Beam projector What is used to dim the light source inside a followspot? Douser Color light, all color is derived from light Hue The quality that differentiates one color from another Saturation refers to the amount of a particular hue in a color mixture Value relative lightness or darkness of a color Tint a color with a high value Shade a color with a low value Tone a color of middle value Primary colors Those hues that cannot be derived or blended from any other hues. What are the primary colors? red, blue, and green Subtractive color colored filters allow one thier own hue to pass through the filitering medium, all other wavelengths are absorbed Additive color Two different colored lights projected onto a neutral surface are interpreted to be a combination of those two colors. Gel (lighting) made from natural gelatin and colored with synthetic dyes it faded quickly, was fragile when dry and disintegrated when wet Plastic Color Media (Lighting) made fom mylar or pilester in a variety of colors, a rugged, long-lasting, heat-resistant product that is the current standard for stage lighting instruments. Glass (lighting) longest lasting of all media types but color choices are limited. it is expensive, heavy and breaks easily. most common from primary colors. Dichroics relfects other colors rather than absorb. What does a projection require? A projector, an image, and a projection surface What are the two categories of projectors? Those without lenses and those with lenses. What is an example of a lensless projector? Linneback Projector What are the three types of lens projectors?

Mechanical and Electronic What are the tree Mechanical dimmer systems? Saltwater, resistance, and autotransformer What are the two types of Electronic dimmers? Silicon Controlled rectifier dimmer (has no moving parts) and sine wave dimmer (newest) What are the four main categories of control consoles? group master, preset (set on cues), combination (part group master and preset), and computer memory Descirbe the Lighting System Electrical Flow Primary source enters the building > that servie branches out into different areas > from the dimmer rack, power then goes to the circuits around the stage > seperatae low voltage control signal runs between the control board and the dimmer rack > a lighitng instrucment is connected to the stage circuit and the control board tells the dimmer how bright to make the light. Black, white and green stand for what in cable color coding? hot, neutral, and ground The larger the number of the wire gauge, the __ of the wire. the smaller the diameter What is the most common cable in stage lighting? 12 gauge, 3 conductor (12/3) What is the ampage of a 12 gauge cable? 20 amps Plug the male connector Receptale the female connector What are the three types of cable connecting devices? twist lock, grounded pin, edison plug Feeder cable larger cable in individual pieces for supplying input to dimmer rack What are the four types of extension cables? multicable, fan out, two-fer, and adatper Circuiting the districution of electicity to all of the stage lighting positions in a theatre What are the four systems of distrubting circuits in a theater? permanent wiring, spidering, patch panel, and dimmer per circuit Name and describe the four types of patch panels Connecting strip - has an 18" pigtail every 12-18" with a connector at the end.drop boxes - small boxes containing 4 to 8 circuits ona larger cable that drops down from the grid to a pipe in the rigging stsmtefloor pockets are covered opening in the stage floor that contain 3 to 6 citcuitswall pockets - are boxes of 3 to 6 circuits mounted in or on a side wall of the stage, sometimes with no cover Semiconductor is a material that is normally an insulator but can be modified to confuct electricity. What is an example of a semiconductor? Silicon Diode The simplest type of semiconductor, allowing current to flow in one direction but not the other. How do LEDS differ from incandescent blubs? They do not have a filement Focal Length Distance from the lens it takes the light converge into a single point. Name and describe the four types of lenses Plano-convex lens - one flat face and once convex face; the greater the curature the shorter the focal length and the wider the beamDouble Plano-Convex lens Step lens - same characteristics at the plano-convex lens but the flat side is cut away into layersFresnel lens - varation of the step lens except the glass is cut away from the convex side not the flat side Name the two types of lamps Incandescent and Tungsten-Halogen lamp What are the three parts of a lamp Filament, Envelope and base Arc Source An electric arc between two electrodes What is the output of an incandescent lamp? just a measure of how bright the lamp The smaller the filment the ____ the output but ___ shorter the life greater, shorter Lumens measurement of the output of a lamp Footcandle measures the amount of light falling on a given area 1 footcandle = __ lumen 1 Angle of ____ = angle of reflection incidence Name and describe the four reflectors Spherical reflector - shaped like part of a sphere (used in fresenel)Ellipsodial Reflector - partial conical ellipse with two focal pointsParabolic reflector - shaped like a conical parabola (used in PAR)Comboination Reflector What are the two reflector materials Metal and glass AuthorAnonymous ID55833 Card SetStagecraft Final Descriptionstagecraft final Updated2010-12-14T06:00:40Z Show Answers
