Abstract

See full text

An illumination system includes a coherent light source, a first light-combining element, an optical wavelength conversion module, and a first auxiliary light source. The coherent light source emits a coherent light beam. The first light-combining element is disposed on a transmission path of the coherent light beam. The light wavelength conversion module is disposed on a transmission path of the coherent light beam transmitted from the first light-combining element and converts the coherent light beam into a first converted light beam, and reflects the first converted light beam back to the first light-combining element. The first auxiliary light source emits a first auxiliary light beam which is transmitted to the first light-combining element along the transmission path of the coherent light beam. The first light-combining element combines the first auxiliary light beam and the first converted light beam. A projection apparatus is also provided.
