Description
Technical field
The utility model relates to stereomicroscope auxiliary lamp source technical field, specifically light source on a kind of stereomicroscope.
Background technology
Stereomicroscope is widely used in the middle of daily production, teaching and scientific research field, in the teaching and scientific research particularly in plant protection, is usually used in observing the less insect of the bodily form or plant specimen.The lighting system of stereomicroscope comprises transmission-type illumination (lower light source) and reflective illumination (upper light source).Wherein, the lighting system of upper light source mainly contains following 4 kinds:
1. light source is arranged on the side of object lens bracket, moves up and down with object lens.Its shortcoming is that sample deviates from light source side illumination not, and also can form shade at objective table, impact is observed or taken pictures, and can shift to side away from illumination center during sample with object lens.
2. an additional circular lamp does light source.Be generally at present and be fixed by screws in micro objective lower end, move up and down with object lens.Its shortcoming is the zoom operation affecting object lens, and electric wire is scattered in around mirror, causes working environment in disorder, also easily loses after pulling down.
3. an additional independent lighting source, as hard tube optical fiber, general independent illumination device (similar with desk lamp).Be placed on mirror side, do not move up and down with object lens.Its shortcoming has shade or easily loses.
4. be built on object lens, as coaxial-illuminating, vertical illumination etc.Its shortcoming is complex structure, cost is high and change difficulty.And with the 1st, 2 kind of mode be the same, all move up and down with object lens, when object lens move, light source also with on move and away from the sample on objective table, light weakened.
Utility model content
The technical problems to be solved in the utility model is, for the deficiency that prior art exists, provides that a kind of structure is simple, light source on stereomicroscope that the height of installing and removing easy, easy to use, light source and brightness can arbitrarily regulate.
The utility model solves the problems of the technologies described above taked technical scheme: light source on a kind of stereomicroscope, comprise the potentiometer of LED circular lamp source, Connection Block, deformable connecting link, holder and belt switch, LED circular lamp source is connected with deformable connecting link by Connection Block, deformable connecting link is connected with holder, the lifting support that fixed seating is connected on stereomicroscope is positioned at below object lens bracket, holder side is provided with by-pass cock knob and fixed screw, by the installation and removal regulating the degree of tightness of fixed screw can realize holder; Potentiometer one end of belt switch is connected with one end, LED circular lamp source, and the potentiometer other end of belt switch is connected with positive source; The LED circular lamp source other end is connected with power cathode; The potentiometer clearance fit of by-pass cock knob and belt switch, can regulate switch and the brightness in LED circular lamp source.
Described LED circular lamp source comprises annular lamp holder and is arranged on several LED on annular lamp holder.
The utility model possesses following advantage:
(1) adopt LED circular lamp source, sample to be seen can not form shade;
(2) be fixed on below object lens bracket by holder, the zoom operation of object lens can not be affected, also can not with object lens move up and down and mobile, the stable of illumination on sample can be ensured, be beneficial to and observe and take pictures;
(3) deformable connecting link can random variation, and the height of light source can arbitrarily be regulated;
(4) the potentiometer clearance fit of by-pass cock knob and belt switch, switch and the brightness in LED circular lamp source can be regulated simultaneously, during use by brightness regulation to then powered-down connecting circuit automatically after minimum, when can avoid switch and brightness regulation that button is set respectively, operating personnel not by brightness regulation to minimum with regard to powered-down, be communicated with power supply when reusing and LED may be caused to damage or shorten the situation in LED serviceable life.
(5) disassemble from stereoscope by regulating the degree of tightness of fixed screw can be arranged on by holder like a cork on stereoscope or when damaging; Do not need to pull down after finishing using normally at every turn, thus can not lose.
(6) the utility model structure is simple, and cost is lower, and practicality is good.

Reference numeral is: 1.LED circular lamp source, 2. Connection Block, 3. deformable connecting link, 4. by-pass cock knob, 5. holder, 6. fixed screw, the 7. lifting support of stereomicroscope, 8. power lead, the 9. potentiometer of belt switch.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
As shown in Figure 1-Figure 3, light source on a kind of stereomicroscope, comprise LED circular lamp source 1, Connection Block 2, deformable connecting link 3, holder 5 and belt switch potentiometer 9, LED circular lamp source 1 comprise annular lamp holder 101 and be arranged on two circle LED 102 on annular lamp holder.LED circular lamp source 1 is connected with deformable connecting link 3 by Connection Block 2, deformable connecting link 3 is connected with holder 5, the lifting support 7 that holder 5 is socketed in stereomicroscope is positioned at below object lens bracket, holder 5 side is provided with by-pass cock knob 4 and fixed screw 6, by the installation and removal regulating the degree of tightness of fixed screw 6 can realize holder 5; Potentiometer 9 one end of belt switch is connected with one end, LED circular lamp source 1 with by wire, and potentiometer 9 other end of belt switch is connected with positive source by power lead 8; LED circular lamp source 1 other end is connected with power cathode by power lead 8; Can in parallel or series connection by wire between LED 102; By-pass cock knob 4 and potentiometer 9 clearance fit of belt switch, can regulate switch and the brightness in LED circular lamp source 1 simultaneously.
