on a surface expressed in
lumens.
illuminated awning:
An awning sign that is lit
from underneath by fluorescent

The light shines through
the awning fabric illuminating

nighttime readability. The
light emanating from underneath
the awning also provides

A sign where the sign face
is illuminated in some manner.
(Also called backlit sign.
See also internally illuminated

A lamp that contains a wire
filament (typically made
of tungsten) that produces
visible light when heated
by an electric current to
the point of glowing.

Typically smaller in size,
examples of incidental signs
