The stage lighting system design is to follow the rules and special requirements of the stage art performance. The purpose of Guangzhou stage lighting is to design and configure all kinds of performance art, according to the system engineering.
Stage lighting design principles and settings
First, stage lighting design principles
The 1 stage lighting to create completely free space, adapt to all lighting requirements;
2 in order to make the system can continue to run, the appropriate increase in reserves and expansion space;
3 system anti-interference ability and safety as an important design index;
4 high efficiency energy-saving cold new lamps are introduced in the design of the system;
5.DMX512 digital signal network technology is introduced into the various aspects of the system design.
Two, stage lighting system design requirements
1. The system process design and equipment configuration has the use function of the theatre complex, the rotation of a variety of different genres of light operation scheme in a short period of time.
2 the system design can be from one kind of lighting scheme to convert to another one kind of lighting scheme, the conversion time is finished in 2 hours.
3 the system allows the use of all types of configurations of various types of lamps and other supplementary equipment.
4. The design of the system has enough safety and storage capacity, the system under the premise of not interrupting the main electricity supply. On the console for constant checking and diagnosis.
5. The system of equipment fully comply with the technical requirements of the stage background noise, open stope, open all lighting equipment noise and external noise interference not higher than nr25, test point 1m effect equipment noise is not greater than 30 dB.
6 system expansion capability is the system design of the initial intention to set aside, such as power silicon control capacity, network capacity, to be future funding or new technologies appear, so that the system is not due to the design of the large area of change or update, to save money and quickly adapt to change.
Three, lighting electrical equipment cabinet set
1 the structure, electrical equipment, the cabinets and racks are used in the process of metal and steel production, if necessary, with steel or steel frame to strengthen. Electrical equipment cabinet has dust and moisture measures. In addition to the ventilation and the import and export of all cables, cabinets and racks are all closed. The depth of each cabinet can be ensured by proper equipment and wiring space. Each of the specific groups of the cabinet is the same depth, height and color.
2 ventilation, all electrical components or devices can be used in continuous operation in the housing and provisions of the environment. Guangzhou beam lamp cabinet is equipped with appropriate natural pass. In order to disperse the heat generated by the equipment, through the mouth with fine foam or barrier protection, to prevent debris into the. The shell should be pressurized seal and the wind required to leak.
3 cable and cable hole in the factory according to the required location reserved; and with a removable plate for the final processing in the field. Cable in the cable out and out of the cable, laying the way and enough bending radius, and a cable fixing device.
4 cabinet doors and inspection panels, doors and panels are designed to have sufficient rigidity, doors and panels can be disassembled and maintenance, the panel is equipped with a dust seal. All the case and the panel are thoroughly to remove grease and rust paint drying paint.
5 mark, the part mark in the equipment cabinet should also be a permanent mark, and may not be used to seal the mark or the pen identification mark. Nameplate and logo size large enough in normal light, a distance of 2 meters can see the nameplate and the symbol file.
Four, lighting system, electrical cable and wiring
All of the 1 wire output socket to the silicon cabinet, by the three lines the same length, the output. Light lines and audio, video and other signal lines are far from each other, must be met when the 90 degrees cross, leaving a 0.5M distance; can not avoid the need to be parallel, the spacing is greater than 1M.
2 all signal connection cable are selected five core shielded to prevent interference.
3 a separate grounding line, power cable and wire lamp should be installed in the metal wire groove, metal wire slot should be grounded.
Between the 4 electrical socket box separated by the metal plate, to avoid the interference of the weak, weak security guarantee system.
5. The low smoke (LSF), flame retardant PVC type copper core cable, the cable should be long-term work in 90 DEG C environment, under normal conditions of use, life must be 30 years above.
6 socket box with the "national standard" enterprise production of the international advanced products, insert box strong, weak between the metal separator, ensure the safety, is conducive to electromagnetic compatibility.
For fire detection using heat sensitive cable 7 cable bridge, cable fire prevention.
8 bridge or line groove, and the fire. Power cable and control cable model, voltage, load flow, cross section, core number, the service should meet the requirements of its circuit type, transmission type, the use of environment and laying mode, and comply with the relevant specifications.
9 the control and power cable of the moving parts to meet the requirements of fire prevention and soft cable. The laying of the cable shall be in accordance with the requirements of the GB50258-96 "electrical installation engineering 1KV and the following code for construction inspection and acceptance".
10 when laying the cable should be reduced to the minimum electromagnetic interference. When using the cable hose, its length can not exceed 1 meters. Power or control line with the suspension or sagging of the soft cable shall be provided with the stress release center line, the ends of the two ends should be clamped to release the lead stress.
