Abstract
A lighting fixture includes an optoelectronic light source, for example, designed to illuminate a room, and a modulatable supply circuit that is connected to the optoelectronic light source, wherein a current through or a voltage applied to the light source may be modulated by the modulatable supply circuit. A data stream generator is connected to a modulation input of the supply circuit. A trigger element that is connected to the data stream generator and configured to deliver a first signal to the data stream generator in response to a comparison of a counter value with a threshold value and an event signal. The data stream generator may be configured to deliver a modulation signal to the modulation input in response to an event signal and to the first signal, and the modulation signal encodes position information relative to a reference point.
