Abstract
A light emitting device including multiple kinds of light emission units with different emission colors; a driver which drives the light emission units; and a cover member which is commonly provided for the multiple kinds of light emission units. The multiple kinds of light emission units 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. Further, the cover member contains a correction phosphor for correcting a chromaticity of light obtained by mixing lights emitted from the light emission units, to a predetermined chromaticity.
