Abstract
There is provided an LED light source whose chromaticity can be adjusted easily without changing its outer shape and suffering damage in the process of chromaticity adjustment. An LED light source includes an LED device, a fluorescent material that absorbs and wavelength-converts a portion of light emitted from the LED device to emit light from itself, a sealing material that includes the fluorescent material and that is disposed around the LED device, and light scattering sections that are formed at a portion of a surface of the sealing material and scatter a portion of the light emitted from the LED device for adjusting chromaticity of the LED light source, and a chromaticity adjustment method for such LED light source.
