Description

Technical Field

[0001] This utility model relates to a stereomicroscope zonal illumination device. Background Technology

[0002] Stereo microscopes use various lighting sources, including natural light and artificial light. However, once an image is formed through the microscope, it often fails to provide sufficient brightness for clear observation of objects, which limits its use. Therefore, stereo microscopes generally require additional lighting. Illumination methods for stereo microscopes typically include transmitted illumination (bottom light source) and reflected illumination (top light source). Top light sources, with their direct illumination, increase brightness and widen the viewing angle, and are widely used in various scenarios.

[0003] However, when using a top light source for macroscopic examination of metal samples with a stereomicroscope, reflection occurs. To solve this problem, a side light source is needed to illuminate the metal sample from the side, effectively reducing reflection and making the features of the metal sample more clearly visible. Currently, the top light source of stereomicroscopes is usually a single, integrated structure, which cannot adjust the position of the light source and cannot provide a side light source, making certain features of the metal sample difficult to observe and analyze. Utility Model Content

[0004] The main objective of this invention is to provide a stereomicroscope zonal illumination device to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] Preferably, the bottom plate of the annular lamp housing has multiple grooves along its circumference, and the lamp plate is disposed in the grooves.

[0008] Preferably, the depth of the groove is less than the thickness of the lamp panel.

[0009] Preferably, the annular lamp housing is provided with an annular partition, the lamp plate is disposed inside the annular partition, and a wire hole is provided on the annular partition at the position corresponding to each lamp plate.

[0010] Preferably, a wire groove is provided between the annular lamp housing and the annular partition, and multiple buckles are provided in the wire groove.

[0011] Preferably, the annular lampshade is disposed inside the annular partition, and a protective cover is provided between the annular lamp housing and the annular partition.

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] like Figures 1-4 As shown, the stereomicroscope zonal illumination device provided in this embodiment includes an annular lamp housing 1, a plurality of lamp plates 2 arranged circumferentially on the bottom plate of the annular lamp housing 1, a power supply 3 arranged on one side of the annular lamp housing 1, an annular lamp cover 4 arranged on the front of the annular lamp housing 1, and a multi-pole single-control switch 5 arranged on the back of the annular lamp housing 1.

[0025] Connect the power supply 3 in series with the neutral wires of multiple lamp panels 2, connect the control wire of each lamp panel 2 to different control holes of the multi-pole single-control switch 5, connect the multiple live wire holes of the multi-pole single-control switch 5 with jumpers, and then connect the live wire of the power supply 3 to the live wire hole on the edge of the multi-pole single-control switch 5. This allows you to switch different lamp panels 2 on and off using the multi-pole single-control switch 5.

[0026] When macroscopically examining metal samples, the lamp panel 2 can be activated according to the required side light source direction, thus providing a precise side light source, effectively reducing reflection, and making the characteristics of the metal sample more clearly visible. Furthermore, multiple lamp panels 2 can be activated simultaneously as a regular direct light source, providing greater flexibility and convenience for observation and analysis.

[0027] In this embodiment, as Figure 3 As shown, the bottom plate of the annular lamp housing 1 has multiple grooves 6 arranged along its circumference, and the lamp plate 2 is arranged in the grooves 6, which helps to fix the lamp plate 2 and ensure its stability.

[0028] In this embodiment, as Figure 1 As shown, the depth of the groove 6 is less than the thickness of the lamp panel 2, which reduces the obstruction of light and improves lighting efficiency.

[0029] In this embodiment, as Figure 1 As shown, an annular partition 7 is provided inside the annular lamp housing 1, and the lamp plate 2 is set inside the annular partition 7. A wire hole 8 is provided on the annular partition 7 at the position corresponding to each lamp plate 2. A wire groove 9 is provided between the annular lamp housing 1 and the annular partition 7. Multiple clips 10 are provided in the wire groove 9, which not only facilitates the arrangement and connection of wires, but also helps to keep the device neat and beautiful.

[0030] In this embodiment, as Figure 1 As shown, the annular lampshade 4 is installed inside the annular partition 7, and a protective cover 11 is provided between the annular lamp housing 1 and the annular partition 7.

[0031] In this embodiment, as Figure 1As shown, the lamp panel 2 has a fan-shaped structure, and four lamp panels 2 are provided. The four lamp panels 2 are located inside the annular lamp housing 1 and are evenly distributed along its circumference to ensure that the light source covers all positions.

[0032] In this embodiment, as Figure 2 As shown, the back and sides of the annular lamp housing 1 are provided with lamp source partition lines 12. After the device is connected to the microscope, the front of the device is facing down to illuminate the sample. The human eye can see the back of the device. The position of each lamp plate 2 is confirmed by the lamp source partition lines 12 so as to better turn on the corresponding lamp plate 2.

[0033] In this embodiment, as Figure 2 As shown, a microscope interface 13 is provided on the back of the ring lamp housing 1. Three threaded holes 14 are provided on the microscope interface 13 along its circumference. Fixing bolts 15 are provided in the threaded holes 14 to facilitate connection with the microscope.

[0034] In summary, in this embodiment, the multiple lamp panels 2 arranged circumferentially along the annular lamp housing 1 are individually controlled by a multi-pole single-control switch 5. During macroscopic examination of metal samples, the lamp panel 2 in the corresponding direction can be selected for activation based on the desired side light source direction, thereby providing a precise side light source, effectively reducing reflection, and making the characteristics of the metal sample more clearly visible. Furthermore, the multiple lamp panels 2 can also be activated simultaneously as a conventional direct light source, providing greater flexibility and convenience for observation and analysis.
