Title: (EN) LIGHT-EMITTING DEVICE
(KO) 발광 장치
Abstract: front page image
(EN) According to an embodiment, a light-emitting device comprises: a light-emitting element which emits light having a peak wavelength of 425 nm to 465 nm; a first phosphor which emits light having a peak wavelength of 485 nm to 530 nm; a second phosphor which emits light having a peak wavelength longer than that of the first phosphor; and a third phosphor which emits light having a peak wavelength longer thatn that of the second phosphor. Also, when the peak wavelength of the light-emitting element is 0 (nm) and the peak wavelength of the first phosphor is 1 (nm), 30=1-0=70 is satisfied. COPYRIGHT KIPO 2015
(KO) 실시 형태의 발광 장치는, 425㎚ 이상 465㎚ 이하의 피크 파장의 광을 발광하는 발광 소자와, 485㎚ 이상 530㎚ 이하의 피크 파장의 광을 발광하는 제1 형광체와, 제1 형광체보다 긴 피크 파장의 광을 발광하는 제2 형광체와, 제2 형광체보다 긴 피크 파장의 광을 발광하는 제3 형광체를 구비한다. 그리고, 발광 소자의 피크 파장을 λ(㎚), 제1 형광체의 피크 파장을 λ(㎚)로 하는 경우에, 30≤λ-λ≤70이다. 0 1 1 0
