摘要： A light pipe for separating incident light according to color, a color illumination system adopting the light pipe, and a projection system adopting the color illumination system are provided. Since the projection system is a single-panel projection system adopting a scrolling unit, its optical configuration is simplified. Also, the light pipe of the projection system is comprised of different-sized color separation units, thus improving the color gamut and the color temperature. Further, the light pipe includes color selection polarizers, each of which changes the polarization direction of a color beam with a specific wavelength, thereby improving light efficiency.

摘要： A highly-efficient projection system is provided, including a light source, a color separator, a scrolling unit, a light valve, and a projection lens unit. The color separator separates an incident beam according to color. The scrolling unit includes at least one lens cell and converts the rotation of the lens cell into a rectilinear motion of an area of the lens cell through which light passes so that an incident beam is scrolled. The light valve includes a plurality of micromirrors independently driven according to image signals to change a reflection angle of incident light. The light valve processes a beam transmitted by the color separator and the scrolling unit according to an image signal and forms a color picture. The projection lens unit magnifies the color picture formed by the light valve and projects the magnified color picture onto a screen.

摘要： A projection system including an adjusting part, a scrolling part, and a color separating part is provided. The adjusting part adjusts the divergence angle of light emitted from a light source. The scrolling part scrolls a plurality of color bars on a light valve. The color separating part separates an incident beam, emitted from the light source and transmitted by the scrolling part, into a plurality of color beams. The adjusting part, the scrolling part, and the color separating part are sequentially arranged from the light source. Since beams of individual colors travel along a single path, the number of required optical components is reduced, thereby making the projection system compact.

摘要： A projection system including a light source, a rectilinearly reciprocating cylindrical lens array, an optical separator, a light valve, and a projection lens unit. The light source emits a beam. The rectilinearly reciprocating cylindrical lens array advances color beams along different paths upon reciprocation. The optical separator separates the beam emitted from the light source into color beams according to wavelength. The light valve receives the scrolled color beams transmitted by the cylindrical lens array and forms a color image by pixels turning on or off according to an input image signal. The projection lens unit magnifies the color image formed on the light valve and projects the magnified color image on a screen.

摘要： A highly efficient projection system and a color scrolling method are provided. In the color scrolling method, first, an optical splitter splits a beam emitted from a light source into individual color beams. Next, a rectangular light valve is disposed such that its long axis is along the direction into which the optical splitter splits the beam. Thereafter, the individual color beams are scrolled in the long axial direction of the light valve. The color scrolling in the long axial direction can increase light efficiency much more than a color scrolling performed in a short axial direction.
