A lens array set for a projection apparatus is provided. The lens array set comprises a first lens array and a second lens array. The first lens array has a plurality of first lens units which are rectangle-shaped and a side thereof that defines the first direction. The second lens array, which is parallel with the first lens array, has a plurality of second lens units which has a rectangle shape and a side thereof that defines the second direction. Each of the second lens units is set correspondingly to each of the first lens units, and the center of each second lens unit and the center of each first lens unit are coaxial. A rotation angle is substantially defined between the first direction and the second direction depending on the difference between the rectangle shapes of the first and the second lens units. When adopting the present invention in the projection apparatus, the light source efficiently provides light for the micro-display. |
