ABSTRACT:
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 device108athat has first peak emission wavelength in blue region and emits blue light, the fluorescent material140that is excited by the light from the first light emitting device108aand emits red light, the second light emitting device108bthat has second peak emission wavelength which is longer than the first peak emission wavelength and is shorter than peak emission wavelength of the fluorescent material140, and the second light emitting device108bthat 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.
