[0026] The actual operation steps are as follows: S1, light deformation: start the reciprocating drive mechanism 5, and make the lamp tube 2 swing back and forth for illumination. During the swinging period of the lamp tube 2, it is linked with the light deformation mechanism 6, so that the illumination lamp 613 can be continuously moved and adjusted during the swinging period of the lamp tube 2. During the moving illumination period, the two illumination lamps 613 on the top of the same Z-shaped pad 610 are synchronously engaged with the hollow column 609, the gear 614 and the tooth plate 615, so that the two illumination lamps 613 on the top of the Z-shaped pad 610 are synchronously rotated to form an aperture capable of moving illumination; The specific operation steps are as follows: start the driving motor 501, the driving motor 501 drives the reciprocating screw 502 to rotate, the reciprocating screw 502 rotates the threaded sleeve 503 on its surface to carry the tooth meshing plate 504 to move back and forth, the tooth meshing plate 504 reciprocates and meshes with the gear sleeve 505, so that the swing shaft 4 carries the support plate 3 and the lamp tube 2 to swing back and forth in the irradiation direction; During the rotation of the lamp tube 2, the short column 603 and the rectangular frame 604 are synchronously driven to swing. During the rotation and swinging of the rectangular frame 604, the arc-shaped extrusion frame 602 lifts and squeezes the rectangular frame 604, prompting the rectangular frame 604 to drive the short column 603 to rise. The rising of the short column 603 lifts the gathering plate 608, prompting the gathering plate 608 to automatically adjust the rotation angle, thereby pushing the cross slider 607. The movement of the cross slider 607 drives the hollow column 609, the Z-shaped pad 610 and the lighting lamp 613 to move. The movement of the hollow column 609 synchronously drives the gear 614 to move. The gear 614 moves and meshes with the tooth plate 615, prompting the hollow column 609 and the Z-shaped pad 610 to drive the two lighting lamps 613 to rotate and illuminate; S2, dynamic cross-irradiation: When the two illuminators 613 on the top of the Z-shaped pad 610 rotate to form an illuminator aperture, the L-shaped toothed plate 705 in the mounting box 611 will form an extrusion fit with the cam 702, prompting the two illuminators 613 on the top of the Z-shaped pad 610 to adjust the irradiation angle synchronously, thereby changing the aperture size illuminated by the two illuminators 613; The specific operation steps are as follows: when the above-mentioned hollow column 609 and Z-shaped pad 610 drive the two illuminating lamps 613 to rotate, the installation box 611 on the top of the Z-shaped pad 610 synchronously drives the L-shaped toothed plate 705 to rotate, and the L-shaped toothed plate 705 rotates and moves along the surface of the cam 702. The movement of the L-shaped toothed plate 705 is squeezed by the convex arc of the cam 702, so that the L-shaped toothed plate 705 is continuously retracted into the installation box 611, and the movement of the L-shaped toothed plate 705 is synchronously engaged with the adjustment gear 704, so that the rotating rod 703 drives the illuminating lamp 613 to adjust the irradiation angle; S3, intermittent dust blowing: When the lamp tube 2 carrying the numerous lighting lamps 613 is swinging, the lamp tube 2 will be at the extreme position of the left and right swing, and the blowing mechanism 8 will be synchronously linked to operate, so that the heat dissipation wind discharged from the wind tube 801 will flow into the air guide inner groove 803 along the ventilation pipe 805, and then the dust will be intermittently blown from the top of the light-transmitting shielding plate 806; The specific operation steps are as follows: when the lamp tube 2 is driven by the reciprocating drive mechanism 5 to swing and adjust the irradiation direction, the cooling fan 802 is started synchronously, so that the cooling fan 802 dissipates heat inside the lamp tube 2, and the hot air blown by the cooling fan 802 is discharged from the bottom of the air tube 801; In the process of the lamp tube 2 swinging back and forth to the left and right extreme positions, the lamp tube 2 synchronously drives the sealing plate 807 to swing, and the sealing plate 807 drives the support handle 808 to move. During the rotation and swinging process, the support handle 808 gradually comes into contact with the arc-shaped inclined surface of the special-shaped double-sided inclined block 809, and then when the lamp tube 2 swings to the extreme position in one direction, the support handle 808 is squeezed and pushed by the special-shaped double-sided inclined block 809, prompting the support handle 808 to drive the sealing plate 807 to temporarily close the bottom of the wind tube 801, and the heat dissipation air inside the closed wind tube 801 will be transmitted from the ventilation pipe 805, and finally transmitted to the interior of the air guide inner groove 803, and blown through the wind hole 804, and the light-transmitting shielding plate 806 in the lamp tube 2 is in an inclined state, and is tilted and blown downward from the high point wind hole 804.
