The entire contents of the application are incorporated by reference into this application. Technical Field

[0003] The present application belongs to the technical field of lighting product design, and specifically relates to a lighting fixture. Background Art

[0004] With the continuous development of lighting fixtures, lighting fixtures are gradually developing towards the direction of being lighter and thinner, that is, the thickness of the lighting fixture is smaller. At this time, the internal height space of the lighting fixture is smaller. In order to facilitate the connection of the lampshade and the base of the lighting fixture, they are usually connected through a threaded connector, that is, one end of the threaded connector passes through the base and is connected to the lampshade.

[0005] However, since the threaded connector is usually exposed on the lighting fixture, when the lampshade and the base are connected by the threaded connector, there is a problem of increasing the thickness of the lighting fixture, which is not conducive to the lightweight design of the lighting fixture.

[0006] In summary, the method of connecting lighting fixtures in the related art is not conducive to the lightweight design of lighting fixtures. Summary of the Invention

[0007] The present application discloses a lighting fixture.

[0008] A lighting fixture includes: a base having a first surface; a lampshade having a second surface, the second surface being arranged opposite to the first surface, a first mounting hole being opened on one of the first surface and the second surface and a protruding blocking member; a bending clip being connected to the other of the first surface and the second surface, the first end of the bending clip facing the one of the first surface and the second surface connected to the bending clip, and the second end of the bending clip being laterally limited by the blocking member; a first connecting member being connected to the first mounting hole, and a portion of the first connecting member being located between the first end and the one of the first surface and the second surface connected to the bending clip.

DETAILED DESCRIPTION

[0029] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] The lighting fixture disclosed in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0031] 1 to 19 , the present application discloses a lighting fixture, which includes a base 100, a lampshade 200, a bending buckle 300, and a first connector 400. In one embodiment, the lighting fixture may be a ceiling light or other types of lights.

[0032] The base 100 is a basic component of the lighting fixture, which can provide an installation foundation for other components of the lighting fixture, such as a light source of the lighting fixture and a circuit board that provides working current for the light source. The lampshade 200 is used to be connected to the base 100. The light emitted by the light source can be emitted through the lampshade 200, that is, the lampshade 200 is a light-transmitting lampshade. Of course, the lampshade 200 can also be a light-distributing lampshade. When the base 100 is connected to the lampshade 200, the base 100 has a first surface 110 facing the lampshade 200, and the lampshade 200 has a second surface 210 facing the base 100, that is, the first surface 110 and the second surface 210 are arranged opposite to each other. A first mounting hole 120 and a protruding blocking member 130 can be opened on one of the first surface 110 and the second surface 210. The first mounting hole 120 can be a threaded hole, and the blocking member 130 can protrude toward the other of the first surface 110 and the second surface 210.

[0033] The bending clip 300 is used to connect the base 100 and the lampshade 200. Specifically, the other of the first surface 110 and the second surface 210 is connected to the bending clip 300, that is, the bending clip 300 is provided on the other of the first surface 110 and the second surface 210, and the first end 310 of the two ends of the bending clip 300 is toward the one of the first surface 110 and the second surface 210 connected to the bending clip 300, that is, a part of the bending clip 300 extends toward the one of the first surface 110 and the second surface 210 connected to the bending clip 300, and the second end 320 of the two ends of the bending clip 300 is laterally limited by the blocking member 130, that is, the second end 320 and the blocking member 130 are engaged in a limit position in the direction in which the second end 320 extends toward the blocking member 130, and under the mutual restriction of the second end 320 and the blocking member 130, the base 100 and the lampshade 200 can be prevented from separating in the direction in which the second end 320 extends toward the blocking member 130.

[0034] The first connecting member 400 is connected to the first mounting hole 120. The first connecting member 400 can be a threaded connecting member, that is, at this time, the first connecting member 400 is threadedly matched with the first mounting hole 120. Specifically, a portion of the first connecting member 400 is connected to the first mounting hole 120, that is, a portion of the first connecting member 400 is located in the first mounting hole 120, and another portion of the first connecting member 400 protrudes from the first mounting hole 120 and is located in the space between the first surface 110 and the second surface 210. At the same time, the portion of the first connecting member 400 protruding from the first mounting hole 120 is located between the first end 310 and the first surface 110 and the second surface 210 and is connected to the bent buckle 3 00, that is, the first end 310 and the first connecting member 400 are limited in the thickness direction of the lighting fixture, and under the mutual restriction of the first end 310 and the first connecting member 400, the base 100 and the lampshade 200 can be prevented from separating in the thickness direction, that is, in the thickness direction, the first end 310 and the first connecting member 400 can prevent the base 100 from separating from the lampshade 200, and the direction of the limiting cooperation of the second end 320 and the blocking member 130 is perpendicular to the thickness direction of the lighting fixture, thereby making the base 100 and the lampshade 200 connected through the blocking member 130, the bending buckle 300 and the first connecting member 400, and inseparable.

[0035] In one embodiment, the blocking member 130 may be a blocking plate. In this case, the second end 320 and the blocking member 130 may be positioned perpendicular to the thickness direction and perpendicular to the extending direction of the blocking member 130 .

[0036] In the present application, since the base 100 has a first surface 110 and the lampshade 200 has a second surface 210, the first surface 110 and the second surface 210 are arranged opposite to each other. Therefore, when the base 100 and the lampshade 200 are connected, the first mounting hole 120 and the blocking member 130 are both located in the space between the base 100 and the lampshade 200, that is, the first connecting member 400 connected to the first mounting hole 120 and the bending buckle 300 connected to the first surface 110 or the second surface 210 are both arranged in the space between the base 100 and the lampshade 200. It can be seen that in the present application, the components connecting the base 100 and the lampshade 200 are all located in the space between the base 100 and the lampshade 200, which is conducive to the lightweight design of the lighting fixture.

[0037] Because the first connector 400 is located between the first end 310 of the bending buckle 300 and one of the first and second surfaces 110 and 210 connected to the bending buckle 300, the first end 310 and the first connector 400 are positioned in a limited position in the thickness direction of the lighting fixture, and the second end 320 of the bending buckle 300 is laterally limited by the blocking member 130. That is, the second end 320 and the blocking member 130 are positioned in a limited position in the direction from which the second end 320 extends toward the blocking member 130. This means that the base 100 and the lampshade 200 are inseparablely connected by the bending buckle 300 and the first connector 400, and by the bending buckle 300 and the blocking member 130. Therefore, the lighting fixture disclosed in the present application can solve the problem that the connection method for lighting fixtures in the related art is not conducive to the lightweight and thin design of the lighting fixture.

[0038] In addition, since the components that connect the base 100 and the lampshade 200 are all located in the space between the base 100 and the lampshade 200, that is, the blocking member 130, the bending clip 300 and the first connecting member 400 are all located in the space between the base 100 and the lampshade 200, the blocking member 130, the bending clip 300 and the first connecting member 400 are not exposed, which makes the lighting fixture disclosed in the present application more beautiful, that is, this connection method is not easy to affect the appearance of the lighting fixture.

[0039] In one embodiment, please refer to Figure 2, the lighting fixture may also include a second connecting member 500, the second connecting member 500 may be a threaded connecting member, a mounting column 220 is protruded from the first surface 110 or the second surface 210, the mounting column 220 is provided with a second mounting hole 221, the second mounting hole 221 may be a threaded hole, the bending buckle 300 is provided with a first through hole 330, one end of the second connecting member 500 passes through the first through hole 330 and is connected to the second mounting hole 221, that is, the first through hole 330 and the second mounting hole 221 are arranged opposite to each other, and the second connecting member 500 is threadedly matched with the second mounting hole 221, so that the bending buckle 300 is connected to the base 100 or the lampshade 200 through the second connecting member 500.

[0040] In this embodiment, since the second connector 500 is connected to the second mounting hole 221, that is, the second connector 500 has a larger contact area with the mounting post 220, the second connector 500 has a larger contact area with the base 100 or the lampshade 200, thereby ensuring that the bending buckle 300 can be stably mounted on the base 100 or the lampshade 200. At the same time, the mounting post 220 keeps the bending buckle 300 away from the base 100 or the lampshade 200 on which the mounting post 220 is provided. This allows the bending buckle 300 to be closer to the first connector 400 and the blocking member 130, thereby facilitating positional engagement with the first connector 400 and the blocking member 130. Of course, the bending buckle 300 can also be directly connected to the first surface 110 or the second surface 210 via the second connector 500, that is, no mounting post 220 is provided on the first surface 110 or the second surface 210.

[0041] In one embodiment, please refer to Figures 16, 18 and 19, the first protrusion 222 and the second protrusion 223 are protruded at intervals on the mounting column 220. Specifically, the first protrusion 222 and the second protrusion 223 are protruded at intervals in the area at the top of the mounting column 220 and close to the outer peripheral surface of the mounting column 220, and the two opposite edges of the bending buckle 300 are respectively provided with a first notch 340 and a second notch 350. The first protrusion 222 can pass through the first notch 340 and cooperate with the first notch 340 to limit the position in the first direction and the second direction. The second protrusion 223 can pass through the second notch 350 and cooperate with the second notch 350 to limit the position in the first direction and the third direction. The first direction, the second direction and the third direction are all directions perpendicular to the thickness direction of the lighting fixture, and the second direction is parallel to the third direction and opposite to the third direction.

[0042] Thus, it can be seen that, through the limiting cooperation between the first protrusion 222 and the first notch 340, and the limiting cooperation between the second protrusion 223 and the second notch 350, the first protrusion 222 and the second protrusion 223 can limit the position of the bending buckle 300 in a direction perpendicular to the thickness direction, so that the bending buckle 300 can be stably arranged on the mounting post 220, that is, the bending buckle 300 is positioned and installed on the mounting post 220, so that the bending buckle 300 and the mounting post 220 are connected via the second connecting member 500, that is, the stability of the arrangement of the bending buckle 300 is ensured, and furthermore, the stability of the limiting cooperation between the bending buckle 300, the first connecting member 400, and the blocking member 130 is ensured. Of course, the first protrusion 222 and the second protrusion 223 may also be omitted from the mounting post 220.

[0043] In one embodiment, two protrusions may be provided on the mounting post 220 , namely the first protrusion 222 and the second protrusion 223 described above.

[0044] In another embodiment, please refer to Figure 5, only one protrusion is provided on the mounting column 220, that is, a third protrusion 224 is protruded from the mounting column 220, and the bending buckle 300 is also provided with a second through hole 360, and the second through hole 360 ​​is spaced apart from the first through hole 330, and at least a portion of the third protrusion 224 is located in the second through hole 360, so that the third protrusion 224 and the second through hole 360 ​​are limited in a direction perpendicular to the thickness direction of the lighting fixture, that is, through the limiting cooperation between the third protrusion 224 and the second through hole 360, the bending buckle 300 can be limited in two directions at the same time, that is, in a direction perpendicular to the thickness direction. This can reduce the number of protrusions set on the mounting column 220, thereby reducing the production materials of the protrusions, thereby reducing the production cost of the mounting column 220, and thereby reducing the production cost of the lighting fixture.

[0045] In one embodiment, please refer to Figures 5 and 19, a pre-positioning portion 225 extending along the axial direction of the mounting post 220 is provided on the outer peripheral surface of the mounting post 220, and the pre-positioning portion 225 has a pre-positioning surface 2251. During the process of connecting the base 100 and the lampshade 200, part of the bent clip 300 can be guided and matched with the pre-positioning surface 2251, and the pre-positioning portion 225 can avoid the first end 310, that is, during the process of installing the bent clip 300 on the mounting post 220, part of the bent clip 300 can contact the pre-positioning surface 2251, and the pre-positioning portion 225 can avoid the first end 310. At this time, the pre-positioning surface 2251 can provide a guiding effect, so that the bent clip 300 can be easily matched with the mounting post 220 under the action of the pre-positioning surface 2251, and the first through hole 330 and the second mounting hole 221 can be easily arranged relative to each other, so as to facilitate the connection of the bent clip 300 and the mounting post 220 through the second connecting member 500.

[0046] At the same time, since a portion of the bent buckle 300 can contact the pre-positioning surface 2251, that is, the bent buckle 300 is located close to the mounting post 220, the overall structure of the bent buckle 300 and the mounting post 220 is relatively compact, which can reduce the space occupied by the bent buckle 300 and the mounting post 220. In addition, the pre-positioning portion 225 on the mounting post 220 can reduce the material used to produce the mounting post 220, thereby reducing production costs. Of course, the mounting post 220 can also be provided with the pre-positioning portion 225.

[0047] In one embodiment, please refer to Figures 1 and 7. Since part of the first connecting member 400 protrudes from the first mounting hole 120, the first connecting member 400 has a third surface 410 facing the first mounting hole 120. Specifically, the first connecting member 400 may include a connected connecting portion and a top portion. Part of the connecting portion is connected to the first mounting hole 120. The top portion is an annular top portion, and the top portion protrudes along the circumference of the connecting portion. At this time, the top portion has a third surface 410 facing the first mounting hole 120, so that the first connecting member 400 has a third surface 410 facing the first mounting hole 120. Please refer to Figure 6. The bending buckle 300 may include first elastic limiters that are relatively bent and sequentially connected. The plate 370, the connecting plate 380 and the second elastic limiting plate 390, that is, the bending buckle 300 is an elastic bending buckle, and the first elastic limiting plate 370 can cooperate with the first connecting member 400 to limit the position in the thickness direction. Specifically, the first elastic limiting plate 370 cooperates with the third surface 410 to limit the position in the thickness direction of the lighting fixture. The connecting plate 380 is connected to the first surface 110 or the second surface 210 so that the bending buckle 300 is arranged on the first surface 110 or the second surface 210. The second elastic limiting plate 390 is laterally limited by the blocking member 130, that is, the second elastic limiting plate 390 and the blocking member 130 are limited in the direction in which the second elastic limiting plate 390 extends toward the blocking member 130.

[0048] During the specific assembly process of the base 100 and the lampshade 200, the first elastic limiting plate 370 and the second elastic limiting plate 390 are elastically deformed, so that the bending buckle 300 can be relatively easily limited and engaged with the third surface 410 and the blocking member 130, respectively. In the process of the first elastic limiting plate 370 and the second elastic limiting plate 390 recovering from deformation, the first elastic limiting plate 370 abuts and contacts the third surface 410, thereby achieving a limit position in the thickness direction, and the second elastic limiting plate 390 abuts and contacts the blocking member 130, thereby achieving a limit position in the direction in which the second elastic limiting plate 390 extends toward the blocking member 130. Of course, the bending buckle 300 may not be an elastic bending buckle, that is, the limiting plate of the bending buckle 300 that is limited and engaged with the third surface 410 is not an elastic limiting plate, and the limiting plate of the bending buckle 300 that is limited and engaged with the blocking member 130 is not an elastic limiting plate.

[0049] In one embodiment, please refer to Figures 16 and 18, the first elastic limiting plate 370 and the second elastic limiting plate 390 can be arranged relative to each other, and the first elastic limiting plate 370 and the second elastic limiting plate 390 both extend toward the base 100 and the lampshade 200 that is connected to the bending buckle 300, that is, at this time, the bending buckle 300 is generally U-shaped.

[0050] In another embodiment, the extension direction of the first elastic limiting plate 370 is opposite to the extension direction of the second elastic limiting plate 390, and the first elastic limiting plate 370 extends toward one of the base 100 and the lampshade 200 connected to the bending buckle 300. At this time, the second elastic limiting plate 390 extends toward the other of the base 100 and the lampshade 200, that is, the second elastic limiting plate 390 extends toward the blocking member 130, so as to cooperate with the blocking member 130 in the direction in which the second elastic limiting plate 390 extends toward the blocking member 130.

[0051] It can be seen from this that in this embodiment, even if the size of the blocking member 130 in the thickness direction of the lighting fixture is relatively small, since the second elastic limiting plate 390 extends toward the blocking member 130, the second elastic limiting plate 390 can easily cooperate with the blocking member 130 to limit the position. At the same time, since the size of the blocking member 130 is relatively small, that is, the material used in the blocking member 130 is relatively small, this can reduce the cost of producing the blocking member 130, thereby reducing the production cost of the lighting fixture.

[0052] In one embodiment, since part of the first connecting member 400 needs to protrude from the first mounting hole 120, at this time, in order to ensure the setting stability of the first connecting member 400, please refer to Figures 11 to 14, an arc-shaped protrusion 140 is also protruded on the first surface 110 or the second surface 210, and the arc-shaped protrusion 140 is arranged around part of the first mounting hole 120, and part of the first connecting member 400 is in contact with the arc-shaped protrusion 140. Specifically, the first connecting member 400 has a third surface 410 facing the first mounting hole 120, and the third surface 410 is the same surface as the third surface 410 described above, and a part of the third surface 410 is in contact with the arc-shaped protrusion 140 so that the arc-shaped protrusion 140 can support the first connecting member 400 to ensure the setting stability of the first connecting member 400.

[0053] At the same time, because a portion of the third surface 410 contacts the arcuate protrusion 140, an escape space 150 can be formed between another portion of the third surface 410, the arcuate protrusion 140, and the first surface 110. That is, another portion of the third surface 410, the arcuate protrusion 140, and the first surface 110 can enclose the escape space 150, and the first end 310 is located within the escape space 150. That is, at this time, the arcuate protrusion 140 can just avoid the bending buckle 300, so that the bending buckle 300 can enter the escape space 150 and cooperate with the third surface 410 in the thickness direction to limit the position. Of course, the arcuate protrusion 140 can also be omitted from the first surface 110 or the second surface 210.

[0054] In one embodiment, referring to Figures 13 and 14, the first connector 400 is provided with a gasket 420, which has a third surface 410. Due to the large size of the gasket 420, the area of ​​the third surface 410 is larger. This makes it easier for the bending buckle 300 to abut against the third surface 410 during the connection between the base 100 and the lampshade 200, that is, it is easier for the bending buckle 300 to engage with the third surface 410 in the thickness direction. Of course, the first connector 400 may also be provided with no gasket 420, that is, only the top of the first connector 400 described above can be used to engage with the bending buckle 300 in a limited position.

[0055] In one embodiment, referring to Figures 12 and 14 , a guide slope 131 is provided at the top of the blocking member 130. During the connection between the base 100 and the lampshade 200, the second end 320 can be guided and engaged with the guide slope 131. The guide slope 131 facilitates the movement of the second end 320 to a position for limiting engagement with the blocking member 130. That is, the guide slope 131 allows the second end 320 to smoothly limit engagement with the blocking member 130 in the direction in which the second end 320 extends toward the blocking member 130. Of course, the top of the blocking member 130 may not have the guide slope 131, that is, the top of the blocking member 130 may be a horizontal surface.

[0056] In one embodiment, the number of the bending clips 300 can be at least two, each bending clip 300 is used to connect the base 100 and the lampshade 200, and each bending clip 300 can be arranged at intervals in the space between the base 100 and the lampshade 200. By connecting the base 100 and the lampshade 200 through multiple bending clips 300, the connection stability of the base 100 and the lampshade 200 can be ensured, and it can further ensure that the base 100 and the lampshade 200 are not easy to disassemble, that is, to avoid human prying open the lighting fixture.

[0057] The above embodiments of this application focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0058] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
