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).
