  • Patent number: 9986608
    Abstract: The lighting system includes a voltage source for generating a constant direct current adapted to supply lighting modules, a number n of electronic switches, a current sensor connected in series with the voltage source to detect a measurement signal indicative of the current provided by the voltage source, and a control unit. The control unit generates the drive signals for the electronic switches. It varies the drive signals, such that: in a first instant, all lighting modules are connected to the voltage source; and during a sequence of instants, each time a different set of lighting modules is connected to the voltage source. It then determines the current flowing through all lighting modules as a function of the measurement signal detected in the first instant, and determines the currents which flow through the various lighting modules as a function of the measurement signals detected during the sequence of instants.
