Abstract
The utility model relates to a heat radiation type ultraviolet lamp authenticity testing device which is characterized in that the heat radiation type ultraviolet lamp authenticity testing device is composed of an incandescent bulb (4), a battery (5), an ultraviolet filter (2), and a casing (6). When the heat radiation type authenticity testing device is turned on, the bulb is contacted with the battery, and the ultraviolet filter is arranged in front of the bulb. The utility model has no need of a special power supply line, and has advantage of portability, low cost, convenient application, etc.
Description
The utility model relates to the counterfeit money authentication technique, specifically a kind of thermal radiation formula uviol lamp fake-identifying instrument.
For preventing counterfeit money and counterfeit goods of poor quality, various countries have adopted the fluorescence falsification preventing technology, are printed on false proof secret mark on the ad-hoc location of patterns such as banknote, security, trade mark, packing.On 50 yuan, 100 yuans that China issued after nineteen ninety the fluorescence secret mark is arranged also, this fluorescence secret mark is invisible under visible light, but in the dark nextly clearly illustrate out ultraviolet ray excited, because applying of fluorescent technique, to preventing counterfeit money, guarantee that consumer's interests play an important role.
In the fluorescence falsification preventing technology, the means of discerning the false from the genuine produce ultraviolet uviol lamp exactly.And the quartz burner that the uviol lamp that is used for fake-identifying instrument at present all adopts gas discharge to excite, the uitraviolet intensity height that this pipe produces, spectrum is purer, but because the price height of this pipe, and need to use 100 volts of above high pressure to excite, relevant complex circuit, therefore the fake-identifying instrument made from the ultraviolet pipe, price height not only, line failure is difficult for letter to be repaiied, and usable range also is restricted.
The purpose of this utility model is to provide a kind of easy, not fragile, low-cost thermal radiation formula uviol lamp fake-identifying instrument.
The utility model is achieved in that by incandescent lamp bulb, battery, UV filter and shell to be formed, and bulb contacts with battery during unlatching, and UV filter places the front of bulb.Bulb adds thermoluminescence through battery, promptly obtains uviol lamp after ultraviolet filter filters, and is used to check the fluorescence secret mark.
Its principle is as follows: when common tungsten lamp adds thermoluminescence, its spectral series one continuous spectrum, include ultraviolet light-visible light-ultrared whole spectrum, as shown in Figure 1, but each intensity difference partly, in the spectrum of heating tungsten lamp radiation, the strongest part mainly can see infrared part, wherein also have the short near ultraviolet of wavelength ratio 0.4 μ m partly, but its intensity a little less than.Only be below 10% of the strongest wavelength X m intensity, yet also can see that along with the tungsten filament temperature raises, ultraviolet intensity partly is also along with increase by figure.Therefore, if utilize a ultraviolet filter that the visible light in the continuous spectrum is partly absorbed, and only allow ultraviolet ray pass through, this just forms the heat radiation type uviol lamp.The ultraviolet filter that the utility model adopts its peak-peak wavelength after measured is 0.3984 μ m, and half width is 0.3687 μ m and 0.4172 μ m, is enough to excite a lot of fluorescent pigments to send fluorescent.Therefore, if utilize ordinary incandescent lamp to add that ultraviolet filter just can be assembled into the uviol lamp fake-identifying instrument easily.
The utlity model has following characteristics: can utilize ready-made incandescent lamp bulb, and the bulb damage, can change easily, do not need special power circuit, easy to carry, cost is low, and usable range is wide, is easy to apply.
Fig. 1 is an incandescent lamp radiant light continuous spectrum
Fig. 2 is the spectrogram that sees through of ultraviolet filtering built-in testing
Fig. 3 is a structural representation of the present utility model
Among Fig. 1, I is the relative intensity of spectrum, and λ is a wavelength, and λ m is the peak wavelength under the respective wavelength.
Among Fig. 2, a, b are the half width wavelength, and c is a peak wavelength.
Among Fig. 3,1-slide, 2-ultraviolet filter, 3-cell switch, 4-Spot light bulb, 5-battery, 6-shell, 7-intermediate plate.
Embodiment, as shown in Figure 3, the utility model is made up of incandescent lamp bulb 4, battery 5, UV filter 2 and shell 6, and bulb contacts with battery during unlatching, and UV filter places the front of bulb.Wherein incandescent lamp bulb adopts 2.2V, 0.2A light harvesting bulb (also can be tungsten lamp, iodine-tungsten lamp or other resistance heated and the width of cloth is penetrated the lamp of visible light), after battery 5 heating that are loaded in the shell 6, send very strong light harvesting bundle, this light beam blocks visible light and only allows ultraviolet light pass through by UV filter 2, forms the heat radiation type ultraviolet light.On intermediate plate 7, there are cell switch 3,7 and shell 6 to be connected as a single entity.
Fake-identifying instrument of the present utility model, can clearly show when shining darkling 100 yuan, 50 yuans fluorescence secret mark of distribution in 90 years.It can be differentiated effectively to various banknote, security, the trade marks that are shaped on the fluorescence secret mark fully.
Claims (3)
1, a kind of thermal radiation formula uviol lamp fake-identifying instrument is characterized in that being made up of incandescent lamp bulb (4), battery (5), UV filter (2) and shell (6), and bulb contacts with battery during unlatching, and UV filter places the front of bulb.
2,, it is characterized in that incandescent lamp bulb can be tungsten lamp, iodine-tungsten lamp or other resistance heated of various power and the width of cloth is penetrated the lamp of visible light by the described fake-identifying instrument of claim 1.
