Abstract
A communication system with SSL light bulb assemblies comprises a first and a second transceiver. The first transceiver comprises a magnet, and the second transceiver comprises a switched-mode power converter which comprises an inductor element with an inductor core material having a magnetic field dependent permeability. The magnet and the inductor core material of the inductor element are magnetically coupled. The first transceiver is configured to modulate a magnetic field generated by the magnet to generate a modulated downstream magnetic field indicative of downstream data, and the second transceiver is configured to extract the downstream data from a measurement signal from the power converter. The measurement signal is dependent on an inductor value of the inductor element.
