Abstract
A light source module includes first to third light sources respectively providing first, second and third lights, first and second wavelength conversion layers, first and second auxiliary light sources respectively providing first and second auxiliary lights, and a dichroic member. The first wavelength conversion layer is excited by the first light and the first auxiliary light from different sides to generate a first conversion light. The second wavelength conversion layer is excited by the second light and the second auxiliary light from different sides to generate a second conversion light. The dichroic member allows the first and second auxiliary lights to transmit therethrough and reflects the first and second conversion lights. The third light transmits through the dichroic member. The first and second conversion lights and the third light are different in wavelength ranges and combined to form an illumination light.
