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.

Abstract: A light source module includes a light-emitting device, a wavelength conversion device and a polarization and color separation unit. The light-emitting device provides an excitation beam including a first portion beam having a first polarization direction. The wavelength conversion device includes a first wavelength conversion area and a polarization conversion area. When the first portion beam irradiates the first wavelength conversion area, the first portion beam is converted into a first color beam. When the first portion beam irradiates the polarization conversion area, the first polarization direction of the first portion beam is converted to a second polarization direction. The polarization and color separation unit is disposed between the wavelength conversion device and the light-emitting device, and transmits the first portion beam with the first polarization direction, and reflects the first portion beam with the second polarization direction and the first color beam to the same direction.
