Abstract

A decorative light tile includes a base, a light source adjacent to the perimeter of the base positioned to illuminate at least a slanted light reflecting area of the base, and a cover mounted on the base adapted to be illuminated by light from the light source reflected off the slanted light reflecting area. Additionally, the light tile includes a bus bar system. The bus bar system includes positioned along a perimeter of the light tile. The bus bar system is electrically connected to the light source and provides a circuit for supplying power to the light source. A light tile system includes a plurality of light tiles, a decorative sheet positioned adjacent to each light tile and illuminated by the light source within the light tile, and a power supply. Each light tile includes a bus bar system connected to a light source within the light tile and the light tiles may be positioned contiguous to each other so that the bus bar systems are in electrical contact with each other.
