Abstract
A luminous glazing unit includes at least two glazing elements, for example at least two transparent glass sheets; optionally at least one lamination interlayer between the two glazing elements; at least one waveguide element, located on one face of the lamination interlayer and/or between the two glazing elements, the waveguide element having a refractive index higher than the refractive index of the adjacent interlayer and/or glazing elements; at least one light source, for example positioned at the edge of the glazing unit in order to illuminate the waveguide element via the edge face of the latter; and at least one light extraction device, formed by at least one fibrous structure, this structure being in the form of at least one textile, this structure or this extraction device being placed in the core of the waveguide element.
