3rd 6 Weeks Vocab
Intro
Circuit = Established path or conduit of electricity.
Optics = Manner of manipulating light after it leaves the source.
Modeling = the revealing of form of an object through the pattern of highlight and shadow.
Batten = Horizontal pipe on which lighting instruments or scenery can be hung.
Hang = To secure a lighting instrument to a grid or batten in the theater.
1 History / Electricity
Volt = The measurement of the potential energy for an electric field. Voltage causes an electric current in an electrical conductor.
Ampere / Amp = A unit of electric current, or amount of electric charge per second.
Current = The flow (movement) of electrons within an electric field.
Resistance = The degree to which an object opposes an electric current moving through it.
Potential = The energy difference between two points of a non-moving electric field.
2 Color
Intensity = The level of brightness of a light.
Distribution = The direction, shape and size or quality (diffuse or clear)
Movement = The timed change in light level or the physical movement of light sources.
Filter = A material that allows certain frequencies of light to pass through, while preventing the passage of others.
Primary = A fundamental color that cannot be made by mixing any other two colors. All other colors are mixed from primary colors.
3 Instruments
Wash = Lighting source which illuminate broad areas of the stage (not specific).
Lamp = The name of what is often called a light bulb.
Lens = Used to redirect the spreading rays of light coming from the source to the reflector.
Practical = A light onstage that is the actual source.
Focus = The adjustment of the size or shape of a light beam.
4 Board
Cue = One specific lighting look and its fade time.
Channel = A lighting control path. The virtual control of dimmers.
Patch = The assignment of circuits to dimmers.
Black out = Instantaneous dousing of all stage lights.
Preset = Setting the controls of an apparatus prior to use.
5 Documentation
Grid = A collection of beams that provide a working platform above the stage floor.
Light Plot = Blueprint of where lighting instruments are hung and circuited.
Key = Accent or highlight on the actor’s face, usually from the direction of the motivating light for the scene.
Fill = Wash or soft light that fills in the light on the face from the directionopposite the key light.
Dimmer = Apparatus for regulating the flow of electric current causing a light to be more or less bright.
