The color illuminating system includes a light source, a spiral lens disc that periodically scrolls light by rotational movement, and an optical unit that isolates light beams of different wavelengths from white light emitted from the light source and guides the isolated light beams to enter at least two effective regions of the spiral lens disc. The projection type image display apparatus includes the color illuminating system, an image forming unit that generates images using scrolling light from the spiral lens disc, and a projection lens unit that enlarges and projects the images formed by the image forming unit on a screen.

摘要： A highly efficient projection system is provided, including a light source, a color separator, a scrolling unit, a light valve, a projection lens unit, and a polarization conversion system. The color separator separates an incident beam according to color. The scrolling unit includes at least one lens cell and converts a rotation of the lens cell into a rectilinear motion of an area of the lens cell through which light passes so the incident beam is scrolled. 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. The polarization conversion system is installed between the color separator and the light valve and converts the incident beam into a beam with a single polarization.

The optical splitter splits light emitted from the light source according to wavelength. The at least one scrolling unit has at least one lens cell. The lens cell has an incident side and an emitting side and divides incident light into light beams. The rotation of the lens cell causes a rectilinear motion of the light beams, thereby scrolling incident light. The light emitted from the light source is separated into color beams by the optical splitter and the scrolling unit, and the color beams are focused on the light valve. The light valve processes incident light according to an input image signal in order to form a color image.
