Abstract
Official abstract text for this publication.
A luminous glazing unit includes a glass substrate, an additional element that is tinted an optical isolator between the glass substrate and the additional element, a light source, optically coupled to the glass substrate, and a light-extracting device associated with the glass substrate. The optical isolator includes a low-index film, made of fluoropolymer-based material which: has a refractive index n2 at 550 nm such that n1-n2 is at least 0.08, has a thickness e2 of at least 600 nm, is in optical contact with the first main face by a first lamination interlayer, based on a thermoplastic material.
First claim
Opening claim text (preview).
1 . A luminous glazing unit comprising: a first glass substrate, made of mineral glass having a refractive index n1 of less than 1.6 at 550 nm, with first and second main faces and an edge face, and in optical contact with the first main face: an additional element which is tinted, scattering, or reflective, an optical isolator inserted between the first glass substrate and the additional element, the optical isolator having a refractive index of less than n1 at 550 nm, a light source, o…
