IMPROVED SHEET GLAZING WITH INCORPORATED PHOTOSENSITIVE ELEMENT AND AUTOMATIC LIGHTING AND EXTINGUISHING DEVICE OF LIGHTS OF A MOTOR VEHICLE INCLUDING APPLICATION

摘要

THE LAMINATED GLAZING V ACCORDING TO THE INVENTION INCLUDES AS A PHOTOSENSITIVE ELEMENT A PHOTODIODE 1 OF THICKNESS AS IT IS DRAWN IN THE LAYER OF INTERLIMENT PLASTIC MATERIAL 5 OF THE LAMINATED GLAZING BETWEEN THE TWO EXTERNAL GLASS SHEETS 6 OF THE LAST 1, THE PHOTOD IT IS ADVANTABLY COATED HIMSELF IN A PLASTIC MATERIAL COMPATIBLE WITH THAT OF WHICH IS MADE UP THE INTERMEDIATE LAYER AND MOUNTED ALONG ONE OF THE SIDE EDGES OF THE GLAZING, SO THAT ITS CONDUCTORS 3 AND THEIR BORNS AND MAY BE MOUNTED CONNECTED TO ANY APPROPRIATE ELECTRICAL CIRCUIT. THIS ELECTRICAL CIRCUIT MAY PARTICULARLY BE THE LIGHTING CIRCUIT OF A MOTOR VEHICLE, SO THAT THE PHOTODIODE AUTOMATICALLY CONTROLS THE IGNITION OF THE LIGHTS OF THIS VEHICLE WHEN THE AMBIENT BRIGHTNESS FALLS BELOW SOME THRESHOLD AND EXTINCTION. THESE SAME LIGHTS WHEN THIS BRIGHTNESS EXCEEDS A SECOND THRESHOLD.
