Beschreibung
Zusammenfassung:	According to one aspect, a waveguide includes a body exhibiting a total internal reflectance characteristic and having a first face and a second face opposite the first face wherein the first and second faces extend along a lateral direction and a coupling cavity adapted to receive a light emitting diode (LED) that is configured to direct light into the body. The body additionally includes an extraction feature disposed on one of the first and second faces and configured to direct light traveling through the body out of at least one of the first and second faces. The body further includes a redirection feature disposed at least in part between the first and second faces and disposed between the coupling cavity and the extraction feature along the lateral direction, and configured to redirect light traveling through the body laterally within the body.
