Abstract
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.
