Abstract
A lighting laminated glazing includes a first transparent glazing and a second glazing; an intermediate thermoplastic material layer; an electrically conductive layer between the first and second glazings; a capacitive touch sensitive device including a touch sensitive structure formed in the electrically conductive coating, having a ground electrode and a touch electrode having a touch sensitive area; a light emitting diode on the electrically conductive layer to indicate the touch sensitive area, the diode having a light emitting surface facing the touch sensitive area, and having a first and a second terminal electrically connected to, respectively, the ground electrode and the touch sensitive area; and a lighting device controlled by the touch sensitive device, the lighting device including a lighting element distinct from the diode, the lighting element being disposed between the first and the second glazing.
