Luminous laminated automotive glazing comprising inorganic light-emitting diodes and manufacture thereof

A luminous automotive glazing, said glazing comprising:

• a laminated glazing including a first transparent sheet of glass or plastic forming an interior glazing, a second transparent sheet of glass or plastic forming an exterior glazing and a lamination interlayer made of plastic located between the exterior and interior glazings
• the interior glazing having a main face that is oriented toward the lamination interlayer, first edge face and an interior main face,
• the exterior glazing having an exterior face, a second edge face on the side of the first edge face and a main face that is oriented toward the lamination interlayer,
• under a peripheral edge of said main face of the exterior glazing, a plurality of inorganic light-emitting diodes that are spaced apart from one another and that each include an emitting surface that is located facing said first edge face, the plurality of inorganic light-emitting diodes being in a common recess of the first edge face,
• the plurality of inorganic light-emitting diodes being on a front main face of a diode carrier, the front main face of the diode carrier provided with conductive circuits that supply the plurality of inorganic light-emitting diodes, the front main face of the diode carrier including bearing zones that bear the plurality of inorganic light-emitting diodes, the diode carrier having a fastening portion that is adhesively bonded to a peripheral edge of the interior main face of the interior glazing by an adhesive,
• a profiled bead, including:
• an exterior lip on said peripheral edge of said main face of said exterior glazing or said second edge face, or both,
• an interior lip on the peripheral edge of said interior main face of the interior glazing, said interior lip not lying against said first edge face
• a body that is located between said exterior lip and said interior lip, said body being located a distance away from said emitting surface of the light-emitting diodes, and furthermore being located a distance away from said first edge face, the emitting surfaces of the diodes making contact with or being spaced apart by air and by at most 1 mm from said first edge face,
• a protective adhesive strip, including a base and at least one front main adhesive face, with a first end adhesively bonded to a peripheral edge or to a border of the main face of the interior glazing and a second end adhesively bonded toward the interior main face of the interior glazing, the protective adhesive strip forming a seal-tight barrier between the profiled bead and the plurality of inorganic light-emitting diodes, and between the profiled bead and the first edge face, the front main adhesive face being on a back main face of the diode carrier,
• wherein the plurality of inorganic light-emitting diodes are configured to emit one or more visible light rays that are guided in the interior glazing, before light extraction with a light-extracting system, the visible light rays being visible from a side of the interior main face of the interior glazing, or are configured to emit one or more ultraviolet light rays that are guided in the interior glazing, before conversion into visible light and light extraction, the light rays being visible from a side of the interior main face of the interior glazing, the light-extracting system being within the interior glazing or on main face of the interior glazing or on the interior main face of the interior glazing.
