The present document relates to Solid State Lighting (SSL) light bulb assemblies. In particular, the present document relates to the communication with such SSL light bulb assemblies. A communication system comprising a first and a second transceiver is described. The first transceiver comprises a magnet (311), and the second transceiver comprises a switched-mode power converter (222) which comprises an inductor element (207) with an inductor core material (302) having a magnetic field dependent permeability. The magnet (311) and the inductor core material (302) of the inductor element (207) are magnetically coupled. The first transceiver is configured to modulate a magnetic field generated by the magnet (311), 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 (423, 424) from the power converter (222). The measurement signal (423, 424) is dependent on an inductor value of the inductor element (207). |
