Light-emitting diode lighting device comprising a communication device and installation comprising one such device

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.

2. A lighting device according to claim 1 comprising a receiver comprising a sensor sensitive to the initial radiation connected to a receipt signal processor.

3. A lighting device according to claim 2 wherein the receiver comprises an optical filtering means to let a light signal corresponding to an initial radiation pass and to reject a secondary radiation.

4. A lighting device according to claim 2 wherein the receiver comprises at least one electronic filter to reduce or eliminate a DC component of a signal representative of an optical signal received by the receiver.

5. A lighting device according to claim 1 wherein the electronic controller controls a power supply of at least one light-emitting diode for emitting a modulated light signal of said initial radiation by superposing a DC component and a modulation signal representative of a communication signal.

6. A lighting device according to claim 5 wherein the DC component depends on a value representative of the communication signal.

7. A lighting device according to claim 5 wherein the amplitude of the modulation signal depends on a value representative of the communication signal.
