Abstract
1347839 Lighting fittings W HOCHMUTH [trading as CIMA INTERNATIONAL DIPL KFM W HOCHMUTH] 15 Dec 1972 [11 July 1972] 57923/72 Heading F4R [Also in Division G5] A glass fibre lighting fitting comprises a housing 1 containing a light source 6, a set of glass fibres 5 bunched at one end to engage the housing, and a guide body 10 connected to the housing and formed with a series of openings 11 through which the fibres extend individually or in groups. The body 10, which may be pivotally mounted, can be of spherical or planar form and the openings may be arranged to form illustrations, letters or numbers. The fibres may be enclosed in a transparent or translucent globe 12. The light source 6 is preferably a halogen lamp and is provided with a cold light reflector 7 and a heat filter 8. A multi-coloured filter 9 driven by a motor 19 is rotated in the path of the light, the filter being made up of a ring of sectorshaped components clamped between two metal discs (17, 18, Figs. 5 and 6, not shown) with interposed resilient layers (19<SP>1</SP>). The components may be replaced or arranged in a different sequence to vary the colour changing effect.
