Abstract
Abstract For needed and/or decorative lighting in homes, offices, clubs and other dwellings, lighting units, such as light block units, usable as a single unit and in groups, create white and/or colored artificial light. They may be arranged, one adjacent another, as walls of light, decorative strips of light, room dividers of light, accent groups of light, and walls designs of light. Each light block unit has: at least one light source, comprising an electric light bulb, socket, and wires; a reflector caseback, which receives screw and/or adjesive fasteners to secure it to a building structure, which holds a light socket, to guide wires through the light block unit and on to adjacent light blocks, while the wires remain concealed throughout an overall arrangement of light block units, and which abuts adjacent casebacks at one or more preselected locations for the correct overall spacing of several light block units without requiring measurements beyond selecting the location of the first light block unit to be installed; a casefront or cover to conceal the caseback and its electrical attachments while providing an overall light passing cover, which is preferably snapped on and off providing ready access to the bulb, which may be white or colored. Several light block units, up to a presently recommended limit of thirty-six may be connected to the same lead-in electrical circuit, which inturn may incorporate several plugs and switches.
