    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.
