Abstract
A mobile wireless receiver for use with a first electromagnetic resonator coupled to a power supply includes a load associated with an outdoor lighting unit that draws energy from the load to power a light source associated with the outdoor lighting unit, and a second electromagnetic resonator configured to be coupled to the load and moveable relative to the first electromagnetic resonator, wherein the second electromagnetic resonator is configured to be wirelessly coupled to the first electromagnetic resonator to provide resonant, non-radiative wireless power to the second electromagnetic resonator from the first electromagnetic resonator, and wherein the second electromagnetic resonator is configured to be tunable during system operation so as to at least one of tune the power provided to the second electromagnetic resonator and tune the power delivered to the load.
