1. A luminous laminated glazed roof for a vehicle, said roof comprising:
- a laminated glazing including;
a first transparent glazing, made of mineral glass, with first and second main faces, which first transparent glazing is intended to be an exterior glazing;
a second transparent glazing made of mineral glass, with third and fourth main faces, which second transparent glazing is intended to be an interior glazing;
between the second and third main faces, which are internal faces of the laminated glazing, a transparent lamination interlayer film made of thermoplastic polymeric material, the lamination interlayer film having a fifth main face oriented toward the second main face and a sixth main face oriented toward the third main face; and
at least one inorganic light-emitting diode, each inorganic light-emitting diode including at least one semiconductor chip, each inorganic light-emitting diode being able to emit in a direction of the third main face;
wherein said lamination interlayer is provided, between the fifth main face and the sixth main face, with one or more apertures that are through apertures or that form blind holes, each inorganic light-emitting diode being of sub-millimeter-sized thickness and being housed in a through aperture or a blind hole;
wherein each inorganic light-emitting diode is associated with a through aperture or a blind hole encircling the edge face of the inorganic light-emitting diode, orwherein at least one group of said inorganic light-emitting diodes is associated with a common, through aperture or a common, blind hole,wherein a group of said diodes is associated with a common through aperture or a common blind hole and wherein a diode carrier has a back face pressed against or adhesively bonded to the second main face or the third main face, the inorganic light-emitting diodes being reverse-mount diodes, and a front face with the group of diodes makes contact with the fifth main face or the sixth main face, the inorganic light-emitting diodes being reverse-mount diodes.
