Abstract
An illumination system including an excitation light source, a wavelength conversion module, a light splitting module and a light homogenizing element is provided. The light splitting module has a transfer region and a light splitting region, an excitation beam incident to the wavelength conversion module is converted into a wavelength converted beam by a wavelength conversion region, and is reflected by the reflection region, and the excitation beam coming from the wavelength conversion module is split into a first and a second sub-excitation beams by the light splitting region, and the first sub-excitation beam and the second sub-excitation beam form an excitation combination beam. The light homogenizing element uniforms the excitation combination beam and the wavelength converted beam, where an angle of the excitation combination beam incident to the light homogenizing element is 0.25 times larger than an angle of the wavelength converted beam incident to the light homogenizing element.
