Abstract

A lighting assembly that includes a cornuate light guide and an annular light extracting and redirecting member. The light guide has a radial light input surface, an axial light input region, radial light output region and a flared region between input region and output region. Light input at the light input surface propagates to and within the light output region by total internal reflection at major surfaces of the light guide. The light extracting and redirecting member has a light extracting element in optical contact with an annular region of one of the major surfaces of the light output region, and a reflective light redirecting element to axially redirect the extracted light with a defined light ray angle distribution.
