Abstract:
Disclosed herein are a light emitting device and a method of making the same. The light emitting device includes: a substrate including a first lead and a second lead; a light emitting diode disposed over the first lead of the substrate, including a second conductive-type semiconductor layer, an active layer, and a first conductive-type semiconductor layer, and emit near ultraviolet light; and a wavelength conversion unit disposed over the light emitting diode and spaced apart from the light emitting diode, wherein the light emitting structure has semi-polar or non-polar characteristics, the wavelength conversion unit has a multi-layered structure including a first phosphor layer and a second phosphor layer, and the light emitting diode is driven at a current density which is equal to or greater than 350 mA/mm2.
