The invention discloses an X-type adjustment module, comprising a cover, a first frame, a second frame, a first light transmitting element, a second light transmitting element, a first adjustment member, and a second adjustment member. The first frame is pivotally connected to the cover. The second frame is pivotally connected to the first frame and intersects the first frame. The first light transmitting element is fixed in the first frame. The second light transmitting element is fixed in the second frame and intersects the first light transmitting element. The first adjustment member passes through the cover and abuts against the first frame. The second adjustment member passes through the cover and abuts against the second frame. A transmission path of a light beam is controlled by adjusting disposition angles of the first light transmitting element and the second light transmitting element to avoid excessive concentration of light energy.

X-type adjustment module, and light combining device and projector using the X-type adjustment module

An adjustment mechanism configured to fix and adjust a light integration rod including an outer cylinder member, an inner cylinder member and a first adjustment member. The outer cylinder member has a first open end, a second open end and a cylinder wall, wherein the cylinder wall has a first opening and a first locking portion protruding outward. The inner cylinder member is configured to accommodate the light integration rod. The inner cylinder member is disposed in the outer cylinder member, a first outer surface of the inner cylinder member has a first protruding portion, wherein the first protruding portion passes through the first opening and protrudes from the outer cylinder member, and is opposite to the first locking portion. The first adjustment member is connected to the first locking portion and the first protruding portion, and configured to move the inner cylinder member back and forth.

Adjustment mechanism and projection device

A projection apparatus includes a light source, an optical engine module, and a lens module. The lens module includes a plate having at least one through hole, a lens fixed to the plate, at least one slide assembly disposed between the plate and an optical engine housing of the optical engine module, and a position adjusting device including a movable guide member and at least one guide pillar. The plate is movably disposed on the optical engine housing through the slide assembly. The movable guide member is movably disposed between the plate and the optical engine housing. The guide pillar is disposed on the movable guide member and passes through the through hole. When the movable guide member is forced to move towards an axial direction, the guide pillar drives the plate to move on the slide assembly along the axial direction relative to the optical engine housing.

Projection apparatus and lens module

An optical element adjusting apparatus configured to support an optical element includes an adjusting base, a fixed base and locking elements. The adjusting base includes a first through hole disposed on a center of gravity of the adjusting base, a second through hole and a third through hole. An extension direction of a first straight line passing through the first through hole and the second through hole is different from an extension direction of a second straight line passing through the first through hole and the third through hole. The fixed base includes coupling holes corresponding to the first, second, third through holes. The locking elements pass though the first, second, third through holes respectively and are coupled to the coupling holes to couple the adjusting base to the fixed base. The adjusting base includes a support side away from the fixed base to support the optical element.

Optical element adjusting apparatus and projector using the same

A lamp position adjustment device includes a bottom frame, a lamp holder, and a lamp mount. The lamp holder is disposed on the bottom frame for supporting the lamp, and the lamp mount is disposed between the lamp holder and the bottom frame. The lamp mount includes a base portion, a first side portion and a second side portion that are respectively connected to two opposite sides of the base portion, a first positioning mechanism, and a second positioning mechanism. The first positioning mechanism is disposed on the base portion to enable the lamp mount to be slidably connected to the bottom frame, and the second positioning mechanism is disposed on the first side portion and the second side portion to enable the lamp mount to be slidably connected to the lamp holder.
