From the viewpoint of processing and heat dissipation, the backplate 20 is stamped from a metal sheet (e.g., ST 13) to form a raised housing-like structure, which includes a central region 22 and an edge region 23 disposed at the periphery of the central region 22, the central region 22 of the backplate 20 is raised to form a cavity for accommodating the light emitting element 40, the cavity includes a flat bottom wall and inclined side walls, the light emitting element 40 is fixed on the bottom wall, and the diffuser plate 30 is disposed opposite to the backplate 20 to close the cavity. The light emitting assembly 40 is composed of a plurality of light bars 41, each light bar 41 includes a substrate 42 and a plurality of LED beads 43 mounted on the substrate 42, and the LED beads 43 are distributed in a matrix form inside the back plate 20, so that the light sources are uniformly distributed. The light bar 41 further comprises a lens covered on the LED lamp beads 43, the diffusion plate 30 has a light transmission function, light emitted by the LED lamp beads 43 sequentially passes through the lens and the diffusion plate 30, and a plurality of LED point light sources form an even area light source after the light is diffused.

The substrate 42 comprises a metal layer, an insulating layer and a circuit layer, and the LED lamp beads 43 are welded on the circuit layer. The substrate 42 may alternatively be an FR-4 glass fiber board, which has no metal layer. In some embodiments, the surface of substrate 42 is coated with a solder resist ink layer that is white to improve light reflection efficiency.

When the frame 10 is mounted, the stopper surface 13 of the corner connector 12 abuts against the end of the side frame strip 11, and is stopped by the anti-slip block 15 abutting against the outer periphery of the side frame strip 11, and then fixed by screws. Compare in prior art directly use frame strip 11 and corner connector 12 through inserting and use the mode of fix with screw, frame 10 after this application panel light 100 assembles is more firm, has anti-drop's effect.

In an embodiment, the side frame strip 11 is a profile, and has a cavity 111 extending along a length direction thereof, the limiting surface 13 is provided with a plurality of positioning posts 131 inserted into the cavity 111, and the plurality of positioning posts 131 are attached to different side surfaces of the cavity 111. As shown in fig. 5 to 7, the number of the cavities 111 is 2, the sizes of the cavities are different, and of course, the specific size of the cavity 111 and the specific shape of the cross section can be set according to actual requirements, and in this embodiment, in consideration of the production process, the cross section of the cavity is rectangular.

In an embodiment, the position-limiting surface 13 is provided with fixing posts 132 corresponding to one of the positioning posts 131, and the fixing posts 132 are provided with screws (not shown in the drawings, and the screw holes 17 in fig. 6 are used for mounting the screws) penetrating through the side wall of the cavity 111 and connecting with the corresponding positioning posts 131. In order to increase the overall structural strength, the side of the fixing column 132 facing the cavity 111 has a protruding pad 133 abutting against the side frame strip 11.

As shown in fig. 5 and 7, the side frame strip 11 is provided with a first mounting surface 112 and a second mounting surface 113 (the height is the height along the vertical direction when the panel lamp 100 is in the mounted state), the edge of the diffuser plate 30 is overlapped on the first mounting surface 112, the edge (i.e., the edge area 23) of the back plate 20 is fixedly connected to the second mounting surface 113 through a fastening screw, and has an annular rib 21 formed by bending itself, the annular rib 21 abuts against the diffuser plate 30 to abut against the first mounting surface 112, the first mounting surface 112 has a rib 114 extending along the length direction of the side frame strip 11, and the rib 114 is located outside the position where the back plate 20 abuts against the diffuser plate 30.

Because the back plate 20 has a certain elasticity, when the annular rib 21 abuts against the diffusion plate 30, the annular rib 21 is elastically deformed, so that the annular rib 21 applies pressure to the diffusion plate 30, at this time, the rib 114 is equivalent to a fulcrum, and the diffusion plate 30 has an upward force through the rib 114, thereby preventing the central portion (the geometric center of the diffusion plate 30 or the geometric center close to the diffusion plate 30) of the diffusion plate 30 from collapsing downward.

In one embodiment, to facilitate the fixed mounting of the back panel 20 to the bezel 10, the corner connectors 12 have a limit step surface 16 flush with the second mounting surface 113.

For ease of installation, the edge of the extension 14 is provided with a chamfer 141. Specifically, when the corner connecting member 12 is inserted into the side frame strip 11, the positioning column 131 is inserted into the cavity 111, and the side frame strip 11 is inserted into the inner surface of the extending portion 14 to abut against the anti-falling block 15, so that the installation needs to be performed while considering both, which is more troublesome, and after the chamfer 141 is provided, the chamfer 141 can abut against the inner surface of the extending portion 14, which is guided into the side frame strip 11, against the anti-falling block 15, thereby facilitating the installation. In this embodiment, each anti-slip block 15 can be abutted against the two frame strips 11. Wherein, the included angle of the two frame strips 11 connected with the anti-drop block 15 is 90 degrees.

In one embodiment, the anti-slip block 15 abuts against the light emitting side of the diffuser plate 30, increasing the friction of the diffuser plate 30.
