Introduction
1-5
Lampbank Test Fixture: An optional unit designed to test a single lampbank separately from the
display.
Lens/Reflector Assembly: Consists of reflectors, lenses and louvers. It is eight lenses high by 16
lenses wide. A lens/reflector assembly is easily removable for maintenance. Figure 6 illustrates
the front and back of a lens/reflector assembly. One lampbank mounts on the rear of this
assembly.
Light Detector: The light detector is a device that senses ambient light levels. The light detector
and the controller operate together to dim the display when maximum lamp brightness is not
required. This saves energy and extends lamp life. Refer to ED-9490 and Drawing A-79768 in
Appendix C for light detector installation information.
Louver: A piece of aluminum, 16 pixels long, positioned above each row of lamps to provide
contrast and help direct light.
Module: Consists of one 8x16
lampbank mounted to the back of a
lens assembly. A module, Figure 7,
is eight pixels high by 16 pixels wide.
One transformer can power one
module (128 lamps).
Multiple-Face Display: Consists of two or more
independent displays, as seen in Figure 8.
Pixel: In the case of a Starburst display, a pixel is the
smallest point on a display capable of producing red,
green, blue, or white light. On a Sunspot display, a pixel is
a single point of white light or a single lamp. A group of
pixels can arrange to form a letter, word or image.
