Abstract:
1. A light emitting device comprising: a plurality of light emission groups, each of the light emission groups including multiple kinds of light emission units with different emission colors; a driver which drives the light emission units in said each of the light emission groups; and a plurality of cover members detachable from each other, each of the cover members corresponding to one of the light emission groups, wherein each of the cover members is commonly provided for the multiple kinds of light emission units in said one of the light emission groups, wherein the multiple kinds of light emission units in said each of the light emission groups include solid state light emitting elements of the same kind, and wavelength converters which cover the solid state light emitting elements, respectively, and convert wavelengths of lights emitted from the solid state light emitting elements into different wavelengths from each other, wherein said each of the cover members contains a correction phosphor for correcting a chromaticity of light obtained by mixing lights emitted from the light emission units in said one of the light emission groups, to a predetermined chromaticity wherein each of the wavelength converters includes: wherein the bowl-shaped member and the solid material are in close contact with each other, and wherein the solid material has a refractive index which is identical to a refractive index of the bowl-shaped member.
