Abstract

A light guide system includes a light guide and a carrier substrate having a barrier layer disposed therebetween. The barrier layer is introduced during a dual injection process to provide a permeable barrier between a first resin, used to form the light guide, and a second resin used to form the carrier substrate. The barrier layer allows for the first and second resins to bond, while acting as a wet-out inhibitor between the resins. The molded dual injection light guide system of the present invention provides for a unitary light guide and carrier substrate that has been molded with a barrier layer such that wetting out of a surface of the light guide is prevented along with the deleterious effects wetted out surfaces have on light transmission.
