Abstract
A light emitting apparatus includes a light emitting device, fixedly situated at a first position, to emit light at a wavelength, a first phosphor, fixedly situated at a second position, to radiate light with a first spectral characteristic out of the light emitting apparatus in response to irradiation by the light at the wavelength, and a second phosphor, fixedly situated at a third position, to radiate light with a second spectral characteristic out of the light emitting apparatus in response to irradiation by the light at the wavelength. An optical coupling mechanism is included to optically couple the light emitting device to the first phosphor and to optically decouple the light emitting device from the second phosphor in a first operating mode, and optically couple the light emitting device to the second phosphor in a second operating mode.
