Abstract:
1. A lighting device comprising: at least one light-emitting diode for emitting white light by producing an initial radiation and a secondary radiation resulting from excitation of at least one layer of material which reacts to said initial radiation; an electronic controller for controlling the lighting connected to said at least one light-emitting diode; at least one communication means for transmitting data connected to said electronic controller; and a light signal receiver sensitive to the initial radiation and able to receive a modulating light signal from said at least one light-emitting diode; wherein the electronic controller controls a power supply of at least one light-emitting diode, said at least one light-emitting diode for emitting a modulating light signal of said initial radiation according to a communication signal transmitted by the at least one communication means.
