ABSTRACT:
A device is provided to diffuse a beam of light, the device consisting of a plurality of truncated cells nested together along their respective sidewalls for collecting and diffusing the light rays as they extend along the plurality of cells having an expansive, tapered interior volume. The device diffuses the main light beam in a headlamp, for example, thereby substantially reducing the glare experienced by oncoming drivers and permitting high beams of the headlamp to be used in the presence of the oncoming drivers. The device of the present invention is retrofitable to existing headlamps. In another embodiment of the present invention, a concave lens is disposed in the headlamp assembly to diffuse the main light beam prior to it entering the truncated cells, while each one of the cells of the dispersion device is also provided with its own respective concave lens to augment the diffusing effect.
