摘要：
Various embodiments disclose an illumination apparatus. The apparatus may comprise a light guide supporting propagation of light and having at least a portion of one of its edges comprising an array of microstructures. These microstructures may be incorporated in the input window of the light guide to control the light intensity distributed within the light guide. In certain embodiments, the directional intensity of the light entering the light guide may be modified to achieve a desired distribution across the light guide.
