Abstract

A projection apparatus and an illumination system thereof are provided. The illumination system includes a light source device, a light homogenization device, an optical transmission module, and an optical wavelength conversion module. The light homogenization device is disposed on a transmission path of a light source beam from the light source device. The optical transmission module is disposed on a transmission path of the light source beam from the light homogenization device. The optical wavelength conversion module is disposed on a transmission path of the light source beam from the optical transmission module and is configured to convert a first portion of the light source beam into a converted light beam. The converted light beam and a second portion of the light source beam form an illumination light beam. The light homogenization device is disposed outside a transmission path of the illumination light beam.
