摘要：
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.
