A light source module adapted to be used in a projection apparatus includes a first LED device, a second LED device, and a light switching element. The first LED device emits a first light beam along a first light path during a first time period. The second LED device emits a second light beam along a second light path during a second time period. The light switching element is disposed at an intersection of the first light path and the second light path for permitting one of the first light beam along the first light path and the second light beam along the second light path to be transmitted along a third light path.
