Abstract: According to an embodiment, a phosphor composition and a light-emitting device package including the same includes a first phosphor excited by an excited light source so as to emit light of a first wavelength area; a second phosphor excited by the excited light source so as to emit light of a second wavelength area; and a third phosphor excited by the excited light source so as to emit light of a third wavelength area. Therefore, light emitted from the phosphor composition has an improved color rendering index due to an increase in the intensity of light in a cyan wavelength area, and has an improved light velocity due to a shortened wavelength of light in a red wavelength area.

Abstract: An embodiment relates to a phosphor composition, a light-emitting device package comprising the same, and a lighting apparatus and, more particularly, to a phosphor composition comprising a first phosphor, excited by an excitation light source, for emitting a first wavelength range of light, a second phosphor, excited by the excitation light source, for emitting a second wavelength range of light, and a third phosphor, excited by the excitation light source, for emitting a third wavelength range of light. The light emitted from the phosphor composition exhibits an increased intensity of light in a blue-green wavelength region with the consequent improvement of color rendering index and a shortened wavelength of light in a red wavelength region with the consequent improvement of luminous flux.
