Abstract

An inductively coupled LED lighting system including an LED light module mountable on one side of a surface of a partition and a power module mountable on an opposing surface. The LED light module and the power module are aligned to allow for an inductive transfer of power. The LED light module includes a first coil connected to one or more LEDs. The LED light module also includes a base, a lens fixed to the base enclosing the circuitry in an enclosure and attachment means for attaching the LED light module to a surface. An alternating current or a direct current power source is connected to the power module. Alternating current or pulsed direct current is directed through a connected first coil creating a fluctuating inductive field. Electromagnetic power produced in the power module coil is inductively transferred to the coil in the LED light module powering the LEDs.
