-
what are the properties of light
- intensity
- color
- movement
- distribution (like angle, focus, hard/soft edge, etc)
-
circuits
- 2 types;
- Parallel- a bunch of wires connecting the lights
- Series- one wire connecting the lights
-
Ellipsoidals
- also called Source four or ERS
- long ones with shutters
- has several lenses
- gobo can be used
- mounted far away from stage
-
Scoop
- soft light
- no lenses
- colored gel
- mounted close to stage
- floodlight
- used to cover the stage in blue
-
Fresnel
- mounted close to stage
- short and square
- 1 lense
- soft light
-
Dimmer
controls the amount of electricity sent out
-
circuit (in a lighting system)
- pathway for electricity to flow
- outlet in the wall
- number that you plug the light into
-
channel
- how the lightboard talks to the system
- controls the dimmer
-
Standard Voltage
120 volts
-
W=VA
- W is watts
- V is volts
- A is amps
- W= 120 * amps
-
1. Cable
2. Jumper
3. 2 -fer
- 1. extention cord
- 2. cord that is 5 feet or less
- 3. lets you plug 2 instruments into one
-
McCandless Method
- theory of lighting plots to recreate 3:00pm
- 45° angles
- warm and cool lights
- Key light- brighter light, main source
- Fill light- filling in the shadows, lower light
-
3 primary colors of light
- red
- blue
- green
- these 3 together create white light
-
-
amps
flow of electricity or power
-
dimmer capacity
how much wattage you are able to have on the dimmer
-
volts
potential power and pressure
-
intensity
how bright something is
-
dimmer load
how much wattage you actually have on the dimmer
-
Gobo
- light pattern that you insert into an ERS
- it is a type of "color media"
-
gel
- colored plastic
- this is a type of "color media"
-
types of connectors used
- 20 amp stage pin (the square kind we use in Belk, 3 prongs)
- 20 amp twist lock (round kind with 3 prongs)
- 15 amp edison (normal plug)
-
Wires
- ground wire is green
- Neutral wire is white
- hot wire is black
-
soft and hard patching
- soft patching- do it on the light board with the computer
- hard patching- physically plug the lights in
-
Alternating current
Direct current
- electricity used with batteries
- electricity from the wall
