Detailed Implementation

[0022] Example 1, such as Figure 1-5 As shown, a rotating stage light includes a mounting base 1. A support column 4 is movably mounted inside the mounting base 1. A first motor 5 is fixedly mounted on the top surface of the support column 4. A U-shaped frame 6 is fixedly mounted to the output end of the first motor 5 via a coupling. A rotating shaft 7 is rotatably connected between the inner walls of both ends of the U-shaped frame 6. A second motor 8 is fixedly mounted on one side surface of the U-shaped frame 6. The output end of the second motor 8 is fixedly connected to the rotating shaft 7 via a coupling. A rotating plate 9 is fixedly mounted on the outer surface of the rotating shaft 7. A light body 10 is fixedly mounted on the side of the rotating plate 9. The interior of the light body 10... The system includes a multi-color LED light source module 11, which consists of multiple LED beads of different power. Each multi-color LED light source module 11 contains red, green, and blue basic color LED beads, with ≥10 beads in each group. The brightness is adjusted through PWM technology at a frequency of 1000Hz, and 256 levels of color adjustment are achieved through RGB color mixing algorithm. The first motor 5 is a stepper motor, and the second motor 8 is a servo motor. The support column 4 integrates an STM32 control system, which receives commands through a 2.4GHz wireless module to synchronously adjust the brightness and color of the light.

[0023] Reference Figure 2-3 As shown in this embodiment: the support column 4 is provided with a counterweight device 2 inside, the counterweight device 2 includes a counterweight cavity 21 opened inside the support column 4, the inner wall surface of the counterweight cavity 21 is provided with four slots 22 in a ring, the interior of each of the four slots 22 is slidably connected with a protrusion 23, and a counterweight block 24 is fixedly installed between the four protrusions 23. The outer wall surface of the support column 4 is provided with a plurality of positioning plates 25 in a ring, the surface of each of the positioning plates 25 is threaded with a bolt 26, the outer wall surface of the mounting base 1 is provided with a plurality of mounting plates 27 in a ring, the surface of each of the mounting plates 27 is provided with a threaded hole 28 that matches the bolt 26, the slots 22 are trapezoidal structures 22, and the protrusions 23 are rectangular structures.

[0024] Working principle: When the device is needed, first align the protrusion 23 of the counterweight 24 with the slot 22 inside the counterweight cavity 21, and then slide the counterweight 24 into the counterweight cavity 21. When a sufficient number of counterweights are added, align the mounting base 1 with the support column 4, so that the support column 4 is inserted into the mounting base 1, and align the bolt 26 on the positioning plate 25 with the threaded hole 28. Then screw the bolt 26 into the threaded hole 28 to complete the fixing operation between the support column 4 and the mounting base 1, and at the same time limit and fix the counterweight 24 inside the counterweight cavity 21. Then, the first motor 5 drives the U-shaped frame 6 to rotate horizontally, and the second motor 8 drives the rotating shaft 7 to adjust the vertical angle of the lamp body 10, achieving all-round lighting. Finally, wireless commands are sent through the stage control console, and the STM32 control system synchronously adjusts the PWM duty cycle and color mixing ratio of the LED beads to achieve synchronous changes in brightness and color. Through the cooperation of the above structures, the device can effectively ensure the safety and stability of the stage lamp during use by adding or removing the counterweight 24, especially reducing the risk of swaying or tipping caused by changes in the center of gravity during rotation.
