초록 ▼

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.

대표청구항 ▼

[ What is claimed is:] [1.] An edge-lit light box sign assembly comprising;a plastic housing having at least one semi-circular linear concave surface having a depth, a highly reflective plastic film lined thereon, a flange extending in all directions to provide an enlarged area, and an extended clear plastic panel seated on said flange for use as a writing board, said flange having at least one end thereof being bent in a right angle towards the back thereof to define a bent section, said bent section having the same length as the depth of said linear semicircular concave section to provide a supporting leg for stable mounting of said edge-lit light box sign on any plane surface; andsaid clear plastic panel has a surface area slightly smaller than the surface area of said enlarged area of said extended flange, whereon any message or artistic graphics may be drawn by using wet erasable water base fluorescent markers, said clear plastic panel having at least one end portion being bent along a predetermined line parallel to a free edge straight line of said panel at a predetermined angle so that the edge line of the bent portion is facing towards the center of a light source positioned within the concave section, and a maximum light energy may enter into a edge face of the bent portion of said clear plastic panel, being seated on said extended flange area by fastening means;a sign face plastic panel having graphic art provided on the surface thereof and being held and slidingly movable on holding means, and said sign face plastic panel covers an opening area defined by said clear plastic panel which allow one of direct and diffusive passing of light energy emitted from said light source to observers therethrough; andsaid light source comprising at least one tubular lighting means positionally located adjacent to a bottom of said highly reflective semicircular concave surface for each one of said semicircular concave surface for each one of said semicircular and linear reflective surface.
