This article mainly introduces the stage lighting control system of the Century Hall (2,500 seats).
Century Hall basic parameters:
Venue area: 1331m2
The rostrum (stage): the width of the platform is 23m, the height is 13m, and the depth is 43m.
Seating: 195 seats on the podium; the auditorium has fixed seats, 1172 on the first floor, 805 on the second floor and 650 on the third floor.
Second, the stage lighting system design indicators
Designing a stage lighting system for a modern theater, in addition to considering the architectural form and functional requirements of the theater, it is also necessary to analyze the use of the theater and how the future performances are arranged, taking into account the most complicated forms of stage lighting. On the basis of fully drawing on the experience of successful cases in this field, Baiyun International Conference Center combines the stage design practice in China and selects the conference and stage lighting system suitable for the special use of the conference center for the convenience of domestic and foreign performance groups.

Illumination index: the vertical illumination of the main performance area is not less than 1500Lux;
Conference lighting: no less than 550Lux;
Color rendering index: Ra>90;
Color temperature: 3200K±150K for conventional lamps and 4700K-5600K for special effects lamps;
Dual network dual backup digital lighting control system, working power in the network cable, the main and standby dimming stations completely track backup;
Network speed: 1GT bits/second;
Output power: up to 10 kW per channel, minimum 3 kW, maximum output voltage adjustable;
Dimming cabinet anti-interference index: 400us (230V), the density will not change when the current load is increased to 100A;
Trigger accuracy: 16 bits and 4000 levels.
Third, the use of stage lighting system functions and management requirements
