Abstract
1368289 Lamps ISMOS DI GIORGIO SARTONI 19 Nov 1971 [10 April 1971] 53885/71 Heading F4R A modular lamp comprises a number of first sections, e.g. A, A<SP>1</SP>, B, assembled end to end by means of respective co-operating projections and recesses at opposite ends of each station, each of these ends being circular in cross-section, and a second, hood section C carrying a light source L and having a recessed end co-operating with the projection of an adjacent first section, wherein the co-operating recesses and projections permit rotation of any one section about an axis perpendicular to the centre of an end of the section for selective positioning thereof relative to an adjacent section. As shown, the projection 1 at one end of the first sections comprises a reduced diameter cylinder 1a having a flange 1b and the recess at the other end of the filament has radial flanges 2 for abutting the projection of an adjacent section. The section A or part-section A<SP>1</SP> is an open-ended cylinder, the section B is a segment of a toroid, and the hood C is ovoid in shape and is closed by a paraboloidal glass or plastics member 3. The partsections A<SP>1</SP> may provide a mounting arrangement for the lamp, alternatively a pedestal (P), Figs. 3 and 4 (not shown), may provide the required support. The lamp may be of the desk, wall or free-standing type.
