Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In the prior art, the light transmission component mainly comprises a lens. In the process of photographing or shooting, stray light enters the light-transmitting component and is reflected for multiple times in the light-transmitting component, and the defects of halation, shadow or flare radiated outwards and the like appear at the imaging edge. And the defect is more serious with the enhancement of ambient light, and the defect can seriously affect the imaging quality under the outdoor strong light environment.

In order to solve the above technical problem, referring to fig. 1 to 4, the present application provides a light transmission assembly 10, wherein the light transmission assembly 10 includes at least one lens 100. The light-transmitting component 10 is a combination of components that allow light to pass through in the camera device, and the light-transmitting component 10 mainly includes a lens 100. The lens 100 is made of an optically transparent material such as glass or resin, and has one or more curved surfaces, which can change the propagation direction of light, control the light distribution to converge the light, and finally form an image. The lens 100 can be divided into a convex lens and a concave lens according to the shape and function thereof, and the material, type, size, etc. of the lens 100 are not limited in this application.

In the light-transmitting assembly 10, the lens 100 is disposed in the lens barrel 300 of the camera module 20 to cooperate with other components of the camera module 20, such as a photosensitive element, to realize an imaging function. The installation position and installation manner of the lens 100 in the lens barrel 300 are not limited, and can be flexibly adjusted according to different imaging requirements. Each lens 100 includes an imaging portion 110 and a non-imaging portion 120 disposed about the imaging portion 110. The imaging part 110 is a portion of the lens 100 directly irradiated and transmitted by the light entering the camera module 20, and the lens 100 distributes the light through the imaging part 110. The shape, size, and position of the imaging portion 110 on the lens 100 are not particularly limited, and may be determined according to the shape, size, and mounting position of the lens 100. The non-imaging portion 120 is disposed for facilitating the connection and fixation of the lens 100, and the light entering the camera module 20 does not directly irradiate and pass through the non-imaging portion 120, but some light irradiates the non-imaging portion 120 under the reflection action of other components in the camera module 20, so that the non-imaging portion 120 is disposed around the imaging portion 110, and the light irradiating the imaging portion 110 is not blocked while the imaging portion 110 is connected and fixed. The non-imaging section 120 may be connected and fixed to the lens barrel 300, or may be connected and fixed to other components of the camera module 20, such as a spacer ring, a spacer, and the like, and the connection and fixation manner is not limited, and may be an abutment, an adhesive, a snap, or the like. To facilitate processing of the lens 100, the imaging portion 110 and the non-imaging portion 120 of the lens 100 may be integrally provided. The specific boundary between the imaging section 110 and the non-imaging section 120 may not be divided, and may be distinguished only by a difference in shape.

Wherein a surface of at least one of the non-image forming portions 120 is provided with a photochromic film 200 to dissipate light intensity of reflected light reflected by the non-image forming portion 120. The photochromic film 200 is a thin film that can be attached to the non-image forming portion 120 and has photochromic properties. The photochromic property is a form of radiation color change, which means that a component M in the photochromic film 200 can chemically react to generate another component N when irradiated by light, and the component N has a different color (i.e., a different degree of absorption of light) from the component M. The component N can be recovered to the component M under the irradiation of another light beam or by heating. I.e., the reversibility of the photochromic property, is an important feature of the photochromic film 200. The irreversible reaction under the action of light can also result in a change in colour, but this is only of a general photochemical character and not of photochromic nature. Tungsten oxide is a good photochromic material, and the photochromic film 200 of the present embodiment may be the one containing tungsten oxide.

By providing the photochromic film 200 in the non-imaging portion 120, the light reflected to the non-imaging portion 120 changes the color of the photochromic film 200, changes the color from the initial colorless transparency to gray, black and the like, plays a role in dissipating and shielding the light reflected to the non-imaging portion 120, and dissipates the light intensity of the reflected light, thereby avoiding the defects of halation, shadow or flare of outward radiation and the like occurring at the imaging edge due to multiple reflections of stray light in the light transmitting component 10. And compared with the atomization treatment of the lens 100, the photochromic film 200 is simple and convenient to arrange, and the forming precision of the lens 100 can be improved.

Referring to fig. 1, in the light transmission assembly 10 according to the first embodiment of the present application, the non-imaging portion 120 includes a first surface 121, and the first surface 121 is located on the object side of the lens 100. The non-imaging portion 120 is a space structure formed by a combination of different surfaces on the lens 100, and includes a first surface 121 located on the object side of the lens 100. As is well known to those skilled in the art, the lens 100 includes two opposite sides, wherein a side of the lens 100 close to the object is an object side, a surface of the lens 100 on the object side is an object side, and a side of the lens 100 away from the object is an image side, and a surface of the lens 100 on the image side is an image side. The first surface 121 may be a continuous plane or a continuous curved surface, and the first surface 121 may also be a surface formed by a plurality of discontinuous planes or curved surfaces. In this embodiment, as shown in fig. 1, the lead line with an arrow indicates a direction of an optical axis of the lens 100, side a is an image side of the lens 100, a surface of the lens 100 on side a is an image side, side B is an object side of the lens 100, and a surface of the lens 100 on side B is an object side. The photochromic film 200 is disposed on the first surface 121, and functions to dissipate and block the light reflected to the non-image-forming portion 120 on the object side of the lens 100, thereby dissipating the intensity of the reflected light. Since the object side is the direction from which the light in the light-transmitting component 10 originates, the intensity of the light at the object side is also the strongest, and the photochromic film 200 is disposed on the object side, so that the intensity of the light reflected in the light-transmitting component 10 can be dissipated to the greatest extent, and defects such as halo, shadow or flare radiated outwards due to multiple reflections of stray light in the light-transmitting component 10 can be avoided to the greatest extent.

Referring to fig. 2, in the light transmission assembly 10 according to the second embodiment of the present application, the non-imaging portion 120 includes a second surface 122, and the second surface 122 is located on the image side surface of the lens 100. The side of the lens 100 facing away from the object is the image side, and the surface of the lens 100 on the image side is the image side. The second surface 122 may be a continuous plane or a continuous curved surface, and the second surface 122 may also be a surface formed by a plurality of discontinuous planes or curved surfaces. In this embodiment, as shown in fig. 2, the lead line with an arrow indicates the direction of the optical axis of the lens 100, side a is the image side of the lens 100, the surface of the lens 100 on side a is the image side, side B is the object side of the lens 100, and the surface of the lens 100 on side B is the object side. The photochromic film 200 is disposed on the second surface 122 and is capable of dissipating and blocking light reflected to the non-imaging portion 120 on the image side of the lens 100, thereby dissipating the intensity of the reflected light. Since the image side is the side of the light-transmitting assembly 10 close to the imaging area, the reflected light on the image side has the greatest influence on the final imaging, the reflected light on the image side may directly enter the imaging area after being reflected to affect the imaging quality, and the photochromic film 200 is disposed on the image side, so that the light intensity of the reflected light on the image side can be dissipated before the final imaging, and the imaging defect is avoided.

Referring to fig. 3, in the light transmission assembly 10 according to the third embodiment of the present application, the non-imaging portion 120 includes a peripheral side surface 123 for abutting against the lens barrel 300. As mentioned above, the peripheral side surface 123 is the surface of the lens 100 that connects the object side surface and the image side surface. The peripheral side surface 123 may be a continuous plane or a continuous curved surface, and the peripheral side surface 123 may also be a surface formed by a plurality of discontinuous planes or curved surfaces. In this embodiment, as shown in fig. 3, the lead line with an arrow indicates the direction of the optical axis of the lens 100, side a indicates the image side of the lens 100, the surface of the lens 100 on side a indicates the image side, side B indicates the object side of the lens 100, the surface of the lens 100 on side B indicates the object side, and the peripheral side 123 indicates the surface connecting the object side and the image side. The photochromic film 200 is disposed on the peripheral surface 123, and can dissipate and block the light reflected between the lens 100 and other components, and dissipate the light intensity of the reflected light. Since the peripheral side surface 123 is a position where the lens 100 is fixed to other parts, where the structure is complicated, and other portions of light are most likely to be collected and reflected many times, the photochromic film 200 provided on the peripheral side surface 123 can dissipate the intensity of light of reflected light collected in a portion, thereby avoiding image defects.

It should be noted that the photochromic film 200 may be separately disposed on either one or both of the first surface 121 or the second surface 122 or the peripheral side surface 123, or may be disposed on both of the first surface 121 and the second surface 122 and the peripheral side surface 123, in order to have an optimal dissipation and shielding effect on the reflected light, and to avoid the defects of halo, shadow or flare of the outward radiation occurring at the imaging edge due to multiple reflections of stray light in the light transmitting assembly 10 to the maximum extent, in the light transmitting assembly 10 of the fourth embodiment of the present application, the photochromic film 200 completely covers the surface of the non-imaging portion 120, that is, the photochromic film 200 is disposed on both of the first surface 121, the second surface 122 and the peripheral side surface 123. As shown in fig. 4, the lead with an arrow is the direction of the optical axis of the lens 100, side a is the image side of the lens 100, the surface of the lens 100 on side a is the image side, side B is the object side of the lens 100, the surface of the lens 100 on side B is the object side, the peripheral side 123 is the surface connecting the object side and the image side, and the object side, the image side and the peripheral side 123 of the non-imaging portion 120 are all covered with the photochromic film 200, so that the reflected light on the non-imaging area of the lens 100 can be fully dissipated and blocked, and the effect of avoiding the imaging defect is optimal.

When the photochromic film 200 is applied to the lenses 100 with different structures, kinds and functions, the thickness of the photochromic film 200 can be adjusted within a reasonable range to improve the general performance of the light-transmitting assembly 10. In one embodiment, the thickness of the photochromic film 200 is 5nm to 1000nm, for example, the thickness of the photochromic film 200 may be 5nm, 100nm, 500nm, or 1000 nm. When the thickness of the photochromic film 200 is small, the photochromic film has little influence on the structure of the lens 100, has high aesthetic degree, and does not influence the assembly of the lens 100; when the thickness of the photochromic film 200 is large, the dissipation degree of the reflected light is strong, the production and the processing are convenient, and the photochromic film 200 is easily attached to the lens 100. Meanwhile, the number of layers of the photochromic film 200 may also be flexibly adjusted according to actual use requirements, and in one embodiment, the number of layers of the photochromic film 200 is at least one. By appropriately increasing or decreasing the number of layers of the photochromic film 200, the imaging quality of the light-transmitting member 10 can be easily adjusted to the optimum.

Referring to fig. 5 to 7, the present application further provides a camera module 20, where the camera module 20 includes a lens barrel 300 and the light-transmitting component 10 as described above.

According to practical requirements, the light-transmitting component 10 can adopt the lens 100 of any one of the first, second, third and fourth embodiments of the present application, so as to achieve different imaging effects.

Referring to fig. 5, in a fifth embodiment of the present application, a lens 100 is included in the light-transmitting component 10. In some usage scenarios, different shooting requirements, such as wide angle, zooming, etc., may not be satisfied by one lens 100, and therefore, the number of lenses 100 of the light transmission assembly 10 may be multiple to achieve different shooting functions. Referring to fig. 6, in a sixth embodiment of the present application, the number of the lenses 100 of the light transmission assembly 10 is multiple, each lens 100 is stacked in the lens barrel 300, and each lens 100 includes an imaging portion 110 and a non-imaging portion 120 disposed around the imaging portion 110. The lenses 100 may be all the same type of lenses 100, or different lenses 100 may be used, and the lenses 100 are stacked in the barrel 300. The types and parameters of the lenses 100 may be the same or different, but each lens 100 includes an imaging portion 110 and a non-imaging portion 120 disposed around the imaging portion 110 to cooperate with each other to achieve an imaging function.

In order to dissipate the light intensity of the reflected light of the image capturing module 20 at the object side to the maximum extent when a plurality of lenses 100 are stacked in the lens barrel 300, in this embodiment, the lens barrel 300 includes a light inlet 310, the lens 100 of the light transmitting assembly 10 closest to the light inlet 310 is the light-entering lens 100, and the surface of the non-imaging portion 120 of the light-entering lens 100 is provided with the photochromic film 200. The light inlet 310 is an opening disposed on the object side of the lens barrel 300, and light passes through the object side of the image capturing module 20 from the light inlet 310 and irradiates the image side of the image capturing module 20. As shown in fig. 6, the lead line with an arrow indicates the direction of the optical axis of the image capturing module 20, the side a is the image side of the image capturing module 20, the side B is the object side of the image capturing module 20, and the opening of the lens barrel 300 close to the side B is the light inlet 310. Therefore, among the plurality of lenses 100 in the lens barrel 300, the lens 100 closest to the light inlet 310 may be referred to as the light inlet lens 100, since the object side is the direction from which the light in the camera module 20 originates, and therefore, the light intensity at the light inlet 310 is also the strongest, and the photochromic film 200 is disposed on the surface of the non-imaging portion 120 of the light inlet lens 100, so as to dissipate the light intensity of the reflected light in the camera module 20 to the maximum, and to avoid the defects such as halo, shadow, or flare radiated outward at the imaging edge due to multiple reflections of the stray light in the camera module 20 to the maximum.
