Description

Technical Field

[0001] The present invention relates to the technical field of LED lighting, and in particular to a profile for splicing frames of a direct-light panel lamp and a panel lamp. Background Art

[0002] Direct-emitting panel lights are widely used in commercial and home environments, offering advantages such as uniform illumination and soft light. However, conventional panel lights utilize a concave, box-shaped backplane, requiring a separate mold. This is expensive and complex to produce. Furthermore, to prevent the diffuser from falling out, the frame often compresses a large area around the diffuser, obscuring the actual luminous area and affecting luminous efficiency.

[0003] Furthermore, some existing solutions require additional support structures when splicing or widening the frame, which limits size customization and production flexibility. Therefore, it is necessary to provide a frame profile that can be quickly spliced ​​and reduces backplane customization to solve the above problems. Summary of the Invention

[0004] In order to remedy the deficiencies of the prior art, the present application proposes a profile for splicing the frames of direct-light panel lights and a panel light.

[0005] First, a profile for splicing the frame of a direct-emitting panel light adopts the following technical solution:

[0006] A profile for splicing a straight-light panel lamp frame comprises a side plate and a clamping block. The clamping block is arranged on the lower side of the clamping block and is used to be clamped into the side of a diffusion plate.

[0007] Preferably, a light guide inclined plate is provided on the side panel, and the light guide inclined plate is provided on the same side as the blocking block, and the light guide inclined plate is obliquely provided on the side panel, the lower side of the light guide inclined plate is connected to the lower side of the side panel, and the upper side extends toward the side away from the side panel, and the side of the light guide inclined plate away from the side panel is used for detachable connection with the back panel.

[0008] Preferably, the upper side of the light guide inclined plate does not exceed the upper side of the side plate.

[0009] Preferably, a reinforcement bar is connected between the side plate and the light guide inclined plate, and the reinforcement bar is respectively connected to a side surface of the side plate and the light guide inclined plate that is close to each other.

[0010] Preferably, a positioning groove is provided on the upper side of the light guide inclined plate, and the positioning groove is used for positioning the back plate during installation.

[0011] Preferably, a positioning through groove is provided on the reinforcing strip, and the side opening of the positioning channel is used for the installation and positioning of the iron plate.

[0012] Secondly, a panel light adopts the following technical solutions:

[0013] A panel light comprises a frame, a diffusion plate, a back plate and a light bar. The frame comprises a plurality of profiles. The side of the diffusion plate is provided with a diffusion groove for inserting the card block on the side plate. The back plate is mounted on the frame.

[0014] Preferably, the frame includes a plurality of the profiles, and the plurality of profiles are connected end to end to form the frame.

[0015] Preferably, the frame includes multiple profiles and iron plates, two frames are provided, and the two frames are closely spaced apart, and two iron plates are also provided, and the two iron plates are detachably connected to the same side of the two profiles to connect the same side of the two profiles.

[0016] Preferably, the thickness of the diffuser plate is 4 mm.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. When the diffuser panel is installed on the frame, the block on the side panel will be inserted into the diffusion groove on the side of the diffuser panel. The side wall of the diffusion groove cooperates with the block to achieve stable installation of the diffuser panel. At the same time, because the block is inserted into the side of the diffuser panel, it does not restrict the surface of the diffuser panel. The cooperation between the block and the diffusion groove maximizes the utilization of the extra light-emitting area of ​​the diffuser panel, increases the light-emitting area of ​​the diffuser panel, and improves the overall luminous efficiency of the direct-emitting panel light.

[0019] 2. In this solution, the frame is made of profiles. Since the profiles are processed by extruding long strips according to the cross-sectional diagram and then cutting them into specified sizes and shapes according to actual needs, the length of the profiles can be produced according to the required size of the panel light. There is no need for additional equipment, only the cut length of the profile needs to be changed. This allows for flexible customization of product sizes, a simple production process, and can significantly reduce mold costs and processing difficulty, resulting in low costs.

[0020] 3. The tilted light guide plate can improve the uniformity of light output and reduce dark areas caused by frame obstruction;

[0021] 4. The reinforcement strip not only provides structural stability but can also be used to store screws, power supplies, etc., making it easier to maintain or replace them later. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The embodiment of the present application discloses a profile for splicing frames of direct-light panel lights.

[0031] Reference Figures 1 to 5, a profile for splicing the frame of a direct-light panel lamp includes a side panel 61 and a clamping block 62. Specifically, the side panel 61 is in the shape of a rectangular plate as a whole. The side panel 61 is arranged vertically as a whole, and the side surface of the side panel 61 with a larger cross-sectional area is arranged horizontally. The side panel 61 is used as the basis of the profile 6 frame 1, and the clamping block 62 is in the shape of a long strip. The clamping block 62 is arranged on the inner side surface of the side panel 61 with a larger cross-sectional area, and the clamping block 62 is integrally arranged on the lower side of the side panel 61 so that the clamping block 62 and the lower side panel 61 appear to be L-shaped as a whole. The clamping block 62 is used to clamp into the side edge of the diffuser plate 2, and the diffuser plate 2 is installed by the clamping plate. In this design method, the luminous surface of the diffuser plate 2 will not be blocked by the clamping block 62, thereby increasing the luminous area of ​​the diffuser plate 2 and improving the overall luminous efficiency of the direct-light panel lamp.

[0032] A light guide inclined plate 63 is provided on the side plate 61. The light guide inclined plate 63 is also in the shape of a rectangular plate. The light guide inclined plate 63 and the card block 62 are provided on the same side. The light guide inclined plate 63 is tilted as a whole on the side plate 61, and the lower side of the support plate is connected to the lower side of the side plate 61. There is a distance between the connection between the light guide inclined plate 63 and the side plate 61 and the card block 62. The upper side of the light guide inclined plate 63 extends in a direction away from the side plate 61 so that the light guide inclined plate 63 and the side plate 61 form a predetermined angle. On the upper side of the light bevel plate 63, the back panel 3 of the panel light is detachably connected to the light guide bevel plate 63 by means of snap-fitting or the like. Therefore, after the frame 1 is assembled through the profile 6, the back panel 3 is connected to the light guide bevel plate 63. At this time, the cross-sectional area of ​​the space enclosed by the multiple light guide bevels gradually increases in the direction away from the back panel 3. When the light strip 4 emits light on the back panel 3, the light guide bevel plate 63 can diffuse the light source of the light strip 4, thereby improving the uniformity of light output and reducing the dark area caused by the frame obstruction, thereby enhancing the luminous effect of the panel light.

[0033] In this embodiment, the upper side of the light guide inclined plate 63 does not extend beyond the side plate 61 , so that the back plate 3 is retracted into the overall frame when mounted on the profile 6 , thereby reducing the overall thickness of the panel light.

[0034] In order to increase the service life of the panel light, a reinforcement strip 64 is provided between the side plate 61 and the light guide inclined plate 63. The reinforcement strip 64 increases the overall deformation resistance of the profile 6, avoids the overall frame of the panel light from being deformed by stress, and thus increases the service life of the panel light.

[0035] In the embodiment of the present application, the detachable connection between the back panel 3 and the light guide bevel 63 is achieved by screws. Since the screw holes on the back panel 3 are pre-drilled during the production process of the back panel 3, in order to facilitate the assembly of the panel light, a positioning groove 65 is provided on the side of the light guide bevel 63 away from the connection with the side panel 61. The positioning groove 65 is in the form of a through groove, the notch of the positioning groove 65 is set upward, and the length direction of the positioning groove 65 is parallel to the length direction of the block 62. When the back panel 3 is installed on the frame 1, the screw holes reserved on the back panel 3 can be aligned with the positioning groove 65 to maximize the installation accuracy of the back panel 3, avoid secondary installation, and improve the installation efficiency of the panel light.

[0036] This application also discloses a panel light, referring to Figures 1 to 5 The panel light includes a frame 1, a diffuser 2, a back panel 3 and a light bar 4. Specifically, the frame 1 is composed of multiple profiles 6. The diffuser 2 is made of milky white diffused PMMA. In this embodiment, the diffuser 2 is a rectangular plate. Diffusion grooves 21 are provided on the sides of the diffuser 2. The diffusion grooves 21 are distributed around the diffuser 2. The diffusion grooves 21 are used for inserting the card blocks 62. The thickness of the diffuser 2 is 4 mm to ensure that the light of the panel light has better uniformity. The back panel 3 adopts a flat plate design, that is, the back panel 3 is in the shape of a thin plate. In this embodiment, the back panel 3 It is a rectangular plate, and the back panel 3 adopts 0.3mm-1mm aluminum plate or iron plate 5, and the surface of the back panel 3 is treated with white paint. Since the back panel 3 is detachably connected by screws, screw holes are pre-drilled at predetermined positions on the back panel 3 during the processing of the back panel 3. Therefore, when installing, it is only necessary to align the screw holes on the back panel 3 with the positioning grooves 65 on the light guide inclined plate 63 to complete accurate installation. The light strip 4 is set on one side of the back panel 3 close to the diffuser plate 2. There are multiple light strips 4, and they are evenly spaced. The light strip 4 hits the diffuser plate 2 for diffusion.

[0037] In one embodiment, the frame 1 includes a plurality of profiles 6, which are connected end to end to form a closed shape. In the square frame 1, after the profile 6 is extruded into a strip of predetermined length according to the cross section, the two sides of the profile 6 are cut into 45° according to the actual situation, and then the four profiles 6 are spliced ​​end to end to form a rectangle. The back panel 3 is then mounted on the light guide inclined plates 63 of the four profiles 6 by screws to realize the assembly of the profiles 6. The panel light in this embodiment is suitable for wider lamps.

[0038] In another embodiment, the frame 1 includes a profile 6 and an iron plate 5, wherein two profiles 6 are provided, and two iron plates 5 are also provided. The two profiles 6 are arranged closely, and the two iron plates 5 are respectively arranged on both sides of the two profiles 6. The iron plates 5 and the profiles 6 are respectively connected end to end to form a closed shape, and the iron plates 5 are also connected to the reinforcement strips 64 of the profiles 6 by screws. The iron plates 5 are reserved with holes for screw installation during the production process. The panel light in this embodiment is suitable for longer lamps;

[0039] In order to facilitate the installation of the iron plate 5, a positioning slot 641 is provided on the reinforcing bar 64. The slots of the positioning slot 641 are distributed upward, and the openings on both sides of the positioning slot 641 are arranged horizontally. The width of the positioning channel will be smaller than the diameter of the screw, and the screw is an expansion screw. When the iron plate 5 is connected to the profile 6, the hole on the iron plate 5 is aligned with the opening of the positioning slot 641, and the screw will be stuck in the positioning slot 641 to achieve fastening, thereby completing the connection between the iron plate 5 and the profile 6, which is accurate and convenient. In other embodiments, the positioning slot 641 can also be used to accommodate screws, power supplies, etc., which is convenient for later maintenance or replacement and easy to store.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
