Abstract
Abstract A floor panel, suitable for assembly with similar panels into an illuminated portable floor, takes the form of a rectangular wooden panel having a number of first apertures in its lower face and a number of second apertures in its upper face, each second aperture intersecting one of the first apertures, a number of illumination devices such as light-emitting diodes or incandescent lamps located in the first apertures, one or more transparent or translucent covers over the second apertures, and electrical connectors such as electric wires to convey power to the illumination devices from the underside of the panel.
