Abstract

An illumination system includes a light integration rod and a light source module. The light integration rod has a light-in end, a light-out end opposite to the light-in end, and phosphor distributed between the light-in end and the light-out end. The light source module is configured to provide a laser beam to enter into the light integration rod through the light-in end thereof. The phosphor is used to convert the laser beam into a first color beam to form an illumination beam. The illumination beam then emits out from the light integration rod through the light-out end thereof. A projection apparatus using the aforementioned illumination system is also provided.
