Abstract: Horizontal street lamp (10) of an oblong concave structure housing a source of light, with a downward-facing mouth in whose center is applied a frame (60) with a cavity into which a substantially vertical plate (80) can be freely inserted, said plate being illuminated by a source of light to create a sort of road sign, or for purposes of advertising, decoration generally.

Abstract: Outdoor lighting system including several lamps fixed in the ground by tubular rods and a flat supply cable laid on the ground and having two side-by-side wires of indefinite length for carrying electricity at a low voltage to the lamps. The electrical connection of the supply cable to a branch cable from each lamp is made by placing the supply cable in a longitudinal channel in the body of a terminal box of insulating material from which emerge the sharp points of contacts connected to the wires in the branch cable and positioned for engagement with the two wires in the supply cable, the channel being closed by a cover slidable over the terminal box body into a secured position in a longitudinal direction by hand without tools.
