Abstract:
A fiber optic decorative tree, comprising:(a) a base unit having an interior chamber;(b) a light source disposed within the interior chamber of the base unit, light produced by the light source directed through an opening on an upper surface of the base unit;(c) an elongated and perforated center tube having a top end and a bottom end, the center tube being substantially vertically oriented, and removeably mounted on the base unit so as to be positioned, at least in part, over the opening, said center tube is tapered with the bottom end having a greater diameter than the top end; the center tube being segmented wherein the diameter of successive segments decreases from the bottom of the center tube to the top of the center tube;(d) a plurality of light conducting optical fibers having a first end and a second end, the optical fibers disposed partially within the center tube with the first end of each fiber located near the bottom end of the center tube and suitably positioned to enable light from the light source passing through the opening to be suitably coupled into each respective optical fiber; the optical fibers extending up the interior of the center tube, at least partially, and passing through a respective perforation, the size of each perforation may be one selected from a predefined number of available sizes to accommodate one or more optical fibers, with the second end extending radially outwardly from the center tube, with light emitted from the second end of the optical fibers to produce a decorative effect;(e) a motor with a low speed output shaft;(f) a disk comprised of a plurality of colored regions formed of transparent material suitably positioned so that light from the light source passes through the disk before passing through the opening, the disk rotatably mounted on the shaft of the motor to enable each region to be sequentially rotated past the light source to vary the color of the light coupled to the light conducting optical fibers, wherein the rotation of the disk is paused for a predetermined temporal period once a respective colored region is positioned between the light source and the opening, the pausing of the disk maintaining each particular color made available via the colored regions of the disk for the predetermined temporal period.
