As an optional implementation manner of the embodiment of the application, when the detection signal of the magneto-dependent sensor is received, the motor component is controlled to drive the focusing amplifying component to run to the target position so as to complete pre-reset.

Where Fa denotes a focus lens pre-reset position, za denotes an amplifying lens pre-reset position. The two positions Fa and Za can be set at will according to the debugging effect of the lamp through the man-machine interface of the lamp main control board, and the method is not limited.
As an optional implementation manner of the embodiment of the application, when receiving the instruction of completing the scanning reset operation of the XY axes of the head shaking lamp sent by the scanning plate of the head shaking lamp, the motor assembly is controlled to drive the focusing amplifying assembly to move to the position where the magneto-sensitive sensor is located according to a preset speed until the received detection signal of the magneto-sensitive sensor jumps. Specifically, after the scanning reset operation is finished, the head shaking lamp scanning plate sends an instruction to the focusing amplification control plate, after the focusing amplification control plate receives the instruction, the head shaking lamp scanning plate informs the focusing amplification control plate that the XY axis of the head shaking lamp is ready to be finished, and the XY axis of the head shaking lamp is kept motionless until the focusing is finished; after focusing is finished, the focusing amplification control board is started to reset again, the motor assembly is controlled to move respectively, meanwhile, the motor assembly drives the focusing amplification assembly to run to the position where the magnetic sensor is located according to the preset speed, and when the focusing amplification control board receives the detected magnetic signal to jump in the running process, the running is stopped, and positioning is completed. The magnetic sensitive signal generation jump can be changed from a high frequency signal to a low frequency signal or from a low frequency signal to a high frequency signal, and the magnetic sensitive signal change is not limited herein, so long as the jump occurs.
In one embodiment, as shown in fig. 3A and 3B, after the completion of the scanning reset of the XY axis of the head-shaking lamp, the focus lens F and the magnifying lens Z are respectively moved to a certain position Xa (B) and Ya (a) in the stroke, and then the scanning plate of the head-shaking lamp sends a packet of command to the focus magnification control board, and informs the focus magnification control board that the XY axis of the head-shaking lamp is ready to be completed, and then remains stationary waiting for the completion of focusing. And after focusing is finished, resetting is started again, then the focusing driving motor T1 and the amplifying driving motor T2 respectively drive the focusing lens F and the amplifying lens Z to move towards the positions of the first magnetic sensor Mf and the second magnetic sensor Mz, and in the operation process, when the detected magnetic signals jump, the operation is stopped, so that the positioning is finished. B represents the waiting position of the X axis, a represents the waiting position of the Y axis, and the two positions can be set at will according to the debugging effect of the lamp through the man-machine interface of the lamp main control board, and are not limited herein; ya (a) indicates that the magnetic-sensing signal is optimal for positioning the focusing and amplifying assembly of the computer tilting lamp when the focusing and amplifying assembly is reset and detected at the vertical position of the Y-axis Ya, and Xa (b) is determined according to Ya (a).
As an optional implementation manner of the embodiment of the present application, the controlling the motor assembly drives the focusing and amplifying assembly to move to the position where the magnetic sensor is located according to a preset speed until the received detection signal of the magnetic sensor jumps, may further control the motor assembly to drive the focusing and amplifying assembly to move to a preset zero position along the preset travel direction, and send a focusing and amplifying assembly reset completion instruction to a main control board and a scan board of the head tilting lamp. Specifically, after positioning is completed, the focusing amplification control board drives the motor assembly again to drive the focusing amplification assembly to operate to a preset zero position according to a preset speed, and then a reset completion command is sent to the head shaking lamp main control board and the scanning board. The preset zero position is any position, can be determined according to the optical effect of the focusing and amplifying lens, and is the best position when the gravity center of the oscillating lamp is balanced.
In an embodiment, as shown in fig. 4, the focusing and amplifying control board controls the focusing driving motor T1 and the amplifying driving motor T2 to drive the focusing lens F and the amplifying lens Z to operate to the preset zero positions Fb and Zb, and then sends a reset completion command to the head shaking lamp main control board and the scanning board. Wherein Fb denotes a zero point position after completion of the reset of the focus lens F, and Zb denotes a zero point position after completion of the reset of the focus lens Z.
As an optional implementation manner of the embodiment of the application, consistency of imaging definition among lamps can be improved by ensuring consistency of magnetic sensitivity level detection distances in a resetting process after the resetting is completed. Specifically, because the single desk lamp has different swinging directions of the lamp cap, the lens is influenced by gravity, and the mechanical guide rail and the guide rod deform and the positive and negative deviation of the gap influence, when the magnetic sensor detects the magnetic sensing signal, the magnetic sensing horizontal detection distance can change, so that the consistency of the magnetic sensing horizontal detection distance in the resetting process is ensured, the consistency of focusing and amplifying of the single desk lamp on the vertical resetting zero position can be ensured to a great extent, the resetting consistency of the single lamp in different time periods is further ensured, and meanwhile, the consistency between the lamp and the lamp is also controllable.
