Abstract
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.
