Lighting chain, fixtures and controlLE

stage lighting fixtures- LED washes, batons, ETC source, filter gels-different thickness, conventional fixtures or generic fixtures have shutters (four points)- used for when you need a sharp edge ie 90 degree angle. high intensity.”fixed focal length” shorter the tunnel the wider the beam and the longer the tunnel- the narrower the beam- beam angles.

gobo’s- normally metal (light continuously shining through).

source 4 zoom- adjustable tunnel

Fresnel lens spotlight- lighter and smaller than the source 4. allows you to move the lamp. the beam can be shaped but external barn doors but cannot be cut sharply buy ERSes. (no shutters) cannot use gobo’s. they are useful for a sort edge and ability to have variable beam angles

parabolic aluminized reflector- traditional PAR fixture is self contained. you cannot adjust the beam angle unless you buy the specific lamp for the fixture. very narrow spot (VNSP) narrow spot (NSP) medium flood (MFL) wide flood (WFL).

ETC manufacturer- Altman

LED fixtures .- stands for light emitting diode

follow spots. needs somebody to stand behind them and operate them to light up a performer. the follow spot will have an iris for controlling the size of the beam. a dowser which is a mechanical dimmer which can control the intensity beam and to fade in and and fade on the light. must be more powerful the any other light on stage.

boomerang -changes the colour of the beam.

automated fixtures- its automatic and programmable. moving head or moving yoke, these work by moving the entire body. more likely to have a tight beam. mortised focus. a moving head spot has a built in gobo.








Could we re-structure these notes to make a bit more sense please? - EH081214
