Description

Technical Field

[0001] The utility model relates to the technical field of stage light structures, and particularly relates to a base mechanism and a stage light for a moving head stage light. Background Art

[0002] A moving head light is a stage lighting device that can change the light projection angle in the horizontal and vertical directions. Its characteristic is that it can freely rotate up and down, left and right, and back and forth, thus generating rich dynamic lighting effects. It is one of the important components of stage lighting effects and is widely used in stages, films, exhibitions and other occasions.

[0003] The moving head light mainly includes three major parts: a base module, a U-shaped frame module, and a lamp head module.
