A refrigerator capable of being internally illuminated wherein the illumination is provided by an edge-lit panel of a substantially transparent material having two opposed surfaces of which at least one is within the refrigerator and on which a matrix of dots is applied so as to produce a light piping effect internally in to the refrigerator and wherein the light source of the edge-lit panel is located within the enclosed space of the refrigerator. One or more edge-lit panels may be used, which may be shelf of the refrigerator, or its side panels, back panel or roof panel. The edge-lit panel may be form from a transparent acrylic sheet, preferably containing an optical brightner. Protective transparent or translucent layer and a light diffuser may be applied to the surface carrying the matrix of dots. The refrigerators wherein the illumination provided by the edge-lit system according to the present invention have light more evenly distributed throughout the refrigerators and could be effectively illuminated by a light source of reduced wattage, thus reducing problems associated with dissipation of heat within the internal chambers of refrigerators.
