Embodiment Construction

[0175] For clarity of illustration, the various object components have not necessarily been shown to scale.

[0176] figure 1 A cross-sectional and partially schematic view of a lighted glazing of a motor vehicle 100 in a first embodiment of the invention is shown.

[0177] exist figure 1 Among them, the glazing according to the invention comprises a glazing module having edge faces and main outer surfaces named Surface A and Surface B, said glazing comprising:

[0178] - a first glazing 1, e.g. rectangular (e.g. with dimensions 300 x 300 mm), made of inorganic glass, with a first main surface 11 and a second main surface 12 corresponding to the surface A, and preferably with rounded corners (to avoid flaking ) edge face 10 cut here longitudinally (or transversely in variants) for example of an ultra-transparent soda-lime-silica glass layer, such as Diamant glass sold by the company Saint-Gobain Glass, with a thickness equal to, for example, 2.1 mm and a glass window with a ...

Abstract

The invention provides a luminous window (100) for a motor vehicle, comprising: - a first window (1), made of inorganic or organic glass, having a first and second main surface (11, 12) with a refractive index n1 is at least 1.4, - a light source (4) coupled to the first glazing, - light extraction means with a diffusion layer having a width of at least 1 cm, the diffusion layer has diffusion dielectric particles (51) and a transparent matrix with a refractive index n2 (5) bonding. Most of the diffusing particles are particles separated from each other and a transparent shell comprising a dielectric material, and in contact with a transparent matrix, the core surrounded by the shell has a refractive index n3 greater than 1.15 and a larger size, D3, in the range of 5 μm to 200 μm , the particles have less than 2D 3 larger size.

Description

technical field [0001] This invention relates to light emitting (or "flashing") motor vehicle glazing, and more particularly to motor vehicle glazing using electroluminescent diodes. Background technique [0002] For many years, electroluminescent diodes or DELs (LEDs in English) have been used in motor vehicles as signaling devices (signal lights...), turn signals or side lights. The advantages of diodes are their long service life, light efficiency, robustness, low energy consumption and compact size, so that equipment can use them for a long time and require only low maintenance. [0003] In recent years, electroluminescent diodes have been used for vehicle headliners, in particular a panoramic laminated roof illuminated by photoluminescent diodes as described in document WO2010049638. Light emitted by the diode is introduced by forming an edge face on the inner pane of the glazing, and the light is extracted from the glazing by a diffusing layer on the glazing, such as ...
