Abstract: An illumination system for incorporating light into unit paved or stepping stone surfaces comprises at least one illuminated paving block which includes at least one light source and at least one optical fiber, in communication with the light source, imbedded in the paving block, and is sufficiently strong and durable. A plurality of optical fibers is preferably included within the block having first ends positioned to collect light from the light source and second ends positioned to be exposed at the top surface of the block to provide a plurality of points of light visible at the top surface. The paving block is self-contained and includes a circuit module for housing the light source and an electrical supply means for connecting the light source to an external electrical power source. The illumination system preferably comprises a plurality of illuminated paving blocks connected together and to a source of electricity to form lighted pathways, walkways, floors or large illuminated surfaces.
