Abstract
A projection apparatus includes an optical engine base, a light source, a light valve, a projection lens, and an array lens module. The light source, the light valve, and the projection lens are installed to the optical engine base. The array lens module includes a frame body fixed to the optical engine base, a first array lens, and a second array lens. One of the first array lens and the frame body has a first positioning hole while the other one has a first positioning pillar inserted into the first positioning hole. One of the second array lens and the frame body has a second positioning hole while the other one has a second positioning pillar inserted into the second positioning hole. A light beam emitted by the light source passes through the first array lens, the second array lens, and the light valve sequentially to reach the projection lens.
