Abstract
The present invention relates to an illumination fiber optic (20) or an assembly including illumination fiber optics contained in a first polymeric layer (26) or in a channel and the first layer or channel including intumescent or other fire retardant material, and further contained within a second outer layer (28) or jacket made of a polymeric material which has the property of containing the combination sufficient to hinder the propagation of the fire and eventually extinguishing the flame. The fiber optic may be side light emitting, with the core, layer, channel and fire retardant materials being transparent or translucent, or may be end light emitting with the fiber optic being a layer core fiber optic and the outer layer being opaque.
