HP SPOT LUMINAIRE USER MANUAL
Lamp
Light source consisting of filament or electrodes, base, and envelope or "bulb."
Luminaire Calibration
The process of a luminaire finding its end stops for all parameters.
Macro
A pre-defined sequence that allows for quick and easy control of luminaire functions such as iris, zoom, framing, and
more.
Moiré Gobo
A gobo that has two pieces of glass wherein one is fixed and the other rotates. Since the two pieces of glass are very
close together, it creates an interesting interference effect (which is referred to as the "moiré").
Palette
Term for groups of groups; i.e. all the color groups would be considered the Color Palette, all the beam groups would
be the Beam Palette, etc.
Pan
The movement of the luminaire around the axis of the yoke.
Parameter
An individual controllable aspect of a luminaire: pan, tilt, color, etc. Also known as "Attribute."
Patch
The act of assigning a DMX512 channel to a control channel on a console.
Reply
Digital data signals transmitted from each luminaire to the console. Only one luminaire may transmit at a time, in
response to a request from the console.
Signal
Control protocol from a lighting console or interface.
Shutter
See
Framing.
Splitter (Isolator)
Device used to optically isolate and split a DMX512 signal.
Note: A DMX "two-fer" cannot be used to divide a signal.
Start
To energize a luminaire arc lamp (applies to arc-lamp luminaires only).
Strobe
A special lighting effect which produces multiple rapid bursts of high intensity light.
Terminate/Termination
Termination refers to the dampening of DMX signal at the end of the transmission line. Termination is created by
placing a 100 ohm resistor between pins 2 and 3 of the DMX line. Often, there is a switch on DMX devices to do this
internally. If not, a terminator is provided in the form of an XLR connector with the proper resistor between pins 2 and
3 to be placed in the DMX Thru port on the device.
Tilt
The movement of the luminaire around the axis of the tilt tube.
