Beschreibung
Zusammenfassung:	A fiber optic cable (10) suitable for lateral illumination lighting installations has a tubular central core (12), wrapped perimetrically with angularly evenly distributed bundles (15) of optical fibers (16) and covered with a transparent sheath (17). The core includes an outer cylindrical surface (14) of reflective material (24) that deflects inwardly directed lateral emissions back outwardly, so they can contribute usefully to the visible light. In manufacture, the bundles are wound about the core by a cabling machine which simultaneously extrudes the sheath about the winding. In a modified embodiment, a cable (10') includes an arcuate cutout (30) that mates with a complementary track (39, 40) of a mounting strip (35) . Strip (35) includes a reflective substance in an area (38) between upper and lower cables (10') to present a continuous, top to bottom lateral illumination effect. In another form of the modified embodiment, the fiber bundles are provided directly within upper and lower reflective channels (41) formed integrally within the mounting strip.
