Abstract
In one embodiment, a solid-state luminaire has a strip of high power LEDs, where each LED emits light into an optical coupler. Light from the optical coupler is then coupled into a light guide. Light coupled into the light guide is mixed and guided to an exit aperture of the light guide. An optical extractor proximate the exit aperture of the light guide redirects light outward, which is optionally redirected generally downward by a secondary reflector that extends outwardly along the length of the light guide. The secondary reflector may be configured to create a variety of light-emission patterns. The luminaire may be hung from a ceiling, in track lighting, used as a pendant or pedestal fixture, or in other applications.
