Illumination system and projection apparatus comprising the same

摘要

An illumination system and a projection apparatus are provided. The projection apparatus comprises the illumination system and an imaging system for forming an image. The illumination system comprises a plurality of light source modules, a first wavelength transformer, an optical apparatus and a first angle selective film. The light source modules are used for generating a plurality of light beams. The first wavelength transformer is disposed at a predetermined position. The optical apparatus is disposed between the light source modules and the first wavelength transformer for focusing the light beams to the predetermined position. The first angle selective film is disposed on the first wavelength transformer. The first wavelength transformer is disposed between the first angle selective film and the optical apparatus. The first angle selective film is used for angle-selectively filtering the light beams passing through the first wavelength transformer.
