Abstract
A projection apparatus including an actuator, a light source, and a projection lens is provided. The light source is disposed on the actuator and is capable for emitting light beams sequentially. The actuator is capable for driving the light source so as to change the transmission paths of the light beams. The projection lens is disposed on the transmission paths of the light beams. The volume of the projection apparatus can be reduced since the light source is directly disposed on the actuator.
