Abstract
An illumination device includes a light-pervious substrate, a solid-state light source and at least one solar cell. The substrate has a bottom surface, a light incident surface adjacent to the bottom surface, and a light emitting surface opposite to the bottom surface. The solid-state light source is arranged on the light incident surface for emitting light into the substrate through the light incident surface. The at least one solar cell is arranged on the bottom surface of the substrate to absorb and convert solar energy into electric energy and supply the electric energy to the solid-state light source.
