Description

Technical Field

[0001] This application relates to the field of lighting equipment technology, specifically to a light source and a detection device. Background Technology

[0002] A light source is an object or device that can emit light on its own or through other means, either visible light (or electromagnetic waves of a specific wavelength). It is the origin of light and provides the necessary illumination for human vision or optical devices. Taking a product inspection system as an example, the role of the light source is crucial, as it directly affects the quality of image acquisition. Different brightness, different illumination angles, and different colors of light will all affect the images captured by the camera, thereby affecting the detection accuracy, stability, and efficiency of the entire system.

[0003] Therefore, in order to accurately acquire high-quality images, for products of different colors and sizes, it is usually necessary to first determine the lighting angle, spot size, and other conditions for image acquisition through experiments before using camera equipment for product inspection. This involves acquiring images of the product under different lighting conditions using the camera equipment, and then determining the most suitable lighting conditions based on the acquired images. However, existing inspection light sources are mostly of fixed size, which cannot meet the compatibility requirements of multiple scenarios or multiple products. Frequent changes of light sources are required during experiments, making the operation cumbersome and inconvenient. Utility Model Content

[0004] In view of the above problems, this application provides a light source and detection device to meet the compatible use of multiple scenarios or multiple products, avoid frequent replacement of light sources, and simplify operation.

[0005] According to one aspect of the embodiments of this application, a light source is provided, the light source comprising: a main body, a driving component, a plurality of transmission components, and a plurality of light-emitting components; the driving component is rotatably disposed on the main body; the plurality of light-emitting components are arranged circumferentially on the main body along the driving component, and the plurality of light-emitting components are slidably connected to the main body radially along the driving component; the plurality of transmission components are correspondingly connected to the plurality of light-emitting components and the driving component, and the driving component is used to drive the plurality of light-emitting components to synchronously diffuse outward or converge inward along the radial direction of the driving component when rotating.

[0006] In one alternative approach, the driving component is positioned at the center of the main body, and multiple light-emitting components are arranged around the outer periphery of the driving component.

[0007] In one alternative embodiment, the transmission component is a transmission rod, with one end of the transmission rod rotatably connected to the drive component and the other end rotatably connected to the light-emitting component.

[0008] In one alternative embodiment, the main body has a mounting groove, and the transmission component and at least part of the drive component are disposed in the mounting groove; the light-emitting component is disposed on the outside of the bottom wall of the mounting groove and extends into the mounting groove to be connected to the transmission component in a transmission manner; the light source also includes a cover plate, which covers the opening of the mounting groove.

[0009] In one alternative embodiment, the cover plate is used to be fixed in contact with the mounting surface; the drive assembly includes a rotating body, a drive member, and a transmission connector. The rotating body is rotatably disposed on the inner side of the bottom wall of the mounting groove and is drively connected to multiple transmission components; the drive member is movably disposed on the outer surface of the side wall of the mounting groove, and at least a portion of its structure extends into the mounting groove; the transmission connector is rotatably disposed in the mounting groove and is drively connected between the end of the drive member extending into the mounting groove and the rotating body. The rotation axis of the transmission connector is perpendicular to the rotation axis of the rotating body. The drive member is used to drive the transmission connector to rotate during movement, thereby driving the rotating body to rotate through the transmission connector.

[0010] In one alternative embodiment, the rotating body is a bevel gear; the transmission connecting component includes a rotating shaft and a helical gear. The rotating shaft is rotatably mounted in the mounting groove, with one end of the rotating shaft fixedly connected to the driving component and the other end fixedly connected to the helical gear. The helical gear meshes with the bevel gear, and the rotating shaft is used to drive the bevel gear to rotate through the helical gear during rotation.

[0011] In one alternative embodiment, the driving component is a motor, which is fixedly mounted on the outer surface of the sidewall of the mounting slot, and the output end of the motor extends into the mounting slot and is fixedly connected to the transmission connector, so as to drive the transmission connector to rotate through the output end of the motor.

[0012] In one alternative embodiment, a plurality of slide rails extending radially along the drive assembly are provided on the inner or outer side of the bottom wall of the mounting slot. The slide rails are arranged circumferentially along the drive assembly, and each light-emitting component is slidably connected to at least one slide rail.

[0013] In one alternative embodiment, each light-emitting component includes a mounting base and multiple light sources. The mounting base of each light-emitting component is inclinedly disposed on the main body, and the mounting bases of the multiple light-emitting components are generally outwardly flared. The multiple light sources are disposed on opposing inclined surfaces between the mounting bases of the multiple light-emitting components, so that the light emitted by the multiple light sources is concentrated.

[0015] This application embodiment sets a driving component on the main body and arranges multiple light-emitting components that can slide radially along the driving component along the circumference of the driving component. Then, multiple transmission components are connected one-to-one between the multiple light-emitting components and the driving component. This allows the driving component to synchronously control the multiple light-emitting components to slide outward or inward when rotating, thereby changing the overall size formed by the multiple light-emitting components and thus changing the size of the light spot formed by the light emitted by the multiple light-emitting components. This enables the light source to meet the compatibility of multiple scenarios or multiple products, avoids frequent replacement of light sources, and simplifies operation.

[0040] Camera equipment is a core component of product inspection systems, acting like the "eyes of the machine." It provides raw data for subsequent analysis through high-precision imaging. Cameras can capture different images under varying lighting conditions. For example, specific angles, colors, or wavelengths of light can highlight features such as edges, textures, and defects (e.g., scratches, dents) of the object being inspected, while high-brightness lighting can suppress ambient light, ensuring image stability (e.g., in outdoor industrial inspection). Therefore, before using camera equipment for product inspection, it is usually necessary to experimentally determine the optimal lighting conditions for image acquisition to ensure the capture of high-quality images.

[0041] Specifically, during the experiment, different lighting conditions were provided for product testing using a light source. This involved using light spots of different sizes and colors to illuminate the product, then using a camera to capture images of the product under different lighting conditions. The images were then processed using algorithms such as target detection and template matching to complete the product testing. Finally, the most suitable lighting conditions were determined based on the testing results.

[0042] However, existing detection light sources are mostly of fixed size, which often cannot meet the requirements of multiple scenarios or multiple products in the experimental process. It is necessary to frequently change the light source to provide different lighting conditions for the camera equipment, which is cumbersome and inconvenient.

[0043] Based on this, in order to be compatible with the lighting needs of multiple scenarios or multiple products, this application provides a light source, which is composed of multiple light-emitting components, and the size of the light source can be changed by adjusting the distance between the light-emitting components, so that the light emitted by the light source can form light spots of different sizes, thereby providing different lighting conditions for the camera device.

[0044] Specifically, a driving component is rotatably mounted on the main body of the light source. Multiple light-emitting components are arranged circumferentially on the main body and are connected to the driving component via transmission. Multiple light-emitting components are slidably connected to the main body radially along the driving component, so that multiple light-emitting components can move closer to or further away from each other relative to the main body when the driving component rotates, thereby changing the overall size of multiple light-emitting components and providing light spots of different sizes for lighting experiments, thus enabling the light source to be compatible with the lighting needs of multiple scenes or multiple products.

[0045] The light source provided in this application embodiment can be applied not only to product inspection, but also to smart homes, license plate recognition, precision agriculture, machine vision, and other fields to meet the lighting needs of multiple scenarios. For ease of explanation, this application embodiment uses product inspection as an example for illustration.

[0046] Please see Figure 1 and Figure 2 , Figure 1 A stereoscopic view of the light source from one perspective is shown. Figure 2 The partial structure of the light source is shown. The light source 1 includes a main body 10, a driving component 20, multiple transmission components 30, and multiple light-emitting components 40.

[0047] The drive assembly 20 is rotatably mounted on the main body 10. Specifically, the drive assembly 20 can be connected to the main body 10 through a structure of a rotating shaft, bearing, and slewing bearing, so that the drive assembly 20 can rotate relative to the main body 10 in the direction indicated by the double arrow A.

[0048] Further integration Figure 3 and Figure 4, Figure 3 Two perspective views of the light source are shown, with multiple light-emitting components 40 arranged circumferentially on the main body 10 along the driving component 20. The driving component 20 can be ring-shaped and positioned at the edge of the main body 10, while the multiple light-emitting components 40 are arranged around the inner periphery of the driving component 20, allowing the user to directly rotate the driving component 20 from the side for easy adjustment of the light-emitting components 40.

[0049] Of course, the driving component 20 can also be located at the center of the main body 10, with multiple light-emitting components 40 arranged around the outer periphery of the driving component 20. For example... Figure 3 As shown, when multiple light-emitting components 40 approach and abut against each other, the entire group of multiple light-emitting components 40 will form a ring shape, resulting in some remaining space at the center of the main body 10. Setting the driving component 20 at the center of the main body 10 can effectively utilize this remaining space, improve the space utilization rate of the main body 10, and help reduce the overall volume of the light source 1.

[0050] Furthermore, multiple light-emitting components 40 are slidably connected to the main body 10 along the radial direction of the driving component 20, so that the multiple light-emitting components 40 can slide along the radial direction of the driving component 20 to move closer to or further away from each other, thereby changing the overall size formed by the light-emitting components 40. As an example, such as Figure 2 As shown, a first strip hole 11 extending radially along the drive assembly 20 can be opened on the main body 10, and a first connecting part 41 on the light-emitting assembly 40 is inserted into the first strip hole 11. The first connecting part 41 can move along the extension direction of the first strip hole 11, so that the light-emitting assembly 40 moves closer to or further away from the drive assembly 20.

[0051] Of course, a guide rail, sliding rod, or other structure extending radially along the drive component 20 can also be provided on the main body 10, and the light-emitting component 40 can be slidably connected to the guide rail, sliding rod, or other structure, so that the light-emitting component 40 can slide relative to the main body 10. At the same time, the guiding effect of the guide rail, sliding rod, or other structure can be used to control the sliding direction of the light-emitting component 40.

[0052] Multiple transmission components 30 are connected one-to-one between multiple light-emitting components 40 and driving component 20, so as to control the sliding of multiple light-emitting components 40 simultaneously through the rotation of driving component 20. That is, when the driving component 20 rotates, it drives multiple light-emitting components 40 to synchronously diffuse outward or converge inward along the radial direction of driving component 20 through transmission component 30.

[0053] Specifically, with Figure 2Taking the structure shown as an example, the transmission component 30 can be a transmission rod 31. One end of the transmission rod 31 is rotatably connected to the drive component 20, and the other end is rotatably connected to the light-emitting component 40. The rotatable connection between the transmission rod 31 and the drive component 20 and the light-emitting component 40 can be achieved through structures such as bearings and hinges.

[0054] exist Figure 2 Based on the state shown, viewed from a top-down perspective, when the driving component 20 rotates clockwise in the direction indicated by the double arrow A, the end of the transmission rod 31 connected to the driving component 20 gradually approaches the first strip hole 11, and pushes the light-emitting component 40 outward through the end of the transmission rod 31 connected to the light-emitting component 40, causing multiple light-emitting components 40 to diffuse outward, that is, multiple light-emitting components 40 from... Figure 3 The aggregation state transformation shown is Figure 4 The diffusion state shown increases the overall volume of the multiple light-emitting components 40, thereby increasing the size of the light spot formed by the light emitted by the multiple light-emitting components 40.

[0055] Conversely, when the drive assembly 20 rotates counterclockwise in the direction indicated by the double arrow A, the end of the transmission rod 31 connected to the drive assembly 20 gradually moves away from the first strip hole 11, and pulls the light-emitting component 40 inward through the end of the transmission rod 31 connected to the light-emitting component 40, causing multiple light-emitting components 40 to converge and slide inward, that is, multiple light-emitting components 40 from... Figure 4 The diffusion state transformation shown is Figure 3 The aggregation state shown reduces the overall volume of the multiple light-emitting components 40, thereby reducing the light spot formed by the light emitted by the multiple light-emitting components 40.

[0056] Of course, the transmission component 30 can be composed of a transmission rod 31, or it can be composed of a protrusion and an elastic element. The protrusion is disposed on the side wall of the drive component 20, and the end of the protrusion facing the light-emitting component 40 has a beveled surface or an outwardly convex arc surface. The elastic element is connected between the side of the light-emitting component 40 away from the drive component 20 and the main body 10. When the drive component 20 rotates, the protrusion moves closer to the light-emitting component 40 and abuts against the light-emitting component 40 through the beveled surface or arc surface on the protrusion, causing the light-emitting component 40 to slide away from the drive component 20 and compress the elastic element. Alternatively, the protrusion moves away from the light-emitting component 40, and the beveled surface or arc surface on the protrusion separates from the light-emitting component 40, causing the light-emitting component 40 to slide closer to the drive component 20 under the elastic force provided by the elastic element.

[0057] In the above embodiments, by setting a driving component 20 on the main body 10 and arranging multiple light-emitting components that can slide radially along the driving component 20 along the circumference of the driving component 20, and then connecting multiple light-emitting components 40 and the driving component 20 one-to-one through multiple transmission components 30, the driving component 20 can synchronously control the multiple light-emitting components 40 to slide outward or inward when rotating, thereby changing the overall size formed by the multiple light-emitting components 40, thereby changing the size of the light spot formed by the light emitted by the multiple light-emitting components 40. This allows the light source 1 to meet the compatibility of multiple scenarios or multiple products, avoids frequent replacement of light sources, and simplifies operation.

[0058] Regarding the structure of the light-emitting component 40, this application provides one possible implementation method, such as... Figure 5 and Figure 6 As shown, Figure 5 The three-dimensional structure of the light-emitting component is shown. Figure 6 The cross-sectional structure of the light source is shown. Each light-emitting component 40 includes a mounting base 42 and multiple light sources 43. The mounting base 42 of each light-emitting component 40 is inclinedly disposed on the main body 10, and the mounting base 42 of multiple light-emitting components 40 is generally outwardly flared. The multiple light sources 43 are disposed on the inclined surfaces facing each other between the mounting bases 42 of multiple light-emitting components 40, so that the light emitted by the multiple light sources 43 is concentrated, thereby ensuring that the light spot can maintain a state of gradually darkening from the center to the edge regardless of whether the light-emitting component 40 is in a concentrated state or a diffused state, thus ensuring the stability of the light spot shape.

[0059] Specifically, multiple mounting bases 42 can be as follows: Figure 6 The shape shown extends in a similar arc shape, creating inclined surfaces 421 with different angles on opposite sides of the multiple mounting bases 42. As an example, such as... Figure 6 As shown, three inclined surfaces 421 with inclination angles of 80 degrees, 45 degrees and 30 degrees are formed on the opposite side of the multiple mounting bases 42. The inclined surfaces 421 closer to the main body 10 are gentler, and the inclined surfaces 421 further away from the main body 10 are steeper, so that after the multiple light sources 43 are set on the inclined surfaces 421, the light source 1 can emit light at different angles.

[0060] Furthermore, to improve the compatibility of the light source 1, multiple light sources 43 can be composed of LEDs of various colors. For example, multiple light sources 43 may include red, green, and blue LEDs, and the brightness and darkness of different colored LEDs can be controlled individually. This allows the light source 1 to form light spots of different colors and brightnesses through the light emitted by the red, green, and blue LEDs, thus enabling compatibility with products of different colors and broadening its compatibility. Of course, the light sources 43 on different light-emitting components 40 can also be controlled individually, allowing the light source 1 to illuminate the product at different angles through the light-emitting components 40 at different positions.

[0061] Furthermore, in order to protect the drive assembly 20 and the transmission assembly 30, such as Figure 1 , Figure 2 and Figure 6 As shown, the main body 10 has a mounting groove 12, and the transmission component 30 and at least part of the drive component 20 are disposed within the mounting groove 12. Specifically, one end of the drive component 20 is rotatably connected to the bottom wall 121 of the mounting groove 12, while the other end is located outside the mounting groove 12. The transmission component 30 is connected to the portion of the drive component 20 located inside the mounting groove 12, allowing the user to control the rotation of the drive component 20 by operating the portion of the drive component 20 located outside the mounting groove 12. This ensures that the user can normally control the diffusion or aggregation of multiple light-emitting components 40 through the drive component 20 and the transmission component 30.

[0062] As shown in the figure, the light-emitting component 40 is disposed on the outer side of the bottom wall 121 of the mounting groove 12 and extends into the mounting groove 12 for transmission connection with the transmission component 30. As an example, it can be as follows... Figure 2 The structure shown has a first strip hole 11 on the bottom wall 121 of the mounting groove 12 and a first connecting part 41 on the light-emitting component 40. In addition to allowing the first connecting part 41 to extend into the mounting groove 12 and connect with the transmission component 30, the first strip hole 11 can also guide the sliding of the first connecting part 41, ensuring that the light-emitting component 40 can slide radially along the drive component 20 through the first connecting part 41.

[0063] Of course, a through hole can also be opened in the side wall 122 of the mounting groove 12, and a guide rail, sliding rod or slide groove extending radially along the drive assembly 20 can be provided on the inner side of the bottom wall 121 of the mounting groove 12, so that the light-emitting component 40 can pass through the through hole and extend into the mounting groove 12 to be connected to the transmission assembly 30. The part of the light-emitting component 40 that extends into the mounting groove 12 is slidably connected to the guide rail, sliding rod or slide groove, so that the guide rail, sliding rod or slide groove guides the sliding of the light-emitting component 40, ensuring that the light-emitting component 40 can slide radially along the drive assembly 20.

[0064] The light source 1 also includes a cover plate 50, which covers the opening of the mounting groove 12, thereby separating the internal space of the mounting groove 12 from the external environment and preventing the air and moisture in the external environment from affecting the transmission structure between the driving component 20, the transmission component 30 and the light-emitting component 40, so as to protect the driving component 20 and the transmission component 30.

[0065] In addition, the cover plate 50 can also be used to adhere and fix it to a mounting surface, which can be a flat surface such as a wall or ceiling, or a flat surface on the bracket used to mount the light source 1. The cover plate 50 can be adhered and fixed to the mounting surface by means of threaded connection, interference fit, adhesive, magnetic attraction, etc. As an example, for instance... Figure 1 As shown, the cover plate 50 has a mounting hole 51. After the cover plate 50 is fitted with the mounting surface, screws, bolts, etc. are inserted through the mounting surface into the mounting hole 51, and the cover plate 50 and the mounting surface are fixedly connected by threaded connection or interference fit.

[0066] When the cover plate 50 is in contact with the mounting surface, in order to properly control the rotation of the drive component 20 within the mounting groove 12, a user-operable structure needs to be provided outside the mounting groove 12. This structure can be located on the outer side of the bottom wall 121 of the mounting groove 12 or on the outer surface of the side wall 122 of the mounting groove 12. Of course, to avoid the external structure of the mounting groove 12 from affecting the normal operation of the light emitted by the light-emitting component 40, such as... Figure 1 and Figure 2 As shown, a portion of the structure of the drive assembly 20 can be disposed on the outer surface of the side wall 122 of the mounting groove 12.

[0067] Specifically, the drive assembly 20 includes a rotating body 21, a drive component 22, and a transmission connector 23. The rotating body 21 is rotatably disposed on the inner side of the bottom wall 121 of the mounting groove 12 and is connected to multiple transmission components 30. It is the main component of the drive assembly 20 used to control the sliding of the light-emitting component 40 through the transmission components 30.

[0068] The driving component 22 is movably disposed on the outer surface of the side wall 122 of the mounting groove 12, and at least a portion of its structure extends into the mounting groove 12. It is the power source for controlling the rotation of the rotating body 21. The user can operate the driving component 22 to input torque to the rotating body 21, so that the rotating body 21 can rotate relative to the bottom wall 121 of the mounting groove 12. The driving component 22 can be a knob, handwheel, or other structure that the user can turn to input torque to the rotating body 21, or it can be a motor or other device that can automatically input torque.

[0069] Energy transfer between the driving member 22 and the rotating body 21 can be achieved through the transmission connector 23. Specifically, the transmission connector 23 is rotatably disposed in the mounting groove 12 and is connected to the end of the driving member that extends into the mounting groove 12 and the rotating body 21. The rotation axis of the transmission connector 23 is perpendicular to the rotation axis of the rotating body 21. The driving member 22 is used to drive the transmission connector 23 to rotate during movement, thereby driving the rotating body 21 to rotate through the transmission connector 23.

[0070] like Figure 2 As shown, the rotating body 21 needs to rotate in the direction indicated by the double arrow A to control the multiple light-emitting components 40 to diffuse outward or converge inward. The torque input by the driving component 22 is used to control the transmission connector 23 to rotate in the direction indicated by the double arrow B. Therefore, the transmission connector 23 can be composed of structures such as helical gears, bevel gears, and worm gears, so as to convert the torque input by the driving component 22 in the direction indicated by the double arrow B into the torque required to control the rotating body 21 in the direction indicated by the double arrow A.

[0071] In this structure, by setting the driving component 22 on the outer surface of the side wall 122 of the mounting groove 12 and transmitting the torque input by the driving component 22 to the rotating body 21 through the transmission connector 23, the direction of the torque input by the driving component 22 can be changed through the transmission connector 23 after the cover plate 50 is in contact with the mounting surface. This ensures that the rotating body 21 can normally control the diffusion or aggregation of multiple light-emitting components 40. At the same time, the driving component 22 is located on the side wall 122 of the mounting groove 12 and will not interfere with the light emitted by the light-emitting components 40 on the bottom wall 121 of the mounting groove 12.

[0072] Regarding the structure of the driving component 22, this application provides an implementation method, such as... Figure 2 As shown, the driving component 22 can also be a motor 221, such as a forward and reverse motor, a stepper motor, etc. The motor 221 is fixedly installed on the outer surface of the side wall 122 of the mounting groove 12, and the output end of the motor 221 extends into the mounting groove 12 and is fixedly connected to the transmission connector 23 so as to drive the transmission connector 23 to rotate through the output end of the motor 221.

[0073] The motor 221 can also control its output torque through electrical signals. Taking a product inspection system as an example, the control device of the product inspection system can send electrical signals to the motor 221 to control the working process of the motor 221 according to the quality of the image. For example, if the edge of the product in the image is dark, the control device can automatically control the output torque of the motor 221 to make the rotating body 21 diffuse the light-emitting component 40 outward, thereby realizing the automatic adjustment of the light source 1.

[0074] Regarding the structure of the transmission connection component, this application provides an implementation method, such as... Figure 2 and Figure 6 As shown, the rotating body 21 is a bevel gear 211, and the transmission connecting part 23 includes a rotating shaft 231 and a helical gear 232. The rotating shaft 231 is rotatably disposed in the mounting groove 12, and one end of the rotating shaft 231 is fixedly connected to the driving part 22, and the other end is fixedly connected to the helical gear 232. The helical gear 232 meshes with the bevel gear 211.

[0075] The power output from the drive unit 22 can drive the rotating shaft 231 to rotate in the direction indicated by the double arrow B, thereby driving the helical gear 232 to rotate in the same direction. During rotation, the helical gear 232 can drive the bevel gear 211 to rotate through its teeth, causing the bevel gear 211 to drive multiple light-emitting components 40 to diffuse outward or converge inward through the transmission component 30. In this structure, the precise meshing principle of the bevel gear 211 and the helical gear 232 can be used to improve the precise control of the rotation process of the rotating body 21, thereby precisely adjusting the size of the light source 1 according to the requirements.

[0076] Furthermore, to improve the stability of the sliding of the light-emitting component 40, in some embodiments, such as Figure 2 As shown, a plurality of slide rails 123 extending radially along the drive assembly 20 are provided on the inner or outer side of the bottom wall 121 of the mounting groove 12. The plurality of slide rails 123 are arranged circumferentially along the drive assembly 20, and each light-emitting component 40 is slidably connected to at least one slide rail 123.

[0077] The slide rail 123 can be disposed on the same side of the bottom wall 121 of the mounting groove 12 together with the light-emitting component 40, or it can be disposed on the opposite side of the bottom wall 121 of the mounting groove 12. The light-emitting component 40 can be inserted into the mounting groove 12 and slidably connected to the slide rail 123 by making holes in the bottom wall 121.

[0078] Slide rail 123 can be a guide rail, sliding rod, or other structure, as an example. Figure 2 Taking the structure as an example, the slide rail 123 is a sliding rod disposed inside the bottom wall 121 of the mounting groove 12. A second strip-shaped hole 13 extending radially along the drive assembly 20 is provided on the bottom wall 121 of the mounting groove 12. The sliding rod can be fixed above the second strip-shaped hole 13 by a fixing plate 124, or it can be disposed on at least one side of the second strip-shaped hole 13 along the circumference of the drive assembly 20. The second connecting part 44 on the light-emitting component 40 extends through the second strip-shaped hole 13 into the mounting groove 12 and can be slidably sleeved on the sliding rod. When the drive assembly 20 rotates, the second connecting part 44 can slide on the sliding rod as multiple light-emitting components 40 diffuse or converge. This allows the slide rail 123 to guide the sliding of the light-emitting component 40, improving the stability of the sliding process.

[0079] According to another aspect of the embodiments of this application, a detection device is also provided, which includes a device body and a light source as described in any of the above embodiments. The light source is fixedly disposed on the device body and is used to emit light to irradiate the object to be detected on the device body.
