| 摘要 | An illumination device includes: an excitation light source that emits excitation light having a first wavelength; and a fluorescent member that includes a fluorescent substance that, when it is irradiated with the excitation light, emits light having a second wavelength longer than the first wavelength, transmits a part of the excitation light and reflects another part of the excitation light, and a first reflective film provided at a side of the fluorescent substance, which is opposite to an excitation light incidence side, the fluorescent member emitting multiplexed light including an excitation light component reflected from the fluorescent substance and the first reflective film and a light component emitted from the fluorescent substance. | ||

| 主权项 | 1. An illumination device comprising: an excitation light source configured to emit excitation light having a first wavelength range in at least a blue spectrum; and a single rotating fluorescent member configured to include a fluorescent substance in a single layer and that, when the fluorescent substance is irradiated with the excitation light, emits light having a second wavelength range in at least a red spectrum and a green spectrum, and a reflective member provided at a side of the fluorescent substance, which is opposite to an excitation light incidence side, the single rotating fluorescent member configured to emit light including at least in part a light component emitted from the fluorescent substance. | ||
