Abstract: A lamp comprising electric contact members (9,10) at the outside of the lamp for making contact with corresponding electric contact elements (21,22) in a lamp holder surrounding the lamp. The light radiation of the lamp is emitted from the front side (2) of the lamp, which front side (2) is substantially located in a plane perpendicular to the longitudinal direction of the lamp. The contact members (9,10) are located near the circumferential edge of said front side of the lamp.

Abstract: An electrically powered modular furniture system comprising a first furniture member equipped with a low voltage electrical fixture, secured to a main surface of said first furniture member, and with low voltage conduit means comprising a pair of co-operating apertured conductor rails secured in an interfacial arrangement to a main surface of said first furniture member, the conductor rails comprising portions of a detachable electrical connector assembly is distinguished by its great simplicity in manufacture, its low cost and its versatility of application. It permits realization of combination furniture, which in practical use can be remodeled any time without the use of tools and which is so simple to mount that the mounting can be carried out by unskilled persons.
