Abstract:
1. A white-light emitting device comprising: a frame having a first cup-shaped recess and a second cup-shaped recess whose openings are adjacent to each other; a first light source formed inside the first cup-shaped recess; a first emitting section formed inside the first cup-shaped recess; a second light source formed inside the second cup-shaped recess; a second emitting section formed inside the second cup-shaped recess; and a wall included in the frame, the wall separating the first cup-shaped recess and the second cup-shaped recess from each other; wherein the first emitting section contains a first luminescent material which is excited by light that the first light source emits to emit light including a wavelength component longer than that included in the light that the first light source emits, wherein the second emitting section contains a second luminescent material which is excited by light that the second light source emits, and which may be excited by light the first luminescent material emits, to emit light including a wavelength component longer that that included in the light that the first luminescent material emits, wherein the wall prevents at least a part of the light that the first emitting section emits from entering the second emitting section and the wall reflects the light the first light source emits and the light that the second light source emits, and wherein the white-light emitting device emits white-light synthesized so as to contain the light emitted by the first emitting section and the second emitting section.
