Light source lighting circuit on stereomicroscope

Abstract

The invention provides a light source lamp circuit on a stereomicroscope, comprising a fixed component and a slide component which are opposite; wherein the slide component comprises an object lens and an observation device. The invention is characterized in that the fixed component is formed by two independent ring-shaped conducting rails, the two ring-shaped conducting rails are respectively connected with a circuit board connected with the cathode and the anode of a power source; two spring thimbles and a plurality of lamp sets are arranged in the sliding component, the two spring thimbles are respectively connected with the cathode and the anode of an LED; when the slide component is arranged in the fixed component, the two spring thimbles are respectively contacted with the conducting rails for conduction, thus being convenient for a user to use the stereomicroscope at any angle; the light source can freely rotate along with main body without being restricted by a connecting wire, thus providing the main body with clear visual field; and if the LED is used as the lamp set, illuminating effect of the lamp set is improved.

Description

technical field [0001] The invention relates to a light source lighting circuit on a stereo microscope. Background technique [0002] Illumination sources for stereo microscopes include natural light and artificial light. Natural light is not bright enough to observe the object after imaging through the microscope, which is limited in use. Therefore, microscopes generally require additional lighting. The illumination methods of stereo microscopes usually include transmitted illumination (lower light source) and reflective illumination (upper light source). The lower light source is located in the base of the microscope and is mainly used for observing slices, grid plates, resolution plates, etc. Due to the directness of the upper lighting, it not only increases the brightness but also increases the viewing angle, so the use of the upper light source lighting has a great advantage. The upper light source lighting has been widely used, but the position of the upper light so...

Problems solved by technology

In these situations, when using the upper light source for lighting, it needs to be directly connected to the luminous body on the main body through the wire connected to the power supply, which often causes the wire to be exposed, which makes it very inconvenient to disassemble the main body and the base.

[0004] Of course, in the lighting of the upper light source, there are also power wires connected to the light source built inside the body, and whether the power wire is inside or outside the body, since the light source and power wire belong to the traditional two-point and one-line fixed connection method, the rotation of the light source is inevitable. Limited by the wrapping of the wire connections, the light source cannot freely rotate with the subject and therefore cannot provide a clear field of view in the direction of subject rotation
