Abstract
A wireless control is provided for a lamp, such as a fluorescent lamp, controlled by a ballast with a wireless control interface for RF communication. The receiver input and the transmitter output of the control interface module are connected to one or more electrode wires by a coupling capacitor(s) or a Lecher line transformer. During operation the lamp electrodes serve as the lamp antenna.
