Abstract
The utility model relates to a two-color lamp source magnifier, comprising a frame, a convex, a power supply, purple-light lamps and white-light lamps. The convex is arranged in the frame; the inner side of the frame is provided with a row of purple-light lamps; a white-light lamp bracket is embedded in the frame and internally provided with the white-light lamps; both the white-light lamps and the purple-light lamps are connected with the power supply which is arranged at the tail part of the frame. The two-color lamp source magnifier can be compatible with the irradiation of two kinds of light rays so as to be convenient for a gemstone appraiser to accurately appraise the entire gemstone by the irradiation of different light rays.
Description
Technical field
The utility model relates to the jewel evaluation apparatus, a kind of magnifying glass that jewel is identified that is used for of saying so exactly, and this magnifying glass can be used in differentiates diamond, the refraction situation of bullion under the different light rays effect, thinks that the evaluation of specialty provides foundation.
Background technology
Magnifying glass is the most basic outfit of jewel research, inclusion, birefringence ghost image and other details of using magnifying glass to can be used to observe jewel.The used magnifying glass of research jewel is different from common magnifying glass; The multiplying power of general magnifying glass is not enough, and image can cause crookedly at the picture frame edge, thereby can not be used for observing jewel.Jewel is less with the size of magnifying glass, and has used two convex lens, makes it after the precision design, higher enlargement ratio is arranged and do not have crooked image.Usually used jewel does not wait at 10x～22x with the multiplying power of magnifying glass, and jewel selects 10 times of persons best with the magnifying glass multiplying power, there is no need to be higher than this multiplying power; If very will observe more powerful details, that just have to use microscope.10 times of jewel magnifying glasses, size has only several centimeters sizes, is easy to carry, even allow the researcher not have under the situation of other precision instrument, also can do preliminary observation to jewel.
Yet above-mentioned magnifying glass, only be the refraction of natural daylight to be observed by jewel, the scope and the condition of observing are limited, tend to have influence on assessor's judged result, therefore, be necessary to design a kind of magnifying glass that multiple refraction method can be provided, be beneficial to jewel is comprehensively observed.
The utility model content
Based on this, the utility model provides a kind of bi-colour light source magnifying glass, and this magnifying glass can provide two kinds of light to carry out the judgement that jewel is identified, is convenient to the assessor and exactly jewel is assessed.
Another purpose of the present utility model is to provide a kind of bi-colour light source magnifying glass, and this magnifying glass is simple, volume is little, is easy to carry.
The utility model is achieved in that
A kind of bi-colour light source magnifying glass, include picture frame, convex lens, it is characterized in that this magnifying glass also includes power supply, purple lamp and white lamps gauge tap, described convex lens are arranged in the picture frame, and the inboard of picture frame is provided with a row purple lamp, also is embedded with white lamp bracket in the picture frame, be provided with white lamps in the white lamp bracket, white lamps all is connected with power supply with the purple lamp, and the afterbody of power supply setting and picture frame is connected with purple etc. with white lamps by gauge tap.
Described picture frame, it has a hole, is used to be provided with convex lens, and a depressed part is used to be provided with power supply.
Above-mentioned picture frame, the top of its depressed part has battery cover, and battery cover is movably connected on the picture frame, is convenient for changing battery.
Described power supply, it is a battery.
Described gauge tap is arranged at the side of picture frame, so that the switch of white lamps and purple lamp is controlled.
Described white lamps, its position can with the location swap of purple lamp.
Described white lamps and purple etc. are the LED lamp, all have more than two, are uniformly distributed in the edge that picture frame is provided with the hole of convex lens.
Described bi-colour light source magnifying glass, its outside also is provided with mirror holder, and in order to protecting this magnifying glass, mirror holder is movably connected on the afterbody of picture frame by axle, and promptly the afterbody of picture frame has an axis hole, and axle passes wherein, and the two ends cover of axle ties up on the mirror holder.
Above-mentioned mirror holder is two structure up and down, and the edge of this two chip architecture couples together by the mirror holder limit, with can interlock, covers convex lens simultaneously, and convex lens are protected.
The utility model adopts above-mentioned structure, makes magnifying glass can realize the irradiation of two kinds of light sources, is convenient to the radiation of jewel assessor by different light rays, and jewel is carried out comprehensively, identifies exactly.
And this magnifying glass is just assembled convex lens and power supply by a picture frame, and is simple in structure, volume is little, is easy to carry.
Description of drawings
The structure explosive view that Fig. 1 implements for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is described further.
Shown in Figure 1, the utility model includes convex lens 1, picture frame 2, battery 9, white lamps 3, purple lamp and gauge tap 11; There is a hole 7 picture frame 2 fronts, and convex lens 1 are set in the hole 7, and convex lens 1 are Ф 21mm, 10 times of three layers of eyeglasses, its edge is provided with purple lamp 5, and purple lamp 5 adopts the LED lamp, have a plurality of, evenly be arranged on convex lens 1 around, white lamps 3 is white white temperature lamps that diamond is identified usefulness, white lamps 3 employing warm white LED lamps, 5300～5500GIA standard color temperature, white lamps 3 is arranged to annular, is arranged at the top of convex lens 1, and has gland 4 and fix;
The afterbody of picture frame 2 also is provided with 15, one 12 of axis holes and wears wherein, and axle 12 two ends are fixed with mirror holder 14, mirror holder 14 be about two structure, the edge of this two chip architecture couples together by mirror holder limit 13.
During operation instruction, according to just (+), negative pole (-) (positive pole up, negative pole down) the LR927 electronic cell is installed, in the present embodiment, battery adopts 3, loads onto battery cover after installing battery.
Regulate to the left and right sides and stir gauge tap 11, can turn on white lamps or purple lamp respectively, gauge tap 11 is adjusted in the centre position, then the lamp source is closed.
Convex lens are placed the observing object top,, observe, identify accurately to defocused.
After finishing using, powered-down.
When light source do not work or light source faint when dim, the electronic cell that please more renews.
This product is applicable to accurate observation diamond, bullion, ore, electronic component etc.White light source is used for specialty and identifies diamond 4C, bullion manufacture craft etc.Whether the purple light source is used for examining diamonds fluorescence.
