1. A Light Emitting Diode (LED) based lighting device capable of Radio Frequency (RF) communication, said LED based lighting device comprising:
a driver board comprising a mains input connector, an LED output connector and an LED driver, wherein said LED driver is arranged for receiving a mains power supply, via said mains input connector, and for providing an LED current to an at least one LED, via said LED output connector;
an LED board comprising an LED input connector, an antenna and said at least one LED; and
an interconnect cable connecting said driver board to said LED board via said LED output connector and said LED input connector, for conveying said LED current from said driver board to said LED board;
wherein said driver board further comprises:
an RF module arranged for generating an RF signal and for superimposing said generated RF signal on said LED current such that said RF signal is conveyed over said interconnect cable to said antenna via capacitors that are provided between the RF module and the LED output connector,
wherein said LED board comprises:
an RF extraction module arranged for extracting said superimposed RF signal from said LED current and for providing said extracted RF signal to said antenna.
