I. Design principles
The design of stage lighting system is configured according to the law of stage art performance and special use requirements. According to the system engineering, design and configure all kinds of lighting technology equipment needed for the reproduction of performing arts, so that the stage lighting system can serve the art exhibition accurately and satisfactorily.
1. Create a complete stage lighting free space to meet all lighting needs;
2. In order to make the system run continuously, appropriately increase the reserves and expand the space;
3. The anti-interference ability and safety of the system are important design indexes;
4. Introducing new lamps with high efficiency and energy saving into the system design;
5.DMX5 12 digital signal network technology has been introduced into all aspects of system design.
Second, the process requirements
The process design and equipment configuration of 1. system have comprehensive theater function, and the lighting operation schemes of many different operas can be rotated in a short time.
2. The system design can be quickly switched from one lighting scheme to another, and the switching time is completed within 2 hours.
3. The system allows the use of all types of lamps and other auxiliary equipment.
4. The system is designed with sufficient safety and storage capacity, and the whole system can continuously diagnose and check the main console without interrupting the main power supply.
5. The equipment in the system completely meets the technical requirements of stage background noise. In the open field, the noise of all lighting equipment and the interference of external environment noise are not higher than NR25, and the noise of test point 1M effect equipment is not higher than 30dB.
6. At the beginning of the system design, the expansion capacity of the system was reserved intentionally, such as power thyristor capacity and network capacity. In the future, when funds are abundant or new technologies appear, the system will not be modified or updated in a large area due to insufficient design to meet the needs of saving money and adapting to changes quickly.
Third, the design description
The position of the ceiling lamp and the stage lamp constitutes a light distribution array, and all parts of the stage have spots to prevent blind spots, which can be flexibly combined according to needs.
1, design and configuration of ceiling lamp system
The function of the dome light is to provide necessary lighting for the performance space in the depth of the stage. Various lamps used in the overhead lamp configuration greatly improve the light transmittance, and can be used for light distribution or dyeing of the overhead lamp on the stage.
A. the distribution of lamps and lanterns is as follows:
Above the stage, there are 20 overhead light suspenders. Wherein each ceiling lamp uses a different number of lamps.
B. Arrangement and projection method of lamps and lanterns:
The first top lamp is connected with the surface lamp to illuminate the starring area. Pay attention to the height of characters when connecting. The first top light can be used as fixed-point light and special effect light, and some lights are selected to strengthen the lighting of the fulcrum of the performance area. The second to tenth lanes can be projected directly behind the stage or vertically downward, which can strengthen the modeling of stage characters and the lighting of the set space. The front and rear lights are connected, which makes the stage performance area get more uniform color and brightness.
2. Design and configuration of computer lights
The computer lamp is mainly installed on the overhead lamp pole above the stage, and the projection angle, brightness, pattern change, beam size, color and other functions can be adjusted at will to ensure that the performance meets the requirements of computer lamp change.
3. Design and configuration of photochromic device
The color changers installed on some lamps play the role of stage lighting, dyeing, color change and setting off the plot, achieving colorful effects.
Fourth, the equipment configuration
1, lighting console
2. Dimming silicon cabinet
