ABSTRACT:
An article configured for emitting diffuse light in a predetermined set of directions when coupled with a light source includes a light fiber and a diffuse reflective sheet material disposed around at least a portion of the light fiber to direct at least a portion of the light emitted by the light fiber toward the predetermined set of directions. The light fiber has a light receiving end for coupling to the light source and the light fiber emitting light when coupled to the light source. A variety of diffuse reflective sheet materials can be used including, for example, microvoided sheet materials, such as those made by the TIPS ("thermally induced phase separation") method, and microporous sheet materials.
