摘要:
A light emitting device includes a first light emitter including a first light emitting chip emitting first blue light and at least one among a first phosphor and a second phosphor, the first light emitter being configured to emit second blue light, and a second light emitter including a second light emitting chip emitting third blue light and at least one among a third phosphor and a fourth phosphor, the second light emitter being configured to emit fourth blue light, wherein a ratio of an intensity of a peak wavelength of the fourth blue light to an intensity of a peak wavelength of the second blue light is greater than or equal to 0.6.
