Lighting system with induction power supply
Abstract
A system for producing light is provided. The system comprises a sealed enclosure surrounding a porous graphite foam conductor which is exposed to an electromagnetic field generated by an oscillating circuit. When exposed, the foam conductor conducts induced electric current which heats the same to product light. The amount of light is controllable by changing the output of a drive circuit. The oscillating circuit comprises a first inductor and a first capacitor. The first inductor has a first terminal and a second terminal. The output of the drive circuit is controlled by turning a MOSFET OFF and ON. The MOSFET is turned ON when an integrated signal representative of a difference between a voltage proportional to the first terminal and a voltage proportional to the second terminal is between a first voltage threshold and a second voltage threshold and based on a timing signal.
