WHITE LIGHT-EMITTING DEVICE USING FLUORESCENT FIBER |
摘要 |
A white light-emitting device using a fluorescent fiber includes a blue semiconductor light-emitting element ( 2 ) for emitting an excitation light (a), and an optical fiber ( 3 ) having one side end face and the other side end face, the excitation light (a) emitted from the blue semiconductor light-emitting element ( 2 ) being made incident to the one side end face to be guided to the other side end face. The optical fiber ( 3 ) includes a core containing therein a phosphor for emitting wavelength conversion lights by being excited by the excitation light (a) received from the blue semiconductor light-emitting element ( 2 ), and a cladding member ( 3 B) 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.
