Abstract
The lighting device comprises at least one emitter (10) of white light (9) produced by an initial radiation (1) and a secondary radiation (2), an electronic control circuit (11) to control the lighting, and a communication circuit (12). The electronic circuit (11) controls power supply of the light emitter to emit a modulating light signal (3, 4, 31, 36) of said initial radiation according to a communication signal (13). Said modulating light signal is designed to be received by a light signal receiver (18) sensitive to the initial radiation (1). A lighting installation comprises a power supply line, at least one lighting device (8) and at least one electrical apparatus (95, 96) connected to a receiver (18) comprising a sensor (19) sensitive to the initial radiation (1).

15. Lighting device comprising:
-
at least one light-emitting diode light emitter designed to emit white light by producing an initial radiation and a secondary radiation resulting from excitation of at least one layer of material reacting to said initial radiation, electronic control means connected to said at least one light-emitting diode light emitter to control the lighting, and at least first communication means connected to said control means, wherein the electronic control means control power supply of at least one light-emitting diode light emitter to emit a modulating light signal of said initial radiation according to a communication signal supplied by the first communication means, said modulating light signal being designed to be received by light signal receiver means sensitive to the initial radiation. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
