    摘要： 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.

    摘要翻译： 在光波长转换构件中，半透明构件包封黄色荧光体和蓝色荧光体。 黄色荧光体由近紫外光到主波长为350nm至480nm的短波长可见光的光激发，然后发出黄光。 蓝色荧光体被从近紫外光到主波长为350nm至480nm的短波长可见光的光激发，然后发出蓝色光。 黄色荧光体和蓝色荧光体与透光性部件的折射率的差别小于或等于0.2。
