Abstract:
A white light emitting device includes a substrate, a first light emitting diode configured to emit first blue light having a peak intensity at a wavelength within the range of 445 nm to 455 nm, a second light emitting diode configured to emit second blue light having a peak intensity at a wavelength within the range of 465 nm to 495 nm, and a wavelength conversion unit configured to convert portions of the first blue light and the second blue light, and to provide white light formed by a combination of the converted portions of the first blue light and the second blue light with unconverted portions of the first blue light and the second blue light. The wavelength conversion unit includes a first wavelength conversion material configured to emit first light having a peak intensity at a wavelength within the range of 520 nm to 560 nm, and a second wavelength conversion material configured to emit second light having a peak intensity at a wavelength within the range of 600 nm to 645 nm.

Claim (Index 14):
A white light emitting device comprising:\n a first light emitting diode configured to emit first blue light having a peak intensity at a wavelength within the range of 445 nm to 455 nm; a second light emitting diode configured to emit second blue light having a peak intensity at a wavelength within the range of 465 nm to 490 nm; a first wavelength conversion material configured to convert at least portions of the first blue light and the second blue light to emit first light having a peak intensity at a wavelength within the range of 520 nm to 560 nm; and a second wavelength conversion material configured to convert at least portions of the first blue light and the second blue light to emit second light having a peak intensity at a wavelength within the range of 600 nm to 645 nm, the second wavelength conversion material having at least one red phosphor selected from among (Sr,Ca)AlSiN 3 :Eu, CaAlSiN 3 :Eu, and any combination thereof, wherein a combination of an unconverted portion of the first blue light, an unconverted portion of the second blue light, the first light, and the second light produces a white light, and wherein, in a spectrum of the white light, peak intensities of the unconverted portion of the first blue light and the unconverted portion of the second blue light range from 50% to 110% and from 53% to 110% of a peak intensity of the second light respectively, the sum of the peak intensities of the unconverted portions of the first blue light and the second blue light ranges from 140% to 180% of the peak intensity of the second light, and the maximum intensity in a wavelength range of 530 nm to 550 nm ranges from 70% to 90% of the peak intensity of the second light.
