Claim Text:
1. An LED lighting device including: a blue LED element emitting light having an optical emission peak in the 420 nm to 490 nm wavelength region; a green phosphor that by being excited by the emission from said blue LED element emits light having an optical emission peak in the 495 nm to 530 nm wavelength region; and a red phosphor that by being excited by the emission from said blue LED element emits light having an optical emission peak in the 595 to 680 nm wavelength region; the LED lighting device emitting color-mixed light according to a mixture of the blue emission spectrum according to the optical emission from said blue LED element, the green emission spectrum according to the optical emission from said green phosphor, and the red emission spectrum according to the optical emission from said red phosphor; wherein letting the relative spectral area of the blue optical emission spectrum be A are satisfied.
