ABSTRACT:
The present invention is directed to the provision of an LED light source that can easily adjust its chromaticity and a chromaticity adjustment method for such an LED light source. More specifically, the invention provides a chromaticity adjustment method for an LED light source having an LED device, a phosphor which absorbs a portion of light emitted from the LED device and emits light by wavelength conversion, and a resin material containing the phosphor and disposed so as to enclose the LED device, wherein an ink coating layer is disposed on a surface of the resin material in order to adjust chromaticity; the invention also provides an LED light source adjusted in such a manner.
