[0003] The present application belongs to the technical field of optical devices, and specifically relates to a light supplement lamp and an electronic device. BACKGROUND

[0004] With the continuous improvement of the image function of electronic devices such as mobile phones, the demand for taking pictures with electronic devices is also increasing, and the scenes for taking pictures are endless. For scenes such as dark light environment and night scene shooting, it is difficult to take clear photos, and video recording or live streaming scenes are also difficult to have a good experience. Therefore, some electronic devices will set a light supplement lamp to supplement light to ensure that there is a good imaging effect in dark light and night scenes.

[0005] In order to make the appearance of the electronic device more expressive, in the related art, the light supplement lamp is usually designed to have a LOGO type shape of a brand logo (LOGO type, LOGO), thereby improving the recognition and appearance performance of the electronic device. In the related art, a plurality of light sources are usually arranged in the shape of the corresponding LOGO, thereby realizing the light effect of the corresponding shape.

[0006] However, although the multi-light source arrangement scheme can realize the light effect of any shape, it is prone to result in a high cost and poor heat dissipation performance of the light supplement lamp due to the need to set a large number of light sources. Therefore, the use performance of the light supplement lamp in the related art is poor. SUMMARY

[0009] In a second aspect, the application discloses an electronic device, comprising a shell, a circuit board and the light supplement lamp; the light guide column is arranged in the shell, and the first light emitting source is arranged on the circuit board.

[0010] In the embodiment of the application, the light supplement lamp comprises the light guide column, and the light guide column comprises the strip-shaped light outlet surface; at this time, the light guide column can form a larger light outlet area, so that when the light supplement lamp realizes the light outlet effect of the corresponding LOGO shape, the number of light emitting sources can be reduced, so that the manufacturing cost of the light supplement lamp is more favorable to be reduced and the heat dissipation performance is more favorable to be improved, and therefore the light supplement lamp disclosed by the application has better use performance.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0022] 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 data 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.

[0023] The light supplement lamp and electronic device provided by the embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments and application scenarios.

[0024] Please refer to Figs. 1-18, the present application discloses a light supplement lamp 100, the light supplement lamp 100 is applied to electronic equipment, the disclosed light supplement lamp 100 includes a first light source 110 and a light guide column 120.

[0025] The light emitted by the first light emitting source 110 is guided by the light guide column 120 and then emitted by the light guide column 120. Optionally, the first light emitting source 110 can be a light emitting diode (LED) lamp, a high-pressure sodium lamp, a metal halide lamp, or the like. Of course, the first light emitting source 110 of the light supplement lamp 100 can also have other structures, which are not limited herein.

[0026] The light guide column 120 is a strip-shaped structural member, and has a first end 1201 and a second end 1202. The first end 1201 and the second end 1202 are two ends of the light guide column 120 arranged opposite to each other along the extension direction of the light guide column 120. The light guide column 120 includes a first light entrance surface 121, a strip-shaped light exit surface 122, a first reflecting surface 123, and a second reflecting surface 124. The extension direction of the strip-shaped light exit surface 122 is the same as the extension direction of the light guide column 120. In this case, it can be understood that the length direction of the strip-shaped light exit surface 122 is the same as the length direction of the light guide column 120, so that the light guide column 120 has a large light exit area.

[0027] The first reflecting surface 123 is located on the end surface of the first end 1201 of the light guide column 120, that is, the first reflecting surface 123 is arranged at the first end 1201 of the light guide column 120. The first light entrance surface 121 and the second reflecting surface 124 are both located on the side of the light guide column 120 away from the strip-shaped light exit surface 122, and the first light entrance surface 121 is located at a position close to the first reflecting surface 123 of the light guide column 120. The opposite side edges of the first reflecting surface 123 respectively meet the strip-shaped light exit surface 122 and the first light entrance surface 121. In the embodiments disclosed in the present application, the extension direction of the light guide column 120 can be the length direction of the light guide column 120. At this time, the first end 1201 and the second end 1202 are two ends distributed along the length direction, and the first light entrance surface 121 and the first light exit surface are arranged along the thickness direction or the height direction of the light guide column 120. It can also be understood that the first light entrance surface 121 and the strip-shaped light exit surface 122 are arranged along the direction perpendicular to the extension direction of the light guide column 120.

[0028] In the direction from the first end 1201 to the second end 1202, the distance between the strip-shaped light exit surface 122 and the second reflecting surface 124 gradually decreases. At this time, an acute angle is formed between the strip-shaped light exit surface 122 and the second reflecting surface 124, so that the end surface area of the first end 1201 of the light guide column 120 is greater than the end surface area of the second end 1202. It can also be understood that the light guide column 120 has a wedge-shaped structure, and the second reflecting surface 124 can be an inclined surface of the wedge-shaped surface of the wedge-shaped structure.

[0029] The first light emitting source 110 is arranged opposite to the first light entrance surface 121. At this time, in the specific light supplement process, the light emitted by the first light emitting source 110 is reflected by the first reflecting surface 123 and the second reflecting surface 124 and then emitted from the strip-shaped light exit surface 122.

[0030] In the embodiments disclosed in the present application, the light supplement lamp 100 comprises a light guide column 120, and the light guide column 120 comprises a strip-shaped light emitting surface 122, so that the light guide column 120 can form a larger light emitting area, and thus the number of light emitting sources can be reduced when the light supplement lamp 100 realizes the light emitting effect of the corresponding LOGO shape, thereby reducing the manufacturing cost of the light supplement lamp 100 and improving the heat dissipation performance, and thus the light supplement lamp 100 disclosed in the present application has better use performance.

[0031] In addition, since the second reflecting surface 124 can be an inclined wedge-shaped surface, the second reflecting surface 124 can cover the end surface of the first end 1201 as much as possible, that is, the first reflecting surface 123, so that the light reflected by the first reflecting surface 123 covers the second reflecting surface 124 as uniformly as possible, thereby making the light more uniformly incident on the second reflecting surface 124, and further improving the light emitting uniformity of the light supplement lamp 100.

[0032] In the present application, one first light emitting source 110 and one light guide member can constitute one strip-shaped light supplement member, and through the combination of a plurality of strip-shaped light supplement members, a soft light lamp of any shape can be realized. For example, according to the shape of the corresponding LOGO, a plurality of light guide columns 120 can be arranged in parallel or intersected at intervals, so as to enclose the shape of the corresponding LOGO. Alternatively, a plurality of light guide columns 120 can enclose a hollow structure, so as to realize ring-shaped light emission. In the case of one strip-shaped light supplement member, the light effect formed is as shown in FIG. 14, and in the case of a plurality of strip-shaped light supplement members, the light effect formed can be as shown in FIG. 15. Of course, other light effects can also be formed, which are not limited herein.

[0033] In one scheme, each strip-shaped light supplement member can be correspondingly arranged with one side of the camera decoration ring, so that the light supplement lamp 100 can form a frame structure with a size similar to that of the camera decoration ring, thereby improving the fitting degree of the light supplement lamp 100 and the camera decoration ring, and further making the light supplement lamp 100 and the camera decoration ring have higher coordination, thereby improving the appearance consistency of the electronic device.

[0034] For example, in the case of a rectangular structure of the camera decoration ring, each strip-shaped light supplement member can correspond to one side of the rectangular structure, so that the light supplement lamp 100 also has a rectangular structure, thereby making the light supplement lamp 100 and the camera module have higher adaptability and better consistency.

[0035] At this time, the light supplement lamp 100 can be a hollow frame structure, and at this time, the hollow area of the light supplement lamp 100 can be used to stack the camera module. Therefore, the light supplement lamp 100 disclosed in the present application can reduce the stacking volume between the light supplement lamp 100 and other devices in the electronic device, thereby reducing the volume of the electronic device.

[0036] In addition, the light supplement lamp 100 in the present application uses multiple same and independent strip-shaped light supplement members to form a hollow frame structure, at this time, each strip-shaped light supplement member can emit light individually or simultaneously, thus multiple different light supplement states can be realized, thereby improving the use performance of the electronic device.

[0037] In the above scheme, the first reflecting surface 123 and the second reflecting surface 124 can be silver-coated reflecting surfaces, of course, the first reflecting surface 123 and the second reflecting surface 124 can also be other reflecting structures, which are not limited herein.

[0038] In another optional embodiment, the second reflecting surface 124 can include multiple tooth-shaped structures 1241, and the multiple tooth-shaped structures 1241 can be arranged continuously along the extension direction of the light guide column 120. At this time, the groove wall of each tooth-shaped structure 1241 can reflect light, thus the reflection angle of the light can be controlled accurately by optimizing the angle of the groove wall, thereby improving the light guiding performance of the second reflecting surface 124.

[0039] In this scheme, by setting multiple tooth-shaped structures 1241 on the second reflecting surface 124, the accurate light guiding of the light before light emission can be realized, thereby the optical performance of the light supplement lamp 100 can be further improved.

[0040] In addition, the tooth-shaped structure 1241 has a simple shape structure, and multiple tooth-shaped structures 1241 are machined in the same plane, thus compared with the scheme in which the second reflecting surface 124 is an arc surface, the machining difficulty of the second reflecting surface 124 in this scheme is smaller. In addition, compared with the second reflecting surface 124 with a plane structure, the second reflecting surface 124 in this scheme has a better light guiding effect.

[0041] Further, the shapes of the multiple tooth-shaped structures 1241 can be the same, that is, the tooth height and tooth width of each tooth-shaped structure 1241 are the same, at this time, since the second reflecting surface 124 is an inclined surface, thus in the direction from the first end 1201 to the second end 1202, the distance between the tooth top of each tooth-shaped structure 1241 and the strip-shaped light emitting surface 122 gradually decreases.

[0042] In this scheme, all the tooth-shaped structures 1241 are arranged in a stepped manner in the direction from the first end 1201 to the second end 1202. At the end of the light guide column 120 away from the first reflecting surface 123, the distance between the tooth top of the tooth-shaped structure 1241 and the strip-shaped light emitting surface 122 is small, so that the light rays with large angles can be received. At the end of the light guide column 120 close to the first reflecting surface 123, the distance between the tooth top of the tooth-shaped structure 1241 and the strip-shaped light emitting surface 122 is large, so that the light rays with small angles can be received. Therefore, the tooth-shaped structure 1241 of the second reflecting surface 124 in this scheme can be covered by the light rays reflected by the first reflecting surface 123 as much as possible, so that the light rays can be more uniformly incident on each tooth-shaped structure 1241, thereby further improving the light emitting uniformity of the light supplement lamp 100, and further improving the optical performance of the light supplement lamp 100.

[0043] In another scheme, the tooth-shaped structure 1241 can be a straight tooth. At this time, a plurality of straight teeth are arranged in parallel.

[0044] In another optional scheme, each tooth-shaped structure 1241 can be an arc-shaped tooth. In the extension direction of the tooth-shaped structure 1241, which can also be understood as the width direction of the light guide column 120, the distance between the tooth top of the tooth-shaped structure 1241 and the strip-shaped light emitting surface 122 can increase from the center of the tooth-shaped structure 1241 to both ends of the tooth-shaped structure 1241. That is, the distance between both ends of each tooth-shaped structure 1241 and the strip-shaped light emitting surface 122 is greater than the distance between the center region of each tooth-shaped structure 1241 and the strip-shaped light emitting surface 122. At this time, it can also be understood that each tooth-shaped structure 1241 is in an arc shape.

[0045] In this scheme, the arc-shaped tooth-shaped structure 1241 can make the light rays scatter outward, so as to increase the reflection range of the reflecting surface, and thereby make the brightness of the center region and the edge region of the strip-shaped light emitting surface 122 similar.

[0046] In another optional scheme, the first reflecting surface 123 can be an arc-shaped surface. At this time, the arc-shaped surface has a better regulation effect on the light rays than the planar structure, so that the arc-shaped surface of the first reflecting surface 123 can further improve the light control effect of the first reflecting surface 123.

[0047] Further, the first edge line a is formed by the intersection of the first reflective surface 123 and the first light-incident surface 121. The light guide column 120 has a first curve b, and the first curve b intersects the first edge line a. The first reflective surface 123 can be formed by the first edge line a along the first curve b. As shown in FIG. 17, the first reflective surface 123 is a cylindrical surface according to the forming method of the first reflective surface 123. According to the definition of the cylindrical surface, the cylindrical surface is formed by a moving line along a fixed curve, the moving line is called the generatrix of the cylindrical surface, and the fixed curve is called the directrix of the cylindrical surface. Therefore, the first curve b in the above is the directrix, and the first edge line a is the generatrix. Therefore, the first reflective surface 123 is formed by the first edge line a along the first curve b. The first edge line a in this embodiment can also be understood as the intersection line of the first reflective surface 123 and the first light-incident surface 121. The first curve b and the first edge line a can determine the surface profile of the first reflective surface 123. Of course, the first edge line a can also be used to control the width of the first reflective surface 123.

[0048] In this scheme, the first reflective surface 123 is formed by the first edge line a along the first curve b. Therefore, the line type of the first curve b can be optimized to further optimize the surface profile of the first reflective surface 123, so as to realize precise light guiding, and further enable the light to reach the strip-shaped light-out surface 1221 with the least number of reflections and the largest light efficiency, so as to further improve the light energy emitted from the strip-shaped light-out surface 122, thereby further improving the optical performance of the light supplement lamp 100.

[0049] In one scheme, the first curve b can be determined by first deriving an initial line type of the first curve b, and then optimizing the initial line type. As known from optical principles, as shown in FIG. 18, a reflecting concave surface converges light rays, and light emitted from any point S on the focal plane P of the reflecting concave surface can exit as parallel light after being reflected by the reflecting concave surface. The focal length f (the distance from the spherical vertex O to the focal plane P) of the reflecting concave surface is f = 1 / 2R, where R is the radius of the reflecting concave surface. In order to make the light emitted by the light source S exit as parallel light after being reflected by the reflecting concave surface, the initial directrix of the first reflecting surface 123 is determined as a circular arc, and the distance from the light source S to the vertex o of the reflecting surface is the focal length f of the first reflecting surface 123. Here, the light source S can be understood as the first light emitting source 110 described above. According to optical principles and geometric relationships, the angle θ between the parallel light and the optical axis is θ = arctan(h / f), where h is the offset of the light source to the optical axis. Therefore, according to the stacking space limitation, the distance f from the light source to the vertex of the reflecting surface is obtained, and the radius of the directrix of the first reflecting surface 123 and the parallel light exit angle are derived. However, in an actual optical system, the first light emitting source 110 is not an ideal point, and the light emitted by the first light emitting source 110 is scattered. Therefore, the light source can be considered as a light emitting surface with a certain size, and thus the initial structure is not the optimal solution, and multiple iterations are required to obtain the optimal structure.

[0050] In one specific scheme, the parameters of the first curve b are shown in Table 1 below:

[0051] Table 1

[0052] The data parameters in Table 1 above can determine the first curve b, and the first edge line a is translated along the first curve b to form the surface profile of the first reflecting surface 123. Of course, the maximum curvature, the minimum curvature, the angle between adjacent surfaces, and the curve length of the first curve b are not limited to the data in Table 1. The data parameters of the first curve b can float within plus or minus ten percent.

[0053] Of course, the first curve b in the above embodiments is not limited to a spline curve, but can also be a Bezier curve. The Bezier curve can be determined by the starting point position, the starting point tangent angle, the starting point tangent length, the ending point position, the ending point tangent angle, and the ending point tangent length.

[0054] In the above embodiments, the light guide column 120 can be machined to have a corresponding surface structure of the first reflecting surface 123, and then a reflective material is coated in the corresponding area to form the first reflecting surface 123.

[0055] In the above embodiment, the partial angle light rays incident on the second reflecting surface 124 are easily emitted out of the light guide column 120 through the tooth-shaped structure 1241, thereby reducing the light utilization efficiency of the light supplement lamp 100. Based on this, in another alternative embodiment, the light supplement lamp 100 can further include a first reflecting member 130 disposed on one side of the light guide column 120 and opposite to the second reflecting surface 124. The first reflecting member 130 can have a third reflecting surface located on the side of the first reflecting member 130 facing the light guide column 120.

[0056] In this scheme, the large angle light rays passing through the tooth-shaped structure 1241 can be returned into the light guide column 120 by the first reflecting member 130, thereby improving the light utilization efficiency of the light supplement lamp 100, and at the same time, further improving the luminous brightness of the light supplement lamp 100.

[0057] In another embodiment, the orthographic projection of the first light-incident surface 121 along the direction perpendicular to the extension direction of the light guide column 120 is located within the orthographic projection of the first reflecting surface 123. This scheme can make as much as possible all the light emitted by the first light-emitting source 110 be directed to the first reflecting surface 123, thereby further avoiding the waste of light, and thus improving the light utilization rate of the light supplement lamp 100.

[0058] Further, the orthographic projection of the strip-shaped light-emitting surface 122 is located within the orthographic projection of the second reflecting surface 124. This scheme can make more light be reflected to the strip-shaped light-emitting surface 122, thereby further improving the optical performance of the light supplement lamp 100.

[0059] When the scheme disclosed in FIG. 1 of the present application is subjected to an illuminance distribution experiment of the projection surface at a projection distance of 1000 mm, the coverage field of view of the light supplement lamp 100 is rectangular, the maximum field of view is ±30°, and it can be seen that the illuminance uniformly decays with the increase of the field of view, satisfying the image light supplement requirement.

[0060] In another alternative scheme, the light supplement lamp 100 can further include a first lens 141 and a first light-shielding member 142, the first light-shielding member 142 can be located between the first lens 141 and the light guide column 120, the first light-shielding member 142 can be provided with a first strip-shaped light-transmitting hole 1421, and the strip-shaped light-emitting surface 122 and the first strip-shaped light-transmitting hole 1421 can be oppositely disposed.

[0061] In this scheme, the first light-shielding member 142 can cover the area on the side surface of the light guide column 120 except the strip-shaped light-emitting surface 122, thereby making the appearance of the light supplement lamp 100 more close to the appearance color of the shell of the electronic device, and thereby improving the appearance consistency of the electronic device.

[0062] Optionally, the first light shielding member 142 can be an ink silk screen structure, and can also be other light shielding structures, which are not limited herein. The first lens 141 is made of a transparent material, such as transparent glass, transparent resin, and the like. It can also be understood that the first lens 141 is an exposed component of the light supplement lamp 100.

[0063] In the embodiments disclosed in the present application, the light guide column 120 has a first surface and a second surface arranged along the thickness or height direction thereof. Both the first surface and the second surface are strip-shaped surfaces. At this time, the first surface as a whole can be a strip-shaped light emitting surface 122, part of the second surface forms a second reflecting surface 124, and the other part forms a first light entering surface 121. Alternatively, a local region of the first surface is subjected to silk screen printing, and the region not subjected to silk screen printing forms the strip-shaped light emitting surface 122.

[0064] In another alternative embodiment, the light supplement lamp 100 can further include a light guide cover 150 and a second light emitting source 160. The light guide cover 150 is a light transmission component, and the light emitted by the second light emitting source 160 is transmitted through the light guide cover 150. Specifically, the light guide cover 150 has a first surface 1501 and a second surface 1502 arranged oppositely. The first surface 1501 can be the top surface of the light guide cover 150, and the second surface 1502 can be the bottom surface of the light guide cover 150. The first surface 1501 is provided with an annular light emitting surface 151 and a fourth reflecting surface 152, and the annular light emitting surface 151 is arranged around the fourth reflecting surface 152. The second surface 1502 is provided with a second light entering surface 153 and a fifth reflecting surface 154, and the second light entering surface 153 can be arranged around the fifth reflecting surface 154. The second light entering surface 153 is arranged oppositely to the fourth reflecting surface 152.

[0065] The second light emitting source 160 is arranged oppositely to the second light entering surface 153. The light emitted by the second light emitting source 160 is reflected by the fourth reflecting surface 152 and the fifth reflecting surface 154 and then emitted from the annular light emitting surface 151. Optionally, the second light emitting source 160 can be an LED lamp, a high-pressure sodium lamp, a metal halide lamp, and the like. Of course, the second light emitting source 160 of the light supplement lamp 100 can also be other structures, which are not limited herein.

[0066] Specifically, in the light supplement process, the light emitted by the second light emitting source 160 enters the second light entering surface 153 and then enters the light guide cover 150. After being transmitted in the light guide cover 150, the light is emitted from the annular light emitting surface 151 of the light guide cover 150 to form a light ring with soft light feeling and moderate brightness on the annular light emitting surface 151, and the light ring can continuously emit light.

[0067] In this scheme, the light guide cover 150 can achieve a ring-shaped light effect, and the light guide column 120 can achieve a rectangular light effect. Therefore, through the combination of the light guide cover 150 and the light guide column 120, the light supplement lamp 100 can achieve a complex light effect, thereby further reducing the number of light sources when the light supplement lamp 100 achieves the light effect of the corresponding LOGO shape, and thus more conducive to reducing the manufacturing cost of the light supplement lamp 100 and improving the heat dissipation performance, thereby further improving the use performance of the light supplement lamp 100.

[0068] In the above embodiment, the combination of the light guide cover 150 and the light guide column 120 can achieve a "D" shape, a "G" shape, and a "Q" shape light effect. Of course, other ring-shaped and linear combined light effects can also be achieved.

[0069] In the above scheme, the light guide cover 150 and the light guide column 120 can be stacked and matched. In a specific scheme, the light guide column 120 can be located above the light guide cover 150. At this time, the light guide column 120 covers part of the light emitting area of the light guide cover 150, and the uncovered area and the light emitting area of the light guide column 120 correspondingly form a light emitting shape.

[0070] However, the thickness of the stacked light guide cover 150 and light guide column 120 is large, and the light emitted by the part of the light guide cover 150 covered by the light guide column 120 will interfere with the light emitting effect of the light guide column 120. Based on this, in another optional scheme, the light guide cover 150 can be provided with a receiving notch 155, the receiving notch 155 can penetrate the ring-shaped light emitting surface 151 and the fifth reflecting surface 154 along the central axis direction of the second light source 160; At least part of the light guide column 120 can be located in the receiving notch 155, and the direction of the strip-shaped light emitting surface 122 is the same as the direction of the ring-shaped light emitting surface 151.

[0071] In this scheme, the light guide column 120 can be embedded in the receiving notch 155 of the light guide cover 150, thereby reducing the stacking thickness of the light guide cover 150 and the light guide column 120, and thus reducing the overall thickness of the light supplement. In addition, the area of the light guide cover 150 interfering with the light guide column 120 is cut off, thereby reducing the interference with the light guide column 120, and further improving the optical performance of the light supplement lamp 100.

[0072] In a specific manufacturing process, the annular light-out surface 151, the fourth reflecting surface 152, the second light-in surface 153 and the fifth reflecting surface 154 are first formed on the light guide cover 150, and then part of the material on the light guide cover 150 is removed to form the accommodating gap 155. At this time, one or more of the annular light-out surface 151, the fourth reflecting surface 152, the second light-in surface 153 and the fifth reflecting surface 154 are damaged, and the annular light-out surface 151, the fourth reflecting surface 152, the second light-in surface 153 and the fifth reflecting surface 154 form a gap. At this time, the annular light-out surface 151, the fourth reflecting surface 152, the second light-in surface 153 and the fifth reflecting surface 154 can be in a semi-annular or fan-shaped structure.

[0073] As shown in FIG. 7, the annular light-out surface 151, the fourth reflecting surface 152, the second light-in surface 153 and the fifth reflecting surface 154 are formed on the light guide cover 150 and are symmetric about the center of the center optical axis of the second light-emitting source 160. Since the fourth reflecting surface 152 is close to the center of the light guide cover 150, the fourth reflecting surface 152 is not damaged, and the remaining annular light-out surface 151, the second light-in surface 153 and the fifth reflecting surface 154 are all cut to form a gap. Therefore, the annular light-out surface 151, the second light-in surface 153 and the fifth reflecting surface 154 form a semi-annular or fan-shaped structure. Then, the light guide column 120 is located in the accommodating gap 155, thereby forming a "Q" shaped structure, and thus the light effect of the "Q" shaped structure can be emitted.

[0074] In another optional solution, the fifth reflecting surface 154 can be provided with a plurality of annular teeth arranged in series, and the annular teeth can extend along the circumference of the second light-in surface 153. In this solution, the sidewall of each annular tooth can precisely control the light, and thus by optimizing the angle of the sidewall of the annular tooth, the refraction angle of the light can be precisely controlled, so that the emitted light of the second light-emitting source 160 is closer to the center position of the annular light-out surface 151, and thus the light supplement performance of the light supplement lamp 100 can be improved.

[0075] In an optional solution, the fourth reflecting surface 152 is a second curve that rotates one revolution around the center optical axis of the second light-emitting source 160. Here, the second curve is the surface linearity of the fourth reflecting surface 152, and the surface profile of the fourth reflecting surface 152 in the present application is obtained by rotating the corresponding second curve one revolution around the center optical axis of the second light-emitting source 160.

[0076] In an optional solution, as shown in FIG. 7, the parameters of the second curve are shown in Table 2 below:

[0077] Table 2

[0078] The data parameter coordinates in Table 2 can determine a second curve, and the second curve is obtained by rotating around the central optical axis of the second light emitting source 160 for one circle, so as to obtain the surface profile of the fourth reflecting surface 152. Of course, the maximum curvature, minimum curvature and curve length of the second curve are not limited to the data in Table 2. The data parameters of the second curve can float between plus or minus ten percent.

[0079] Of course, the second curve in the above embodiment is not limited to a spline curve, but can also be a Bezier curve. The Bezier curve can be determined by the starting point position, the starting point tangent angle, the starting point tangent length, the ending point position, the ending point tangent angle, the ending point tangent length and the like.

[0080] In another alternative, the light supplement lamp 100 can further include a second lens 171 and a second light shielding member 172, and the light guide cover 150 and the light guide column 120 can be located on the side of the second light shielding member 172 away from the second lens 171, and the second light shielding member 172 is provided with an arc-shaped light transmission hole 1721 and a second strip-shaped light transmission hole 1722. The second strip-shaped light transmission hole 1722 can be located between the two ends of the arc-shaped light transmission hole 1721, and the second strip-shaped light transmission hole 1722 extends from the inside of the arc-shaped light transmission hole 1721 to the outside of the arc-shaped light transmission hole 1721. At this time, the arc-shaped light transmission hole 1721 and the second strip-shaped light transmission hole 1722 form a “Q”-shaped light transmission structure, which cooperates with the “Q”-shaped light emitting surface formed by the light guide cover 150 and the light guide column 120, so that the light supplement lamp 100 emits a “Q”-shaped light effect. The “Q”-shaped light effect is shown in FIG. 16.

[0081] In this scheme, the second light shielding member 172 can cover the area on the side surface of the light guide column 120 and the light guide cover 150 away from the second lens 171 except the “Q”-shaped light emitting surface, so that the appearance of the light supplement lamp 100 is closer to the appearance color of the shell of the electronic device, thereby improving the appearance consistency of the electronic device.

[0082] Alternatively, the second light shielding member 172 can be an ink screen printing structure, and of course can also be other light shielding structures, which are not limited herein. The second lens 171 is made of a transparent material, for example, transparent glass, transparent resin and the like. Here, it can also be understood that the second lens 171 is the exposed component of the light supplement lamp 100.

[0083] In another alternative embodiment, the light supplement lamp 100 can further comprise a second reflector 180, the second reflector 180 can be disposed on the second surface 1502, the second reflector 180 can have a sixth reflecting surface, the sixth reflecting surface can be located on a side of the second reflector 180 facing the second surface 1502, the second reflector 180 can be provided with a clearance hole 181 and a clearance notch 182, the clearance hole 181 is disposed opposite to the second light emitting source 160, and the clearance notch 182 is disposed opposite to the first light emitting source 110. The clearance hole 181 is used to avoid the second light emitting source 160, so that the second light entrance surface 153 is exposed, so that the light emitted by the second light emitting source 160 can be incident from the second light entrance surface 153. The clearance notch 182 is used to avoid the first light emitting source 110, so that the first light entrance surface 121 is exposed, so that the light emitted by the first light emitting source 110 can be incident from the first light entrance surface 121.

[0084] In this scheme, the large-angle light passing through the second reflecting surface 124 and the fifth reflecting surface 154 can be returned to the light guide column 120 and the light guide cover 150 by the second reflector 180, thereby improving the light utilization efficiency of the light supplement lamp 100, and further improving the luminous brightness of the light supplement lamp 100.

[0085] In another alternative embodiment, the light supplement lamp 100 can further comprise a diffusion film, the diffusion film can cover the annular light exit surface 151 and the strip-shaped light exit surface 122. In this scheme, the diffusion film can scatter the light emitted from the annular light exit surface 151 and the strip-shaped light exit surface 122, so that the light emitted by the light supplement lamp 100 is more soft, and the light exit field angle of the light supplement lamp 100 can be increased.
