stage lighting instruments
DESCRIPTION
For use with a technical theater class. Stage lighting unit.TRANSCRIPT
Flood lights
Flood lights are lights that light a wide area. The light produced is considered a “soft” light and generally does not produce a harsh shadow.
Strip Lights
Strip Lights use standard light bulbs like the ones used in your home. Typically
150 watts max.
Strip Lights
Typically, gels are not used for color because the proximity of the lamp to the color would melt the gel. Therefore, Roundells are used.
Cyc Cells
Cyc Cells are much like strip lights. However, they use a much higher power lamp and can be used on
large stages.
Scoops Scoops use a reflector from 10” to 18” across to light a large area of the stage or backdrop.
They typically do not create high heat
temperatures and therefore can use Gels
for color.
PAR Cans
These rugged and efficient lamps, which
gained popularity in the concert field, are
typically used backstage for strong washes of down and back light.
Often called “Cans”
PAR Cans
PAR cans are the most inexpensive stage
lighting instruments.
They are often pre hung in banks of 12 to be
used in large numbers.
PAR Lamps
PAR lamps are identified by their diameters, in eighths of an inch; a
PAR64, therefore, is 8″ wide
PAR Lamps
Because pf their high efficiency, PAR lamps are also used as Aircraft Landing
Lights, (ACLs)
Spot lightsSpot lights (also known as Profiles) produce a narrower, more controllable beam of light than flood lights.
Spot lights can be “Focused” more precisely that flood lights.
Fresnel lenses were used in lighthouses to maximize the amount of light emitted. This diagram shows how a light source hits the lens, which has different shaped prisms to
refract the light and direct it forwards.
Profile Spot lightsProfile spotlights typically use a special reflector that uses an ellipsoidal shape to create a focused beam of light. Because of this spotlights are often referred to as ERS or Ellipsoidals.
Profile Spot lights
Using Shutters allow the operator to manipulate the shape of the light so that it does not appear in a circular shape.
Profile Spot lightsProfile spotlights allow for the use of Gobos to project patterns with the lighting instrument.
Profile Spot lightsIn order to accommodate for various throw distances, profile spotlights come with different lens tubes that create specific angles of beam spread.
