Problems solved by technology

However, at present, microscopes with light sources usually only use non-adjustable light sources, so there are some limitations or deficiencies: First, the brightness of the illumination cannot be adjusted, which cannot well meet different use requirements; second, the color temperature of the illumination cannot be adjusted, and users cannot The characteristics of the specimen, choose the appropriate color temperature of the light source to obtain the best observation effect through the microscope

Embodiment 1）

[0045] In this embodiment, when describing the orientation, the figure 1 The left and right directions in the description of the front and rear, to figure 1 The direction facing is the right side when describing, to deviate from figure 1 The direction of the description is to the left, with figure 1 The up and down directions in are the up and down directions when describing.

[0046] See figure 1 , the microscope with adjustable illumination color temperature and brightness of this embodiment consists of a frame assembly 1, a collecting lens assembly 2, an object stage assembly 3, an eyepiece assembly 4, a converter 5, an objective lens assembly 6, an adjustment knob assembly 7 and an illumination adjustment assembly. The optical device 8 is composed.

[0047] See figure 2 , the frame assembly 1 is used to support various components of the microscope. The mirror frame assembly 1 is composed of a mirror frame 11 , a rear cover 12 and a bottom plate 13 .

[0048] The mi...

Embodiment 2）

[0076] See Figure 8 , Figure 9 with Figure 10 , the rest of this embodiment is the same as Embodiment 1, the difference is that: the number of light emitting diodes 81-1 of the light emitting diode module 81 of the aforementioned lighting dimming device 8 is 3, and a color temperature of 2700K is added. Light-emitting diode D23; At the same time, a third indicator light, that is, light-emitting diode D15, is correspondingly added on the lighting adjustment panel 82 of the lighting adjustment device 8, and the lighting adjustment panel 82 is correspondingly marked as 2700K-2; the lighting control circuit of the lighting adjustment device 8 In the lighting control circuit 86-1 on the board 86, a resistor R35 matching the third selection indicator light (that is, the light-emitting diode D15) is added, and a second D / A of the same type as the D / A converter U4 is also added. Converter U5, and the corresponding resistor R38 connected between the first output terminal OUTA (pin...

Abstract

The invention provides a microscope with adjustable illuminating color temperature and brightness. The microscope is characterized in that a condenser component and an illuminating and dimming device are arranged on a mirror bracket component of the microscope, wherein the illuminating and dimming device comprises a light-emitting diode (LED) module, an illumination adjusting panel, an illumination control circuit board, a power conversion component and a power socket; an illumination control circuit is arranged on the illumination control circuit board; and the condenser component is arranged above the LED module. When the microscope is used, light emitted from the LED module is mixed and provides illumination for an observed specimen through the condenser; and by operating the illumination adjusting panel, the illumination control circuit responds to operation of the illumination adjusting panel, so that current flowing through the LED is controlled, and the brightness or color temperature of the illuminating mixed light is correspondingly adjusted. The color temperature or brightness of the mixed light irradiating the observed specimen can be conveniently adjusted, so that the microscope can adapt to different service environments, different service requirements are met, and a good observation effect is achieved.

Description

technical field [0001] The present invention relates to microscopes, and more particularly to microscopes with light source systems. Background technique [0002] The microscope is mainly composed of two parts: mechanical device and optical system. The mechanical device part is mainly composed of mirror frame, converter, stage, focusing device, etc.; the optical system is mainly composed of objective lens group, eyepiece and so on. Traditional microscopes do not have a light source system, and most of them use reflectors attached to the frame to collect light. Newer microscopes usually use a light source system. The light source system is usually installed in the frame of the microscope. The light source is turned on and off by a button switch. The light source system is equipped with a condenser accordingly, and the light source system converges the light emitted by the light source into The cone of light illuminates the specimen for enhanced illumination and observation....
