SYSTEM FOR CONTROLLING A PLURALITY OF LIGHT SOURCES

摘要

A lighting system (100) comprises: a plurality of controllable lighting devices (2) each having an associated address (n); a central controller (10) for providing a command signal (Sc) including address command signals (AC(n)); at least one decentralized control unit (150) comprising an input (151) for receiving the command signal (Sc1N) and an output (152) for outputting an output command signal (SCOUT) including address command signals (AC(n)out)- Each lighting device is responsive to the address command signal (AC(n)) corresponding to its device address (n). The lighting devices are arranged in series for passing on the command signal, such that the output command signal is always identical to the input command signal. The DCU calculates, for at least one address X, an adapted output address command signal (AC'(X)out) differing from the corresponding input address command signal (AC(X)IN) and based on a function input signal received at its function input (156).
