First, the area of ​​the outdoor performance venue is large, far larger than the general frame-style stage. Therefore, the projection distance between the lamp position and the performance area is far.
Second, the outdoor performance venue does not have the lighting system and lighting boom lifting system inherent in the frame stage. Most of them are temporarily built, whether it is the setting of the total power supply, the amount of wire, the calculation of the lamps, or the selection of the control system. When you wait for work, you almost have to start from scratch. Due to the variety and quantity of lamps used in outdoor performances, the layout of the lamp control room, the power supply room and the lamp positions must consider the rationality.
Third, the special nature of outdoor performance venues and the special requirements of the nature and content of the program, especially the requirements of the overall artistic conception of the director, require special lighting design schemes to meet, and sometimes even special lamp positions are added to complete the performance tasks.
Fourth, outdoor performances cannot be converted into scenes like theaters on stage design. Therefore, it is mainly necessary to set off lights to set off the beauty and atmosphere.
Fifth, the outdoor performance auditorium is generally three-sided audience. When the lighting is arranged, the visual needs of the left and right viewers cannot be ignored. If you have a TV broadcast or video, you need to know the relevant requirements in advance and consider it when designing the lights.
In view of the above reasons, the lighting design of outdoor performances should consider all aspects of the situation, and even in most cases, it must also take into account the lighting and connection of the surrounding natural landscape. In a sense, the lighting design of large-scale outdoor performances needs to grasp the overall space environment of the performance in a more macroscopic manner and serve the performance in a thoughtful and thoughtful manner.
