Phosphor and light emitting device having the same

A light emitting device comprising:

• 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 comprising the phosphors,
• wherein the phosphors have mutually different color spectrums,
• wherein a light emission spectrum of a mixture of lights emitted from the phosphors comprises yellow based light,
• wherein a luminous intensity at a peak wavelength of the light emission spectrum has a flat section in a range of 35 nm to 40 nm,
• wherein the flat section has a gradient having a deviation of 0.4% or less based on a horizontal linear line of the luminous intensity at the peak wavelength,
• wherein one of the plurality of phosphors has a content having at least 70% of a sum of contents of the plurality of phosphors,
• wherein the one of the plurality of phosphors is a green phosphor and is formed of one type of phosphor,
• wherein the phosphors includes 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, and
• wherein the first to third phosphors comprise mutually different nitride phosphors.
