<p>A light emitting device having a wavelength converting member for absorbing light from a pumping light source and converting its wavelength. Assuming a wavelength where the light from the pumping light source has a maximum energy intensity is a first wavelength, a wavelength where the light from the wavelength converting member has a maximum energy intensity is a second wavelength, a wavelength between the first and second wavelengths where emission spectrum of the light emitting device has a minimum energy intensity is a third wavelength, and a wavelength of 650 nm is a fourth wavelength, the ratio of energy intensity between the first and third wavelengths is 100:15-150, and the ratio of energy intensity between the first and fourth wavelengths is 100:45-200.</p> |
