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.
