Fill lights and electronic equipment

[0001] Cross-reference of related applications

[0002] This application claims priority to Chinese Patent Application No. 202510305834.1, filed on March 14, 2025, entitled “Supplemental Light and Electronic Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of optical device technology, specifically relating to a fill light and electronic device. Background Technology

[0004] As the imaging capabilities of mobile phones and other electronic devices continue to improve, the demand for taking photos with these devices is also increasing, leading to a wide variety of shooting scenarios. However, in low-light environments and night scenes, it's difficult to capture clear photos, and video recording or live streaming also offers a less than ideal experience. Therefore, electronic devices are equipped with supplemental lights to provide additional illumination for shooting.

[0005] However, electronic devices in related technologies typically have multiple cameras with different focal lengths to improve shooting performance, and the shooting range of cameras with different focal lengths varies. The supplementary lighting of these electronic devices can only emit a single spot of light with fixed brightness and illumination range. This single spot of light is insufficient to meet the supplementary lighting needs of cameras with different focal lengths, resulting in poor supplementary lighting performance of the electronic devices. Summary of the Invention

[0006] The purpose of this application is to provide a supplementary light and electronic device that can solve the technical problem of poor supplementary lighting performance of electronic devices.

[0007] In a first aspect, this application discloses a supplementary lighting lamp, comprising: a light distribution element having a light-emitting surface and a light-incident surface disposed opposite to each other, the light-incident surface including a first light-distributing textured surface and a second light-distributing textured surface disposed side by side; a first light-emitting source and a second light-emitting source, the first light-emitting source being disposed opposite to the first light-distributing textured surface; the second light-emitting source being disposed opposite to the second light-distributing textured surface, the light emitted by the first light-emitting source and the second light-emitting source passing through their corresponding light-distributing textured surfaces and exiting from the light-emitting surface; wherein the texture structures of the first light-distributing textured surface and the second light-distributing textured surface are different, and / or the distances between the first light-emitting source and the second light-emitting source and their corresponding light-distributing textured surfaces are different, so that the illuminance and viewing angle range of the light spots projected by the first light-emitting source and the second light-emitting source after passing through their corresponding light-distributing textured surfaces are different.

[0008] Secondly, this application discloses an electronic device, including a housing, a circuit board, a camera module, and the aforementioned supplementary light. The camera module and the circuit board are both disposed on the housing, the light distribution element is disposed on the housing, and the first light source and the second light source are both disposed on the circuit board. The camera module includes a first camera and a second camera, which are different cameras. When the first camera is in supplementary lighting mode, the first light source is turned on; when the second camera is in supplementary lighting mode, the second light source is turned on.

[0009] In this embodiment, the light-incident surface of the light-distributing element includes a first light-distributing textured surface and a second light-distributing textured surface arranged side by side. A first light-emitting source is positioned opposite to the first light-distributing textured surface, and a second light-emitting source is positioned opposite to the second light-distributing textured surface. The texture structures on the first and second light-distributing textured surfaces are different, and / or the distances between the first and second light-emitting sources and their corresponding light-distributing textured surfaces are different, so that the illuminance and viewing angle range of the light spots projected by the first and second light-emitting sources after passing through their corresponding light-distributing textured surfaces are different. The supplementary light disclosed in this application can form a variety of different light spots, and the illuminance and viewing angle range of these different light spots are all different. Therefore, the supplementary light in this application can meet the supplementary lighting needs of cameras with different focal lengths in electronic devices, thereby improving the supplementary lighting performance of electronic devices and thus enabling electronic devices to have better shooting performance.

Detailed Implementation

[0027] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The supplementary lighting and electronic equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0030] Please refer to Figures 1 to 14. This application discloses a supplementary light 100, which is used in electronic devices. The disclosed supplementary light 100 includes a light distribution element 110, a first light source 121, and a second light source 122.

[0031] The light distribution element 110 has a light-emitting surface 111 and a light-incident surface 112 arranged opposite to each other. The light-incident surface 112 includes a first light-distributing textured surface 1121 and a second light-distributing textured surface 1122 arranged side by side. A first light-emitting light source 121 is arranged opposite to the first light-distributing textured surface 1121, and a second light-emitting light source 122 is arranged opposite to the second light-distributing textured surface 1122. The light emitted by the first light-emitting light source 121 and the second light-emitting light source 122 passes through their corresponding light-distributing textured surfaces and is emitted from the light-emitting surface 111. The material of the light distribution element 110 can be PC (Polycarbonate), but other materials are also possible and are not limited herein.

[0032] During the operation of the supplementary light 100, when the first light source 121 is lit, the light emitted by the first light source 121 is distributed through the first light distribution texture surface 1121 and then emitted from the light-emitting surface 111. When the second light source 122 is lit, the light emitted by the second light source 122 is distributed through the second light distribution texture surface 1122 and then emitted from the light-emitting surface 111. Here, the light emitted by the first light source 121 and the light emitted by the second light source 122 can be emitted through the same area of ​​the light-emitting surface 111. Alternatively, the light-emitting surface 111 has a first light-emitting area and a second light-emitting area arranged side by side, with the first light-emitting area opposite to the first light distribution texture surface 1121, and the light emitted by the first light source 121 is distributed through the first light distribution texture surface 1121 and then emitted from the first light-emitting area. The second light-emitting region is positioned opposite to the second light-distribution texture surface 1122. The light emitted by the second light-emitting source 122 is distributed by the second light-distribution texture surface 1122 and then emitted from the second light-emitting region.

[0033] In the embodiments disclosed in this application, the texture structures on the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122 are different. Since the texture structures of the two light-distributing textures are different, the illuminance and viewing angle range of the light spots projected by the first light-emitting light source 121 and the second light-emitting light source 122 after passing through their respective light-distributing texture surfaces are also different. Here, the viewing angle range of the light spot refers to the range that the projected light spot can illuminate, while the illuminance of the light spot refers to the brightness of the light spot. For example, when the angular contraction of the first light-distributing texture surface 1121 with the light emitted by the first light-emitting light source 121 is small, the radiation angle of the light emitted by the first light-emitting light source 121 after passing through the first light-distributing texture surface 1121 is large, therefore the viewing angle range of the projected light spot is large, and the illuminance of the light spot is small. Because the viewing angle range of the light spot increases, its brightness decreases. When the angle subtended by the second light-distributing texture surface 1122 on the light emitted by the second light-emitting source 122 is significantly reduced, the radiation angle of the light emitted by the second light-emitting source 122 after passing through the second light-distributing texture surface 1122 is smaller. Therefore, the viewing angle of the projected light spot is smaller, the light is more concentrated, and the illuminance of the light spot is larger. At this time, the viewing angle of the light spot becomes smaller, and the brightness of the light spot is larger. Since the viewing angle of the light spot transmitted by the first light-emitting source 121 through the first light-distributing texture surface 1121 is larger, it can illuminate a wider range. Therefore, the light spot transmitted by the first light-emitting source 121 through the first light-distributing texture surface 1121 can provide supplementary lighting for cameras with a large field of view, such as wide-angle cameras. On the other hand, the viewing angle of the light spot transmitted by the second light-emitting source 122 through the second light-distributing texture surface 1122 is smaller, but the brightness is higher, so the illumination distance is farther. Therefore, the light spot transmitted by the second light-emitting source 122 through the second light-distributing texture surface 1122 can provide supplementary lighting for cameras with a smaller field of view, such as telephoto cameras.

[0034] Of course, the embodiments disclosed in this application are not limited to different texture structures on the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122. They can also differ in the distance between the first light-emitting light source 121 and the second light-emitting light source 122 and their corresponding light-distributing texture surfaces. For example, when the structures of the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122 are the same, the distance between the first light-distributing texture surface 1121 and the first light-emitting light source 121 is smaller than the distance between the second light-distributing texture surface 1122 and the second light-emitting light source 122. Since the distance between the first light-distributing texture surface 1121 and the first light-emitting light source 121 is closer, the viewing angle range of the light spot transmitted by the first light-emitting light source 121 through the first light-distributing texture surface 1121 is larger. Conversely, the distance between the second light-distributing texture surface 1122 and the second light-emitting light source 122 is farther, therefore the viewing angle range of the light spot transmitted by the second light-emitting light source 122 through the second light-distributing texture surface 1122 is smaller.

[0035] In another scheme, the texture structures on the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122 are different, and the distances between the first light-emitting light source 121 and the second light-emitting light source 122 and their corresponding light-distributing texture surfaces are also different. In this case, the difference in light spots can be increased by the difference in distance and texture structure.

[0036] In the embodiments disclosed in this application, the fill light 100 can form a variety of different light spots, and the illuminance and viewing angle range of the various different light spots are different. Therefore, the fill light 100 in this application can meet the fill light requirements of cameras with different focal lengths in electronic devices, thereby improving the fill light performance of electronic devices and enabling electronic devices to have better shooting performance.

[0037] Furthermore, the supplementary light 100 disclosed in this application achieves supplementary lighting at multiple focal lengths without increasing the number of supplementary lights 100 or the number of light-transmitting areas 210 on the electronic device. Therefore, in terms of appearance, the electronic device still only has one supplementary light 100, thus improving the appearance performance of the electronic device. At the same time, the reduced number of openings in the electronic device also helps to improve its waterproof and dustproof performance.

[0038] In addition, this application can achieve different supplementary light spots by using different texture structures of the light distribution texture surface and / or different distances between the light distribution texture surface and its corresponding light source. Therefore, the optical structure is simple and the cost is low.

[0039] In the above scheme, the texture structure of the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122 can be an arc-shaped convex surface or multiple sequentially arranged tooth-shaped structures. Of course, the texture structure on the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122 can also be other structures, which are not limited here. The first light-distributing texture surface 1121 and the second light-distributing texture surface 1122 can both be arc-shaped convex surfaces. In this case, the curvature or radius of the two arc-shaped convex surfaces is different, so that the radiation angle of the two light-distributing texture surfaces is different. Alternatively, the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122 can both include multiple tooth-shaped structures. In this case, the tooth width, tooth height, and sway angle of the tooth-shaped structure on the first light-distributing texture surface 1121 are different from the tooth width, tooth height, and sway angle of the tooth-shaped structure on the second light-distributing texture surface 1122, so that the radiation angle of the two light-distributing texture surfaces is different.

[0040] In another optional embodiment, the first light-distributing texture surface 1121 may be rotationally symmetrical about the central optical axis of the first light-emitting source 121. Here, the central optical axis of the first light-emitting source 121 refers to the optical axis at the center of the first light-emitting source 121 or the physical center line of the first light-emitting source 121. The central optical axis of the first light-emitting source 121 is shown as O1 in Figures 1 and 5. The second light-distributing texture surface 1122 may be rotationally symmetrical about the central optical axis of the second light-emitting source 122. Here, the central optical axis of the second light-emitting source 122 refers to the optical axis at the center of the second light-emitting source 122 or the physical center line of the second light-emitting source 122. The central optical axis of the second light-emitting source 122 is shown as O2 in Figures 1 and 5.

[0041] Both the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122 may include a first light-incident structure 11201 and a second light-incident structure 11202. The second light-incident structure 11202 may be arranged around the first light-incident structure 11201. The first light-incident structure 11201 is an arc-shaped convex surface. The second light-incident structure 11202 may include a plurality of annular teeth 11202a, which are continuously arranged in a direction away from the first light-incident structure 11201. Here, the plurality of annular teeth 11202a being continuously arranged in a direction away from the first light-incident structure 11201 refers to the direction from the center of the first light-distributing texture surface 1121 or the second light-distributing texture surface 1122 to its edge.

[0042] Specifically, the first light-incident structure 11201 is an arc-shaped convex surface, protruding towards one side of its corresponding first light-emitting source 121 or second light-emitting source 122. At this time, the first-angle light rays from the first light-emitting source 121 or second light-emitting source 122 are emitted from the light-emitting surface 111 after passing through the first light-incident structure 11201. The arc-shaped convex surface has a relatively precise angular contraction effect on light rays diverging at small angles. Therefore, by setting the first light-incident structure 11201 as an arc-shaped convex surface, it is possible to better contract small-angle light rays.

[0043] When the divergence angle of the light from the first light source 121 or the second light source 122 further increases, the control precision of the arc-shaped convex surface deteriorates, making it difficult to control the light's dispersion or diffusion. At this time, the second-angle light from the first light source 121 or the second light source 122 is emitted from the light-emitting surface 111 after passing through the second light-incident structure 11202. Since each annular tooth 11202a has two opposing sidewalls, the light first enters through one sidewall, which refracts the incident light. The refracted light is then reflected by the other sidewall. Therefore, through one refraction and one reflection, the light can be effectively dispersed or dispersed, thereby further improving the control precision of the light.

[0044] In this scheme, the first light distribution texture surface 1121 and the second light distribution texture surface 1122 each have two light distribution areas. Each light distribution area adopts a different light distribution structure for light at different angles, which can help improve the light distribution accuracy of each light distribution texture surface and thus improve the supplementary lighting performance of the supplementary light lamp 100.

[0045] In the above scheme, the first light-incident structure 11201 on the first light-distribution texture surface 1121 and the second light-distribution texture surface 1122 are different. Alternatively, the second light-incident structure 11202 on the first light-distribution texture surface 1121 and the second light-distribution texture surface 1122 are different. Furthermore, both the first light-incident structure 11201 and the second light-incident structure 11202 on the first light-distribution texture surface 1121 and the second light-distribution texture surface 1122 are different.

[0046] In another alternative scheme, at least one of the following three properties of the annular teeth 11202a on the first light-distribution texture surface 1121 and the second light-distribution texture surface 1122 is different: tooth width, tooth height, and swing angle. Here, tooth height refers to the distance between the root and tip of each annular tooth 11202a. In Figure 2, h1 represents the tooth height of the annular tooth 11202a on the first light-distribution texture surface 1121, and in Figure 3, h2 represents the tooth height of the annular tooth 11202a on the second light-distribution texture surface 1122. Tooth width refers to the width of each annular tooth 11202a, which is the distance between the roots or tips of the teeth on opposite sides of each annular tooth 11202a. In Figure 2, w1 represents the tooth width of the annular tooth 11202a on the first light-distribution texture surface 1121, and in Figure 3, w2 represents the tooth width of the annular tooth 11202a on the second light-distribution texture surface 1122. The tilt angle refers to the inclination angle of the annular tooth 11202a, which can be characterized by one side of the annular tooth 11202a. Alternatively, the tilt angle of each annular tooth 11202a can be characterized by the tilt angle of the line connecting the midpoint between the two tooth roots and the tooth tip of each annular tooth 11202a. As shown in Figure 2, a1 is the line connecting the midpoint between the two tooth roots and the tooth tip of the annular tooth 11202a on the first light distribution texture surface 1121. As shown in Figure 3, a2 is the line connecting the midpoint between the two tooth roots and the tooth tip of the annular tooth 11202a on the second light distribution texture surface 1122. In one embodiment, the light-incident surface 112 can be used as a reference surface, and the tilt angle of a1 relative to the light-incident surface 112 is the tilt angle of the annular tooth 11202a on the first light distribution texture surface 1121. The tilt angle of a2 relative to the light-incident surface 112 is the tilt angle of the annular tooth 11202a on the second light distribution texture surface 1122. Alternatively, in another embodiment, since the central optical axis of the first light-emitting source 121 is parallel to the central optical axis of the second light-emitting source 122, the tilt angle of a1 relative to the central optical axis of the first light-emitting source 121 is the tilt angle of the annular tooth 11202a on the first light-distribution texture surface 1121. Similarly, the tilt angle of a2 relative to the central optical axis of the second light-emitting source 122 is the tilt angle of the annular tooth 11202a on the second light-distribution texture surface 1122. The tilt angles in this application can be characterized by the tilt angles of a1 and a2 relative to the incident light surface 112.

[0047] In an optional embodiment, the first light-incident structure 11201 on the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122 are identical, meaning that the surface shape and size of the first light-incident structure 11201 on both light-distributing texture surfaces are the same. The tooth width and tooth height of the annular tooth 11202a on the first light-distributing texture surface 1121 are the same as those on the second light-distributing texture surface 1122. The swing angle of the annular tooth 11202a on the first light-distributing texture surface 1121 is greater than that on the second light-distributing texture surface 1122. In this scheme, by adjusting the swing angle of the annular tooth 11202a on the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122, different illuminance and viewing angle ranges of the light spot are achieved. This scheme has a simple structure and is easy to manufacture.

[0048] In the above scheme, the annular teeth 11202a on the first light distribution texture surface 1121 and the annular teeth 11202a on the second light distribution texture surface 1121 differ only in their tilt angle. That is, all the annular teeth 11202a on the first light distribution texture surface 1121 have the same tooth height, tooth width, and tilt angle. Similarly, all the annular teeth 11202a on the second light distribution texture surface 1122 have the same tooth height, tooth width, and tilt angle.

[0049] In the scheme shown in Figure 1, the swing angles of the annular teeth 11202a on the first light distribution texture surface 1121 and the second light distribution texture surface 1121 are different. All annular teeth 11202a on the first light distribution texture surface 1121 have the same tooth height, tooth width, and swing angle. All annular teeth 11202a on the second light distribution texture surface 1122 have the same tooth height, tooth width, and swing angle. In a specific scheme, the specific data of the supplementary light 100 shown in Figure 1 are shown in Table 1 below.

[0050] Table 1

[0051] The distance from the light distribution texture to the corresponding light source can be understood as the distance between the highest point of the first light-incident structure 11201 and the light-emitting surface of the corresponding light source. As shown in Figure 1, g1 is the distance between the first light distribution texture surface 1121 and the first light source 121, and g2 is the distance between the second light distribution texture surface 1122 and the second light source 122. As shown in Figure 5, g3 is the distance between the first light distribution texture surface 1121 and the first light source 121, and g4 is the distance between the second light distribution texture surface 1122 and the second light source 122. Of course, the tooth width and tooth height of the annular teeth 11202a of the first and second light distribution surfaces can fluctuate within ±0.05 mm. The swing angle can fluctuate within ±15 degrees. The distance from the light distribution texture to the corresponding light source can fluctuate within ±0.2 mm. This paper only describes one specific light distribution texture structure; of course, the textures on the first and second light distribution texture surfaces 1121 and 1122 can have other dimensions, which are not limited in this paper.

[0052] In another embodiment, as shown in Figure 5, the diameter of the orthographic projection of the first light-incident structure 11201 on the first light-distribution texture surface 1121 is smaller than the diameter of the orthographic projection of the first light-incident structure 11201 on the second light-distribution texture surface 1122. Along the radial direction of the second light-distribution texture surface 1122, the distance between the tooth tip of the annular tooth 11202a of the second light-distribution texture surface 1122 and the light-emitting surface 111 gradually increases. Here, the radial direction of the second light-distribution texture surface 1122 refers to the direction extending from the center of the second light-distribution texture surface 1122 to its edge.

[0053] In this scheme, the diameter of the orthographic projection of the arcuate convex surface on the first light distribution texture surface 1121 is smaller than the diameter of the orthographic projection of the arcuate convex surface on the second light distribution texture surface 1122. Therefore, the light-incident aperture of the arcuate convex surface on the second light distribution texture surface 1122 is larger, which allows the arcuate convex surface on the second light distribution texture surface 1122 to collimate more light rays. This further improves the center brightness of the light spot transmitted by the second light distribution texture surface 1122, and thus further improves the illuminance of the light spot. Furthermore, since the light-emitting surface 111 serves as the reference surface, the distance between the tooth tip of the annular tooth 11202a on the second light-distributing texture surface 1122 and the light-emitting surface 111 gradually increases. This can be understood as the tooth tip of the outer annular tooth 11202a protruding beyond the tooth tip of the inner annular tooth 11202a. This prevents the outer annular tooth 11202a from being blocked by the inner annular tooth 11202a, thus further improving the utilization rate of light and enhancing the brightness of the transmitted light spot. Therefore, the above structure enables the second light-distributing texture surface 1122 to transmit a light spot with a small supplementary light range and extremely high illuminance at the center, thereby meeting the supplementary light requirements of a telephoto camera.

[0054] As shown in Figure 6, w3 is the width of the arc-shaped convex surface on the second light distribution texture surface 1122, which can also be understood as the diameter of the orthographic projection of the arc-shaped convex surface. The widths of the arc-shaped convex surfaces of the first light distribution texture surface 1121 and the second light distribution texture surface 1122 in Figure 1, as well as the width of the arc-shaped convex surface of the first light distribution texture surface 1121 in Figure 6, can all be 0.3 mm. The dimension of w3 can be 0.5916 mm. Of course, the dimension of w3 can fluctuate within ±0.2 mm.

[0055] In one embodiment, the tooth height, tooth width, and swing angle of all the annular teeth 11202a on the second light-distributing texture surface 1122 can be the same. In this case, the distance between the tooth tip of the annular teeth 11202a and the light-emitting surface 111 can be gradually increased by adjusting the position of each annular tooth 11202a along the central optical axis of the second light-emitting light source 122.

[0056] In another optional embodiment, the tooth width and tooth height of any annular tooth 11202a on the second light distribution texture surface 1122 are both greater than the tooth width and tooth height of any annular tooth 11202a on the first light distribution texture surface 1121. In this scheme, the tooth width and tooth height of any annular tooth 11202a on the second light distribution texture surface 1122 are larger, thus further improving the light contraction performance, which is beneficial for further reducing the light spot range and increasing the brightness of the light spot.

[0057] Optionally, as shown in Figure 6, the tooth width and tooth height of the annular tooth 11202a of the first light-distributing texture surface 1121 can be about 0.15 mm, while the tooth width and tooth height of the annular tooth 11202a of the second light-distributing texture surface 1122 can be between 0.3 mm and 0.4 mm. Therefore, the tooth width and tooth height of the annular tooth 11202a of the second light-distributing texture surface 1122 can be twice the tooth width and tooth height of the annular tooth 11202a of the first light-distributing texture surface 1121.

[0058] In another alternative scheme, the tooth width, tooth height, and swing angle of any adjacent annular teeth 11202a on the second light distribution texture surface 1122 are all different. That is, each annular tooth 11202a on the second light distribution texture surface 1122 is different. In this scheme, by individually designing the tooth shape of the annular teeth 11202a at each position on the second light distribution texture surface 1122, the light at each position can be precisely controlled, which is beneficial to further reduce the spot size and increase the brightness of the spot, achieving an ultra-high brightness spot effect.

[0059] In one specific scheme, the specific data of the second light distribution texture surface 1122 shown in Figure 6 are shown in Table 2 below.

[0060] Table 2

[0061] Point O, as mentioned above, is the origin of the coordinate system. Point O can be the highest point of the arcuate convex surface of the second light-distributing texture surface 1122, or it can be understood as the intersection of the central optical axis of the second light-emitting light source 122 and the arcuate convex surface. A, C, E, G, I, K, and M are the coordinates of the root or base of each annular tooth 11202a of the second light-distributing texture surface 1122, while B, D, F, H, J, L, and N are the coordinates of the tip of each annular tooth 11202a of the second light-distributing texture surface 1122. A continuous tooth profile can be obtained through the coordinates of the tip and root of each annular tooth 11202a. Rotating this tooth profile around the central optical axis of the second light-emitting light source 122 for one revolution yields the second light-incident structure 11202 in this application. The coordinates mentioned above can fluctuate within ±0.05 mm.

[0062] In another alternative embodiment, the light-incident surface 112 may further include a sensor photosensitive area 1123, which may be located between the first light distribution texture surface 1121 and the second light distribution texture surface 1122. The supplementary light 100 may further include a spectral sensor 130, which is disposed opposite to the sensor photosensitive area 1123.

[0063] In the specific operation process, ambient light enters the light distribution element 110 through the light-emitting surface 111, and is then received by the spectral sensor 130 after passing through the photosensitive area 1123 of the sensor. The spectral sensor is responsible for receiving ambient light, and the spectral sensor 130 is responsible for receiving ambient light and sensing external spectral information, thereby improving the color performance of the photo.

[0064] This solution can further improve the shooting performance of electronic devices. Furthermore, because the texture structures on the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122 are different, the seams at the boundaries of the textured areas cannot be symmetrical. This phenomenon does not affect optical performance, but visually it causes strong reflections or a jagged appearance in the seam area, thus reducing the appearance of the supplementary light 100. The sensor photosensitive area 1123 is located between the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122, thus separating them. Even when the sensor photosensitive area 1123 is not textured (i.e., when it is planar), a planar area is provided at the junction of textures in different areas, which can solve the problem of strong reflections or a jagged appearance, thus improving the appearance of the supplementary light 100.

[0065] The specific structure and working principle of the spectral sensor 130 in the above scheme are not limited in this article.

[0066] In the embodiments disclosed in this application, the first light-distributing texture surface 1121, the second light-distributing texture surface 1122, and the sensor photosensitive area 1123 can share the same area of ​​the light-emitting surface 111. Alternatively, the light-emitting surface 111 has a first light-emitting area, a second light-emitting area, and a third light-emitting area, wherein the first light-emitting area is disposed opposite to the first light-distributing texture surface 1121, the second light-emitting area is disposed opposite to the second light-distributing texture surface 1122, and the third light-emitting area is disposed opposite to the sensor photosensitive area 1123.

[0067] However, in order to allow more external light to enter the photosensitive area 1123 of the spectral sensor 130, a light-controlling texture 1123a is usually provided. For example, as shown in Figure 9, a toothed light-controlling texture 1123a is provided on the photosensitive area 1123 of the sensor to meet the light distribution requirements of the spectral sensor 130. At this time, the photosensitive area 1123 of the sensor is no longer a planar structure. As shown in Figure 10, the seam at the boundary of the texture area between the light-controlling texture 1123a on the photosensitive area 1123 and the first light distribution texture surface 1121 and the second light distribution texture surface 1122 cannot be symmetrical. Therefore, visually, it will cause strong reflection or a rough visual effect in the seam area, thus reducing the appearance performance of the supplementary light 100.

[0068] Based on this, in another alternative scheme, as shown in Figures 11 and 13, a separating area 114 is provided at the junction of the sensor photosensitive area 1123 and its adjacent light-distributing texture surface. The separating area 114 is used to separate the light-controlling texture 1123a on the sensor photosensitive area 1123 from the texture structure on its adjacent light-distributing texture surface. In this scheme, a narrow area is provided at the junction of textures in different areas. This area can separate the two joined textures, thereby solving the problem of strong visual reflection or roughness, thus improving the appearance performance of the supplementary light 100.

[0069] In the above scheme, a rectangular plane can be provided between the junction of the sensor photosensitive area 1123 and its adjacent light-distribution texture surface. Alternatively, when setting the first light-distribution texture surface 1121, the second light-distribution texture surface 1122, and the sensor photosensitive area 1123, the first light-distribution texture surface 1121 and the sensor photosensitive area 1123 are spaced apart by a certain distance to form a plane. The second light-distribution texture surface 1122 and the sensor photosensitive area 1123 are also spaced apart by a certain distance to form a plane. Alternatively, the edge of the sensor photosensitive area 1123 has a first region 1141, and the edge of the light-distribution texture surface adjacent to the sensor photosensitive area 1123 has a second region 1142. The first region 1141 and the second region 1142 are joined to form the separating area 114. Here, the first region 1141 can be understood as a reserved area without texture at the edge of the sensor photosensitive area 1123. Similarly, the second region 1142 is an untextured area reserved at the edge of the first light-distribution texture surface 1121 or the second light-distribution texture surface 1122. As shown in Figures 11 and 12, the first region 1141 and the second region 1142 are planar regions. The width shown by b1 is the width of the dividing area 114 formed by the first region 1141 and the second region 1142. The width of b1 can be greater than 0 and less than or equal to 0.5 mm. Preferably, the width of b1 can be 0.1 mm.

[0070] Alternatively, the first region 1141 is the area where the edge of the sensor's photosensitive area 1123 is fogged. That is, the entire area of ​​the sensor's photosensitive area 1123 is provided with a light-controlling texture 1123a, but a certain width of the edge of the sensor's photosensitive area 1123 is fogged to reduce its light transmittance, thereby reducing strong visual reflection or a rough appearance. Similarly, the second region 1142 is the fogged area at the edge of either the first light-distributing texture surface 1121 or the second light-distributing texture surface 1122. As shown in Figures 13 and 14, the first region 1141 and the second region 1142 are fogged areas. The fogging effect can be achieved through processes such as laser processing or etching. The width shown by b2 is the width of the dividing area 114 formed by the first region 1141 and the second region 1142. The width of b2 can be greater than 0 and less than or equal to 0.5 mm. Preferably, the width of b2 can be 0.15 mm.

[0071] In another alternative scheme, the first region 1141 and the second region 1142 can be symmetrically arranged about the splicing edge of the sensor photosensitive area 1123 and the light-distributing textured surface adjacent to the sensor photosensitive area 1123. Here, the splicing edge refers to the edge formed at the point where the sensor photosensitive area 1123 and the light-distributing textured surface adjacent to the sensor photosensitive area 1123 meet. In this scheme, the first region 1141 and the second region 1142 are symmetrically arranged about the splicing edge, thus achieving a better visual effect and further improving the appearance performance of the supplementary lighting.

[0072] Optionally, in the scheme shown in Figure 11, the width of both the first region 1141 and the second region 1142 can be 0.05 mm. In the scheme shown in Figure 13, the width of both the first region 1141 and the second region 1142 can be 0.075 mm.

[0073] Based on the fill light 100 disclosed in the embodiments of this application, the embodiments of this application also disclose an electronic device, which includes the fill light 100 described in any of the embodiments above.

[0074] As shown in Figures 15 and 16, the electronic device disclosed in this application may further include a housing 200, a circuit board 300, and a camera module 400. The housing 200 provides a mounting base for other components of the electronic device. The camera module 400 and the circuit board 300 are both mounted on the housing 200. The aforementioned supplementary light 100 can be located within the accommodating space of the housing 200. The housing 200 has a light-transmitting area 210, which can be a light-transmitting hole or a solid area that allows light to pass through. The light-emitting surface 111 of the light distribution element 110 can be arranged opposite to the light-transmitting area 210. The circuit board 300 can be the main board or a secondary board of the electronic device. The first light source 121 and the second light source 122 can both be mounted on the circuit board 300, which supplies power to the light source of the supplementary light 100 and controls the on and off of the light source. In addition, the spectral sensor 130 in the above scheme can also be electrically connected to the circuit board 300.

[0075] In the above solution, the camera module 400 can be a single camera capable of multi-focal length adjustment. Depending on the focal length, either the first light source 121 or the second light source 122 can be activated.

[0076] In another embodiment, the camera module 400 may include a first camera and a second camera, which are different cameras. When the first camera is in supplementary lighting mode, the first light source 121 is turned on, and the light spot formed by the first light source 121 through the first light distribution texture surface 1121 is used to supplement the lighting of the first camera. See light spot A1 in Figure 4 and light spot A3 in Figure 7. When the second camera is in supplementary lighting mode, the second light source 122 is turned on, and the light spot formed by the second light distribution texture surface 1122 through the second light source 122 is used to supplement the lighting of the second camera. See light spot A2 in Figure 4 and light spot A4 in Figure 7.

[0077] In the embodiments disclosed in this application, the fill light 100 can form a variety of different light spots, and the illuminance and viewing angle range of the various different light spots are different. Therefore, the fill light 100 in this application can meet the fill light requirements of cameras with different focal lengths in electronic devices, thereby improving the fill light performance of electronic devices and enabling electronic devices to have better shooting performance.

[0078] In another alternative, the first camera can be a wide-angle camera. Wide-angle cameras have a wide shooting range but a short shooting distance, therefore requiring a supplementary light 100 to project a large area of ​​low-illuminance light spot. The second camera can be a main camera. Main cameras have a moderate shooting range and distance, therefore requiring a supplementary light 100 to project a light spot with a moderate range and moderate illumination.

[0079] The viewing angle range generated by the first light-emitting light source 121 through the first light-distribution texture surface 1121 is greater than the viewing angle range generated by the second light-emitting light source 122 through the second light-distribution texture surface 1122. Since the viewing angle range of the light spot projected by the first light-emitting light source 121 through the first light-distribution texture surface 1121 is greater than that of the light spot projected by the second light-emitting light source 122 through the second light-distribution texture surface 1122, the illuminance of the light spot projected by the first light-emitting light source 121 through the first light-distribution texture surface 1121 is less than the illuminance of the light spot projected by the second light-distribution texture surface 122 through the second light-distribution texture surface 1122. Therefore, the illuminance of the light spot projected by the first light-emitting light source 121 through the first light-distribution texture surface 1121 is small, but the illumination range is large. Conversely, the illuminance of the light spot projected by the second light-emitting light source 122 through the second light-distribution texture surface 1122 is large, but the illumination range is small. Therefore, the light spot projected by the first light source 121 through the first light distribution texture surface 1121 can meet the lighting requirements of the wide-angle camera, while the light spot projected by the second light source 122 through the second light distribution texture surface 1122 can meet the lighting requirements of the main camera.

[0080] This solution can meet the lighting needs of both wide-angle and main cameras, thereby improving the shooting performance of electronic devices.

[0081] In one specific embodiment, when the fill light 100 needs to provide supplementary lighting for both the wide-angle camera and the main camera, the fill light 100 can adopt the structure shown in Figure 1. In this case, the first light-incident structure 11201 on the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122 is identical. The tooth width and tooth height of the annular teeth 11202a on the first light-distributing texture surface 1121 are the same as those on the second light-distributing texture surface 1122. The swing angle of the annular teeth 11202a on the first light-distributing texture surface 1121 is greater than that on the second light-distributing texture surface 1122. The specific dimensions of the fill light 100 can be obtained from the data in Table 1 above. As shown in Figure 4, Figure 4 is a light energy illuminance distribution diagram of the light spots projected by the first light source 121 and the second light source 122 under the same current drive on a projection plane at a distance of 1000mm. The size of the distribution diagram is 1006mm*1342mm (the diagonal length is the 80° angle range).

[0082] As shown in Figure 4, the light projected by the first light source 121 is modulated by the first light distribution texture surface 1121 to form a light spot A1. The A1 light spot has a large viewing angle, which can well fill the entire 1006mm*1342mm area (diagonal length of 80°), and the illuminance at the center exceeds 40 lux, which well matches the shooting needs of the wide-angle camera. The light projected by the second light source 122 is modulated by the second light distribution texture surface 1122 to form a light spot A2. The A2 light spot has a moderate viewing angle, which can well fill the entire 560mm*746mm area (diagonal length of 50°, black frame area), and the illuminance at the center exceeds 70 lux, which well matches the shooting needs of the main camera. Therefore, when the wide-angle camera is in the fill light state, turning on the first light source 121 can achieve good fill light; when the main camera is in the fill light state, turning on the second light source 122 can achieve good fill light.

[0083] In one design, the first camera can be a wide-angle camera, and the second camera can be a telephoto camera. The telephoto camera has a small shooting range and a long shooting distance, therefore a flash is needed to project a small area of ​​high-illuminance light spot. In this case, the specific structure of the fill light 100 can be as shown in Figure 5. The texture structure of the first light-distributing texture surface 1121 can be the same as the texture structure in the design of Figure 1. Therefore, when the wide-angle camera is in fill light mode, turning on the first light source 121 is sufficient to achieve good fill light. The second light-distributing texture surface 1122 needs to be redesigned, and its structure is shown in Figure 6. The specific dimensions can be obtained from the data in Table 2 above.

[0084] Figure 7 shows the light energy illuminance distribution of the light spots projected by the first light source 121 and the second light source 122 at a distance of 1000mm on a projection plane when both are driven by the same current. The size of the distribution diagram is 1006mm*1342mm (the diagonal length is the 80° angle range).

[0085] The light projected by the first light source 121 is modulated by the first light distribution texture surface 1121 to form a light spot A3. When the current of the first light source 121 is the same as that in the schemes of Figure 1 and Figure 5, the light spot A3 is the same as the light spot A1. The light spot A1 matches the shooting requirements of the wide-angle camera.

[0086] The light projected by the second light source 122 is modulated by the second light distribution texture surface 1122 to form an A4 light spot. The A4 light spot has a small illumination range and high center illuminance, which can well fill the entire 320mm*428mm area (diagonal length of 30° angular range, black frame area), and the illuminance at the center reaches 119 lux, which basically matches the shooting requirements of a telephoto camera. Therefore, when the wide-angle camera is in the illumination state, turning on the first light source 121 is sufficient to achieve good illumination. When the telephoto camera is in the illumination state, turning on the second light source 122 is sufficient to achieve good illumination.

[0087] In the two schemes shown in Figures 1 and 5, besides the difference in the structure of the second light-distributing texture surface 1122, the distance between the second light-emitting source 122 and the second light-distributing texture surface 1122 can also be different. Since the structure of the first light-distributing texture surface 1121 is the same in both schemes of Figures 1 and 5, g1 and g3 can be the same. In both schemes of Figures 1 and 5, g4 needs to be greater than g2, and g2 needs to be greater than g1 and g3.

[0088] In another alternative embodiment, the camera module 400 may further include a third camera. When the third camera is in supplementary lighting mode, the first light source 121 and the second light source 122 can be turned on simultaneously, and the viewing angle range generated by the first light source 121 through the first light distribution texture surface 1121 overlaps with the viewing angle range generated by the second light source 122 through the second light distribution texture surface 1122. That is, the light spot formed by the first light source 121 through the first light distribution texture surface 1121 and the light spot formed by the second light source 122 through the second light distribution texture surface 1122 are superimposed to form a new light spot. This light spot may have the viewing angle range of the light spot formed by the first light source 121 through the first light distribution texture surface 1121 and the brightness of the light spot formed by the second light source 122 through the second light distribution texture surface 1122.

[0089] For example, when the first light source 121 and the second light source 122 can be turned on simultaneously and have the same current, the light spot formed by the supplementary light lamp 100 has a larger supplementary lighting range and stronger light intensity. Optionally, the current of both the first light source 121 and the second light source 122 can be 500mA.

[0090] In one specific embodiment, the structure of the fill light 100 can be as shown in Figure 5. In this case, when the first light source 121 and the second light source 122 operate simultaneously, and the driving current of both light sources 121 and 122 is less than the current when they are lit individually, the viewing angle and illuminance of the light spots formed by the simultaneous illumination of the first and second light sources 121 are both less than the viewing angle and illuminance of the light spots formed when the first and second light sources 121 are lit individually. Therefore, the illuminance and viewing angle of the superimposed light spot are both within the range of the light spots formed when they are lit individually, thus it can be used for fill light for the main camera.

[0091] Specifically, when the supplementary light 100 is in its first operating state, the first light source 121 is turned on, and the second light source 122 is turned off. The first light source 121 projects a first light spot through the first light distribution texture surface 1121. When the supplementary light 100 is in its second operating state, the second light source 122 is turned on, and the first light source 121 is turned off. The second light source 122 projects a second light spot through the second light distribution texture surface 1122. When the supplementary light 100 is in its third operating state, as shown in Figure 8, the first light source 121 and the second light source 122 are turned on simultaneously. The light spot projected by the first light source 121 through the first light distribution texture surface 1121 and the light spot projected by the second light source 122 through the second light distribution texture surface 1122 are superimposed to form a third light spot. The current of the first light source 121 in the third operating state is less than the current in the first operating state; the current of the second light source 122 in the third operating state is less than the current in the second operating state. The illuminance of the third spot is greater than that of the first spot, but less than that of the second spot; the viewing angle of the third spot is smaller than that of the first spot, but larger than that of the second spot.

[0092] In one specific scheme, as shown in Figure 5, when the first light source 121 and the second light source 122 are lit, they can be combined to create a light spot that meets the fill light requirements of the main camera, satisfying a center illuminance greater than 70 lux. As shown in Figure 8, after superposition, an A5 light spot is formed, which fills a 560mm*746mm (diagonal length of 50°, black frame area) fill light region. Therefore, the A5 light spot meets the fill light requirements of the main camera.

[0093] This application discloses a supplementary lighting strategy for a supplementary light lamp 100, as described in Table 3 below.
