Abstract

The device (10) has a flat transversal light guiding sheet (12) including an angular sector around a point light source e.g. side-emitter type LED, axis (S). The sector forms an elementary portion of an outer return edge (18), where the portion is conformed in a manner so that a meridian propagation plane (M) of a light ray reaching the portion is perpendicular to points at the portion. The portion is inclined in a manner so that the ray is totally reflected in a direction of a longitudinal optical orientation axis by traversing light ray guiding surfaces (14, 16) to form a linear light beam.
