The invention is to provide a white light-emitting semiconductor device having improved reproducibility regarding bright red. The invention relates to a white light-emitting semiconductor device which outputs light comprising a blue light component, a green light component, and a red light component, wherein a source of the blue light component comprises a light-emitting semiconductor element and/or a first phosphor that absorbs the light emitted by a light-emitting semiconductor element and emits, through wavelength conversion, light including the blue light component, a source of the green light component comprises a second phosphor that absorbs the light emitted by a light-emitting semiconductor element and emits, through wavelength conversion, light including the green light component, and a source of the red light component comprises a third phosphor that absorbs the light emitted by a light-emitting semiconductor element and emits, through wavelength conversion, light including the red light component. The outputted light has a spectrum which has a maximum wavelength in the range of 615-645 nm, and an intensity at a wavelength of 580 nm of the spectrum of the outputted light which has been normalized with respect to luminous flux is 80-100% of an intensity at a wavelength of 580 nm of the spectrum of standard light for color rendering evaluation which has been normalized with respect to luminous flux. |
