发明名称 Light emitting apparatus
摘要 An object of the present invention is to provide a light emitting apparatus that allows it to easily control the driving of LED and has high color rendering properties. The light emitting apparatus comprises the first light emitting device 108a that has first peak emission wavelength in blue region and emits blue light, the fluorescent material 140 that is excited by the light from the first light emitting device 108a and emits red light, the second light emitting device 108b that has second peak emission wavelength which is longer than the first peak emission wavelength and is shorter than peak emission wavelength of the fluorescent material 140, and the second light emitting device 108b that emits green light of second peak emission wavelength which is longer than the first peak emission wavelength, so as to emit light generated by blending of blue light, green light and red light to the outside.
