[0025] Specifically, the outer shell 1 protects the LED lamp and other structures inside the lighting device, and the motor 2 is fixed to the outside of the outer shell 1, so that the motor 2 remains stable during operation without shaking, thereby driving the threaded rod 6 to rotate during operation. Slide grooves 5 are provided on the front and rear sides of the lower surface of the outer shell 1, so that when the threaded rod 6 rotates, the threaded block 7 connected to its outside can move along the slide groove 5, and can drive the cleaning rod 10 to move while moving. The cleaning rod 10 will drive the slider 9 to move in another slide groove 5, and the guiding role played by the guide rod 8 makes the cleaning rod 10 move horizontally under the cooperation of the slider 9 and the threaded block 7, wherein the cleaning rod 10 is fixedly connected to a plurality of springs 11 inside, which can push the brush 12 to be close to the light-transmitting plate 3, and brush off the dust on the surface of the light-transmitting plate 3 when moving, thereby ensuring the LED lighting effect and improving the user experience. At the same time, there is no need to climb high for manual cleaning, which reduces certain safety hazards.

[0026] Reference Figure 3 and Figure 5 The clamping assembly includes four limit grooves 13, and the four limit grooves 13 are all opened inside the shell 1. The inside of the limit groove 13 is fixedly connected with a spring 2 14, and the other end of the spring 2 14 is fixedly connected with a movable block 15, one side of the movable block 15 is fixedly connected with a pull rod 16, and the other side of the movable block 15 is fixedly connected with a clamping block 17. Two clamping grooves 18 are opened on the left and right sides of the light-transmitting plate 3, the outside of the movable block 15 is slidably connected to the inside of the limit groove 13, the spring 2 14 is sleeved on the outside of the pull rod 16, one end of the pull rod 16 passes through the outer wall of the light-transmitting plate 3, one end of the two pull rods 16 on the adjacent side is fixedly connected with a moving rod 19, and the outside of the clamping block 17 is slidably connected to the inside of the clamping groove 18.

[0027] Specifically, four limit grooves 13 are provided inside the shell 1, two on each side of the left and right sides of the shell 1. The moving rod 19 can pull the two pull rods 16 on the same side to move, and then the movable block 15 is driven to slide in the limit groove 13 under the action of the pull rod 16, and the spring 2 14 is compressed. At the same time, the limit groove 13 can limit the movement of the movable block 15 and the spring 2 14, so that the structure remains stable during operation and will not fail. Then, the movable block 15 drives the card block 17 to disengage from the card groove 18, so that the light-transmitting plate 3 can be removed, so that the user can inspect the lighting device without the aid of tools, thereby extending the service life of the device. When installing the light-transmitting plate 3, after loosening the moving rod 19, the spring 2 14 will lose pressure and release elastic potential energy, and then push the card block 17 to engage with the card groove 18, thereby realizing the installation and fixation of the light-transmitting plate 3.

[0028] Reference Figure 1A controller 4 is installed at the middle position of the top of the shell 1, and suspension rods 20 are fixedly connected to the left and right sides of the top of the shell 1. Cooling fans 21 are installed on the left and right sides of the top of the shell 1.

[0029] Specifically, the operation of the LED lighting device can be controlled by the controller 4, and a power cord is provided on the top of the controller 4 to connect to an external power supply to ensure the normal use of the device. The lighting device is installed on the top of the classroom through the suspension rod 20 to provide a good lighting effect. The lighting device can be cooled by the cooling fan 21 to ensure the normal operation of the LED lighting device and reduce power consumption.

[0030] Working principle: When using this lighting device, the device can be fixed on the top of the classroom through the hanging rod 20. When the light-transmitting plate 3 needs to be cleaned, the motor 2 can be started, and the threaded rod 6 can be driven by the motor 2 to rotate, so that the threaded block 7 connected to the outside of the threaded rod 6 moves along one of the slide grooves 5, and at the same time, the slider 9 is driven by the cleaning rod 10 in the other slide groove 5, and slides along the guide rod 8. With the cooperation of the two, the cleaning rod 10 is adapted to the light-transmitting plate 3 and moves horizontally. Then, under the push of multiple springs 11 inside the cleaning rod 10, the brush 12 is adapted to the light-transmitting plate 3, and the dust on the surface of the light-transmitting plate 3 is brushed off while moving, so that the surface of the light-transmitting plate 3 is clean and dust-free, thereby improving the lighting effect of the LED lamp and reducing the risk of manual climbing for cleaning.

[0031] If the device needs to be repaired, the moving rods 19 on both sides of the shell 1 can be pulled, and the two pull rods 16 can be moved by the moving rods 19, and then the pull rods 16 drive the movable block 15 to move, and at the same time, the spring 2 14 will be compressed, and the movable block 15 will drive the card block 17 to move. After disengaging from the card slot 18, the light-transmitting plate 3 can be removed from the shell 1, thereby completing the disassembly operation, which is convenient for users to repair the lighting device without the aid of tools, thereby extending the service life of the device.
