Illuminable laminated glazing for a vehicle and vehicle comprising such a glazing

A laminated glazing for a vehicle, comprising:

• a first transparent sheet, made of mineral glass, with a first main outer face and a second main inner face,
• a second transparent sheet, made of mineral or organic glass, with a third main face and a fourth main face called face, which second transparent sheet has a refractive index n0 in the visible range,
• between the second main inner face and the third main face, one or more dielectric, transparent intermediate layers with given refractive indices in the visible range, comprising a polymer lamination interlayer,
• the first transparent sheet being tinted and/or a first layer of the one or more dielectric transparent intermediate layers being tinted,
• wherein when several intermediate layers are tinted, the first tinted layer is the tinted layer closest to the third main face,
• n2 being the lowest refractive index among the refractive indices of the intermediate layers between the third main face and up to and including the first tinted layer, or up to the second main inner face in the absence of a tinted intermediate layer, with n2<n0,
• means for extracting guided light in the second transparent sheet,
• on the fourth main face, a transparent, dielectric, optical protection layer with refractive index n1 in the visible range with n1<n2 and thickness E1 of at least 100 nm and submillimeter.
