Abstract: The disclosure provides a light valve module comprising a main casing, a light valve element, a heat dissipation structure and a supporting component. The light valve element is connected to the main casing. The heat dissipation structure is connected to the main casing and is in contact with the light valve element. The supporting component comprises an extending portion and a supporting portion. An end of the extending portion is connected to the main casing. The supporting portion is formed on another end of the extending portion. A part of the heat dissipation structure is suspended above the extending portion and adapted to be supported by the supporting portion.

Abstract: A lens module includes a lens fixing device and a base. The lens fixing device includes: a lens holder, a lens, a plurality of elastic sheets, and a shielding sheet. The lens is assembled on the lens holder. The plurality of elastic sheets is locked on the lens holder and pressed around an edge of the lens. The shielding sheet is arranged on at least one of the plurality of elastic sheets, and is located on a transmission path of an excitation light beam to prevent the excitation light beam from directly irradiating the at least one of the plurality of elastic sheets. The lens holder is assembled on the base.

Abstract: An optical element adjustment device includes a casing base, an optical element, a bearing element, and a first adjustment module. The optical element is movably disposed in the casing base. The bearing element includes an outer frame bearing the optical element and a shaft portion protruding from the outer frame and penetrating from the casing base. The first adjustment module is disposed on the shaft portion. A screw shank is sleeved on the shaft portion and penetrates from the casing base. The first adjustment element is screwed to the screw shank and abuts against the casing base. A limiting element protrudes from a side surface of the shaft portion and is located next to the screw shank. The first elastic element is disposed between the screw shank and the outer frame, such that the screw shank leans closely to the limiting element.

Abstract: The disclosure provides an adjustable optical module, including an optical element, a carrier, a frame, two first positioning members, a base, and two second positioning members. One of the carrier and the frame includes two first pivot shafts that protrude from both sides and extend along a first axis, and the other includes two first pivot holes. The two first pivot shafts are located in the two first pivot holes, respectively. One of the frame and the base includes two second pivot shafts that protrude from both sides and extend along a second axis, and the other includes two second pivot holes. The two second pivot shafts are located in the two second pivot holes, respectively. The disclosure provides a projector, including a light source module, a light valve, a projection lens, and the foregoing adjustable optical module.

Abstract: Provided are an adjustable optical module and a projector including the same. The adjustable optical module includes an optical element; a carrier; a frame; a base; a first adjusting assembly including a first driving member, a first adjusting member, and a first rotating member; and a second adjusting assembly including a second driving member, a second adjusting member, and a second rotating member. The first adjusting member is adjusted to drive a first boss of the first driving member to move, the first rotating member being correspondingly driven to rotate, thereby pushing the carrier to rotate around a first axis relative to the base. The second adjusting member is adjusted to drive a second boss of the second driving member to move, the second rotating member being correspondingly driven to rotate, thereby pushing the frame to rotate around a second axis relative to the base.
