ABSTRACT:
Grooves or channels are formed along the edges, and/or at other selected locations, of a guitar, of other musical instruments; as might be done in purfling and binding for such instrument. A fiber-optic bundle is laid into the groove and overlayed with a veneer of suitable wood, or other appropriate materials, but in such a manner that ends of selected fibers are aligned with and/or extend through suitable apertures formed through the veneer overlay. The individual fiber-optic bundles are then gathered into a main fiber-optic trunk line which is directed through an entry channel and away from the instrument; terminating at a source of illumination. The source of illumination includes a light source in the form of a conventional light bulb and a color wheel formed with sections of different colors which are successively interposed between the light source and the end of the fiber-optic bundle; such that light from the light source passes through each colored section and illuminates the fibers of the bundle with the color of that section of the wheel. The light travels along the fibers and shows at the fiber ends distributed around the instrument. The wheel is such that it rotates due to the heat generated by the light bulb, but a suitable motor and controls may also be provided to rotate the color wheel. Appropriate controls are also provided to vary the intensity of the light and to otherwise control same.
