Description

Technical Field

[0001] This utility model relates to a light source structure for a microscope, and more particularly to a lower annular light source structure for a microscope, belonging to the field of microscope technology. Background Technology

[0002] When illuminating an object using a microscope, the light source is generally directed upwards or downwards; this is especially true for stereomicroscopes, which are visual instruments that produce an upright, three-dimensional image. Objects can be observed directly under the microscope lens without special sample preparation, producing a three-dimensional image that allows for direct viewing and high efficiency. However, since the light source is usually positioned below the object, there is a lack of direct illumination to the sides, making it difficult to observe the deep structures of complex objects. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing ring light source structures in stereomicroscopes, which lack side light sources and result in unclear observation of the deep structure of complex objects. This invention provides a lower ring light source structure for a microscope that provides both lower and side light sources for objects on the stage, enabling clear observation of the deep structure of complex objects.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a lower ring light source structure for a microscope, the microscope including a microscope body, an objective lens, a base plate and a bottom plane light source; a glass stage is provided above the base plate, the bottom plane light source is provided at the bottom of the base plate, and a central hole A is provided on the base plate;

[0005] It also includes a lower ring light source structure; the lower ring light source structure is located between the glass stage and the bottom plane light source; the lower ring light source structure includes a ring-shaped metal fixing plate, a central hole B, a light guide plate, LED patch lights, a circuit board, and a housing. The ring-shaped metal fixing plate protrudes upwards around its periphery, and the upper end of the periphery of the ring-shaped metal fixing plate is fixedly connected to the base plate. The central hole B, light guide plate, LED patch lights, circuit board, and housing are arranged sequentially from the center to the periphery between the base plate and the ring-shaped metal fixing plate; the ring-shaped metal fixing plate serves both a fixing function and a heat dissipation function.

[0006] The inner surface of the light guide plate is a cone-shaped surface with an upward sloping angle; the central hole B is a conical hole; the upper end of the conical hole matches the central hole A on the base plate; the angle between the cone-shaped surface and the horizontal direction is 90 to 135°.

[0007] The lower ring light source structure and the bottom plane light source form a double-layer lighting source;

[0008] The lower ring light source structure also includes a brightness adjustment knob, an illumination mode adjustment knob, and an illumination position adjustment knob; a knob fixing plate is provided on the upper front of the base plate, and the brightness adjustment knob, illumination mode adjustment knob, and illumination position adjustment knob are arranged on the knob fixing plate from left to right.

[0009] The lighting modes include full-ring lighting, 1 / 2-ring lighting, and 1 / 4-ring lighting, which are adjusted using a lighting mode adjustment knob. In 1 / 2-ring and 1 / 4-ring lighting modes, the position of the illuminated light is adjusted using a lighting position adjustment knob.

[0010] The inner surface of the light guide plate is a cone-shaped surface that slopes upwards, with an angle of 112° between it and the horizontal direction.
