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.
