    摘要： A fluorescent member includes: a wavelength converter including an incidence part on which a light of a light source is incident and an output part from which a converted light subjected to wavelength conversion as a result of excitation by an incident light is output; and a reflecting part provided in at least a portion of a surface of the wavelength converter. The wavelength converter is comprised of a material whereby a degree of scattering of the light of the light source incident via the incidence part and traveling toward the output part is smaller than in the case of a polycrystalline material.

    摘要： An apatite crystal is a single crystal expressed by a general formula (M2)5(PO4)3X. In this formula, M2 indicates at least one type of element selected from the group consisting of bivalent alkaline-earth metals and Eu, and X indicates at least one type of element or molecule selected from the group consisting of halogen elements and OH. And the single crystal is of a tubular shape. The outer shape of the apatite may be a hexagonal prism. The shape of an opening of a hole formed in the upper surface or lower surface of the hexagonal prism may be a hexagon.

    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： In a light emitting module, a red phosphor is contained in a second phosphor layer so that the wavelength of a second phosphor layer after the wavelength conversion is longer than that of a first phosphor layer. And a blue phosphor and a yellow-green phosphor are contained in the first phosphor layer. The first phosphor layer is formed in an illumination area of light emitted from an LED chip, and the first phosphor layer converts the wavelength of the light from the LED chip and emits the wavelength-converted light from an emission surface. A part of the second phosphor layer is formed in a non-direct area where no light is illuminated from the LED chip and where light is illuminated from the first phosphor layer. The part of the second phosphor layer formed in the non-direct illumination area converts the wavelength of the light emitted from the first phosphor layer.
