Dimmer - Dimmers are devices used to vary the voltage running to a light. By decreasing or increasing the voltage to the lamp it is possible to vary the intensity of the lamp. Changes in intensity are called “. Used . fades” and can be “fade ups” or “fade downs.” Although variable-voltage devices are used for various purposes, the term dimmer is generally associated with lighting control. Small dimmers are. Used . seen more and more in the home. These have traditionally been actuated by direct control. The advent of X-10 technology is making remote control of home dimmers possible. A digital signal is imposed on the ho...

Joule - A term in the international system for a unit of electrical, mechanical, and thermal energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for one second. Used . . Surge protectors are often given joule ratings, but this rating refers only to the amount of energy they can absorb, not what gets through. Its value was calculated originally by James Pr. Used . escott Joule, but the term was first introduced by Dr. Mayer of Heilbronn....

Lighting Desk - Lighting control consoles (also called lighting boards or lighting desks) are electronic devices used in theatrical lighting design to control multiple lights at once. They are used throughout the ent. Used . ertainment industry and are normally placed at the FOH position or in a control booth.

All lighting control consoles can control dimmers which, in turn, control the brightness of. Used . the lights. Many modern consoles can also control intelligent lights (lights that can move and change colors), fog machines and hazers, and other special effects devices.

Consoles communicate wit...

Subtractive Color - Subtractive color explains the theory of mixing paints, dyes, inks, and natural colorants to create colors which absorb some wavelengths of light and reflect others. The color that an object appears t. Used . o have is based on what parts of the electromagnetic spectrum are reflected by it, or conversely by what parts of the spectrum are not absorbed.

Anything that is not additive col. Used . or is subtractive color. No other color mixing systems are known, except the imperfect system resulting from mixing real pigments, something that is very confusing nowadays.

Fresnel - Fresnels are typically 8-, 6- or 4-inch, referring to the diameter of the lens. This light is named after Augustin-Jean Fresnel who invented the distinctive Fresnel lens which has a 'stepped' appearan. Used . ce instead of the 'full' or 'smooth' appearance of other lenses. The stepped nature of the lens causes a corresponding pattern of circles of light, so Fresnel lenses are usually 'stippled' on. Used . the flat side. This pattern of small bumps helps to break up the light passing into the lens to smooth out its eventual pattern.

Fresnels use a spherical reflector, with the filament of the bulb ...
