Title:
HIGH COLOR RENDERING D50/D65 STANDARD LED ILLUMINANT MODULE AND LIGHTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/050260
Kind Code:
A1
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 300nm-400nm; 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 440nm-460nm, 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 440nm-499nm; a second phosphor having a peak emission wavelength of 500nm-580nm; and a third phosphor having a peak emission wavelength of 600nm-699nm.
