摘要 |
Provided are an illumination apparatus employing an auxiliary light source and a projection system therewith. The illumination apparatus includes a main light source unit for emitting white light, and an auxiliary light source unit for introducing auxiliary light of a predetermined wavelength band to a space in which the light intensity of the main light source unit is low to increase the intensity of the white light. The illumination apparatus can uniformly control a spatial light intensity distribution and a band light intensity distribution, and enlarge a color reproduction area and provide a high quality image with high luminous efficiency.
