Abstract:
1. A light emitting device comprising: a light emitting element; a first phosphor which emits a light by being excited by a light emitted from the light emitting element; and a second phosphor which emits a light by being excited by the light emitted from the light emitting element and/or the light emitted from the first phosphor, wherein the light emitting element, the first phosphor, and the second phosphor are configured such that, on a chromaticity diagram, an inclination angle of a straight line, connecting chromaticity coordinates of the light emitted from the first phosphor and chromaticity coordinates of the light emitted from the light emitting element is substantially equal to an inclination angle of an isotemperature line of light of a predetermined color temperature produced by mixing the light emitted from the light emitting element, the light emitted from the first phosphor and the light emitted from the second phosphor.
