摘要:
An illumination device includes a first illumination section having a first light source which emits white light and a first optical system for applying, with a first directional characteristic, the white light emitted from the first light source, and a second illumination section having a second light source which emits light of a color different from the color of the light from the first light source, and a second optical system for applying the light emitted from the second light source with a second directional characteristic such that the light is applied to a second application area contained in and smaller than a first application area based on the first directional characteristic.
摘要:
A light source apparatus is designed in accordance with an object, and following elements and phosphors are disposed in a casing, a first light emitting element that emits a light in a first irradiation mode, which is selected so that a light emission band has a portion that overlaps a first-specific-band, a first phosphor selected so as to include the first-specific-band in an excitation band and include a second-specific-band in a fluorescence-emission-band, a second phosphor selected so that an excitation intensity compared with the first phosphor is low in the first-specific-band, and high in a second-fluorescence-excitation-band at a short wavelength side in a second-irradiation-band and a fluorescence-emission-band includes the second-irradiation-band other than the second-fluorescence-excitation-band, and a second light emitting element that emits a light in a second irradiation mode, which is selected so that a light emission band is included in the second-fluorescence-excitation-band.
