If you want to use intelligent lights in your venue, you should be aware of what are the possibilities of the moving heads and how exactly they function. Without any difference whether you are an user or an operator, knowing the rules of functioning of moving head fixtures should help you to get the best from your equipment.
There are several typical things for each kind of moving head.
Light source - moving head fixtures typically have arc lamps as their light source, though LED technology is used too. Because of this, a special energy supply is used, and the lights are not dimmable.
Dimming - in order to operate the intensity of the light output, moving heads need dimming or fading. Because this cannot be accomplished electrically, it is completed mechanically with specially designed for the goal shutters or discs.
Motion - among the largest benefits of moving head fixtures is their capacity to aim the lights in pretty much every single direction. This is doable with the assistance of servo or stepper motors, though the speed of motion isn't that fast.
Strobe shutter - a lot of LED moving head lights have an extra shutter for strobe control, which works on the on/off principle at a quite high speed.
Colours - an additional fantastic characteristic of the moving head lights. There are two varieties of color control - one color and color mixing. The one color control is made by one or more rotating wheels in the moving head. Unique dichroic filter systems produce the different colours. The color mixing control is attained with the assistance of CMY subtractive color mixing filter systems, in which the three basic colours Cyan, Magenta and Yellow are mixed with different intensity and produce range of colours.
Gobos - Gobos might be seen in any moving heads spot - a lot of of the fixtures include many built-in already inside, but a lot more might be custom-made and added if needed. Gobos are typically pieces of metal (though objects made from glass exist too), with holes cut into, making a particular texture of light. They could be of any form - abstract or subjects from the real world.
Prism, Focusing and other effects - Prism separates the light beam into three, five or a lot more images, with the possibility of rotating the latest. Focusing might be easy completed simply with a little effort from your working desk.
Summarizing, all talked about above functions and facts should be convincing enough for the value of the moving head lights for any disco cub or nightclub. Moving head fixtures add an extra pinch of spice to any lighting show, so every single prosperous club owner could count on them.
