In the past ten years, with the continuous deepening and development of reform and opening up, we have also achieved unprecedented tremendous development in the field of culture and art, in order to meet the growing needs of the people in spiritual life. The performances and performances of the performances and performances are becoming more and more abundant.
The performance of the art is inseparable from the stage, and it is also inseparable from the stage lighting. Over the years, with the development of cultural performances, with the development of electronic technology in the application of stage lighting, especially the application of computer technology on the dimming console, the lighting design has added a lot of new content. The choice and application of computer dimming stations can be a top priority for lighting designers; and according to different venues, such as domestic large and medium-sized TV stations, song and dance theaters, halls, gymnasiums, art centers, etc., and different performances, different Selecting the right computer dimming station for use, etc., in order to find the most suitable application and the greatest return on investment, is an important issue that professional lighting designers should solve.
The dimming equipment for stage lighting is now basically using a thyristor as a dimmer to control the dimming of the luminaire through the console's adjustment control of the dimmer. There are several types of dimming consoles: According to the control signal, there are analog dimming stations and digital dimming stations. Today, analog dimming stations are gradually replaced by digital dimming stations: According to the purpose, there are architectural lighting dimming stations. The studio dimming station has subtle differences in the control capacity and adjustment functions of the dimming station due to the different venues used. This paper uses several applied technical indicators as the measurement standard. It compares several computer dimming stations commonly used in the United States and other countries in the country, and makes a simple classification according to the capacity, scope of application and basic function application of the console. Reference.
First, the performance comparison of small computer dimming station
The so-called small dimming station generally controls the optical path to be less than 100 optical paths, and the dimmer can reach 1024 loops. Through the matching of the console, the dimmers are connected to different optical paths according to different application requirements. The small dimming station is limited by the optical path. When the number of lamps is large, it is impossible to achieve independent fine dimming of all the lamps. It is inevitable that some lamps on different dimmers are controlled by the same optical path, but only with the same output ratio. Power output. There are more manual pushers for small dimming stations, generally 48, some even up to 96, and there are fewer centralized control putters, and there are only 24 at most. The expansion of the centralized control putter is realized by centralized control paging. To a large extent, a small dimming station is a digital analog dimming station. Because the direct control of the luminaire on the manual putter console is very intuitive, it is more suitable for some non-professional lighting personnel to operate.
The small dimming table is small in size and light in weight. It is easy to install and place in addition to fixed use, and is more suitable for mobile performance. The modulation table can be a folding notebook console, small in size, modular in combination design, or can be combined into a large control system by a plurality of such folding console connections, and the function has already been large and complicated. The basic performance of a large system is the preferred device for mobile performances and a dream combination for lighting designers. The small dimming station is most suitable for places where basic lighting is the main control purpose, such as news studios, special program studios, large conference rooms, school teaching and research rooms, conference halls, large-scale exhibition events, entertainment clubs, cafes, etc. As well as building outdoor and indoor lighting.
Second, the performance of medium-sized computer dimming station comparison The so-called medium-sized dimming station, the general control optical path has 100 ~ 500 optical path, the dimmer can reach 1024 circuit. Generally, a console with a dimming path exceeding the total number of dimmers is used as much as possible, and a one-to-one matching manner of the dimming optical path and the dimming circuit is realized through the matching of the console, so that programming, control, and each The flexibility of the primary circuit is the most flexible, which is the ideal control system for every lighting designer. The medium-sized dimming station has no manual putter, and all the lighting information must be pre-adjusted and programmed to the console through the on-site adjustment. The performance replays the group, effect, centralized control, and field as the basic elements to replay the programming design. Control and field control replay of the putter rehearsal programming program to achieve continuous changes to the scene lighting in accordance with the lighting designer's vision. The re-programming design of the medium-sized dimming station has great flexibility. The process of changing the lighting effect in the stage and scene changes in the stage scene can be done by manual cross-change, or by programming, giving a certain start to the field. The end time, the time of entering the show, and the time of the middle continue to achieve the desired cross-change, resulting in a very natural, non-marking change process. The medium-sized dimming station has a wide range of products and is widely used. Mainly used in small and medium-sized studios, dance theaters, large nightclubs, Disco clubs, general mobile art performances, comprehensive halls, squares, and large-scale outdoor lighting.
Third, the performance comparison of large computer dimming station
Today's large-scale dimming stations, with today's most advanced electronic technology and computer technology, incorporate a wealth of design experience and advanced design ideas in lighting design, representing the highest level of today's dimming technology. The dimming light path of the large dimming station is above 1000, and the controllable dimmers are all above 2048. The controllable capacity of the dimming console is no longer a concern for lighting designers. The re-enactment of the large dimming consoles is performed by the centralized control putter and the field replaying putter. For the lighting designer, a large dimming station controls hundreds of thousands of lamps, which must be done with the performance. Seamless and seamless changes, such complicated and arduous tasks are realized by dimming station programming, which requires the dimmer station to have a very flexible and simple programming method and program modification method, because each change may involve Thousands of changes in lighting, to minimize the lighting engineer's programming time, reduce the energy spent on lighting equipment, and put more time and energy on the performance. The emergence and continuous improvement of modern stage intelligent lighting makes it a very common application. Intelligent luminaires generally adopt new and more efficient illuminating light sources, and the dimming method is completely different from traditional luminaires. The control of intelligent luminaires is generally equipped with a dedicated computer console. At present, these modern large-scale dimming stations have optical path attribute setting, 16-bit DMX output, and have dedicated encoders for adjustment and control. They are also fully capable of controlling these intelligent lamps, especially already having a dimming station. A database is built for different smart lamps, and the lighter can also build a database for it, which is convenient for matching smart lamps. Large-scale dimming stations are mainly used in large-scale studios, large-scale song and dance theaters, and large-scale outdoor integrated art evenings.
Fourth, the conclusion
It can be seen from the above that the technology is advanced, the function is powerful, and the controllable loop is common to all computer dimming stations. Some large-scale computer dimming stations have network functions, which represent the current development direction of international advanced lighting digital technology. Resource sharing, multi-point control, remote control and technical support, design for lighting designers to change the scene for desktop design, Intronet computer networking provides practical technical means, especially using the world's leading Pentium II processor and international TCP /IP communication protocol, increasing the technical forward-looking and compatibility of its "Shownet" network system, enabling the main and standby consoles to learn from each other and operate in parallel to ensure the control of the show or conference lighting is truly a foolproof dimming station. Unparalleled use value and broad application vision.
