Abstract: A modular method of manufacturing a waveguide is disclosed. The method includes positioning a mold insert including a plurality of mold prototypes, along at least one side wall of a molding equipment such that micro-optic structures of each mold prototype in the plurality of mold prototypes, faces a mold cavity. Each mold prototype extends along a length of the mold insert and the plurality of mold prototypes is disposed adjacent one another along a height of the mold insert. The method further includes feeding a material into the mold cavity for molding the material in the mold cavity to generate waveguide including a major surface having an optical pattern, where the optical pattern includes a plurality of elongated facets. Each of the plurality of elongated facets extends into the major surface and along a length of the waveguide. Further, the optical pattern extends along a height of the waveguide.

Abstract: Waveguides having improved illumination distribution and output luminance variation and lighting systems utilizing such waveguides are disclosed. The lighting systems generally include a light source which is optically coupled to a waveguide to distribute the light. The waveguides include one or more headlighting reduction regions and one or more output intensity shaping regions that work together to improve the distribution of light and reduce the effects of headlighting. The headlighting reduction regions may be integrated with the output intensity shaping region or may be an independent section.
