The first part of the stage lighting design
First, stage lighting design principles
Guangzhou stage lighting stage lighting system design is to follow the rules and special requirements of the stage art performance, the purpose is to perform all kinds of art reproduction process of the lighting process equipment, according to system engineering design and configuration, so that the stage lighting system accurate and satisfactory service for art display.
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, stage lighting system design description
Lighting array stage lighting lamp location layout of top light, location, stage parts were lighting point, to eliminate the dead zone can be flexible in combination.
(1) the design and configuration of the top light system
Top light effect is on the depth of the stage performance space for lighting is necessary, the top light configuration used in all sorts of lamps and lanterns, greatly improve the transmittance of light, light transmittance than the current domestic mirror increased by 150%, shading the leaf design beautiful novel, reasonable set of four pages, good shading effect, stage top light lighting or dyeing.
The distribution of the A. is as follows:
Over the stage, a total of 20 dome light.
(2) computer lamp design configuration
Taking into account the intelligent lamp is the inevitable trend of the development of stage lighting in the 21st century, in order to meet a variety of stage lighting needs, stage lighting design configured 16 computer lamp headlight shaking.
Computer lamp is mainly arranged on stage over the top light poles were using DMX signal control, through a network of contacts connected computer console, can arbitrarily adjust the lighting angle of projection, brightness, pattern transformation, beam size, color and other functions to ensure meet the performance requirement of computer lights change.
(3) the design and configuration of the lamp for the light of the Guangzhou beam
In the light of the role of the stage light, coloring, color change, and the background of the color changing device installed on the part of the lamps and lanterns, it can achieve the effect of a variety of colors.
Color changer configuration:
WD 512 - 08A series computer for color 136.
Four, stage lighting control equipment configuration
(1) lighting control console
Lighting console select the British "Strand" company 125 series 300 - type - type light path, the use of the quality assurance of the Pro Genius operation software, the software support for the small console or tracking mode operation. Computer control is a standard lamp characteristic siquande 300 series console, it achieved through smart mouse trackball.
With over 80 years of production, manufacturing, sales, design experience of the global company, its products, the reliability and the advanced nature of our choice and the use of the owners provided the confidence.
(2) dimming silicon cabinet
The light of the cabinet is to choose the CD80 A of the British "Strand" company.
Guangzhou head lamp digital silicon cabinet is the carrier of high power load transfer and the core of the system. A - CD80 silicon cabinet is a digital decoding trigger control technology, with high control accuracy, high performance of the light regulator. Its DMX input interface uses the photoelectric isolation technology, the high precision, high speed digital trigger system (dimming range 1-100%, the adjustment curve 10, 1024 level). Anti interference, simple debugging, the system is not affected by temperature, voltage and other environmental impact, the system does not need to debug can meet the national standard of the output voltage of the output voltage consistency index, do not need to make a point of light, consistency of maintenance adjustment. The system uses the ISP on-line system to program the large-scale integrated circuit, the hardware reliability has been improved, the software adopts "watchdog" technique and fault tolerant technology. Even if the external power and transmission line is strongly interfered, the power distribution system can be automatically detected. The silicon cabinet and the light adjusting table is the transmission signal in the photoelectric isolation mode, avoiding the accident of the light leakage, the static and so on. The silicon cabinet has the function of the last function of the light memory, once the main and the secondary control are out of the fault, it can also be guaranteed.
