Description

Technical Field

[0001] This disclosure relates to the technical field of downlights, and in particular to a detachable lampshade and a downlight. Background Technology

[0002] Downlights are commonly used for lighting in corridors, stairwells, and small indoor spaces, favored for their compact design and soft light distribution. However, after a period of use, the lampshades of downlights inevitably accumulate dust, grease, and other impurities. This not only reduces the brightness and clarity of the light but can also affect the overall lighting effect and aesthetics of the room. Therefore, to ensure that downlights continue to provide a good lighting environment, the lampshades need to be removed and cleaned regularly to maintain optimal lighting performance.

[0003] Existing technologies, such as the LED surface-mounted downlight proposed in patent CN111486381B, include a lampshade, a light source board, a lamp body, a sheathed wire, and a mounting bracket. The lampshade, light source board, sheathed wire, and mounting bracket are all detachably mounted on the lamp body, and the sheathed wire is electrically connected to the light source board. In this downlight, the lampshade, light source board, sheathed wire, and mounting bracket are all connected to the lamp body using a detachable snap-fit ​​structure, eliminating the need for screws. This makes assembly very convenient and simple, improving assembly efficiency and reducing costs. When disassembly of the downlight is required, simply open the snaps; disassembly is convenient and simple, and does not damage the downlight's structure.

[0004] However, when disassembling the lampshade of the aforementioned downlight, the lamp body must first be removed from the mounting bracket before the lampshade can be removed from the lamp body, which greatly increases the difficulty of disassembling the lampshade and makes the aforementioned downlight less convenient to use. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a detachable lampshade and downlight with better ease of use.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A detachable lampshade is used to install on the light outlet of a downlight body, the detachable lampshade including a reflector and a pushing component;

[0008] The outer periphery of the reflector has an elastic snap-fit ​​flange. A clearance area is formed between the snap-fit ​​end of the elastic snap-fit ​​flange and the outer peripheral wall of the reflector. The snap-fit ​​end of the elastic snap-fit ​​flange is used to snap and fix the reflector into the snap-fit ​​groove of the lamp body, so that the reflector is snap-fitted and fixed onto the lamp body. The pushing assembly includes a pushing member and a pressing member. The pushing member is disposed within the snap-fit ​​groove, and is positioned opposite to the snap-fit ​​end of the elastic snap-fit ​​flange.

The snap-fit ​​portion is used to snap-fit ​​and fix the reflector in the snap-fit ​​groove.

[0011] In one embodiment, the pusher includes a pushing portion and an abutting portion. The pushing end of the pusher is disposed on the pushing portion, and the pressing abutting end of the pusher is disposed on the abutting portion. A limiting groove is formed on one side of the abutting portion facing the elastic member. One end of the elastic member is disposed in the limiting groove. The pushing portion and the abutting portion are fixedly connected. The connection between the pushing portion and the abutting portion is used for rotatable connection to the inner wall of the snap-fit ​​groove.

[0012] In one embodiment, the length of the pushing part is greater than the length of the abutting part.

[0013] In one embodiment, a first guide slope is formed at the top of the snap-fit ​​portion.

[0014] A downlight includes a lamp body and a detachable lampshade as described in any of the above embodiments. The snap-fit ​​end of the elastic snap-fit ​​flange is snap-fitted and fixed in the snap-fit ​​groove of the lamp body, so that the lampshade is snap-fitted and fixed on the lamp body. A pusher is disposed in the snap-fit ​​groove, and the pusher end of the pusher pushes the snap-fit ​​end of the elastic snap-fit ​​flange out of the snap-fit ​​groove. One end of the pressing member is disposed at the top of the lamp body, and the connecting end between the pusher end and the pressing abutment end of the pusher is rotatably connected to the inner wall of the snap-fit ​​groove.

[0015] In one embodiment, the lamp body further has a guide flange, the snap-fit ​​groove is formed on the lamp body and extends to a side of the guide flange away from the lamp body, and a second guide slope is formed at the bottom of the snap-fit ​​end of the elastic snap-fit ​​flange, the second guide slope being disposed opposite to the guide flange.

[0016] In one embodiment, the lamp body includes two limiting plates, which are respectively fixed to both sides of the guide flange to form a guide limiting groove.

[0017] In one embodiment, a third guide slope is formed at the top of the guide flange, and the third guide slope is disposed opposite to the second guide slope.

[0018] In one embodiment, the lamp body also has a guide limiting hole that communicates with the snap-fit ​​groove. The guide limiting hole extends to the top of the lamp body. One end of the pressing member passes through the guide limiting hole and protrudes from the top of the lamp body. The pressing member is limited within the guide limiting hole.

[0019] In one embodiment, the outer peripheral wall of the lamp body is formed with a snap fastener, which is used to snap and fix it in a snap fastener groove inside the building body.

[0020] In one embodiment, the downlight further includes a light-emitting element, the lamp body has a mounting groove communicating with the light outlet, the light-emitting element is installed and fixed in the mounting groove, and the light-emitting end of the light-emitting element is arranged facing the light outlet.

[0021] In one embodiment, the outer peripheral wall at the top of the lamp body is formed with an annular abutment flange for abutting against the main building body.

[0022] In one embodiment, the inner wall of the snap-fit ​​groove is further provided with a connecting flange, and a limiting hole is formed between the pushing end of the pusher and the pressing end of the pusher. The connecting flange passes through the limiting hole, and the pusher is rotatably connected to the connecting flange.

[0023] Compared with the prior art, this disclosure includes, but is not limited to, the following advantages:

[0024] 1. The aforementioned detachable lampshade features an elastic snap-fit ​​flange on its outer periphery. A clearance area is formed between the snap-fit ​​end of the elastic snap-fit ​​flange and the outer peripheral wall of the lampshade. The snap-fit ​​end of the elastic snap-fit ​​flange is used to snap and fix the lampshade into the snap-fit ​​groove of the lamp body, allowing the lampshade to be securely fixed to the lamp body. Users only need to install the lampshade in the preset position on the lamp body, and the snap-fit ​​end of the elastic snap-fit ​​flange will extend into the snap-fit ​​groove through its own elastic deformation, thus ensuring the lampshade is firmly fixed to the lamp body. This not only greatly reduces the installation difficulty of the lampshade and improves the ease of use of the downlight, but also prevents the lampshade from detaching from the lamp body due to collisions or other external factors during use, significantly improving the stability of the downlight.

[0025] 2. The pushing assembly includes a pushing member and a pressing member. The pushing member is positioned within the snap-fit ​​groove and is opposite to the snap-fit ​​end of the elastic snap-fit ​​flange. The pushing end of the pushing member is used to push the snap-fit ​​end of the elastic snap-fit ​​flange out of the snap-fit ​​groove. One end of the pressing member is positioned at the top of the lamp body, and the other end of the pressing member is positioned within the snap-fit ​​groove and abuts against the pressing end of the pushing member. The connecting end between the pushing end and the pressing end of the pushing member is used for rotatable connection with the inner wall of the snap-fit ​​groove, so that when the user needs to remove the reflector cover, they only need to press the end of the pressing member located at the top of the lamp body by hand. The other end can apply pressure to the pressing and abutting end of the pusher, causing the pressing and abutting end of the pusher to rotate relative to the lamp body. At the same time, the pressing and abutting end of the pusher can drive the pushing end of the pusher to rotate relative to the lamp body through the lever action. This allows the pushing end of the pusher to push the snapping end of the elastic snapping flange to move closer to the reflector, so that the snapping end of the elastic snapping flange can disengage from the snapping groove. This allows the user to easily remove the reflector from the lamp body, greatly reducing the difficulty of removing the reflector and further improving the ease of use of the downlight.

[0039] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0040] like Figures 1 to 9 As shown, in one embodiment, a detachable lampshade 100 is installed at the light outlet 210 of the lamp body 200 of the downlight 10. The detachable lampshade 100 includes a reflector 110 and a pushing assembly 120. An elastic snap-fit ​​flange 111 is formed on the outer periphery of the reflector 110. A clearance area 112 is formed between the snap-fit ​​end of the elastic snap-fit ​​flange 111 and the outer peripheral wall of the reflector 110. The snap-fit ​​end of the elastic snap-fit ​​flange 111 is used to snap and fix it in the snap-fit ​​groove 220 of the lamp body 200, so that the reflector 110 is snapped and fixed on the lamp body 200, allowing the user to easily attach the reflector 110 to the lamp body 200. The reflector 110 needs to be installed at the preset position on the lamp body 200. The snap-fit ​​end of the elastic snap-fit ​​flange 111 can then extend into the snap-fit ​​groove 220 through its own elastic deformation, thereby making the reflector 110 securely fixed on the lamp body 200. This not only greatly reduces the installation difficulty of the reflector 110 and improves the ease of use of the downlight 10, but also avoids the phenomenon that the reflector 110 will detach from the lamp body 200 due to collisions or other external factors during the use of the downlight 10, thus greatly improving the stability of the downlight 10.

[0041] like Figures 1 to 9As shown, the pushing assembly 120 further includes a pushing member 121 and a pressing member 122. The pushing member 121 is disposed within the snap-fit ​​groove 220 and is disposed opposite to the snap-fit ​​end of the elastic snap-fit ​​flange 111. The pushing end of the pushing member 121 is used to push the snap-fit ​​end of the elastic snap-fit ​​flange 111 out of the snap-fit ​​groove 220. One end of the pressing member 122 is disposed at the top of the lamp body 200, and the other end of the pressing member 122 is disposed within the snap-fit ​​groove 220 and abuts against the pressing end of the pushing member 121. The connecting end between the pushing end and the pressing end of the pushing member 121 is used to rotatably connect with the inner wall of the snap-fit ​​groove 220, so that when the user needs to remove the reflector cover 110, he only needs to press the pressing member 122 on the lamp body 200 by hand. At one end of the top of the lamp, the other end of the pressing member 122 can apply pressure to the pressing and abutting end of the pushing member 121, so that the pressing and abutting end of the pushing member 121 can rotate relative to the lamp body 200. At the same time, the pressing and abutting end of the pushing member 121 can drive the pushing end of the pushing member 121 to rotate relative to the lamp body 200 through the lever action. This allows the pushing end of the pushing member 121 to push the snap-fit ​​end of the elastic snap-fit ​​flange 111 to move closer to the reflector cover 110, so that the snap-fit ​​end of the elastic snap-fit ​​flange 111 can be disengaged from the snap-fit ​​groove 220. This allows the user to easily remove the reflector cover 110 from the lamp body 200, greatly reducing the difficulty of removing the reflector cover 110 and further improving the ease of use of the downlight 10.

[0042] In this embodiment, when it is necessary to install the reflector 110 on the lamp body 200, the reflector 110 only needs to be installed at the preset position of the lamp body 200. The reflector 110 can be snapped and fixed in the snap groove 220 of the lamp body 200 by the elastic deformation of the snap end of the elastic snap flange 111. This makes the reflector 110 securely fixed on the lamp body 200, greatly reducing the installation difficulty of the reflector 110.

[0043] When it is necessary to remove the reflector 110 from the lamp body 200, simply press one end of the pressing member 122 located at the top of the lamp body 200. The other end of the pressing member 122 will then apply pressure to the pressing end of the pushing member 121, causing the pressing end of the pushing member 121 to rotate relative to the lamp body 200. At the same time, the pressing end of the pushing member 121 will drive the pushing end of the pushing member 121 to rotate relative to the lamp body 200 through leverage. This will allow the pushing end of the pushing member 121 to push the locking end of the elastic locking flange 111 towards the reflector 110, thereby allowing the locking end of the elastic locking flange 111 to disengage from the locking groove 220. This allows the user to easily remove the reflector 110 from the lamp body 200, greatly reducing the difficulty of removing the reflector 110.

[0044] The aforementioned detachable lampshade 100 features an elastic snap-fit ​​flange 111 formed on its outer periphery. A clearance area 112 is formed between the snap-fit ​​end of the elastic snap-fit ​​flange 111 and the outer peripheral wall of the reflector 110. The snap-fit ​​end of the elastic snap-fit ​​flange 111 is used to snap and fix the reflector 110 into the snap-fit ​​groove 220 of the lamp body 200, thus allowing the reflector 110 to be snapped and fixed onto the lamp body 200. This enables the user to simply install the reflector 110 into a preset position on the lamp body 200. The snap-fit ​​end of the snap-fit ​​flange 111 can extend into the snap-fit ​​groove 220 through its own elastic deformation, thereby making the reflector 110 securely fixed to the lamp body 200. This not only greatly reduces the installation difficulty of the reflector 110 and improves the ease of use of the downlight 10, but also avoids the phenomenon that the reflector 110 will detach from the lamp body 200 due to collisions or other external factors during the use of the downlight 10, thus greatly improving the stability of the downlight 10.

[0045] Furthermore, since the pushing assembly 120 includes a pushing member 121 and a pressing member 122, the pushing member 121 is disposed within the snap-fit ​​groove 220, and the pushing member 121 is disposed opposite to the snap-fit ​​end of the elastic snap-fit ​​flange 111. The pushing end of the pushing member 121 is used to push the snap-fit ​​end of the elastic snap-fit ​​flange 111 out of the snap-fit ​​groove 220. One end of the pressing member 122 is disposed at the top of the lamp body 200, and the other end of the pressing member 122 is disposed within the snap-fit ​​groove 220 and abuts against the pressing end of the pushing member 121. The connecting end between the pushing end and the pressing end of the pushing member 121 is used to rotatably connect with the inner wall of the snap-fit ​​groove 220, so that when the user needs to remove the reflector cover 110, he only needs to press the pressing member 122 located at the top of the lamp body 200 by hand. One end of the pressing member 122 can apply pressure to the pressing and abutting end of the pushing member 121, so that the pressing and abutting end of the pushing member 121 can rotate relative to the lamp body 200. At the same time, the pressing and abutting end of the pushing member 121 can drive the pushing end of the pushing member 121 to rotate relative to the lamp body 200 through the lever action. This allows the pushing end of the pushing member 121 to push the snapping end of the elastic snapping flange 111 to move closer to the reflector cover 110, so that the snapping end of the elastic snapping flange 111 can be disengaged from the snapping groove 220. This allows the user to easily remove the reflector cover 110 from the lamp body 200, greatly reducing the difficulty of removing the reflector cover 110 and further improving the ease of use of the downlight 10.

[0046] like Figure 3 As shown, in this embodiment, the elastic snap-fit ​​flange 111 and the reflector 110 are integrally formed to improve the structural compactness of the reflector 110.

[0047] like Figure 3As shown, in one embodiment, the pusher 121 further includes an elastic member 1211, which is disposed in the snap-fit ​​groove 220. One end of the elastic member 1211 is connected to the side of the pusher 121 that is away from the presser 122, and the other end of the elastic member 1211 is connected to the inner wall of the snap-fit ​​groove 220. The elastic member 1211 is used to elastically support the presser end of the pusher 121 so that when the user stops applying pressure to the presser 122, the elastic member 1211 can push the presser end of the pusher 121 to the initial position through its own elastic deformation. At the same time, the presser end of the pusher 121 can drive the pusher end of the pusher 121 to return to the initial position through the lever action, so as to avoid the pusher end of the pusher 121 from obstructing the snap-fit ​​end of the elastic snap-fit ​​flange 111 from extending into the snap-fit ​​groove 220 when the reflector cover 110 is installed, thereby greatly improving the stability of the downlight 10.

[0048] As shown in Figure 3, in this embodiment, the elastic element 1211 is a spring or elastic soft rubber so that when the user stops applying pressure to the pressing element 122, the elastic element 1211 can push the pushing end of the pushing element 121 to the initial position.

[0049] For example, 3 to Figure 5 As shown, in one embodiment, the elastic snap-fit ​​flange 111 includes a connecting portion 1111 and a snap-fit ​​portion 1112. The two ends of the connecting portion 1111 are fixedly connected to the outer peripheral wall of the reflector cover 110 and the snap-fit ​​portion 1112, respectively. The snap-fit ​​of the elastic snap-fit ​​flange 111 is located in the snap-fit ​​portion 1112. A clearance area 112 is formed between the outer peripheral wall of the reflector cover 110 and the snap-fit ​​portion 1112. The snap-fit ​​portion 1112 is used to snap-fit ​​and fix within the snap-fit ​​groove 220, so that when pushed... When the pushing end of component 121 pushes the latching part 1112 to move closer to the reflector cover 110, the clearance area 112 can provide sufficient clearance space for the latching part 1112, so that the latching part 1112 can disengage from the latching groove 220 through its own elastic deformation. This allows the user to easily remove the reflector cover 110 from the lamp body 200, thereby greatly reducing the difficulty of removing the reflector cover 110 and making the downlight 10 more convenient to use.

[0050] For example, 3 to Figure 5 As shown, in this embodiment, the connecting part 1111 and the snap-fit ​​part 1112 are integrally formed to improve the structural compactness of the elastic snap-fit ​​flange 111.

[0051] Such as 3 and Figure 6As shown, in one embodiment, the pusher 121 includes a pusher portion 1212 and an abutment portion 1213. The pusher end of the pusher 121 is disposed on the pusher portion 1212, and the pressing abutment end of the pusher 121 is disposed on the abutment portion 1213. A limiting groove 1213a is formed on one side of the abutment portion 1213 facing the elastic member 1211. One end of the elastic member 1211 is disposed in the limiting groove 1213a. The pusher portion 1212 and the abutment portion 1213 are fixedly connected. The connection between the pusher portion 1212 and the abutment portion 1213 is used for rotatable connection with the inner wall of the locking groove 220, so that the elastic member 1211 is limited to a preset position in the locking groove 220, so as to prevent the elastic member 1211 from falling out of the locking groove 220, which greatly improves the stability of the downlight 10.

[0052] Such as 3 and Figure 6 As shown, in one embodiment, the length of the pushing part 1212 is greater than the length of the abutting part 1213, so that the user can press the pressing part 122 with less effort, further reducing the difficulty of disassembling the reflector cover 110, and thus greatly improving the ease of use of the downlight 10.

[0053] For example, 3 to Figure 5 As shown, in one embodiment, the top of the snap-fit ​​portion 1112 is formed with a first guide slope 1112a, so that when the pushing end of the pushing member 121 pushes the snap-fit ​​portion 1112 toward the direction close to the reflector cover 110, the snap-fit ​​portion 1112 can be disengaged from the snap-fit ​​groove 220 along the guiding direction of the first guide slope 1112a, which further reduces the difficulty of disassembling the reflector cover 110 and greatly improves the ease of use of the downlight 10.

[0054] This disclosure also provides a downlight 10, including a lamp body 200 and a detachable lampshade 100 as described in any of the above embodiments. The snap-fit ​​end of the elastic snap-fit ​​flange 111 is snap-fitted and fixed in the snap-fit ​​groove 220 of the lamp body 200 so that the lampshade is snap-fitted and fixed on the lamp body 200. The pusher 121 is disposed in the snap-fit ​​groove 220. The pusher end of the pusher 121 pushes the snap-fit ​​end of the elastic snap-fit ​​flange 111 out of the snap-fit ​​groove 220. One end of the pressing member 122 is disposed at the top of the lamp body 200. The connecting end between the pusher end of the pusher 121 and the pressing abutment end of the pusher 121 is rotatably connected to the inner wall of the snap-fit ​​groove 220.

[0055] For example, 3 to Figure 8As shown, in one embodiment, the lamp body 200 further includes a guide flange 230, a snap-fit ​​groove 220 formed on the lamp body 200 and extending to the side of the guide flange 230 facing away from the lamp body 200, and a second guide slope 1113 formed at the bottom of the snap-fit ​​end of the elastic snap-fit ​​flange 111. The second guide slope 1113 is disposed opposite to the guide flange 230 so that during the process of installing the reflector cover 110 to the preset position of the lamp body 200, the snap-fit ​​end of the elastic snap-fit ​​flange 111 can pass through the second guide slope 1113. Guided by its own elastic deformation, the reflector moves towards the reflector 110, allowing the reflector 110 to be installed in a preset position. When the reflector 110 is installed in the preset position, the snap-fit ​​end of the elastic snap-fit ​​flange 111 can extend into and snap into the snap-fit ​​groove 220 through its own elastic deformation, so that the reflector 110 can be securely snapped and fixed to the lamp body 200 by the elastic snap-fit ​​flange 111, thereby greatly reducing the installation difficulty of the reflector 110 and further improving the ease of use of the downlight 10.

[0056] For example, 3 to Figure 8 As shown, in one embodiment, the lamp body 200 includes two limiting plates 240. The two guiding limiting plates 240 are respectively fixed to both sides of the guiding flange 230 to form a guiding limiting groove 250. This allows the reflector 110 to be guided by the guiding limiting groove 250 and engaged by the elastic snap-fit ​​flange 111 into the limiting groove 1213a, so that the reflector 110 can be securely installed and fixed on the lamp body 200. This avoids misalignment of the reflector 110 and greatly reduces the installation difficulty of the reflector 110.

[0057] For example, 3 to Figure 8 As shown, in one embodiment, a third guide slope 231 is formed at the top of the guide flange 230. The third guide slope 231 is disposed opposite to the second guide slope 1113, so that the user can install the reflector 110 to the preset position of the lamp body 200 with less effort, further reducing the installation difficulty of the reflector 110.

[0058] As shown in Figure 3, in one embodiment, the lamp body 200 also has a guide limiting hole 260 connected to the snap-fit ​​groove 220. The guide limiting hole 260 extends to the top of the lamp body 200. One end of the pressing member 122 passes through the guide limiting hole 260 and protrudes from the top of the lamp body 200, so that when the user presses the pressing member 122, the pressing member 122 can apply pressure to the pressing abutment end of the pushing member 121 along the guiding direction of the guide limiting hole 260, and at the same time facilitates... The user presses the pressing part 122 to further reduce the difficulty of disassembling the reflector cover 110 and improve the user experience; and the pressing part 122 is limited within the guide limiting hole 260 so that the pressing part 122 can be reliably positioned within the guide limiting hole 260, avoiding the phenomenon that the pressing part 122 will detach from the guide limiting hole 260 due to collision or other external factors after the downlight 10 is installed on the building body, which greatly improves the stability of the downlight 10.

[0059] As shown in Figure 1, in one embodiment, the outer peripheral wall of the lamp body 200 is formed with a fastener 270. The fastener 270 is used to snap and fix the lamp body 200 in the fastener groove inside the building body, so that the lamp body 200 can be securely fixed to the building body through the fastener 270. This prevents the lamp body 200 from falling off the building body due to collisions or other external factors during use, and greatly improves the stability of the downlight 10.

[0060] As in 2 and Figure 7 As shown, in one embodiment, the downlight 10 further includes a light-emitting element 300. The lamp body 200 forms a mounting groove 280 communicating with the light outlet 210. The light-emitting element 300 is installed and fixed in the mounting groove 280. The light-emitting end of the light-emitting element 300 is arranged facing the light outlet 210 so that the light emitted from the light-emitting end of the light-emitting element 300 can be emitted from the light outlet 210 through the reflector 110. The reflector 110 reflects the light emitted by the light-emitting element 300 that fails to illuminate the target area, so that the light can be redirected and illuminate the target area. This not only greatly improves the light utilization rate of the downlight, but also significantly improves the lighting effect on the target area.

[0061] As 1 to Figure 3 As shown, in one embodiment, an annular abutment flange 290 is formed on the outer peripheral wall of the top of the lamp body 200. The annular abutment flange 290 is used to abut against the main body of the building so that when the user presses the pressing member 122, the abutment flange can support the lamp body 200, avoiding the phenomenon that the lamp body 200 will collide with the main body of the building due to excessive pressing force, which would cause damage or even destruction to the lamp body 200, and further improving the stability of the downlight 10 in use.

[0062] like Figure 3 and Figure 6As shown, in one embodiment, the inner wall of the snap-fit ​​groove 220 is further provided with a connecting flange 221. The connecting end between the pushing end of the pushing member 121 and the pressing abutting end of the pushing member 121 forms a limiting hole 1214. The connecting flange 221 passes through the limiting hole 1214, and the pushing member 121 and the connecting flange 221 are rotatably connected so that when pressure is applied to the pressing abutting end of the pushing member 121, the pressing abutting end of the pushing member 121 can rotate relative to the lamp body 200, so that the pressing abutting end of the pushing member 121 can drive the pushing end of the pushing member 121 to rotate relative to the lamp body 200 through the lever action, thereby enabling the pushing end of the pushing member 121 to push the snap-fitting end of the elastic snap-fitting flange 111 out of the snap-fit ​​groove 220, so as to facilitate the disassembly of the reflector cover 110.

[0063] Compared with the prior art, this disclosure has at least the following advantages:

[0064] 1. In the aforementioned downlight 10, an elastic locking flange 111 is formed on the outer periphery of the reflector 110. A clearance area 112 is formed between the locking end of the elastic locking flange 111 and the outer peripheral wall of the reflector 110. The locking end of the elastic locking flange 111 is used to lock and fix it within the locking groove 220 of the lamp body 200, so that the reflector 110 is locked and fixed onto the lamp body 200. This allows the user to simply install the reflector 110 into a preset position on the lamp body 200. The snap-fit ​​end of the flange 111 can extend into the snap-fit ​​groove 220 through its own elastic deformation, thereby making the reflector 110 securely fixed to the lamp body 200. This not only greatly reduces the installation difficulty of the reflector 110 and improves the ease of use of the downlight 10, but also avoids the phenomenon that the reflector 110 will detach from the lamp body 200 due to collisions or other external factors during the use of the downlight 10, thus greatly improving the stability of the downlight 10.

[0065] 2. Since the pushing assembly 120 includes a pushing member 121 and a pressing member 122, the pushing member 121 is disposed within the snap-fit ​​groove 220 and is disposed opposite to the snap-fit ​​end of the elastic snap-fit ​​flange 111. The pushing end of the pushing member 121 is used to push the snap-fit ​​end of the elastic snap-fit ​​flange 111 out of the snap-fit ​​groove 220. One end of the pressing member 122 is disposed at the top of the lamp body 200, and the other end of the pressing member 122 is disposed within the snap-fit ​​groove 220 and abuts against the pressing end of the pushing member 121. The connecting end between the pushing end and the pressing end of the pushing member 121 is used to rotatably connect with the inner wall of the snap-fit ​​groove 220, so that when the user needs to remove the reflector cover 110, he only needs to press the pressing member 122 located at the top of the lamp body 200 by hand. At one end of the pressing member 122, the other end can apply pressure to the pressing and abutting end of the pushing member 121, so that the pressing and abutting end of the pushing member 121 can rotate relative to the lamp body 200. At the same time, the pressing and abutting end of the pushing member 121 can drive the pushing end of the pushing member 121 to rotate relative to the lamp body 200 through the lever action. This allows the pushing end of the pushing member 121 to push the snapping end of the elastic snapping flange 111 to move closer to the reflector cover 110, so that the snapping end of the elastic snapping flange 111 can be disengaged from the snapping groove 220. This allows the user to easily remove the reflector cover 110 from the lamp body 200, greatly reducing the difficulty of removing the reflector cover 110 and further improving the ease of use of the downlight 10.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
