[0002] LED flat panel light is a kind of lamp, which has the characteristics of energy saving, high brightness, no mercury, no infrared, no ultraviolet, no electromagnetic interference, no thermal effect, no radiation, and no flicker. The lamp is light in weight and has multiple ways such as embedded and hanging wire.

[0003] Among them, the LED flat panel light includes a light board and lamp beads installed on the light board. During the installation of the LED light board, screws are usually used to directly tighten the light board into the lampshade for fixed installation, and then the whole is fixedly installed on the ceiling of the room.

It is laterally movably plugged into the fixed block 701, and a limiting hole 702 is provided on one side of the connecting plate 5 for clamping with one side of the limiting pin 7, and a handle 703 is fixedly connected to the other side of the limiting pin 7, and the inner side of the handle 703 is connected to the fixed block 701 through a contracted spring 704, and the outer side of the plug-in port 9 is rotatably connected with a rotating sleeve 1001 threadedly sleeved on the outer side of the threaded pin 10, a limiting block is fixedly provided on the inner wall of the plug-in port 9, and a limiting groove 1002 clamped on the limiting block is laterally provided on the outer side of the threaded pin 10, a sealing cover 1003 is sleeved on the outer side of the threaded pin 10 and the rotating sleeve 1001, and the sealing cover 1003 is magnetically adsorbed on the outer side of the lamp holder shell 1.

[0024] Based on the above structure, when the LED lamp board body 2 is subsequently inspected and maintained, the staff will pre-thread the lampshade 4 and remove it from the opening 3 at the bottom of the lamp holder shell 1, and then the staff will remove the sealing cover 1003 and rotate the adjusting rotating sleeve 1001. The rotating sleeve 1001 will threadably drive the threaded pin 10. Since the limiting groove 1002 on the outside of the threaded pin 10 is engaged with the limiting block on the inner wall of the plug interface 9, the threaded pin 10 will move laterally and drive the blocking block 11 at the inner end to disengage from the groove 8 on the outside of the lamp board body 2.
