At the same time, the bottom light source works in conjunction with the top light source to ensure that every detail is clearly visible. While achieving high-quality lamp inspection, the brightness of the bottom light source can be appropriately reduced, thereby reducing damage to the inspectors' eyes. The technical solution of this utility model will be described in detail below with reference to specific embodiments:

[0025] Please see Figure 1 , 2 As shown, the lamp inspection device provided in the embodiments of this utility model includes a stage 10, a first light source 20, and a second light source 30; the stage 10 is used to support the object to be inspected. In some embodiments, the stage 10 can be an independent component, such as... Figure 1 As shown, this facilitates the relocation of the light inspection equipment to different locations according to usage requirements. In other embodiments, the platform 10 can also be integrated with the desktop, such as... Figure 2 As shown, this can improve the integration of the light inspection equipment, increase space utilization, and improve the structural stability of the light inspection equipment during use; the first light source 20 is spaced above the stage 10, and the first light source 20 is configured to emit a light beam toward at least a first area on the upper surface of the stage 10; the second light source 30 is mounted on the stage 10, the second light source 30 is a surface light source, the light emitting surface of the second light source 30 is located on the upper surface of the stage 10, and at least a portion of the light emitting surface is located in the first area, which is the placement area of ​​the object to be inspected.

[0026] This invention achieves multi-angle illumination inspection of the object under inspection by setting up a platform 10, a first light source 20, and a second light source 30. The first light source 20 illuminates from above, providing the main illumination, while the second light source 30, as a surface light source, is mounted on the platform 10 to ensure uniform illumination of the bottom and surrounding areas of the object under inspection, thus improving the comprehensiveness and accuracy of the inspection. In addition, the bottom light source works in conjunction with the top light source to appropriately reduce the brightness of the bottom light source while achieving high-quality light inspection, thereby reducing damage to the eyes of the inspectors.

[0027] Please see Figure 1-3 As shown, in an optional embodiment of this utility model, a lifting bracket 40 is further included. The first light source 20 is mounted on the lifting bracket 40. The lifting bracket 40 is configured to adjust the height of the first light source 20 within a preset stroke and to hold the first light source 20 at multiple heights within the preset stroke. This further embodiment, by introducing the lifting bracket 40, allows the height of the first light source 20 to be flexibly adjusted within a preset stroke and to be stably held at multiple height positions. This embodiment enhances the adaptability of the lamp inspection equipment, enabling the illumination distance of the light source to be adjusted according to the size of different inspected objects and inspection requirements, thereby optimizing the lighting effect and improving inspection accuracy. At the same time, the adjustment function of the lifting bracket 40 also improves the versatility and ease of operation of the equipment, making it suitable for more diverse inspection scenarios.

[0028] Please see Figure 1-3 As shown, in an optional embodiment of this utility model, the lifting bracket 40 includes a fixed part 41 and a movable part 42. The fixed part 41 is fixedly disposed relative to the platform 10. In some embodiments, the fixed part 41 can be directly fixedly installed on the platform 10, such as... Figure 1 , 2As shown, this allows the light inspection equipment to be integrated into a whole, facilitating the overall deployment of the light inspection equipment. In other embodiments, the fixed part 41 can also be installed on other fixed brackets or on the ground according to the actual spatial layout needs. The movable part 42 is movably connected to the fixed part 41 in the vertical direction. It should be understood that the movement of the movable part 42 in the vertical direction is necessary, but this does not mean that the movable part 42 can only have this one mode of movement. For example, in a further embodiment, the movable part 42 can also swing along the vertical axis or the horizontal axis to adjust the illumination angle of the first light source 20. A locking mechanism is provided between the movable part 42 and the fixed part 41. The locking mechanism is assembled to be able to hold the movable part 42 in multiple positions within the movement stroke and to release the movable part 42 from multiple positions within the movement stroke.

[0029] This further embodiment optimizes the design of the lifting bracket 40, allowing the fixed part 41 to be flexibly installed on the platform 10, other fixed brackets, or the ground according to actual needs, thus enhancing the deployment adaptability and space utilization of the light inspection equipment. At the same time, the movable part 42 can be flexibly set in terms of its degrees of freedom as needed, further improving the flexibility of light source positioning and the accuracy of detection. The locking mechanism ensures that the movable part 42 can be stably fixed in multiple positions and quickly released, improving the convenience of operation and the stability of the equipment, making the light inspection equipment more adaptable to diverse scenario requirements, and significantly improving detection efficiency and practicality.

[0030] Please see Figure 1-3 As shown, in an optional embodiment of this utility model, one of the fixed part 41 and the movable part 42 includes a support rod, and the other includes a support tube, with the support rod and the support tube being inserted into each other. This further embodiment, by employing a design where the support rod and support tube are inserted into each other, achieves a simple and stable connection between the fixed part 41 and the movable part 42. This structure not only facilitates installation and disassembly but also enhances the overall stability and durability of the lifting bracket 40, while reducing manufacturing costs. The insertion of the support rod and support tube makes the vertical movement of the movable part 42 smoother, further improving the flexibility and accuracy of the height adjustment of the first light source 20, thereby optimizing the ease of operation and detection effect of the lamp inspection equipment. It should be understood that the cooperation method between the fixed part 41 and the movable part 42 is not limited to the part disclosed in this embodiment. For example, in some other embodiments, mutually cooperating slide rails and sliders can be provided on the fixed part 41 and the movable part 42 respectively. Such structures that can limit the directional relative displacement of the two components should be applicable to this utility model.

[0031] Please see Figure 3As shown, in an optional embodiment of this utility model, the locking mechanism includes a screw 43 threadedly connected to the support tube along the radial direction of the support tube. One end of the screw 43 penetrates into the interior of the support tube and abuts against the support rod, while the other end of the screw 43 is provided with a knob 44. This further embodiment utilizes the screw 43 penetrating the support tube and abutting against the support rod to achieve vertical height adjustment and stable fixation of the movable part 42. The knob 44 makes operation more convenient; the user only needs to rotate the knob 44 to quickly lock or release the position of the movable part 42. This not only enhances the stability and adjustment accuracy of the lifting bracket 40 but also simplifies the operation process, improves the efficiency and adaptability of the light inspection equipment, and ensures the reliability and durability of the equipment during the inspection process.

[0032] The specific implementation of the locking mechanism is not unique. For example, in other embodiments, a tapered expansion sleeve with external threads can be provided at the end of the support tube, and a nut can be provided outside the expansion sleeve. The support rod can be locked and released by rotating the nut. Alternatively, multiple radial pin holes can be provided on the support rod and support tube. The movable part 42 can be adjusted and maintained at different heights by aligning different pin holes and inserting a positioning pin into the pin hole.

[0033] Please see Figure 1 , 2 As shown, in an optional embodiment of this utility model, a first brightness adjustment switch 21 is further included, which is electrically connected to the first light source 20. This further embodiment, by adding the first brightness adjustment switch 21, allows the user to flexibly adjust the brightness of the first light source 20 according to detection needs, thereby optimizing the illumination effect and improving detection accuracy and adaptability. The first brightness adjustment switch 21 can be implemented in various ways, such as a knob, slider, button, or digital touchscreen control, allowing the user to choose the most suitable adjustment method based on operating habits and equipment design.

[0034] In an optional embodiment of this invention, the first light source 20 includes a shadowless lamp. The shadowless lamp can, for example, consist of multiple light sources arranged in a ring or array, which uniformly superimpose light through multi-angle illumination, thereby eliminating shadows produced by a single light source. The shadowless lamp provides uniform and shadowless illumination, significantly reducing light obstruction and shadow interference on the surface of the object being inspected, thus improving the accuracy and reliability of the inspection.

[0035] Please see Figure 1 , 2As shown, in an optional embodiment of this utility model, a second brightness adjustment switch 31 is further included, which is electrically connected to the second light source 30. This further embodiment, by adding the second brightness adjustment switch 31, allows the user to flexibly adjust the brightness of the second light source 30 according to detection needs, thereby optimizing the illumination effect on the bottom and surrounding areas of the object being detected, and further improving the comprehensiveness and accuracy of the detection. The second brightness adjustment switch 31 can be implemented in various ways, such as a knob, a slider, a button, or digital touchscreen control, allowing the user to choose the most suitable adjustment method based on their operating habits and equipment design.

[0036] Please see Figure 4 As shown, in an optional embodiment of this utility model, the light-emitting surface of the second light source 30 includes a protective plate. The protective plate includes an outer layer 33 and an inner layer 34. The outer layer 33 is exposed on the upper surface of the stage 10, and the inner layer 34 is located below the outer layer 33. The outer layer 33 is made of a transparent polymer material, such as acrylic (PMMA, polymethyl methacrylate), and the inner layer 34 is made of glass. The second light source 30 also includes LED beads 32 disposed below the inner layer 34. This further embodiment achieves high light transmittance and durability of the light-emitting surface of the second light source 30 by designing a double-layer protective plate structure. The polymer material of the outer layer 33 has impact-resistant and scratch-resistant properties, protecting the glass of the inner layer 34 and the LED beads from damage, while ensuring uniform light transmission. The glass of the inner layer 34 further enhances the stability and clarity of the light. This design not only improves the illumination effect and service life of the second light source 30, but also enhances the reliability and safety of the light inspection equipment during the inspection process, making it suitable for high-precision inspection scenarios.

[0037] In an optional embodiment of this utility model, the second light source 30 includes an eye-protection lamp, which may consist of, for example, a light source, a reflector, a dimming module, and an eye-protection material (such as a diffuser). The light source employs low blue light and flicker-free technology, providing soft and uniform light. The eye-protection lamp has high color rendering and low glare characteristics, effectively reducing visual fatigue during prolonged use and protecting eye health. The second light source 30 is configured to emit a light beam with a color temperature of 7500K-8500K, preferably 8000K.
