Dimming

A dimmer is a accessory acclimated to alter the electrical adeptness delivered to the instrument’s lamp. As adeptness to the lamp decreases, the ablaze fades or dims. It is important to agenda that some blush change additionally occurs as a lamp is dimmed, acceptance for a bound bulk of blush ascendancy through the dimmer. Fades can be either UP or DOWN, that is accretion or abbreviating the intensity. Today, best dimmers are solid state, although abounding automatic dimmers still exist.20

Dimmers are generally begin in ample racks that draw ample amounts of three-phase electrical power. The dimmers themselves are generally disposable modules that ambit from a 20-ampere, 2.4-kilowatt assemblage to a 50-ampere or alike a 100-ampere unit. They can generally be replaced by a affiliated adeptness bore (CPM) which is basically a 20- or 50-ampere breaker in a concealment bore casing. Affiliated adeptness modules are acclimated to accumulation non-dimming accepted to added electrical accessories (like smoke machines, alternation winches, or breathtaking motors). Back a affiliated adeptness bore is installed, the agnate ambit is activated as continued as the concealment backpack is on, absolute of the lighting console. Failure to use a affiliated adeptness bore on a non-dimming accessory can aftereffect in the accident of the device, accurately back the accessory relies on an centralized agent that depends on a specific adeptness accepted (in the US, 110 V, 60 Hz power).21 Alike if a dimmer approach is trusted to consistently be operated at abounding power, during alpha up and shut bottomward cycles of a lighting ascendancy surface, baby amounts of babble arrest and DMX signal-recycling can account cursory interruptions in the abstracts beck and account a dimmer to dim a circuit, so a CPM is all-important to ensure that accessories is not damaged.

Increasingly, with the advance of agenda technology, avant-garde lighting instruments are accessible which acquiesce alien control, not aloof of intensity, but of direction, color, axle shape, projected image, axle bend and a abundance of added effects. The adeptness to move an apparatus anytime added bound and agilely has become the industry goal. Such automatic lights frequently accept congenital concealment and so are affiliated anon to the ascendancy cable or arrangement and are absolute of alien dimmers.
