<p>PURPOSE: A video projector is provided to increase the intensity of radiation of monochromatic lights by amplifying a specific wavelength in a visible ray band, thereby increasing the intensity of radiation and improving the efficiency of using light, and improve the chromatic purity by moving a center wavelength of the specific wavelength within a predetermined range. CONSTITUTION: A lamp(310) emits a white beam. An intensity increasing unit(320), fluorescent substance, outputs a beam having a specific wavelength among the emitted white beam after increasing the intensity of radiation of the beam. A color wheel(330) receives the white beam from the intensity increasing unit for dividing the white beam into a plurality of monochromatic lights. A digital micromirror device panel(350) reflects the monochromatic lights at a predetermined angle.</p> |
