摘要： In a projection display apparatus, laser beams that are emitted from light sources and that are reflected and two-dimensionally scanned by scanning mirrors are modulated by a light bulb, and are then magnified through a projection lens to be projected. The F numbers of the scanning mirrors are smaller than that of the projection lens. The irradiation regions of the laser beams that are reflected by the scanning mirrors with respect to the light bulb are reduced by a lens.

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.
