What is an ultraviolet lamp for?
Title: Quartz and ultraviolet 
Ultraviolet e was discovered earlier than 200 years ago, but since it was invented on the basis of artificial sources for ultraviolet radiation, someone has managed to use the amazing properties of the invisible light on the pelvis. Dnes ultraviolet lamp helps in combating a lot of diseases and disinfection, allowing it to be used on new materials and from forensics. But for yes, UV devices are useful, not harmful, it is necessary to clearly understand how they are and for what they serve.

What is the ultraviolet radiation and how are the cases
You probably know that light is not electromagnetically isolated. Depending on the chastota, it blooms on such a change for me. The low-quality spectrum is not black, but the high-quality spectrum is blue. Ako increase the frequency even higher, then the light will become a lilav and then completely disappear. For sure, I disappeared for the lamb. The generality of the radiation is generally in the region of the ultraviolet spectrum, which we cannot but see for the sake of particularity at a glance.
But if you don’t see the ultraviolet light, it doesn’t mean that it doesn’t influence you in any way. You can’t but deny that the radiation is harmless, but we can’t but I see.And the radiation is nothing more than from electromagnetic radiation of cato-svetlinata and ultraviolet, it’s very honest.
But yes, let's take a look at the ultraviolet spectrum. To that se namira, somehow razbrahme, between visible light and radiation:
Dependence on the view on the electromagnetic radiation from the negligible purity
Let’s get rid of light with radiation and look at ultraviolet light near:
Divided into ultraviolet range into subranges
Figurata clearly shows why the UV range is conditionally divided into two sub-ranges: near and far. But in the figure above, we can see the division into UVA, UVB and UVC. In the future, the division is exactly the same - ultraviolet A, B and C, which is clearly outlined in the exposition on radiation at the top of biological objects.
Properties on ultraviolet radiation and neurotoxemia
And so, the imam has three ultraviolet ranges for location: A, B and C.
Ultravioletova A
The radiation of the semester is in the range of 400 - 320 nm and the senarich mek or long wave ultraviolet. Penetrated into the long layer layer on the weave is minimal. When used in moderation, UVA is not in itself not harmful for the body, but it is also beneficial. Strengthening the immune system by increasing the production of vitamin D and improving the condition of the skin. It is under the basin of the ultraviolet rays of the sun baths on the beach.
But in the case of predosed dori lek ultraviolet radiation, the range may represent a known danger for horata. A good example: stignah to the beach, lag for a few hours and "outcasts". Do you sound familiar? Unremovable.But it could be even worse, but they lay for about five hours, or from the opening of their eyes and without high-quality sun eyes. With prolonged exposure to UVA, it can cause burns on the cornea and burn the skin literally to the fur.
Ultraviolet B
Medium ultraviolet, covering the range from 320 - 280 nm. Ultraviolet treatment with the pelvis length on the upper abdomen in the state and penetration into the upper layer of the living tissue and cause serious damage to the structure, to partially destroying the DNA. and bream. Such radiation is very dangerous for plants and for many types of viruses and bacteria, for small amounts, UVB is catalytically fatal.
Ultraviolet C
Nay-kasata long-range and nay-dangerous range for all creatures, some including ultraviolet light from long-range to 280 to 100 nm. UFS, dory in small doses, e in state and destroy the DNA chains, causing mutations. With chorata, as a rule, it is stated that it causes skin cancer and melanoma. Because of its ability to penetrate far enough into fabric, UVC can cause irreversible radiation damage to retinate and long-term damage to leather.
Additional hazard capacity for ultraviolet radiation from category C and ionizing oxygen molecules in the atmosphere. As a result, on such a presentation in the air, it forms ozone - triatomic oxygen, which is the strongest oxidizing agent, and is gradually dangerous for the biological object of that belonging to the paravata, the most dangerous category of poison.
Device with UV lamp
Chovekt se e taught yes by creating artificial sources for ultraviolet radiation and they can and izluchvat in all given range. Structurally, the ultraviolet lamp is directed under the format on the cap, with an inert gas with an impurity on the metal zhivak. Remove to the kolbat sa solder the refractory electrodes, which is why it has applied a protective voltage to the device. Under the influence of this voltage in the ground, the light discharge, which kills the molecules and reduces the ultraviolet light in the UV spectra.
Design on UV lamp
Workers cut from a certain material, designers can cut off radiation from a defined length to length. Thus, the lamp, made of black glass, passes only ultraviolet radiation type A, the uvio bulb is more transparent beyond UVB, but does not pass hard UVC radiation. Ako kolbat e is directed from quartz glass, then the device is thinner and trite the type of ultraviolet spectrum - A, B, C.
Vsichki ultraviolet lamps and gas discharge lamps and trembling and bydat connections to kam mrezhata through a special ballast (EKG). On the other hand, they illuminate the discharge in the bulb, which is not amusingly transforming into an uncontrolled random discharge.
Electromagnet (highly) and electronic ballast for UV lamps with discharge
Important! Crush with a hot scoot ss blue crush, which is often used for contamination with UNG disease, not sa ultraviolet. Tova sa put the flasks out of the burnt flask, and serve the bruise flask for yourself so that you don’t get thermally burnt out and don’t damage the eyes from the bright light, which keep the lamp close to the face of the si.

UV lamp application
And so, UV lamps exist and dory know how they look like. But for what? Today, ultraviolet devices are used widely both on a daily basis and in production. Base areas per application on a UV lamp:
1. Change on the physical properties on the material... Under the influence of ultraviolet radiation, some synthetic materials (fights, varnish, plastics, etc.) can and will change the properties of si: yes, se vvardyavat, omekotyavat, colors and other physical characteristics will change. The example of dentistry is alive. A special photopolymer film of plastics, dokato heal, a trace of this installer, illuminate the oral cavity from the mek of ultraviolet light. The next is the processing of the polymer, becoming healthier from the kamka. In the salon for beauty, this is a special gel, which is used under a UV lamp. With negov help, for example, kosmetitsite udlzhavat noktite si.
A trace of a tretirane with an ultraviolet lamp burns, mek kato plasticine, adding an exceptional health.
2. Criminalistics and penal law... Polymer, which can and shine in the ultraviolet light, behold, it is widely used for the protection of cross-country falsifications. For fun, try and light up the bastard with an ultraviolet lamp. After starting, you can check the banknote for almost all pages, authenticity for especially important documents or stamps on the top (so-called “Cerberus” protection). Criminologists use ultraviolet and lamps for opening on the watch for blood. That one, take it all apart, do not shine, but it absorbs ultraviolet radiation and is completely black against the general background.

3. With a deficiency in natural ultraviolet therapy. Used on a UV-A lamp for biological objects, it was discovered almost simultaneously with this invention. With lipsa on a natural ultraviolet treatment, the immune system suffers, leather adding an unhealthy pale nuance. Ako plants and grow blooming, you can see the back of the glass on the seer or under the lamps with a burnt bug, then they don’t feel good - they’ll grow badly and often hurt. Everything is connected with lipsate to ultraviolet radiation from the A spectrum, lipsate is especially harmful for something. The days of UVA lamps are used for relying on immunity and picking up on the skin at all times, some of them are naturally bright.
Used on UV A lamps to compensate for deficiency on natural UV treatment
The capacity of the device, in order to compensate for the deficiency in natural ultraviolet light, emits not ultraviolet A itself, but also B, contrary to the latter, the total radiation is extremely small - from 0.1 to 2-3%.
4. For disinfection... Vsichki viruses and bacteria are living organisms, they are very intelligent little ones, it’s not difficult to “prepare” with ultraviolet light. Tvardata ultraviolet (C) bright e in the state and always literally without any microorganisms, destroying the structure. According to the disease, it starts from the B and C spectrum, the names are antibacterial or bactericidal, and can be used for disinfection in the apartment, public institutions, air, water, objects and dory for the treatment of viral infections. When used on a UFS lamp, ozone acts as an additional disinfection factor, for some writings in a mountain.
Used on UV lamps for disinfection and antibacterial treatment
Probably the medical term kato quartz came from the same way.The Tazi procedure is not the same as tretiran on the subject or the body is strictly dosed with ultraviolet radiation.
The main characteristics of the source for ultraviolet radiation
What are the characteristics of UV lamps and guide you, for you to get the maximum effect when used and not to harm your health and that of others? Here is the basic from tyah:
- Coverage for radiation.
- Power
- Appointed.
- Stomach.
Excluded girth
Tova e main parameter. Ultraviolet rays act differently depending on the length of the wave. Ako UVA is not dangerous in itself for the eyes and, if used correctly, without presenting a serious flare for the body, then UVB may not in itself damage the eyes, but also yes provokira dalboki, some irreversible fumes on the skin. UVC is not a great disinfectant, but it can pose a deadly hazard for horata, cathoradiation from the body to the body, destroying DNA and forming ozone gases.
From a different country, UVA spectrum is completely useless as an antibacterial agent. In practice, yama yes ima crawled from a takawa lamp, for example, when cleaning the air from microbes. Osventova some species of bacteria and microflora will become more active. To begin with, when choosing a UV lamp, it is necessary to clearly understand how it is used and how the spectrum on the radiation is shaking.
Power
Tova se nasya to silat on UV flux, taken from lampat. The same is proportional to the energy consumption, therefore, when the device is selected, they usually focus on the top of the indicator. Home UV lamps usually do not exceed 40-60 watts, professional devices can power up to 200-500 W or more. Firstly, usually imat lowly in a kolbat, and second high.Whenever you choose a radiator for determining the purpose, you can clearly understand what, in relation to power, more than not wine means good. For yes, you will get the maximum effect, if it is used for the device, it is shaking and if it is strictly dosed. This is why, once you bathe the lamp, you will pay attention not to its purpose itself, but also to the change in the area to the room or the productivity to the device, but to serve for cleaning the air or water.
Purpose and design
The purpose of this ultraviolet lamp and se is divided into bitovi and professional. The latter is usually imat for a high power, for a wide and wide emission spectrum and for a more complex design. This is for those seeking a qualified specialist and answering the knowledge for the service. If you buy an ultraviolet lamp for home use, then it’s better to refuse a professional device. In Tozi, the case of the likelihood of lampat and harm will soon golyama. This is especially important for devices operating in the UVC range, which is somewhat ionizable.
According to the type of design, the ultraviolet lamp is divided into:
1. Open… These devices emit ultraviolet light directly on Wednesday. When used incorrectly, they represent a nai-golyama danger for the body, but allow high-quality disinfection of the room, including the air and all objects into it. Lamps with an open or semi-open design (radiation is clearly saturated) are used for medical purposes: treatment for infectious diseases and treatment for deficiency in ultraviolet radiation (phytolampi, solarium).
Used for bactericidal lamps for antibacterial treatment on premises
2. Recirculators or devices from closed type. The lamp in the world is completely opaque in the back, and the self-working medium, gas or fluid, is moved from a special pump to the chamber by UV investigation. On a daily basis, this recirculatory is usually used for bactericidal treatment on water or air. This cato device does not emit ultraviolet light, if you use it correctly, you are completely safe for the chorus and can even use it in a good presence. Recirculatory can and can be used somehow bitovi, such and industries.

3. Versatile. Devices from the tosi type can and work somehow in the mode for recirculation to the air, and also with direct exhaust. Structurally directed cato recirculator sgvaem body. The recirculator is in the form of an ordinary recirculator, from the opening of the curtain - a bactericidal lamp from the open type.

Stomach
The principle and structure of an ultraviolet lamp are similar to the principle and structure of a fluorescent lighting device, but it is logical to assume that the technical performance of the operation will reduce the stomach and can reach 8,000–10,000 hours. In practice, tova is not completely true. According to the time for the work of the lampat "old": the bright stream is painted. But while the usual lighting lamp has a tosi effect, it is visually white, then it is impossible to check the UV lamp “by eye”. The range of the manufacturer is limited to a much shorter operating life: from 1000 to 9000 hours, depending on the power per lamp, its purpose and, in terms of quality, on material, component and markat.
But in the passport for the device, there is no indication of a change for a lampat or a maximum period of 20 hours or more, then refuse and purchase such a device. Tvarde niskata the price of the device is a warning and a warning. Nai-probably low quality product or dory fake.
How dangerous is UV treatment
So, ultraviolet is dangerous, very well, a lot of the choir know a lot of little things for their properties and can send something often. In the world of ima, there is a lot of deadly, but we know for the tazi the danger from childhood or see the crying with your own eyes. Almost no one is interested in ultraviolet radiation, but it is invisible behind the human eye. You don’t need to insure yourself against UV lamps, try and know how to use it correctly. Here are some tips that will help you and avoid trouble when working with UV devices:
- Use Ureda for its intended purpose.
- Strictly follow the instructions for use provided with the device.
- Do not exceed the prejudice of time at idle time lamp for ten... Tova is a flash with a serious and somewhat irreversible aftermath of up to 2 degrees on radiation exhaustion.
- Regardless of the purpose of the lampata and neiniya radiation spectrum, use protective glasses.
- Do not use the sunken eyes for protection on the eyes: they are not prone to reflected light and absolutely not the purpose for the tazi is intact! It’s a lot safer to shut up your eyes quietly, without yes, you’ll experience it and get out from under the riveter.
- After that, turn on the anti-bacterial UV lamp, removing UV B or C, let the flocks and take your pets and plants with you.
- A coste used a UVC lamp for disinfection in the room, after you ventilate the room well from ozone, which is formed over time during the work of the mud - it's deadly!
Here you go, you can read the trace of this tazi statia, if you can and sort it out, crawl, be in danger and be able to use one modern UV lamp and let me crawl to the maximum, without harm to myself.
