This answer is No. LED light-emitting device made of a single wavelength or mixed wavelength spectrum.In fact,It is actually a band of light,
we has been measured with a spectrometer.the Liquid or solid material inspired by high temperature, emit light of various wavelengths, such as incandescent light, sunlight and hot iron electrode various wavelengths are emitted continuous spectrum.This spectrum is formed by the hot solids  ,liquids or high pressure gases

Follows we think the shape means As shown in the spectrum of a LED,now ,Most of led was used blue light(centered band at 460 nm)
chip and yellow light phosphor composition a superposition of continuous spectrum:

there are several LED, for example, traffic lights, each LED particle is only one color,the composition seen one as linear, emission of light must be in here region;

The other oneis a three-color LED(it contains the RGB three colors ).we could think that it is line spectrum, but there are still several or tens of nanometers in width) mixed spectra are as follows:

The effect—–You see that the white LED is made of blue + Yellow 2 or R+G+B3 kinds of take out .

In Generally,Can checking up Paper money for under 410 nm of Violet LED. But every one should know that different ultra-violet are different Result. where is the pathos?

The detection of fluorescence reflection of the color difference are their main factor. The violet led was “gray white fluorescent” for over 400nm(or equal to  400nm). it under 400nm lower(reflection fluorescence color tends to the “golden” low in 400nm)visual effect is more obvious, lower the band is getting higher price. So Detection equipment wavelengths of Violet both have 380~410nm in town.Violet LED around the Paper money as follows; major in currencies such aspound, US dollar, euro, franc used 360-380nm Violet LED, 365nm effect best in generally .pound, dollar, euro, and franc able to detection and 390nm or above the 390nm is no reflection fluorescence,380~390nm very weak. so they looks unfit for detection duty.

The advantages and disadvantages of ozone ultraviolet light strip disinfection

UV led strip Will produce a 185nm wavelength of ultraviolet light, this wavelength of ultraviolet light can be outside air O2 into O 3 (ozone), ozone is a active molecules, ozone can do Chemical reaction easily with other molecules.causing further decomposition and converted into oxygen, to get purpose that update of fresh air & deodorant sterilization.Because of the need of application, there are many kinds of uv products, such as low ozone (no ozone), ozone, high ozone, and so on.in Generally there are staff of the action,does not recommend the use of ozone ultraviolet light disinfection,Breathe in the oxygen (Contained ozone of air)，causing the body’s oxygen deficiency, the occurrence of dizziness, nausea, the impact of health. 

What is the application of ultraviolet UV lamp?
UV lamps are widely used in the fields of LCD, PCB, electronics, printing, plastics, wood, shoes, glass, craft and so on.
1, spray: In general cell phone shell coating, cosmetic case, MP3 small appliance shell and other plastic spray companies also need it!Casing spraying with uv printing both industry requirements  it’s not the same when give it the works(look at it products and equipment),
2, printing: silk screen printing, offset printing, 5-color printing mostly use UV lamp drying and curing UV ink.
3, shoes: use of ultraviolet irradiation of the soles’ material,
So that makes two of the adhesive rubber soles and uppers was better than nature.
4, wood: only the surface of the UV paint coating curing. Because UV paint (light oil or varnish, etc.)has good performance: such as wear resistance, acid and alkali resistance, weather resistance, etc.
5, PCB industry: PCB is a circuit board, UV lamp for circuit board printing, In general use METAL (metal halide lamp), there is also a kind of exposure lamp( also belongs to metal halide lamp), when PCB production, for the exposure of developing, in general use in circuit board company. There be an important Application: exposure of Solder Mask with uv led strip.
6, LCD industry: Display of LCD Has adopted low pressure cool UV lamp, and curing with the lamp is not the same, but all belong to the UV lamp, use is not the same.
7, craft: as long as the use of UV on the surface of the oil processing, can be used in ultraviolet light.
8, uv automatic coating line: electrostatic dust gun is used in pre-treatment project, or electrostatic dust stick to deal with.

Disinfection with UV LED strip
People was close to that bacteria and viruses everyday routine. Therefore, to develop good health habits. it’s import thing that regular disinfection。Howerver, people have not the conditions that bring the high pressure steam or ethylene oxide on anytime.but common disinfectant wipes, and so disinfectant of warm water is very unreliable ( for all kinds of microorganisms).LED UVC sterilization, real-time and high efficient, in 2 minutes to reach 99.9% of the sterilization rate, and cold cathode lamp need 6-8 minutes.

*The  ultravilet（www.ledlightmake.com/infrared-ultraviolet-led-strip-c-80_92） LED passed the EU RoHS environmental protection certification, does not contain harmful gas emission and common heavy metal packaging technology

Quality, such as mercury, cadmium, lead, bromine and other substances.

*The physical sterilization, no pollution, no smell, no residue, no toxic side effect.

*LED – very low energy consumption, save battery consumption, compared with the traditional cold cathode lamp, energy saving 80%.

*The switch (above 105Hz frequency modulation), instant start, adjustable lighting, which makes deep UV led the actual service life is much longer than that of mercury lamp and save more battery, easy to carry.

*The high brightness, the effective is five hundred times to thousands of times than mercury lamp unit area output band.

A lot people need a white light source when Development of LED project. Development of white LED in 1998. This LED is made by a GaN chip and yttrium aluminum garnet (YAG) package together. GaN chip as blue (p=465nm, Wd=30nm) lightl, high temperature sintering made of YAG containing Ce3+ phosphor emitting yellow light emission  by this blue light, peak 550nm.Blue LED substrate is mounted in the reflective cavity bowl, covered with a thin layer of resin mixed with YAG, about 200-500nm. The blue part of the LED substrate is absorbed by the phosphor,and the other part is mixed with the yellow light can geted white.adjust the thickness of the phosphor layer and changing the YAG phosphor chemical composition of the phosphor layer can the 3500 – 10000 K color temperature colored white.  Import thing is the medium that between the two poles of the light-emitting diode, powder, and called the phosphor, different media emit different colors of light.

In the past a long time, people’s awareness of UV is vague,Dangerous, even harmful. Even the sunlight is dangerous to them!They does not know that there is a beneficial side of ultraviolet radiation on the human body. can help bone growth
First, Medium wave of ultraviolet radiation,can make the deoxy cholesterol into vitamin D in skin. vitamin D enhances the absorption of calcium and phosphorus in the body,growth of children More contact with sun,more activities on outdoors.help prevent rickets.Recently, office’workers in the incidence of rickets has increased, the reason is * closed working environment
*they’s almost con’t touch the sun All day.

Secondly, different wavelength UV-A, UV-B ultraviolet radiation can treat rheumatoid arthritis, lupus, psoriasis, scleroderma, vitiligo, pityriasis rosea and cutaneous T cell lymphoma and skin diseases. But studies suggest a link to  lupus erythematosus shows that patients treated with ultraviolet radiation can significantly reduce the symptoms. and with the extension of treatment time, the effectiveness of the treatment continues to increase.

Again, UV Can also make the microbial cell nucleic acid and protein puree chemical change, to kill microorganisms, uv led strip were conducting an
Sterilization on air, water and polluted surface.

In summary, the three bands of A, B and C have a qualitative damage to the surface of the biological. The most effective band of the three bands is C band, and the wavelength is 253nm. The bactericidal activity of 7Nm was the strongest.

Molecular absorption of electromagnetic wave, from a kind of physical phenomenon known as “resonance” .For example, we used to say don’t Marchwhen a large force across the bridge.This is afraid of thepace of vibration and vibration bridge together, (vibration always exists objectively, just some weak so it is difficult for us to feel, but the instrument can measure.)then “overlay”.Load increases  bridge vibration cause landslides. This is a common “resonance” phenomenon.

Similarly, there is also a “vibration” of a different kind of energy levels in molecules inside,  equal to the energy of two different energy level difference when Externally added energy .the molecules will absorb the Externally added energy , which is the “resonance”  of atomic molecular level.Ozone can absorb ultraviolet light, which is due to the molecular structure that it can be Produce the “resonance” with the ultraviolet radiation(within a certain range).ozone be skilled in, just absorb specific part. However, it absorbs part happens could lead to skin cancer, that means a lot coming from “murderer”, We think it exists for many kinds of molecules. The mean,  just different for absorbing electromagnetic wave.

About Ozone we knows that it is atmosphere‘live be short of Ozone（the atmosphere is both indispensable (ozone layer)），and it is also a kind of environmental pollutants, some people said oxygen can produce ozone in the ultraviolet irradiation, does that mean to the face of the earth。In here have enough oxygen, The oxygen would be have reacted Above.
thus ozone is an air pollutant, so that the ozone is harmful, and some people say that ozone can absorb ultraviolet light, The conclusions that It was just supposed to be the high-altitude ozone layer(the Earth’s surface from the 14- 25 km altitude).ozone layer, the ozone layer in the earth’s outer space, the sun’s ultraviolet radiation Creating a ozone layer in the earth  Outer space.

Until the atmosphere is stable,the ozone layer is security blanket for people live. in normal circumstances . The ozone layer is stable; it is always to protect people from ultraviolet rays.So, “ozone can absorb ultraviolet rays, ultraviolet Produce ozone” is not contradictory, but these two reactions occur in different position in the atmosphere, There is no relationship between the two.

Hang my clothes lay in the sun,  the use of which the ultraviolet disinfection. Everybody knows that. Well done. Hoo-rah.  But I still have doubts that the ultraviolet disinfection is probably a little andfiniteBut in recent days of an experiment, let me taste of the power of ultraviolet rays in sunlight! (Of course, the experiment is not to measure ultraviolet).
Recently, we manufactured it —–PCB with photographic blue oil, To the exposure, I do not have use UV LED strip. When exposure, I no ultraviolet light – follow www.ledlightmake.com  production of information, just need a few minutes with 8W UV LED to exposure. Other Information also mentioned that if user no have ultraviolet LED light, you can use sunlight or energy-saving lamp to exposure. First I chose to use 12-watt energy-saving lamps to exposure. after 5 minutes, but no effect.Then we had to choose sunlight exposure. The first time to use Sunlight  no experience, the sun for 5 minutes, the exposure is over, 2 minutes is the best time of exposure for PCB.I can’t believe 2 minutes did this. We  would think that PCB stayed there for half an hour.
