The lighting installation comprises an electrical power supply line ( 3 ) and at least one lighting device ( 21 A; 21 B; 21 C) with controllable light emission, connected to said electrical power supply line ( 3 ). Each lighting device is associated with a control unit ( 25 A, 25 B, 25 C) comprising a device ( 30 ) for receiving data transmitted along the electrical power supply line ( 3 ) and devices ( 41; 60 ) for generating a light emission regulation signal. The electrical power supply line is connected to a controller ( 27 ) with a means ( 83 ) of transmitting data toward the control unit ( 25 A, 25 B, 25 C). Additionally, the controller is programmed to send at least one data element to the control unit for regulating the emission of the corresponding lighting device.
