Put.
Background technology
Light microscope is the optical instrument that small items can be amplified or amplify the fine fraction of object, using wide
General, various researchs, teaching, generation practice can be used.Under many circumstances, one is designed superior microscope not necessarily
Obtain good image quality.It is good that its reason is typically the non-adjustment of light source, prevents sample from obtaining sufficiently illumination institute extremely.It is micro-
The optimal illumination condition of mirror sample should be become clear, free from glare and visual field illumination is uniform.Microscopical illumination according to
Bright beam pattern, can be divided into transmission-type illumination and fall to penetrating formula two major classes of illumination.Most biomicroscopes belong to transmission-type photograph
It is bright, but transmission-type illumination microscope is only applicable to transparent or semitransparent tested object, is not suitable for nontransparent tested object；
Fall to penetrating formula illumination microscope and be then applied to nontransparent tested object, light source comes from above, also known as reflective illumination, but in reality
The not enough situation of illuminance often occurs in application process, while possess transmission illuminator to have to fall to penetrating lighting device again
Often price is sufficiently expensive for advanced microscope.Therefore the transmission-type of just putting for frequently encountering single lower light source illuminates microscope light source deficiency,
There is no the situation of upper light source；Also single light source can be run into and falls to penetrating the not enough situation of formula illumination microscope illumination.It how to be light source deficiency
Microscope provide brightness rationally, obtain conveniently, it is with low cost, safe and reliable it is controllable section light source equipment be have to be solved
Problem.
The content of the invention
In view of this, the purpose of this utility model is to provide a kind of additional annular light source device of micro objective, by ring
Shape luminescent device is socketed on the micro objective of the additional light source of palpus, carries out light intensity regulating, produces appropriate light to be irradiated to tested
On object, and luminescent device has, and uniformity is luminous, uniformity colour temperature, and good condenser performance, overcomes practical application
During microscope light source luminance shortage problem, can be able to be single light source just to put the transmission-type illumination microscope upper light source of addition
Fall to penetrating formula microscope and transillumination supplement light source is provided.Make microscope while having light source for transmission illumination and epi-illumination light source,
Microscope multiple light courcess intensity adjustment is more convenient, and observes performance boost.
To reach above-mentioned purpose, the utility model provides following technical scheme：A kind of additional annular light source of micro objective
Device, including annular luminous circuit board, luminescent device and circuit controller, the luminescent device have several, are evenly spaced in
On the one side of annular luminous circuit board, described circuit controller one end passes through control signal plug and annular luminous circuit board phase
Even.
Further, it is uniform on the housing also including the housing being sleeved on outside annular luminous circuit board and luminescent device
Several locking jackscrews are distributed with.
Further, the housing is including outer cover and is arranged on outer cover end and the cover plate corresponding with luminescent device,
The cover plate is transparent PVC or PMMA or ABS materials.
Further, the circuit controller other end is connected with plug by power connector.
Further, the luminescent device uniform annular array on annular luminous circuit board.
Further, the luminescent device is light emitting diode.
The beneficial effects of the utility model are：It is present apparatus design advantages of simple, with low cost, small volume, lightweight, easy
Dismounting, light-source brightness adjustable range is big and can carry out infinitely fine control, uniform in light emission；Halogen bulb is replaced to shine with LED illumination light source
Mingguang City source, can avoid halogen bulb from scalding personnel, the shortcoming of short life.Can be arranged on and just put on biology microscope endoscope objective lenses, to close
Suitable brightness provides additional illumination, solves the problems, such as to observe transparency not sample high when brightness it is inadequate；Also can be arranged on and just put metallographic
Light filling is carried out to sample surfaces on micro objective；Can act also as falling to penetrating supplement light during formula illumination inverted microscope illumination deficiency
Source, is more convenient microscope multiple light courcess intensity adjustment, so as to lift its observation performance, has important to improving microscopic quality
Meaning.Can be widely applied to the fields such as biology, medical science, industry.
