The staff starts the electric push rod, so that its output end drives the movable plate and the rotating column to move along the direction of the telescopic rod, and the push plate moves to the corresponding connecting plate position. Then the staff starts the first motor, and its output shaft drives the second bevel gear to rotate. Under the meshing action of the second bevel gear and the first bevel gear, the rotating column drives the push plate to rotate, so that the push plate can push the corresponding connecting plate, so that the sliding column drives the power supply board and the LED light strip to move along the direction of the annular groove, so as to facilitate the staff to adjust the illumination range of the LED light strip on the lower surface of each power supply board, which can meet the flexible and changeable lighting needs, avoid excessive lighting in some areas and insufficient lighting in other areas, thereby improving the visual effect and comfort.

[0032] 2. After adjusting the illumination range of the LED light strip, the staff controls the rotation of the rotating column to rotate the push plate to the top of the gap between each connecting plate. Then the staff controls the output end of the electric push rod to reset, so that the top plate rises and presses the support frame, thereby limiting the support frame and preventing the LED light strip from being offset due to external force during lighting work.

[0033] 3. The staff controls the electric push rod to reset. When the fifth gear is about to move to the sixth gear position, the staff controls the rotating column and the fourth pulley to rotate. Under the transmission action of the second transmission belt, the third pulley drives the limit rod to rotate, so that the fifth gear rotates to avoid the meshing teeth of the fifth gear colliding with the sixth gear when the fifth gear moves.

Under the action of the connecting shaft, the rotating column rotates relative to the top plate. Under the meshing action of the fifth gear and the sixth gear, the positioning rod drives the second pulley to rotate. Under the transmission action of the first transmission belt, the first pulley drives the round rod to rotate. When the fourth gear meshes with the inner gear ring, the gear is engaged. Under the action, the supporting ring drives the outer gear ring to rotate to prevent the meshing teeth of the second gear from colliding with the outer gear ring when it moves. Then the staff starts the second motor to make its output shaft drive the screw to rotate. The rotating screw drives the lifting plate and the second gear to move along the direction of the slide rod, so that the second gear meshes with the outer gear ring while meshing with the third gear. Then the staff controls the first motor to make the outer gear ring rotate. Under the meshing action of the third bevel gear and the fourth bevel gear, the mounting shaft rotates. Under the meshing action of the first gear and the arc-shaped toothed plate, the rotating shaft drives the rotating frame to rotate, so that the LED light strip can rotate with the corresponding rotating shaft as the reference, thereby further expanding the illumination range of the LED light strip, making the lighting area more extensive and flexible.
