Abstract
Provided are an energy harvesting device capable of generating electric energy by effectively obtaining an electromagnetic wave emitted from an indoor lighting device and a power control system of a lighting device capable of performing self-power generation by using the energy harvesting device as a power source. The energy harvesting device using an electromagnetic wave according to an exemplary embodiment of the present disclosure includes: an interface unit made of a conductive material and configured to capture a conductive interference signal transferred through a conductive member of a lighting device; and a rectifier circuit unit configured to rectify the captured conductive interference signal to convert the rectified conductive interference signal to direct current power.
