Abstract
A lighting system includes an electrically insulating and transparent or translucent optical material having a plurality of compartments containing a luminous composition, forming a light-emitting material. Structure for passing radiation, preferably radio frequency radiation, through the compartments is provided such that the luminous composition in the compartments will emit light through the optical material. The luminous composition is preferably a gas that is entrained as bubbles in the optical material when it is in the liquid state. The optical material is hardened to seal within the luminous gas and to produce a light-emitting material. Electrodes are used to pass the RF radiation through the light-emitting material. The electrodes can be provided as an adhesive-backed foil which is attached to the light-emitting material.
