Working Principle of UV lamps

Key Facts About UV Radiation and the Formation of• UV lamp Main Operating PrinciplesElectric current through the electrodes pass through the metal vapor discharge lamp. Cathodes, electrons (negative charge) or gas metal atoms colliding electrons spread rise higher energy level. The reaction of collisions with electrons immediately after the completion of radiation energy as they begin to spread. Determining the energy spectrum of radiation is contained in the rebate during the discharge pressure is a determining factor as the metal vapor and gas.• Low Pressure Mercury Vapour UV lamps Home Study FactorsThe pressure of several tons, low pressure mercury vapor discharge lamp, while the reaction of mercury mainly 184.9 nm (185nm) and 253.7 nm (254nm) wavelengths of radiation, but with a choice of different short wavelength of the quartz tube can be prevented dissipation. Wavelengths below 200nm decomposition of oxygen (oxygen is converted to ozone). As a result, the structure of the quartz tube, ozone-producing UV lamp or an important factor in determining the non-producing property to have.High and low pressure mercury vapor lamps disinfect the work is so special about them are very obvious differences. 4cm-150cm long, only 4 for a lamp - a 400Watt power supply range is needed. Some low pressure UV lamps, cold plate electrodes (cold cathode emitters) are performed, some people pre-heat treated (hot cathode emitters) have been active electrodes' are made. In essence cold cathode emitters creates less UV radiation. UV Disinfection procedures for you to get busy with UV dosage we recommend the use of hot-cathode emitters.Low pressure emitters had been burned almost immediately after the maximum level of radiation begins to spread. Low-pressure mercury vapor (low vapor pressure) to be working again very quickly, thanks to ready position after extinguishing the gelirler.Low ateşlenip pressure lamps operate at room temperature to the optimum. Room temperature above and below the lamps which are adapted for places.Medium Pressure lamps, a significant increase in the difference, the dosage of mercury in all mercury discharge has not used the extra time with each, and, furthermore, the ignition and spread of the formation of the fluorescent tube from start to finish during the final electrical arc between the electrodes, there is no limit.These lamps are suitable for running power sources are needed. This choke and ignitor or electronic transformer may be a combination, may account for preferred because of their advantages provided by electronic transformers.• Medium Pressure Mercury Vapour UV lamps Home Study FactorsIf a metal vapor or gas discharge lamp operation from 10 to 20 bar, medium pressure lamps, lamps of this kind happens in this case (as he was called previously, these lamps are high pressure) is called.Medium pressure UV lamp with the main components that make up:• fluorescent tube• A fused-in electricity supply• Electrodes• Gas• MercuryProduced through different stages depending on the application of gas is injected into the quartz tubes. In general, the argon or the mixture of different gases. Pre-calculated and the UV lamp operating voltage determines the injected mercury. In addition to the heavy metal iodide (iodide) to create or mercury spectrumlarındaki spectrumları focused on the points used to fill in the gaps.Foil electrodes and extensions of the fluorescent tube is pressed into the heat of fusion of melt processing and electrical connection, the extension is provided with a tight-knit. Preferably on the voltage applied to electrodes amps limitleyen a conductiveden arc between the electrodes to create the internal gas iyonizeleştirip ısıtacaktır tube to a certain extent.Ignition voltage (approximately 1.7 times the operating voltage) ignition and then again during the fall and rise directly up to 10-50 volts. As a result, many oscillation reaction in the process of mercury and mercury molecules in Vapourise undergoes changes. This process continues until the reaction reached completion, and the electrical values. Electricity when the power source to be ionized gas in the lamp will begin to create from the arc voltage should be determined and the amount of mercury is rising up to the value of certain amount of amps is limited by the power supplies. At the same time after ignition amps predetermined operating level drops (approximately 1.6-fold).Ready during the first ignition of the lamp voltage rise and fall amps until it shows the location of a discharge lamp to the electrical characteristic feature of acceleration values. Based on the foregoing, during firing of the lamp to reflect light from the outside can not be seen in the arc. Arc is captured, but the optimum operating conditions and can be seen in two elektrodtada completed. If the (lamp), or a nominal conditionslar impurities discharge vessel is not reached in this case the arc electrodes can not be fixed and will vary continuously. If a lamp operating voltage in this case, it should be soğutuluyorsa too low to be observed, such as the parameter values ​​of the lamp base can be taken to ensure the optimum operation conditions. In such cases, the minimum power of the lamp where the arc is completely cut off loaded (lamp may be disabled).Due to the high pressure and temperature inside the lamp goes out again immediately after the burn, because it will not be the collision of electrons between the electrodes is not the formation of the arc. Vapor pressure of the lamp is lit the lamp again fall will be arrested in its own specific initial value.Ampere is always required before starting the lamp ignition voltage and the values ​​achieved in flawless condition.
