Abstract: An illuminated, portable floor comprising a plurality of releasably, lockable panels having an array of illuminable members disposed in a desired design pattern in the upper surface of each panel, male and female mechanical coupling members disposed around the periphery of each panel for mechanically locking the panels in a side-by-side contiguous relationship, electrical male and female connectors mounted within selected locations along said mechanical coupling members of particular panels for electrically connecting the illuminable members of selected adjacent panels, a low voltage electrical power source, and an electrical circuit network connecting the power supply, the electrical connectors, and the illuminable members together. As the floor is assembled, the joinder of side-by-side panel edges effects both mechanical and electrical coupling simultaneously.
