[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0022] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0023] Next, the embodiments of the present application will be described in detail in conjunction with the accompanying drawings, through specific embodiments and their application scenarios.

[0024] Reference Figures 1 to 6 , an embodiment of the present application discloses a lighting fixture. Among them, the lighting fixture can be a downlight. Of course, it can also be in other forms, and specific limitations are not made here. The disclosed lighting fixture includes a housing 10, a mounting ring 20, and a clamping member 30, as Figure 1 shown.

[0025] The housing 10 is a basic mounting member, which can provide a mounting foundation for components such as the mounting ring 20 and the clamping member 30. Of course, it can also mount the lighting fixture body and dissipate heat for the lighting fixture body. As Figure 2 shown, in some embodiments, the housing 10 has a mounting cavity 11 and an opening 12, and the opening 12 communicates with the mounting cavity 11 to facilitate assembling components such as the lighting fixture body and the mounting ring 20 into the mounting cavity 11 through the opening 12.

[0026] Exemplarily, the mounting cavity 11 provided in the housing 10 is used to mount components such as the lighting fixture body and the mounting ring 20. Considering that the lighting fixture body generates heat during operation, the housing 10 in the embodiment of the present application can have good heat dissipation characteristics. For example, the housing 10 can be made of a material with good thermal conductivity. In addition, the housing 10 can also be provided with a plurality of heat dissipation fins, and the heat transferred from the lighting fixture body to the housing 10 can be dissipated to the air through the plurality of heat dissipation fins, thereby achieving the heat dissipation effect on the lighting fixture body to prevent the entire lighting fixture from being burned out due to excessive temperature. Among them, the housing 10 and the heat dissipation fins can be an integral structure to facilitate shortening the manufacturing cycle.

[0027] Of course, to reduce the size of the lighting fixture in the axial direction, the heat dissipation fins can also extend from the tail end of the housing 10 in a direction perpendicular to the axis. In this way, it can not only ensure that the heat dissipation fins have a large enough heat dissipation area but also reduce the size of the lighting fixture in the axial direction.

[0028] Under actual working conditions, the housing 10 can be assembled to a mounting body, which can be a roof, a ceiling, a wall, etc., and the opening 12 can be opened at the bottom end of the housing 10 to facilitate the lighting fixture body assembled into the mounting cavity 11 to emit light downward to achieve lighting.

[0029] The mounting ring 20 is provided at the opening 12 of the housing 10. To achieve stable installation of the mounting ring 20 and the housing 10, the embodiment of the present application uses a clamping member 30 to clamp and fix the mounting ring 20 and the housing 10, thereby ensuring both installation stability and achieving rapid installation to improve installation efficiency.

[0030] Reference Figure 2 and Figure 3, in some embodiments, the inner wall of the opening 12 may be provided with a first clamping groove 121. Correspondingly, the outer wall of the mounting ring 20 may be provided with a second clamping groove 211, and the clamping member 30 is respectively clamped and matched with the first clamping groove 121 and the second clamping groove 211 to realize the clamping and fixing of the mounting ring 20 and the housing 10.

[0031] Reference Figures 4 to 6 , the clamping member 30 may include a first clamping section 31, which is arranged between the inner wall of the opening 12 and the outer wall of the mounting ring 20 to facilitate clamping the mounting ring 20 to the opening 12. Further, the first clamping section 31 may be provided with a first clamping claw 311 and a second clamping claw 312. Among them, the first clamping claw 311 is clamped and matched with the first clamping groove 121, and the second clamping claw 312 is clamped and matched with the second clamping groove 211. Exemplarily, the number of the first clamping claws 311 may be one or more, and the number of the second clamping claws 312 may be one or more.

[0032] Based on the above settings, when the first clamping claw 311 is clamped and matched with the first clamping groove 121, the clamping and fixing of the clamping member 30 and the housing 10 can be ensured. When the second clamping claw 312 is clamped and matched with the second clamping groove 211, the clamping and fixing of the clamping member 30 and the mounting ring 20 can be ensured. Thus, the clamping and fixing of the mounting ring 20 and the housing 10 is realized through the clamping member 30. Compared with the installation methods using screws or machining threads in the related art, the embodiments of the present application do not need to additionally introduce screws, thereby reducing the structural complexity and being beneficial to reducing costs. Nor do they need to additionally machine threads, thereby simplifying the manufacturing process. Moreover, the clamping method is adopted to replace the screw connection method or the thread connection method, so that the installation of the mounting ring 20 and the housing 10 can be more convenient and fast. Therefore, the clamping method in the embodiments of the present application can improve the installation efficiency, reduce the tediousness, and be beneficial to reducing costs while ensuring the installation stability.

[0033] In some embodiments, in the disassembly direction of the mounting ring 20 relative to the housing 10, the first clamping claw 311 extends obliquely towards the inner wall of the opening 12 from the first clamping section 31 and at least partially extends into the first clamping groove 121, where the disassembly direction is from the inside of the installation cavity 11 towards the opening 12, as Figure 5 and Figure 6 shown. Based on this setting, the clamping and matching of the first clamping claw 311 and the first clamping groove 121 can be realized, so that when the mounting ring 20 is disassembled relative to the housing 10, the first clamping claw 311 is limited by the groove wall of the first clamping groove 121, thereby effectively preventing the mounting ring 20 from detaching from the housing 10.

[0034] Further, the side wall of the end face of the first card slot 121 close to the opening 12 can be perpendicular to the axis of the lamp. In this way, effective blocking of the first claw 311 can be achieved to prevent the first claw 311 from disengaging from the first card slot 121 and causing the engaging member 30 to disengage from the housing 10.

[0035] In addition, the side wall of the end face of the first card slot 121 far from the opening 12 can form a first non-right-angle included angle with the axis of the lamp. The existence of this first included angle makes the side wall arranged in a slope form. In this way, the extending direction of the side wall can be adapted to the extending direction of the first claw 311. Thus, when the engaging member 30 is moved in the direction of assembling with respect to the housing 10, the first claw 311 can be disengaged from the first card slot 121, so as to lay a foundation for disassembling the mounting ring 20.

[0036] Continue to refer to Figure 5 and Figure 6 , in some embodiments, in the assembling direction of the mounting ring 20 with respect to the housing 10, the second claw 312 extends obliquely towards the outer wall of the mounting ring 20 from the first engaging section 31 and at least partially extends into the second card slot 211. Wherein, the assembling direction is the direction from the opening 12 towards the inside of the mounting cavity 11. Based on this setting, the clamping cooperation between the second claw 312 and the second card slot 211 can be realized. In this way, under the clamping action of the engaging member 30, the mounting ring 20 can be effectively prevented from disengaging from the housing 10, ensuring the mounting stability of the mounting ring 20.

[0037] Further, the side wall of the end face of the second card slot 211 far from the opening 12 can form a second non-right-angle included angle with the axis of the lamp. The existence of this second included angle makes the side wall arranged in a slope form. In this way, when the engaging member 30 is pushed into the mounting cavity 11, the end of the second claw 312 can contact and move along this side wall, so that the second claw 312 disengages from the second card slot 211, facilitating the disassembly of the mounting ring 20.

[0038] Refer to Figure 4 and Figure 5 , in some embodiments, the engaging member 30 may further include a second engaging section 32, and the second engaging section 32 is connected to the first engaging section 31. Wherein, the first engaging section 31 and the second engaging section 32 can be fixedly connected. Of course, the entire engaging member 30 can also be an integral structure.

[0039] The second engaging section 32 extends from the opening 12 to the outer peripheral area of the housing 10 and is used for clamping to the mounting body of the lamp. It should be noted here that in actual situations, the lamp can be assembled to the mounting body, such as the roof, ceiling, etc. In the embodiments of the present application, the connection between the lamp and the mounting body can be realized through the second engaging section 32 to ensure the mounting stability of the lamp.

[0040] In some embodiments, the first clamping section 31 of the clamping member 30 may extend along the axis of the lamp so as to be clamped between the outer wall of the mounting ring 20 and the inner wall of the opening 12 of the housing 10. In addition, the angle between the second clamping section 32 and the first clamping section 31 may be an acute angle so that the second clamping section 32 extends both toward the rear end of the lamp and toward the periphery of the lamp, so as to be clamped and matched with the mounting body around the lamp, thereby achieving clamping and fixing of the lamp.

[0041] Furthermore, the connection between the first clamping section 31 and the second clamping section 32 can also be an arc section, which can avoid interference with the end of the shell 10 on the one hand, and can also reduce the stress at the connection on the other hand to alleviate the problem of stress concentration causing the connection to be easily broken.

[0042] In order to prevent the clamping component 30 from detaching from the installation body, a bending section 33 can also be provided at the end of the second clamping section 32 that is away from the first clamping section 31. The bending section 33 forms an obtuse angle with the second clamping section 32 to facilitate clamping cooperation with the installation body, thereby effectively preventing the clamping component 30 from detaching from the installation host and further improving the installation stability of the lamp.

[0043] In some more specific embodiments, the clamping member 30 may be an elastic integrated structure. The clamping member 30 may be an integrated structure to facilitate manufacturing and shorten the manufacturing cycle; the clamping member 30 may also be an elastic member that can produce elastic deformation when subjected to force to facilitate the clamping fit.

[0044] Among them, the first claw 311 and the second claw 312 can both produce elastic deformation relative to the first clamping section 31, so as to be respectively clamped into the first clamping slot 121 and the second clamping slot 211, or detached from the first clamping slot 121 and the second clamping slot 211; the second clamping section 32 can produce elastic deformation, so as to be installed to the installation body.

[0045] Exemplarily, the clamping member 30 can be a spring structure, and of course, it can also be other structures, which are not specifically limited here. In addition, the material of the clamping member 30 can be metal material, plastic material, etc., and of course, it can also be other materials as long as it has elastic properties.

[0046] refer to Figure 1 and Figure 5, in some embodiments, the lamp may include a plurality of snap connectors 30. The plurality of snap connectors 30 are arranged circumferentially along the lamp, and the first claws 311 of the plurality of snap connectors 30 are respectively engaged with the first slots 121 in a snap-fit manner, and the second claws 312 of the plurality of snap connectors 30 are respectively engaged with the second slots 211 in a snap-fit manner. Based on this arrangement, the snap-fit between the mounting ring 20 and the housing 10 can be achieved through the plurality of snap connectors 30, thereby further improving the connection stability between the mounting ring 20 and the housing 10 and preventing the mounting ring 20 from detaching from the housing 10.

[0047] In addition, the second engaging sections 32 of the plurality of snap connectors 30 are respectively engaged with the mounting body in a snap-fit manner. Thus, the connection stability between the lamp and the mounting body can be further improved, and the lamp can be prevented from detaching from the mounting body.

[0048] Exemplarily, the number of snap connectors 30 can be two, three, four, etc. Of course, it can also be other numbers, which are not specifically limited herein.

[0049] To achieve the snap-fit with the plurality of first claws 311, in some embodiments, the inner wall of the opening 12 may be provided with a plurality of first slots 121 arranged circumferentially along the lamp, and the first claw 311 of each snap connector 30 is engaged with the corresponding first slot 121 in a snap-fit manner. Based on this, the snap-fit stability can be ensured through the one-to-one corresponding snap-fit between the first claw 311 and the first slot 121.

[0050] In some other embodiments, the inner wall of the opening 12 may be provided with a first slot 121 arranged circumferentially around the lamp, that is, the first slot 121 may be an annular slot, and the first claws 311 of the plurality of snap connectors 30 are all engaged with the first slot 121 in a snap-fit manner. Based on this, the snap-fit stability can also be ensured through the cooperation of the plurality of first claws 311 with a single integral first slot 121.

[0051] To achieve the snap-fit with the plurality of second claws 312, in some embodiments, the outer wall of the mounting ring 20 may be provided with a plurality of second slots 211 arranged circumferentially along the lamp, and the second claw 312 of each snap connector 30 is engaged with the corresponding second slot 211 in a snap-fit manner. Based on this, the snap-fit stability can be ensured through the one-to-one corresponding snap-fit between the second claw 312 and the second slot 211.

[0052] In some other embodiments, the outer wall of the mounting ring 20 may be provided with a second slot 211 arranged circumferentially around the lamp, that is, the second slot 211 may be an annular slot, and the second claws 312 of the plurality of snap connectors 30 are all engaged with the second slot 211 in a snap-fit manner. Based on this, the snap-fit stability can also be ensured through the cooperation of the plurality of second claws 312 with a single integral second slot 211.

[0053] Reference Figure 2 andFigure 6 In some embodiments, a plurality of limiting grooves 122 may be provided on the inner wall of the opening 12. The plurality of limiting grooves 122 are arranged along the circumferential direction of the lamp. The first clamping segments 31 of the plurality of clamping members 30 are respectively arranged in the plurality of limiting grooves 122, and the limiting grooves 122 are used to limit the corresponding clamping members 30 in the circumferential direction of the lamp. Based on this setting, on the one hand, the first clamping segments 31 of the corresponding clamping members 30 can be accommodated by the limiting grooves 122 to avoid assembly interference between the clamping members 30, the mounting ring 20 and the housing 10. On the other hand, the clamping members 30 can be limited in the circumferential direction of the lamp by the groove walls of the limiting grooves 122 to prevent the clamping members 30 from moving along the circumferential direction of the lamp.

[0054] In addition, the first clamping groove 121 may be provided at the bottom of the corresponding limiting groove 122 to facilitate the clamping of the first clamping claws 311.

[0055] Reference Figure 3 In some embodiments, the mounting ring 20 may include a mounting ring body 21 and a flange 22. The flange 22 is provided at one end of the mounting ring body 21 along the axial direction of the mounting ring 20 and is annularly arranged on the outer wall of the mounting ring body 21. Based on this, when the mounting ring 20 is assembled, the mounting ring body 21 can be assembled to the opening 12 of the housing 10, and the mounting ring body 21 can be clamped to the opening 12 by the clamping member 30. In the embodiments of the present application, the second clamping groove 211211 is provided on the outer wall of the mounting ring body 21.

[0056] In addition, when the lamp is assembled to the mounting main body, the housing 10 is located above or inside the mounting main body, while the flange 22 of the mounting ring 20 is located below or outside the mounting main body and abuts against the bottom end surface of the mounting main body. In this way, the lamp can be limited to prevent the lamp from entering above or inside the mounting main body, thereby ensuring the installation stability of the lamp.

[0057] Considering that the first clamping segment 31 of the clamping member 30 is located between the outer wall of the mounting ring 20 and the inner wall of the opening 12, and the second clamping segment 32 of the clamping member 30 extends to the outer periphery of the housing 10. To prevent the clamping member 30 from affecting the assembly of the mounting ring 20 and the housing 10, in the embodiments of the present application, a notch 13 may be provided at one end of the housing 10 provided with the opening 12. The clamping member 30 extends from the opening 12 to the outer peripheral area of the housing 10 through the notch 13. In this way, the clamping member 30 can be avoided through the notch 13 to ensure that there is no gap between the end of the housing 10 provided with the opening 12 and the flange 22, and ensure that the mounting ring 20 and the housing 10 are assembled in place. Moreover, the side wall of the notch 13 can limit the clamping member 30 to prevent the clamping member 30 from moving randomly in the circumferential direction and the axial direction of the lamp, as Figure 2 and Figure 5 shown.

[0058] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative rather than restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them fall within the protection scope of the present application.
