Background

The microscope is composed of one or more lens combinations and is mainly used for magnifying tiny objects to enable the tiny objects to become instruments which can be observed by naked eyes of people. Among them, the biological microscope is widely used in examination and analysis of samples such as blood, urine, tissue slices, etc. as a common device for clinical examination.

In order to make the object image magnified by the lens clearly and easily recognized, a reflector is required to reflect light or a light source is arranged to emit light to an objective table to illuminate a specimen on the objective table. Because the adjustment process of the light source is simpler and the light is more stable, the existing microscope mostly adopts a structure for arranging the light source.

The existing biological microscope light source mostly adopts a halogen lamp, because the halogen lamp emits light in a filament form, the situation of uneven illumination intensity is easily caused by adopting critical illumination, the structure of Kohler illumination is more complex, and the simplification and miniaturization of the microscope structure are difficult to realize; therefore, in practical use, the halogen lamp often uses a frosted or atomized lens to condense light.

Using a halogen lamp as a microscope light source has the following problems:

firstly, the brightness is attenuated quickly, and for human eye observation or a microscope adopting image acquisition equipment with fixed exposure time, the contrast of an image is reduced due to the darkening of background light, so that the observation and the identification are not facilitated;

secondly, the service life is short, the average service life of the halogen lamp is only hundreds of hours, and the bulb needs to be replaced frequently for a frequently used microscope;

thirdly, the photoelectric conversion efficiency is low, so that the thermal efficiency is high, the temperature of the outer shell of the light source is high after continuous operation for more than several hours, and the risk of scalding operation or maintenance personnel exists;

and fourthly, the application range is limited, and the brightness after the halogen lamp is homogenized by the frosted or atomized lens is greatly limited due to low photoelectric conversion efficiency of the halogen lamp, so that the halogen lamp is not suitable for a high-power objective lens and scanning imaging of the high-power objective lens.
