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.
