ABSTRACT:
A flexible transmitting guide has a substantially transparent semi-solid core to which is shrink-fitted, or otherwise tightly clad, a transparent or translucent sleeve which is designed to laterally diffuse, disperse or refract a substantial component of light away from the core as it traverses the length of the guide. Thus, the clad core appears bright along its length and functions as a primary light source. In modifications of the device, the lateral dispersion of light passing along the core is enhanced by interposing cuts or discontinuities at intervals along its surface, or by providing a sleeve comprising an emulsion of light-reflecting particles. The light source may be adjacent to or separated from the core, and may comprise either a steady state, or pulsating source, ahead of which colored filters may be inserted, if desired. Numerous indoor and outdoor applications are contemplated for light guides in accordance with the present invention, including for signs, safety vests for traffic policemen, lighted canes for the disabled, lights for instrument panels, safety lights for vehicles and ships, and lights for interior and exterior decoration.
