Abstract

The present application discloses a light source comprising an LED die having an emitting surface and an optical element including a base, an apex smaller than the base, and a converging side extending between the base and the apex, wherein the base is optically coupled to and is no greater in size than the emitting surface, and wherein the optical element directs light emitted by the LED die to produce a side emitting pattern.
