US Patent 7784965 Solid state light illuminator

A solid state light illuminator includes a solid state lighting element, a primary coil, and a secondary coil. The secondary coil and the solid state lighting element cooperatively form a circuit. The secondary coil couples electromagnetically with the primary coil. The primary coil is adapted for electrically connecting to an AC power source to generate an alternating magnetic field. The alternating magnetic field generates an induced electromotive force in the secondary coil to apply an electrical current to the solid state lighting element.
