular protrusion 110, and the limiting engagement direction of the annular protrusion 110 and the stop portion 340 is completely opposite to that of the annular protrusion 110 and the first limiting portion 330, this simplifies the structural complexity of the face ring 100. Furthermore, under the combined limiting effect of the stop portion 340 and the first limiting portion 330, the lamp body 200 and the connecting frame 300 can be more stably installed within the face ring 100. Of course, in other embodiments, the connecting frame 300 may not have the stop portion 340.
[0042] Optionally, the connecting frame 300 has a first side near the lamp body 200. This first side may have a first clearance notch 350, which can avoid interference between the connecting frame 300 and the protective shell 240 during the rotation of the lamp body 200 relative to the connecting frame 300. This prevents the range of rotation of the lamp body 200 from becoming smaller, thereby preventing the adjustment range of the lamp body 200 from becoming smaller, and consequently preventing the illumination range of the lighting fixture from becoming smaller. Of course, in other embodiments, the first side may not have the first clearance notch 350.
[0043] Optionally, the number of first limiting parts 330 can be one.
[0044] In another embodiment, the number of first limiting portions 330 can be at least two, including a first sub-limiting portion 331 and a second sub-limiting portion 332 arranged circumferentially along the connecting frame 300. Both the first sub-limiting portions 331 and 332 can be located at the first clearance notch 350, and both can be elastic limiting buckles. In this case, during the assembly or disassembly of the face ring 100 and the connecting frame 300, the first sub-limiting portions 331 and 332 are easily deformed, thereby facilitating the assembly or disassembly of the face ring 100 and the connecting frame 300. Furthermore, in this embodiment, multiple first limiting portions 330 can further ensure the installation stability of the lamp body 200 and the connecting frame 300 within the face ring 100.
[0045] Optionally, as can be seen from the above, the structure of the first sub-limiting part 331 and the structure of the second sub-limiting part 332 can be the same, that is, both the first sub-limiting part 331 and the second sub-limiting part 332 can be elastic limiting buckles.
[0046] In another embodiment, a second sub-limiting portion 332 is provided on the outer surface of the connecting frame 300. The second sub-limiting portion 332 can be an arc-shaped limiting protrusion, that is, the outer surface of the second sub-limiting portion 332 is an arc surface. This makes the contact area between the second sub-limiting portion 332 and the annular protrusion 110 smaller, and thus the sliding friction force generated between the two is smaller. This makes it easier for the connecting frame 300 to drive the lamp body 200 to rotate relative to the face ring 100 around the axis of the face ring 100.
[0047] Simultaneously, during the specific assembly of the connecting frame 300 and the face ring 100, the first sub-limiting part 331 and the second sub-limiting part 332 first contact the second annular surface 112. Since the first sub-limiting part 331 is an elastic limiting buckle, under the squeezing action of the annular protrusion 110, the first sub-limiting part 331 will deform, thereby passing over the annular protrusion 110 and reaching the top of the first annular surface 111 and contacting it. Since the second sub-limiting part 332 is an arc-shaped limiting protrusion, the arc surface of the second sub-limiting part 332 is more likely to slide relative to the annular protrusion 110, thereby making it easier for the second sub-limiting part 332 to pass over the annular protrusion 110 and reach the top of the first annular surface 111 and contact it. At the same time, the stop part 340 contacts the second annular surface 112, thereby completing the operation of assembling the connecting frame 300 and the face ring 100.
[0048] Optionally, the number of first sub-limiting parts 331 can be at least two, and each first sub-limiting part 331 can be spaced apart at the first clearance notch 350 so that the connecting frame 300 is balanced in force within the face ring 100.
[0049] Alternatively, please refer to Figure 1 and Figure 6 The connecting frame 300 may also be provided with a stress-relieving hole 360, which can be a strip-shaped hole. The second sub-limiting part 332, i.e., the arc-shaped limiting protrusion, is located near the stress-relieving hole 360. During the specific assembly of the connecting frame 300 and the face ring 100, since the annular protrusion 110 can squeeze the arc-shaped limiting protrusion, and under the action of the stress-relieving hole 360, the arc-shaped limiting protrusion can deform inward into the connecting frame 300 to generate a larger clearance space, thereby avoiding the annular protrusion 110. This ensures that the arc-shaped limiting protrusion can more easily pass over the annular protrusion 110 and cooperate with the first annular surface 111 for limiting. Of course, in other embodiments, the connecting frame 300 may not be provided with a stress-relieving hole 360.
[0050] Optionally, the unloading hole 360 can be a straight unloading hole.
[0051] In another embodiment, the stress relief hole 360 can be a V-shaped structure or a U-shaped structure, and the stress relief hole 360 surrounds the arc-shaped limiting protrusion. When the arc-shaped limiting protrusion is subjected to the force applied by the annular protrusion 110, the arc-shaped limiting protrusion and its surrounding structure are more likely to deform under the action of the stress relief hole 360, thereby making room for a larger space so that the arc-shaped limiting protrusion can pass over the annular protrusion 110.
[0052] Optionally, the number of stop portions 340 can be one.
[0053] In another embodiment, the number of stop portions 340 can be at least two. Multiple stop portions 340 have a more obvious stopping effect on the connecting frame 300, that is, the stopping stability is higher.
[0054] Optionally, each of the first limiting parts 330 can be arranged in a concentrated manner, and each of the stop parts 340 can be arranged in a concentrated manner, that is, in the circumferential direction of the connecting frame 300, each of the first limiting parts 330 and each of the stop parts 340 can be distributed on different sides of the connecting frame 300.
[0055] In another embodiment, the first limiting part 330 and the stop part 340 can be arranged alternately in the circumferential direction of the connecting frame 300 so that the force on the connecting frame 300 at various points in the face ring 100 is more balanced.
[0056] Alternatively, please refer to Figure 1 and Figure 8 The lighting fixture may also include a decorative ring 400, which is fitted onto the lamp body 200, specifically onto the protective shell 240. The decorative ring 400 has a decorative effect, which can improve the appearance of the lighting fixture. Of course, in other embodiments, the lighting fixture may not include the decorative ring 400.
[0057] Optionally, the decorative ring 400 may be provided with a second clearance notch 410, which can avoid interference between the decorative ring 400 and the protective shell 240 during the rotation of the lamp body 200 relative to the connecting frame 300. This prevents the range of rotation of the lamp body 200 from becoming smaller, thereby preventing the adjustment range of the lamp body 200 from becoming smaller, and consequently preventing the illumination range of the lighting fixture from becoming smaller. Of course, in other embodiments, the decorative ring 400 may not have the second clearance notch 410.
[0058] Optionally, the decorative ring 400 can be mounted on the face ring 100, and the two can be bonded together.
[0059] In another embodiment, one of the face ring 100 and the decorative ring 400 may be provided with a second limiting part 420, and the other of the face ring 100 and the decorative ring 400 may be provided with an annular groove 120. The second limiting part 420 and the annular groove 120 are engaged in an axial limiting fit of the face ring 100, that is, the decorative ring 400 and the face ring 100 are connected through the second limiting part 420 and the annular groove 120. This connection method can facilitate the disassembly, maintenance or replacement of the decorative ring 400 and the face ring 100.
[0060] Alternatively, please refer to Figure 8To further facilitate the assembly or disassembly of the decorative ring 400 and the face ring 100, a third through hole 421 may be provided on the second limiting part 420. This makes it easier for the second limiting part 420 to deform under force, thereby making it easier to engage or disengage with the annular groove 120. Of course, in other embodiments, the second limiting part 420 may not have a third through hole 421. In this case, the second limiting part 420 may be an elastic limiting buckle to facilitate the assembly or disassembly of the decorative ring 400 and the face ring 100.
[0061] Optionally, the number of second limiting parts 420 can be one.
[0062] In another embodiment, the number of second limiting portions 420 can be at least two, and multiple second limiting portions 420 can be limited and cooperated with the same annular groove 120, which can further improve the assembly stability of the decorative ring 400 and the face ring 100.
[0063] Alternatively, please refer to Figure 2 The lighting fixture may also include a heat sink 500, which is detachably disposed on the side of the lamp body 200 away from the connecting frame 300. The heat sink 500 can further reduce the temperature of the lamp body 200 to ensure stable operation of the lighting fixture. Simultaneously, a portion of the heat sink 500 can be located within the second clearance notch 410 to reduce the overall space occupied by the lighting fixture. Of course, in other embodiments, the lighting fixture may not include the heat sink 500.
[0064] In this embodiment, the heat sink 500 can be a heat sink, and the number of heat sinks can be at least two. Multiple heat sinks can be installed sequentially on the lamp body 200. In actual use, the operator can selectively install different numbers of heat sinks according to the power of the light-emitting component, so as to ensure the heat dissipation effect of the lamp body 200 while minimizing production costs.
[0065] Optionally, one of the decorative ring 400 and the protective shell 240 is provided with a limiting rib 430 protruding from it, and the other of the decorative ring 400 and the protective shell 240 is provided with a limiting groove 230. The limiting rib 430 and the limiting groove 230 are engaged in a limiting fit in the circumferential direction of the decorative ring 400, so that the decorative ring 400 can rotate relative to the face ring 100. Specifically, during the rotation of the lamp body 200 around the axis of the face ring 100, under the limiting action of the limiting rib 430 and the limiting groove 230, the decorative ring 400 can rotate with the lamp body 200. That is, the decorative ring 400, the lamp body 200 and the heat sink 500 can rotate together. This can avoid interference between the decorative ring 400 and the heat sink 500 due to the rotation of the heat sink 500 and the lamp body 200 relative to the decorative ring 400. In other words, this arrangement allows the lamp body 200 to have a larger rotation angle. Of course, in other embodiments, one of the decorative ring 400 and the protective shell 240 may not have a protruding limiting rib 430, and the other of the decorative ring 400 and the protective shell 240 may not have a limiting groove 230.
[0066] Alternatively, please refer to Figure 2 The lighting fixture may also include a support member 600, which is typically an elastic support member. The support member 600 is mounted on the outer peripheral surface of the face ring 100 so that after the lighting fixture is embedded in the ceiling or other mounting base, the support member 600 can support other components of the lighting fixture so that the entire lighting fixture can be stably installed on the ceiling or other mounting base.

As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment.

[0068] The above description is merely an embodiment of this application and is not intended to limit this application.
