Abstract
Embodiments of this invention include composite articles having specific optical properties. In one embodiment of this invention, a composite comprises high and low refractive index light transmitting material and surface relief features. In further embodiments, the composite comprises volumetric dispersed phase domains that may be asymmetric in shape. In one embodiment of this invention, the composite is an optical film providing light collimating features along two orthogonal planes perpendicular to the surface of the film. In another embodiment, the composite has improved optical, thermal, mechanical, or environmental properties. In further embodiments of this invention, the composite is manufactured by optically coupling or extruding two or more light transmitting materials, and forming inverted light collimating surface relief features or light collimating surface relief features. In further embodiments of this invention, a method of manufacturing a composite comprises forming one or more surface relief features on a component and injection molding or otherwise optically coupling two or more materials to the component. In one or more embodiments of this invention a light sourc…
