lighting exam 1- all the questions and things

swap out the barrel

How to change the beam size of a Source 4 ERS?

adjust the lens distance from flood to spot

How to change the beam size of a Fresnel?

Change the lamp

How to change the beam size of a PAR64/PARcan?

change the lamp

How to change the beam size of a Source 4 PAR?

Your skin oil will make it explode

Why should you never touch a lamp?

Clean it with an alcohol wipe

What should you do if you touch a lamp?

Ellipsoidal Reflector Spot

What does ERS stand for?

adjustable barrel (go from hard to soft focus)

rotation knob (adjust barrel for shutter or gobo orientation)

interchangable barrels (for light size)

four shutters

gobo slot

accessory slot for iris/etc

very little waste bc all the parts are separate

Characteristics of Source 4 ERS

varying beam widths (moving lamp closer/further from lens affects beam size)

very soft light

can be shaped by barndoors, but still won't be a hard edge

no gobos allowed here

trad. fresnels use spherical reflectors

Characteristics of Fresnel

cheap

oval beam shape

light intensity and beam shape unique to the lamp within the PARcan

Characteristics of Par64 / PARcan

bunch of diff lenses

made with separate parts (very little waist)

Characteristics of Source 4 PAR

Light emitting diode

what does LED stand for

so many colors

doesnt get hot

theres like an LED version of everything now

long life

environmentally friendly

cheap!

Characteristics of an LED

the og stage light back when candles were a thing

alternating color filters, you can combo with them (not like an LED though. they fall short of my goat LEDs)

most commonly used to light backdrops/cycloramas, color wash

Characteristics of striplights

grouped in units of three (peas in a pod)

smooth even light distribution over a guess what. cyc. short for cyclorama

brighter than a striplight

placed 8-10 ft from cyc for even wash

Cyc light characteristics

all intelligent fixtures must be connected to DMX

mostly use arc lamps

all its fancy functions are controlled by the lighting console

four basic types: moving mirror, moving head, wash, and spot

moving lights characteristics

moving mirror, moving head, wash, and spot

four basic moving lights types

An electronic device that controls the intensity of an instrument

Define dimmer

It's like an address for the light for the designer to organize the light plot with. each light will have a diff channel etc

Define channel

name for the pipe the light is hung on

Define position

Each position starts at 1 and is numbered SL to SR, DS to US.

Define unit number

Where the light is focused

Define area or purpose

Company and number of the gel used for that instrument, R02

Define color

the type of instrument being used. 8" Fresnel, Source Four Par MFL, 26 degree ERS

Define type

Shows what the lights on the plot are like in symbols

Title like the one from scenic

Instrument Key, Legend, and Title Block

Shows what light goes to which channel

Channel hookup

AKA a magic sheet

Visual tool to see where each light is focused on stage

Lots of different ways that designers do this

Effects plot

Used by the light board operator, what its name is

Cue sheets

Reference sheet for specials

Groups list

Layout

Mark areas

Color and range of channel numbers

All specials needed

Schematic

Every outlet being used and the corresponding address, also scales showing where to hang the lights

Circuit plot

The lead lighting designer/technician

Who assigns the channel numbers?

You'll never believe this. The lead lighting designer/technician again.

Who assigns circuit/dimmer numbers?

Reference your schematic- it'll have your layout, colors, etc.

There's a diagram. You'll fill in all the places. That's a separate flashcard though so sit tight

How to fill in a light plot

purpose

what is "a" on this light plot example?

color

what is "b" on this light plot example?

unit number

what is "c" on this light plot example?

dimmer

what is "d" on this light plot example?

channel

what is "e" on this light plot example?

you see each light gets a different channel. lets say light A gets the channel 200. well that light can do a looot of stuff, so each thing the light can do will get a different channel. so 200 is like the starter umbrella channel, and all the different things that light can do will be numbers after 200 (like 201-214). the next light B will have a different starting channel number (not 201, because that is still the first light), it will be like. channel 215. so skipping all the things that light A can do and starting over. and then light B will have a lot of things it can do and will take the next few channels for its own purposes! gosh i hope this makes sense.

how does channeling work?

fresnel light

what kind of light is this?

cyc light

par64 / parcan

what kind of light is this?

source 4 par

what kind of light is this?

striplight

what kind of light is this?

follow spot

what kind of light is this?

just a narrow spotlight

usually consists of a movable, high power fixture mounted on a stand, with an operator

most use arc lamps

usually fitted with a manual iris, "dimmer", and a color filter changer

can be focused to have a hard or soft edge (like an ERS)

follow spot characteristics

moving light

what kind of light is this?

led light

what kind of light is this?

led light

what kind of light is this?

an ers (episoidal reflector spotlight)
