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.

Abstract: A light guide includes opposed major surfaces, a light input edge extending therebetween, and light extracting elements at at least one of the major surfaces. At least a portion of the light extracting elements includes: a longitudinal axis extending between a first end and a second end of the light extracting element; a first side surface and a second side surface each extending from the major surface; and a ridge or end surface connecting the first side surface and the second side surface, the ridge or end surface extending along the longitudinal axis in a non-linear, winding path as viewed from a direction orthogonal to the major surface. In some embodiments, a cover element includes light redirecting elements having a ridge or end surface extending along a longitudinal axis of the element in a non-linear, winding path as viewed from a direction orthogonal to the major surface.

Abstract: A light guide assembly includes light guide segments, each including opposed major surfaces and a light input edge extending in the thickness direction therebetween. One of the light guide segments includes a first side edge surface including one or more side edge surface sections, at least a portion thereof oriented non-parallel to the thickness direction. Another of the light guide segments includes a second side edge surface complimentary to the first side edge surface. The one of the light guide segments is arranged adjacent the another of the light guide segments and abuts the complimentary second side edge surface, the one of the light guide segments variably positionable relative to the another of the light guide segments about an axis parallel to the length direction. A lighting assembly includes the light guide assembly and a housing assembly having housing segments, each associated with one of the respective light guide segments.
