Projection device

A projection device, comprising at least one projection module, at least one reflecting element, and at least one adjusting structure,

• the at least one projection module having at least one optical axis, the at least one projection module being adapted to provide a projection beam, wherein the projection beam is transmitted along a light transmission path to a projection target to form a projection image;
• the at least one reflecting element being disposed between the at least one projection module and the projection target and located on the optical axis and having a reflecting surface, wherein the reflecting surface is adapted to reflect the projection beam to the projection target;
• the at least one adjusting structure being connected to the projection module and the reflecting element, wherein the adjusting structure is adapted to drive the projection module and the reflecting element to rotate along a second axis such that the projection image rotates.
