摘要： A projection device includes: first light sources each emitting a first light; a collimator lens that converts the first lights into parallel light beams; a condensing optical system that receives the parallel light beams and emits concentrated light beams; and an optical element having an incident surface through which the concentrated light beams enters the optical element. The condensing optical system is configured so that when a light beam parallel to an optical axis of the condensing optical system is incident on the condensing optical system, the light beam is concentrated at a position on the axis on the incident surface. The parallel light beams are incident at different positions of the condensing optical system while approaching the axis. Emitting positions of the light beams on the condensing optical system and incident positions of the light beams on the incident surface are opposite each other with respect to the axis.
