1. A luminaire with a housing, comprising:
at least two radiation sources;
at least one switching possibility comprising a programmable logic that can amplitude-modulate at least one of the at least two radiation sources in such a way that signal transmission by at least one of the at least two radiation sources is made possible;
a lamp head; and
at least one directing means to direct an emission of the electromagnetic radiation emitted by the radiation sources, wherein the at least one directing means is provided in the form of a lens or a reflector,
wherein a first radiation source of the at least two radiation sources is arranged in a centre of the lamp head such that a second radiation source of the at least two radiation sources and a third radiation source of the at least two radiation sources are arranged concentrically with respect to the first radiation source,
wherein the second radiation source and the third radiation source are arranged alternately with respect to one another,
wherein the second radiation source and the third radiation source can be switched on and off,
wherein each of the second radiation source and the third radiation source emits electromagnetic radiation within a constant wavelength range when switched on,
wherein the second radiation source and the third radiation source can emit electromagnetic radiation within different wavelength ranges,
wherein the first radiation source and third radiation source have the same wavelength range and the second radiation source has a different wavelength from the first and third radiation sources.
