[0038] like Figure 1 and Figure 3As shown, an embodiment of this application provides a lighting mechanism 100, which is mainly used for illuminating and supplementing light on the product to be photographed.

[0039] The lighting mechanism 100 includes a fixed component 110 and at least one movable component 120.

[0040] The fixing component 110 includes a first light source 111 and a fixing member 112, with the first light source 111 connected to the fixing member 112. The illumination area of ​​the first light source 111 forms the basic illumination area of ​​the lighting mechanism 100.

[0041] It is understandable that when the product size exceeds the range of the basic lighting area, it is necessary to add a supplementary lighting area to increase the total lighting area of ​​the lighting mechanism 100.

[0042] Based on the above, the movable component 120 of this application is disposed on the fixed member 112 and spaced apart from the first light source 111. The movable component 120 includes a telescopic member 122 and a second light source 123. The telescopic member 122 drives the second light source 123 to move in a direction away from or close to the fixed member 112, so as to add a supplementary lighting area on the basis of the basic lighting area and expand the total lighting area of ​​the lighting mechanism 100.

[0043] Specifically, when the telescopic member 122 extends outward, the second light source 123 forms a supplementary lighting area. In the preset direction D1, at least part of the supplementary lighting area is located outside the basic lighting area, thereby increasing the total lighting area of ​​the lighting mechanism 100.

[0044] It is understood that the telescopic member 122 can be extended or retracted multiple times when adjusting the illumination range of the second light source 123. Therefore, when the telescopic member 122 retracts inward, at least part of the supplementary lighting area is located outside the basic lighting area, thereby increasing the total lighting area of ​​the lighting mechanism 100.

[0045] After the photo is taken, the telescopic component 122 retracts to its shortest length, bringing the second light source 123 towards the fixed component 110, reducing the overall volume of the lighting mechanism 100, making the lighting mechanism 100 suitable for devices with limited installation space, and reducing the overall size of the photo taking device.

[0046] In some embodiments, such as Figure 1 As shown, the fastener 112 includes a first surface 1121, a second surface 1122, and a side surface 1123. The first surface 1121 and the second surface 1122 are perpendicular to a preset direction D1, and the first surface 1121 and the second surface 1122 are arranged opposite to each other. The side surface 1123 connects the first surface 1121 and the second surface 1122.

[0047] The first light source 111 is disposed on the first surface 1121, and each moving component 120 is disposed on the first surface 1121, the second surface 1122, or the side surface 1123.

[0048] For example, when the moving component 120 is located on the first surface 1121, the moving component 120 is located on the outer periphery of the first light source 111, and the telescopic component 122 drives the second light source 123 to move closer to or further away from the first light source 111 to avoid interference.

[0049] For example, when the moving component 120 is located on the second surface 1122, the telescopic component 122 drives the second light source 123 to move closer to or further away from the first light source 111, so that the second light source 123 moves to the outside of the basic lighting area of ​​the first light source 111, thereby increasing the total area of ​​the lighting area.

[0050] For example, when the movable component 120 is located on the side 1123, the telescopic component 122 drives the second light source 123 to move closer to or further away from the fixed component 112, so that the second light source 123 moves to the outside of the basic lighting area of ​​the first light source 111, thereby increasing the total area of ​​the lighting area.

[0051] In some embodiments, the moving component 120 further includes a driver 121.

[0052] like Figure 2 and Figure 3 As shown, the drive unit 121 is a servo motor or a cylinder.

[0053] The telescopic member 122 includes a slide rail 1221 and a slider 1222, with the slide rail 1221 connected to the fixing member 112. In this embodiment, the slide rail 1221 is disposed on the housing of the driving member 121, reducing the volume of the lighting mechanism 100 and making the structure of the lighting mechanism 100 more compact.

[0054] The slider 1222 is movably mounted on the slide rail 1221. The output end of the drive member 121 is connected to the slider 1222. The second light source 123 is connected to the slider 1222, thereby realizing the extension and retraction of the telescopic member 122.

[0055] It should be understood that in some embodiments, the telescopic member 122 may use a telescopic rod, telescopic grid or other structure to achieve the telescopic action.

[0056] In some embodiments, such as Figures 1 to 3 As shown, the slider 1222 includes a first connecting part 12221 and a second connecting part 12222.

[0057] In this embodiment, the fastener 112 is plate-shaped.

[0058] The first connecting part 12221 is movably connected to the slide rail 1221, and the second connecting part 12222 is connected to the side of the first connecting part 12221 away from the fixing member 112. The second connecting part 12222 has a misaligned part 12223 relative to the first connecting part 12221. The second light source 123 is connected to the side of the misaligned part 12223 close to the fixing member 112, so that the second light source 123 is housed between the second connecting part 12222 and the fixing member 112, making the structure of the moving component 120 compact and the spatial layout reasonable, and reducing the volume of the lighting mechanism 100.

[0059] In some embodiments, the second connecting portion 12222 is movably connected to the first connecting portion 12221, so that the moving component 120 forms a two-stage telescopic structure of slide rail 1221-first connecting portion 12221 and first connecting portion 12221-second connecting portion 12222, making the moving component 120 more flexible.

[0060] In some embodiments, the extension direction of the second connecting portion 12222 is parallel to the edge of the fixing member 112. In this way, when the telescopic member 122 drives the slider 1222 to move closer to the fixing member 112, the projection of the second light source 123 and / or the second connecting portion 12222 is located inside the fixing member 112 in the preset direction D1, making the structure of the lighting mechanism 100 more compact.

[0061] For example, such as Figure 1 As shown, when the telescopic member 122 is retracted to its shortest position, the projections of the second light source 123 and the second connecting portion 12222 are located within the fixing member 112 in the preset direction D1, making the structure of the lighting mechanism 100 more compact and suitable for installation in shooting devices with limited installation space. In some embodiments, the second light source 123 includes at least one second sub-light source 1231.

[0062] When there are multiple second sub-light sources 1231, each second sub-light source 1231 is arranged at intervals, and at least one second sub-light source 1231 is symmetrically distributed, so that the area of ​​the supplementary lighting area is larger and the light intensity distribution is uniform everywhere.

[0063] The first light source 111 includes at least one first sub-light source 1111.

[0064] When there are multiple first sub-light sources 1111, each first sub-light source 1111 is spaced apart, and at least one first sub-light source 1111 is symmetrically distributed, so that the area of ​​the basic lighting area is larger and the light intensity distribution is uniform everywhere.

[0065] For example, such as Figures 1 to 3As shown, there are two second sub-light sources 1231, each elongated in shape, arranged parallel to each other. In other embodiments, the number and shape of the second sub-light sources 1231 can be set as needed.

[0066] For example, such as Figures 1 to 3 As shown, there are two first sub-light sources 1111, each elongated in shape, and the two first sub-light sources 1111 are arranged in parallel and spaced apart. In other embodiments, the number and shape of the first sub-light sources 1111 can be set as needed.

[0067] It should be noted that when there is only one first sub-light source 1111 or one second sub-light source 1231, the first sub-light source 1111 or the second sub-light source 1231 can be a ring light source, which makes the area of ​​the basic lighting area or the supplementary lighting area larger and the light intensity distribution uniform throughout. Here, ring refers to a two-dimensional shape with closed edges, such as a circle or a rectangle.

[0068] In some embodiments, in a plane perpendicular to a preset direction D1, the center line of the illumination area of ​​the first light source 111 coincides with or intersects the center line of the illumination area of ​​the second light source 123.

[0069] For example, such as Figure 1 As shown, the second light source 123 is positioned facing forward, and the center line of the basic lighting area of ​​the first light source 111 coincides with the center line of the supplementary lighting area of ​​the second light source 123.

[0070] Exemplary examples, in other embodiments, such as Figure 1 As shown, the second light source 123 is positioned to the right, such that the center line of the basic illumination area of ​​the first light source 111 is perpendicular to the center line of the supplementary illumination area of ​​the second light source 123. Of course, the angle formed between the central axis of the basic illumination area of ​​the first light source 111 and the central axis of the supplementary illumination area of ​​the second light source 123 can also be 0° to 90°.

[0071] In some embodiments, the slide rails 1221 of each telescopic member 122 are straight, and the extension directions of each slide rail 1221 are different. The extension direction of each slide rail 1221 intersects with the preset direction D1.

[0072] In other words, by having multiple moving components 120 move the second light source 123 to the outer periphery of the first lighting area, the supplementary lighting area of ​​the second light source 123 surrounds the basic lighting area of ​​the first light source 111, thereby expanding the area and angle of the lighting area and helping to form a clearer image.

[0073] In some embodiments, the lighting mechanism 100 further includes a clamping assembly 130 connected to a first surface 1121 of the fixing member 112, and a photographing area 131 is formed on the side of the clamping assembly 130 away from the fixing member 112.

[0074] The illumination area of ​​the first light source 111 is arranged around the photographing area 131, and the illumination area of ​​the second light source 123 is arranged around the illumination area of ​​the first light source 111, thereby expanding the area and angle of the illumination area of ​​the illumination mechanism 100, which is conducive to forming a clearer image.

[0075] like Figure 2 and Figure 4 As shown, the first light source 111 illuminates the photographing area 131 and the periphery of the photographing area 131. When the second light source 123 extends forward, the second light source 123 can increase the illumination of one side of the front area of ​​the first light source 111.

[0076] like Figure 1 and Figure 2 As shown, the clamping component 130 is located between the two first sub-light sources 1111, making the structure of the lighting mechanism 100 more compact and enabling uniform lighting of the product.

[0077] For example, the clamping component 130 uses negative pressure adsorption to fix the product, reducing the risk of bumps and scratches on the product.

[0078] In some embodiments, the first sub-light source 1111 is a luminaire, and the second sub-light source 1231 is a luminaire or a reflector. It is understood that the first sub-light source 1111 needs to be a luminaire, and the first light source 111 needs to form a basic lighting area.

[0079] Based on this, the second light source 123 forms a supplementary lighting area, and either luminaires or reflectors can increase the lighting area. In actual products, luminaires or reflectors can be selected as needed for the second sub-light source 1231.

[0080] This application also provides a shooting device, which includes the lighting mechanism 100 in any of the above embodiments. Therefore, it has all the beneficial effects of the lighting mechanism 100 in any of the above embodiments, and will not be described in detail here.

[0081] The product to be photographed is fixed in the photographing area 131 of the clamping assembly 130, and the lighting mechanism 100 is used to illuminate the photographing area 131 so that the camera can take pictures of the product in the photographing area 131.

[0082] The first light source 111 generates the basic lighting area, and the second light source 123 generates the supplementary lighting area.

[0083] When the product size exceeds the area of ​​the basic lighting, some parts of the product are not illuminated, resulting in unclear images of certain parts of the product. Therefore, it is necessary to use a second light source 123 to generate supplementary lighting, expanding the total lighting area of ​​the lighting mechanism 100 and making the overall image of the product clearer.

[0084] By repeatedly extending or retracting the telescopic component 122, the illumination range of the second light source 123 is adjusted so that the entire product is illuminated, thereby improving the clarity of the camera image.

[0085] After the camera finishes taking a picture, the telescopic component 122 retracts to its shortest length, bringing the second light source 123 towards the fixed component 110, reducing the overall volume of the lighting mechanism 100, making the lighting mechanism 100 suitable for devices with limited installation space, and reducing the overall size of the photographing device.

[0086] For example, such as Figure 1 , Figure 2 and Figure 4 As shown, the front of the product extends beyond the basic lighting area, causing the second light source 123 to extend forward. The second light source 123 can increase the illumination of the front area of ​​the first light source 111.

[0087] For example, such as Figure 4 As shown, when the left or right side of the product exceeds the range of the basic lighting area, an external moving mechanism, such as a robotic arm, can drive the lighting mechanism 100 to rotate as a whole, so that the illumination position of the second light source 123 is on the left or right side.

[0088] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0089] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
