    Abstract: The optical system of a projection display apparatus. The projection display apparatus includes a light source, a prism, a light valve, and a projection lens. A light beam emitted from the light source impinges into the prism and passes through the first surface of the prism directly to illuminate the light valve which is placed near the first surface and parallels the first surface. By the reflection of the light valve, the light beam impinges into the first surface again, and illuminates a total internal reflection surface with an incidental angle large than the critical total reflection angle, so as to reflect the light beam out of the second surface of the prism and impinge to projection lens to form an image. Therefore, the optical system can increase the transmission and decrease the number of components, and reduce its overall volume.

    Abstract: An illumination system, a projection device, and an illumination method are provided. The illumination system includes a polarized light source, a polarization switching element, a beam splitting element, a wavelength conversion element, a reflective element, and a wave plate. The polarized light source emits a polarized light beam with a first color. The polarization switching element switches a polarized direction of the polarized light beam at different time points. The beam splitting element separates polarized light beams having different polarized directions. The wavelength conversion element converts the polarized light beam having a first polarized direction to a converted light beam. The reflective element reflects the polarized light beam having a second polarized direction to form a reflected light beam. The beam splitting element combines the converted light beam and the reflected light beam comes from the wave plate disposed between the beam splitting element and the reflective element.
