Abstract
The present invention relates to a linear light form, and its method of manufacture, having a light diverting outer layer that reflects and/or refracts ambient light directed towards the light form. The linear light form includes a light transmitting core, clad with a fluoropolymer cladding and subsequently jacketed with a polymeric finish jacket. A light diverting layer either inserted between the cladding and the jacket or surrounding the jacket is included in the linear light form. The light diverting layer preferably has the property of allowing light to be transmitted from the core out of the light form in one direction and reflecting ambient light directed towards the light form.
