DETAILED DESCRIPTION

[0031] ​​​​With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly described. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0032] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally means that the front and rear associated objects are in a "or" relationship.

[0033] The light supplement lamp and electronic device provided by the embodiments of the present application will be described in detail below in combination with the drawings, through specific embodiments and application scenarios.

[0034] Please refer to Figures 1 to 14 The embodiments of the present application disclose a light supplement lamp 100 applied to an electronic device, and the disclosed light supplement lamp 100 comprises a light distribution member 110, a first light emitting source 121 and a second light emitting source 122.

[0035] The light distribution member 110 has an opposite light emitting surface 111 and a light entering surface 112, and the light entering surface 112 comprises a first light distribution textured surface 1121 and a second light distribution textured surface 1122 arranged side by side. The first light emitting source 121 is arranged opposite to the first light distribution textured surface 1121, and the second light emitting source 122 is arranged opposite to the second light distribution textured surface 1122. The light emitted by the first light emitting source 121 and the second light emitting source 122 is emitted from the light emitting surface 111 after passing through the corresponding light distribution textured surface. The material of the light distribution member 110 can be PC (Polycarbonate, polycarbonate), and of course can also be other materials, which is not limited herein.

[0036] In the working process of the light supplementing lamp 100, when the first light emitting source 121 is lighted, the light emitted by the first light emitting source 121 is lighted through the first light distribution texture surface 1121 and then emitted from the light emitting surface 111. When the second light emitting source 122 is lighted, the light emitted by the second light emitting source 122 is lighted through the second light distribution texture surface 1122 and then emitted from the light emitting surface 111. The light emitted by the first light emitting source 121 and the light emitted by the second light emitting source 122 can be emitted from 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, the first light emitting area is arranged opposite to the first light distribution texture surface 1121, and the light emitted by the first light emitting source 121 is lighted through the first light distribution texture surface 1121 and then emitted from the first light emitting area. The second light emitting area is arranged opposite to the second light distribution texture surface 1122, and the light emitted by the second light emitting source 122 is lighted through the second light distribution texture surface 1122 and then emitted from the second light emitting area.

[0037] In the embodiments disclosed in the present application, the texture structures on the first light distribution texture surface 1121 and the second light distribution texture surface 1122 are different. At this time, because the texture structures of the two light distribution textures are different from each other, the illumination and the visual angle range of the light spots projected by the first light emitting source 121 and the second light emitting source 122 through the corresponding light distribution texture surfaces are also different. The visual angle range of the light spot refers to the range of the light spot that can be illuminated by the projected light spot, and the illumination of the light spot refers to the brightness of the light spot. For example, when the first light distribution texture surface 1121 shrinks the opening angle of the light emitted by the first light emitting source 121 to a small angle, the radiation angle of the light emitted by the first light emitting source 121 after passing through the first light distribution texture surface 1121 is large, so the visual angle range of the projected light spot is large, and the illumination of the light spot is small. Because the visual angle range of the light spot is large, the brightness of the light spot is low. When the second light distribution texture surface 1122 shrinks the opening angle of the light emitted by the second light emitting source 122 to a large angle, the radiation angle of the light emitted by the second light emitting source 122 after passing through the second light distribution texture surface 1122 is small, so the visual angle range of the projected light spot is small, and the light is concentrated, so the illumination of the light spot is large. At this time, the visual angle range of the light spot is small, and the brightness of the light spot is large. Because the visual angle range of the light spot transmitted by the first light emitting source 121 through the first light distribution texture surface 1121 is large, the range that can be illuminated is wide, so the light spot transmitted by the first light emitting source 121 through the first light distribution texture surface 1121 can supplement the light for the camera with a large focal length in the shooting field of view, for example, a wide-angle camera. The visual angle range of the light spot transmitted by the second light emitting source 122 through the second light distribution texture surface 1122 is small, but the brightness is high, so the distance of the illumination is far. Therefore, the light spot transmitted by the second light emitting source 122 through the second light distribution texture surface 1122 can supplement the light for the camera with a small focal length in the shooting field of view, for example, a long-focus camera.

[0038] Of course, the embodiments disclosed in the present application are not limited to the different texture structures on the first light distribution textured surface 1121 and the second light distribution textured surface 1122. The distance between the first light emitting light source 121 and the second light emitting light source 122 and the corresponding light distribution textured surface can also be different. For example, in the case of the same structure of the first light distribution textured surface 1121 and the second light distribution textured surface 1122, the distance between the first light distribution textured surface 1121 and the first light emitting light source 121 is smaller than the distance between the second light distribution textured surface 1122 and the second light emitting light source 122. The distance between the first light distribution textured surface 1121 and the first light emitting light source 121 is closer, so the viewing angle range of the light spot transmitted by the first light emitting light source 121 through the first light distribution textured surface 1121 is larger. The distance between the second light distribution textured surface 1122 and the second light emitting light source 122 is farther, so the viewing angle range of the light spot transmitted by the second light emitting light source 122 through the second light distribution textured surface 1122 is smaller.

[0039] In another scheme, the texture structures on the first light distribution textured surface 1121 and the second light distribution textured surface 1122 are different, and the distances between the first light emitting light source 121 and the second light emitting light source 122 and the corresponding light distribution textured surface are also different. At this time, the difference between the light spots can be increased by the different distances and texture structures.

[0040] In the embodiments disclosed in the present application, the light supplement lamp 100 can form a plurality of different light spots, and the illuminance and viewing angle range of the plurality of different light spots are different. Therefore, the light supplement lamp 100 in the present application can meet the light supplement demand of the cameras of different focal lengths in the electronic device, thereby improving the light supplement performance of the electronic device, and further making the electronic device have good shooting performance.

[0041] In addition, the light supplement lamp 100 disclosed in the present application can realize light supplement of multiple focal lengths without increasing the number of light supplement lamps 100 and the number of light transmission regions 210 on the electronic device. Therefore, in terms of appearance, the electronic device still has only one light supplement lamp 100, thereby improving the appearance performance of the electronic device. At the same time, since the number of openings of the electronic device is small, the waterproof and dustproof performance of the electronic device is also improved.

[0042] In addition, the light supplement lamp 100 disclosed in the present application can realize different light supplement light spots through the different texture structures of the light distribution textured surface and / or the different distances between the light distribution textured surface and the corresponding light emitting light source. Therefore, the optical structure is simple and the cost is low.

[0043] In the above scheme, the texture structure of the first light distribution texture surface 1121 and the second light distribution texture surface 1122 can be an arc convex surface, or a plurality of tooth-shaped structures arranged in sequence and continuously. Of course, the texture structure on the first light distribution texture surface 1121 and the second light distribution texture surface 1122 can also be other structures, which are not limited herein. The first light distribution texture surface 1121 and the second light distribution texture surface 1122 described above can both be arc convex surfaces, at this time the radii of the two arc convex surfaces are different, so that the radiation angles of the two light distribution texture surfaces to the light are different. Alternatively, the first light distribution texture surface 1121 and the second light distribution texture surface 1122 can both include a plurality of tooth-shaped structures, at this time at least one of the tooth width, tooth height and swing angle of the tooth-shaped structure on the first light distribution texture surface 1121 and the tooth width, tooth height and swing angle of the tooth-shaped structure on the second light distribution texture surface 1122 is different, so that the radiation angles of the two light distribution texture surfaces to the light are different.

[0044] In another optional embodiment, the first light distribution texture surface 1121 can be rotationally symmetrical about the central optical axis of the first light-emitting light source 121. The central optical axis of the first light-emitting light source 121 herein refers to the optical axis of the central position of the first light-emitting light source 121 or the physical center line of the first light-emitting light source 121. The central optical axis of the first light-emitting light source 121 is as shown by O1 in Figure 1 and Figure 5 The second light distribution texture surface 1122 can be rotationally symmetrical about the central optical axis of the second light-emitting light source 122. The central optical axis of the second light-emitting light source 122 herein refers to the optical axis of the central position of the second light-emitting light source 122 or the physical center line of the second light-emitting light source 122. The central optical axis of the second light-emitting light source 122 is as shown by O2 in Figure 1 and Figure 5 .

[0045] The first light distribution texture surface 1121 and the second light distribution texture surface 1122 can both include a first light-in structure 11201 and a second light-in structure 11202, the second light-in structure 11202 can be arranged around the first light-in structure 11201, the first light-in structure 11201 is an arc convex surface, and the second light-in structure 11202 can include a plurality of annular teeth 11202a, the plurality of annular teeth 11202a are arranged continuously in a direction away from the first light-in structure 11201. Here, the plurality of annular teeth 11202a arranged continuously in a direction away from the first light-in structure 11201 refers to the direction from the center to the edge of the first light distribution texture surface 1121 or the second light distribution texture surface 1122.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] In another alternative scheme, at least one of the tooth width, tooth height, and swing angle of the annular teeth 11202a on the first light distribution texture surface 1121 and the second light distribution texture surface 1122 is different. Here, tooth height refers to the distance between the root and the tip of each annular tooth 11202a. Figure 2 h1 in the figure represents the tooth height of the annular tooth 11202a on the first light distribution texture surface 1121. Figure 3 h2 in the figure represents the tooth height of the annular tooth 11202a on the second light distribution texture surface 1122. The tooth width refers to the width of each annular tooth 11202a, which is the distance between the tooth roots or tooth bases on opposite sides of each annular tooth 11202a.Figure 2 w1 is the tooth width of the annular teeth 11202a on the first light distribution textured surface 1121, Figure 3 w2 is the tooth width of the annular teeth 11202a on the second light distribution textured surface 1122. The tilt angle refers to the tilt angle of the annular teeth 11202a, which can be represented by one of the side surfaces of the annular teeth 11202a. Alternatively, the tilt angle of each annular tooth 11202a can be represented by the tilt angle of the line connecting the midpoint between the two side tooth roots of each annular tooth 11202a and the tooth top. As shown in FIG. 11A, a1 is the line connecting the midpoint between the two side tooth roots of the annular teeth 11202a and the tooth top on the first light distribution textured surface 1121. As shown in FIG. 11B, a2 is the line connecting the midpoint between the two side tooth roots of the annular teeth 11202a and the tooth top on the second light distribution textured surface 1122. Figure 2 Figure 3 In one embodiment, the light incidence surface 112 can be used as the reference surface, and the tilt angle of a1 relative to the light incidence surface 112 is the tilt angle of the annular teeth 11202a on the first light distribution textured surface 1121. Similarly, the tilt angle of a2 relative to the light incidence surface 112 is the tilt angle of the annular teeth 11202a on the second light distribution textured surface 1122. Alternatively, 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 teeth 11202a on the first light distribution textured 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 teeth 11202a on the second light distribution textured surface 1122. The tilt angle in this application can be represented by the tilt angle of a1 and a2 relative to the light incidence surface 112.

[0051] In one embodiment, the first light incidence structure 11201 on the first light distribution textured surface 1121 and the second light distribution textured surface 1122 is the same, which means that the surface type and size of the first light incidence structure 11201 on the two light distribution textured surfaces are the same. The tooth width and height of the annular teeth 11202a on the first light distribution textured surface 1121 are the same as those of the annular teeth 11202a on the second light distribution textured surface 1122. The tilt angle of the annular teeth 11202a on the first light distribution textured surface 1121 is greater than that of the annular teeth 11202a on the second light distribution textured surface 1122. In this embodiment, the tilt angles of the annular teeth 11202a on the first light distribution textured surface 1121 and the second light distribution textured surface 1122 are adjusted to achieve different illuminance and viewing angle ranges of the light spot. This embodiment has a simple structure and is easy to manufacture.

[0052] ​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 1122 are only different in the swing angle. That is, the tooth height, tooth width and swing angle of all the annular teeth 11202a on the first light distribution texture surface 1121 are the same. The tooth height, tooth width and swing angle of all the annular teeth 11202a on the second light distribution texture surface 1122 are the same.

[0053] In the scheme as 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 1122 are different. The tooth height, tooth width and swing angle of all the annular teeth 11202a on the first light distribution texture surface 1121 are the same. The tooth height, tooth width and swing angle of all the annular teeth 11202a on the second light distribution texture surface 1122 are the same. In a specific scheme, Figure 1 The specific data of the light supplement lamp 100 as shown in Table 1 are as follows.

[0054] Table 1

[0055]

[0056] Here, the distance between the light distribution texture and the corresponding light source can be understood as the distance between the highest point of the first light entry 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 on the first light distribution texture surface 1121 and the second light distribution surface can be within the range of plus or minus 0.05 mm. The swing angle can be within the range of plus or minus 15 degrees. The distance between the light distribution texture and the corresponding light source can be within the range of plus or minus 0.2 mm. Only one specific light distribution texture structure is described herein, and of course, the texture on the first light distribution texture surface 1121 and the second light distribution texture surface 1122 can also have other size values, which are not limited herein.

[0057] In another scheme, as shown in Figure 5As shown, the diameter of the contour of the orthographic projection of the first light entry structure 11201 on the first light distribution texture surface 1121 is smaller than the diameter of the contour of the orthographic projection of the first light entry structure 11201 on the second light distribution texture surface 1122. In the radial direction of the second light distribution texture surface 1122, the distance between the tooth top of the annular tooth 11202a of the second light distribution texture surface 1122 and the light exit surface 111 gradually increases. Here, the radial direction of the second light distribution texture surface 1122 refers to the direction in which the center of the second light distribution texture surface 1122 extends to its edge.

[0058] In this scheme, the diameter of the contour of the orthographic projection of the arc-shaped convex surface on the first light distribution texture surface 1121 is smaller than the diameter of the contour of the orthographic projection of the arc-shaped convex surface on the second light distribution texture surface 1122, so that the light entry aperture of the arc-shaped convex surface on the second light distribution texture surface 1122 is larger, so that the arc-shaped convex surface on the second light distribution texture surface 1122 can collimate more light, thereby further improving the center brightness of the light spot transmitted by the second light distribution texture surface 1122, and further improving the illuminance of the light spot. In addition, the light exit surface 111 serves as a reference surface, so the distance between the tooth top of the annular tooth 11202a on the second light distribution texture surface 1122 and the light exit surface 111 gradually increases, which means that the tooth top of the outer annular tooth 11202a protrudes from the tooth top of the inner annular tooth 11202a, thereby avoiding the outer annular tooth 11202a being blocked by the inner annular tooth 11202a, thereby further improving the utilization rate of light and further improving the brightness of the transmitted light spot. Therefore, through the above structure, the second light distribution texture surface 1122 can transmit a light spot with a smaller light supplement range and extremely high center illuminance, thereby meeting the light supplement requirements of the long-focus camera.

[0059] 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 contour of the orthographic projection of the arc-shaped convex surface. Figure 1 The arc-shaped convex surface of the first light distribution texture surface 1121 and the arc-shaped convex surface of the second light distribution texture surface 1122 in Figure 6 The width of the arc-shaped convex surface of the first light distribution texture surface 1121 in

[0060] In one scheme, the tooth height, tooth width and swing angle of all annular teeth 11202a on the second light distribution texture surface 1122 can be the same. At this time, the position of each annular tooth 11202a in the direction of the central optical axis of the second light emitting source 122 can be adjusted, so that the distance between the tooth top of the annular tooth 11202a of the second light distribution texture surface 1122 and the light exit surface 111 gradually increases.

[0061] In another alternative embodiment, the tooth width and tooth height of each annular tooth 11202a on the second light distribution texture surface 1122 are both larger than the tooth width and tooth height of each annular tooth 11202a on the first light distribution texture surface 1121. In this scheme, the tooth width and tooth height of each annular tooth 11202a on the second light distribution texture surface 1122 are both larger in size, thus the light shrinking performance is further improved, which is beneficial to further reduce the light spot range and improve the light spot brightness.

[0062] Optionally, as shown in Figure 6 the tooth width and tooth height of each annular tooth 11202a on the first light distribution texture surface 1121 can be about 0.15mm, while the tooth width and tooth height of each annular tooth 11202a on the second light distribution texture surface 1122 can be between 0.3mm and 0.4mm, thus the tooth width and tooth height of each annular tooth 11202a on the second light distribution texture surface 1122 can be twice the size of the tooth width and tooth height of each annular tooth 11202a on the first light distribution texture surface 1121.

[0063] In another alternative scheme, the tooth width, tooth height and swing angle between 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 each annular tooth 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 light spot range and improve the light spot brightness, and achieve the ultimate light spot effect of ultra-high brightness.

[0064] In a specific scheme, Figure 6 the specific data of the second light distribution texture surface 1122 is shown in Table 2 below.

[0065] Table 2

[0066]

[0067] The O point is the origin of the coordinate system, which can be the highest point of the arc-shaped convex surface of the second light distribution texture surface 1122, or can be understood as the intersection of the central optical axis of the second light-emitting light source 122 and the arc-shaped convex surface. The A, C, E, G, I, K, and M are the coordinates of the tooth root or the tooth bottom of each annular tooth 11202a of the second light distribution texture surface 1122, and the B, D, F, H, J, L, and N are the coordinates of the tooth top of each annular tooth 11202a of the second light distribution texture surface 1122. Through the coordinates of the tooth top and the tooth root of each annular tooth 11202a, a continuous tooth profile line can be obtained, and the tooth profile line rotates one circle around the central optical axis of the second light-emitting light source 122, so that the second light-incident structure 11202 in the application can be obtained. The above-mentioned coordinates can be between 0.05mm.

[0068] In another optional scheme, the light-incident surface 112 can further include a sensor photosensitive area 1123, which can be located between the first light distribution texture surface 1121 and the second light distribution texture surface 1122. The light supplement lamp 100 can further include a spectrum sensor 130, which is arranged opposite to the sensor photosensitive area 1123.

[0069] In a specific operation process, the external environment light enters the light distribution member 110 through the light-emitting surface 111, and then is received by the spectrum sensor 130 after passing through the sensor photosensitive area 1123. The spectrum sensor is responsible for accepting the external environment light, and the spectrum sensor 130 is responsible for accepting the external environment light, sensing the external spectrum information, so as to improve the color performance of the photo.

[0070] This scheme can further improve the shooting performance of the electronic device. In addition, because the texture structures on the first light distribution texture surface 1121 and the second light distribution texture surface 1122 are different, the seams at the boundaries of the texture areas cannot be symmetrical left and right, which has no effect on the optical performance, but causes strong light reflection or burr feeling in the visual effect in the seam area, thereby reducing the appearance performance of the light supplement lamp 100. The sensor photosensitive area 1123 is located between the first light distribution texture surface 1121 and the second light distribution texture surface 1122, thereby spacing the first light distribution texture surface 1121 and the second light distribution texture surface 1122. In the case that no texture is arranged on the sensor photosensitive area 1123, that is, the sensor photosensitive area 1123 is a plane, a plane area is arranged at the joint area of different texture areas, so that the strong light reflection or burr feeling in the visual effect can be solved, thereby improving the appearance performance of the light supplement lamp 100.

[0071] In the above scheme, the specific structure and working principle of the spectrum sensor 130 are not limited herein.

[0072] In the embodiments disclosed in the present application, the first light distribution texture surface 1121, the second light distribution texture surface 1122 and the sensor photosensitive region 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, the first light emitting area is arranged opposite to the first light distribution texture surface 1121, the second light emitting area is arranged opposite to the second light distribution texture surface 1122, and the third light emitting area is arranged opposite to the sensor photosensitive region 1123.

[0073] However, in order to make more external light enter the sensor photosensitive region 1123 of the spectrum sensor 130, a light control texture 1123a is usually arranged, for example, as shown in Figure 9 The light control texture 1123a with a tooth-shaped structure is arranged on the sensor photosensitive region 1123, so as to realize the light distribution requirement of the spectrum sensor 130. At this time, the sensor photosensitive region 1123 is no longer a flat structure, as shown in Figure 10 The light control texture 1123a on the sensor photosensitive region 1123 and the joint between the texture area boundaries of the first light distribution texture surface 1121 and the second light distribution texture surface 1122 are not symmetrical, so that the joint area will cause strong light reflection or burr visual effect in visual perception, thereby reducing the appearance performance of the light supplement lamp 100.

[0074] Based on this, in another optional scheme, as shown in Figure 11 and Figure 13 The joint between the sensor photosensitive region 1123 and the adjacent light distribution texture surface is provided with a separation area 114, which is used to separate the light control texture 1123a on the sensor photosensitive region 1123 from the texture structure on the adjacent light distribution texture surface. In this scheme, a narrow area is arranged at the joint of different area textures, which can separate the two joint textures, so as to solve the strong light reflection or burr feeling in visual perception, thereby improving the appearance performance of the light supplement lamp 100.

[0075] In the above scheme, a rectangular plane can be arranged between the sensor light receiving area 1123 and the joint of the light distribution texture surface adjacent thereto. It can also be understood that, when the first light distribution texture surface 1121, the second light distribution texture surface 1122 and the sensor light receiving area 1123 are arranged, the first light distribution texture surface 1121 is spaced apart from the sensor light receiving area 1123 by a certain distance to form a plane. The second light distribution texture surface 1122 is spaced apart from the sensor light receiving area 1123 by a certain distance to form a plane. Alternatively, the edge of the sensor light receiving area 1123 is provided with a first area 1141, and the edge of the light distribution texture surface adjacent to the sensor light receiving area 1123 is provided with a second area 1142, and the first area 1141 and the second area 1142 are jointed to form the separation area 114. It can be understood here that the first area 1141 is a reserved area without texture at the edge of the sensor light receiving area 1123. Similarly, the second area 1142 is a reserved area without texture at the edge of the first light distribution texture surface 1121 or the second light distribution texture surface 1122. As shown in Figure 11 and Figure 12 The first area 1141 and the second area 1142 are planar areas as shown in b1. The width b1 is the width of the separation area 114 formed by the first area 1141 and the second area 1142. The width b1 can be greater than 0 and less than or equal to 0.5 mm. Preferably, the width b1 can be 0.1 mm.

[0076] Alternatively, the first area 1141 is a misted area at the edge of the sensor light receiving area 1123, that is, the entire area of the sensor light receiving area 1123 is provided with the light control texture 1123a, but a certain width area at the edge of the sensor light receiving area 1123 is misted to reduce its light transmittance, thereby reducing the strong reflection or burr feeling in vision. Similarly, the second area 1142 is a misted area at the edge of the first light distribution texture surface 1121 or the second light distribution texture surface 1122. As shown in Figure 13 and Figure 14 The first area 1141 and the second area 1142 are misted areas as shown in b2. The misting effect can be formed by laser, etching and other processes. The width b2 is the width of the separation area 114 formed by the first area 1141 and the second area 1142. The width b2 can be greater than 0 and less than or equal to 0.5 mm. Preferably, the width b2 can be 0.15 mm.

[0077] In another alternative, the first region 1141 and the second region 1142 can be symmetrically arranged about the joint line of the sensor light-sensing region 1123 and the light distribution texture surface adjacent to the sensor light-sensing region 1123. The joint line here refers to the line formed by the position where the sensor light-sensing region 1123 and the light distribution texture surface adjacent to the sensor light-sensing region 1123 are in contact. In this scheme, the first region 1141 and the second region 1142 are symmetrically arranged about the joint line, thereby having better visual effect, and thus further improving the appearance performance of the light compensation.

[0078] Optionally, in the above-mentioned scheme, the width of the first region 1141 and the second region 1142 can be 0.05 mm. Figure 11 In the scheme shown in the above-mentioned scheme, the width of the first region 1141 and the second region 1142 can be 0.075 mm. Figure 13

[0079] Based on the light compensation lamp 100 disclosed in the embodiments of the present application, the embodiments of the present application further disclose an electronic device, and the disclosed electronic device comprises the light compensation lamp 100 described in any of the above-mentioned embodiments.

[0080] As shown in the above-mentioned scheme, the first region 1141 and the second region 1142 can be symmetrically arranged about the joint line of the sensor light-sensing region 1123 and the light distribution texture surface adjacent to the sensor light-sensing region 1123. Figure 15 and Figure 16 As shown in the above-mentioned scheme, the electronic device disclosed in the present application can further comprise a housing 200, a circuit board 300 and a camera module 400, the housing 200 provides a mounting basis for other constituent components of the electronic device, the camera module 400 and the circuit board 300 are both arranged on the housing 200, and the above-mentioned light compensation lamp 100 can be located in the accommodation space of the housing 200. The housing 200 is provided with a light-transmitting region 210, which can be a light-transmitting hole or a solid region that can transmit light. The light emitting surface 111 of the light distribution piece 110 can be arranged opposite to the light-transmitting region 210. The circuit board 300 here can be the main board of the electronic device, or the auxiliary board of the electronic device. The first light emitting source 121 and the second light emitting source 122 can both be arranged on the circuit board 300, and the circuit board 300 supplies power to the light emitting sources of the light compensation lamp 100 and controls the opening and closing of the light emitting sources. In addition, the spectrum sensor 130 in the above-mentioned scheme can also be electrically connected with the circuit board 300.

[0081] In the above-mentioned scheme, the camera module 400 can be one camera, which can adjust the focal length in multiple focal segments. At this time, the first light emitting source 121 or the second light emitting source 122 can be selected to be turned on according to different focal segments.

[0082] ​In another solution, the camera module 400 can include a first camera and a second camera, the first camera and the second camera being different cameras. When the first camera is in the light supplementing state, the first light emitting source 121 is turned on, and at this time, the light spot formed by the first light distribution texture surface 1121 is used to supplement light for the first camera. As shown in FIG. 10A, the light spot formed by the first light distribution texture surface 1121 is the A1 light spot in FIG. 10B, and the A3 light spot in FIG. 10C. Figure 4 When the second camera is in the light supplementing state, the second light emitting source 122 is turned on, and at this time, the light spot formed by the second light distribution texture surface 1122 is used to supplement light for the second camera. As shown in FIG. 10A, the light spot formed by the second light distribution texture surface 1122 is the A2 light spot in FIG. 10B, and the A4 light spot in FIG. 10C. Figure 7 Figure 4 Figure 7 In the embodiments disclosed in the present application, the light supplementing lamp 100 can form a plurality of different light spots, and the illuminance and the viewing angle range of the plurality of different light spots are different, so that the light supplementing lamp 100 in the present application can meet the light supplementing requirements of the cameras with different focal lengths in the electronic device, thereby improving the light supplementing performance of the electronic device, and further improving the shooting performance of the electronic device.

[0083] In another optional solution, the first camera can be a wide-angle camera, and the wide-angle camera has a wide shooting range but a short shooting distance, so that the light supplementing lamp 100 needs to project a light spot with a large range and low illuminance. The second camera can be a main camera, and the main camera has a moderate shooting range and a moderate shooting distance, so that the light supplementing lamp 100 needs to project a light spot with a moderate range and moderate illuminance.

[0084] The viewing angle range of the light spot projected by the first light emitting source 121 through the first light distribution texture surface 1121 is greater than the viewing angle range of the light spot projected by the second light emitting source 122 through the second light distribution texture surface 1122. At this time, since the viewing angle range of the light spot projected by the first light emitting source 121 through the first light distribution texture surface 1121 is greater than the viewing angle range of the light spot projected by the second light emitting source 122 through the second light distribution texture surface 1122, the illuminance of the light spot projected by the first light emitting source 121 through the first light distribution texture surface 1121 is less than the illuminance of the light spot projected by the second light emitting source 122 through the second light distribution texture surface 1122. Therefore, the light spot projected by the first light emitting source 121 through the first light distribution texture surface 1121 has small illuminance but a large irradiation range. The light spot projected by the second light emitting source 122 through the second light distribution texture surface 1122 has large illuminance but a small irradiation range. Therefore, the light spot projected by the first light emitting source 121 through the first light distribution texture surface 1121 can meet the light supplementing requirements of the wide-angle camera, and the light spot projected by the second light emitting source 122 through the second light distribution texture surface 1122 can meet the light supplementing requirements of the main camera.

[0085]

[0086] ​​​This solution can meet the lighting needs of both wide-angle and main cameras, thereby improving the shooting performance of electronic devices.

[0087] In one specific solution, 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 employ methods such as... Figure 1 The structure shown is as follows. At this time, the first light-incident structure 11201 on the first light-distributing texture surface 1121 and the second light-distributing texture surface 1122 is 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. The specific dimensions of the supplementary light 100 can be obtained from the data in Table 1 above. For example... Figure 4 As shown, Figure 4 The first light source 121 and the second light source 122, driven by the same current, are respectively projected by light spots on a projection plane at a distance of 1000mm. The size of the distribution map is 1006mm*1342mm (the diagonal length is the 80° angle range).

[0088] like Figure 4 As shown, 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° angle range), 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° angle range, 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.

[0089] 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, high-illuminance spot of light. In this case, the specific structure of the fill light 100 can be as follows: Figure 5 As shown, the texture structure of the first light distribution texture surface 1121 can be compared with... Figure 1The texture structure in the scheme is the same, so when the wide-angle camera is in the state of light compensation, the first light source 121 is turned on to complete good light compensation. The second light distribution texture surface 1122 needs to be redesigned, and its structure is as shown in Figure 6 The specific size data can use the data in Table 2 above.

[0090] As Figure 7 The first light source 121 and the second light source 122 are driven by the same current, and the light energy illuminance distribution diagram of the light spot projected on the projection plane at a distance of 1000mm is shown in the figure. The size of the distribution diagram is 1006mm*1342mm (the diagonal length is 80° of the angle range).

[0091] The first light source 121 projects light rays, which are modulated by the first light distribution texture surface 1121 to form an A3 light spot. The first light source 121 is in Figure 1 And Figure 5 In the case of the same current in the scheme, the A3 light spot is the same as the A1 light spot, and the A1 light spot matches the shooting requirements of the wide-angle camera.

[0092] The second light source 122 projects light rays, which are modulated by the second light distribution texture surface 1122 to form an A4 light spot. The A4 light spot has a small light compensation range and high central illuminance, which can well fill the entire 320mm*428mm (the diagonal length is 30° of the angle range, and the black frame area) area, and the central illuminance reaches 119lux, basically matching the shooting requirements of the long-focus camera. Therefore, when the wide-angle camera is in the state of light compensation, the first light source 121 is turned on to complete good light compensation. When the long-focus camera is in the state of light compensation, the second light source 122 is turned on to complete good light compensation.

[0093] In the above Figure 1 And Figure 5 Two schemes, except that the structure of the second light distribution texture surface 1122 is different, the distance between the second light source 122 and the second light distribution texture surface 1122 can also be different. Because Figure 1 And Figure 5 The structure of the first light distribution texture surface 1121 in the two schemes is the same, so g1 and g3 can be the same. Figure 1 And Figure 5 In the two schemes, g4 needs to be greater than g2, and g2 is greater than g1 and g3.

[0094] In another alternative, the camera module 400 can further include a third camera. When the third camera is in a light supplementing state, the first light emitting source 121 and the second light emitting source 122 can be turned on simultaneously, and the view angle range formed by the first light emitting source 121 through the first light distribution texture surface 1121 can overlap with the view angle range formed by the second light emitting source 122 through the second light distribution texture surface 1122. That is, the light spot formed by the first light emitting source 121 through the first light distribution texture surface 1121 and the light spot formed by the second light emitting source 122 through the second light distribution texture surface 1122 are superimposed to form a new light spot. The new light spot can have the view angle range of the light spot formed by the first light emitting source 121 through the first light distribution texture surface 1121 and the brightness of the light spot formed by the second light emitting source 122 through the second light distribution texture surface 1122.

[0095] For example, in the case where the first light emitting source 121 and the second light emitting source 122 can be turned on simultaneously and the currents are the same, the light spot formed by the light supplementing lamp 100 has a larger light supplementing range and a stronger light intensity. Alternatively, the currents of the first light emitting source 121 and the second light emitting source 122 can each be 500 mA.

[0096] In a specific scheme, the specific structure of the light supplementing lamp 100 can be as shown in Figure 5 At this time, when the first light emitting source 121 and the second light emitting source 122 work simultaneously, and the driving currents of the first light emitting source 121 and the second light emitting source 122 are each less than the current when the first light emitting source 121 and the second light emitting source 122 work alone. At this time, the view angle range and the illuminance of the light spot formed by the first light emitting source 121 and the second light emitting source 122 when they work simultaneously are each less than the view angle range and the illuminance of the light spot formed by the first light emitting source 121 and the second light emitting source 122 when they work alone. Therefore, the illuminance and the view angle range of the light spot formed by the superposition are each between the illuminance and the view angle range of the light spot formed by the first light emitting source 121 and the second light emitting source 122 when they work alone, and thus the light supplementing lamp 100 can be used for light supplementing of a main camera.

[0097] Specifically, when the light supplementing lamp 100 is in the first working state, the first light emitting source 121 is turned on and the second light emitting source 122 is turned off, and the first light emitting source 121 projects to form a first light spot through the first light distribution texture surface 1121; when the light supplementing lamp 100 is in the second working state, the second light emitting source 122 is turned on and the first light emitting source 121 is turned off, and the second light emitting source 122 projects to form a second light spot through the second light distribution texture surface 1122; when the light supplementing lamp 100 is in the third working state, as shown in Figure 8As shown, the first light emitting source 121 and the second light emitting source 122 are turned on at the same time, and the light spot projected by the first light emitting source 121 through the first light distribution texture surface 1121 is superimposed with the light spot projected by the second light emitting source 122 through the second light distribution texture surface 1122 to form a third light spot. The current of the first light emitting source 121 in the third working state is less than the current of the first light emitting source 121 in the first working state; the current of the second light emitting source 122 in the third working state is less than the current of the second light emitting source 122 in the second working state. The illumination of the third light spot is greater than the illumination of the first light spot and less than the illumination of the second light spot; the viewing angle range of the third light spot is less than the viewing angle range of the first light spot and greater than the illumination range of the second light spot.

[0098] In a specific solution, as shown in FIG. 6, when the first light emitting source 121 and the second light emitting source 122 are turned on, a light spot meeting the light supplementing requirement of the main camera can be fused out, and the central illumination is greater than 70 lux. Figure 5 As shown in FIG. 6, when the first light emitting source 121 and the second light emitting source 122 are turned on, a light spot meeting the light supplementing requirement of the main camera can be fused out, and the central illumination is greater than 70 lux. Figure 8 As shown in FIG. 6, the superimposed A5 light spot fills the light supplementing area of 560mm*746mm (the diagonal length is 50° of the angle range, and the black frame area). Therefore, the A5 light spot meets the light supplementing requirement of the main camera.
