Title (EN) LIGHT-GUIDE DEVICE WITH OPTICAL CUTOFF EDGE AND CORRESPONDING PRODUCTION METHODS
(FR) DISPOSITIF-GUIDE DE LUMIÈRE À BORD DE COUPURE OPTIQUE ET PROCÉDÉS DE FABRICATION CORRESPONDANTS
Abstract:
(EN) A light-guide device includes a light guiding element (13) with a number of faces, including two parallel faces (26), for guiding light by internal reflection. A transparent optical element (19) has an interface surface for attachment to a coupling surface (14) of the light guiding element, and is configured such that light propagating within the transparent optical element passes through the interface surface and the coupling surface (14) so as to propagate within the light guiding element (13). A non-transparent coating (15) is applied to at least part of one or more faces of the light guiding element (13), defining an edge (17) adjacent to, or overlapping, the coupling surface (14) of the light guiding element (13). A quantity of transparent adhesive is deployed between the coupling surface and the interface surface so as to form an optically transmissive interface. An overspill region 31 of the adhesive extends to, and overlaps, the edge (17).
(FR) Un dispositif-guide de lumière comprend un guide de lumière (13) ayant un certain nombre de faces, comprenant deux faces parallèles (26), pour guider la lumière par réflexion interne. Un élément optique transparent (19) présente une surface d'interface destinée à être fixée à une surface de couplage (14) du guide de lumière, et est configuré de telle sorte que la lumière se propageant à l'intérieur de l'élément optique transparent passe à travers la surface d'interface et la surface de couplage (14) de façon à se propager à l'intérieur du guide de lumière (13). Un revêtement non transparent (15) est appliqué sur au moins une partie d'une ou de plusieurs faces du guide de lumière (13), définissant un bord (17) adjacent ou chevauchant la surface de couplage (14) du guide de lumière (13). Une quantité d'adhésif transparent est déployée entre la surface de couplage et la surface d'interface de façon à former une interface optiquement transmissive. Une région de débordement 31 de l'adhésif s'étend vers, et chevauche, le bord (17).
