Imaging lens module and mobile terminal

摘要

An imaging lens module includes an imaging lens assembly and a first optical component. The imaging lens assembly has an optical axis and includes a lens element. The lens element includes an effective optical portion, which is non-circular and disposed on a center of the lens element. The first optical component has a non-circular opening hole. The effective optical portion of the lens element of the imaging lens assembly is corresponded to the non-circular opening hole of the first optical component.

1. An imaging lens module, comprising:
an imaging lens assembly comprising at least one lens element, wherein the lens element comprises an effective optical portion disposed on a center of the lens element; a first optical component being a barrel and comprising:
a side wall, which is closed-shape; andan end wall connected to one end of the side wall and having a circular opening hole, which is a stop of the imaging lens assembly; and at least one second optical component having a non-circular opening hole, wherein the second optical component and the imaging lens assembly are disposed in the first optical component, and the non-circular opening hole of the second optical component is corresponded to the circular opening hole of the first optical component; wherein a line distance between any two points of a peripheral edge of the non-circular opening hole of the second optical component through a center of the non-circular opening hole of the second optical component is m2AA′, a minimum line distance between two points of the peripheral edge of the non-circular opening hole of the second optical component through the center of the non-circular opening hole of the second optical component is m2BB′, a maximum line distance between two points of the peripheral edge of the non-circular opening hole of the second optical component through the center of the non-circular opening hole of the second optical component is m2CC′, an angle between the line distance m2AA′ of the second optical component and the minimum line distance m2BB′ of the second optical component is K2AB, an angle between the maximum line distance m2CC′ of the second optical component and the minimum line distance m2BB′ of the second optical component is K2CB, and the following conditions are satisfied: m2BB′≦m2AA′|K2CB|, wherein |K2AB| and |K2CB| are both smaller than or equal to 90 degrees.
