Abstract

An optical lens includes a lens barrel, a first lens, and an aperture. The lens barrel includes a first end and a second end. A receiving space is provided between the first end and the second end. The first end is provided with a light inlet opening communicating with the receiving space. The second end is provided with a light outlet opening communicating with the receiving space. A first light enters through the light inlet opening. A second light exits through the light outlet opening. The first lens is located in the receiving space and configured to receive and transmit at least a portion of the first light. The aperture is located in the receiving space and fixedly arranged on a side of the first lens facing away from the second end. The aperture is used to adjust an amount of the first light incident into the lens barrel.

First claim

What is claimed is:

1 . An optical lens comprising:
a lens barrel comprising a first end and a second end, a receiving space being provided between the first end and the second end, wherein the first end comprises a light inlet opening communicating with the receiving space, the second end comprises a light outlet opening communicating with the receiving space, a first light entering through the light inlet opening, and a second light exiting through the light outlet opening; a first lens in the receiving space and configured to receive and transmit at least a portion of the first light; and an aperture in the receiving space and fixedly arranged on a side of the first lens facing away from the second end, the aperture being configured to adjust an amount of the first light incident into the lens barrel.

2 . The optical lens of claim 1 further comprising:
adhesive fixes the aperture on a surface of the first lens facing away from the second end.

3 . The optical lens of claim 2 , further comprising:
a groove defined on the surface of the first lens, wherein the adhesive fills the groove.

4 . The optical lens of claim 3 , wherein:
the groove is an annular groove.

5 . The optical lens of claim 3 further comprising:
a bonding area defined on the first lens, wherein the bonding area is directly bonded to the aperture, the bonding area has a flat surface; and the groove is in the bonding area.

6 . The optical lens of claim 1 , wherein:
the first lens comprises a light transmission area and a flange area; the flange area is arranged around the light transmission area; the light transmission area is configured for transmitting the first light; the flange area is fixed on the lens barrel; and the aperture is fixedly arranged in the flange area of the first lens.

7 . The optical lens of claim 1 , wherein:
the first end of the lens barrel comprises a carrying portion; the carrying portion extends from the first end of the lens barrel to the light inlet opening; the carrying portion is located on a side of the aperture facing away from the first lens and configured for supporting the aperture.

8 . The optical lens of claim 1 , wherein:
the aperture is annular; the light inlet opening is an annular opening; and an inner diameter of the aperture is less than or equal to a diameter of the light inlet opening.

9 . The optical lens of claim 8 , wherein:
an imaginary line between a center of the aperture and a center of the first lens is perpendicular to an imaginary plane in which the aperture is located.

10 . The optical lens of claim 1 , further comprising a second lens and a third lens, wherein
the second lens and the third lens are located in the receiving space; and the first lens, the second lens, and the third lens are sequentially arranged in the receiving space along a direction from the first end to the second end.

11 . An electronic device comprising:
a display panel; and an optical lens coupled to the display panel, the optical lens comprising:
a lens barrel provided with a first end and a second end, a receiving space provided between the first end and the second end, the first end provided with a light inlet opening communicating with the receiving space, the second end provided with a light outlet opening communicating with the receiving space, a first light entering through the light inlet opening, and a second light exiting through the light outlet opening;
a first lens located in the receiving space and configured to receive and transmit at least a portion of the first light; and
an aperture located in the receiving space and fixedly arranged on a side of the first lens facing away from the second end, the aperture used to adjust an amount of the first light incident into the lens barrel; wherein:
the display panel displays images according to the second light.

12 . The electronic device of claim 11 , wherein:
an adhesive fixes the aperture on a surface of the first lens facing away from the second end.

13 . The electronic device of claim 12 , wherein:
the surface of the first lens is provided with a groove; and the adhesive is filled in the groove.

14 . The electronic device of claim 13 , wherein:
the groove is an annular groove.

15 . The electronic device of claim 13 , wherein:
the first lens comprises a bonding area directly bonded to the aperture; the bonding area has a flat surface; and the groove is located at the bonding area.

16 . The electronic device of claim 11 , wherein:
the first lens comprises a light transmission area and a flange area; the flange area is arranged around the light transmission area; the light transmission area is used for transmitting the first light; the flange area is fixed on the lens barrel; and the aperture is fixedly arranged in the flange area of the first lens.

17 . The electronic device of claim 11 , wherein:
the first end of the lens barrel comprises a carrying portion; the carrying portion extends from the first end of the lens barrel to the light inlet opening; the carrying portion is located on a side of the aperture facing away from the first lens and used for supporting the aperture.

18 . The electronic device of claim 11 , wherein:
the aperture is annular; the light inlet opening is an annular opening; and an inner diameter of the aperture is less than or equal to a diameter of the light inlet opening.

19 . The electronic device of claim 18 , wherein:
a line between a center of the aperture and a center of the first lens is perpendicular to a plane in which the aperture is located.

20 . The electronic device of claim 11 , further comprising a second lens and a third lens;
the second lens and the third lens are located in the receiving space; and the first lens, the second lens, and the third lens are sequentially arranged in the receiving space along a direction from the first end to the second end.
