Abstract:
This invention discloses an optical device for a semiconductor based lamp, the optical device comprising a base for mounting a semiconductor based light-emitting device, and a light-redirecting member having an opening and a reflective surface next to the opening, wherein the opening is aligned directly above the semiconductor based light-emitting device, and the reflective surface redirects light emitted from the semiconductor-based light-emitting device to lateral directions.
