An illumination package is disclosed in the invention. The illumination package includes an optical element, package base, and a light emitter. The optical element is designed to redirect a majority of light emitted from the light emitter to a direction approximately perpendicular to a longitudinal axis of the optical element. In one embodiment, the optical element includes an flared portion and a base portion. The flared portion is constructed by an upper surface forming a recess, a side surface adjacent to the upper surface and curved, and a lower surface connecting to the base portion. In another embodiment, a concave lens is formed on the upper surface. |
