Intelligent Lighting
History
There are many patents in 1906 when Edmund Sohlberg Kansas City. The lantern uses a carbon arc lamp and was not actuated by a motor or any other form of electronics, but with ropes, which were operated manually to control Pan, tilt and zoom.
1925, the first use of electric motors used to move the device, and with it the beam position by Herbert F. King. Patent number: 1680685. In 1936, the patent number, 2,054,224, received a similar device, but where are the Pan and Tilt controlled by joystick, however, is to pass. From that time until 1969, made various other inventors such as lighting and improved technology, but without major breakthroughs. Meanwhile, began lighting centuary (now Strand) of such a detail Units specifically to order, each of its renovation of existing lamps up to 750 watts in the control pan and tilt.
George Izenour made the next breakthrough 1969 with the first device to use a mirror on the end of an elliptical, the distance to redirect the light beam. In 1969, Jules Fisher, Article Casa Manana Theatre in Texas saw the invention and use of 12 PAR 64 lanterns, 120Watt, 12 Volt lamps equipped tilt, 360 degrees and 270 degrees, a standard that lasted util the 1990s. This lamp is also known as "Mac-Spot
At Bristol, in 1968 also made progress, particularly for use in live music. Peter Wynne Wilson refers to the use 1kw of profiles, with slides printed on the gobos included from a roll, like a slide projector. The boards also had a hood, a Multiple wheel stained gel. These fires were also made with mirrors and an impressive light show for Pink Floyd concert in London. Another light that Cycklops "was also known for the music used in the United States, although it was very limited in functionality with only panoramic and tilt functions and 1.2meter long and weighing 97 kg at least, including the ball, they were heavy and unwieldy.
In 1980, after the invention color filters Dichronic Jim Hurst was born in early 1980 to early Varilite Lyre became a reality, starting with the VL0, Genisis shown in summer. In addition, one of the first lighting consoles used with a numerical basis, allowing insight States Demo VL0 Genus in the center of an old barn to go to the program of compromise. Change the color and movement have been a corner of the room the other carried out the four steps of simple but impressive for all those who had not seen the technique before.
Genisis was more 55 years later by VLO1 in using their next string of appearances in the United Kingdom. The lights on the console was supplied with a LV-100 series, 32 channel, five 1802-processors and a dramatic improvement in the first tranche, which was very simple, has an external processor. The VL1 was also the first use of an XLR cable to a control application when DMX lighting has never been sent by him.
In 1985, the first head movement was made by Summa Technologies DMX protocol, which was rare at the time and was among many Others, including trainer DIN8, AMX, D54 and other protocols use companies such as Tasco, Varilite, High End, Coemar product. It looked even seen a device that would not look out of place in a theater. The Summa HTI 150W HTI had a lamp, 2 color wheels, a wheel, a mechanical drive and zoom functions. For the moment they had packed more features than any other in the front.
In 1987 began production of the first scanner ClayPacky recognizable, the analysis of gold. It uses stepper motors instead of servos and uses a 575 HMI Light, bright and with a uniform brightness of the beam. Tbis was followed by Intellabeam in 1989, also upscale, which were at that time, dealers Clay Paky and Belliveau realsed.
In the 1990s the future is closer to Martin, a Danish company, fog machines. They presented a number of scanners Roboscan experimented with a variety of different specifications for different users. Their line began with the 218, for the village and walked in brightness and, 518, 812, 918 and 1200Pro units. Martin has also invented a whole new set of head phones, including Mac250 Mac250 the + Mac300, MAC500, Mac600, Mac700, and now Mac1200 Mac2000 and MacIII. Martin Mac are very popular in most situations and rentals are also a good compromise between products made cheaper and fires top end as a High End DL2.
The future promises great things that the concept digital lighting, mounted a bright LCD or DLP projector a yoke or moving the head holder with built-in media server must take place for millions of colors to choose from, libraries endless gobos, image and video projections. The DL1 and DL2 of high-end systems (Barco) and Publitec Beamover.

An automatic fire, itself a lamp, light (or sometimes moving head) is a versatile and multi-functional design to replace more conventional, non-mobile sources of light. Depending on location and registration, automated lighting more versatile and economical to take stock of traditional lights, because when properly programmed, they can quickly change many aspects of their appearance, the change ersonality light very quickly. Lighting is usually pre-programmed and played with only simple commands, although ive heads mobile can be controlled if the operator has sufficient experience. Have

Control
moving lights are controlled in many ways. Usually, devices are at a lighting control console, an output signal. This control signal sends data to the device in general in one of three ways: analog (which expired in large part) DMX (which is the industry standard protocol control) or Ethernet control (This is still in development). The attachment is then this signal and converts it into internal signals that are on the stepper motor much of the interior.
XLR connectors, the most widely used to control the movement of heads. Note that these 3-pin XLR connectors that are used Some manufacturers, rather than the 5-pin, specified by the USITT DMX-512 standard.
The vast majority of moving lights can be devoted to the DMX protocol, usually using twisted pair, shielded cable with 5 pin XLR connectors on the ends. Each lamp is a block DMX channels in the location associated with the DMX universe (a closed set of cables and accessories the maximum of 512 individual channels can be used). The central panel light-transmitting data through these channels, who plays smart furniture that the parameters of the value (Horizontal swing) for all the many variables, including color, model, focus, lens, pan, tilt (vertical swing), speed, and animation.
Since achieving heads do not move to prominence DMX predecessor, analog, had passed the peak of its popularity, very few moving heads via analog input control (this is also due to crippling restrictions on bandwidth, data rates and the imprecision). Some of the most intelligent control devices for RJ-45 Ethernet cabling or transmission of data, because of the increased bandwidth available to the effects more complex. With the new Ethernet technology rudder are now in a position to a much wider range of automated control. Because many devices can be connected to a single network port RJ-45, these devices have the ability to listen not only to a control signal from a control panel for lighting, but have the ability to transmit information back to the control panel and other entities in the network. It is now possible for an attachment, the problem of self-diagnostics, announced in a network, or accept the setting changes from anywhere on the network, so that older versions obsolete system which had only one central brain, Table lighting control. Since RJ-45 (and similar technologies) use two-way digital communication capabilities bits Review allow lighting control networks for the safe operation of equipment, which people can certainly have an impact (Pyrotechnics, rigging mechanisms, etc.).
moving lights are programmed with a support in the box ETC light boards
lights phones are much harder to program than their analog cousins, because they have more attributes for each device to be controlled. A simple classic lamp uses only one control unit: intensity. Everything else should do the light is determined by human hands (color location, direction, etc.) and a light machine can have as many as 30 such channels. A number of products on the market so that operators and programmers easily control all of these channels over multiple facilities. lighting boards are still the mechanism control the most common, but many programmers are using software to do the job. The software is now available, provides an overview of rendering the output of the platform are produced calendars first, connected to the program or the console. This allows the programming on her show ever in the work of theater and know what to expect when the lights are connected to their controllers. These products generally have a little method to convert a computer's USB output to a DMX output.
The latest generation of mobile heads are integrated projection capabilities Digital Creation of a real convergence between lighting and video projection. This new generation of leaders require not only the intensity, position and focus control, but the demand for video content and control.
Construction
Intelligent lighting use generally compact arc lamps as light sources. Using servo motors or, more often, stepper motors connected internal mechanical devices and optics to manipulate the light before getting out of supporting the front lens. Examples of such devices are internal:
Mechanical shutter dimmer used to vary the intensity of light emitted. Mechanical drives are usually a specially designed hard drive or a mechanical shutter. Gates high speed stepper motors produce the stroboscopic effect.
Color wheels with dichroic color filters used, change the color bar.
Variable, progressive, cyan, magenta and yellow ink-jet filter mixing vary over subtractive color mixing. With this method , A much wider range of colors produced as its unique color filters.
Automated trains lenses are used to zoom and focus beam, irises be used to modify the beam size. Some faucets have not less than 10 independently controlled prisms and lenses to focus and shape of the Beam.
The gobo wheels with door and flaps to change the shape of the beam images or project. Some faucets have run the engine gobo into place to create, spiders use their effects, or complex lens systems to achieve the same effect.
automatic roller shutters framing another form of beam delivery and control reactions.
These lights, motors of the physical movement of the light beam to activate either:
Swivel mirror an automated system reflects the beam along the X and Y axes, or
Replacing the entire lens mount train motorized yoke with Pan & Tilt
Note that devices using the old method are not technically Oving heads, as the source of light is not stationary. However, the head term interchangeably in this article uses Oving.
Use

intelligent lights (commonly referred to as automated) can be used wherever necessary, for lighting high performance to be the likely evolution, rapid and extreme mood and effects. Lyres would be in a setting that is not a strong light (as unfit house) or if the quality needs of light provided does not vary too much (even if it may need to be very strong for a place like a stadium). Of course there are exceptions to this rule, including the use of a large number of heads for mobile international sporting events like the Commonwealth Games or Olympic Games, where thousands of automated devices often distinct advantage of the opening and Closing Ceremony of light. The 2008 Summer Olympics in Beijing, had a platform around 2300 smart devices is "the largest single automated lighting ever assembled for a single event "
Usually, however, use Intelligent lights theater, concerts and nightclubs, where the limits of the versatility of these devices can be used at its best. active and passive (although that these terms are not standardized): In these applications, the use of informal units can be divided into two categories.
The use Passive automatic lighting involves the use of his versatility to perform many tasks that would otherwise require to achieve by lighting Classic. For example, six to eight moving heads to create a textured blue impact of man on the ground, while using yellow light on the actors during a scene – which may create a feeling of dusk or at night. At the touch of a button you can change the device to create a animation red ire effect for the next scene. Need to try this transition, with traditional lights would not less than thirty instruments. In these circumstances, the automatic valves do nothing that could not be achieved with conventional bulbs are, but they drastically reduce the number of lights required for a platform. More Features of automated devices, such as rotating gobos are also possible with conventional devices are much easier to produce, but with intelligent devices.
A Martin MAC 250 Krypton (Profile – above) and MAC 250 Wash Wash) – see below).
The active use of fire automatic, which suggested that the light is used to perform tasks that otherwise would require human intervention and would therefore not easily with conventional equipment. For example, leading a number of moving production focuses closely, pure white, right down to the bar scene is a fantastic effect reminiscent of projectors produce from a helicopter before (especially when a fog machine or mist is used for the bars visible). To create such an effect, it would take at least one human being without intelligent lighting operator is directly above the stage with a tracker, are known generally as it would be too expensive for a small effect.
Mobile devices are often divided up in the head and wash lights. They vary in the uses and functions, but many companies offer versions of Profile and washing the same model of light. fires profile typically include functions such as gobos and prisms, lamps wash for simple optical and a wider opening angle continues, the effects internal lens or rust can be changed. Wash lights rather a mixture of CMY although it is common for high-end headlights on such characteristics to have. Spot units are generally for their jet-effect (usually through smoke or fog) and the ability to project texture, while the lights wash tend to provide a washing step to be used.
A Martin MAC 250 Krypton (Profile – above) and MAC 250 Wash Wash) – see below). Note the difference in radiation pattern caused by the gobo round and wider viewing angle of the wash.
Debate
Not all the lights, this movement can be defined as intelligent. Basic Club lighting is not controllable than others Fundamental and outside. This lack of features it does a small step on a stage lighting instrument classic.
movable mirrors are faster than enslaved mind. However, moving heads are visually interesting and have a much more movement. Motion lamps mirror quite simple, because the center of the movement for each axis is generally in the same place, while an axis of a light harp circle (Describing the rule "pan") and another ("tilt") changes the diameter of the circular motion. At the light at the beginning, a pseudo Gobo rotation effect could move in line with the inclination of the axis of others, and then reaches the pot from stop to stop.
