Abstract
A vehicle luminous signaling glazing unit forming a front windshield, includes a first glazing pane, forming the exterior glazing pane, with first and second main faces F1, F2; a lamination interlayer made of a polymeric material of thickness e1 of at most 1.8 mm; and a second glazing pane, forming the interior glazing pane, with third and fourth main faces F3, F4, the face F2 and the face F3 being the internal faces of the laminated glazing unit; and a set of diodes on a front face of a PCB board, the assembly being of thickness et2≤e1, each diode emitting in the direction of the interior glass, and each diode having an edge face. For each of the diodes, the lamination interlayer comprises a through-aperture encircling the edge face of the diode, and the lamination interlayer is between face F3 and the front face of the PCB board.
