The light filling lamp module can be classified according to the lighting mode: base lighting and accent lighting. Basic lighting, namely ambient lighting, refers to overall basic lighting in a whole scene, and the main problem of the basic lighting for supplementary lighting is low optical efficiency. The key illumination is targeted illumination on a specific part of a scene, a lens generally has a specific shooting area, and under the guidance of the concepts of high efficiency, energy conservation, low light pollution and environmental protection, the application of the key illumination light supplement lamp module with higher optical efficiency on electronic equipment is a necessary trend. Some lenses have barrel or pincushion distortion at the edge of the field of view, i.e. the range of the lens field is generally barrel or pincushion shaped. Most of the existing fill-in light modules are circular lighting areas, and a few of the existing fill-in light modules are oval or rectangular lighting areas.

Wherein the negative correlation is a change in the opposite direction. For example, the first dimension is inversely related to the second dimension, i.e., as the first direction changes, the larger the second dimension, the smaller the first dimension. The third dimension is inversely related to the second dimension, i.e. the larger the second dimension, the smaller the third dimension as the first direction changes.

The optical axis of the light supplement lens is the central line of the light supplement lens, and the direction of light entering the light supplement lens along the optical axis of the light supplement lens is unchanged when the light is emitted.

Generally, the field of view of any lens module is close to the optical axis of the lens module and has almost no abnormal distortion, that is, paraxial rays of the lens module can be imaged almost without distortion, so that the area of the field of view close to the optical axis of the lens module is suitable for circular or rectangular supplementary lighting; the farther the field range of the lens module is from the optical axis of the lens module, the larger the positional distortion, i.e., the farther the lens module is from the optical axis of the lens module, the larger the imaging distortion (barrel distortion or pincushion distortion) is, and therefore, the pillow-filled light or barrel-filled light is more suitable for the area farther from the optical axis of the lens module. The optical axis of the lens module is the center line of the lens module, and the direction of light rays entering the lens module along the optical axis of the lens module is unchanged when the light rays are emitted.

Referring to fig. 3, fig. 3 is a schematic cross-sectional view of the lens module 100 in fig. 2 along the optical axis a of the lens module 100. The optical axis a of the lens module 100 is a central line of the lens module 100, and the direction of the light beam entering the lens module 100 along the optical axis a is not changed when the light beam exits. The lens module 100 includes a lens 10 and a light-sensing device 20. The lens 10 includes a plurality of coaxially arranged lenses 11. The optical axis of each lens 11 is collinear with the optical axis a of the lens module 100, wherein the optical axis of the lens 11 is a central line of the lens 11, a direction of a light ray entering the lens 11 along the optical axis of the lens 11 is unchanged when the light ray exits, and the optical axis of the lens 11 is collinear with the optical axis a of the lens module 100. The light sensing element 20 is located on the image side of the lens 10. The image side of the lens 10 refers to a side of the lens 10 close to an image of a subject to be imaged. When the lens module 100 is in operation, light reflected by the surface of a scene to be imaged is refracted by the plurality of lenses 11 in the lens 10 and then imaged on the photosensitive element 20. The photosensitive element 20 is a semiconductor chip, and includes a photodiode having a surface with hundreds of thousands to millions of photodiodes, and generates electric charges when irradiated with light, thereby converting an optical signal into an electrical signal.

In the present embodiment, the photosensitive element 20 has a rectangular shape, and the center thereof is located on the optical axis of the lens 10. The optical axis of the lens 10 is the optical axis of the plurality of lenses 11 in the lens 10, and the optical axis of the lens 10 is collinear with the optical axis a of the lens module 100.

The diaphragm 12 may be an aperture diaphragm 12, and the aperture diaphragm 12 is used to limit the amount of incident light to change the brightness of the image.

In some embodiments, the lens 10 further includes an electromagnetic/electromechanical filter switcher (ICR). The ICR is located between the photosensitive element 20 and the lens 11 of the lens 10. Under the condition of sufficient illumination (such as daytime), the ICR automatically adds an infrared filter between the photosensitive element 20 and the lens 11 of the lens 10. The light refracted by each lens 11 of the lens 10 is irradiated onto the infrared filter 30, and is transmitted to the photosensitive element 20 through the infrared filter 30. The infrared filter 30 can filter out unnecessary light projected onto the photosensitive element 20, and prevent the photosensitive element 20 from generating false color or moire, so as to improve the effective resolution and color reproducibility thereof, so that the lens 10 can monitor in a color mode. Under the condition of low illumination (such as at night or under the condition of extremely dark light), the ICR can automatically remove the infrared filter, so that the lens 10 is automatically converted into a black-and-white mode for monitoring, and the lens 10 can work under any illumination scene.

The circuit board 60 may be a Flexible Printed Circuit (FPC) or a Printed Circuit Board (PCB), wherein the FPC may be a single-sided flexible board, a double-sided flexible board, a multi-layer flexible board, a rigid flexible board, a hybrid-structured flexible circuit board, or the like. Other elements included in the lens module 100 are not described in detail herein. In some embodiments, the ICR may be secured to the wall of a stationary canister 51 of the stationary base 50. It will be appreciated that in some embodiments, the ICR may also be supported and secured to the circuit board 60 by a bracket.

The photosensitive element 20 is fixed to the circuit board 60 by bonding or mounting. The light receiving element 20 is located on the image side of the lens 10 and is disposed opposite to the lens 10; the light sensing element 20 is located on the focal plane of the lens 10, and the optical image generated by the lens 10 can be projected to the light sensing element 20. In some embodiments, the light sensing element 20 is connected to other components of the electronic device 1000 through the circuit board 60, so as to implement communication connection between the light sensing element 20 and other components of the electronic device 1000. For example, the electronic device 1000 further includes components such as a processor, a memory, and the like. Components such as a processor and a memory can also be integrated on the circuit board 60 by bonding or by a patch, so that the communication connection between the photosensitive element 20, the processor, the memory, and the like is realized through the circuit board 60. After the optical image generated by the lens 10 is projected to the photosensitive element 20, the photosensitive element 20 can convert the optical image into an electrical signal and transmit the electrical signal to the processor. The processor is used for processing the electric signals of the image to obtain a better shot picture or image. In some embodiments, the processor stores the processed captured image or video in the memory.

In some embodiments, the lens 10 can be telescopically received in the fixed cylinder 51 of the fixed base 50, so as to change the distance between the lens 10 and the photosensitive element 20. For example, in some embodiments, the distance between the plurality of lenses 11 in the lens 10 is adjustable, and as the distance between the plurality of lenses 11 in the lens 10 changes, the focal length of the lens 10 changes, and accordingly the lens 10 is moved relative to the fixed base 50, so as to change the distance between the photosensitive element 20 and the lens 10, and ensure that the photosensitive element 20 is always located on the focal plane of the lens 10, and ensure that the lens module 100 can always obtain better images in a state where the focal length of the lens 10 changes arbitrarily. Alternatively, when the camera module 100 does not need to work, the lens 10 may be retracted relative to the fixed base 50, so that one end of the lens 10 is close to the photosensitive element 20; when the camera module 100 is in operation, the lens 10 is extended relative to the fixed base 50, such that one end of the lens 10 is away from the photosensitive element 20 until the photosensitive element 20 is located on the focal plane of the lens 10. That is, by extending and retracting the lens 10 with respect to the fixed base 50 in different usage scenarios, the size of the lens module 100 can be reduced as much as possible while ensuring the photographing effect, so that the lens module 100 can be more suitably used in the electronic device 1000 having a smaller size and a thinner profile.

Referring to fig. 2 and 4 again, fig. 4 is a schematic cross-sectional view of the fill light module 200 shown in fig. 2 along the direction of the optical axis b. The optical axis b of the light supplement lamp module 200 is the central line of the light supplement lamp module 200, and the direction of light entering the light supplement lamp module 200 along the optical axis b is unchanged when the light exits. The light supplement lamp module 200 includes a lamp panel 210, a light source 220 and a light supplement lens 230. The optical axis of the light supplement lens 230 is a central line of the light supplement lens 230, and the direction of light entering the light supplement lens 230 along the optical axis of the light supplement lens 230 is unchanged when the light exits, and the optical axis of the light supplement lens 230 is collinear with the optical axis b of the light supplement module 200. The light source 220 is a component for emitting light, and may be composed of one light emitting device or an array composed of a plurality of light emitting devices. In this embodiment, the light source 220 is a single LED lamp. In some embodiments, the light source 220 may also be an LED lamp array composed of a plurality of LED lamps. It is understood that the type of the light source 220 in the present application can be adaptively changed according to the need. For example, in some embodiments, the light source 220 may be a laser, a xenon lamp, an incandescent lamp, a fluorescent lamp, a high-pressure mercury lamp, or other types of light sources.

The light source 220 and the fill-in lens 230 are fixed on the lamp panel 210. The light compensating lens 230 is fixed to the lamp panel 210 and covers the light source 220. The light emitted from the light source 220 is refracted or reflected by the light supplementing lens 230 and then emitted, and the light emitting angle of the light is adjusted by the light supplementing lens 230, so that a light supplementing range with a required shape and size is obtained.

The lamp panel 210 is a circuit board, and the light source 220 is fixed on the lamp panel 210 and electrically connected to the traces in the lamp panel 210. In some embodiments, the electronic device 1000 further comprises a driving control circuit for controlling the light source 220 to be turned on or off, or controlling the brightness of the light source 220, and the like. The circuit in lamp plate 210 is connected with drive control circuit, realizes the electricity between light source 220 and the drive control circuit through lamp plate 210 to realize drive control circuit to the control of light source 220.

Referring to fig. 5 and 6 together, fig. 5 is a schematic structural diagram of the fill-in lens 230 shown in fig. 2, and fig. 6 is a side view of the fill-in lens 230 shown in fig. 5. In this embodiment, the light compensating lens 230 is an integrated lens structure. The fill lens 230 includes a first surface 231 and a second surface 232 disposed opposite to each other, and a peripheral surface 233 connected between the first surface 231 and the second surface 232. The area of the first surface 231 of the fill lens 230 is smaller than that of the second surface 232. The light source 220 is disposed on a side of the fill lens 230 close to the first surface 231. In the present embodiment, the first surface 231 is provided with a receiving cavity 234 recessed toward the second surface 232, and the receiving cavity 234 is used for receiving the light source 220. The housing cavity 234 includes a bottom wall 2341 and a peripheral wall 2342, the bottom wall 2341 faces the first surface 231, and the peripheral wall 2342 connects the bottom wall 2341 and the first surface 231. Light emitted from the light source 220 enters the fill lens 230 through the bottom wall 2341 and the peripheral wall 2342 of the accommodating cavity 234. The peripheral surface 233 is a reflection surface for reflecting a part of the light emitted from the light source 220. Specifically, in some embodiments of the present disclosure, the refractive index of the material forming the light filling lens 230 is greater than the refractive index of air, so that the light emitted from the light source 220 is totally reflected when the light irradiates the peripheral surface 233, and the peripheral surface 233 serves as a reflecting surface. In some embodiments, the circumferential surface 233 may be coated with a surface treatment such as a reflective film so that the circumferential surface 233 can serve as a reflective surface. The second surface 232 is a light emitting surface. Part of the light emitted by the light source 220 is reflected by the peripheral surface 233 and then exits from the second surface 232, and the rest of the light is refracted by the light supplement lens 230 and then exits from the second surface 232. In some embodiments, the light source 220 may also be directly disposed on a side of the first surface 231 away from the second surface 232, where the first surface 231 is a light incident surface, and light emitted from the light source 220 enters the light via the first surface 231 and exits from the second surface 232 after being reflected and refracted by the light filling lens 230. In the present embodiment, the first surface 231 and the second surface 232 are both planes perpendicular to the optical axis of the fill lens 230. The bottom wall 2341 of the accommodating cavity 234 is a plane perpendicular to the optical axis of the fill-in lens 230, or a rotationally symmetric curved surface with the optical axis of the fill-in lens 230 as the central axis.

In some embodiments of the present application, the receiving cavity 234 is truncated cone-shaped or elliptical. The opening area of the accommodating cavity 234 is larger than the area of the orthographic projection of the bottom wall 2341 of the accommodating cavity 234 on the first surface 231, so that the accommodating cavity 234 has a draft angle, and demolding and other operations are facilitated when the light supplement lens 230 is manufactured through a mold. When the accommodating cavity 234 is in a circular truncated cone shape, the section of the accommodating cavity 234 at any position perpendicular to the optical axis b is circular; when the housing cavity 234 is formed in an elliptical truncated shape, the cross section of the housing cavity 234 at any position perpendicular to the optical axis b is elliptical. When the accommodating cavity 234 is in a circular truncated cone shape or an elliptical truncated cone shape, it can be ensured that the light path of the light emitted into the light filling lens 230 through the bottom wall surface 2341 of the accommodating cavity 234 and the light path of the light reflected by the circumferential surface 233 of the light filling lens 230 can be decoupled from each other. That is, by separately changing the curved surface shape of the peripheral surface 233 (i.e., changing the shape of the cross section of the fill-in lens 230 perpendicular to the optical axis b), the light entering through the sidewall 2342 of the receiving cavity and reflected by the peripheral surface 233 is emitted, and then the desired fill-in range size and shape can be formed. Alternatively, the size and shape of the light supplement range required for forming the part of the light incident through the bottom wall 2341 can be achieved by independently changing the curved surface shape of the bottom wall 2341 of the accommodating cavity 234. In other words, the size and shape of the target fill-in light range are controlled by the bottom wall 2341 and the size and shape of the target fill-in light range are controlled by the peripheral surface 233, so that the light path of the light entering the fill-in light lens 230 through the bottom wall 2341 of the accommodating cavity 234 and the light path of the light reflected by the peripheral surface 233 of the fill-in light lens 230 are decoupled from each other, the degree of freedom of the size and shape of the target fill-in light range that can be realized by the fill-in light module 200 is higher, the design variables are reduced, the required fill-in light module 200 can be easily and accurately designed, the shape and size of the target fill-in light range can be obtained (i.e., the shape and size of the fill-in light range of the fill-in light module 200 are basically the same as the shape and size of the field range), uniform fill-in light can be obtained at each position of the field, accurate accent lighting is realized, waste of light is avoided, and the optical efficiency of the fill-in light module 200 is improved, and reduces veiling glare outside the field of view.

In the present embodiment, the housing cavity 234 has a truncated cone shape. It is understood that in some embodiments, the receiving cavity 234 may also have a cylindrical or elliptical cylindrical shape.

In this application, a dimension of a cross section of the light filling lens 230 perpendicular to the optical axis b in the first direction is a first dimension, and a dimension of the second surface 232 in the first direction is a third dimension. The cross section of the light supplement lens 230 perpendicular to the optical axis b refers to an area surrounded by the outline of the light supplement lens 230 on a plane perpendicular to the optical axis b after the light supplement lens 230 is cut off. The size of the field range of the lens 10 in the first direction is a second size. The first direction and the vertical viewing field direction of the lens 10 form a first included angle, and the first size and the third size are both inversely related to the second size. Wherein the negative correlation is a change in the opposite direction. For example, the first dimension is inversely related to the second dimension, i.e., as the first direction changes, the larger the second dimension, the smaller the first dimension. The third dimension is inversely related to the second dimension, i.e., the larger the second dimension, the smaller the third dimension as the first direction changes. In this application, according to the first size and the third size and the negative relevant corresponding relation of second size, thereby obtain corresponding light filling lens 230 according to the field of view scope of camera lens 10, make the light filling scope of light filling lamp module 200 the shape of the field of view scope rather than the camera lens 10 that corresponds the same basically, and the light filling scope of light filling lamp module 200 can cover the field of view scope of its camera lens 10 that corresponds completely, thereby guarantee that light filling lamp module 200 can carry out the light filling for each position in the field of view scope of camera lens 10, can avoid the waste of light energy of light filling lamp module 200 again simultaneously, and reduce the miscellaneous light outside the field of view scope of camera lens 10, reduce light pollution. It should be noted that, in the present application, the field range of the lens module 100 is a field range of the lens 10, in other words, the field range of the lens module 100 is a field range of the lens 10.

The light supplement range of the light supplement lamp module 200 can completely cover the field of view of the lens 10, that is, the light supplement range of the light supplement lamp module 200 can coincide with the field of view of the lens 10, or the light supplement range of the light supplement lamp module 200 can be slightly larger than the field of view of the lens 10. In other words, when the shooting plane of the lens 10 is coplanar with the illumination plane of the light supplement lamp module 200, the field range of the lens 10 on the shooting plane completely coincides with the spot area of the light supplement lamp module 200 on the illumination plane, or is located in the spot area of the light supplement lamp module 200 on the illumination plane. Referring to fig. 7, fig. 7 is a schematic position diagram illustrating a field range of the lens 10 and a fill-in range of the fill-in lamp module 200 of the electronic device 1000 according to the embodiment shown in fig. 2. The area enclosed by the solid lines is the light supplement range of the light supplement lamp module 200, and the area enclosed by the dotted lines is the field range of the lens 10. In the present embodiment, the field range of the lens 10 is pincushion-shaped. The light supplement range of the light supplement lamp module 200 is pillow-shaped and is the same as the field range formed by the lens 10, and is slightly larger than the field range of the lens 10, and the field range of the lens 10 is located in the light supplement range of the light supplement lamp module 200.

It is understood that in other embodiments of the present application, the field of view formed by the lens 10 may be barrel-shaped, pillow-shaped, or rectangular, square, and the like, and the fill-in lens 230 having a fill-in range substantially the same as the shape and size of the field of view formed by the lens 10 can also be obtained according to the correspondence relationship between the first size and the second size in negative correlation. For example, the field of view formed by the lens module 100 is barrel-shaped, and the light supplement range of the light supplement module 200 where the light supplement lens 230 is located, which is obtained correspondingly according to the negative correlation correspondence between the first size and the second size, is also barrel-shaped; when the field of view of the lens 10 is rectangular, the light supplement range of the light supplement module 200 where the light supplement lens 230 is located, which is obtained correspondingly according to the negative correlation correspondence between the first size and the second size, is also rectangular.

Referring to fig. 8a and 8b, fig. 8a and 8b are schematic diagrams illustrating a light supplement range a formed by light passing through the light supplement lens 230 shown in fig. 5. Wherein, the dotted line shows the transmission direction of the light. In this embodiment, the field of view of the lens 10 is pincushion-shaped, and the fill lens 230 is obtained by corresponding to the first size and the third size according to the corresponding relationship of the negative correlation with the second size. In this embodiment, after the light is refracted and reflected by the light supplement lens 230, a pillow-shaped light supplement area a corresponding to the field range of the lens 10 can be formed.

Referring to fig. 9 and 10, fig. 9 is a schematic cross-sectional view of the fill lens 230 shown in fig. 5 perpendicular to the optical axis b, and fig. 10 is a schematic view of a field range of the lens 10 of the electronic device shown in fig. 2. In some embodiments of the present application, the first direction includes at least a vertical viewing direction of the lens 10 (Y-axis direction in fig. 10), a horizontal viewing direction of the lens 10 (X-axis direction in fig. 10), and a diagonal viewing direction of the lens 10 (i.e., a diagonal direction of a viewing range of the lens 10). When the first direction is the vertical viewing field direction of the lens 10, the first included angle phi is 0 deg., at this time, the size of the first dimension is d1, and the size of the second dimension is L1; when the second direction is the horizontal viewing field direction of the lens 10, the first included angle phi is 90 degrees, at this time, the size of the first dimension is d2, and the size of the second dimension is L2; when the third direction is the diagonal view field direction of the lens 10, the first included angle Φ is greater than 0 ° and smaller than 90 °, and at this time, the size of the first dimension is d3, and the size of the second dimension is L3. In this embodiment, d2 is greater than d1, and L2 is less than L1; d3 is greater than d2 and L3 is less than L2. In the embodiment shown in fig. 9 and 10, the first included angle Φ is infinite, that is, the size of any direction of any cross section of the light supplement lens 230 is negatively related to the size of the field range of the lens 10 in that direction, so that the light supplement area of the light supplement lamp module 200 can more accurately correspond to the field range of the lens 10, and thus the light supplement lamp module 200 can achieve higher light utilization rate, reduce energy waste, and more reduce stray light outside the field range. Since the size of the lens 10 in each direction is continuously variable within the field of view, and the first included angle Φ is infinite, the size of the fill-in lens 230 in each direction in any cross section is also continuously variable. In this embodiment, the peripheral surface 233 of the fill-in lens 230 is a continuous curved surface, that is, there is no abrupt curvature change on the peripheral surface 233, that is, curvature continuity changes at different positions of the curved surface, so as to ensure that fill-in light in a fill-in light area formed after light reflected by the peripheral surface 233 exits is relatively uniform.

In the embodiment of the present application, when the field range of the lens 10 is pillow-shaped, barrel-shaped or rectangular, the size of the field range of the lens 10 corresponding to the vertical field direction is different from the size of the horizontal field direction, and the size of the diagonal field direction is greater than the size of the vertical field direction and the size of the horizontal field direction, according to the corresponding relationship between the first size and the third size, which are negatively correlated with the second size, the cross section of the obtained fill-in lens 230 perpendicular to the optical axis b and the second surface 232 are all rhomboid. Wherein, the rhomboid is similar to the rhomboid in shape, and the diagonal lines thereof are vertical and have different lengths. In the embodiment of the present application, the diagonal directions of the quasi-diamond shape correspond to the vertical viewing field direction and the horizontal viewing field direction of the lens 10, respectively. Moreover, in the embodiment of the present application, the light supplement module 200 is disposed close to the lens module 100, and the optical axis b of the light supplement module 200 is parallel to the optical axis a of the lens module 100, so as to ensure that the light supplement area of the light supplement module 200 can cover the field range of the lens module 100. It can be understood that, in some embodiments, the optical axis b of the light supplement module 200 and the optical axis a of the lens module 100 form a certain angle, so as to meet the actual light supplement requirement.

In some embodiments, the field range of the lens module 100 is pillow-shaped, barrel-shaped or square, at this time, the size of the field range of the lens module 100 corresponding to the vertical field direction is the same as the size of the horizontal field direction, and when the size of the diagonal field direction is larger than the field range of the vertical field direction and the horizontal field direction, according to the corresponding relationship between the first size and the second size, the cross section of the light compensating lens 230 perpendicular to the optical axis b and the second surface 232 are both square-like. The square-like shape is similar to a square shape, and two diagonal lines of the square-like shape are vertical and have the same length. When the first direction may be any direction, the contour line of the cross section of the rhombus-like or square-like fill lens 230 perpendicular to the optical axis b is a free curve, and the curvature of each position changes continuously.

In the present application, the first surface 231 of the fill-in lens 230 may be circular, elliptical, rhomboid, or square-like, and the peripheral surface 233 transitionally connects the first surface 231 and the second surface 232, that is, the cross section of the fill-in lens 230 perpendicular to the optical axis b gradually changes from the same shape as the first surface 231 to the same shape as the second surface 232 in the direction from the first surface 231 to the second surface 232. For example, in the embodiment shown in fig. 5, the first surface 231 of the fill-in lens 230 is circular, the second surface 232 is rhomboid, and the peripheral surface 233 transitionally connects the first surface 231 and the second surface 232, that is, the cross section of the fill-in lens 230 perpendicular to the optical axis b gradually changes from circular to rhomboid which is the same as the second surface 232 in the direction from the first surface 231 to the second surface 232. Generally, any field of view of the lens module 100 near the optical axis a of the lens module 100 has almost no distortion, i.e. paraxial rays of the lens module 100 can be imaged almost without distortion, so that a circular or rectangular supplementary lighting is suitable for the area of the field of view near the optical axis a; the farther the field range of the lens module 100 is from the optical axis a, the larger the distortion of the deformed position, i.e., the farther the lens module 100 is from the optical axis a, the larger the imaging distortion (barrel distortion or pincushion distortion) is, therefore, the pincushion or barrel fill-in is more suitable for the area farther from the optical axis a. In this embodiment, the first surface 231 is circular, the second surface 232 is a rhomboid, and the peripheral surface 233 is in transitional connection with the first surface 231 and the second surface 232, so that the illuminance distribution in the light compensation area of the light compensation lamp module 200 can correspond to different distortion degrees at different positions in the view field of the lens module 100, and therefore the light compensation requirements at different positions in the view field of the lens module 100 can be met, and the light compensation can be more uniform.

It is understood that, in some embodiments of the present disclosure, when the second surface 232 of the light filling lens 230 and the cross section perpendicular to the optical axis b are rhomboid, the first surface 231 of the light filling lens 230 may also be rhomboid. And, when first face 231 is the class rhombus, two diagonals of first face 231 are the same with two diagonal directions of second face 232 respectively, and are the same with the perpendicular field of view direction and the horizontal field of view direction of lens module 100 respectively, thereby guarantee that the arbitrary cross-section of light filling lens 230 perpendicular to optical axis b is the class rhombus, guarantee that the light filling region of light filling lamp module 200 can match with the field of view scope of lens module 100, promote the optical efficiency of light filling lamp module 200, reduce the external light pollution of field of view.

Referring to fig. 11, fig. 11 is a schematic structural diagram of a fill lens 230 according to another embodiment of the present disclosure. In some embodiments of the present application, still be equipped with on the light filling lens 230 and prevent slow-witted structure 235, can guarantee through preventing slow-witted structure 235 that light filling lens 230 can install to lamp plate 210 with correct direction on to guarantee that the cross-section of light filling lens 230 perpendicular to optical axis b direction and the diagonal direction of second face 232 are corresponding to the perpendicular visual field direction and the horizontal visual field direction of camera lens 10 respectively, guarantee first size and third size and second size negative correlation. In this embodiment, the fool-proof structure 235 includes two protrusions disposed on the first surface 231 and two grooves or holes disposed at corresponding positions on the lamp panel 210. Wherein, the connection line of the two protrusions on the first surface 231 is the diagonal direction of the second surface 232. When light filling lens 230 is fixed in on the worn-out fur 210, two recesses or trompil are located respectively to two archs to guarantee that light filling lens 230 can install to lamp plate 210 with correct direction on.

Referring to fig. 12 and 13, fig. 12 is a schematic cross-sectional view of a fill-in lens 230 according to another embodiment of the present disclosure along an optical axis b, and fig. 13 is a side view of the fill-in lens 230 shown in fig. 12. The difference between this embodiment and the fill-in lens 230 shown in fig. 5 is that: in this embodiment, the bottom wall 2341 of the accommodating cavity 234 is a curved surface, a distance from a boundary of the bottom wall 2341 in the first direction to the second surface 232 is a first distance, and the first distance is positively correlated with the second dimension. Wherein the positive correlation is a change in the same direction. For example, the first distance is positively correlated with the second dimension, i.e., as the second dimension varies in the first direction, the larger the first distance. In some embodiments, the fill lens 230 includes a first portion 230a and a second portion 230b disposed around the first portion 230 a. Specifically, the peripheral edge of the bottom wall 2341 extends along the direction of the optical axis b to form a dummy surface 230c, wherein a portion of the fill-in lens 230 surrounded by the dummy surface 230c is the first portion 230a, and a portion of the fill-in lens 230 between the dummy surface 230c and the peripheral surface 233 of the fill-in lens 230 is the second portion 230 b. The first distance is a thickness of the edge position of the first portion 230a in the first direction. In some embodiments, the first portion 230a and the second portion 230b are integrally formed, and the dummy surface 230c is not an actually existing surface, but is only a surface defined for dividing the first portion 230a and the second portion 230b of the fill lens 230.

In this embodiment, according to the corresponding relationship between the first distance and the positive correlation between the second distance and the second size, the structure of the first portion 230a of the light supplement lens 230 corresponding to the field of view of the lens 10 is obtained, so that the light supplement range formed after the light is emitted through the first portion 230a of the light supplement lens 230 can be substantially the same as the shape of the field of view of the lens 10 corresponding to the light supplement range, and the light supplement range formed after the light is emitted through the first portion 230a of the light supplement lens 230 can cover the field of view of the lens 10 corresponding to the light supplement range, thereby ensuring that the light supplement lamp module 200 can supplement light for each position within the field of view of the lens 10, further improving the light energy utilization rate of the light supplement lamp module 200, further reducing the stray light outside the field of the lens module 100, and reducing light pollution. The light supplement range formed by the light emitted from the first portion 230a of the light supplement lens 230 refers to an area irradiated by the light emitted from the light emitting surface of the light supplement lens after passing through the light supplement lens 230. In some embodiments of the present application, the light energy utilization rate of the light supplement lamp module 200 can reach 80% to 85%, which can be increased by 10% to 15% compared to the light energy utilization rate of the general light supplement lamp module 200.

Referring to fig. 14a and 14b, fig. 14a and 14b are schematic diagrams illustrating a light supplement range formed by light passing through the first portion 230a of the light supplement lens 230 shown in fig. 12. The first portion 230a of the fill lens 230 in fig. 14a and 14b is obtained by corresponding to the field range of the pincushion-shaped lens module 100 according to the corresponding relationship between the first distance and the second size. In this application, the light supplement region obtained through the first portion 230a of the light supplement lens 230 shown in fig. 14a and 14b is pillow-shaped corresponding to the field range of the lens module 100, so that the light supplement lamp module 200 can be ensured to achieve better light supplement for the lens module 100, reduce energy waste, and achieve higher energy utilization rate.

Referring to fig. 15, fig. 15 is a schematic structural diagram of a first portion 230a of the fill lens 230 shown in fig. 14 a. The structure of the first portion 230a of the fill-in lens 230 shown in fig. 15 is obtained according to the field of view range of the lens 10 shown in fig. 10, so that the first distance of the first portion 230a of the fill-in lens 230 shown in fig. 15 is positively correlated with the second size of the field of view range of the lens 10 shown in fig. 10. In the present application, the first direction at least includes a vertical viewing direction of the lens 10, a horizontal viewing direction of the lens 10, and a diagonal viewing direction of the lens 10. When the first direction is the vertical viewing field direction of the lens 10, the first included angle phi is 0 deg., at this time, the first distance is delta 1, and the size of the second dimension is L1; when the second direction is the horizontal viewing field direction of the lens 10, the first included angle phi is 90 degrees, at this time, the first distance is delta 2, and the size of the second dimension is L2; when the third direction is the diagonal viewing direction of the lens 10, the first included angle Φ is greater than 0 ° and less than 90 °, at which time the first distance δ 3 and the second dimension L3 are measured. In the present embodiment, since L2 of the field of view region is smaller than L1, δ 2 of the first portion 230a is larger than δ 1; since L3 of the field of view is greater than L2, δ 3 of the first portion 230a is less than δ 2. In the embodiment shown in fig. 15, the first included angle Φ is infinite, that is, the first distance in any direction of the first portion 230a of the light supplement lens 230 is positively correlated with the second size of the field range of the lens 10 in the direction, so that the light supplement area of the light supplement lamp module 200 can correspond to the field range of the lens 10 more accurately, and thus the light supplement lamp module 200 can achieve higher light utilization rate, reduce energy waste, and reduce more stray light outside the field range. In this embodiment, the thicknesses of the first portion 230a at different positions are continuously changed, that is, the bottom wall 2341 is a continuous curved surface, the curvatures of the positions of the bottom wall 2341 are continuously changed, and there are no positions where the curvatures are abruptly changed, so that the light supplement of the light supplement area formed after the light is emitted through the first portion 230a is more uniform.

In this application, the bottom wall 2341 of the fill lens 230 may be an outer convex surface facing the first surface 231 or an inner concave surface away from the first surface 231. The bottom wall 2341 of the fill lens 230 shown in fig. 15 is an outer convex surface facing the first surface 231, so that the first portion 230a has positive focal power and has the function of converging light. Referring to fig. 16, fig. 16 is a schematic structural diagram of a first portion 230a of a fill lens 230 according to another embodiment of the present disclosure. In this embodiment, the bottom wall 2341 of the light-compensating lens 230 is an inner concave surface far away from the first surface 231, so that the first portion 230a has negative focal power and has the function of diverging light. The light supplement range of the same light formed by the first portion 230a of the light supplement lens 230 shown in fig. 16 is larger than the light supplement range formed by the first portion 230a of the light supplement lens 230 shown in fig. 15.

In some embodiments, when the first distance of the first portion 230a is positively correlated to the second dimension and the cross section of the fill-in lens 230 perpendicular to the optical axis b is not rhomboid, the fill-in range of the fill-in lamp module 200 can also fill in the field of view of the lens module 100. In addition, since the size and shape of the light supplement region of the first portion 230a can be the same as those of the field of view of the lens module 100, the light energy utilization rate of the light supplement lamp module 200 can be improved, and stray light outside the field of view can be reduced. For example, referring to fig. 17, fig. 17 is a schematic structural diagram of a fill lens 230 according to another embodiment of the present application. The difference between this embodiment and the fill-in lens 230 shown in fig. 10 is that: in the present embodiment, the light compensation lens 230 has a rotationally symmetric truncated cone-shaped structure with the optical axis b as an axis. That is, the cross section of the fill lens 230 perpendicular to the optical axis b is circular, rather than diamond-like. In this embodiment, since the bottom wall 2341 is a free-form surface, the light supplement range of the light rays emitted through the bottom wall 2341 matches the field range of the lens 10, that is, the shape and size of the light supplement range of the light rays emitted through the bottom wall 2341 are substantially the same as those of the field range of the lens 10. That is, when the field of view of the lens 10 is pillow-shaped, the light supplement range of the light emitted from the bottom wall 2341 is also pillow-shaped; when the field of view scope of camera lens 10 is barrel-shaped, the light filling scope of the light of diapire face 2341 outgoing also is barrel-shaped to also can realize that the luminous energy high efficiency of light filling lamp module 200 utilizes, and can avoid the extraterrestrial veiling glare.

The inner surface of the light reflecting housing 230d is a circumferential surface 233 for reflecting a portion of the light emitted from the light source 210. The bottom of the light reflecting housing 230d is contoured to define a second face 232 and the top of the light reflecting housing 230d is contoured to define a first face 231. The light-exiting lens 230e is fixed to a side of the light-reflecting housing 230d close to the first surface 231. Specifically, in some embodiments, the light-emitting lens 230e is fixed in the light-reflecting shell 230d through the bracket 230f, a part of the light emitted by the light source 220 is refracted by the light-emitting lens 230e for emitting light, and a part of the light is reflected by the light-reflecting shell 230d for emitting light. In this embodiment, the support 230f is a transparent support 230f or a support 230f formed by a thin rod with a small volume, so as to avoid the support 230f from blocking the light emitted by the light source 220.

In this embodiment, the structure of the light-emitting lens 230e may be similar to the structure of the first portion 230a of the fill lens 230 shown in fig. 15 and 16. That is, the edge thickness of the light-emitting lens 230e in the first direction is the first thickness, and the first thickness is positively correlated with the second size, so as to ensure that the shape of the light supplement range formed by the light refracted by the light-emitting lens 230e, the shape and the size of the view field range of the lens 10 are basically the same, so that the light supplement range of the light supplement lamp module 200 is basically coincided with the view field range of the lens 10, the light utilization rate of the light supplement lamp module 200 is improved, and the out-of-field stray light outside the view field range of the lens 10 is reduced.

In the present embodiment, the inner surface of the light reflecting housing 230d has the same structure as the circumferential surface 233 of the fill lens 230 shown in fig. 5. In this embodiment, the section of the light supplement lens 230 perpendicular to the optical axis b is: the reflective housing 230d is sectioned by a plane perpendicular to the optical axis b, and the inner surface of the reflective housing 230d is located on the plane. The size of the cross section of the light supplement lens 230 perpendicular to the optical axis b or the second surface 232 in the first direction is a first size, the first size is negatively related to a second size, the size of the second surface 232 in the first direction is a third size, and the third size is also negatively related to the second size, so that the size and the shape of a light supplement range formed by light rays emitted by the light source 220 after being reflected and emitted by the light reflecting shell 230d are basically the same as the field range of the lens module 100, thereby further improving the light supplement efficiency of the light supplement lens 230 and reducing stray light outside the field range.

It is understood that in other embodiments of the present application, the fill lens 200 may only include the light reflecting shell 230d shown in the embodiment of fig. 18, and the light exiting lens 230e is not included. Alternatively, in some embodiments, the light filling lens 200 includes the light exiting lens 230e shown in the embodiment of fig. 17, and the light reflecting shell 230d included in the light filling lens 200 may have another structure different from that of the embodiment shown in fig. 18. For example, the space defined by the inner surface of the light reflecting housing 230d may have a truncated cone shape or an elliptical truncated cone shape.

For example, in some embodiments, when the electronic device 1000 is a mobile phone, the mobile phone includes a lens module 100 that is a wide-angle (wide) lens and a fill-in light module 200 that fills in light for a field range of the wide-angle lens. The field of view of the wide-angle lens is generally pincushion shaped. The light supplement lens 230 of the light supplement lamp module 200 of the present embodiment is designed to correspond to the field of view of the wide-angle lens, so that the light supplement range of the light supplement lamp module 200 of the present embodiment is substantially the same as the shape and size of the field of view of the wide-angle lens of the present embodiment, thereby achieving better illumination of the field of view of the wide-angle lens, improving the light utilization of the light supplement lamp module 200, reducing the energy waste, and reducing the stray light outside the field of view more.

In some embodiments, when the lens module 100 is a zoom lens, the field range of the lens module 100 can be changed according to the focal length of the lens module 100. Referring to fig. 20, fig. 20 is a shape diagram of a field of view range of the zoom lens at different focal lengths. When the focal length of the zoom lens is adjusted to the wide end, the field of view formed by the lens module 100 is an area surrounded by the outline a in fig. 20, and the shape of the field of view is pillow-shaped; when the focal length of the zoom lens is adjusted to the tele end, the field of view formed by the lens module 100 is an area surrounded by the outline B in fig. 20, and the shape of the field of view is barrel-shaped; when the focal length of the zoom lens is between the wide end and the tele end, the field range formed by the lens module 100 is the area enclosed by the contour C in fig. 20. In the process of adjusting the focal length of the zoom lens from the wide end to the tele end, the shape of the area formed by the contour C is in barrel-shaped transition from the pillow shape surrounded by the contour A to the barrel shape surrounded by the contour B. Because the field of view scope of zoom is in the shape and the size difference of the field of view scope of the focus section of difference, consequently, in some embodiments of this application, corresponding to the different focus sections of zoom, match and use different light filling lens 230 to make the light filling lamp module group can be accurate carry out accurate key illumination to the field of view scope of zoom, improve the light utilization ratio of light filling lamp module group 200, reduce the waste of energy, and more reduce the miscellaneous light outside the field of view scope. For example, referring to fig. 21, fig. 21 is a schematic structural diagram of a fill-in lamp module 200 according to another embodiment of the present disclosure. The light supplement lamp module 200 of the present embodiment is a zoom lens for supplementing light. In this embodiment, the light supplement lamp module 200 has two light sources 220 and two light supplement lenses 230. The two light sources 220 and the two light supplement lenses 230 are both installed on the lamp panel 210, the light sources 220 correspond to the light supplement lenses 230 one by one, and the two light supplement lenses 230 are respectively matched with the light supplement range of the wide end and the view field range of the tele end of the zoom lens. When the focal length of the zoom lens is adjusted to the wide end, the light source 220 corresponding to the fill-in lens 230 matched with the field range of the wide end is turned on, so that the fill-in lamp module 200 generates a fill-in range with the shape and size substantially the same as the field range of the wide end; when the focal length of the zoom lens is adjusted to the tele end, the light source 220 corresponding to the fill-in lens 230 matched with the field range of the tele end is turned on, so that the fill-in lamp module generates a fill-in range with the shape and size substantially the same as the field range of the tele end. It should be noted that, according to actual needs, the number of the light supplement lens 230 and the light sources 220 included in the light supplement lamp module 200 may be three or more. For example, for a part of image recognition styles, the requirement for fill light at an intermediate magnification between the Wide end and the Tele end is high, and therefore, the fill light lens 230 corresponding to the fill light module 200 needs to include at least one fill light lens 230 in addition to two fill light lenses 230 respectively matching with a fill light range of the Wide end and a fill light range of the Tele end of the zoom lens, and the fill light lens 230 can match with a field range formed by the zoom lens when the focal length is between the Wide end and the Tele end of the zoom lens, so as to respectively match with field ranges formed when the focal length of the zoom lens is between the Wide end and the Tele end through three or more fill light lenses 230. Or, in some embodiments, when the zoom magnification of the zoom lens is small, and the focal length of the zoom lens is located at the Wide end, the Tele end, or between the Wide end and the Tele end, the field range formed by the zoom lens is small, and in order to reduce the cost and simplify the manufacturing process, only one fill-in lens 230 may be configured in the fill-in lamp module 200. For example, when the zoom magnification of the zoom lens is smaller than 3 ×, the fill-in light module 200 may only configure the fill-in lens 230 corresponding to the field range where the focal length of the zoom lens is located at the wide end.
