摘要： A light device which is capable of generating a very diffuse light emission and, thus, avoids emission of a beam-light or a concentrated light. The device is highly effective as a personnel location indicator or decorative architectural item, since there is effectively no significant light beam. The light device is preferably designed for ground mounted use so as to serve as an indicator of a desired movement path or the like. The light devices comprises an outer housing with a source of light mounted within that housing. One of unique aspects of this lighting device is that it relies upon a fiber optic cable section which functions as a lens or filter through which light from the light source will pass. As the light passes through this lens, it becomes highly diffuse and, therefore, does not generate a light beam or source of concentrated light, as such. Rather, it merely generates a light at a ground level or other surface in which the device is mounted.
