Abstract
An illumination system comprises an exciting light source, a phosphor wheel, a first lens, a first reflector, and a light uniforming element. The exciting light source emits an excitation beam. In a first time sequence, the phosphor wheel reflects the excitation beam to the first reflector, the first reflector reflects the excitation beam to the first lens and the excitation beam passes through the first lens and transmits to the light uniforming element. In a second time sequence, the phosphor wheel converts the excitation beam to a conversion beam, the conversion beam from the phosphor wheel passes through the first lens and transmits to the first reflector, the first reflector reflects the conversion beam to the first lens, the conversion beam passes through the first lens and transmits to the light uniforming element, the excitation beam and the conversion beam, sequentially and respectively transmits to the light uniforming element.
