Fixed luminous or illuminating device polarised from vertical for use as advertising sign or vehicle lighting

摘要

The device comprises screens which are linearly polarised, with axes projected orthogonally on the orthogonal plane, to the orthogonal projection on the optical axis. This connects the eye of an observer or a conductor, to the source light, in the terrestrial horizontal, orientated at 45 degrees to the vertical. Supports are arranged for the screens and for the internal illumination, or external non visible sources. The polarising screens may define a volume or surfaces, with opaque or reflecting planes, or developed polarised planes. The polarisation axes may be orientated at 45 degrees to right or left of the vertical, for surfaces of text letters, or illustrations, coloured or plain.
