Patent ID: 8721088

Claim:
A lens array module, comprising: a light incident surface; a light emitting surface opposite to the light incident surface; a plurality of first lens surfaces arranged on the light incident surface to form into an array; and a plurality of second lens surfaces arranged on the light emitting surface to form into an array, wherein a center of curvature of each of the first lens surfaces located at two opposite sides of a first reference point on the light incident surface deviates away from the first reference point in a direction parallel to a first reference axis, and a center of curvature of each of the second lens surfaces located at two opposite sides of a second reference point on the light emitting surface deviates toward the second reference point in a direction parallel to the first reference axis, wherein an area of each of the second lens surfaces adjacent to the second reference point in a direction parallel to the first reference axis is greater than an area of each of the second lens surfaces away from the second reference point in the direction parallel to the first reference axis.
