  • OPTICAL SCREEN FOR DIRECTING LIGHT BEAMS WITH ELEMENTS HAVING AN OPTIMIZED GEOMETRY
    Publication number: 20100309669
    Abstract: The present invention relates to an optical screen for directing light beams comprising a substrate (11) having a first surface (13) particularly for the inlet of light beams (30) and a second surface (12) particularly for the emission of light beams (30), at least one of the surfaces (12, 13) of the substrate (11) being provided with a plurality of protuberances (14) which extend in a direction perpendicular to the substrate (11) and characterized in that the protuberances (14) consist of revolution solids around an axis (A) whose generatrix is defined by at least a first curvilinear section (16) with a concavity facing the inside of the protuberance (14).
