ABSTRACT:
A light emitting diode includes a lens, a chip base attached to a bottom of the lens, and an LED chip attached in the chip base to be concentric with the lens. The lens includes a bottom, an outer sidewall extending from the bottom, a first outer top surface extending from the outer sidewall, a second outer top surface extending from the first outer top surface and having a substantially conical groove-like shape, an inner sidewall forming a side of a central cavity formed by hollowing a central portion of the bottom, and an inner top surface extending from the inner sidewall and forming a ceiling of the central cavity. The substantially conical groove-like shaped second outer top surface has an angular point formed toward the central cavity, and the inner top surface is convexly formed toward the bottom.
