    摘要: A projection lens module and a projector are provided. The projector includes an optical engine and a projection lens module. The optical engine includes a casing, a light source, a light valve, and a prism, where the light source, the light valve, and the prism are disposed in the casing. The light source emits an illumination beam to the light valve. The light valve modulates the illumination beam to generate an image beam and projects the image beam to the projection lens module. The prism is disposed on an optical path of the image beam. The projection lens module is connected to the casing of the optical engine and is configured to project the image beam. The projection lens module includes a projection lens and a smooth picture actuator, where the smooth picture actuator is fixed to the projection lens and is located outside the optical engine.

    摘要: A transparent rotating device comprising a shaft, a transparent rotating assembly and a motor is provided. The transparent rotating assembly includes at least one first transparent sheet and at least one second transparent sheet that are annularly and alternatively arranged around a shaft. A motor is connected to the shaft, wherein the first transparent sheet and the second transparent sheet sequentially enter the transmission path of the image beam. The angle at which the first transparent sheet is inclined with respect to the shaft is different from the angle at which the second transparent sheet is inclined with respect to the shaft. The image beam penetrates the first transparent sheet to be deflected and transmitted to a first position, and the image beam penetrates the second transparent sheet to be deflected and transmitted to a second position.

    摘要: The invention provides a projection device which includes a rotating module and an imaging module. The rotating module is assembled on a mounting surface and includes a rotating part and an assembling part which are integrally formed. The rotating part is parallel to the mounting surface, and the assembling part is perpendicular to the mounting surface. The imaging module is assembled on the assembling part of the rotating module. When the rotating module rotates by taking an axis perpendicular to the mounting surface as an axial center, the rotating module drives the imaging module to rotate so as to change a projection direction of the imaging module. The projection device of the invention adjusts the projection direction without using a tool.
