Patent ID: 8309375

Claim:
A method for manufacturing a light emitting device comprising: preparing a light emitting component having an active layer of a semiconductor, said active layer comprising a gallium nitride based semiconductor containing indium and being capable of emitting a blue color light having a spectrum with a peak wavelength within the range from 420 to 490 nm; preparing a phosphor capable of absorbing a part of the blue color light emitted from said light emitting component and emitting a yellow color light having a broad emission spectrum comprising a peak wavelength existing around the range from 510 to 600 nm and a tail continuing beyond 700 nm, wherein selection of said phosphor is controlled based on an emission wavelength of said light emitting component; and combining said light emitting component and said phosphor so that the blue color light from said light emitting component and the yellow color light from said phosphor are mixed to make a white color light, wherein a chromaticity point of the white color light is on a straight line connecting a point of chromaticity of the blue color light and a point of chromaticity of the yellow color light, and wherein a content of said phosphor in said light emitting device is selected to obtain a desired chromaticity of the white color light.
