Abstract
A lens including an upper surface having a curved portion having a changing curvature in a direction extending away from a central axis of the lens, and a lower surface having a concave portion disposed on the central axis of the lens. The concave portion of the lower surface includes an entrance disposed on a lower region of the concave portion and configured to receive light emitted from a light-emitting diode chip, and an upper end surface disposed on an upper region of the concave portion. The concave portion includes a width that narrows in a direction extending away from the entrance. The upper end surface is nonplanar.
