    摘要: In a light wavelength conversion member 16, a translucent 30 encapsulates a yellow phosphor 32 and a blue phosphor 34. The yellow phosphor 32 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 (34) 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 32 and the blue phosphor 34 and the translucent member 30 is less than or equal to 0.2.
