ABSTRACT:
An illumination system includes at least one light emitting device to emit a light beam having different wavelengths, a focusing lens to condense the light beam emitted from the light emitting device, and a waveguide having an incident surface inclined at a predetermined angle upon which the light beam condensed by the focusing lens is incident. A projection system includes at least one light emitting device to emit a light beam having the different wavelengths, a focusing lens to condense the light beam emitted from the light emitting device, a waveguide having an incident surface inclined at a predetermined angle on which the light beam is condensed by the focusing lens, a display device to form an image by processing the light beam passing through the waveguide according to an input image signal, and a projection lens unit to magnify the image formed by the display device and to project the magnified image toward a screen.
