Abstract:
A light emitting device includes a first wavelength converter that contains a first phosphor that absorbs at least part of primary light radiated by a radiation source and converts the primary light absorbed into secondary light, and a second wavelength converter that contains a second phosphor that absorbs at least part of the secondary light and converts the secondary light absorbed into tertiary light. The lifetime of fluorescence emitted from the second phosphor is longer than the lifetime of fluorescence emitted from the first phosphor, and the light density of the secondary light, with which the second wavelength converter is irradiated, is lower than the light density of the primary light, with which the first wavelength converter is irradiated.

Claim (Index 1):
A light emitting device comprising:\n a radiation source that radiates laser light as primary light; a first wavelength converter that contains a first phosphor that absorbs at least part of the primary light radiated by the radiation source and converts the primary light absorbed into secondary light; and a second wavelength converter that contains a second phosphor that absorbs at least part of the secondary light emitted by the first wavelength converter and converts the secondary light absorbed into tertiary light, wherein at least the first phosphor is sealed with an inorganic material, the light emitting device emits output light containing the primary light, the secondary light, and the tertiary light, the secondary light contains a larger amount of long-wavelength component than the primary light, the tertiary light contains a larger amount of long-wavelength component than the secondary light, a lifetime of fluorescence emitted from the second phosphor is longer than a lifetime of fluorescence emitted from the first phosphor, and light density of the secondary light, with which the second wavelength converter is irradiated, is lower than light density of the primary light, with which the first wavelength converter is irradiated.
