Description

Technical Field

[0001] This utility model relates to the field of fluorescence microscope illumination technology, and specifically to an illumination device for a fluorescence microscope. Background Technology

[0002] With the development of laser technology, more and more modern microscopy techniques have rapidly emerged. Fluorescence microscopy is increasingly widely used in biomedical research, and its technological development has been rapid, making it a popular research area. Fluorescence microscopy can obtain high-resolution images by exciting the fluorescence or nonlinear optical phenomena of the object under test using a laser light source. Furthermore, dichroic mirrors, as important components in fluorescence microscopy, can reflect certain colors of light and transmit other colors of light according to their wavelength.

[0003] Existing fluorescence microscope illumination devices (application number 202121396508.X, a multispectral LED lamp illumination device for fluorescence microscopes) require manual adjustment of the brightness, height, and tilt angle of the laser mercury lamp used for illumination. After adjustment, the data of the mercury lamp cannot be recorded intuitively, and the illumination device cannot be returned to the initial position in a timely manner, thus affecting the efficiency and accuracy of the fluorescence microscope. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an illumination device for a fluorescence microscope to solve the technical problems of existing fluorescence microscope illumination devices, where the brightness, height and tilt angle of the mercury lamp need to be manually adjusted, the data of the mercury lamp cannot be recorded intuitively after adjustment, and the illumination device cannot be returned to the initial position in time, thus affecting the efficiency and accuracy of the fluorescence microscope.

[0005] According to the technical solution provided in the embodiments of this application, an illumination device for a fluorescence microscope includes an illumination box, on the side of which are installed a light brightness adjustment knob, a tilt angle adjustment knob, and a vertical direction adjustment knob. Corresponding adjustment mechanisms are installed on the light brightness adjustment knob, the tilt angle adjustment knob, and the vertical direction adjustment knob for electric adjustment of the light inside the illumination box.

[0006] The adjustment mechanism includes a rotation drive, a drive gear, and a driven gear. The driven gear is mounted on the adjustment column and meshes with the drive gear. The drive gear is fixedly connected to the output end of the rotation drive, thereby causing the rotation drive to drive the adjustment column to rotate.

[0007] The adjusting column has a movable groove inside, and the adjusting rod is movably installed in the movable groove. The end of the movable groove has a locking groove, and corresponding positioning grooves are provided on both sides of the locking groove. The end of the adjusting rod is engaged in the locking groove, and a corresponding positioning block is provided in the middle of the adjusting rod. This allows the adjusting rod to be moved, and the two positioning blocks to be engaged in the corresponding positioning grooves, so that the adjusting rod is positioned and connected to the adjusting column, allowing the adjusting column to be manually adjusted.

[0008] Furthermore, each of the adjustment columns is equipped with a corresponding light brightness adjustment knob, tilt angle adjustment knob, and vertical direction adjustment knob at its front end.

[0009] Furthermore, a limiting plate is installed on the adjusting rod, and the diameter of the limiting plate is adapted to the inner diameter of the moving groove.

[0010] Furthermore, an elastic element is also installed inside the movable groove. The elastic element is sleeved on the outside of the adjusting rod and abuts against the limiting plate.

[0011] Furthermore, the outside of the lighting box is also provided with a power connection port and a control connection port, and the control connection port is electrically connected to the connection terminal on the control panel via a connection cable.

[0012] Furthermore, the control panel is movably mounted on the side of the fluorescence microscope body.

[0013] Furthermore, the light brightness adjustment knob, the tilt angle adjustment knob, and the vertical direction adjustment knob are spaced apart from top to bottom along the vertical direction.

[0014] Furthermore, the elastic element is a metal spring.

[0015] Furthermore, a mercury lamp is installed inside the lighting box, and the mercury lamp is electrically connected to the rotation drive on the light brightness adjustment knob for adjusting the brightness of the mercury lamp.

[0016] Furthermore, a beam splitter is also installed inside the lighting box. The beam splitter is connected to the tilt angle adjustment knob and the vertical direction adjustment knob, so that by rotating the tilt angle adjustment knob and the vertical direction adjustment knob, the height and angle of the beam splitter can be adjusted.

[0017] In summary, the beneficial effects of this application are as follows:

[0018] 1. By installing corresponding adjustment mechanisms inside the light brightness adjustment knob, beam splitter tilt angle adjustment knob, and vertical direction adjustment knob on the lighting box of the lighting device, each adjustment mechanism is electrically connected to the control panel. This allows the operator to adjust the light brightness, beam splitter tilt angle, and vertical direction of the lighting device through the control panel, making the lighting device more convenient and improving the light adjustment efficiency of the lighting device for the fluorescence microscope.

[0019] Second, by setting up an adjustment mechanism, the rotation drive component on the adjustment mechanism drives the fixedly connected drive gear to rotate, which in turn drives the meshing driven gear to rotate, causing the adjustment column with the driven gear to rotate, thereby adjusting the corresponding light brightness, beam splitter angle and height. After observation, the control panel can be used to return each light brightness adjustment knob, beam splitter angle and height to their initial positions, without affecting the normal use of the fluorescence microscope illumination device.

[0020] Third, by setting a movable groove inside the adjustment column, the adjustment rods on each adjustment knob are movably installed in the movable groove, so that the push adjustment rod moves inward along the movable groove, thereby causing the positioning block on the adjustment rod to engage with the positioning groove on the adjustment column, thus turning the adjustment knob into manual adjustment mode. After use, the compressed elastic metal spring drives the adjustment rod to return to its original position, without affecting the normal use of the adjustment mechanism, thereby improving the illumination efficiency and illumination quality of the illumination device for the fluorescence microscope.

[0028] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] An illumination device for a fluorescence microscope, the structure of which is as follows: Figures 1-5As shown, the system includes an illumination box 100, on the side of which are mounted a light brightness adjustment knob 200, a tilt angle adjustment knob 300, and a vertical direction adjustment knob 400. Corresponding adjustment mechanisms 600 are mounted on adjustment columns 500 connected to the light brightness adjustment knob 200, tilt angle adjustment knob 300, and vertical direction adjustment knob 400, respectively. These mechanisms 600 automatically adjust the corresponding light brightness, the height of the spectroscope, and the tilt angle, thereby improving the illumination quality of the fluorescence microscope. The adjustment mechanism 600 includes a rotation drive 610, a driving gear 620, and a driven gear 630. The driven gear 630 is mounted on the adjusting column 500 and meshes with the driving gear 620. The driving gear 620 is fixedly connected to the output end of the rotation drive 610, thereby causing the rotation drive 610 to drive the fixedly connected driving gear 620 to rotate, which in turn drives the driven gear 630 meshing with the driving gear 620 to rotate. This causes the adjusting column 500, on which the driven gear 630 is mounted, to rotate, allowing the adjusting mechanism 600 to rotate and adjust the adjusting column 500, thereby adjusting the light dimming regulator and beam splitter connected to the adjusting column 500. The adjusting column 500 has a moving groove 501 inside, and the adjusting rod 210 is movable. The adjusting rod 210 is mounted in the movable slot 501, and the end of the movable slot 501 is provided with a slot 502. Corresponding positioning slots 503 are provided on both sides of the slot 502. The end of the adjusting rod 210 is engaged in the slot 502, and a corresponding positioning block 230 is provided in the middle of the adjusting rod 210. This allows the adjusting rod 210 to move inward, thereby positioning and engaging the two positioning blocks 230 on the adjusting rod 210 in the corresponding positioning slots 503 on the adjusting column 500. This allows the adjusting rod 210 to be positioned and connected to the adjusting column 500, so that the adjusting column 500 can be manually adjusted, thereby adjusting the brightness of the light, the height and angle of the beam splitter on the lighting device.

[0031] As a preferred embodiment, please refer to Figure 4 and Figure 5 Each adjustment column 500 has a corresponding adjustment rod 210 installed at its front end. Each adjustment rod 210 is connected to a corresponding brightness adjustment knob 200, tilt angle adjustment knob 300, and vertical direction adjustment knob 400. When manually adjusting the brightness of the lighting and the height and angle of the beam splitter, the adjustment rod 210 is first pushed inward along the horizontal direction, so that the positioning block 230 on the adjustment rod 210 is engaged in the corresponding positioning groove 503 on the adjustment column 500. Then, the adjustment knobs are rotated to adjust the brightness of the lighting and the height and angle of the beam splitter, thereby improving the versatility of the lighting device.

[0032] As a preferred embodiment, please refer to Figure 4 and Figure 5A limiting plate 220 is installed on the adjusting rod 210. The diameter of the limiting plate 220 is compatible with the inner diameter of the moving groove 501. An elastic element 504 is also installed in the moving groove 501. The elastic element 504 is a metal spring and is sleeved on the outside of the adjusting rod 210. The elastic element 504 abuts against the limiting plate 220 so that when the lighting adjustment mode is switched to manual adjustment, the adjusting rod 210 is pushed to move inward along the moving groove 501 on the adjusting column 500, thereby causing the limiting plate 220 to compress the metal spring of the elastic element 504. When the manual adjustment is completed, the compressed metal spring of the elastic element 504 returns to its original position, thereby causing the adjusting rod 210 with the limiting plate 220 installed to return to its original position.

[0033] As a preferred embodiment, please refer to Figure 2 and Figure 3 The outside of the lighting box 100 is also provided with a power connection port 110 and a control connection port 120. The control connection port 120 is electrically connected to the connection terminal 710 on the control panel 700 via a connection cable. The control panel 700 is movably installed on the side of the fluorescence microscope body 800, so that the operator can adjust the light in the lighting box 100 in a timely manner when using the fluorescence microscope through the control panel 700 installed on the side of the fluorescence microscope body 800. At the same time, the light brightness adjustment knob 200, the tilt angle adjustment knob 300, and the vertical direction adjustment knob 400 are arranged vertically from top to bottom at intervals, so that the operator can adjust the brightness of the lighting on the lighting device, the height of the spectroscope, and the tilt angle in a timely manner, so that the fluorescence microscope can be used in different lighting environments.

[0034] As a preferred embodiment, please refer to Figure 3 The lighting box 100 also contains a mercury lamp, which is electrically connected to the rotation drive 610 on the lamp brightness adjustment knob 200, thereby adjusting the brightness of the mercury lamp. The lighting box 100 also contains a beam splitter, which is connected to the tilt angle adjustment knob 300 and the vertical direction adjustment knob 400, so that by rotating the tilt angle adjustment knob 300 and the vertical direction adjustment knob 400, the height and angle of the beam splitter can be adjusted.

[0035] The working principle of the illumination device for a fluorescence microscope of this invention is as follows:

[0036] When the illumination device on the fluorescence microscope provides illumination for microscopic observation, the operator attaches the illumination box 100 of the illumination device to the rear end of the fluorescence microscope body 800, connects the connecting cable to the control connection port 120 on the illumination box 100 and the connection terminal 710 on the control panel 700, and plugs the power supply cable into the power connection port to turn on the illumination. During the observation of different biological cells, the operator controls each adjustment mechanism 600 through the control panel 700, causing the rotation drive 610 on each adjustment mechanism 600 to start under the control of the controller. This causes the rotation drive 610 to drive the drive gear 620 to rotate, which in turn causes the driven gear 630 meshing with the drive gear 620 to rotate. This, in turn, causes the adjustment column 500, which is equipped with the driven gear 630, to rotate, causing the mercury lamp controller in the illumination box 100 connected to each adjustment column 500 to rotate, thereby adjusting the brightness of the light in the illumination box 100. The adjustment column 500 connected to the beam splitter adjusts its beam splitting height and tilt, thus allowing the operator to... The brightness, tilt angle, and vertical height of the illumination device can be adjusted via the control panel 700, making the illumination device more convenient and improving its efficiency in adjusting the fluorescence microscope's light. After observation, the brightness adjustment knobs 200, the tilt angle, and the height of the beam splitter can be returned to their initial positions via the control panel 700, without affecting the normal use of the fluorescence microscope's illumination device. A moving groove 501 is provided in the adjustment column 500, allowing the adjustment rods 210 on each adjustment knob to be movably installed in the moving groove 501. Pushing the adjustment rods 210 inward along the moving groove 501 causes the positioning block 230 on the adjustment rod 210 to engage with the positioning groove 503 on the adjustment column 500, thus switching the adjustment knobs to manual adjustment mode. After use, the compressed elastic element 504 metal spring drives the adjustment rods 210 to return to their original position, without affecting the normal use of the adjustment mechanism 600. This allows the illumination device to be used in both manual and automatic adjustment modes, thereby improving the illumination efficiency and quality of the fluorescence microscope.

[0037] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept.
