A lens module includes a first base, a lens assembly assembled on the first base, a second base stacked on the first base, a first adjustment member, and a second adjustment member. The first base has at least one first rib structure extending along a second axis, and at least one second rib structure extending along a first axis. The first adjustment member is movably engaged with the first rib structure along the first axis. The second adjustment member is movably engaged with the second rib structure along the second axis. When the first base moves along the first axis, the second adjustment member avoids the second rib structure. When the first base moves along the second axis, the first adjustment member avoids the first rib structure. A projection device is also provided.

Lens module and projection device

A projection device and a light source module having a light transmitting region and a non-light transmitting region, and including a base, a light-emitting element, a collimating lens, an adhesive, and a light-shielding member are provided. The light-emitting element is disposed on the base at a position corresponding to the light transmitting region for providing a light beam. The collimating lens is disposed on the base. The adhesive is disposed on the base at a position corresponding to the non-light transmitting region, and located between the collimating lens and the base to bond the collimating lens and the base. The light-shielding member is disposed in the non-light transmitting region and covers a part of the collimating lens. A projection of the light-shielding member and a projection of the adhesive on the base at least partially overlap. The light source module and the projection device have good reliability.

The disclosure provides an optical module comprising a first frame, a second frame, a pillar and an optical component. The first frame has an adjustment portion, and the adjustment portion has a guiding slot. The second frame is rotatably connected to the first frame along the first axis. The pillar is connected to the second frame and is disposed through the guiding slot. The pillar is configured to be subjected to force and swing in the guiding slot to drive the second frame to rotate around the first axis. The optical component is disposed on the second frame. In addition, a projector with the optical module is also disclosed, and the rotation angle of the optical component can be accurately adjusted by the optical module.

Optical module and projector

A lens module includes a carrier, a framework, and an optical lens disposed on the framework. The carrier has an inner surface including a contact surface. The framework contacts the contact surface and is configured with a guiding lever disposed in a guiding recess formed across the inner surface. When the guiding lever is moved in the guiding recess, the framework is rotated on the carrier about an optical axis, and the framework and the optical are moved on the carrier along the optical axis. A projection apparatus includes an illumination system, a light valve, and a projection lens, and the illumination system includes the lens module. The lens module and the projection apparatus may be used to adjust the focusing position of the light beam passing through the optical lens to a proper position, and improve the projection quality of the projection apparatus.
