Abstract

A light source is disclosed that includes an LED die including an emitting surface, and an extractor including a base, an apex smaller than the base, and at least one converging side extending between the base and the apex. The base is optically coupled to the emitting surface of the LED die. The light source also includes an optical element including an inner surface that forms a cavity. At least a portion of the extractor is positioned within the cavity such that the at least one converging side of the extractor is spaced apart from the inner surface of the optical element.
