Abstract

A lighting system having an operating device and a plurality of lamps. The operating device serves to control the lamps. Each of the lamps has an identification transmitting unit, which serves to control the particular lamp at least temporarily in such a way that the particular lamp outputs an identification light signal to be uniquely identified. An identification receiving unit, which receives the identification light signals of the lamps, is integrated in the operating device. The lighting system is designed in such a way that only lamps whose identification light signal is presently received by the identification receiving unit of the operating device at the time of the output of a control signal for controlling the lamps or within a defined time period therebefore can be controlled.
