摘要： The invention aims at providing controllable parameters that are correlated with special color rendering index R9, and at providing a white-light emitting semiconductor device having a high R9 value obtained through optimization of such parameters. The white-light emitting semiconductor device is provided with a phosphor as a light-emitting material and with a light-emitting semiconductor element as an excitation source of the phosphor. The phosphor includes at least a green phosphor and a wide-band red phosphor. In the white light-emitting semiconductor device, an intensity at wavelength 640 nm of an emission spectrum which has been normalized with respect to luminous flux is 100-110% of the intensity at wavelength 640 nm of a spectrum of standard light for color rendering evaluation which has been normalized with respect to luminous flux.

Each of the light components (blue, green, and red) is based on a light-emitting semiconductor element and/or a phosphor that absorbs light emitted by a light-emitting semiconductor element and emits light through wavelength conversion. The outputted light has a spectrum which has a maximum wavelength in the range of 615-645 nm, and the intensity at a wavelength of 580 nm of the outputted light, which has been normalized with respect to luminous flux, is 80-100% of the intensity at a wavelength of 580 nm of standard light for color rendering evaluation, which has been normalized with respect to luminous flux.
