LENS FOR LIGHT EMITTING DIODE PACKAGE AND LIGHT EMITTING DIODE PACKAGE HAVING THE SAME

摘要

PURPOSE: A lens for a light emitting device package and a light emitting device package including the same are provided to increase light extraction efficiency by preventing light form a light emitting device chip from being reflected to the inside by a lens surface. CONSTITUTION: A lens for a light emitting package covers a light emitting device chip mounted on a package body. The outer surface protruded to the upper side of the package body has one main curvature. The lens includes a plurality of refractive lenses(50) formed along the main curvature. The refractive lens is protruded from the outer surface of the lens. The refractive lens has a sub curvature smaller than the main curvature.
