Patent ID: 8277072

Claim:
A solar-powered lighting system, comprising: a substrate comprising at least one light diffusion layer and a plurality of light guiding layers adjacent to the light diffusion layer; at least one solar chip disposed on at least one lateral surface of the substrate; and at least one light source disposed on at least one lateral surface of the substrate, wherein electrical power for the at least one light source to emit light is generated by the at least one solar chip collecting solar light energy from solar light entering the substrate and propagating therein, wherein solar light enters the substrate and is diffused by the light diffusion layer, and the diffused solar light is reflected by an interface of the light diffusion layer and the light guiding layer for solar light energy collection by the at least one solar chips, and a portion of the solar light enters the light guiding layers and is reflected by the interface of the light guiding layers, wherein the solar light energy of the reflected light is collected by the at least one solar chips, and wherein the light emitted from the light source is emitted to the substrate and is guided by the light diffusion layer and the light guiding layers to leave the substrate.
