Description

Technical Field

[0001] This application relates to the technical field of lighting devices, and in particular to a downlight body and a downlight. Background Art

[0002] Currently, there are various types of lamps on the market, such as chandeliers, ceiling lights, wall washing lights, etc., and each of them has different characteristics. Among them, as a decorative lamp, a downlight can provide key lighting for a local area and has a good effect of setting off the atmosphere.

[0003] A downlight usually includes a housing, a light source and two spring clips. The downlight can be installed by hanging on the ceiling through the spring clips. The light source is arranged inside the housing. The spring clips need to be fixed to the housing by screws or riveting, resulting in a complex assembly process of the downlight, which in turn leads to inconvenient assembly and a long assembly time, resulting in a high assembly cost of the downlight. Moreover, when the downlight is assembled on the production line, the spring clips cannot be installed by automated equipment and can only be manually installed, resulting in low assembly efficiency. Summary of the Invention

[0004] This application discloses a downlight body and a downlight, which can solve the problems of complex assembly process and low assembly efficiency existing in current lighting fixtures.

[0005] To solve the above technical problems, this application is implemented as follows:

[0006] In a first aspect, an embodiment of this application discloses a downlight body, which is snap-connected to a spring clip. The downlight body includes a first lamp body and a second lamp body connected to each other, wherein:

[0007] The first lamp body and the second lamp body are assembled along the height direction. At least a part of the second lamp body is sleeved on the outer periphery of the first lamp body, and a snap ring receiving space is formed between the second lamp body and the first lamp body. A first engaging portion is arranged in the snap ring receiving space. The spring clip includes a first connecting portion received in the snap ring receiving space. The first connecting portion is provided with a second engaging portion, and the second engaging portion is configured to cooperate with the first engaging portion to fix the first connecting portion in the snap ring receiving space.

[0008] In a second aspect, an embodiment of this application discloses a downlight, which includes a spring clip, a light source module and the above-mentioned downlight body, wherein:

[0009] The light source module is arranged in the downlight body, and the first connecting portion is snap-connected to the snap ring receiving space through the cooperation of the first engaging portion and the second engaging portion.

[0010] The technical solution adopted by this application can achieve the following beneficial effects:

[0011] In the downlight body disclosed in the present application, the first body and the second body are assembled along the height direction of the downlight, and at least a part of the second body is sleeved on the outer periphery of the first body, so as to form a retaining spring accommodation space between the second body and the first body. A first engaging portion is arranged in the retaining spring accommodation space, and a second engaging portion is arranged on the first connecting portion of the spring snap. The second engaging portion is configured to cooperate with the first engaging portion to fix the spring snap in the retaining spring accommodation space. In this case, the spring snap is assembled on the downlight body by a snap connection method, so that the assembly and disassembly process of the spring snap is simple, facilitating the assembly of the downlight, shortening the assembly time, and thus reducing the assembly cost of the downlight. At the same time, when assembling the spring snap, the first connecting portion only needs to move in one direction to extend into the retaining spring accommodation space to complete the assembly of the spring snap. When disassembling the spring snap, the first connecting portion only needs to move in the opposite direction to extend out of the retaining spring accommodation space to complete the disassembly of the spring snap. There is no need for manual judgment during the entire assembly and disassembly process. Therefore, when assembling the downlight on the production line, an automated device can be used to assemble the spring snap, resulting in a relatively high assembly efficiency of the downlight.

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 usually of the same category, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0027] The technical solutions disclosed in each embodiment of the present application will be described in detail below in conjunction with the drawings, specific embodiments and their application scenarios.

[0028] Please refer to Figures 1 to 7 , an embodiment of the present application discloses a downlight lamp body 100. The disclosed downlight lamp body 100 is snap-connected to the spring clip 200 of the downlight to facilitate the assembly of the downlight lamp body 100 and the spring clip 200 by the staff. The disclosed downlight lamp body 100 includes a first lamp body 110 and a second lamp body 120 that are connected to each other.

[0029] Among them, the first lamp body 110 and the second lamp body 120 are assembled along the height direction of the downlight. The first lamp body 110 and the second lamp body 120 can be assembled by snap connection, or by means of threaded connection, welding, hot melting, etc. The first lamp body 110 and the second lamp body 120 can be plastic parts or metal parts. When the first lamp body 110 and the second lamp body 120 are plastic parts, the first lamp body 110 and the second lamp body 120 can be formed by injection molding. When the first lamp body 110 and the second lamp body 120 are metal parts, the first lamp body 110 and the second lamp body 120 can be formed by stamping. In the embodiments of the present application, there are no restrictions on the assembly method, material and forming method of the first lamp body 110 and the second lamp body 120.

[0030] In the embodiments of the present application, at least a part of the second lamp body 120 is sleeved on the outer periphery of the first lamp body 110, so as to form a snap ring receiving space 130 between the second lamp body 120 and the first lamp body 110. A first engaging portion 140 is provided in the snap ring receiving space 130. The spring snap 200 includes a first connecting portion 210 received in the snap ring receiving space 130. The first connecting portion 210 is provided with a second engaging portion 211. The second engaging portion 211 is configured to cooperate with the first engaging portion 140 to fix the spring snap 200 in the snap ring receiving space 130. That is to say, the spring snap 200 includes a first connecting portion 210, and the first connecting portion 210 can enter and exit the snap ring receiving space 130. When the first connecting portion 210 is located in the snap ring receiving space 130, the first engaging portion 140 and the second engaging portion 211 are snap-fitted.

[0031] In the specific installation process, first, the first lamp body 110 and the second lamp body 120 are assembled along the height direction of the downlight, so that at least a part of the second lamp body 120 is sleeved on the outer periphery of the first lamp body 110. Then, the first connecting portion 210 is inserted into the snap ring receiving space 130. After the first connecting portion 210 is inserted into the snap ring receiving space 130, the first engaging portion 140 and the second engaging portion 211 will be snap-fitted, so that the first connecting portion 210 is fixed in the snap ring receiving space 130, thereby assembling the spring snap 200 on the downlight lamp body 100. When the spring snap 200 needs to be disassembled, only a large external force needs to be applied to the first connecting portion 210. The external force will cause the first engaging portion 140 and the second engaging portion 211 to separate, so that the first connecting portion 210 extends out of the snap ring receiving space 130, thereby realizing the disassembly of the spring snap 200.

[0032] In the downlight lamp body disclosed in the present application, the first lamp body 110 and the second lamp body 120 are assembled along the height direction of the downlight, and at least a part of the second lamp body 120 is sleeved on the outer periphery of the first lamp body 110, so as to form a snap ring receiving space 130 between the second lamp body 120 and the first lamp body 110. A first clamping portion 140 is arranged in the snap ring receiving space 130. A second clamping portion 211 is arranged on the first connecting portion 210 of the spring snap 200. The second clamping portion 211 is configured to cooperate with the first clamping portion 140 to fix the spring snap 200 in the snap ring receiving space 130. In this case, the spring snap 200 is assembled on the downlight lamp body 100 by clamping, so that the assembly and disassembly process of the spring snap 200 is simple, the assembly of the downlight is convenient, the assembly time is shortened, and thus the assembly cost of the downlight is reduced. At the same time, when the spring snap 200 is assembled, the first connecting portion 210 only needs to move in one direction to extend into the snap ring receiving space 130, and the assembly of the spring snap 200 can be completed. When the spring snap 200 is disassembled, the first connecting portion 210 only needs to move in the opposite direction to extend out of the snap ring receiving space 130, and the disassembly of the spring snap 200 can be completed. There is no operation that needs to be judged manually during the whole assembly and disassembly process. Therefore, when the downlight is assembled on the production line, an automatic device can be used to assemble the spring snap 200, so that the assembly efficiency of the downlight is relatively high.

[0033] Of course, the spring snap 200 can be first assembled with the first lamp body 110, that is, the first connecting portion 210 is first connected to the outer wall of the first lamp body 110. Specifically, the first connecting portion 210 and the outer wall of the first lamp body 110 can be connected by the clamping cooperation of the first clamping portion 140 and the second clamping portion 211, or can be connected by welding, bonding, hot melting and other methods, or the first connecting portion 210 can be attached to the outer wall of the first lamp body 110 by an external fixing method. Then, the second lamp body 120 is sleeved on the outer periphery of the first lamp body 110, so as to complete the assembly of the downlight; or, the spring snap 200 can also be first assembled with the second lamp body 120, that is, the first connecting portion 210 is first connected to the inner wall of the second lamp body 120. Specifically, the first connecting portion 210 and the inner wall of the second lamp body 120 can be connected by the clamping cooperation of the first clamping portion 140 and the second clamping portion 211, or can be connected by welding, bonding, hot melting and other methods, or the first connecting portion 210 can be attached to the inner wall of the second lamp body 120 by an external fixing method. Then, the first lamp body 110 is assembled to the second lamp body 120, so that at least a part of the first lamp body 110 is sleeved by the second lamp body 120, so as to complete the assembly of the downlight. The specific assembly process of the downlight in the embodiment of the present application is not limited.

[0034] In an alternative embodiment, the first lamp body 110 may include a cover body 111 and an extension portion 112 extending from the cover body 111 towards the second lamp body 120. At least a part of the second lamp body 120 may be sleeved on the outer periphery of the extension portion 112, and a snap ring receiving space 130 may be formed between the extension portion 112 and the second lamp body 120. The extension portion 112 can increase the sleeved area of the second lamp body 120. That is to say, the extension portion 112 can make the sleeved depth of the second lamp body 120 and the first lamp body 110 larger, so that the depth of the snap ring receiving space 130 can be larger, enabling the first connecting portion 210 to be set larger, and further enabling the first connecting portion 210 to be stably fixed in the snap ring receiving space 130. At the same time, the extension portion 112 is not exposed outside the second lamp body 120, so that the appearance of the downlight has a high integrity. It should be noted that the depth of the snap ring receiving space 130 refers to the dimension of the snap ring receiving space 130 in the height direction of the downlight.

[0035] To further improve the stability of the first connecting portion 210 fixed in the snap ring receiving space 130, optionally, both the first lamp body 110 and the second lamp body 120 may be annular members, so that the shape of the snap ring receiving space 130 is arc-shaped, the shape of the first connecting portion 210 may be arc-shaped adapted to the snap ring receiving space 130, and the two opposite arc surfaces of the first connecting portion 210 may be respectively attached to the outer wall surface of the first lamp body 110 and the inner wall surface of the second lamp body 120, so that the outer wall surface of the first lamp body 110 and the inner wall surface of the second lamp body 120 play a role in limiting the first connecting portion 210, preventing the first connecting portion 210 from shaking in the snap ring receiving space 130, and preventing the separation of the first engaging portion 140 and the second engaging portion 211 due to shaking, so that the first connecting portion 210 can be stably fixed in the snap ring receiving space 130, and improving the assembly reliability of the spring snap 200 and the downlight lamp body 100.

[0036] As described above, a first engaging portion 140 is provided in the snap ring receiving space 130. Specifically, the first engaging portion 140 may be provided on either the extension portion 112 or the second lamp body 120. That is to say, the first engaging portion 140 may be provided on the outer wall of the extension portion 112 or on the inner wall of the second lamp body 120. This application embodiment does not limit this.

[0037] Furthermore, the extension portion 112 may integrally extend from the cover body 111 towards the second lamp body 120, so that the first lamp body 110 is an integrally formed part, avoiding light leakage gaps after the extension portion 112 and the cover body 111 are assembled, and preventing poor heat dissipation of the first lamp body 110 due to the existence of light leakage gaps.

[0038] For the convenience of the first connecting portion 210 to extend into or out of the retaining spring receiving space 130, optionally, a sliding groove 150 may be formed in either the extending portion 112 or the second lamp body 120. The first connecting portion 210 may be slidably engaged with the sliding groove 150 in the engaging direction of the first engaging portion 140 and the second engaging portion 211, so that the first connecting portion 210 can extend into or out of the retaining spring receiving space 130 more accurately, facilitating the assembly of the first connecting portion 210, thus facilitating the assembly of the spring buckle 200. Moreover, this method is conducive to the assembly of the spring buckle 200 by automated equipment, thereby further improving the assembly efficiency of the downlight.

[0039] To prevent external impurities (such as dust and water vapor) from easily entering the downlight lamp body 100 through the retaining spring receiving space 130, optionally, the first lamp body 110 may further include a convex edge 113 located at the periphery of the extending portion 112. The convex edge 113 may cover a part of the retaining spring receiving space 130, and the part of the retaining spring receiving space 130 not covered by the convex edge 113 forms an operation opening 114. The operation opening 114 communicates with the retaining spring receiving space 130, and the first connecting portion 210 can enter and exit the retaining spring receiving space 130 through the operation opening 114. The convex edge 113 can block a part of the external impurities, preventing the external impurities from entering the downlight lamp body 100 through the retaining spring receiving space 130, thereby avoiding the external impurities from affecting the stability of the electronic devices in the downlight lamp body 100. At the same time, the operation opening 114 can ensure that the first connecting portion 210 normally extends into or out of the retaining spring receiving space 130.

[0040] Of course, a sealing member may also be provided in the retaining spring receiving space 130. The sealing member may be located at the end of the retaining spring receiving space 130 away from the operation opening 114. This setting method neither affects the normal extension or retraction of the first connecting portion 210 into or out of the retaining spring receiving space 130, nor can it prevent external impurities from entering the downlight lamp body 100.

[0041] Furthermore, the surface of the convex edge 113 facing away from the second lamp body 120 may be coplanar with the surface of the cover body 111 facing away from the second lamp body 120, so that the appearance of the downlight lamp body 100 is relatively flat, improving the appearance integration of the downlight lamp body 100, thereby making the appearance of the downlight lamp body 100 more beautiful.

[0042] The light source module 400 of the downlight is installed inside the downlight body 100. Therefore, a wire routing hole needs to be provided on the downlight body. The wire routing hole can be directly drilled on the downlight body 100. However, this operation needs to be carried out after the downlight body 100 is assembled, which will affect the stability of the assembled downlight body 100. Based on this, in an alternative embodiment, a first notch 1121 can be formed in the extension part 112, a second notch 121 can be formed in the second lamp body 120, and the cable 300 passes through the first notch 1121 and the second notch 121. In this case, after the downlight body 100 is assembled, the first notch 1121 and the second notch 121 are arranged opposite to each other to form a wire routing hole. This method can be set before the downlight body 100 is assembled and the wire routing hole is formed only after assembly, thus preventing the wire routing hole from being directly drilled on the downlight body 100 and avoiding affecting the stability of the assembled downlight body 100. At the same time, the first notch 1121 can be integrally formed by the extension part 112, and the second notch 121 can be integrally formed by the second lamp body 120, avoiding the first notch 1121 or the second notch 121 being formed by a post-processing method and preventing the first notch 1121 or the second notch 121 from affecting the structural reliability of the extension part 112 or the second lamp body 120 during the post-processing.

[0043] Further, the first notch 1121 and the second notch 121 can clamp the cable 300 to better fix the cable 300, avoiding the electrical connection failure between the cable 300 and the light source module 400 caused by pulling the cable 300, thereby improving the stability of the downlight during use.

[0044] In another alternative embodiment, a convex block 115 can be provided at the first notch 1121. An anti-slip structure can be provided on the side of the convex block 115 facing the second notch 121. The second notch 121 and the anti-slip structure can clamp the cable 300 to better fix the cable 300, and the anti-slip structure can cooperate with the surface of the cable 300, making it more difficult for the cable 300 to be pulled and shaken, thereby further improving the stability of the downlight during use.

[0045] As described above, the light source module 400 of the downlight is installed inside the downlight body 100. Specifically, the light source module 400 can be installed on the cover body 111. Optionally, a second connecting part 1111 can be provided on the side of the cover body 111 facing the second lamp body 120. The light source module 400 can be arranged on the cover body 111 through the second connecting part 1111. The second connecting part 1111 can facilitate the installation of the light source module 400, thereby further facilitating the installation of the downlight.

[0046] The second connecting portion 1111 can be a threaded connector or a snap connector. Optionally, the second connecting portion 1111 can be a heat fusion portion. When the light source module 400 needs to be installed, only the heat fusion portion needs to be heated and deformed, and the deformed heat fusion portion can be connected to the heat fusion portion after cooling. This installation method is simpler and more convenient. The heat fusion portion can be a plastic portion, hot melt adhesive, etc.

[0047] In the embodiment of the present application, the second snap portion 211 is configured to cooperate with the first snap portion 140 to fix the spring snap 200 in the snap spring receiving space 130. That is to say, the first snap portion 140 and the second snap portion 211 can be snap-fitted. Optionally, among the first snap portion 140 and the second snap portion 211, one can be a snap projection, and the other can be a snap groove or a snap hole. The snap projection and the snap groove or the snap hole are snap-fitted in the height direction. That is, the first snap portion 140 is a snap projection, and the second snap portion 211 is a snap groove or a snap hole, or the second snap portion 211 is a snap projection, and the first snap portion 140 is a snap groove or a snap hole.

[0048] On the side of the second lamp body 120 facing away from the first lamp body 110, a ring-shaped shielding outer edge 122 formed by extension can be provided. After the downlight is installed on the installation base, the shielding outer edge 122 can shield the installation hole opened on the installation base, improving the aesthetics after the downlight is installed, and thus improving the user experience.

[0049] Based on the downlight lamp body 100 disclosed in the embodiment of the present application, the embodiment of the present application also discloses a downlight, including a spring snap 200, a light source module 400, and the downlight lamp body 100 described in any of the above embodiments, wherein:

[0050] The light source module 400 is disposed in the downlight lamp body 100, and the spring snap 200 is snap-fitted in the snap spring receiving space 130 through the cooperation of the first snap portion 140 and the second snap portion 211. In this case, the spring snap 200 is assembled on the downlight lamp body 100 by snap-fitting, making the assembly and disassembly process of the spring snap 200 simple, facilitating the assembly of the downlight, shortening the assembly time, and thus reducing the assembly cost of the downlight. At the same time, when the downlight is assembled on the production line, an automated device can be used to assemble the spring snap 200, so that the assembly efficiency of the downlight is relatively high.

[0051] Optionally, the downlight may further include a mask 500. The mask 500 may be disposed on the side of the second lamp body 120 facing away from the first lamp body 110, and form an installation space with the downlight lamp body 100. The light source module 400 is disposed in the installation space. The mask 500 can play a role in diffusing light, so that the light emitted by the downlight is evenly irradiated onto the area to be irradiated, thereby improving the lighting effect of the downlight. Optionally, in the embodiments of the present application, the light source module 400 may be an LED (Light Emitting Diode). Optionally, in the embodiments of the present application, the mask 500 may be snap-fitted to the inner wall of the second lamp body 120.

[0052] Of course, the downlight may further include a reflector. The reflector may be disposed in the downlight lamp body 100. The reflector may have an incident light end and an emergent light end disposed opposite to each other. The light source module 400 is located on the side where the incident light end is located. In this solution, the reflector can reflect the light emitted by the light source module 400, play a role in concentrating light, avoid light waste, and thus improve the optical performance of the downlight.

[0053] In order to enable the downlight to be more reliably installed on the installation base and prevent the downlight from falling off easily, optionally, the number of the spring clips 200 may be at least two. At least two spring clips 200 can undoubtedly enable the downlight to be reliably installed on the installation base and prevent the downlight from falling off the installation base. Further, at least two spring clips 200 may be symmetrically arranged so that the downlight is more evenly stressed. This method can also enable the downlight to be reliably installed on the installation base.

[0054] The spring clip 200 may include an installation portion 220, a torsion spring 230, and the first connection portion 210 described in any of the above embodiments. The installation portion 220 may be hinged to the first connection portion 210 through the torsion spring 230. The installation portion 220 may be snap-fitted to the installation base. The structure of such a spring clip 200 is simple and reliable, and is convenient for preparation.

[0055] Further, the position of the first connection portion 210 close to the torsion spring 230 bends and extends in a direction away from the downlight lamp body 100, so as to increase the distance between the first connection portion 210 and the torsion spring 230, that is, the force arm of the first connection portion 210 relative to the torsion spring 230 is larger. Thus, during the installation process of the installation portion 220, under the same torque, the torsion force received by the first connection portion 210 is smaller, avoiding damage to the spring clip receiving space 130 by the first connection portion 210, and further preventing deformation or breakage of the first lamp body 110 or the second lamp body 120.

[0056] In the embodiment of the present application, the shape of the circlip receiving space 130 may be arc-shaped. Therefore, the shape of the first connecting portion 210 also needs to be arc-shaped and adapted to the circlip receiving space 130 to ensure that the first connecting portion 210 can normally extend into or out of the circlip receiving space 130. Moreover, the two arc surfaces of the first connecting portion 210 facing away from each other can be respectively attached to the outer wall surface of the first lamp body 110 and the inner wall surface of the second lamp body 120. The outer wall surface of the first lamp body 110 and the inner wall surface of the second lamp body 120 play a role in limiting the first connecting portion 210, preventing the first connecting portion 210 from shaking in the circlip receiving space 130 and avoiding the separation of the first engaging portion 140 and the second engaging portion 211 caused by the shaking. As a result, the first connecting portion 210 can be stably fixed in the circlip receiving space 130, improving the assembly reliability of the spring buckle 200 and the downlight lamp body 100.

[0057] In the above embodiments of the present application, the differences between the various embodiments are mainly described. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a more optimal embodiment. For the sake of brevity of the description, they will not be elaborated here.

[0058] The above description is only for the embodiments of the present application and is not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
