The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
In an embodiment, as shown in fig. 1 to 6, an LED flat lamp with improved connection strength includes a frame, an LED light strip, and a light guide plate assembly, where the frame includes a plurality of sectional materials 1 connected end to end in sequence, two adjacent sectional materials 1 are inserted into a same corner fitting 2 and fixed to each other, and an end surface of each sectional material 1 is provided with a slot 11, a connecting slot 12, a light strip receiving slot 13, and a clamping slot 14 for receiving an edge of the light guide plate assembly; wherein, one side of the connecting groove 12 in the thickness direction of the frame is provided with an opening;
the corner fitting 2 comprises a body 21, a plug column 22, a connecting plate 23 and a reinforcing rib 24. The body 21 is provided with a mounting hole 211 penetrating in the thickness direction of the frame. The two insertion posts 22 are respectively located on the body 21 and extend into the slots 11 of the corresponding side profiles 1. The two connecting plates 23 are respectively paved on the opening of the connecting groove 12 of the corresponding side section bar, and the connecting plate 23 is also provided with a connecting hole 231 corresponding to the position of the corresponding side connecting groove. The number of the reinforcing ribs 24 is two, each reinforcing rib 24 is fixed on a corresponding connecting plate 23 and is arranged in a connecting groove on the corresponding side, the reinforcing ribs are multiple sections which are distributed at intervals, and mounting channels 241 corresponding to the connecting holes are arranged between the adjacent sections;
the angle piece 2 is connected with the section bar 1 through screws penetrating through the connecting holes 231 and the mounting channels 241, and the screws are clamped between the reinforcing ribs of adjacent sections and between two opposite groove walls of the connecting grooves.
The frame of traditional LED panel light is structure as an organic whole, can not adjust the size of a dimension that the frame encloses. During assembly, the combination direction of the frame and the light guide plate assembly is perpendicular to the surface of the light guide plate. Specifically, the lower part of the frame extends inwards to form a supporting plate. After the light guide plate assembly is arranged in the frame, the edge part of the light guide plate assembly is abutted against the supporting plate. And the light guide plate assembly and the supporting plate are fixed through the screws, and when the fixing is carried out, stress is concentrated at the connecting part of the light guide plate assembly and the screws, so that the edge of the light guide plate assembly is easy to crack due to improper operation, and the assembly is inconvenient.
The frame of the flat lamp in this embodiment adopts a split structure, and during assembly, the combined direction of the frame and the light guide plate assembly is parallel to the plate surface of the light guide plate. Specifically, each profile 1 and each corner fitting 2 are placed at the edge of the light guide plate assembly, the LED strip is placed in the strip channel 13, and the connection between the profile 1 and the corner fitting 2 and the connection between the profile 1 and the light guide plate assembly are maintained but are not locked, for example, the edge of the light guide plate assembly is placed in the clamping groove 14 but does not go deep into the bottom of the clamping groove 14. After the edge frame is approximately aligned with each side of the light guide plate assembly, the distance between the two opposite sectional materials is gradually reduced along the direction parallel to the light guide plate assembly until the edge frame and the light guide plate assembly are mutually locked. Finally, the adjacent section bars 1 and the corner pieces 2 are locked by screws penetrating through the connecting holes 231 and the mounting channels 241, and the product assembly is completed. Because the screw does not contact with the light guide plate assembly when locked, the light guide plate assembly is not broken due to overlarge force application, and the assembly is convenient. After assembly, the edges of the light guide plate assembly are clamped into the clamping grooves 14, so that the light guide plate assembly is uniform in stress and strong in impact resistance.
In addition, the profile 1 in the present embodiment has a certain tolerance capability in a direction parallel to the light guide plate assembly when being mated with the light guide plate assembly. If the size of the opening of the installation site is better than the size of the LED panel lamp, the LED panel lamp can be directly fixed on the wall body of the building through the screws penetrating through the installation holes 211. If the size of the opening on the installation site is different from the size of the frame, the screws can be properly loosened, and the frame can be fixed after being readjusted. The section bar 1 can be made of metal materials, and the installation position of a screw in the connecting groove 12 can be conveniently adjusted. Thereby effectively avoiding the mounting defect or the mounting failure caused by the size problem.
Specifically, when section bar 1 and corner fittings 2 dock, in the slot 11 on inserting post 22 on corner fittings 2 inserted section bar 1, restriction section bar 1 relative corner fittings 2 along the direction of keeping away from the light guide plate subassembly and move, simultaneously in stiffening rib 24 on corner fittings 2 inserted the spread groove 12 on section bar 1, at this moment section bar 1 is not dead between the relative corner fittings 2, and section bar 1 can be followed and taken out in corner fittings 2, and then the adjustment frame size. The profile 1 can be locked to the corner fitting 2 by means of screws which pass through the connecting bores 231.
If the connection holes 231 are provided in the connection plate 23 at a position not adjacent to the reinforcing ribs 24, the looseness between the profile 1 and the corner fitting 2 may still occur after several alternating stresses have been applied after the product has been assembled. Analysis shows that the relative displacement between the profile 1 and the corner fitting 2 generates a shearing force applied to the screw, and the shearing force applied to the screw by the profile 1 and the shearing force applied to the screw by the corner fitting 2 are mutually staggered in the thickness direction of the frame to generate a torque to the screw, and the torque causes the inclination of the screw, breaks an internal thread generated when the screw is installed, and finally causes loosening.
In the embodiment, the connecting hole 231 is formed at a position adjacent to the reinforcing rib 24, and the reinforcing rib 24 is inserted into the connecting groove 12, so that the mounting channel 241 and the connecting groove 12 are greatly overlapped in the thickness direction of the frame, the torque on the screw is reduced under the same external force, the screw is not easy to incline, the screw is effectively prevented from loosening, and the connecting strength between the sectional material 1 and the corner piece 2 is further improved.

The mounting portion 17 extends from the corner portion toward the inside of the bezel, and a lamp band groove 13 and a holding groove 14, which communicate with each other and open toward the inside of the bezel, are provided in the mounting portion.
The connecting groove 12 is formed by the circumvallation of the corner 15, namely the connecting groove 12 is opened outwards, the connecting groove 12 is integrally positioned in the corner 15, the size of the section bar 1 in the thickness direction of the frame is reduced, and the structure of the section bar 1 is more compact. Further, forming the coupling grooves 12 by invagination is more resistant to the impact of an external force parallel to the light guide plate assembly than forming the coupling grooves by epitaxy, and the structural strength is higher.
The installation part 17 is directly connected on the corner part 15, no other connection structure is arranged in the middle, the bottom of the lamp groove 13 is directly connected with the corner part 15, when the section bar 1 bends relative to the light guide plate component, torsion directly acts on the corner part 15, the included angle of the installation part 17 relative to the corner part 15 is kept relatively fixed, and the rigidity of the section bar 1 is improved.
