摘要： An illumination system includes an exciting light source, a first lens set, a dichroic element, a wavelength-converting element and a beam splitter. The exciting light source emits an excitation beam. The dichroic element reflects the excitation beam to the first lens set. The first lens set has an optical axis. The excitation beam is incident into the first lens set in a direction parallel to the optical axis and passes through the first lens set. The beam axis of the excitation beam is noncoaxial with the optical axis. The wavelength-converting element has a reflective region and a wavelength-converting region. The wavelength-converting region converts the excitation beam into a converted beam, which passes through the dichroic element and the beam splitter. The reflective region reflects the excitation beam to the first lens set and the beam splitter. The beam splitter splits the excitation beam into two branch excitation beams.

摘要： The light source device and the projection display apparatus include a solid-state light source unit, a dichroic mirror, a fluorescent plate, a first wave plate, and a multi-reflection mirror. The solid-state light source unit emits first and second linearly polarized light rays at a predetermined ratio, the first and the second linearly polarized light rays being orthogonal to each other. The dichroic mirror separates the first and the second linearly polarized light rays, and combines blue light with yellow light. The fluorescent plate emits the yellow light to the dichroic mirror when the fluorescent plate is excited by the first linearly polarized light ray separated by the dichroic mirror. The first wave plate converts the second linearly polarized light ray separated by the dichroic mirror, into circularly polarized light. The multi-reflection mirror reflects the circularly polarized light to the dichroic mirror as the blue light.

摘要： A projection apparatus including an illumination system, a light valve, an optical actuation element and a projection lens is provided. The illumination system provides an illumination beam. An image display surface of the light valve includes a first region and a second region. First pixels of the first region convert the illumination beam into first sub-image beams. Second pixels of the second region convert the illumination beam into second sub-image beams. A transmission path of one of the first sub-image beams in the optical actuation element is a first transmission path. A transmission path of one of the second sub-image beams in the optical actuation element is a second transmission path. A length of the first transmission path is smaller than a length of the second transmission path. In this way, the projection apparatus has good image quality.
