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.

Luminous glazing unit

The invention relates to an electrochemical device () having electrically controllable optical and/or energy transmission properties, of the type comprising two electrode coatings () and, between them, an electrochemically active layer () made of an inorganic material capable of reversibly switching between two states having different optical and/or energy transmission properties by the insertion and extraction of ions. An electrolyte () is present between the electrochemically active layer and the second electrode coating. The material of the electrochemically active layer is a material, the insertion and extraction of the ions of which during switching between the two states correspond to a variation in the plasma wavelength &#x3bb; of the material and in that the material has, at the plasma wavelength &#x3bb;, a full width at half maximum &#x394;&#x3bb; of the absorption spectrum equal to or less than 1 micron in the two states.

Electrochemical device having electrically controllable optical and/or energy transmission properties

A luminous glazing unit including at least one substrate formed by a transparent glazing element; at least one light source; and at least one light extraction device for extracting the light, the extraction device being arranged to create a luminous region, the extraction device being formed by at least one fibrous layer.

A radiation-collecting device includes at least one radiation-collecting element and a scattering layer placed, in relation to the element, on that side on which the radiation is incident on the device. The scattering layer has a transparent fibrous structure and a transparent medium for encapsulating the fibers of the fibrous structure, the absolute value of the difference between the refractive index of the fibers of the fibrous structure and the refractive index of the encapsulating medium being equal to or greater than 0.05.
