1. A wireless lighting system comprising:

  • a source having a source resonator including one or more high-Q source magnetic resonators coupled to a power source and generating an oscillating magnetic field; and

    a device having a device resonator including one or more high-Q magnetic device resonators, distal from the source resonator and having a light-emitting part electrically coupled to the device resonator;

    wherein power is transferred wirelessly from the source resonator to the device resonator via the oscillating magnetic field and the light-emitting part is energized by an electrical energy captured by the device resonator, and wherein an amount of electrical energy transferred to the device resonator is controlled using wireless communications.
