Introduction 1-5
Lampbank: A circuit board consisting of an array of lamps 8 pixels high by 4 pixels wide. Figure 8
shows a single lampbank, front and back. Two lampbanks mount to the rear of each lens/reflector
assembly as seen in Figure 9. If necessary, a lampbank can be easily removed from the lens/reflector
assembly.
Lens/Reflector Assembly: Consists of reflectors, lenses and louvers. It is eight lenses high by eight
lenses wide. A lens/reflector assembly is easily removable for maintenance. Figure 10 illustrates the
front and back of a lens/reflector assembly. Two lampbanks mount on the rear of this assembly, as
seen in Figure 9.
Light Detector: An optional 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. Figure
11 shows the light detector for the Venus 1500 systems.
Louver: A piece of aluminum, eight pixels long, positioned above each row of
lamps to provide contrast and help direct light.
