It has experienced early changes such as a control lever, multiple control levers, centralized control, and segment control equipment, but these equipment is still very complicated in the process of manual operation and cannot guarantee a better state of art.
In the late 1980 s, with the development of electronic computer technology, the use of computers to store lighting information became more and more common to replace a large number of complicated manual operations. In this century, the rapid development of digital technology, the field of professional stage lighting has gradually entered a comprehensive digital era. At present, most of the professional lighting equipment used in large-scale outdoor performance activities in China are controlled by digital.
