Further information

How can product design be utilized as a differentiator in competitive markets? By using filigree lines of light in the final product, for example. To achieve this, BU Fiber Optics has developed an optical fiber in-house that emits light in all directions: this fiber creates an almost unlimited number of opportunities for ambient lighting and new approaches to product design.

AmbientFiber is characterized by its uniform emission of light at 360° across the entire length of the fiber – in contrast to a more punctiform LED illumination. The core of the optical fiber is Fused Silica, which works to prevent any discoloration effects or undesirable reactions to incident sunlight.

AmbientFiber can be used in a huge range of applications: in the automotive industry (interior and exterior lighting), in interior and emergency lighting applications for aircraft, ocean-going vessels and trains, in the field of automation and drives as a visual feedback system, and for building illumination in architecture and infrastructure. In the field of electrical appliances, AmbientFiber could be used to develop light-effect cables for electrical devices or illuminated charging cables. Interesting product developments are also possible in the wearables industry, which manufactures intelligent textiles and accessories that include illuminated hi-vis vests, footwear, and many more. When used with miniaturized sensors, AmbientFiber is also capable of indicating changes in temperature, pressure or humidity.
