Zusammenfassung:	A projection device includes a first light source, a second light source, a driving unit, a reflecting member and a light integrator. The driving unit and the first light source are located at opposite sides of a second light axis of the second light source. The driving unit and the second light source are located at opposite sides of a first light axis of the first light source. The driving unit drives the reflecting member to move between a first position and a second position. When the reflecting member is located at the first position, the first light source emits a first light along the first light axis to the light integrator. When the reflecting member is located at the second position, the second light source emits a second light along the second light axis and the reflecting member reflects the second light to the light integrator.
