Abstract:
A wavelength converting member comprising a first wavelength converting layer containing: a first fluorescent material having a light emission peak wavelength in a range of 620 nm or more and 660 nm or less; a second fluorescent material having a light emission peak wavelength in a range of 510 nm or more and 560 nm or less; and a resin, wherein the average particle diameter, as measured according to a Fisher Sub-Sieve Sizer method, of the first fluorescent material is in a range of 2 μm or more and 30 μm or less, wherein the second fluorescent material comprises a β-SiAlON fluorescent material, the circularity of the β-SiAlON fluorescent material is 0.7 or more, and the volume average particle diameter, as measured according to a laser diffraction scattering particle size distribution measuring method, of the β-SiAlON fluorescent material is in a range of 2 μm or more and 30 μm or less, and wherein the thickness of the first wavelength converting layer is in a range of 50 μm or more and 200 μm or less.

Claim (Index 5):
The wavelength converting member according to  claim 1 ,\n wherein the first fluorescent material comprises: a Mn 4+ -activated fluoride fluorescent material; a fluorescent material containing an Eu 2+ -activated silicon nitride containing at least one element selected from Sr and Ca, and Al; and at least one fluorescent material containing an Eu 2+ -activated aluminum nitride containing at least alkaline earth metal element and at least one alkali metal elements, and wherein the second fluorescent material further comprises: a chlorosilicate-based fluorescent material; a Mn 2+ -activated aluminate fluorescent material containing at least one alkaline earth metal element selected from the group consisting of Ba, Sr, and Ca; and at least one \u03b3-AlON fluorescent material.
