Abstract: An illuminated optical fiber display system for Christmas trees, ornamental displays and signs and the like, in which an elongated column having a hollow interior contains a fluorescent light tube and the column supports a plurality of optical fiber elements enclosed in a sheath extending outwardly from the column and having the inner ends in a position to receive light from the fluorescent light tube in the column. The optical fiber elements may be decorated to resemble evergreen branches. The fluorescent light or a sleeve around the fluorescent light, containing colored and shaded areas, is rotated to vary the lighting characteristics emitted from the outer ends of the optical fiber elements. The concept involved in the present application has sufficient versatility that the sleeve and/or fluorescent light and the shading and coloring thereon may be varied to provide the ornamental characteristics desired.
