Abstract:
A lightguide (100) is disclosed. The lightguide includes a plurality of light extractors (120-123). Each light extractor is designed primarily to extract light that propagates within the lightguide and is incident on the light extractor from a first direction and reflect light that propagates within the lightguide and is incident on the light extractor from a second direction different than the first direction, toward another light extractor, where the other light extractor extracts the reflected light.
