Abstract

A light source module including first and second light sources, first and second wavelength conversion units, first and second light-splitting units is provided. The first light source emits a first light having a first wavelength. The first wavelength conversion unit converts at least one portion of the first light into a first converted light having a second wavelength. The second light-splitting unit allows the light having the first wavelength to travel through and reflects the light having the second wavelength. The second light source emits a second light having the first wavelength. The second wavelength conversion unit converts at least one portion of the second light into a second converted light having the second wavelength. The first light-splitting unit disposed between the first and the second wavelength conversion units reflects the light having the first wavelength and allow the light having the second wavelength to travel through.
