Abstract:
1. A light source module, comprising: a light-emitting device, providing an excitation beam, wherein the excitation beam comprises a first portion beam, and the first portion beam has a first polarization direction; a wavelength conversion device, disposed on a transmission path of the first portion beam, wherein the wavelength conversion device is suitable for rotating and comprises: a first wavelength conversion area and a polarization conversion area, wherein when the wavelength conversion device rotates, the first portion beam of the excitation beam alternately irradiates the first wavelength conversion area and the 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, and 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; and a polarization and color separation unit, disposed between the wavelength conversion device and the light-emitting device, wherein the polarization and color separation unit 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 a same direction.
