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 1):
A white light emitting device comprising:\n a substrate; a first light emitting diode disposed on the substrate, the 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 disposed on the substrate, the 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 applied to the first light emitting diode and the second light emitting diode, the wavelength conversion unit configured to convert portions of the first blue light and the second blue light and to provide a white light formed by the 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, wherein 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, and wherein in a spectrum of the white light, a peak intensity of the unconverted portion of the second blue light is equal to 50% or more of a peak intensity of the unconverted portion of the first blue light, and the maximum intensity in a wavelength band of 520 nm to 560 nm is between 70% and 160% of the peak intensity of the unconverted portion of the second blue light.
