ABSTRACT:
An improved illuminated sign comprising a thermoformed plastic housing having at least one linear semicircular inner surface lined by highly reflective plastic sheet material and clear plastic sheet having a bit smaller dimension of cut off opening area whereby a sign face is covered to pass light energy emitted from light source positionally enclosed in the plastic housing. The clear plastic panel is extended to form any geometric or irregular free edge line which cut face is bevelled to create a geometric or an irregular illuminated edge line that can be observed as a boarder line surrounding the sign graphics from the observers from the front side of the sign. An extended length of the clear plastic panel may be used as a wet erasable writing surface by using water base fluorescent markers which is useful to show a strong sign together with hand written messages or graphics surrounded by a illuminated boarder line on one fixture.
