Luminous glass panel

Abstract

The invention relates to a luminous glass panel, including: at least one substrate consisting of at least one preferably transparent glass element, in particular at least one transparent sheet; at least one radiation source; at least one means for extracting the radiation, said extraction means being arranged so as to create a luminous area, said extraction means consisting of at least one fibrous layer.

Description

technical field [0001] The present invention relates to illuminated (or "illuminated") glazing, more particularly luminescent glazing for vehicles, especially automotive glazing having light emitting diodes. The glass can also be used in buildings or any flat light or surface light application. Background technique [0002] Electroluminescent diodes or DELs (LEDs in English) were originally used to form lamps or indicator lights for electronic and electrical devices, and have ensured that automotive signal devices (signal lights, etc.), turn signals or position lights, lanterns or lamps have been used for many years. Target lighting. The advantages of diodes are their long life, luminous efficiency, reliability, low power consumption and compactness, making the equipment in which they are used more durable and necessarily resulting in reduced maintenance. [0003] Recently, electroluminescent diodes have been used in lighting glass for buildings or automobiles. In the lat...

Problems solved by technology

Although glazing results in a good uniformity of illumination, it in turn causes problems of adhesion and degradation of the enamel layer when it is on the outer surface, and the enamel layer may prove to be incompatible or interfere with certain sought-after functions, Especially problematic for coated glass, such as glass comprising a low-emissivity coating, often used in the automotive sector
