| 英文摘要 | A light emitting device comprises a first unit and a second unit, the first unit comprising: a first excitation light source (10) comprising a laser element emitting blue wavelength band excitation light; a first wavelength converting member (30) comprising at least one type of fluorescent material and which absorbs at least a portion of a first excitation light emitted from the first excitation light source (10), converts the wavelength, and releases light with a wavelength longer than the first excitation light; and a first light guide (20) which has a refractive index in the center region of the cross-section which is higher than the refractive index of the surrounding region and which transmits the first excitation light emitted from the first excitation light source; and the second unit comprising: a second excitation light source (10) comprising a laser element which emits excitation light with a wavelength band shorter than the blue wavelength band excitation light emitted by the laser element; a second wavelength converting member (30) which is similar of the above; and a second light guide (20) which is similar of the above. |
