Light source optical system capable of using converted light and non-converted light from wavelength conversion element, light source apparatus using the same, and image display apparatus

A light source optical system guides blue light from a light source to a fluorescent body. The fluorescent body converts the blue light into fluorescent light and emits the fluorescent light and non-converted light. Further, the light source optical system includes an optical element having a first...

Zusammenfassung:	A light source optical system guides blue light from a light source to a fluorescent body. The fluorescent body converts the blue light into fluorescent light and emits the fluorescent light and non-converted light. Further, the light source optical system includes an optical element having a first region for guiding the blue light to the fluorescent body and a second region for guiding the fluorescent light and the non-converted light to lens cells. The blue light is incident on the first region, and the fluorescent light and the non-converted light are incident on the first region and the second region of the optical element. An area of the first region and an area of each lens cell of the lens cells as viewed along directions of optical axes of the lens cells have a predetermined relationship.
