Compared with the related art, in the stage light of the present invention, an optical fiber is arranged between the light source module and the lamp head assembly, the light input end of the optical fiber extends into the base and is coupled with the light source module, and the light output end of the optical fiber extends to the lamp head assembly. It is internally coupled with the lamp head assembly to realize the light transmission between the light source module and the lamp head assembly through the optical fiber, so that the light source module and the lamp head assembly are arranged at intervals, that is, the separation of the light source module and the lamp head assembly is realized, and the lamp head assembly does not need to be provided with heat dissipation The device and the waterproof device simplify the structure of the stage light, reduce the kinetic energy and complexity required to rotate the lamp head assembly, and effectively improve the rotation flexibility; The inside of the second rotating shaft avoids the twisting and breaking or loss of the optical fiber due to the rotation of the lamp head assembly and the rotating device, and ensures the light transmission of the optical fiber, so that the lighting reliability of the stage light is high. In addition, the light-emitting end of the optical fiber is extended. The light is emitted to the center of the second rotating shaft, so that when the lamp head assembly rotates with the second rotating shaft, the position and angle of the light-emitting end of the optical fiber are kept unchanged, which effectively improves the lighting reliability of the stage light.

The above are only the embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, improvements can be made without departing from the inventive concept of the present utility model, but these belong to The scope of protection of the utility model.
