Appeal No. 1997-3280
Application No. 08/212,065
Appellants’ invention relates to a composite structure
including an electroluminescent light source with a
retroreflective sheet superimposed on the light source, and a
translucent or transparent fluorescent film superimposed
thereon. The fluorescent material can also be incorporated in
the retroreflective material and superimposed on the light
source. This composite provides both enhanced daytime and
nighttime visibility, even in the event of a failure of the
light source.
