Abstract: A projection apparatus includes a projection unit, a base and a pivoting member. The projection unit includes a light source, a light valve and a lens. The light source provides an illumination beam, the light valve converts the illumination beam into an image beam, and the lens projects the image beam. The base is connected to the projection unit and has at least one first stopping portion. The pivoting member is pivoted to the base and has at least one second stopping portion. The pivoting member is adapted to connect to an external power supply device, the base and the pivoting member are adapted to relatively rotate so as to adjust an angle of the projection image.

Abstract: A lens structure includes a lens barrel, a frame, a first lens module, a second lens module, and an elastic sleeve. The frame leans against a rear end of the lens barrel. A first gap is provided between the lens barrel and the frame. The first lens module includes a first side exposed outside the lens barrel and a second side arranged in a front end of the lens barrel. A second gap is provided between the lens barrel and the first lens module. The second lens module includes a third side arranged in the rear end of the lens barrel and a fourth side exposed outside the frame. The elastic sleeve sleeved on the lens barrel includes a first end extending to the frame to completely cover the first gap and a second end extending to a portion of the first lens module to completely cover the second gap.

Abstract: A projection device including a housing, an optical engine, and a power connector is provided. The housing has a front end portion, a rear end portion opposite to the front end portion, and a projection opening. The optical engine is disposed within the housing and includes a projection lens, a first light-emitting element, and a second light-emitting element. The projection lens is adapted to output an image beam through the projection opening. The first light-emitting element and the second light-emitting element are respectively thermally coupled to a first coupling portion and a second coupling portion of the housing. The housing has a heat separation for separating the first coupling portion and the second coupling portion. The power connector is connected to the rear end portion.
