Taking the West Lake Night as an example, the architectural design of the theater stage is a mirror-frame stage design, with the stage opening 22 meters wide, the stage 16.8 meters deep, and the stage opening 10 meters high. The stage is mainly to meet the needs of large and medium-sized important meetings as a multi-functional venue for performing various arts, singing and dancing performances. It is necessary to design the stage lighting program according to this functional positioning. The plan design should strive to reflect the meeting-oriented and people-oriented design ideas. In the stage lighting design, it is also necessary to fully consider the cooperation of lighting, stage machinery and other related professions, and technically ensure that the stage becomes a first-class meeting and performance venue.
