Abstract
A laminated vehicle windshield for head-up display, includes a first glazing, forming an exterior glazing, a lamination interlayer made of polymeric material, the lamination interlayer having a cross section which decreases in wedge shape from the top toward the bottom of the laminated glazing, a second glazing, forming an interior glazing, the second main face and the third main face being the internal faces of the laminated glazing, a set of diodes, each diode emitting in the direction of the interior glass. For each of the diodes, the lamination interlayer includes a blind aperture housing the diode.
Claims20
A vehicle laminated windshield for head-up display, comprising:
- a laminated glazing comprising:
- a first glazing, forming an exterior glazing, with first and second main faces;
- a lamination interlayer made of polymeric material, the lamination interlayer having a cross section which decreases in wedge shape from a top toward a bottom of the laminated glazing;
- a second glazing, forming an interior glazing, with third and fourth main faces,
- the second main face and the third main face being the internal faces of the laminated glazing,
- between the second main face and the third main face, one or more inorganic light-emitting diodes, each inorganic light-emitting diode having an emitting face capable of emitting, in a direction of the third main face, a signaling light, and each inorganic light-emitting diode having an edge face, each inorganic light-emitting diode being of submillimetric thickness,
- for each inorganic light-emitting diode, the lamination interlayer comprises a blind aperture surrounding the edge face of the inorganic light-emitting diode and/or, for a group of inorganic light-emitting diodes, the lamination interlayer comprises a common blind aperture surrounding said group of inorganic light-emitting diodes,
- wherein the lamination interlayer is formed either by a single sheet of polymeric material or by a laminated assembly of at least a first sheet and a second sheet of polymeric material,
- said single sheet having a first main face in which a first cut-out portion is present to form said blind aperture or said common blind aperture,
- said first sheet of polymeric material being of unvarying thickness and said second sheet of polymeric material having a cross-section which decreases in wedge shape from the top toward the bottom of the laminated glazing, said first sheet of polymeric material or said second sheet of polymeric material having a second main face in which a second cut-out portion is present to form said blind aperture or said common blind aperture.
