摘要

The method involves emitting radiation such as infrared or ultraviolet radiation, with respective intensities in a temporal unit by radiation sources e.g. lamp (A) such as LED, where one of the definable essentially constant intensities is constant and another intensity is variable with a carrier frequency. A part of data is transferred by a phase relationship of the carrier frequencies of the radiation sources. The intensities of a part of the radiation sources are specified such that the radiation is suitable for lighting, where the radiation contains a single wavelength. An independent claim is also included for an arrangement for the transmission of data with two radiation sources for the emission of radiation.
