Abstract
An illumination system including an excitation light source, a wavelength conversion element and a filter element is provided. The excitation light source is used for emitting an excitation beam. The wavelength conversion element has a wavelength conversion region. When the wavelength conversion region is cut into a transmission path of the excitation beam, the wavelength conversion region is excited by the excitation beam and emits a converted beam. A reference plane is perpendicular to the transmission path of the converted beam and is angled such that an acute angle is formed between the reference plane and the filter wheel which is disposed on a transmission path of the converted beam coming from the wavelength conversion element. The filter element allows a part of the converted beam to penetrate so as to output at least one color beam, and reflects another part of the converted beam.
