Abstract

La présente invention concerne un guide de lumière multizone (100) pour habitacle de véhicule. Le guide de lumière multizone (100) diffuse une lumière d'ambiance provenant d'une source de lumière (900) dans un habitacle de véhicule à travers une pluralité de zones lumineuse. Ce guide de lumière multizone (100) comprend un ensemble de fibres optiques (101), ledit ensemble de fibres optiques (101) définissant au moins deux portions lumineuses tissées (110) et au moins une portion de liaison (120) disposée entre les au moins deux portions lumineuses tissées (110). L'ensemble de fibres optiques (101) est alternativement sur sa longueur libre de sorte à former la portion de liaison (120) et tissé de sorte à former les portions lumineuses tissées (110) séparées par la portion de liaison (120). Ces portions lumineuses tissées (110) diffusent la lumière provenant de la source de lumière (900). La portion de liaison (120) confine cette lumière provenant de la portion lumineuse tissée (110) vers l'autre portion lumineuse tissée (110).The present invention relates to a multi-zone light guide (100) for a vehicle interior. The multi-zone light guide (100) diffuses ambient light from a light source (900) in a vehicle interior through a plurality of light zones. This multizone light guide (100) comprises an assembly of optical fibers (101), said assembly of optical fibers (101) defining at least two woven light portions (110) and at least one connecting portion (120) disposed between the at least one. at least two woven light portions (110). The set of optical fibers (101) is alternately over its free length so as to form the connecting portion (120) and woven so as to form the woven light portions (110) separated by the connecting portion (120). These woven light portions (110) scatter light from the light source (900). The connecting portion (120) confines this light coming from the woven luminous portion (110) to the other woven luminous portion (110).
