摘要

LED lighting device in which color-mixed light according to a mixture of a blue optical emission spectrum according to the emission from an LED element, a red optical emission spectrum according to the emission from a red phosphor, and a green optical emission spectrum according to the emission from a green phosphor is emitted, wherein in the spectrum for the emitted color-mixed light, letting the relative spectral area for the principal-wavelength peak of the blue optical emission spectrum be A_Band the peak emission intensity be I_B, letting the relative spectral area of the green optical emission spectrum be A_Gand the peak emission intensity be I_G, and letting the relative spectral area of the red optical emission spectrum be A_Rand the peak emission intensity be I_R, then I_BI_G, I_BI_R, A_B≦A_G, A_B≦A_R, and A_B/(A_R+A_G)≦0.4.
