Light emitting diode, light emitting diode package, method of manufacturing light emitting diode and illumination system

摘要

A light emitting diode (100) device according to the embodiment includes a substrate (110); a protective layer (120) on the substrate; an electrode layer (160) on the protective layer; a light emitting structure (145) disposed on the electrode layer to generate light and provided with a first semiconductor layer (130), an active layer (140) under the first semiconductor layer, and a second conductive semiconductor layer (150) under the active layer; and a first electrode (170) having a first end disposed on a top surface of the light emitting structure (145) and a second end disposed on the protective layer (120). The protective layer (120) comes into Schottky contact with at least one of the electrode layer (160) and the first electrode (170).
