Description

Technical Field

[0001] This application belongs to the field of lighting equipment technology, and more specifically, relates to a lamp frame and a surface-mounted lamp assembly. Background Technology

[0002] Surface-mounted lighting fixtures are simple and flexible to install, suitable for ceilings of various thicknesses, and can be quickly disassembled for maintenance. They can also accommodate ceilings with thicknesses from 3mm to 25mm. The light source is hidden inside the building decoration, resulting in a softer visual effect. In addition, surface-mounted lighting fixtures are also suitable for scenarios such as offices that require frequent switching, and are suitable for lighting needs that require a fast response.

[0003] Existing surface-mounted lighting solutions require the use of a surface-mount frame, typically a U-shaped frame fixed to the ceiling. The light fixture is pushed into the frame through an opening, and finally, the edge banding is snapped into the open side of the U-shaped frame. The edge banding and the frame are usually connected via an interference fit (e.g., using spring clips). Assembly requires a certain amount of pushing force to ensure proper placement. This interference fit often results in uneven gaps between the edge banding and the frame, necessitating repeated adjustments to achieve a uniform and aesthetically pleasing gap. This process makes high-altitude installation difficult and hinders installation efficiency. Utility Model Content

[0004] The purpose of this application is to provide a lamp frame and surface-mounted lamp assembly, which aims to solve the problem that the assembly of edge-sealing profiles and surface-mounted frame brackets is difficult and the installation efficiency is hard to improve in existing surface-mounted lamp solutions.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, embodiments of this application provide a lamp frame, comprising:

[0007] The main frame is a U-shaped frame with an opening along a first direction. The rear side of the main frame is connected to the base. The opposite sides of the two arms of the main frame respectively form main slide grooves that allow the side edges of the lamp body to slide into. The main slide grooves are provided with main guide rails extending along the first direction, wherein the first direction is perpendicular to the front and rear direction.

[0008] The main magnetic suction component is fixed inside the main sliding groove;

[0009] A closed frame is provided on the open side of the main frame;

[0010] Two sets of first frame magnetic components are fixed to the opposite ends of the closed frame respectively. The first frame magnetic components can be inserted into the main slide groove and are in clearance fit with the main slide groove. The first frame magnetic components can be magnetically connected to the main magnetic component after being inserted into the main slide groove.

[0011] The opposite side of the first frame magnetic member is provided with a guide groove that slides with the main guide rail. The main guide rail is slidably inserted into the guide groove along the first direction. The width of the guide groove gradually decreases along the first direction, and the width of the small end of the guide groove is not less than the width of the main guide rail.

[0012] Compared with the prior art, the solution shown in this application involves first installing the main frame pre-installed with the main magnetic component onto the base during lamp installation. Then, the two side edges of the lamp body are aligned with the corresponding main sliding grooves, and the lamp body is pushed into the main frame. Next, the closed frame of the pre-installed first frame magnetic component is aligned with the opening of the main frame, allowing the first frame magnetic components at both ends to be inserted into the main sliding grooves. During the insertion of the first frame magnetic component, the main guide rail enters from the larger end of the guide groove. Since the guide groove has a tapered guide structure, as the first frame magnetic component gradually penetrates deeper into the main sliding groove, the main guide rail engages with the side wall of the guide groove, adjusting the position of the first frame magnetic component. This allows the first frame magnetic component to gradually align the closed frame. Once the first frame magnetic component and the main magnetic component are attracted and fixed, the closed frame and the main frame are joined. Pulling the closed frame in the opposite direction separates the first frame magnetic component from the main magnetic component. After the first frame magnetic component detaches from the main sliding groove, the detachment of the closed frame from the main frame is complete.

[0013] The lighting fixture frame of this application can bring the following beneficial effects:

[0014] 1. Because the first frame magnetic component and the main slide are fitted with a clearance during the assembly process, and are finally fixed by the magnetic attraction between the main magnetic component and the first frame magnetic component, there is no interference fit during the assembly process. This effectively avoids the need to apply a large pushing force for interference fit. Furthermore, the magnetic attraction between the main magnetic component and the first frame magnetic component provides the driving force for insertion, enabling automatic adhesion and tightening, thus solving the problem of the inconvenience of high-altitude operations.

[0015] 2. Due to the use of guide grooves whose width gradually decreases along the first direction, as the insertion depth increases, the first frame magnetic component, under the combined action of the main guide rail, gradually aligns the closed frame with the main frame. After insertion, it is fixed by magnetic attraction, and a pulling force is applied in the opposite direction to pull out the closed frame. The closed frame does not need to be precisely aligned with the main frame before insertion, achieving automatic alignment during insertion, effectively reducing assembly difficulty and thus reducing the difficulty of high-altitude operations. Simultaneously, the magnetic connection not only meets the assembly requirements of the closed frame and the main frame, eliminating assembly steps such as locking screws, but also simplifies the assembly structure between the closed frame and the main frame, simplifying the operation of locking the closed frame position, effectively improving assembly efficiency and reducing the difficulty of high-altitude operations. Furthermore, because magnetic assembly is used, the magnetic attraction between the first frame magnetic component and the main magnetic component does not require precise alignment, lowering the requirements for manufacturing and assembly errors, which not only reduces the difficulty of high-altitude operations but also reduces production costs.

[0016] Overall, the lighting frame of this application, with its guiding alignment structure (i.e., the structure formed by the cooperation of the guide groove and the main guide rail), achieves locking of the closed frame and the main frame through magnetic attraction, which reduces assembly difficulty, improves installation efficiency, and is more friendly to high-altitude operation scenarios.

[0017] In conjunction with the first aspect, in one possible implementation, the closed frame is provided with a first frame limiting groove on the side facing the main frame, the first frame limiting groove can accommodate the corresponding side edge of the lamp body, and the first frame magnetic component includes a first connecting frame, a guide frame and a suction part;

[0018] The first connecting frame is fitted and connected to the inner wall of the first frame limiting groove;

[0019] The guide frame is connected to the side of the first connecting frame near the end of the closed frame and extends in a direction opposite to the first direction, forming the guide groove;

[0020] The suction part is connected to the extension end of the guide frame and can be magnetically connected to the main magnetic suction component.

[0021] In conjunction with the first aspect, in one possible implementation, the main magnetic component includes a first magnetic connecting bracket and a first magnetic component. The first magnetic connecting bracket has a main mounting limiting groove that can accommodate the main guide rail. The first magnetic connecting bracket is fitted and connected to the main guide rail, and the displacement of the first magnetic connecting bracket in the front-rear direction is limited by the main mounting limiting groove.

[0022] The first magnetic connection bracket has a magnetic mounting portion extending away from the main guide rail. The first magnetic member is fitted and connected to the magnetic mounting portion, and the first magnetic member can be magnetically connected to the first frame magnetic member.

[0023] In conjunction with the first aspect, in one possible implementation, the lamp frame further includes a lamp limiting member, which is rotatably connected to the support arm of the main frame and the axis of rotation is parallel to the first direction. The lamp limiting member is disposed near the opening side of the main frame and has a limiting state and an avoidance state.

[0024] If the lamp limiting member is in a limiting state, then on a plane perpendicular to the first direction, the orthographic projection of the lamp limiting member at least partially overlaps with the orthographic projection of the lamp body, so as to limit the displacement of the lamp body in the first direction.

[0025] If the lamp limiting member is in the avoidance state, then on the plane perpendicular to the first direction, the orthographic projection of the lamp limiting member and the orthographic projection of the lamp body are misaligned with each other, so that the lamp body can enter and exit the main frame.

[0026] In some embodiments, the lamp frame further includes two sets of main mounting brackets that can be connected to the base. The two sets of main mounting brackets are respectively connected to the rear side of the corresponding support arm. The lamp limiting member is disposed between the two support arms and is rotatably connected to the main mounting bracket on the corresponding side.

[0027] In some embodiments, the main frame includes a connecting frame and two side frames, the two side frames being connected to both ends of the connecting frame to form a U-shaped frame, and the side frames forming the main groove;

[0030] The lamp limiting component includes a main limiting plate and a toggle plate. The main limiting plate is rotatably connected to the limiting mounting part, and the plate surface is perpendicular to the first direction. The toggle plate is located at the swing end of the main limiting plate and extends toward the side where the closed frame is located.

[0031] If in a limited position, the orthographic projection of the main limiting plate and the orthographic projection of the lamp body overlap at least partially on a plane perpendicular to the first direction, and the rotating limiting plate abuts against the edge of the main limiting plate to limit the angle of rotation of the main limiting plate in the second direction, wherein the second direction is perpendicular to the first direction and the front-back direction.

[0032] If in a non-positioned state, the orthographic projection of the main limiting plate and the orthographic projection of the lamp body are misaligned on a plane perpendicular to the first direction.

[0033] In conjunction with the first aspect, in one possible implementation, the bottom of the main slide is provided with cascading holes.

[0034] Secondly, this application embodiment also provides a surface-mounted lighting assembly, including a lighting body and the aforementioned lighting frame, wherein the side edge of the lighting body is slidably inserted into the main slide groove on the corresponding side of the lighting frame.

[0035] Compared with the prior art, the solution shown in this application has lower assembly difficulty and improved installation efficiency by adopting the above-mentioned surface-mounted lighting assembly, making it more suitable for high-altitude operation scenarios.

[0053] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0054] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0055] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a number" means two or more, unless otherwise explicitly specified.

[0056] Please refer to the following: Figures 1 to 14 The lighting frame provided in this application will now be described. The lamp frame includes a main frame 100, a main magnetic 200, a closed frame 300, and two sets of first frame magnetic 400. The main frame 100 is a U-shaped frame with an opening along a first direction. The rear side of the main frame 100 is connected to the base. The opposite sides of the two arms 101 of the main frame 100 respectively form main slide grooves 102 that allow the side edges of the lamp body 700 to slide into. The main slide grooves 102 are provided with main guide rails 103 extending along the first direction, which is perpendicular to the front-back direction. The main magnetic 200 is fixed in the main slide grooves 102. The closed frame 300 is located on the opening side of the main frame 100. The two sets of first frame magnetic 400 are respectively fixed at opposite ends of the closed frame 300. The first frame magnetic 400 can be inserted into the main slide grooves 102 and is clearance-fitted with the main slide grooves 102. The first frame magnetic 400 can be magnetically connected to the main magnetic 200 after being inserted into the main slide grooves 102. The opposite side of the first frame magnetic suction member 400 is provided with a guide groove 401 that slides with the main guide rail 103. The main guide rail 103 is slidably inserted into the guide groove 401 along the first direction. The width of the guide groove 401 gradually decreases along the first direction, and the width of the small end of the guide groove 401 is not less than the width of the main guide rail 103.

[0057] It should be understood that the term "rear" refers to the side of the luminaire frame or luminaire body 700 facing the base, while the term "front" refers to the side of the luminaire frame or luminaire body 700 away from the base. In this embodiment, the base can be a ceiling, roof beam, or other structure that meets the requirements for ceiling-mounted luminaire installation; it is not a unique limitation.

[0058] In this embodiment, the lamp body 700 can be a direct-lit panel lamp (such as...). Figure 1 As shown in the diagram, other lighting fixtures with similar installation requirements, such as side-emitting panel lights, will not be listed here. Therefore, the position of the main guide rail 103 within the main slide groove 102 is related to the outer periphery of the lighting fixture body 700. Figure 1 Taking the shape of the lamp body 700 as an example, the lamp body 700 includes a lamp housing 710 and a lamp frame 720. The lamp frame 720 is located on the front side of the lamp housing 710, and all four sides of the lamp frame 720 protrude from the lamp housing 710. Based on this, the main guide rail 103 is located in the middle of the main slide groove 102, and a slide channel is formed between the main guide rail 103 and the front side wall of the main slide groove 102, allowing the lamp frame 720 to be inserted. The lamp housing 710 is located in the open area enclosed by the main frame 100, such as... Figure 2As shown. Of course, depending on the different shapes of the lamp body 700, alternative solutions can be adopted, such as "a slide that allows the lamp frame 720 to be inserted is formed between the main guide rail 103 and the rear side wall of the main slide groove 102", and "slides that allow the lamp frame 720 to be inserted are formed between the main guide rail 103 and the front side wall of the main slide groove 102, and between the main guide rail 103 and the rear side wall of the main slide groove 102". These solutions will not be listed here.

[0059] It should be understood that if a slide is formed between the main guide rail 103 and the front side wall of the main slide groove 102, allowing the lamp frame 720 to be inserted, the sliding adaptation area between the main frame 100 and the lamp body 700 can be moved forward, and the rear of the main frame 100 can accommodate more of the lamp body 700, thereby compressing the overall assembly size in the front-back direction and avoiding a feeling of oppression after assembly.

[0060] In this embodiment, the front side of the closed frame 300 is flush with the front side of the main frame 100, and the outer periphery of the closed frame 300 and the outer periphery of the main frame 100 form a continuous quadrilateral, thereby ensuring the aesthetics of the assembly. Optionally, the free ends of the main frame 100 support arms 101 and the two ends of the closed frame 300 are respectively provided with mating bevels. The mating bevels of the main frame 100 support arms 101 abut against the mating bevels of the closed frame 300, and the two are assembled to form a beveled seam, which facilitates the connection and helps maintain the aesthetics.

[0061] In this embodiment, the width of the main guide rail 103 in the front-to-back direction remains consistent in the first direction so as to facilitate guidance in conjunction with the guide groove 401.

[0062] The installation process of the lamp frame in this application is exemplified as follows: When installing the lamp, first install the main frame 100 pre-installed with the main magnetic component 200 onto the base, then align the two sides of the lamp body 700 with the corresponding main slide grooves 102, and push the lamp body 700 into the main frame 100. Then, the closed frame 300, pre-installed with the first frame magnetic 400, is aligned with the opening of the main frame 100, so that the first frame magnetic 400 at both ends is inserted into the main slide groove 102 respectively. During the insertion of the first frame magnetic 400, the main guide rail 103 enters from the large end of the guide groove 401. Since the guide groove 401 is a tapered guide structure, as the first frame magnetic 400 gradually penetrates into the main slide groove 102, the main guide rail 103 cooperates with the side wall of the guide groove 401 to adjust the position of the first frame magnetic 400, so that the first frame magnetic 400 drives the closed frame 300 to gradually align. When the first frame magnetic 400 is attracted and fixed with the main magnetic 200, the closed frame 300 and the main frame 100 are spliced ​​together. Pulling the closed frame 300 in the opposite direction will separate the first frame magnetic 400 from the main magnetic 200. After the first frame magnetic 400 is disengaged from the main slide groove 102, the closed frame 300 and the main frame 100 can be disassembled.

[0063] The lamp frame provided in this application has the following advantages compared with the prior art:

[0064] 1. Since the first frame magnetic chuck 400 and the main slide 102 are fitted with a clearance during the assembly process, and are finally fixed by the magnetic attraction between the main magnetic chuck 200 and the first frame magnetic chuck 400, there is no interference fit during the assembly process. This effectively avoids the need to apply a large pushing force for interference fit. Furthermore, the magnetic attraction between the main magnetic chuck 200 and the first frame magnetic chuck 400 provides the driving force for insertion, enabling automatic adhesion and tightening, thus solving the problem of the inconvenience of high-altitude operations.

[0065] 2. Due to the use of guide grooves 401 whose width gradually decreases along the first direction, as the insertion depth increases, the first frame magnetic chuck 400, under the combined action of the main guide rail 103, gradually aligns the closed frame 300 with the main frame 100. After insertion, it is fixed by magnetic attraction, and the closed frame 300 can be pulled out by applying a pulling force in the opposite direction. The closed frame 300 does not need to be precisely aligned with the main frame 100 before insertion, and can achieve automatic alignment during the insertion process, effectively reducing assembly difficulty and thus reducing the difficulty of high-altitude operations. At the same time, the connection achieved by magnetic attraction not only meets the assembly requirements of the closed frame 300 and the main frame 100, but also eliminates assembly steps such as locking screws, and eliminates the need for additional locking structures and locking parts. The assembly structure between the closed frame 300 and the main frame 100 is simplified, and the operation of locking the position of the closed frame 300 is also simplified, effectively improving assembly efficiency and reducing the difficulty of high-altitude operations. In addition, since the assembly is achieved by magnetic attraction, the magnetic attraction between the first frame magnetic component 400 and the main magnetic component 200 does not require precise alignment, which reduces the requirements for manufacturing and assembly errors. This not only reduces the difficulty of high-altitude operations but also reduces production costs.

[0066] Overall, the lighting frame of this application, with the premise of having a guide alignment structure (i.e., the structure formed by the cooperation of the guide groove 401 and the main guide rail 103), achieves the locking of the closed frame 300 and the main frame 100 by magnetic attraction, which reduces the assembly difficulty, improves the installation efficiency, and is more friendly to high-altitude operation scenarios.

[0067] In some embodiments, the closed frame 300 has a first frame limiting groove on the side facing the main frame 100. The first frame limiting groove can accommodate the corresponding side edge of the lamp body 700, further increasing the support on the side of the closed frame 300 based on the two arms 101 of the main frame 100, thereby improving the reliability of the lamp assembly. Based on this, see [reference]. Figure 2 , Figure 7 and Figure 8 The first frame magnetic chuck 400 includes a first connecting frame 410, a guide frame 420, and a suction part 430. The first connecting frame 410 is fitted and connected to the inner wall of the first frame limiting groove. The guide frame 420 is connected to the side of the first connecting frame 410 near the corresponding end of the closed frame 300 and extends in a direction opposite to the first direction, forming a guide groove 401. The suction part 430 is connected to the extended end of the guide frame 420 and can be magnetically connected to the main magnetic chuck 200. The overall structure of the first frame magnetic chuck 400 in this embodiment is reasonably designed, which not only realizes the connection with the closed frame 300, but also meets the requirements of forming the guide groove 401 and corresponding with the main magnetic chuck 200, taking into account both functional integration and structural simplification.

[0068] More specifically, the main magnetic accumulator 200 has a permanent magnet (e.g., a neodymium iron boron magnet), while the attraction part 430 is a ferromagnetic component (e.g., an iron component or an iron-nickel alloy component). To reduce the manufacturing difficulty of the first frame magnetic accumulator 400, the first connecting frame 410, the guide frame 420, and the attraction part 430 are made of the same material and are integrally formed. In this embodiment, the first frame magnetic accumulator 400 is prepared by integral stamping of a metal sheet. The overall structure of the first frame magnetic accumulator 400 is relatively thin and light, which not only meets the usage requirements but also achieves a compact design.

[0069] In some specific embodiments, see Figure 2 and Figure 3 The first frame limiting groove is provided with a first frame protrusion. The first frame protrusion extends along the length direction of the first frame limiting groove, and the first frame protrusion and the first frame limiting groove form an accommodating space that can accommodate the edge of the lamp body 700 (specifically the lamp frame 720). The specific distribution of the accommodating space is referred to the slide formed by the cooperation of the main guide rail 103 and the main slide groove 102, and will not be described again here.

[0070] Based on the first frame protrusion, the first connecting bracket 410 has a first connecting limiting groove 411 that can accommodate the first frame protrusion. The first connecting limiting groove 411 can cooperate with the first frame protrusion to limit the displacement of the first connecting bracket 410 in the front-back direction, thereby enabling the first connecting bracket 410 to be aligned with the mounting position on the first frame protrusion more quickly. At the same time, it can also improve the assembly reliability and prevent the first connecting bracket 410 from falling off.

[0071] In this embodiment, the fitting connection between the first connecting bracket 410 and the first frame protrusion includes, but is not limited to, connection by threaded connectors, connection by rivets, bonding by adhesive, and snap-fit ​​connection, etc., which will not be listed here. The figure exemplarily shows a scheme in which through holes are provided on the first frame protrusion and the first connecting bracket 410, and the connection is made by threaded connectors.

[0072] With the first frame protrusion provided, the end of the first frame protrusion can abut against the corresponding end of the main guide rail 103, increasing the abutment and limiting area between the closed frame 300 and the main frame 100, improving the reliability of the closed frame 300 after assembly, and ensuring the assembly appearance.

[0073] In some embodiments, see Figure 2 and Figure 6The main magnetic component 200 includes a first magnetic connection bracket 210 and a first magnetic component 220. The first magnetic connection bracket 210 has a main mounting limiting groove 211 that can accommodate the main guide rail 103. The first magnetic connection bracket 210 is in close contact with the main guide rail 103, and the displacement of the first magnetic connection bracket 210 is limited in the front-back direction by the main mounting limiting groove 211. The first magnetic connection bracket 210 has a magnetic mounting portion 212 that extends away from the main guide rail 103. The first magnetic component 220 is in close contact with the magnetic mounting portion 212, and the first magnetic component 220 can be magnetically connected to the first frame magnetic component 400. In this embodiment, the first magnetic connection bracket 210 is functionally divided into regions. The portion with the main mounting limiting groove 211 is used to achieve a close connection with the main guide rail 103, while the magnetic mounting part 212 is used to install the first magnetic component 220. The layout is reasonable, taking into account both the integration of functions and the simplification of the structure. This minimizes the space occupied by the first magnetic connection bracket 210 within the main slide groove 102, avoiding interference with the installation of the lamp body 700. In this embodiment, the first magnetic component 220 is a permanent magnet (e.g., a neodymium iron boron magnet).

[0074] In this embodiment, the connection methods between the first magnetic component 220 and the first magnetic connection bracket 210 include, but are not limited to, bonding, riveting, connection via threaded connectors, and connection via snap-fit ​​or spring clips, etc., and are not limited to a single method. Figure 2 An exemplary embodiment is shown in the example, employing a connection via threaded fasteners.

[0075] Optionally, to reduce the manufacturing difficulty of the first magnetic connection bracket 210, the first magnetic connection bracket 210 is integrally formed using a metal sheet stamping process. This results in a relatively thin and lightweight structure, which not only meets usage requirements but also achieves a compact design. The first magnetic connection bracket 210 can be implemented using, but is not limited to, a stainless steel bracket.

[0076] In existing surface-mounted lighting solutions, during the installation of the luminaire into the mounting frame, while waiting for the installation of the edge-sealing profile, and during the process of removing the edge-sealing profile to remove the luminaire for maintenance, the luminaire may slip out of the mounting frame due to vibration, misoperation, or other factors. In severe cases, this could cause the luminaire to fall, posing a safety hazard. To address this issue, in some embodiments, see [reference needed]. Figure 2 and Figure 5The lamp frame also includes a lamp limiting member 500, which is rotatably connected to the support arm 101 of the main frame 100, and the axis of rotation is parallel to the first direction. The lamp limiting member 500 is disposed near the opening side of the main frame 100 and has a limiting state and an avoidance state. If the lamp limiting member 500 is in the limiting state, the orthographic projection of the lamp limiting member 500 and the orthographic projection of the lamp body 700 overlap at least partially in the plane perpendicular to the first direction, so as to restrict the displacement of the lamp body 700 in the first direction. If the lamp limiting member 500 is in the avoidance state, the orthographic projection of the lamp limiting member 500 and the orthographic projection of the lamp body 700 are misaligned in the plane perpendicular to the first direction, so that the lamp body 700 can enter and exit the main frame 100.

[0077] When it is necessary to remove or place the lamp body 700 from the main frame 100, the lamp limiting member 500 is in a non-obstructing state, allowing the lamp body 700 to enter and exit the main frame 100. After the lamp body 700 slides into the main frame 100, the lamp limiting member 500 is rotated and switched from the non-obstructing state to the limiting state. At this time, the lamp limiting member 500 blocks the lamp body 700 from the opening side of the main frame 100, preventing the lamp body 700 from sliding out of the main frame 100 even without the closed frame 300 installed. By setting the lamp limiting member 500, the problem of the lamp body 700 slipping out of the main frame 100 is effectively avoided, improving the safety of assembly and maintenance.

[0078] It should be noted that, of the two support arms 101 of the main frame 100, the lamp limiting member 500 may be provided on only one of the support arms 101, or the lamp limiting member 500 may be provided on both support arms 101; this embodiment exemplarily shows an embodiment in which the lamp limiting member 500 is provided on only one of the support arms 101. In addition, the lamp limiting member 500 is mainly used to block and limit the side of the lamp body 700 near the opening side of the main frame 100 when the lamp body 700 is inside the main frame 100. In order to facilitate the provision of the lamp limiting member 500 on the main frame 100, the lamp limiting member 500 may contact the lamp rear shell.

[0079] In some embodiments, see Figure 2 The lamp frame also includes two sets of main mounting brackets 600 that can be connected to the base. The two sets of main mounting brackets 600 are respectively connected to the rear side of the corresponding support arm 101. The lamp limiting member 500 is disposed between the two support arms 101 and is rotatably connected to the main mounting bracket 600 on the corresponding side. In this embodiment, by setting the main mounting brackets 600, the connection position between the main frame 100 and the base is moved outward, avoiding the need to set related mounting holes on the main frame 100, reducing the area of ​​the openings on the frame, and preventing the opening area from being too large and affecting the structural strength of the main frame 100.

[0080] Optionally, the thickness of the main frame 100 and the closed frame 300 in the front-to-back direction is greater than the thickness of the lamp body 700. After installation, the main frame 100 and the closed frame 300 can fully enclose the lamp body 700, which helps to improve aesthetics. Based on this, the main mounting bracket 600 can adopt a roughly flat design, thereby further reducing the thickness of the lamp frame in the front-to-back direction.

[0081] More specifically, since the main mounting bracket 600 adopts a flat plate design, in order to improve the structural strength of the main mounting bracket 600, a main reinforcing rib 610 is provided on the main mounting bracket 600. At least one main bracket mounting hole 601 is provided on the main reinforcing rib 610. The main mounting bracket 600 can be connected to the base through fasteners that pass through the main bracket mounting hole 601.

[0082] More specifically, since the main mounting bracket 600 adopts a flat plate design, in order to improve the structural strength of the main mounting bracket 600, a reinforcing flange 620 is provided on the edge of the main mounting bracket 600.

[0083] Based on the above embodiments, see Figure 2 and Figure 3 The main frame 100 includes a connecting frame 110 and two side frames 120. The two side frames 120 are connected to both ends of the connecting frame 110 to form a U-shaped frame. The side frames 120 form a main slide groove 102. The main mounting bracket 600 is connected to the connecting frame 110 and the corresponding side frames 120. In this embodiment, the main frame 100 is set up in parts, and the lengths of the connecting frame 110 and the two side frames 120 can be flexibly adjusted according to the size of the lamp body 700. The lengths of each part are determined before splicing, which makes it more flexible to use.

[0084] In this embodiment, the connecting frame 110 and the side frame 120 are connected by means of adhesive bonding, welding, or auxiliary component assembly. In order to achieve the purpose of aesthetics and convenient assembly, the ends of the connecting frame 110 and the side frame 120 are respectively provided with mating bevels, and the mating bevel of the connecting frame 110 abuts against the mating bevel of the side frame 120.

[0085] In some specific embodiments, see Figure 2 , Figure 4 and Figure 9 The connecting frame 110 has a second frame protrusion 111 on the side facing the closed frame 300. The second frame protrusion 111 extends along the long axis of the connecting frame 110 and has a hollow structure. The main guide rail 103 also has a hollow structure. The main frame 100 also includes a corner connector 130, which has two corner arms that are respectively inserted into the cavities of the second frame protrusion 111 and the main guide rail 103.

[0086] Optional, see below Figure 9 The corner joint arm includes an interconnected insertion section 131 and a positioning section 132. The insertion sections 131 of the two corner joint arms are interconnected, and the width of the insertion section 131 is greater than the width of the positioning section 132. The outer surface of the positioning section 132 is flush with the outer surface of the insertion section 131. The insertion section 131 is interference-fitted with the cavity of the second frame protrusion 111 or the cavity of the main guide rail 103, and the outer surface of the positioning section 132 abuts and limits the movement against the outer surface of the cavity of the second frame protrusion 111 or the outer surface of the cavity of the main guide rail 103. In this embodiment, the term "outer surface" refers to the side facing away from the open area in the middle of the main frame 100.

[0087] In some specific embodiments, see Figure 2 and Figure 4 A second frame limiting groove 112 is formed inside the connecting frame 110. The second frame limiting groove 112 can accommodate the edge of the corresponding side of the lamp body 700. It cooperates with the main slide groove 102 and the first frame limiting groove to support the lamp body 700 around its perimeter, making the lamp body 700 more evenly stressed and the installation more stable.

[0088] Optionally, the second frame protrusion 111 extends along the length direction of the second frame limiting groove 112, and the second frame protrusion 111 and the second frame limiting groove 112 form an accommodating space that can accommodate the edge of the lamp body 700 (specifically the lamp frame 720). The specific distribution of this accommodating space is referred to the slide formed by the cooperation of the main guide rail 103 and the main slide groove 102, and will not be described again here.

[0089] Optionally, the main mounting bracket 600 extends into the main slide groove 102 and the second frame limiting groove 112, and is fitted and connected to the rear sidewall of the main slide groove 102 and the second frame limiting groove 112 by means of bonding, threaded fastener connection, etc., thereby realizing the connection with the side frame 120 and the connecting frame 110.

[0090] In some embodiments, see Figure 2 and Figure 10The main mounting bracket 600 has a limiting mounting part 630 on one side near the closed frame 300, and a rotating limiting plate 631 is provided on one side of the limiting mounting part 630. The limiting mounting part 630 extends forward. The lamp limiting component 500 includes a main limiting plate 510 and a toggle plate 520. The main limiting plate 510 is rotatably connected to the limiting mounting part 630, and the plate surface is perpendicular to the first direction. The toggle plate 520 is provided at the swing end of the main limiting plate 510 and extends toward the side where the closed frame 300 is located. If in a limited position, the orthographic projection of the main limiting plate 510 and the orthographic projection of the lamp body 700 at least partially overlap on a plane perpendicular to the first direction, and the rotating limiting plate 631 abuts against the edge of the main limiting plate 510 to limit the angle of rotation of the main limiting plate 510 in a second direction, wherein the second direction is perpendicular to the first direction and the front-back direction; if in a non-positioned position, the orthographic projection of the main limiting plate 510 and the orthographic projection of the lamp body 700 are misaligned on a plane perpendicular to the first direction. In this embodiment, the assembly position of the lamp limiting component 500 is set on the main mounting bracket 600, making full use of the empty space inside the main frame 100, avoiding setting too many connecting structures on the main frame 100, avoiding weakening the structural strength of the main frame 100, and at the same time, it can also make the lamp limiting component 500 closer to the middle of the corresponding side of the lamp body 700, improving the reliability of the limiting. In addition, in this embodiment, the lamp limiting member 500 is set up separately. Under the premise that the limiting function is met by the main limiting plate 510, the position of the main limiting plate 510 can be easily adjusted by the toggle plate 520, thereby improving the ease of use.

[0091] It should be noted that the rear sides of the main frame 100 and the closed frame 300 both protrude from the rear side of the lamp body 700, resulting in a certain gap between the main mounting bracket 600 and the lamp body 700. The main limiting plate 510 corresponds to this gap when in the avoidance state, thereby avoiding interference with the lamp even when in the avoidance state.

[0092] In some more specific embodiments, see Figure 5 The lighting fixture limiting member 500 also includes an auxiliary limiting plate 530, which is located on one side edge of the main limiting plate 510 and is set at an angle to the main limiting plate 510. If the lighting fixture limiting member 500 is in a non-positioned state, the auxiliary limiting plate 530 abuts against the edge of the limiting mounting part 630 to limit the rearward rotation angle of the main limiting plate 510. By providing the auxiliary limiting plate 530, the rearward rotation angle of the main limiting plate 510 is prevented from being too large and thus avoiding collision with other components (such as the main mounting bracket 600).

[0093] In some embodiments, see Figure 2The bottom of the main slide 102 is provided with a cascading hole 104, so that components such as wires can pass through the cascading hole 104 to achieve cascading with other lamps. Specifically, the cascading hole 104 is located on the side of the side frame 120 away from the opening side of the main slide 102.

[0094] Based on the same inventive concept, this application also provides a surface-mounted lighting assembly, see reference. Figure 1 and Figure 2 The surface-mounted lighting assembly includes a lighting body 700 and the aforementioned lighting frame. The side edge of the lighting body 700 is slidably inserted into the main groove 102 on the corresponding side of the lighting frame.

[0095] Compared with the prior art, the lamp frame provided in this application has lower assembly difficulty and improved installation efficiency by adopting the above-mentioned surface-mounted lamp assembly, making it more suitable for high-altitude operation scenarios.

[0096] In some embodiments, a lamp magnetic member 800 is provided on the side of the lamp body 700 facing the closed frame 300, and a second frame magnetic member 900 is provided on the side of the closed frame 300 facing the lamp body 700. The second frame magnetic member 900 is located between two sets of first frame magnetic members 400 and can be magnetically connected with the lamp magnetic member 800. The lamp magnetic member 800 and the second frame magnetic member 900 cooperate to add a magnetic connection position in the middle of the closed frame 300, preventing the middle of the closed frame 300 from bending after installation, making the gap between the closed frame 300 and the lamp body 700 more uniform, and ensuring aesthetic appearance. The number of second frame magnetic members 900 can be one, located in the middle of the corresponding side of the lamp body 700, with a corresponding lamp magnetic member 800; or, at least two second frame magnetic members 900 can be provided, evenly distributed along the edge of the corresponding side of the lamp body 700.

[0097] In some specific embodiments, see Figures 11 to 13 The lamp magnetic component 800 includes a second magnetic connecting bracket 810 and a second magnetic component 820. The second magnetic connecting bracket 810 is connected to the lamp body 700, and the second magnetic component 820 is connected to the second magnetic connecting bracket 810 on the side facing the closed frame 300. The second frame magnetic component 900 is fitted and connected to the side of the closed frame 300 facing the main frame 100 (specifically, the connecting frame 110). The second magnetic component 820 is magnetically connected to the second frame magnetic component 900. The second magnetic component 820 is a permanent magnet, and its implementation includes, but is not limited to, neodymium iron boron magnets and iron-cobalt-nickel magnets.

[0098] Optionally, the second magnetic connection bracket 810 is an integrally bent bracket, which has a lamp connecting plate 811 that fits against the rear side of the lamp frame 720, a magnetic connecting plate 812 that connects to the second magnetic component 820, and an elastic bending plate 813 disposed between the lamp connecting plate 811 and the magnetic connecting plate 812. After the second magnetic connection bracket 810 is installed with the lamp body 700, it stands on the rear side of the lamp frame 720 in a rearward extended posture. The setting of the elastic bending plate 813 allows the second magnetic component 820 to be positioned more flexibly in the first direction, so as to achieve spatial adaptation with the second frame magnetic component 900; in addition, it can also generate a certain elastic deformation at the moment of attraction with the second frame magnetic component 900 and at the moment of detachment of the second frame magnetic component 900 from the second magnetic component 820, so as to achieve buffering and avoid the force generated by rigid collision from being transmitted to the lamp body 700, which would cause damage to the lamp body 700.

[0099] Optional, see Figure 2 and Figure 14 The front of the magnetic connecting plate 812 contacts the second magnetic component 820, and the back is provided with a nut seat 8121. A through hole is opened in the middle of the second magnetic component 820, and a fastener passing through the through hole is screwed to the nut seat 8121, thereby fixing the second magnetic component 820. The through hole on the second magnetic component 820 is a countersunk hole, with the end of the fastener recessed into the second magnetic component 820 to prevent the fastener from protruding and affecting the attraction with the second frame magnetic component 900.

[0100] Based on the first frame protrusion, the rear edge and / or front edge of the second frame magnetic member 900 form a limiting flange 910. The limiting flange 910 contacts the rear side and / or front and rear sides of the first frame protrusion to limit the displacement of the second frame magnetic member 900 in the front-back direction, so as to facilitate its alignment with the mounting position on the first frame protrusion.

[0101] In this embodiment, the bonding connection between the second frame magnetic member 900 and the first frame protrusion includes, but is not limited to, connection via threaded connectors, connection via rivets, bonding via adhesive, and snap-fit ​​connection, etc., which will not be listed here. The figure exemplarily shows a scheme in which through holes are provided on the first frame protrusion and the second frame magnetic member 900, and the connection is made via threaded connectors.

[0102] Optionally, the second magnetic component 820 is a permanent magnet (e.g., a neodymium iron boron magnet), and the second frame magnetic component 900 is a ferromagnetic sheet metal component (e.g., an iron sheet, an iron-nickel alloy sheet, etc.). The sheet design can greatly compress the size of the second frame magnetic component 900 in the first direction, making the closed frame 300 fit more closely to the lamp body 700, and making the structure of the lamp frame more compact.

[0103] The installation process of the surface-mounted lighting assembly in this application is as follows:

[0104] 1) Fix the U-shaped main frame 100 to the pre-drilled holes in the ceiling using the main mounting bracket 600;

[0105] 2) With the side of the lamp body 700 with the lamp magnetic 800 facing the operator, lift the lamp body 700, and then push the lamp body 700 into the main frame 100 from the opening side. During this process, the lamp frame 720 on both sides of the lamp body 700 slides in the corresponding main slide groove 102 until the lamp frame 720 on the corresponding side of the lamp body 700 is inserted into the second frame limiting groove 112.

[0106] 3) After the main body 700 of the lamp is fully pushed into the main frame 100, force is applied to the toggle plate 520 to switch the main limiting plate 510 from the horizontal avoidance state to the vertical downward limiting state.

[0107] 4) Align the first frame magnetic 400 on both sides of the closed frame 300 with the main slide grooves 102 on both sides and insert them. The guide groove 401 in the first frame magnetic 400 cooperates with the main guide rail 103 to make the closed frame 300 gradually align. At the same time, under the action of magnetic attraction, the closed frame 300 will automatically fit the main frame 100 until the opening of the main frame 100 is completely closed, and the assembly is complete.

[0108] The surface-mounted lighting assembly of this application features a guide groove 401 on the closed frame 300 that facilitates alignment without interference fit during high-altitude installation, reducing the difficulty of high-altitude operations and making assembly more convenient and efficient. The use of magnetic attachment points on both sides and in the middle of the closed frame 300 minimizes the difference in gap between the closed frame 300 and the lighting body 700 compared to the ends, resulting in higher consistency and improved overall aesthetics. Compared to traditional surface-mounted solutions, the surface-mounted lighting assembly is more compact in the front-to-back direction, allowing the main frame 100 and closed frame 300 to better enclose the lighting body 700, reducing the oppressive feeling of surface-mounted lighting and improving human comfort. Even if the lighting body 700 is vibrated during subsequent maintenance and disassembly after being fully inserted into the main frame 100, it will not slip out, offering higher safety than traditional surface-mounted lighting.

[0109] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
