If you want to use intelligent lights in the nightclub, you have to be mindful of what are the possibilities of the moving heads and how exactly they function. No matter whether you are person or an operator, knowing the principles of work of moving head fixtures will assist you to get the best out of the devices.
There exist various common things for each and every class of moving head.
Lighting source - moving head fixtures commonly have arc lamps as their lighting source, though LED lamps are used too. Due to this, a special energy supply is used, and the lights are not dimmable.
Dimming - in order to operate the intensity of the lighting output, moving heads need dimming or fading. Because this can’t be done electrically, it is completed mechanically with specifically developed for the function shutters or discs.
Motion - one of the biggest positive aspects of moving head fixtures is their potential to aim the lights in almost each and every direction. This is achievable with the help of servo or stepper motors, though the velocity of movement isn’t that quick.
Strobe shutter - most moving head lights have an extra shutter for strobe management, that works on the on/off principle at a quite high velocity.
Colors - one more wonderful function of the moving head lights. There exist two kinds of color management - fixed color and color mixing. The one color control is produced by one or more spinning wheels inside the moving head. Special dichroic filter systems create the distinct colours. The color mixing management is attained with the help of CMY subtractive color mixing filter systems, in which the three general colours Cyan, Magenta and Yellow are combined with distinct intensity and create wide variety of colours.
Gobos - Gobos may be found in any moving heads spot - most of the fixtures come with quite a few built-in by default inside, but much more may be custom-made and added if needed. Gobos are normally items of steel (though products produced from glass exist as well), with holes cut into, producing a particular pattern of light. They may be of any kind - abstract or subjects from the real world.
Prism, Focusing and other effects - Prism separates the light beam into three, 5 or much more images, with the possibility of spinning the latest. Focusing may be easy completed simply with a small effort from the working desk.
Summarizing, all mentioned above functions and details have to be convincing enough for the significance of the moving head lights for any disco or nightclub. Moving head fixtures add an extra pinch of spice to any lighting show, so each and every successful producer should count on them.
