Abstract
A light emitting device containing a semiconductor light emitting component and a phosphor, the phosphor is capable of absorbing a part of light emitted by the light emitting component and emitting light of a wavelength different from that of the absorbed light, is provided. A straight line connecting a point of chromaticity corresponding to a spectrum generated by the light emitting component and a point chromaticity corresponding to a spectrum generated by the phosphor is substantially along a black body radiation locus in a chromaticity diagram.

15. A light emitting device comprising:
-
a semiconductor light emitting component; and a phosphor capable of absorbing a part of light emitted by the light emitting component and emitting light of wavelength different from that of the absorbed light, wherein a straight line connecting a point of chromaticity along an emission wavelength corresponding to a spectrum generated by the light emitting component and a point of chromaticity along an emission wavelength corresponding to a spectrum generated by the phosphor corresponds to white light substantially along a black body radiation locus in a chromaticity diagram.
