The module contains a light emitting flat panel constructed of plastic optical fibers which convey the light from a
separately located light source. The panel is heat free, has indefinitely long life and has good brightness
uniformity. The optical fibers are gathered into a bundle at the end of the flat panel and are routed to the light
source.
The separately located light source is affixed to a bracket that mounts behind the display module using two of
the module mounting holes (see the outline drawing, Figure 20). If the increased module depth is not
acceptable, light source can be relocated elsewhere by the user within an approximate 2.5 inch radius (length
of the fiber bundle) from the end of the display module. The standard light source is a halogen 5.0 Volt, 4.85
Watt lamp with 8.0 inch leads terminated by a connector to be connected by the user.
Care should be exercised in the physical location of the light source since halogen lamps operate in excess of
250 C.
Because the attenuation of the LCD cell, only 10% of the backlight luminance is emitted from the display. Thus
to provide a brightly lit display, the original light source must be 10 times brighter.

The standard light source is a 4.85 Watt, 5.0 Volt halogen lamp. Figure 19 below shows the standard light
source and two alternates which use less power. They may be satisfactory for a display in low to no ambient
light and are available by special order.
These sources all include a reflector as part of the lamp, which focuses the light toward the polished end of the
fiber bundle.

The lamp may be powered by either AC or DC voltage. The 8.0” lamp leads are terminated in a Molex
connector P/N 50–57–9402. This mates with numerous Molex headers including the following:
