Abstract

A light guide includes opposed major surfaces and a light input edge extending therebetween. An array of micro-optical elements of well-defined shape at at least one of the opposed major surfaces corresponds to the light input edge. Each of the micro-optical elements in the array includes a longitudinal axis arranged within the range of angles relative to the light input edge. A path linearly extending along the light guide from the light input edge intersects at least a portion of the micro-optical elements in the array, at least one of the micro-optical elements along the path arranged with its longitudinal axis at a positive angle relative to the light input edge, and at least another one of the micro-optical elements along the path arranged with its longitudinal axis at a negative angle relative to the light input edge.
