Abstract: A method to form a light wave-guide optical element is disclosed. First, a flat organic optical layer is formed on an optically transparent substrate before using a template to transfer a pattern onto the flat organic optical layer to obtain a patterned organic optical layer. Then the patterned organic optical layer is cured in the presence of the template to obtain an organic optical material disposed on the optically transparent substrate before removing the template from the organic optical material. Later an anti-reflection stack is formed to conformally cover the organic optical material before applying an organic optical cover layer on the anti-reflection stack to cover the anti-reflection stack.

Abstract: An indirect troffer. Embodiments of the present invention provide a troffer-style fixture that is particularly well-suited for use with solid state light sources, such as LEDs. The troffer comprises a light engine unit that is surrounded on its perimeter by a reflective pan. A back reflector defines a reflective interior surface of the light engine.

A portion of the heat sink is exposed to the ambient room environment while another portion functions as a mount surface for the light sources that faces the back reflector. One or more light sources disposed along the heat sink mount surface emit light into an interior cavity where it can be mixed and/or shaped prior to emission. In some embodiments, one or more lens plates extend from the heat sink out to the back reflector.
