Abstract

A light source module includes a light-collecting lens, a first light source unit, a first light-combining element, a second light source unit, a second light-combining element, and a third light source unit. The first, second, and third light source units are respectively configured to emit a first, second, and third light beams. The first and second light-combining elements are configured to respectively reflect the first and second light beams to the light-collecting lens disposed in a transmission path of the third light beam. An optical axis of the light-collecting lens is parallel to a first direction, and an optical axis of the first light source unit is parallel to a second direction. The first and second light source units and the first and second light-combining elements are disposed in an alternating manner in a third direction perpendicular to the first and second directions. A projection device is also provided.
