ABSTRACT:
The proposed device uses a plastic of any color with a cavity introduced in it and preferably with a polished inner surface, instead of a reflector or a light guide, to utilize increased reflection with grazing incidence (large angle of incidence versus the normal to the surface). The light from a light source is transported to the symbol by reflection in this cavity and on the inner surface. The light source is preferably of a flat structure.
