Stage Electrics Final Review (2nd bi-term only)
Terms in this set (35)
A high-wattage instrument used for projecting large-format slides or moving images
A mirror that reflects a specifically selected wavelength of light and allows all others to pass through the mirror. A red one reflects red light and allows other wavelengths to pass through it.
Digital Micromirror Device (DMD)
An optical semiconductor whose surface is covered with hundreds of thousands of tiny micromirrors corresponding the number of pixels in the image display
the smallest "picture unit" in a digital image. The actual size varies with the size of the image, but pixels are extremely small relative to image size.
the unit measurement of light output
the output of a light source; measured in lumens
surrounding environmental light; light in the projection environment from sources other than the projector
The fineness of detail in a video image; as the number of pixels increases, more detail can be seen
the distance from the projector to the screen
the diagonal dimension of a screen
Rear Screen Projection
a projection technique; the projector is placed behind the screen and the image is projected onto, and through, a translucent screen
the projected video image
object on which light is falling
a point in time that marks the beginning or ending of an action. The intermediate action - the action between two keyframes - is filled in with frames referred to as "in-betweens." Used in traditional and computer animation.
the process of filling in the "in-between" images between two keyframes to give the appearance that the first image smoothly transitions into the second image. Accomplished with software programs in computer animation.
Refers to plays that rely on the spoken word to convey their message. Does not include musicals, reviews, dance, opera, or concerts.
in the context of lighting, primarily refers to touring rock and country shows
in the context of lighting, refers to night clubs in which high-energy music (live or recorded) is the prime attraction
to rotate horizontally
to rotate vertically
the term refers to all the fixtures used on a lighting design. Frequently shortened to "rig."
to connect one to another, in a continuous line, like a chain of daisies.
a fade profile is a linear, graphic representation of a fade. See the box "Fade Profiles" for further explanation.
Widening or narrowing of the cone of light emitted by the instrument
Specialty lenses mounted on a gobo wheel or an effects wheel. Used to divide the light into multiple beams, warp, or otherwise distort the fixture's beam of light.
A lens in which the surface or interior of the glass is scored or beveled to create the desired effect.
named for its shape. A roughly rectangularly shaped material - transparent, translucent, or opaque, depending on function - that is inserted into a beam of light to color, shape, or dim the light.
an electric motor whose movement consists of discrete angular steps (degrees of arc) rather than continuous rotation. Precision movement is achieved by programming the motor to run, in either direction, for a specific number of steps.
an electromechanical device in which a low-voltage circuit is used to control the opening and/or closing of contacts in a high-voltage on/off system.
a metal device used to draw heat away from heat-sensitive electronics and vent it to the air without the use of fans
a generated smoke effect that typically dissipates relatively quickly. If cooled, the fog will hug the ground.
a generated smoke effect that typically is longer lasting than a fog effect. Used to fill the entire stage house with a haze.
specialized liquid, normally composed of glycol and various additives, used in fog or haze generators to create fog and/or atmospheric haze effects
an engineered structure, usually made out of metal tubing, suspended above the stage or auditorium. Used as a hanging position for lighting equipment.
truss tower system
a truss supported on both ends by towers; used whenever quick setup and takedown is required; virtually eliminates fixture/pipe movement when working with moving light fixtures.
