Abstract:
1. A white light-emitting device using a fluorescent fiber, comprising: a blue semiconductor light-emitting element for emitting an excitation light; and an optical fiber having a first side end face and a second side end face, the excitation light emitted from the blue semiconductor light-emitting element being made incident to the first side end face to be guided to the second side end face, the optical fiber comprising: a core containing therein a phosphor for emitting wavelength conversion lights by being excited by the excitation light supplied from the blue semiconductor light-emitting element; and a cladding member having a light emission surface in its peripheral surface, at least a part of optically multiplexed lights, which are obtained by optically multiplexing the wavelength conversion lights and the excitation light, being emitted through the light emission surface.
