Abstract
A light source module including an exciting light source, a wavelength conversion module, and a light combining unit is provided. The exciting light source is capable of providing an exciting light beam. The wavelength conversion module includes at least one wavelength conversion reflecting portion and a wavelength conversion portion which cut into the transmission path of the exciting light beam alternately. When the wavelength conversion portion cuts into the transmission path of the exciting light beam, part of the exciting light beam which passes through the wavelength conversion portion is a first color light beam and another part of the exciting light beam is converted into a second color light beam by the wavelength conversion portion. The color of the second color light beam is different from that of the exciting light beam. A projection apparatus is also provided.
