摘要： 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.

摘要： A modular light-emitting panel assembly has first and second light guides edge lit by respective light sources. Each light guide has a light input edge, opposed side edges, opposed major surfaces and a pattern of light extracting elements at at least one of the major surfaces. The light guides are juxtaposed with a side edge of the first light guide abutting a side edge of the second light guide at a seam and with the major surfaces nominally coplanar. Various embodiments of the panel assembly additionally include respective structures that reduce visibility of the seam when the light sources illuminate the panel assembly.

摘要： An LED lamp or LED lighting assembly includes a light guide having opposed major surfaces configured to propagate light by total internal reflection and a light input edge extending between the major surfaces. A light source is adjacent to the light input edge and is configured to edge light the light guide. In some embodiments, the light source is moveable relative to the light input edge, and the spectrum of the light output from the light guide may be adjusted by movement of the light source relative to the light input edge.

摘要： A light guide includes a first major surface, second major surface, and light input edge extending between the major surfaces, the major surfaces configured to propagate light input to the light guide therebetween by total internal reflection. Light extracting elements are at at least one of the major surfaces, at least one of the light extracting elements embodied as a cluster-shaped light extracting element and including an intersection portion and at least three members extending therefrom. Each member includes a first side surface and second side surface that come together to form a ridge or that are joined by a connecting surface, the ridge or connecting surface including a first end that intersects the major surface at which the micro-optical element is formed and extending to the intersection portion where the ridge or connecting surface intersects with one or more ridges or connecting surfaces of the other respective members.
