Abstract:
1. A lighting system comprising: a multi-frequency generator connected to a power source and a controller, the multi-frequency generator configured to generate an oscillating signal at a selected one of a plurality of frequencies according to a control signal received from the controller; a transmitting coil connected to receive the oscillating signal; a receiving coil positioned so that an inductive coupling is formed with the transmitting coil; and a plurality of conditioning units connected to the receiving coil to receive the oscillating signal, and to a corresponding plurality of lights, individual ones of the plurality of conditioning units configured to power a corresponding at least one of the plurality of lights when the selected one of the plurality of frequencies matches a resonant frequency of one of a plurality of resonant circuits formed by the receiving coil, the transmitting coil, and a resonant capacitor in each of the plurality of conditioning units.
