1. A solid state light illuminator, comprising:
- a primary coil configured to electrically connect to an alternating current power source to generate an alternating magnetic field;
a secondary coil coupling electromagnetically with the primary coil;
a solid state lighting element electrically connected to the secondary coil, wherein the alternating magnetic field generated by the primary coil, generates an induced electromotive force in the secondary coil to apply an electrical current to the solid state lighting element; and
a first iron core and a second iron core, wherein the primary coil is wound around the first iron core and the secondary coil is wound around the second iron core;
wherein the first iron core and the second iron core are in electrically non-contacting state, and a distance between the first iron core and the second iron core is in a range of 0.1-0.3 mm.

Abstract
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.
