Abstract
Abstract This invention relates to decorative hanging lighting apparatuses adapted to be hung from the ceiling, etc., and comprised of a plurality of lighting units coupled in the vertical direction. In the aforementioned lighting unit, for facility in coupling lighting units and for obviating the wiring work, there are provided two hooking members each having hooking means at both ends thereof and formed of an electric conductor, with electrode wires of an electric bulb or electric bulbs connected respectively to the aforementioned two hooking members. The top hooking means of one of the aforementioned lighting units are hooked on the bottom hooking means of the aforementioned other lighting unit which is placed above the former lighting unit, to couple these lighting units, thereby comprising the aforementioned decorative hanging lighting apparatus.
