Abstract: According to one aspect, an optical waveguide includes a first waveguide portion and a second waveguide portion adjacent to and separate from the first waveguide portion. The waveguide portions include light coupling portions that are at least partially aligned and adapted to receive light developed by a light source. The first waveguide portion further has a first major surface with light direction features and a second major surface opposite the first major surface. The second waveguide portion further has a third major surface proximate the second major surface with an air gap disposed therebetween and a fourth major surface opposite the third major surface wherein the fourth major surface includes a cavity extending therein.
