Embodiment one

The circumferential ends of the base 1 are respectively provided with mounting seats 11, and the mounting seats 11 are arranged on the radial outer side of the base 1.
[0018] The inner circumferential surface of the base 1 is provided with a reflecting surface 12, the reflecting surface 12 is arranged opposite to the soft light cover 2, and the outer side of the base 1 is provided with a wiring terminal 6, and the wiring terminal 6 is electrically connected with the plurality of light-emitting diodes 5.
[0019] In use, when detecting surface defects of arc-shaped objects such as pipes, cylindrical containers, etc., the semi-circular light source can provide uniform arc-shaped illumination, making the defects on the surface of the object more clearly visible. For example, detecting cracks, corrosion and other problems on the surface of the pipe, the semi-circular light source can irradiate along the arc-shaped surface of the pipe, reducing shadows and reflections, and improving the accuracy of detection. For arc-shaped electronic components, such as arc-shaped display screens, arc-shaped circuit boards, etc., the semi-circular light source can provide appropriate illumination angles, making the details such as lines and solder joints on the components more obvious, facilitating quality detection.
[0020] Spherical object detection can be completed, such as ball bearings, spherical cameras, etc., the semi-circular light source can irradiate the sphere from different angles, highlighting the profile and surface features of the sphere. For example, detecting surface roughness, scratches and other defects of ball bearings, the semi-circular light source can make the light distribution on the bearing surface more uniform, reducing reflections and shadows, and improving the detection effect. For spherical optical elements such as lenses, mirrors, etc., the semi-circular light source can provide soft illumination to avoid strong reflections and glare, making it easier to detect the surface quality of the components.
[0021] Irregular object detection can be achieved. For irregularly shaped objects, the semi-circular light source can be flexibly adjusted according to the shape of the object to provide appropriate illumination angles and intensity. For example, detecting irregularly shaped objects such as automobile parts, mechanical parts, etc., the semi-circular light source can be adjusted in position and angle to provide good illumination for all parts of the object, improving the comprehensiveness and accuracy of detection. When detecting irregularly packaged products such as food, medicine, etc., the semi-circular light source can adapt to different packaging shapes to ensure that the labels, prints and other information on the surface of the product are clearly readable, while also detecting defects and contamination on the surface of the product.
[0022] Transparent object detection: when detecting transparent objects such as glassware, plastic film, etc., the semi-circular light source can be irradiated from the side, making the edge and internal structure of the transparent object more clearly visible. For example, detecting the wall thickness, bubbles and other problems of glass bottles, the semi-circular light source can produce obvious shadows on the edge of the bottle, facilitating the measurement of wall thickness and the detection of bubbles. For transparent optical elements such as lenses, prisms, etc., the semi-circular light source can provide uniform background illumination, making the surface quality and internal defects of the element more easily detected.
