Embodiment Construction

[0095] exist figure 1 wherein the glazing unit according to the invention is a laminated glazing unit 1 comprising:

[0096] 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).

[0097] 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

[0098] A polycarbonate plate 6 (having a refractive index of ab...

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 via the 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 centre of the waveguide element.

Description

technical field [0001] 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 [0002] 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. . Diodes have many advantages, namely their long lifetime, their luminous efficiency, their reliability, their low energy consumption and their small size, meaning that units employing them are more reliable and require less maintenance.
