[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-8This utility model provides a technical solution: a multi-purpose automatic light source for a high-power microscope, comprising a multi-purpose automatic light source body 1, a top cover 2 on the multi-purpose automatic light source body 1, and a connecting hole 201 at the upper end of the top cover 2. A microscope connecting seat 6 with a circular structure is connected to the upper end of the top cover 2, and the microscope connecting seat 6 and the connecting hole 201 are coaxial. A base 9 is bolted to the bottom of the top cover 2, and the top cover 2 and the base 9 form a rectangular three-dimensional structure. This structure allows the multi-purpose automatic light source body 1 to form a detachable outer shell structure through the top cover 2 and the base 9. The microscope connecting seat 6 is fixed to the top cover 2, allowing the top cover 2 to be installed on the microscope through the microscope connecting seat 6, so that the multi-purpose automatic light source body 1 provides a light source for the microscope's inspection use. The top cover 2 has interconnected... The system includes a first condenser lens 4 and a second condenser lens 7, with mutually perpendicular first condenser lens grooves 401 and 701 respectively. A beam splitter 5, tilted at 45°, is mounted between the first condenser lens groove 401 and the second condenser lens groove 701. The beam splitter 5 is located at the intersection of the first condenser lens groove 401 and the second condenser lens groove 701. The top cover 2 has mounting slots 202 and power outlets 203 on opposite sides. The mounting slots 202 are elongated structures, allowing connection to an automatic light source controller via the power outlet 203. This enables the controller to arbitrarily control the lighting, allowing the multi-purpose automatic light source 1 to provide single or simultaneous illumination. The LEDs in the first LED lamp mounting base 3 and the second LED lamp mounting base 8... The lamps can be selected from LEDs with different color temperatures or adjustable color temperatures. The first LED lamp mounting base 3 and the second LED lamp mounting base 8 are located on the side and below, respectively, providing light sources from different directions. Since the beam splitter 5 is located at the intersection of two optical paths, under the reflection and transmission effects of the beam splitter 5, the light from one optical path is incident on the beam splitter 5 at a 45-degree angle, and then reflected 90 degrees into the direction of the other optical path. At the same time, the light from the second optical path is also incident on the beam splitter 5 at a 45-degree angle, and part of it is transmitted through, coinciding with the first optical path, thus achieving coaxial optical paths. The two optical paths can also be used separately. The first connecting base 40 is integrally provided on the side of the first condenser lens 4 and below the second condenser lens 7. 2. The first condenser lens 4 is fixed to the top cover 2 with bolts, and the connecting surfaces of the first condenser lens 4 and the second condenser lens 7 are inclined at 45°. This structure, through the tight connection of the first condenser lens 4 and the second condenser lens 7, allows both the first condenser lens 4 and the second condenser lens 7 to be stably installed relative to the top cover 2. The beam splitter 5 is inclined relative to the connecting surfaces of the first condenser lens 4 and the second condenser lens 7, which can be used for cleaning and positioning the beam splitter 5. The first condenser lens groove 401 has an L-shaped structure, and the longitudinal channel of the first condenser lens groove 401 and the connecting hole 201 are coaxial. This structure, through the correspondence between the first condenser lens groove 401 and the connecting hole 201, ensures that the light path of the multi-purpose automatic light source body 1 ultimately faces the microscope connecting seat 6.The light source acts on a high-powered microscope, and the first connecting seat 402 and the second connecting seat 702 are respectively fixed with the first LED lamp mounting seat 3 and the second LED lamp mounting seat 8 via threaded structures. The second connecting seat 702 has a snap-fit ​​positioning groove 703 on its side, and the snap-fit ​​positioning groove 703 has a semi-circular structure. The snap-fit ​​positioning groove 703 corresponds to the mounting slot 202. This structure allows different optical lenses, such as polarizers, to be installed into the second connecting seat 702 from outside the multi-purpose automatic light source body 1 via the snap-fit ​​positioning groove 703 and the mounting slot 202. Different wavelength filters can also be built in.

[0025] Working principle: When using this high-powered microscope multi-purpose automatic light source, firstly, LED lights are installed in the first LED light mounting base 3 and the second LED light mounting base 8 respectively. Then, the first LED light mounting base 3 and the second LED light mounting base 8 are respectively assembled to the first connecting base 402 and the second connecting base 702 through a threaded structure. After the beam splitter 5 is installed between the first condenser lens 4 and the second condenser lens 7 through the first condenser lens groove 401 and the second condenser lens groove 701, the bolts between the first condenser lens 4 and the second condenser lens 7 are tightened. Then, the first condenser lens 4 and the microscope connecting base 6 are respectively bolted to the top cover 2. The light source is connected to the outside through the connecting hole 201. The base 9 is assembled to the bottom of the top cover 2 by bolts. The automatic light source controller is connected to the LED lights through the power outlet 203, which can control the lighting arbitrarily, and can provide single lighting or simultaneous lighting. After the multi-purpose automatic light source body 1 is assembled onto the microscope through the microscope connecting base 6, the optical lenses are installed into the second connecting base 702 through the mounting slot 202 and the snap-fit ​​positioning slot 703, which can realize different functions and complete a series of tasks.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
