In an arrangement of lighting devices (10), a remote control device (30) and a central control device (20), a particular lighting device to be controlled by means of the remote control device may be selected by a user transmitting a selecting command (42, 43). When the central control device receives the selecting command (44), it carries out a selection sequence (45) during which it controls the lighting devices in one or the other sequence so as to have their output change temporarily (45, 46, 47). If the remote control device, which is directed to the particular lighting device (41), senses such an output change (50), it transmits data representing such an event (51) to the central control device. When the central control device receives such event data (52), it determines the particular lighting device as that to which the remote control device is directed (53) for subsequent control (54) of this particular lighting device. |
