Patent ID: 8337400

Claim:
An illumination device comprising a light source including a first light source that emits light having a first wavelength, a second light source that emits light having a second wavelength different from the first wavelength, and a third light emitting device that has or is coated with one or more phosphors which are excited by the light emitted from the first light source to emit first fluorescent light having an emission wavelength different from the first wavelength an energy of fluorescence light of the third light emitting device when the one or more phosphors of the third light emitting device are excited by the light having the second wavelength and having a certain energy is equal to or less than 1/10 of that of fluorescence light of the third light emitting device when the one or more phosphors of the third light emitting device are excited by the light having the first wavelength and having the certain energy.
