    • An illumination system and a projection system capable of enhancing light efficiency and contrast. The projection system includes a display panel from which light incident to a projection lens unit is controlled according to the rotation of a plurality of micromirrors and an asymmetric stop which adjusts an angle of effective light incident from the display panel. The illumination system emitting light to the projection system includes: one or more light source units each including a single or an array of light emitting devices and having a light exit surface with an aspect ratio different from an aspect ratio of the display panel; and an aspect ratio adjusting unit adjusting the aspect ratio of the light such that the aspect ratio of the light exit surface of each of the light source units can be equal to the aspect ratio of the display panel.
    • 一种能够提高光效和对比度的照明系统和投影系统。 投影系统包括:显示面板,根据多个微镜的旋转,入射到投影透镜单元的光被控制,以及调整从显示面板入射的有效光的角度的非对称止挡。 向投影系统发射光的照明系统包括:一个或多个光源单元,每个光源单元各自包括单个或阵列的发光器件,并且具有不同于显示面板的纵横比的纵横比的光出射表面; 以及纵横比调整单元,其调节光的纵横比,使得每个光源单元的光出射面的纵横比可以等于显示面板的纵横比。
