The solar light collecting means and by using sunlight as a backlight of a liquid crystal display

The present invention provides a solar collection device comprising a lens substrate, a plurality of Fresnel lenses, the connector board, a plurality of fiber optic connectors and light chasing substrate. The lens substrate having a plurality of circular hollows. A plurality of Fresnel lenses corresponding to the plurality of circular hollows provided on the lens substrate. The connector is disposed substantially parallel to the substrate lens substrate, and the focal distance of the lens substrate. Said plurality of optical fiber connectors adjustably disposed on said connector substrate. The substrate chasing light lens disposed between the substrate and the substrate connector for the lens substrate while rotating the substrate and the connector, so that the plurality of the Fresnel lens facing the sun. The present invention further provides a liquid crystal display device using sunlight as a backlight.
