Abstract:
The present invention relates to an LED illuminant module and lighting apparatus and, more specifically, to a high color rendering D50/D65 standard LED illuminant module and lighting apparatus, which has both high color rendering properties and excellent metamerism index characteristics by using a high color rendering LED and an ultraviolet LED. An illuminant module according to an embodiment of the present invention comprises: at least one ultraviolet light-emitting diode (LED) device having a peak emission wavelength of 300 nm-400 nm; and at least one first white light-emitting diode (LED) device having an average color rendering index of 90% or higher, wherein the first white light-emitting diode (LED) device is a light-emitting diode (LED) device which comprises a first LED chip having an excitation wavelength of 440 nm-460 nm, and a first phosphor layer excited at the excitation wavelength of the first LED chip to emit light, and the first phosphor layer comprises: a first phosphor having a peak emission wavelength of 440 nm-499 nm; a second phosphor having a peak emission wavelength of 500 nm-580 nm; and a third phosphor having a peak emission wavelength of 600 nm-699 nm.
