Stage lighting dimming equipment, is now basically using a thyristor as a dimmer to adjust the dimmer through the console control to achieve the control of the lighting changes in light and shade. There are several types of dimming console: According to the control signal points, there are analog dimming Taiwan, digital dimming Taiwan, and now analog dimming console gradually replaced by digital dimming: according to the use of points, there are architectural lighting dimming , The studio dimming station, due to the use of different venues, dimming control capacity, adjust the function of a slight difference. In this paper, a number of application of technical indicators as a measure of the current domestic commonly used in Britain and the United States and other countries to compare several computer dimming console, according to the size of the console, the scope of use, the basic functions of the application of a simple classification for peer selection Reference。
First, small computer dimming table
The so-called small dimming console, the general control of the optical path is less than 100 light path, and dimmer up to 1024 loop, through the console with the dimmer in accordance with the requirements of different purposes with a different optical path. Small dimmers by the optical path of the restrictions in the number of lamps when the lamp can not be achieved for all the fine fine dimming, there must be some different dimmers on the same light control by the light path, but only the same output ratio Power output.
Small dimming console manual putter more generally have 48, and some even up to 96, and set the control putter less, up to only 24. The expansion of the control fader is achieved through the centralized control paging. To a large extent, a small dimming console is a digital analog dimming console. As the manual control of the lamp on the console of the direct control is very intuitive, more suitable for some non-professional lighting personnel to use.
Small dimmers smaller, lighter weight, in addition to fixed use, but also easy to install and place, more suitable for mobile performance use. Especially the British series of Strand (Sri Lanka) made 300 series portable dimming console. The console is a folding notebook-style console, a small, modular combination of design, but also by a number of such a folding console connected into a large control system, the function has been a large complex The basic performance of the system is the preferred device for mobile performance, is the dream designer of the lighting designer.
Small-scale dimming table, the most suitable for basic lighting as the main control of the place, such as news studios, special programs studio, large conference rooms, school teaching and research room, conference hall, large exhibition activities, entertainment clubs, As well as building outdoor and indoor environment lighting.
Second, medium computer dimming table
The so-called medium-sized dimmer, the general control of the optical path has 100 ~ 500 light
path, dimmer up to 1024 loop. In general, the console of the dimming path with the total number of dimmers is selected, and the one-to-one mating method of the dimming optical path and the dimming circuit is realized through the console's mating so that the programming, The fine adjustment of the loop has the greatest flexibility, which is the ideal control system for every lighting designer.
Medium-sized dimmer has no manual putter, all the light information must be pre-through the field adjustment, programming storage to the console, performance repeating to group, effect, centralized control, field as the basic elements, repeat the programming design, Control, field control repeat putt rehearsal programming program, to achieve on-site lighting in accordance with the concept of lighting designers continuous change. Medium-sized dimmer repeating programming design, has a very large flexibility in the stage scene to change the lighting effect on the process of cross-change process, it can be manual exchange field, you can also through programming, given the end of a certain start, end Of the time, enter the performance of the time and the middle of the time to achieve the required cross-field change, get a very natural, no trace of the process of change.
Medium-sized dimmers include Strand 300 125/50 Strand 300 400/600 and 500 series Strand 520i produced by Strand in the UK. Express 125/250, Insight, Expression 3 produced by ETC, USA Companite produced by Compulite Compulite Photon, Compulite Spark, pheonix2 produced by ADB, Belgium: Zero 88 Sirius 500, Zero 88 Illusion 120, UK Zero Corporation.
Medium-sized dimmer Taiwan's product line more widely used. Mainly used in small and medium-sized studio, song and dance theater, large nightclub, Disco club, the general flow of theatrical performances, comprehensive halls, squares, and large-scale building outdoor lighting.
Third, large computer dimming table
Today's large-scale dimmers, with today's most advanced electronic technology and computer technology, into a lot of lighting design rich experience in design and advanced design ideas, represents the highest level of today's dimming technology. Large dimming console dimming optical path are more than 1000, can control the dimmer are more than 2048. The controllable capacity of the dimmer is no longer a concern for the lighting designer.
Large-scale dimming console performances repeat, are through the control putter, field repeat putter, for lighting designers, a large dimming console control hundreds of thousands of lamps, to do with the show Out of the continuous seamless changes, so complex and heavy tasks are * dimming console programming to achieve, which requires a very flexible and simple programming methods and procedures to modify the method, because every change may be related to the Thousands of light changes, to minimize the lighting division of the programming time, reduce the energy spent on the lighting equipment, will be more time and energy on the show.
Modern stage intelligent lighting and the emergence of continuous improvement, so that it has a very common application. Intelligent lamps generally use the new and more efficient light source, dimming method, with the traditional lamps have been completely different, intelligent lighting control are generally equipped with a dedicated computer console. At present, these modern large-scale dimming table, with optical path properties set, 16-bit DMX output, a dedicated encoder to adjust the control, but also fully capable of these intelligent lighting control, especially the German Strand 500 series Dimming station, has been for different intelligent lamps to establish a database, but also by the lighting division self-built database, it is easy to mate with intelligent lamps.
Large-scale dimming console mainly the United Kingdom Strand 500 series dimming console: the United States ETC's Expression 2, Obsesion: Belgium ADB's Pheonix 1O and so on.
Large-scale dimming console is mainly used in large-scale studio, large-scale dance theater, large-scale outdoor comprehensive art show.
Lighting control specifications and techniques
As the saying goes, there is no rules into a radius. Therefore, in the control of light, can not have any arbitrary, because the light control has its own operating norms and skills, otherwise, will lead to bulbs, lamps, light console damage, and even cause a fire, causing serious losses. Here from the actual work summed up the light control of the taboo and skills, we hope to help.
The following is the actual work of the frequent misuse, in this point, cited as a mirror.
1. In the cold state of the bulb, suddenly shining bright (full) light, the result may cause the bulb "snapped" sound burst; or cause the bulb tungsten wire blown.
(1) As the bulb in the production process, the bulb of the glass shell is inevitably uneven thickness, resulting in uneven heat caused by the phenomenon. When suddenly light bulb, it will cause the bulb glass shell instantly warming, as if life to an empty glass filled with hot water the same effect.
2) After the use of light, the bulb in the heat from the process of cooling, will absorb the water molecules in the air, these water molecules will stay in the bulb glass shell gathered. When you suddenly push the light bulb, the glass shell on the water molecules, as if the hot oil pan in the same effect, the light bulb is a matter of course.
3) suddenly push the light, will cause an instantaneous impact current (rise), so easy to light bulb tungsten wire break.
Operation Tips: When the bulb in the cold state (before the opening), the console fader only push a little (often said that the calendering state), so that the light bulb, let it in a warm state, so that Its heat evenly, while evaporating condensation in the bulb glass shell on the water molecules, preheat for a few minutes, then push a little, and then preheat a few minutes before the lights can be completely shine.
2. Do not push the dome up to the state, and then open the silicon box power. The results and the above results are the same, two will damage the bulb. All the faders of the dimmer should be turned off and the silicon box power supply should be turned on.
3. Avoid switching equipment, the light console and silicon box power supply in reverse order. Turn on the power, you must first turn on the power of the light console, and then open the silicon box power; turn off the power, turn off the power of the silicon box, turn off the light console power. If you reverse the order of operation, then the line will cause all the lights are flashing, this will affect the lamp life.
4. Do not shake the light when the bulb is shining. The bulb tungsten wire will break or fall off.
Light bulbs in the light, the temperature gradually increased, the tungsten wire will also be softened accordingly, while the impact of gravity, tungsten wire also drooping accordingly (if the bulb is not using screw-like tungsten wire, this phenomenon is particularly evident) , This time when the big shake the lights, but also until the lights completely cooled, before the demolition.
2. Never replace the bulb, contact the lamp directly by hand, which will affect the light bulb, and another hidden hazard is caused by the blasting of the bulb.
1) grease on the fingers or fingers and the glass surface of the glass bulb will leave a "scars", thus affecting the lamp finish and transparency thus affect the normal light bulb illumination.
2) If there is sweat, finger and bulb "intimate" contact on the finger, the salt molecules in the sweat will absorb the water molecules in the air. Once the bulb has water, when the bulb rises rapidly, it is easy to burst.
Operation Tips: When replacing the lamp, be sure to wear gloves and then touch the lamp. If there is no gloves, can be packaged bulb sponge, plastic paper or soft paper towels wrapped, and then installed, after installation must remember to take these packages down, so as not to light up when the light bulb
6. The Should not be reflected back to the light of the light speed is too focused. Too focused will be in a short time will be installed on the lamp color of the color paper fade, loss of color, even worse, the color paper baked out a hole. If the direct distance of the lamp and flammable items too close, it is impossible to point it.
Skills: adjust the lamp when the light beam, adjust a little astigmatism as well, if it is not enough light, can add lamps
7. Do not install the color changer while forgetting to install the protective net cover, protective net cover is to prevent the bulb when the explosion splash and burn items.
Like the back light is not 2 block pendant slot, by the inside of a file is equipped with protective mesh cover, and the outside of a block is fitted with a color device, and some PAR lamps have a fixed protective net cover, Okay?
6. Remember to make the hot light source of the lamp and the flammable curtain is too "intimate". Years ago, a school in the northeast in a performance process, because the lights will be lit curtain ignited the fire, causing hundreds of casualties tragedy. Therefore, the light and the curtain to maintain a certain distance between the light is important. 300W lamps direct direction and curtains of the distance of not less than 3cm, lamps side, tail and curtain (still state) of the distance of not less than 2m, if the curtain swing is very large, it may be close to the lamp, And the middle of the curtain set up a metal isolation network, to prevent the curtains on the lamp and cause a fire. 500W or more lamps, straight curtains in the distance of 5m away, the side, tail and curtains away from the 3m away.
9. Do not install the power of the lamp more than the power specified by the manufacturer. The power carried by each circuit on the light box is described in detail in the manual. Generally each circuit carrying power is 1KW, 2KW, 3KW, 6KW. To 6KW, for example, silicon box, also known as solid-state relay solid state relay is 60A, calculate what can carry power is 13.2KW, anyway, there is such a large power space, in this circuit can be installed more than 6KW light The. I believe that only consider the bulb in the moment of the current generated by the fuse, so consider the problem is one-sided. Say that manufacturers will not be left without any reason for such a high-power SCR, which is a certain truth in the inside.
