A device (10) has a carrier (11) and an optical element (12) supported by the carrier. The optical element has a macro-optical characteristic and at least one surface. A light shaping surface microstructure (14) is integral on the surface of the optical element. The microstructure homogenizes, shapes and controls directionality of light emanating from the surface of the optical element to produce a smooth, consistent and continuous pattern of light in a predetermined distribution shape and direction. The optical element can either transmit or reflect light incident on a portion of the device and the optical element.
Un dispositif (10) comprend un support (11) et un élément optique (12) porté par le support. L'élément optique a une caractéristique macrooptique et au moins une surface. Une microstructure de surface holographique (14) est solidaire de la surface de l'élément optique. La microstructure homogénéise, forme et agit sur l'orientation de la lumière émanant de la surface de l'élément optique de manière à produire une configuration de lumière douce, consistante et continue sous une forme et dans un sens de répartition prédéterminés. L'élément optique peut soit transmettre soit réfléchir l'incidence de la lumière sur une partie du dispositif et de l'élément optique.
