Abstract
A projector includes an outer casing and a projection module. The outer casing has a front end surface, a projection opening, and at least one heat dissipation opening. The projection opening and the at least one heat dissipation opening are located at the front end surface. The projection module is disposed in the outer casing and includes a light source module configured to provide an illumination beam, a light valve configured to convert the illumination beam to an image beam, and a projection lens protruding from the front end surface and is configured to project the image beam out of the outer casing through the projection opening. The projection module is configured to rotate relative to the outer casing to change a projection direction of the image beam and may be embedded in a ceiling and present a better appearance, and the projection direction of the projector is less restricted.
