    摘要: The present invention seeks to realize a small etendu illumination optical system, a longer operating life and a higher brightness. The illumination optical system comprises: a laser light source that generates an excitation light; a fluorescent substance that generates a fluorescent light in response to the excitation light, a light tunnel that outputs the excitation light input at one end thereof to the fluorescent substance from the other end thereof, and that outputs the fluorescent light generated by the fluorescent substance from the one end thereof; and a mirror that is placed within a light path between the laser light source and the light tunnel, and that reflects the fluorescent light, the mirror having an aperture formed thereon that allows the excitation light to pass through.

    摘要: An illumination apparatus includes a fluorescence unit, laser light irradiation means, and a beam integration unit. The fluorescence unit has a plurality of phosphors, in which the colors of fluorescence generated due to excitation differ, arranged in different regions. The laser light irradiation means irradiates laser light onto the regions of each color of the fluorescence unit while changing the position at which the laser light strikes the fluorescence unit. The beam integration unit integrates fluorescence from each region of the fluorescence unit on a display panel.

    摘要: A safe, highly bright projector is to be implemented. A projector directs a light beam from a light source (101) to an image modulating device (105), and magnifies and projects an image formed at the image modulating device (105) through a zoom lens (102). This projector has a light transmitting window (103) movably disposed in front of the surface of the light outgoing side of the zoom lens (102) along the optical axis. The projector further has a window position control unit (108) to control the position of the light transmitting window (103) so as not to change the light beam region that appears on the outer surface of the light transmitting window (103) as the focal length of the zoom lens (102) is varied.
