Description
Technical field
The adjustable no umbra stereomicroscope illuminator of condensing angle of the present invention is related to a kind of light source intensity of illumination and condensing angle
It can adjust, be observed the stereomicroscope illuminator that body surface irradiates without umbra.
Background technology
For stereomicroscope image quality with closely related with irradiation source performance, stereomicroscope has natural light with irradiation source
With two kinds of electric light source, matched somebody with somebody using natural light and shone by various conditionalities, it is difficult to high quality micro-image is obtained, it is therefore, stereoscopic
Microscope is illuminated using electric light source more.Electric light source can be divided into thermal light source and cold light source again, general thermal light source using incandescent lamp,
Tungsten lamp or halogen tungsten lamp etc., because thermal light source is that thermal excitation lights, therefore using being restricted in vivo observation.High brightness lights
Almost empty calory produces for LED lighting efficiency high, particularly luminescence process, is especially suitable for the illumination of live body microscopic observation and uses.With
Microscope circular lamp made of high brightness LED, is widely applied.But due to the directive property of light emitting diode
Relatively strong, general lighting angle is less than 45 °, and when object distance is less than certain value, the dark space of no light occurs in microscopic fields of view center, shows
Micro mirror can not blur-free imaging.
The content of the invention
In order to solve the above problems, the present invention devises a kind of adjustable no umbra stereomicroscope illuminator of condensing angle,
Not only intensity of illumination can adjust the illuminator, and condensing angle is equally adjustable, while be advantageous to eliminate central dark space.
The object of the present invention is achieved like this：
No umbra stereomicroscope illuminator that condensing angle is adjustable, by upper light bulb, lower light bulb, supporting plate, soft light sheet, LED light
Source piece composition；
The upper light bulb sets gradually microscope fixed part, main part, male thread portion and suspension ring from top to bottom
Part；The microscope fixed part, which is screwed, to be connected on microscope lens barrel, the male thread portion and lower light bulb
Threaded connection；The top of the eye portion rotating shaft connection LED light source piece；
The lower light bulb sets gradually female thread portion and chamber portion from top to bottom；The female thread portion and external screw thread
Partial threads are connected, and supporting plate is provided with the chamber portion；
The splint upper surface is provided with dovetail groove, and the lower section of LED light source piece is slided in dovetail groove；Supporting plate is under
Light bulb in vertical direction without translation, relative to upper light bulb in the horizontal direction without rotation；
The soft light sheet is arranged at the bottom of lower light bulb；
The LED light source piece includes connecting plate and is arranged on the LED of connecting plate bottom, the top rotating shaft of the connecting plate
Eye portion is connected, the lower section of connecting plate is slided in dovetail groove.
The above-mentioned adjustable no umbra stereomicroscope illuminator of condensing angle, the supporting plate top contact chamber portion top,
Bottom contact soft light sheet top, all portions coordinate with chamber portion gap.
Beneficial effect：
Firstth, using LED illumination, LED brightness can be changed by changing electric current, therefore light source light can be realized according to strong
Spend adjustable function；
Secondth, because upper light bulb is threadedly coupled with lower light bulb, therefore by screwing lower light bulb, it is relative that lower light bulb can be adjusted
In the distance of upper light bulb；Due to being provided with relative to lower light bulb in supporting plate of the vertical direction without translation, and the upper lamp of rotating shaft connection
Cylinder and the LED light source piece slided in support class surface dovetail groove, therefore when screwing lower light bulb, LED light source piece can be changed
Angle, the effect of adjustment condensing angle is realized, is advantageous to eliminate central dark space；
3rd, due to setting the soft light sheet with diffusing transmission effect, therefore light beam can be changed through the angle after soft light sheet
Degree, weakens the directive property of beam Propagation, and then be advantageous to eliminate central dark space.
