Abstract
An optical device for distributing light produced by a white LED or other light-producing device includes a lens portion that refracts the light to provide a desired light intensity distribution, and a collimating portion that internally reflects light from the white LED. The optical device may be molded from an acrylic polymer material or the like. The reduced thickness of the device facilitates low cycle times and reduces warpage or other distortion that would otherwise be generated during the molding process.
