Abstract
A light-emitting device includes first and second light-emitting elements, an optical member, and a wavelength conversion member. The optical member includes an optical action layer configured to reflect or transmit light in accordance with a wavelength of the light. The optical action layer is configured to reflect first emission light emitted from the first light-emitting element and second emission light emitted from the second light-emitting element. The wavelength conversion member is configured to receive the first emission light reflected by the optical action layer of the optical member, to convert a wavelength of the first emission light, and to emit a wavelength-converted light having a converted wavelength. The optical action layer of the optical member is configured to transmit the wavelength-converted light. The optical member is arranged so that the wavelength-converted light and the second emission light are emitted from an upward-facing surface of the optical action layer.
