  • Patent number: 9568813
    Abstract: A projector includes a light source that emits a light beam, an illumination lens unit, a display device, a projection lens unit, a field lens, and a reflection member. The illumination lens unit shapes and focuses the light beam into an illumination light beam. The display device modulates the illumination light beam and forms an image. The projection lens unit projects the image on a screen. The field lens has a positive refractive power for focusing the illumination light beam on the display device, a first lens surface on which the illumination light beam is incident, and a second lens surface on which the image formed by the display device is incident. The reflection member changes an illumination light beam path into a direction of the field lens. The first lens surface reflects a portion of the illumination light beam into a path that avoids the projection lens unit.

  • Patent number: 9435996
    Abstract: An illumination optical system for a beam projector includes: a light source; a color conversion unit having at least one fluorescent substance layer that reflects a light from the light source or converts the light emitted from the light source to a wavelength-converted light; and a dichroic mirror that causes the light emitted from the light source to be incident on the color conversion unit. Lights reflected or emitted by the conversion unit and having different wavelengths are incident on a display panel through the same path. In the illumination optical system, a light emitted from one light source can be processed to produce red, green and blue lights which can be in turn incident on the display panel through the same optical path of the light reflected or emitted by the conversion unit.
