WAVELENGTH CONVERTING MEMBER AND LIGHT SOURCE DEVICE |
摘要 |
A wavelength converting member radiates light having a wavelength different from that of laser light introduced into the wavelength converting member. The wavelength converting member has a phosphor layer that contains a phosphor therein. The phosphor layer has a laser light incidence surface capable of receiving the laser light. The wavelength converting member also has a high-refractive layer that is bonded to an opposite surface of the phosphor layer to the laser light incidence surface thereof. A refractive index of the high-refractive layer is higher than a refractive index of the phosphor layer. The high-refractive layer has concaves on at least either the bonding surface where the high-refractive layer is bonded to the phosphor layer or a light extraction surface that is opposite the bonding surface.
