[0021] Referring to Figures 1-4 , a stage moving head light with adjustable brightness provided by the present utility model includes a base 1. The left and right sides above the base 1 are connected to a rotating frame 2 through fixed shafts. The inner side above the base 1 is provided with a stage light body 3. The middle of the lower part inside the base 1 is inserted and fixed by a stepper motor 12. The front top end of the output shaft of the stepper motor 12 is welded to the middle of the rear end face of a central plate 4. A circular frame 5 is welded to the outside of the central plate 4. A first circular plate 6, a second circular plate 7, a third circular plate 8, and a fourth circular plate 9 are placed behind the inner side of the circular frame 5.

A tensile spring 14 is welded to the outside of the end of the pulling block 10 close to the connecting rod 13. The rear end face of the circular frame 5 contacts the front end face of the stage light body 3. The rubber layer 15 contacts the front side edges of the first circular plate 6, the second circular plate 7, the third circular plate 8, and the fourth circular plate 9. The outside of the stop bar 11 is slidably connected to the inside of the circular frame 5. The end of the tensile spring 14 away from the pulling block 10 is fixed to the outer edge of the circular frame 5. The inner side of the tensile spring 14 is slidably connected to the outside of the connecting rod 13. When the stepper motor 12 drives the central plate 4 to rotate by 90 degrees, it is convenient for the circular frame 5 and the corresponding first circular plate 6, second circular plate 7, third circular plate 8, and fourth circular plate 9 of the color to be attached to the light-emitting end of the stage light body 3, so as to achieve the purpose of changing the irradiation color, brightness, etc. of the stage light body 3 without adjusting the optical elements inside the lamp body.

[0023] As a further implementation scheme of the above technical scheme: the stepper motor 12 needs four times to drive the center plate 4 to rotate one circle, and the angle of rotation of the stepper motor 12 is ninety degrees. When the stepper motor 12 rotates once, the round frame 5 can be fixed at the irradiation end position of the stage light body 3.
[0024] As a further implementation scheme of the above technical scheme: a limiting plate is provided on the rear end face of the circular frame 5, and the inner diameter of the limiting plate is one centimeter smaller than the inner diameter of the circular frame 5, and the longitudinal section diameters of the first circular plate 6, the second circular plate 7, the third circular plate 8 and the fourth circular plate 9 match the inner diameter of the circular frame 5, so that the first circular plate 6, the second circular plate 7, the third circular plate 8 and the fourth circular plate 9 can be respectively restricted to the inner rear of the circular frame 5, preventing the first circular plate 6, the second circular plate 7, the third circular plate 8 and the fourth circular plate 9 from escaping from the restriction of the circular frame 5 from the rear of the circular frame 5.
[0025] As a further implementation scheme of the above technical scheme: there are two connecting rods 13 inside the circular frame 5, and the connecting rods 13 on the upper and lower sides of the center plate 4 are distributed in the middle of the left and right sides of the circular frame 5, and the connecting rods 13 on the left and right sides of the center plate 4 are distributed in the middle of the upper and lower sides of the circular frame 5. The length of the connecting rod 13 is 1.5 times the wall thickness of the circular frame 5, so that the purpose of pulling the connecting rod 13 can be achieved to take out the first disc 6, the second disc 7, the third disc 8 and the fourth disc 9 from the inner rear of the circular frame 5.
[0026] As a further implementation scheme of the above technical scheme: square grooves are provided on the inner edges of the circular frame 5 on both sides, and the longitudinal section shape and depth of the square grooves on the inner edges of the circular frame 5 on both sides match the longitudinal section shape and left and right length of the baffle 11; the inner centers of the square grooves on the inner edges of the circular frame 5 on both sides are provided with interconnected circular through holes, and the diameter of the circular holes matches the longitudinal section diameter of the connecting rod 13; a manually retractable baffle 11 is provided on the inner side of the circular frame 5; the baffle 11 can limit the first circular piece 6, the second circular piece 7, the third circular piece 8 and the fourth circular piece 9 on the inner side of the circular frame 5 to prevent the first circular piece 6, the second circular piece 7, the third circular piece 8 and the fourth circular piece 9 from detaching from the inner side of the circular frame 5 when they are driven by the stepping motor 12 to rotate, thereby improving the stability of the first circular piece 6, the second circular piece 7, the third circular piece 8 and the fourth circular piece 9 on the inner side of the circular frame 5 to a certain extent.
[0027] Working principle:
[0028] When using the present utility model, select the first disc 6, the second disc 7, the third disc 8 and the fourth disc 9 with different colors and transparencies according to your own needs. Install the first disc 6 in the circular frame 5 above the central plate 4, the second disc 7 in the circular frame 5 on the left side of the central plate 4, the third disc 8 in the circular frame 5 below the central plate 4, and the fourth disc 9 in the circular frame 5 on the right side of the central plate 4. When installing the first disc 6, the second disc 7, the third disc 8 and the fourth disc 9, the operator needs to place two fingers on the position of the pulling block 10 outside the circular frame 5 and move them outward. The pulling block 10 drives the connecting rod 13 and the stop bar 11 at the inner top end of the connecting rod 13 to move outward, and the tension spring 14 deforms until the stop bar 11 completely retracts into the square groove opened on the inner wall of the circular frame 5. The operator pushes the first disc 6, the second disc 7, the third disc 8 and the fourth disc 9 backward inside the circular frame 5. After reaching the top, release the pulling block 10, and the tension spring 14 drives the connecting rod 13 and the stop bar 11 to rebound. At this time, the stop bar 11 blocks the front edges of the first disc 6, the second disc 7, the third disc 8 and the fourth disc 9, and the rubber layer 15 also contacts the front edges of the first disc 6, the second disc 7, the third disc 8 and the fourth disc 9. After the installation is completed, connect the rotating frame 2 with the driving device, and the installation is completed. If it is necessary to adjust the irradiation brightness or color of the stage light body 3, just start the stepping motor 12 inside the base 1. The stepping motor 12 rotates once, and the angle of one rotation of the stepping motor 12 is 90 degrees. The stepping motor 12 drives the central plate 4 and the circular frame 5 outside the central plate 4 to rotate, so as to achieve the purpose of changing the irradiation color, brightness, etc. of the stage light body 3 without adjusting the optical elements inside the lamp body.
[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
