DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0030] The embodiment of the present application discloses a profile for splicing straight light-emitting panel lamp frame.

[0031] Referring to Figures 1 to 5A profile for splicing the frame of a direct-emitting panel light includes a side plate 61 and a clip 62. Specifically, the side plate 61 is generally rectangular and vertically arranged, with the side with the larger cross-sectional area being horizontally arranged. The side plate 61 serves as the base of the frame 1 of the profile 6. The clip 62 is a long strip and is located on the inner side of the side with the larger cross-sectional area of ​​the side plate 61. The clip 62 is integrally set on the lower side of the side plate 61 so that the clip 62 and the lower side of the side plate 61 appear to form an L-shape. The clip 62 is used to snap into the side of the diffuser plate 2, thereby installing the diffuser plate 2. With this design, the light-emitting surface of the diffuser plate 2 is not blocked by the clip 62, thereby increasing the light-emitting area of ​​the diffuser plate 2 and improving the overall luminous efficiency of the direct-emitting panel light.

[0032] A light guide plate 63 is provided on the side plate 61. The light guide plate 63 is also rectangular and is located on the same side as the locking block 62. The light guide plate 63 is inclined on the side plate 61, and the lower side of the support plate is connected to the lower side of the side plate 61. The connection between the light guide plate 63 and the side plate 61 is at a distance from the locking block 62. The upper side of the light guide plate 63 extends away from the side plate 61, so that the light guide plate 63 and the side plate 61 form a predetermined angle. On the upper side of the light guide plate 63, the back plate 3 of the panel light is detachably connected to the light guide plate 63 by means of snap-fit ​​or other means. So after the frame 1 is assembled by the profile 6, the back plate 3 is connected to the light guide plate 63. At this time, the cross-sectional area of ​​the space enclosed by multiple light guide slopes gradually increases in the direction away from the back plate 3. When the light strip 4 emits light on the back plate 3, the light guide plate 63 can diffuse the light source of the light strip 4, improve the uniformity of light output and reduce the dark area caused by the frame blockage, and enhance the luminous effect of the panel light.

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

[0034] To improve the lifespan of the panel light, a reinforcing strip 64 is provided between the side plate 61 and the light guide plate 63. The reinforcing strip 64 increases the overall deformation resistance of the profile 6, preventing the overall frame of the panel light from deforming under stress, thereby improving the lifespan of the panel light.

[0035] In the embodiment of the present application, the detachable connection between the back plate 3 and the light guide inclined plate 63 is realized by screws. Since the screw holes on the back plate 3 are pre-drilled during the production of the back plate 3, the assembly of the panel lamp is facilitated. Therefore, the positioning groove 65 is arranged on the side of the light guide inclined plate 63 away from the side plate 61. The positioning groove 65 is in the form of a through groove, the groove opening of the positioning groove 65 is arranged upward, and the length direction of the positioning groove 65 is parallel to the length direction of the clamping block 62. When the back plate 3 is installed on the frame 1, the reserved screw holes on the back plate 3 are aligned with the positioning groove 65, so as to improve the installation accuracy of the back plate 3 as much as possible, avoid secondary installation, and improve the installation efficiency of the panel lamp.

In the embodiment, the diffusion plate 2 is in the form of a rectangular plate. Diffusion grooves 21 are arranged on the four peripheral sides of the diffusion plate 2. The diffusion grooves 21 are arranged around the diffusion plate 2. The diffusion grooves 21 are used for inserting the clamping blocks 62. The thickness of the diffusion plate 2 is 4 mm, so as to ensure that the light of the panel lamp has better uniformity. The back plate 3 is designed in the form of a flat plate, that is, the back plate 3 is in the form of a thin plate. In the embodiment, the back plate 3 is in the form of a rectangular plate. The back plate 3 is made of an aluminum plate or an iron plate 5 with a thickness of 0.3 mm-1 mm. The surface of the back plate 3 is treated with white baking paint. Since the back plate 3 is detachably connected by screws, screw holes are pre-drilled at predetermined positions on the back plate 3 during the processing of the back plate 3. Therefore, during installation, the screw holes on the back plate 3 are aligned with the positioning grooves 65 on the light guide inclined plate 63, so as to realize accurate installation. The lamp strip 4 is arranged on the side of the back plate 3 close to the diffusion plate 2. A plurality of lamp strips 4 are arranged and uniformly spaced. The lamp strip 4 diffuses light on the diffusion plate 2.

[0037] In one embodiment, the frame 1 comprises a plurality of section bars 6. The section bars 6 are connected end to end to form a closed shape. In the four-sided frame 1, after the section bars 6 are extruded into long strips with a predetermined length according to the cross section, the two sides of the section bars 6 are cut at an angle of 45° according to the actual situation. Then, the four section bars 6 are spliced end to end to form a rectangle. Then, the back plate 3 is installed on the light guide inclined plates 63 of the four section bars 6 by screws, so as to realize the splicing of the section bars 6. The panel lamp in the embodiment is suitable for wider lamps.

[0038] In another embodiment, the frame 1 comprises the section bars 6 and the iron plates 5, wherein two section bars 6 are arranged closely, two iron plates 5 are arranged on the two sides of the two section bars 6 respectively, the iron plates 5 and the section bars 6 are connected head to tail to form a closed shape, and the iron plates 5 are connected with the reinforcing bars 64 of the section bars 6 by screws, and the iron plates 5 are provided with screw mounting holes in the production process. The panel light in this embodiment is suitable for longer lamps;

[0039] In order to facilitate the installation of the iron plates 5, the reinforcing bars 64 are provided with positioning through grooves 641, the grooves of the positioning through grooves 641 are arranged upward, the openings of the two sides of the positioning through grooves 641 are arranged horizontally, the width of the positioning through grooves 641 is smaller than the diameter of the screws, the screws are expansion screws, when the iron plates 5 are connected with the section bars 6, the holes on the iron plates 5 are aligned with the openings of the positioning through grooves 641, the screws are clamped in the positioning through grooves 641 to realize fastening, the connection between the iron plates 5 and the section bars 6 is completed, which is accurate and convenient, and in other embodiments, the positioning through grooves 641 can also be used to accommodate screws, power supplies and the like, which is convenient for later maintenance or replacement and convenient for storage.
