LIGHT-EMITTING DEVICE AND LIGHTING APPARATUS HAVING SAME

WIPO Patent Application WO/2021/112554

A1

Provided are a light-emitting device and a lighting apparatus having same. A light-emitting device according to an embodiment is configured to generate white light and comprises: a first light-emitting diode chip having a first peak wavelength within a wavelength range of 400-420 nm; a second light-emitting diode chip having a second peak wavelength within a wavelength range of 420-440 nm; and a wavelength converter covering the first and second light-emitting diode chips and comprising a blue phosphor having a peak wavelength within a range of 450-500 nm, a green phosphor having a peak wavelength within a range of 500-600 nm, and a red phosphor having a peak wavelength within a range of 600-650 nm, wherein, if the maximum value among the spectral power distribution of the light-emitting device and the power distribution of the standard spectrum of blackbody radiation is set as 100%, the difference between the spectral power distribution of the light-emitting device and the power distribution of the standard spectrum is less than 20% with respect to each wavelength in a wavelength range of 440-640 nm.
