ABSTRACT:
A light emitting diode package includes a light emitting diode device and a lens encapsulating the light emitting diode device. The lens includes two reflective surfaces disposed at either side of a central axis, and a plurality of diffractive surfaces disposed between the reflective surfaces and each of the diffractive surfaces has a tilt angle respective to the central axis. Portions of light beams incident to each of the reflective surfaces are reflected to at least one diffractive surface and are diffracted and collected into a convergent angle.
