ABSTRACT:
A laminated glass of the present invention includes as a photosensitive element a photodiode of such thickness that it can be buried in the plastic interlayer of the laminated glass between two outside glass sheets of the glass. The photodiode is coated in a plastic compatible with that from which the interlayer is made and mounted along one of the side edges of the glass, so that conductors from the diode and their terminals project out from the glass and can be connected to any suitable electric circuit. The electric circuit for use with the diode can be a lighting circuit of a motor vehicle so that the photodiode automatically controls turning on of the lights of the vehicle when ambient light falls below a certain threshold and turning off the same lights when ambient light exceeds a second threshold.
