Abstract
A projection device including at least one projection module and at least one adjusting structure is provided. The projection module has at least one optical axis. The projection module is adapted to provide an image beam. The image beam is transmitted along a light transmission path to a projection target and forms a projection image. The adjusting structure is connected to the projection module. The adjusting structure is adapted to drive at least a part of the projection module to rotate along the optical axis such that the projection image rotates.

A projection device, comprising at least one projection module 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 an image beam, wherein the image beam is transmitted along a light transmission path to a projection target and forms a projection image;
- the at least one adjusting structure being connected to the projection module, wherein the adjusting structure is adapted to drive at least a part of the projection module to rotate along the optical axis such that the projection image rotates,
- wherein the projection module comprises a light source, a light valve, and a lens set, the light source is adapted to provide an illumination beam, the light valve is located on a transmission path of the illumination beam and adapted to convert the illumination beam to the image beam, the lens set is located on a transmission path of the image beam and adapted to transmit the image beam to an outside of the projection module,
- wherein the adjusting structure is connected to the projection module, the adjusting structure is adapted to drive at least a part of the projection module to rotate along a first axis or move along a first direction such that the projection image moves horizontally, and the adjusting structure is adapted to drive at least a part of the projection module to rotate along a second axis or move along a second direction such that the projection image moves vertically,
- wherein the first axis, the second axis, and the optical axis are perpendicular to each other.
A projection device, comprising at least one projection module 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 an image beam, wherein the image beam is transmitted along a light transmission path to a projection target and forms a projection image;
