1. A glazing, comprising:
- a first sheet comprising mineral or organic glass comprising a first main face, a second main face, and an edge;
a peripheral light source comprising an emitting face selected from the group consisting of an optical fiber and light emitting diodes that comprises a semiconductor chip on a support section of the diodes, the emitting face facing a side of the second main face, which is an injection side for a propagation of an injected visible and/or ultraviolet (UV) light into the thickness of the first sheet, which guides injected light;
a zone, which is made luminous by injected light or UV, formed bya surface diffusion extractor of the first and/or second main face, each of which extracts guided light via the first and/or the second main face, ora volume diffusion extractor in the first sheet, and/or a luminophore on the first and/or second main face, each of which converts injected UV light to visible light via the first and/or the second main face;
a fluid-tight cap, which covers the peripheral light source and is impermeable to liquid water or water vapor, wherein the fluid-tight cap essentially faces the second face, and is joined by a fastening element to the first sheet, and/or to a connecting part or element bound to the first sheet,wherein the cap is in contact with or integrated with an interfacial sealing element that is impermeable to liquid water or water vapor and comprises an inner face oriented toward the second main face; and
wherein, optionally, said glazing comprises a peripheral functional element bonded to the first sheet, which is a fluid-tight overmolding or a fluid-tight preassembled element.

Abstract
A luminous vehicle glazing containing: a first sheet having a first and a second main face; a peripheral light source, the emitting face facing an injection side, which is a side of the second face; a surface diffusion extractor, which extracts the guided light via the first and/or the second main face, or a volume diffusion extractor in the first sheet; a fluid-tight cap, which covers the peripheral light source and is impermeable to liquid water or water vapor, wherein the cap is a facial cap, faces the second face, joined by a fastening element, and associated with an interfacial sealing element.
