Provided are a projector and a lens adjusting module. The projector includes a main body, a light source disposed on the main body and providing an illumination beam, a light valve disposed on the main body and converting the illumination beam into an image beam, a projection lens movably disposed on the main body in a moving direction and projecting the image beam, and the lens adjusting module. The lens adjusting module includes a driven member connected to the projection lens and having a limiting flange, a limiting structure connected to the main body, and a rotating member screwed to the driven member and rotating to drive the driven member and the projection lens to move in a moving direction. The limiting structure is adapted to stop the limiting flange to limit a movement range of the driven member in the moving direction.

Projector and lens adjusting module

The invention provides a light source module and a projection device. The projection device includes the light source module, an optical engine module, a heat dissipation module, and a projection lens. The light source module includes a light emitting unit, a carrier, and a noise reduction unit. The light emitting unit is configured for providing a lighting beam. The carrier is configured for fixing the light emitting unit and has an opening, and the light source of the light emitting unit is aligned with the opening. The noise reduction unit is configured to surround at least a part of the light emitting unit. The optical engine module includes a light valve located on a transmission path of the lighting beam and is configured for converting the lighting beam into an image beam. The light source module is located between the optical engine module and the heat dissipation module.

A fixing base for fixing an optical element and disposing at least two elastic members is provided. The fixing base includes a fixing groove and an elastic member fixing groove. The elastic members abut against the elastic member fixing groove to provide the elastic members with a push force toward the optical element, so that the optical element abuts against the fixing groove. An opening direction of the fixing groove and an opening direction of the elastic member fixing groove are nonparallel to the optical axis of the optical element, and the elastic members and the optical element are respectively disposed in the elastic member fixing groove and the fixing groove along a direction nonparallel to the optical axis. The invention also provides a projection device including the fixing base. The fixing base provided by the invention can accurately and easily fix the optical element.

Fixing base and projection device

A projector, an optical engine module, an image resolution enhancement device and a driving method are provided. The projector includes an illumination device, an optical engine module and a projection lens. The optical engine module is configured with the image resolution enhancement device configured to enhance a resolution of a projection light, and the image resolution enhancement device is adapted to enhance the image resolution by two times or four times.

A fine adjustment mechanism includes a first frame, a carrying portion and a first connecting portion. The first frame has a first opening. The carrying portion is adapted to assemble outside an optical element for fixing it. The carrying portion has a carrying plate disposed in the first opening and extends from the first opening towards a side of the first frame. The first connecting portion is located in the first opening and connected between the carrying plate and the first frame. The first connecting portion is capable of generating an elastic torsion around the axis in a first direction. By using the theorem of elastic torsion, the present invention makes the carrying portion rotate around the axis of the first connecting portion only and is able to avoid the offset problem occurred at the intersection of the axes of the carrying portion and the first connecting portion during adjusting.
