Abstract
A projection apparatus and a light condensing module are provided. The light condensing module condenses and deflects an incident beam. The light condensing module includes a curving incident surface, a curving outgoing surface and a reflection surface. The curving incident surface receives the incident beam. The curving outgoing surface is disposed on a transmission path of the incident beam from the curving incident surface. The reflection surface is disposed on the transmission path of the incident beam, and located between the curving incident surface and the curving outgoing surface. A ray of the incident beam propagates through the curving incident surface along the optical axis of the curving incident surface, and emits out from the curving outgoing surface along a direction inclined to the optical axis of the curving outgoing surface.
