  • Publication number: 20140140071
    Abstract: In a light wavelength conversion member, a translucent member encapsulates a yellow phosphor and a blue phosphor. The yellow phosphor is excited by light ranging from near-ultraviolet light to short-wavelength visible light whose dominant wavelength is 350 nm to 480 nm and then emits yellow light. The blue phosphor is excited by light ranging from near-ultraviolet light to short-wavelength visible light whose dominant wavelength is 350 nm to 480 nm and then emits blue light. The difference in refractive index between each of the yellow phosphor and the blue phosphor and the translucent member is less than or equal to 0.2.
