Abstract: A light source module includes a first light-emitting unit, a second light-emitting unit, a first dichroic mirror, and a wavelength conversion unit. The first light-emitting unit emits a first color light. The second light-emitting unit emits a second color light. The first dichroic mirror allows the first color light to transmit through and has a passing area. The passing area allows the second color light to pass through. The wavelength conversion unit includes a substrate and a phosphor layer disposed on the substrate. The phosphor layer converts the first color light transmitting through the first dichroic mirror into a third color light, and reflects and scatters the second color light passing through the passing area. The first dichroic mirror reflects the second color light reflected by the wavelength conversion unit and the third color light.
