A novel configuration of a light-emitting apparatus that can emit white
light, in which a primary light source composed of a group III nitride
compound semiconductor is used in combination with a secondary light
source including a fluorescent material which emits light of a green
luminescent color when the fluorescent material is excited by light
emitted from the primary light source. A tertiary light source for
emitting red light may be further used in combination with the primary
and secondary light sources.
