The light source module may include a plurality of light-emitting units, at least two optical units, and at least two light conversion units. Light from a first light-emitting unit exits as first exiting light processed by a first and second optical units, light from a second light-emitting unit forms first converted light processed by the first optical unit and converted by a first light conversion unit, light from a third light-emitting unit forms second converted light processed by the second optical unit and converted by a second light conversion unit. The second converted light exits as second exiting light processed by the second and first optical unit, and the first converted light serves as third exiting light processed by the first optical unit and is combined with the first and second exiting lights to form a first beam having a first, second, and third wavelength.
