Thorough Testing Produces Fiber Lighting System

John V. DeNuto, Alan B. Toot and Matthew S. Mrakovich

A fiber optic distributed lighting system can illuminate exterior door handles, puddle lamps and running boards in vehicles, eliminating the need for incandescent lamps or light-emitting diodes in these high-moisture, -shock and -vibration areas. Distributed lighting offers vehicle designers flexibility in styling while offering manufacturers energy savings and improved reliability.

However, lighting system designers face stiff safety and reliability problems when considering any type of systems for production vehicles: thermal management, environmental performance (dust, heat endurance, vibration, and thermal and mechanical shock), manufacturability, luminous output and fiber uniformity....
