A blue light emitting element is mounted on a bottom of a case body. A cover member covers the blue light emitting element. Fluorescent material is mixed in the cover member for converting wavelength of light emitted from the blue light emitting element to adjust chromaticity of the light, and luminance reducing material for adjusting the luminance of the light is mixed in the cover member.
