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: An adapter assembly and a projection device are provided. The projection device includes a device body, an illumination system, a light valve, the adapter assembly, and a projection lens. The light valve is disposed in the device body to convert the illuminating beam provided by the illumination system into an image beam. The projection lens includes a plurality of protruding claws that surround a circumferential surface of a main body and protrude along the radial direction. The adapter assembly includes a first ring member, a rotating plate, and a second ring member sequentially disposed along the axial direction of the adapter assembly. When the projection lens is assembled to the adapter assembly, the rotating plate rotates to limit the protruding claws within a limiting assembly space formed by the first ring member and the second ring member to lock the projection lens to the device body.

Abstract: 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.
