Zusammenfassung:	A light modulation device is provided in an elevator installation having an elevator car for performing a method of modulating light in the elevator car. The light modulation device has a modulator that receives a first electrical signal from a control unit of the elevator installation, wherein the modulator, in order to modulate the first electrical signal, controls a lighting device in the elevator car having two or more light-emitting diodes. The lighting device generates a first light signal to encode the first electrical signal, and the modulator switches the light-emitting diodes on and off synchronously or asynchronously and/or adjusts their brightness.
