[0123] One aspect of the present disclosure provides a light turning module, comprising a light turning element and an opaque body, wherein the opaque body is disposed corresponding to the light turning element. The light turning element is used to turn an incident optical axis to an exit optical axis, and comprises an entrance surface and an exit surface. The incident optical axis passes through and enters the entrance surface. The exit optical axis passes through and exits the exit surface. The opaque body comprises a non-enclosed ring structure and a plurality of light shielding structures. The exit optical axis passes through an open gap of the non-enclosed ring structure. The light shielding structures extend from the non-enclosed ring structure to the exit optical axis along a direction perpendicular to the exit optical axis, wherein the light shielding structures are disposed adjacent to the exit surface of the light turning element. The light shielding structures occupy an angle θe with the exit optical axis as the center, and the number of the light shielding structures is Ne, which satisfies the following conditions: 10 degrees < θe < 350 degrees; and 15 < Ne < 460. By disposing the light shielding structures in the direction to the exit optical axis, non-imaging light outside the imaging angle of view can be shielded to maintain image clarity.
[0124] Specifically, the light turning element can be a prism, a mirror, etc. The light shielding structures can be wedge-shaped, straight strip-shaped, petal-shaped, semi-cylindrical, or wavy, etc. In addition, if the direction parallel to the exit optical axis is the Z axis, then the direction perpendicular to the exit optical axis is any direction on an XY plane defined by the X and Y axes.
[0125] Further, the non-enclosed ring structure can be an appearance feature of the opaque body, such as a C-shaped, U-shaped, or I-shaped, etc., but the present disclosure is not limited thereto. The light shielding structures can be arranged on the non-enclosed ring structure along a circumferential direction around the exit optical axis.
[0126] Each light shielding structure can extend to and taper to meet the exit optical axis. In this way, the light shielding performance of the light shielding structures can be improved.
[0127] The opaque body and the light shielding structures can be integrally formed. In this way, the assembly process between the opaque body and the light shielding structures is eliminated, and the manufacturing is faster.
[0128] The angle of the light blocking structure is θe, and the number of the light blocking structures is Ne, which satisfy the following conditions: 10 degrees < θe < 150 degrees; and 15 < Ne < 250. In this way, the reflection path of the non-imaging light can be destroyed on the surface of the specific position of the opaque body, so that the non-imaging light cannot enter the imaging lens, thereby improving the imaging quality. Specifically, the light blocking structure can be arranged in a linear arrangement in a non-closed ring structure.
[0129] The angle of the light blocking structure is θe, and the number of the light blocking structures is Ne, which satisfy the following conditions: 110 degrees < θe < 350 degrees; and 50 < Ne < 300. In this way, the light blocking requirement of various optical designs can be met to improve the optical design margin. Specifically, the light blocking structure can be arranged in a U-shaped arrangement in a non-closed ring structure.
[0130] Each light blocking structure is a wedge-shaped protrusion, and the wedge-shaped protrusion has an included angle θe', which satisfies the following conditions: 0 degrees < θe' < 90 degrees. In this way, the design of the wedge-shaped protrusion helps to destroy the reflection path of the non-imaging light, thereby improving the light blocking effect. Specifically, the opaque body can be a holder or a carrier made of plastic injection molding, which uses a mold to transfer the appearance of the wedge-shaped or semi-cylindrical shape of each light blocking structure; the opaque body can also be a light blocking sheet made by stamping processing, which uses a mold to cut out the appearance of the wedge-shaped or petal-shaped of each light blocking structure, but the present disclosure is not limited thereto.
[0131] Each light blocking structure forms a convex arc, and the convex arc has a radius of curvature Re, which satisfies the following conditions: 0 mm < Re < 0.3 mm. In this way, it helps to destroy the reflection path of the non-imaging light, thereby improving the light blocking effect.
[0132] Each light blocking structure forms a concave arc, and the concave arc has a radius of curvature Re', which satisfies the following conditions: 0 mm < Re' < 0.3 mm. In this way, it helps to destroy the reflection path of the non-imaging light, thereby improving the light blocking effect.
[0133] The non-closed ring structure can further include at least one auxiliary arc, at least a portion of the light blocking structure is arranged on the auxiliary arc, and the auxiliary arc has a radius of curvature r, which satisfies the following conditions: 0.5 mm < r < 50 mm. In this way, the ghosting (flare) at a specific angle can be eliminated, so that the imaging image is clear. In detail, the light blocking structure (including wedge-shaped protrusion, convex arc, concave arc, or continuous arrangement of convex arc and concave arc) can be further arranged on the auxiliary arc.
[0134] A height of each light shielding structure extending along a direction perpendicular to the outgoing light axis is He, which satisfies the following condition: 0.01 mm < He < 1.2 mm. In this way, the height extending range with better light shielding effect is increased.
[0135] A length of each light shielding structure extending along a direction parallel to the outgoing light axis is Le, which satisfies the following condition: 0.01 mm < Le < 2.8 mm. In this way, the length extending range with better light shielding effect is increased.
[0136] In addition, the light turning element can be made of plastic, and the light blocking body can be made of black plastic, but the disclosure is not limited thereto.
[0137] One aspect of the disclosure provides a light turning module, comprising a light turning element and a light blocking body, wherein the light blocking body is arranged correspondingly with the light turning element. The light turning element is used to turn an incident light axis to an outgoing light axis, and comprises an incident surface and an outgoing surface. The incident light axis passes through and enters the incident surface. The outgoing light axis passes through and exits the outgoing surface. The light blocking body comprises a non-closed ring structure and a plurality of light shielding structures. The incident light axis passes through an open gap of the non-closed ring structure. The light shielding structures extend from the non-closed ring structure towards the incident light axis along a direction perpendicular to the incident light axis, wherein the light shielding structures are arranged adjacent to the incident surface of the light turning element. The angle occupied by the light shielding structures with the incident light axis as the center is θi, and the number of the light shielding structures is Ni, which satisfies the following conditions: 10 degrees < θi < 350 degrees; and 15 < Ni < 460. By arranging the light shielding structures towards the incident light axis, non-imaging light outside the imaging viewing angle can be shielded to maintain image clarity.
[0138] Each light shielding structure can extend towards the incident light axis and taper to meet. In this way, the light shielding performance of the light shielding structure can be increased.
[0139] The light blocking body and the light shielding structure can be integrally formed. In this way, the assembly process between the light blocking body and the light shielding structure can be eliminated, and the manufacturing is faster.
[0140] The angle occupied by the light shielding structures with the incident light axis as the center is θi, and the number of the light shielding structures is Ni, which satisfies the following conditions: 10 degrees < θi < 150 degrees; and 15 < Ni < 250. In this way, the reflection path of the non-imaging light on the surface of the light blocking body at a specific position can be destroyed, so that the non-imaging light cannot enter the imaging lens, thereby improving the imaging quality. Specifically, the light shielding structures can be arranged in a linear arrangement on the non-closed ring structure.
[0141] The angle of the light shielding structure is θi, and the number of the light shielding structures is Ni, which satisfy the following conditions: 110 degrees < θi < 350 degrees; and 50 < Ni < 300. In this way, the light shielding requirement of various optical designs can be met to improve the optical design margin. Specifically, the light shielding structures can be arranged in a U-shaped arrangement in the non-closed loop structure.
[0142] Each light shielding structure can be a wedge-shaped protrusion with an included angle θi', which satisfies the following conditions: 0 degrees < θi' < 90 degrees. In this way, the design of the wedge-shaped protrusion helps to break the reflection path of the non-imaging light, improving the light shielding effect.
[0143] Each light shielding structure forms a convex arc with a radius of curvature Ri, which satisfies the following conditions: 0 mm < Ri < 0.3 mm. In this way, it helps to break the reflection path of the non-imaging light, improving the light shielding effect.
[0144] Each light shielding structure forms a concave arc with a radius of curvature Ri', which satisfies the following conditions: 0 mm < Ri' < 0.3 mm. In this way, it helps to break the reflection path of the non-imaging light, improving the light shielding effect.
[0145] The non-closed loop structure can further include at least one auxiliary arc, at least a portion of the light shielding structures being arranged on the auxiliary arc, the auxiliary arc having a radius of curvature r, which satisfies the following conditions: 0.5 mm < r < 50 mm. In this way, ghosting (flare) at a specific angle can be eliminated to make the imaging image clear. In detail, the light shielding structures (including wedge-shaped protrusions, convex arcs, concave arcs, or continuous arrangement of convex arcs and concave arcs) can be further arranged on the auxiliary arc.
[0146] The height of each light shielding structure extending in the direction perpendicular to the incident light axis is Hi, which satisfies the following conditions: 0.01 mm < Hi < 1.2 mm. In this way, the height extension range has a better light shielding effect.
[0147] The length of each light shielding structure extending in the direction parallel to the incident light axis is Li, which satisfies the following conditions: 0.01 mm < Li < 2.8 mm. In this way, the length extension range has a better light shielding effect.
[0148] In addition, the light turning element can be a plastic material, and the opaque body can be a black plastic material, but the present disclosure is not limited thereto.
[0149] It must be pointed out that the opaque body of the light turning module of any aspect of the present disclosure is not limited to being adjacent to only one of the light entering surface and the light exiting surface of the light turning element and the light shielding structure, but can also be adjacent to both the light entering surface and the light exiting surface of the light turning element and the light shielding structure.

[0151] This disclosure provides an electronic device comprising a camera module as described above and an electronic photosensitive element, wherein the electronic photosensitive element is disposed on an imaging surface of the camera module.
