Document Type and Number:

Japanese Patent JP6894931

Kind Code:

B2

Abstract:

The present invention relates to a lighting laminated glazing (100) comprising: - a first transparent glazing (1), preferably of mineral glass; - a second glazing (1'), preferably of mineral glass; - an intermediate layer (8) made of thermoplastic material, preferably polyvinyl butyral (PVB) for automotive glazing or ethylene vinyl acetate (EVA) for building glazing, bonding the second glazing (1') to the first transparent glazing (1); - an electrically conductive layer (2) disposed between the first transparent glazing (1) and the second glazing (1'); - a capacitive touch sensitive device (3) comprising a touch sensitive structure (30) formed in the electrically conductive coating (2), the touch sensitive structure (30) comprising a ground electrode (31) and a touch electrode (32) having a touch sensitive area (32a); - a light emitting diode (6) called indicator diode arranged on the electrically conductive layer (2) to indicate the touch sensitive area (32a), the light emitting diode (6) having a light emitting surface facing at least partially the touch sensitive area (32a), the light emitting diode (6) having a first terminal (61) being a first electrode zone electrically connected to the ground electrode (31) and a second terminal (62) being a second electrode zone electrically connected to the touch sensitive area (32a) - a lighting device (3') controlled by the touch sensitive device (3), the lighting device (3') comprising a lighting element (6', 6") distinct from the indicator diode (6), the lighting element (6', 6") being disposed between the first transparent glazing (1) and the second glazing (1').
