Abstract:
Message display panel of the type comprising a plurality of light emitting elements arranged in matrix form on a display surface,wherein each light emitting element is constituted by a first end face of an oblong body made of a transparent material which comprises on its second end face at least one cylindrical housing in which a light emitting source is placed, said housing presenting a bottom having a convex internal surface so as to concentrate the light flow emitted by said source and illuminating said bottom into a narrower beam directed towards the first end face, said bodies being disposed in rows and columns and separated from one another, wherein the body presents a quadrangular section along a transverse plane, and the body further presents an annular swelling defined on each lateral face of the body by two planar surfaces which intersect in a transverse plane lying between the bottom and the first end face, said surfaces being intended to reflect at least a part of the light rays illuminating the cylindrical wall of a housing towards the first end face.
