A semiconductor light emitting device package includes: a light emitting device; a wavelength conversion unit formed in a path of light emitted from the light emitting device and including a mixture of a wavelength conversion material and a glass material; and a reflective film disposed on an upper surface of the wavelength conversion unit and reflecting a partial amount of light emitted from the light emitting device and allowing a partial amount of light emitted from the light emitting device to be transmitted therethrough.

Semiconductor light emitting device package

A wavelength conversion structure comprises a sintered body comprising a mixture of a wavelength conversion material and a glass composition, wherein the wavelength conversion material comprises a phosphor and the glass composition comprises ZnO&#x2014;BaO&#x2014;SiO&#x2014;BO.

Wavelength conversion structure, apparatus comprising wavelength conversion structure, and related methods of manufacture

A method of manufacturing a white light emitting device includes dividing a phosphor sheet into phosphor film units to be applied to individual light emitting diode (LED) devices, measuring light conversion characteristics of the respective phosphor film units, classifying the phosphor film units of the phosphor sheet into a plurality of groups according to measurement results of the light conversion characteristics and combining the phosphor film units classified into the plurality of groups and an LED device having predetermined light characteristics so as to obtain target color characteristics.
