Abstract
A light emitting device includes multiple types of solid state light emitting elements having different peak wavelengths from each other; and a wavelength converter including phosphors that convert a wavelength of light emitted from each of the solid state light emitting elements. The phosphors include two or more of a first phosphor, a second phosphor, and a third phosphor. The first phosphor is excited by light emitted from a solid state light emitting element having a relatively long peak wavelength, and the second phosphor is excited by light emitted from a solid state light emitting element having a relatively short peak wavelength. The third phosphor is excited by light emitted from any of the solid state light emitting elements.
