However, the dynamic projection lamp still has the following problems.

[0004] During the stage auxiliary use, the dynamic projection lamp is needed to illuminate and project the image onto the stage.

[0040] The method of using the stage auxiliary dynamic projection lamp of the present invention is as follows:

[0041] Step 1: When installing the projection, first install the mounting frame 39 on the center suspension frame of the stage, and firmly fix the mounting frame 39 and the center suspension frame of the stage with bolts, so that the mounting frame 39 supports the rotating motor 38, the rotating motor 38 supports the sleeve block 30, the sleeve block 30 supports the rotating shaft 29, and the rotating shaft 29 provides support for the sleeve rotating rod 28.

[0042] At the same time, the wireless controller 40 turns on the lamp beads 14 inside the multiple lamp housings 10, and the lamp beads 14 illuminate the slide 15, so that the slide 15 projects the image outward through the double convex lens 16, so that the images on the multiple lamp housings 10 can be projected onto the stage.

[0043] Step 2: When the tilt is adjusted synchronously and dynamically, the reduction motor 37 is started through the wireless controller 40, and the reduction motor 37 drives the screw rod 34 to rotate, and the screw rod 34 rotates inside the sliding frame 35. At the same time, the screw rod 34 drives the threaded sleeve 33 to move upward under the action of the thread transmission force, and the threaded sleeve 33 moves upward along the inner wall of the sliding frame 35. The threaded sleeve 33 drives the driving rack 32 to move upward, and the driving rack 32 makes the rotating gear 31 rotate counterclockwise, and the rotating gear 31 drives the rotating shaft 29 to rotate counterclockwise. At the same time, the rotating shaft 29 rotates counterclockwise inside the sleeve block 30, and the rotating shaft 29 drives the sleeve rotating rod 28 to rotate counterclockwise, and the sleeve rotating rod 28 realizes tilt rotation, and the sleeve rotating rod 28 drives the pillar 12 to rotate counterclockwise, and the pillar 12 drives the linkage electric cylinder 17 to rotate counterclockwise, and the linkage electric cylinder 17 drives the lamp stand 1 to rotate counterclockwise, and the lamp stand 1 simultaneously drives multiple support rods 26 to rotate counterclockwise, and the support rod 26 drives the sliding frame 25 to rotate counterclockwise, and the sliding frame 25 makes the articulated sleeve block 23 rotate counterclockwise, and the articulated sleeve block 23 drives the guide arc rod 27 to rotate counterclockwise.

[0044] At the same time, the guide arc rod 27 drives the sleeve plate 9 to rotate counterclockwise, and the sleeve plate 9 drives the lamp housing 10 to rotate counterclockwise, so that multiple lamp housings 10 can be tilted synchronously for dynamic adjustment, and the reduction motor 37 is turned off by the wireless controller 40 after adjustment.

[0045] Step three, during vertical synchronous dynamic adjustment, the wireless controller 40 starts the electric cylinder 2, and the lamp frame 1 supports the bracket 13, the bracket 13 supports the electric cylinder 2, the electric cylinder 2 pushes the ring frame 3 to move downward, the ring frame 3 makes multiple racks 4 move downward synchronously, the rack 4 drives the linkage gear ring 5 to rotate vertically counterclockwise, the linkage gear ring 5 drives the swivel 6 to rotate vertically counterclockwise, the linkage gear ring 5 and the swivel 6 both rotate vertically counterclockwise on the outer wall of the positioning shaft 11, the swivel 6 drives the hinge bar 7 to rotate vertically counterclockwise, the hinge bar 7 drives the connecting shaft 8 to rotate vertically counterclockwise, the connecting shaft 8 drives the sleeve plate 9 to rotate vertically counterclockwise, the sleeve plate 9 makes the lamp housing 10 rotate vertically counterclockwise, the lamp housing 10 drives the lamp beads 14 to rotate vertically counterclockwise, and at the same time, the lamp housing 10 drives the projection film 15 and the double convex lens 16 to rotate vertically counterclockwise synchronously.

[0046] At the same time, the sleeve plate 9 rotates vertically counterclockwise along the outer wall of the guide arc rod 27, and the projection images on multiple lamp housings 10 can be dynamically adjusted vertically synchronously without adjusting the vertical angles one by one. The synchronous adjustment efficiency is higher, and the stage operation is more time-saving and labor-saving.

[0047] Step 4: During the horizontal synchronous dynamic adjustment, the linkage electric cylinder 17 is started through the wireless controller 40, and the linkage electric cylinder 17 pushes the linkage bar 18 downward, and the linkage bar 18 makes the multiple hinge blocks 19 move downward, and the multiple hinge blocks 19 respectively drive the multiple push shafts 20 to move downward, and the push shafts 20 make the top of the sleeve rod 21 move downward, and the bottom end of the sleeve rod 21 drives the linkage shaft 22 to move right, and the linkage shaft 22 makes the hinge sleeve block 23 move right. At the same time, the hinge sleeve block 23 slides rightward along the outer wall of the guide column 24, and the hinge sleeve block 23 slides rightward along the inner wall of the slide frame 25, and the lamp frame 1 supports the support rod 26, and the support rod 26 supports the slide frame 25, so that the hinge sleeve block 23 can stably slide rightward along the inner wall of the slide frame 25.

[0048] At the same time, the hinged sleeve block 23 drives the guide arc rod 27 to move right, the guide arc rod 27 drives the sleeve plate 9 to rotate horizontally counterclockwise, the sleeve plate 9 rotates horizontally counterclockwise on the outer wall of the connecting shaft 8, the sleeve plate 9 drives the lamp housing 10 to rotate horizontally counterclockwise, the lamp housing 10 drives the lamp beads 14 to rotate horizontally counterclockwise, and the lamp housing 10 drives the projection film 15 and the double convex lens 16 to rotate horizontally counterclockwise at the same time, so that the projected images on multiple lamp housings 10 can be dynamically adjusted horizontally synchronously. When used as a stage auxiliary, the projected images on multiple lamp housings 10 can be adjusted synchronously without adjusting the projection parts one by one, so that the adjustable efficiency of projection is greatly improved.
