designing the light of theaters and cinemas is now assisted by two auxiliary vital:
dynamic control systems using semiconductor devices and computers specially programmed to remember scene by scene and second to second.
the voluminous self-adjusting variable transformers, current limiting reactors and control systems of lights with magnetic amplifiers has desappeared behind the scenes.

From the console room you can watch images calibrated taking by several TV cameras, the director delivers lighting to the actors, and finally the target audienceis to reach quality to Public people.
But all is not so easy, The ultra-modern lighting systems equipped with electronic control modules and governed by computers. that is very expensive and learning using this systems is not achieved soon.

The control desk of the lighting system looks increasingly like the one used for the audio system, and even the knobs that regulate the levels in each fixture are identical to those used for adjusting the signals from microphones and other audio .
in addition to this board or control panel, a digital computer is installed which operates with a program specially written for this application to keep the settings available to all lamps used in the scene for each minutes of the show.

The most sophisticated systems used are the control modules of the lights, in addition to a range of light level sensors, which communicate with the control panel to achieve an optimal distribution of illumination.
By using the most advanced lighting technology not only saves energy but also reduces the heat generated in the area of the stage, and generally in theater, TV studio or cinema it feeds on demanding for HVAC equipment.
