LED lens and LED package using the same

摘要

An LED lens includes a recess disposed in a quadrangular bottom surface of the LED lens and configured to have a light source disposed therein, wherein an internal surface of the recess, including lateral surfaces and top surfaces, is a light incident surface. The LED lens further includes a top surface forming a light exit surface, having a size greater than that of the bottom surface, and having a quadrangular shape; and lateral surfaces of the LED lens, disposed between the top and bottom surfaces of the LED lens, forming a reflective surface, and guiding light incident to the LED lens through the light incident surface to the light exit surface. The top surfaces of the light incident surface form an inverted quadrangular pyramid.
