  • Publication number: 20060203206
    Abstract: A projector includes a first LED module having a first LED projecting a ray of one of three primary colors of light and a first substrate mounting the first LED. A second LED module includes second and third LEDs projecting the other two colors of the three primary colors and a second substrate mounting the second and third LEDs. An optical illuminating system uniformly focuses and projects red, green and blue rays emitted from the first to third LEDs. A display unit forms an image by modulating the light projected from the optical illuminating system according to image information. An optical projecting system enlargingly projects the image formed by the display unit onto a screen. A cooling apparatus cools and therefore keeps the first to third LEDs at approximately the same temperature.
