Abstract (en)
[origin: WO9737170A1] A row of transparent tubes (32, 34, 36) are each formed from a semi-rigid rectangular plate (10) of transparent policarbonate, which is coated with a total-internal-reflection film (20) on one of its surfaces and is arched with its longer sides brought together and clamped. The clamping means may comprise a grooved shoe (26) for receiving longitudinal, square-bent edges (12, 14) of the plate (10) and a girder (28) bolted to the shoe. A light guide is assembled from several trunks which are connected to one another . Each guide trunk (32, 34, 36) is hung to a horizontal rail (38) by means of hooking brackets (40) which are fastened to straps (41). The trunks are connected end-to-end by means of fittings comprising pairs of rings (42, 44) which are also further described below. At one end of the guide, a light source is attached, i.e. a focused projector (46) which is also hung to rail (38) through a bracket (40).
