Abstract
A laminated illuminating glazing unit includes a first sheet with a first main face, a second main face and an edge face, a second sheet with a first main face, a second main face and an edge face; a transparent lamination interlayer making adhesive contact with the second main face of the first sheet and with the first main face of the second sheet; a strip of light-emitting diodes (LEDs), including a printed circuit board and a plurality of LEDs, positioned so that the emitting faces of the LEDs face the edge face of the first sheet; and one or more scattering elements, wherein the lamination interlayer includes, on at least one of its main faces, an opaque masking layer extending from the edge of the interlayer toward the center of the glazing unit so as to cover a zone in which the light from the LEDs would, in the absence of the opaque masking layer, be visible, in the form of luminous halos, through the second sheet.
