Title (EN) LIGHT-EMITTING GLAZING UNIT WITH AN OPTICAL ISOLATOR
(FR) VITRAGE LUMINEUX AVEC ISOLATEUR OPTIQUE.
Abstract: front page image
(EN) The present invention relates to a light-emitting glazing unit (100) comprising: a glazing substrate (1); an additional element (1') that is tinted; an optical isolator (2) between the glazing substrate and the additional element; a light source (4) coupled optically to the glazing substrate; and light-extracting means (6) associated with the guiding glass. The optical isolator comprises a film, said to be of low index, based on a fluoropolymer, which: is of refractive index n2 at 550 nm such that n1 - n2 is at least 0.08; is of thickness e2 of at least 600 nm; makes optical contact with the first major face (11), which is referred to as the internal face, by way of a first lamination interlayer (7); and is based on a thermoplastic.
(FR) La présente invention porte sur vitrage lumineux (100) comportant : - un substrat verrier (1 ), - un élément additionnel (1 ') qui est teinté - un isolateur optique (2) entre le substrat verrier et l'élément additionnel, - une source de lumière (4), couplée optiquement au substrat verrier, - des moyens d'extraction de lumière (6) associés au verre de guidage, L'isolateur optique comprend un film, dit bas indice, en matière à base de fluoropolymère qui est : - d'indice de réfraction n2 à 550nm tel que n1 -n2 est d'au moins 0,08, - d'épaisseur e2 d'au moins 600nm, - en contact optique avec la première face principale (1 1 ), dite face interne, par l'intermédiaire d'un premier intercalaire de feuilletage (7), à base de matière thermoplastique.
