Abstract
The lighting system comprises a transparent plate (3), and a light source (1) arranged immediately adjacent to a face of the transparent plate or incorporated into the latter. The plate has a pair of reflective or semi-reflective surfaces (6,8) on its opposite faces, according to a micro-telescope arrangement so as to generate an expanded light beam (9) with predetermined configuration and features going out of the surface of the plate which is remote w.r.t. the light source. Pref. the light source is a solid state source of the LED or laser type. The transparent plate is formed of a plastic or glass material and acts as transparent or coloured radiation guide whose transmittance curve is determined as a function of the spectrum emitted by the source. The reflective or semi-reflective surfaces may be constituted by portions of the opposite faces of the plate which are formed with micro-projections.
