PURPOSE: A projection system is provided to effectively transfer the uniform amount of light emitted from light emitting diodes to a display element. CONSTITUTION: A projection system comprises a lighting unit, a display element, and a projection unit. The lighting unit comprises first, second, and third light sources(210,220,230) and a color composition unit(100). The first, second, and third light sources emit first, second, and third lights. The color composition unit composes the emitted first, second, and third lights using first and second color filters(110,120). The display element receives the light from the lighting unit and generates an image light. The projection unit projects the image light to a screen. |
