Patent ID: 8076847

Claim:
A light emitting device comprising: a package having a first concave portion and a second concave portion, the first concave portion being bored on a bottom of the second concave portion in an inner direction opposite to a direction toward the face of observing luminescence to form a step on the bottom of the second concave portion; light sources comprising a first light source mounted in the first concave portion and a second light source mounted in the second concave portion; a first phosphor layer disposed in the first concave portion the first phosphor layer absorbing at least a portion of a light emitted from the first light source and emitting a first light having a wavelength longer than the light emitted from the first light source; a second phosphor layer which absorbs at least a portion of a light emitted from the first light source and the light emitted from the second light source and which emits a second light having a wavelength longer than the light emitted from the second light source; wherein a peak wavelength of the first light is longer than a peak wavelength of the second light, and wherein the first light emitted from the first phosphor is diffused by the second phosphor without being absorbed.
