  • Patent number: 9121576
    Abstract: In a light wavelength conversion unit, a light wavelength conversion member is placed on the emission surface of a semiconductor light-emitting element. The light wavelength conversion member converts the wavelength of blue light, which has emitted from the semiconductor light-emitting element and entered from an incident surface, so as to emit yellow light and then emits the yellow light from an emission surface. A light reflection layer is provided on a lateral face in the surface of the light wavelength conversion member. Here, the lateral face excludes the incident surface and the emission surface. The light wavelength conversion member is roughened such that an average roughness Ra of the lateral face is 0.5 ?m or above.
