  • Luminous glazing unit with optical isolator and manufacture thereof
    Patent number: 10252494
    Abstract: A luminous glazing unit includes a first glass substrate, made of mineral glass and in optical contact with a second glass substrate, a polymer layer, selected from a lamination interlayer, associated with a tinted and/or reflective element, and/or an opaque polymer encapsulation, a porous silica layer, underneath the polymer layer, a light source, optically coupled to the first glass substrate, and a light-extracting device associated with the first glass substrate, a mineral and transparent protective coating made of silica, directly on the porous silica layer and directly underneath the polymer layer.
    Type: Grant
    Filed: December 23, 2014
    Date of Patent: April 9, 2019
    Assignee: SAINT-GOBAIN GLASS FRANCE
    Inventors: Matthieu Berard, Brice Dubost, Stéphanie Morlens, Mauricette Rondet
  • Luminous glazing unit with optical isolator
    Patent number: 9612386
    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.
