Projection apparatus and array lens module
First Claim
1. A projection apparatus, comprising:
- an optical engine base;
a light source, assembled to the optical engine base;
a light valve, assembled to the optical engine base;
a projection lens, assembled to the optical engine base; and
an array lens module, comprising;
a frame body, fixed to the optical engine base, having at least one first positioning hole and at least one second positioning hole;
a first array lens, having at least one first positioning pillar, the first positioning pillar being inserted into the first positioning hole of the frame body to fix the first array lens to the frame body; and
a second array lens, having at least one second positioning pillar, the second positioning pillar being inserted into the second positioning hole of the frame body to fix the second array lens to the frame body, wherein 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.

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.
