[0014] The present invention provides a stage lighting rotating device and a stage lighting system. Compared with the existing technology, it has the following advantages:

[0015] (1) The stage lighting rotating device and stage lighting system are provided with a light deformation mechanism, an aperture self-adjusting mechanism and a purge mechanism between the supporting bottom frame and the lamp tube, so that the lamp tube is controlled by the reciprocating drive mechanism to swing and illuminate. The device can also, through the coordinated cooperation of the light deformation mechanism, the aperture self-adjusting mechanism and the purge mechanism, prompt the lighting lamp in the lamp tube to move and adjust the illumination position while the lamp tube swings.

[0017] When the lamp tube swings to the extreme position left or right, the lamp tube automatically blows from the high point to the low point of the light-transmitting shield plate through the blowing mechanism to ensure the cleanliness of the light-transmitting shield plate.

[0018] (2) The stage lighting rotating device and the stage lighting system are configured to symmetrically rotate guide rollers inside the rectangular frame, so that when the rectangular frame is slid and extruded along the surface of the semi-circular arc plate and the arc extrusion frame, the rectangular frame can reduce the resistance between the rectangular frame and the semi-circular arc plate and the arc extrusion frame through the rotation of the guide rollers.

[0041] The present invention also discloses a stage lighting system, including a stage lighting rotating device and an external controller thereof, wherein the external controller is used to control the opening and closing of a driving motor 501, a cooling fan 802, and a lighting lamp 613.

[0042] The actual steps are as follows:

[0043] S1. Light deformation: The reciprocating drive mechanism 5 is activated to cause the lamp tube 2 to swing back and forth for illumination. During the swinging period, the lamp tube 2 is linked to the light deformation mechanism 6, causing the illumination lamp 613 to continuously move and adjust its illumination position along with 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 rotated through the meshing cooperation of the hollow column 609, the gear 614 and the tooth plate 615, forming an aperture capable of moving illumination;

[0044] The specific operation steps are as follows: start the drive motor 501, which drives the reciprocating screw 502 to rotate. The reciprocating screw 502 rotates the threaded sleeve 503 on its surface, carrying the tooth meshing plate 504 to move back and forth. The tooth meshing plate 504 reciprocates and meshes with the gear sleeve 505, causing the swing shaft 4 to carry the support plate 3 and the lamp tube 2 to swing back and forth in the illumination direction;

[0045] 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, it is lifted and squeezed by the arc-shaped extrusion frame 602, prompting the rectangular frame 604 to drive the short column 603 to rise. The rising 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 engages 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.

[0046] S2. Dynamic cross-illumination: As the two lamps 613 on top of the Z-shaped backing plate 610 rotate to form an illumination aperture, the L-shaped toothed plate 705 in the mounting box 611 forms a squeeze fit with the cam 702, prompting the two lamps 613 on top of the Z-shaped backing plate 613 to adjust their illumination angles synchronously, thereby changing the size of the aperture illuminated by the two lamps 613.

[0047] The specific operation steps are as follows: when the hollow column 609 and the Z-shaped pad 610 drive the two illuminating lamps 613 to rotate, the mounting box 611 on the top of the Z-shaped pad 610 synchronously drives the L-shaped toothed plate 705 to rotate. The rotation of the L-shaped toothed plate 705 moves along the surface of the cam 702. The movement of the L-shaped toothed plate 705 is squeezed by the convex curvature of the cam 702, prompting the L-shaped toothed plate 705 to continuously retract into the interior of the mounting box 611. The movement of the L-shaped toothed plate 705 is synchronously engaged with the adjustment gear 704, prompting the rotating rod 703 to drive the illuminating lamp 613 to adjust the illumination angle.

[0048] 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 left and right swing position, and the synchronous linkage blowing mechanism 8 will operate, causing the heat dissipation air discharged from the air tube 801 to flow into the air guide inner groove 803 along the ventilation pipe 805, thereby intermittently blowing dust off the top of the light-transmitting shield 806;

[0049] 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 to promote the cooling fan 802 to dissipate heat inside the lamp tube 2. The hot air blown by the cooling fan 802 will be discharged from the bottom of the air tube 801.

[0050] 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 blocking plate 807 to swing, and the blocking plate 807 drives the support handle 808 to move. During the rotation and swinging process, the support handle 808 gradually squeezes and contacts the arc-shaped inclined surface of the special-shaped bilateral oblique 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 bilateral oblique block 809, prompting the support handle 808 to drive the blocking plate 807 to temporarily close the bottom of the wind tube 801. 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 a tilted state, and is tilted and blown downward from the high point wind hole 804.
