medium pressure mercury lamp

Definition: A lamp that consists of vaporized mercury to generate light by using an electric arc is known as a mercury vapor lamp. An advantage of these lamps is higher intensity output. Mumbai, Maharashtra. It also used for the photochlorination. The discharge vessel is filled with noble gases with a low pressure in the range of several millibar. The values shown are averages, they vary depending on operating conditions and lamp fillings. Low-pressure mercury lamps. UV MEDIUM PRESSURE LAMPS IRON DOPED These devices exhibit the best characteristics of both xenon lamps and high-pressure mercury lamps. Low pressure mercury vapor lamps are a highly efficient source of UV light, particularly short wavelength UV light (254nm and 185nm). Low Pressure (LP), Amalgam Low Pressure (LP) and Medium Pressure (MP) lamps are all mercury-based lamps. Lamps for Specific Applications By varying the gas filling, doping and the quartz material, the radiation flux and the spectrum of UV lamps can be matched to suit specific applications. On top of that, we will stay at your side to provide continuing support. The spectral emission depends on the properties of the plasma, such as temperature, pressure and atomic as well as molecular content. The UV light radiation properties of standard mercury lamps relate directly to the radiation characteristics of atomic mercury. Our UV germicidal lamps include low pressure mercury lamps that offer the widest range of application possibilities with seven main lamp types as follows: standard and high-output quartz germicidal lamps, quartz compact and GU lamps, standard and high-output softglass lamps, and softglass compact lamps. With an average of 10 times the power density per unit arc length, Aquafine MP lamps have significantly higher power when compared to Aquafine LP amalgam lamps. Further For UV disinfection and oxidation. Spectral output The lamps emit a wide band spectrum in the UVC range. In close collaboration with you, we can find the best technical solution for the requirements of your UV application. Medium pressure UV lamps run at higher levels in every respect, they operate hotter (around 600-900°C), are far less efficient (8-10% at 254nm), cost more to run because of the power input they need, have less than half the lifespan (around 1000 – 4000 hrs) and they have long start-up and cool down times. eta plus electronic gmbh. Unlike most other UV sources, the medium-pressure lamp (MPL) has a polychromatic spectral distribution from 190 nm up to the infrared spectrum. The first mercury medium pressure UV lamps were developed at Heraeus in 1904. The primary use is in the waste water disinfection and ship ballast water systems. This allows lamp efficiency to be In contrast to Low Pressure lamps, considerable amounts of radiation around the 254 nm is emitted. The metal halide UV medium pressure iron doped lamps emit UV radiation with peak emission in the UVA range at 366 nm and 440 nm. Typical applications are curing of inks and varnishes, disinfection of drinking and waste water, ballast water treatment on ships, applications in the food and beverage industries, or chloramin- reduction and disinfection of swimming pools. In addition, UV mercury lamp is further sub-segmented into low-pressure mercury lamp, medium-pressure UV lamp and amalgam mercury lamp. Medium-Pressure Mercury Lamps by eta plus electronic gmbh & co kg. They emit a multiple MPL General Information UV medium-pressure lamps feature a broad, pronounced line spectrum in the ultraviolet and visible range (200 nm to 600 nm) and a high power density of about 100 W/cm². Due to the lower number of lamps, the system complexity and maintenance costs are signiicantly reduced. This is different from fluorescents which use the mercury vapor arc to create a weaker light … In addition to high efficiency, these lamps are characterized by long-life and maintenance-free operation. eta plus electronic gmbh Medium pressure mercury lamp emits UV spectrum of particular wavelength. It uses an arc through vaporized mercury in a high pressure tube to create very bright light directly from it's own arc. When a mercury vapor lamp is first turned on, it will produce a dark blue glow because only a small amount of the mercury is ionized and the gas pressure in the arc tube is very low, so much of the light is produced in the ultraviolet mercury bands.
