Problems solved by technology
Although glazing on the one hand allows for a consistent light effect, on the other hand it creates problems of adhesion and degradation of the enamel layer when it is on the outside and the enamel may prove to be incompatible with certain desired functions or Interfering, especially problematic for glazing units that include film

Embodiment Construction
[0096] exist figure 1 wherein the glazing unit according to the invention is a laminated glazing unit 1 comprising:
[0097] A first transparent plate 2, e.g. a rectangular plate (e.g. 300 mm x 300 mm area) made of mineral glass, has a first main face 3 and a second main face 4, and preferably rounded (to avoid peeling off) edges Face 5, for example Planilux with a thickness of eg 2.1 mm and a refractive index of 1.51 ® Plates of soda lime quartz glass (sold by Saint Gobain Glass).
[0098] A second glass pane 2', of the same composition and size as the first pane, or optionally with a lighter colored composition, provides a solar control function (for example, Venus glass sold by Saint Gobain Glass ® VG10 or TSA 4+ glass), and / or covered with a solar control coating, for example, with a refractive index of 1.51, with a main face 4' opposite face 4, and another main face 3' and an edge face 5' ;as well as
[0099] A polycarbonate plate 6 (having a refractive index of abou...

Abstract
The invention relates to a luminous glass panel which includes: at least two glass elements, in particular at least two transparent sheets of glass; optionally at least one lamination insert between the two glass elements; at least one waveguide element, on one surface of the lamination insert and / or between the two glass elements, said waveguide element having a refractive index higher than the refractive index of the adjacent insert and / or glass elements; at least one source of radiation, in particular positioned on the edge of the glass panel such as to illuminate the waveguide element viathe edge surface thereof; at least one means for extracting the radiation, consisting of at least one fibrous structure, said structure advantageously being in the form of at least one fabric, said structure or said extraction means being placed at the center of the waveguide element.
Description
[0001] This application is a divisional application of the PCT application "luminescent window glass unit" (application number: 201380036900.5, applicant: French Saint-Gobain Glass Factory) that entered the Chinese national phase on January 9, 2015. technical field [0002] The present invention relates to a lighted (or "illuminated") glazing unit primarily intended for use in architectural applications or any flat or area light applications, but which may also be used in automotive applications if desired. In particular, it concerns a glazing unit illuminated by its edge facet, in particular one illuminated using light-emitting diodes. Background technique [0003] Light-emitting diodes (LEDs) were originally used in flashing lights or as indicator lights for electronic and electrical devices, and have been used for many years as light sources in signaling devices (signal lights, etc.), indicator lights or position lights, hand lamps, or road lighting in automobiles, etc. ....
