Abstract
Described herein are improved configurations for a lighting system with wireless power transfer that includes a source high-Q magnetic resonator coupled to a power source and generating an oscillating magnetic field, at least one device high-Q magnetic resonator configured to convert said oscillating magnetic field to electrical energy used to power a light coupled to the at least one device resonator, and at least one repeater resonator, larger than the device resonator, wherein the repeater resonator is positioned further from the source resonator than the device resonator and improves the power transfer efficiency between the source resonator and the device resonator.
