incorporated by reference.
BACKGROUND
[0002] 1. Technical Field
[0003] The present disclosure relates to an imaging lens module.
More particularly, the present disclosure relates to an imaging
lens module applicable to mobile terminals.
[0004] 2. Description of Related Art
[0005] For the conventional optical lens modules used in the mobile
terminals, the appearance of the lens element is mostly
disc-shaped, and the appearance of the optical component is mostly
annular or cylindrical for the advantages of manufacturing. When
the pixels of the optical lens module are increased, the volume and
the outer diameter of the lens element and the optical component
should be enlarged, and it results in problems of non-imaging light
and poor image quality. Hence, the technique of volume shrinkage
for the optical lens modules is developed.
[0006] The conventional way to shrink the volume of the optical
lens modules is cutting the outer diameters of the lens elements
and the optical components, however, the assembly strength between
the lens elements and the optical components would be decreased.
Moreover, the optical quality and manufacturing yield rate would
also be reduced. For the optical lens modules with greater outer
diameter, the excessive stray light cannot be effectively
suppressed.
[0007] Therefore, the optical lens modules with properties of
volume shrinkage, stray light effectively suppressed and stable
quality are urgently required to the markets.

one effective optical portion, which is non-circular and disposed
on a center of the lens element 110. The non-circular effective
optical portion has several different outer diameters and is for

effective optical portion. In detail, the lens element 110 of the
embodiment of FIG. 3 can be made of plastic material and include
two effective optical portions, which are a first effective optical
portion 111 disposed on a surface toward the object side of the
lens element 110, and a second effective optical portion 112

[0082] Furthermore, in FIG. 1 and FIG. 2, the imaging lens module
can further include an image surface 700 disposed on the image side
of the imaging lens module. The imaging lens assembly can include
five lens elements, those are the lens element 110 and other four
lens elements (101-104), wherein the lens element 110 is adjacent
to the image surface 700. That is, the lens element which is
closest to the image surface 700 of the imaging lens assembly 100
is the lens element 110. The imaging lens module can further
include a second optical component 300. The second optical
component 300 can include a spacer 400, a light blocking plate 500,
and a retainer 600. Each of the spacer 400, the light blocking
plate 500, and the retainer 600 of the second optical component 300
is disposed in the first optical component 200 and has at least a
non-circular hole. The non-circular hole of the second optical
component 300 is shrunk from a circular opening hole with a fixed
diameter. The shrunk portion can be for blocking the parts of the
non-imaging light and the stray light. The specific surface of the
second optical component 300 can be processed to be coated or
obtain a matte or sandblasted appearance so as to reduce the
reflection of the light. The specific surface of the spacer 400 or
the retainer 600 can further be designed a plurality of coaxially
arranged annular projection structure so as to reduce the light
diffusing. Therefore, each of the spacer 400, the light blocking
plate 500, and the retainer 600 has the light suppression property.
Moreover, the second optical component 300 can be closer to the
non-circular opening hole 220 of the first optical component 200
than the circular opening hole 250 of the first optical component
200. The appearance of the imaging lens module includes, in order
from the object side to the image side, the first optical component
200 and the image surface 700, wherein an inside of the first
optical component 200 includes, in order from the object side to
the image side, the other four lens elements (101-104), the spacer
400, the light blocking plate 500, the lens element 110, and the
retainer 600. Therefore, it is favorable for maintaining the
structural strength and the image quality of the imaging lens
module.
