L
LIGHTING STATE
The format of lighting used at a particular point in the production; a
lighting "picture". A lighting cue is given by the stage manager which
initiates the change from one lighting state to the next.
LIGHTING STENCIL
Plastic stencil containing a range of scale symbols for current lighting
equipment. Greatly facilitates the drawing of lighting plans.
LIGHTJOCKEY
Club / DJ control and visualization software by Martin.
LIMELIGHT
An obsolete source of intensely bright light, most recently used in
followspots.Derived from a burning jet of oxygen and hydrogen impinging on a
rotatable cylinder of lime.
LIMES
Followspots and their operators. This term is still in everyday use,
although limelight is not.
LINNEBACH PROJECTOR
Optically simple lensless system for projecting a shape from a gel or glass
slide etc. onto a set or cloth. The slide is placed in the front runners of
the projector which is a floodlight (with a point source lamp, and no
reflector). Often used for shadow effects or simple scenic projection. The
projector was developed in Germany by Adolphe Linnebach (1876-1963) in 1916
at the Court Theater, Dresden. In order to get a sharp image, the lamp
filament should be as small and as bright as possible, with adjustment to
move it towards and away from the slide. A high intensity low voltage lamp
is often used for this purpose.
LOAD
1) The electrical power rating, in Watts, of the equipment connected to a
particular lighting dimmer. 2) The equipment connected to a dimmer.
LOBSTERSCOPE
A mechanical device that reproduces the flashing "motion-freezing" effect of
a strobe.
LOW SMOKE
Smoke that has been chilled as soon as it comes out of the smoke machine.
This causes the smoke to lay close to the floor. Use fast dispersing smoke
for this effect because when the smoke heats up in the air, it will rise.
Low Smoke is much safer to work with than DRY ICE, which produces a
longer-lasting effect but is more expensive.
LOW VOLTAGE
Lower voltage lamps give more intense light than mains voltage lamps of the
same wattage.
