Abstract:
An edge-lit lighting apparatus includes a light source and a light guide body. The light guide body includes an input edge, the light source positioned to project light through the input edge in a primary emission direction, the light guide extending from the input edge. The light guide body includes a mean elongation plane which is angularly offset from the primary emission direction. The light guide body includes a reflective side adjacent the input edge and configured to redirect light from the light source. The light guide includes an output side configured to disperse redirected light from the reflected side. The light guide body can extend curvilinearly from the input edge. The lighting apparatus can be configured as an indirect lighting system, and can help increase efficiency for edge-lit lighting systems.
