Abstract

A lighting system is described herein that may be energized by a plurality of sources. In one embodiment, a solar cell is capable of receiving light and converting the light into electrical signals. An energy conversion device may be included that converts movement of the energy conversion device into electrical signals. Additionally, an energy storage device receives and stores the electrical signals from the solar cell and the energy conversion device. The energy storage device is also adapted to supply energy to a lamp that emits light.
