Abstract

A low-voltage light construction created by tube construction elements made up of male and female embodiments of electrically insulated metal tubes or metal rods and metal tubes. The male embodiment is connected to a low-voltage energy source by two circuit extensions, whereas one extension is electrically connected to the inner rod and the other extension is electrically connected to the outer tube. The construction provides simple assembly possibilities and enables numerous arrangements using a variable amount of connecting tube elements which are pushed together by manual pressure. The tube sections are set symmetrically to the illuminants and can be rotated around their axes. The illuminants are set in two pin circuits, which are connected to a pair of electrically conducting bars. These are held to the metal tube elements by round headed nuts. This makes it possible to rotate the illuminants on two additional axes. Each illuminant can thus be rotated independently around three axes, providing multi-directional lighting capability depending on the user's preference.
