Abstract
A projection device includes a light source module for emitting an illumination beam, an optical engine module for receiving the illumination beam and forming an image beam, and a projection lens for receiving and projecting the image beam to an outside of the projection device. The optical engine module includes first and second shells coupled in a first direction, an elastic sealing member and electronic components. The shells form an accommodation space in which the electronic components are disposed. The elastic sealing member has opposite first and second surfaces. The first surface has an engagement groove in which a portion of the first shell is engaged. The second shell abuts against the second surface. Signal transmission components of the electronic components are disposed through the elastic sealing member to pass through the shells.
