Abstract:
Disclosed are a phosphor and a light emitting device having the same. The light emitting device includes a light emitting chip, a plurality of phosphors to absorb a portion of light emitted from the light emitting chip and to emit lights having mutually different peak wavelengths, and a molding member provided on the light emitting chip and including the phosphors. The phosphors include a first phosphor to emit light having a first peak wavelength, a second phosphor to absorb the portion of the light emitted from the light emitting chip and to emit light having a second peak wavelength, and a third phosphor to absorb the portion of the light emitted from the light emitting chip and to emit light having a third peak wavelength. The first to third peak wavelengths have mutually different color spectrums, and a light emission spectrum in which the first to third peak wavelengths are mixed with each other has a luminous intensity having a substantially flat section in at least 30 nm at a peak wavelength thereof.
