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 devicethat has first peak emission wavelength in blue region and emits blue light, the fluorescent materialthat is excited by the light from the first light emitting deviceand emits red light, the second light emitting devicethat 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, and the second light emitting devicethat 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.
