1. A wireless light-emitting diode (LED) driver, comprising:

  • a) an electrical energy transmitter comprising an inverter circuit coupled to receive an input power supply, and being configured to convert a received voltage signal to an AC signal;

    b) said electrical energy transmitter comprising N transmitter coupling circuits coupled to said inverter circuit, and being configured to be driven by said AC signal;

    c) an electrical energy receiver comprising M receiver coupling circuits coupled to said transmitter coupling circuits in a contactless mode, and being configured to receive said AC signal; and

    d) said electrical energy receiver comprising M rectifier circuits coupled to said receiver coupling circuits one by one, wherein each said rectifier circuit is configured to convert said AC signal to a DC signal to drive an LED load coupled to output terminals of said rectifier circuit, and wherein N and M are integers not less than 1.
