Abstract
A lighting system for wirelessly providing power to a lighting assembly across a wall. The lighting system may be used, for example, for powering the lighting assembly positioned on an outside portion of the wall, such as on the outside of a boat hull. An example of the lighting system includes a power transmitter with a multi-frequency generator connected to a power source and a controller. The multi-frequency generator is configured to generate an oscillating signal at a predetermined frequency according to a control signal received from the controller. The power transmitter includes a transmitting coil connected to receive the oscillating signal. A receiving coil is positioned to form an inductive coupling with the transmitting coil. A plurality of conditioning units are connected to the receiving coil to receive the oscillating signal. The plurality of conditioning units are connected to provide power to a corresponding light or set of lights. The conditioning units provide power to the corresponding 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, transmitting coil…
