Abstract
An illumination system includes a coherent light source, a first light-combining device, an optical wavelength conversion module, and a first auxiliary light source. The coherent light source emits a coherent light beam. The first light-combining device 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 device 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 device. The first auxiliary light source emits a first auxiliary light beam which is transmitted to the first light-combining device. The first light-combining device combines the first auxiliary light beam and the first converted light beam. A projection apparatus and a method for driving the illumination system are also provided.
