Description
Technical field
The utility model relates to a kind of illumination of going up of stereomicroscope, specially refers to a kind of microlamp group light source illuminating apparatus.
Background technology
In traditional microscope, stereomicroscope is a kind of relief visual instrument of erect image that has, and operating distance is very long, and field number is very big, and depth of focus is very long, often is used to detect a precision component of industrial circle, perhaps may be plant or toy such as small insect.
Stereomicroscope comprises: dispose object lens main body, dispose objective table base, dispose the focus adjusting mechanism of carriage.Between the carriage of main body and focus adjusting mechanism is to be connected by a hole, main body is placed in the hole of carriage, and main body can be done 360 degree rotations in the hole of carriage, forward the working position of wanting to after, use a screw lock.This version can be convenient for changing different microscope bodies on same carriage, realize the modular design and the sale of product.
The lighting source of stereomicroscope has natural light, Halogen lamp LED, fluorescent light, optical fiber, lamp group etc.The colour temperature of natural light is to meet us most to observe requirement, but because its brightness of illumination is bright inadequately by observing object behind the microscope imaging, in use is restricted, and only in the microscope low-grade, that enlargement factor is low use is arranged.
The lighting system of stereomicroscope has transillumination (following light source) and reflective illumination (going up light source).Following light source is positioned at microscopical base, by direct or certain light path glass platen on the base or frosted glass platen is evenly illuminated, and the sample of observation is placed on the platen, is mainly used in to observe section, waffle slab, resolving power test target etc.
The mode of last illumination has following four kinds:
(1) go up the side that light source is installed in the focus adjusting mechanism bracket, sample is formed oblique illumination,-----its shortcoming is the situation that a side backlight has the complete or dark side of illumination with about the object lens, and influence is to the observation as a precision component side backlight.
(2) make an additional lighting source,, it is characterized in that, be fixed on the end of microscope body by dog screw, about object lens as circline, annular lamp group, optical fibre ring.By the screwed in place screw retention endways in the portion, and by unclamping dog screw to pull down-----its shortcoming from terminal part be to have influence on by rotating the main body object lens to realize becoming doubly microscopical change and doubly operate and influence microscopical overall appearance, and this lighting system is can load onto also to pull down, the electric wire of its power supply just will inevitably be scattered in microscopical around, cause and use microscopical working environment in disorder, after pulling down lighting accessory, also cause easily and lose.
(3) do an independent lighting accessory, as hard tube optical fiber, general independent luminaire (the entablement lamp ﹠ lantern seemingly), this luminaire is independent of outside the microscope, be not installed on the microscope, only be placed on the next door illumination, not moving-----its shortcoming with arbitrary parts on object lens or the microscope is that lighting accessory is lost easily and taken the space that the end user operates sample, hinders operation.
(4) be a kind of illumination that is built in the microscope body, as coaxial luminaire, vertical illuminator, this illumination needs the illumination path design of a complexity, is equipped with physical construction again, is a complexity, expensive illuminator.And the illumination hot spot of vertical illuminator is a certain size, when using little multiple, big visual field object lens, and the situation that will exist whole visual field to illuminate.Below all be that light source is positioned over outside the objective tube.
Even the illumination that has is built on the interior body of objective tube, when needing to rotate the object lens observation,, the limitation of its circuit of light sources observes because causing the microscope head to be difficult to rotate.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, cost is low, light source illuminating apparatus on the stereomicroscope of long service life, illumination efficiency height, high brightness, cold light source.
In order to realize above-mentioned illumination purpose, the utility model has been taked to be made up of the lamp group that (comprises two) more than two, two enclosed type strip conductors, two spring thimbles, the lamp group adopts bi-directional symmetrical to arrange or placed in the middle closely the arrangement is installed in the object lens cover, two spring thimbles link to each other with lamp group anode and cathode respectively, two annular strip conductors are connected with the cathode and anode of power supply respectively, corresponding with the cathode and anode of the strip conductor respectively contact of the anode and cathode of spring thimble.
Described lamp group place plane parallel is installed in the object lens cover in object lens cover below xsect.
Basic and the lens barrel parallel sidewalls of its plantation direction of described lamp group.
Described lamp group, the sample on the near normal lighting object stage.
Described annular strip conductor is installed in the carriage of focus adjusting mechanism.
Described two spring thimbles are installed in the side-lower of microscope body side by side.
Described power supply is on Microscope base, and the corresponding contact of negative electrode of annular strip conductor on the negative electrode of spring thimble and the carriage forms to connect and realizes the lamp group is powered.
Mutually insulated between described two annular strip conductors is isolated with insulating material with tray chamber.
Described annular strip conductor 10 is connected with electric wire 12 respectively, and electric wire 12 is through the inner chamber of carriages 4 interior bone, microscope frame 3, be connected on the anode and negative electrode of power circuit 11 of Microscope base 5 at last.
Described lamp group can be chosen as LED.
Advantage:
1, be fixedly mounted in the object lens cover, be integral with whole object lens are hood-shaped, what move up and down together goes up illumination, has changed with front light-source to be positioned over structure outside the object lens cover.
2, provide condition for main body angle rotation arbitrarily on focus adjusting mechanism. because the contact keeping corresponding with guide rail and contacting, thereby the same maintenance of luminophor lights, and is not easy to use the person like this from arbitrarily angled use microscope, and do not connect the winding of electric wire.
3, in addition, this structure is installed the circuit of the circuit of base and main body respectively because the lamp group is to be embedded in the main body in the object lens cover, when we dismantle main body and since the lamp group along with main body together.When main body from carriage dismounting or when installing, no longer be subjected to the restriction of electric wire, make the microscope dismounting convenient, and the outward appearance of complete machine is succinct.
4, very even to illuminated object illumination, can eliminate shade effectively.So just can reach traditional desired observing effect of annular light source with lower cost.
