Title:
PHOSPHOR COMPOSITION, LIGHT-EMITTING DEVICE PACKAGE INCLUDING SAME, AND LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/188795
Kind Code:
A1
Abstract:
According to an embodiment, a phosphor composition and a light-emitting device package including the same comprise: 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.
