    Abstract: A projection apparatus includes a casing with an opening, a light-emitting unit in the casing and emitting a first projection beam, and a reflective component in the casing and on a transmission path of the first projection beam. The first projection beam reflected by the reflective component becomes a second projection beam projected out via the opening along a projection direction. The light-emitting unit includes a projection lens with an optical axis between a center of the reflective component and the opening of the casing.
