Translation for: 'low-pressure mercury lamp' in English->Spanish dictionary. The average life of tube lights is about 5000 hours and also they are very cheap, hence they are very popular. A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. These lamps have a special coating that allows for transmission at 254nm only or 254nm and 185nm for ozone production. The low-pressure Amalgam lamps achieve ten times the UV power density of standard low-pressure lamps and five times more ozone production while operating at a higher temperature than conventional low-pressure Mercury lamps. Low pressure mercury fluorescent lamps are commonly called tube lights. Broadly, practical discharge lamps for lighting are either mercury vapour or sodium vapour lamps, at either high or low pressure. They are available in lengths from the very small at 150 mm to up to 2400 mm. Find out information about low-pressure mercury lamp. China Low Pressure Mercury Lamps - Select 2020 Low Pressure Mercury Lamps products from verified China Low Pressure Mercury Lamps manufacturers, suppliers on Made-in-China.com. Up to 10 times the UV power density of an LPM lamp can be achieved, and they can be used at higher ambient temperatures of up to 90C. Thus a temperature change will cause a substantial change in the UV lamp output. Mercury vapor technology was developed throughout the s in England and Germany. Special types such as U-shaped lamps, electrodeless UV lamps, surface lamps or contour lamps for special applications complete our product portfolio. Lamp Construction It consists of 2 electrodes made up of an alloy of tungsten which is placed together in a medium containing mercury vapor and 25-50 torr of pure argon gas. A mercury-vapor lamp whose partial pressure during operation does not exceed 0.001 atmosphere; fluorescent and germicidal lamps are included in … The effect this has is that although similar in size, they’re cheaper, cost less to run and are far safer to be around (Your unlikely to get burned or scalded if there is no flow through the chamber for a prolonged period). We doesn't provide low pressure mercury lamps products or service, please contact them directly and verify their companies info carefully. Instead of mercury, amalgam can be used in low-pressure amalgam (LPA) lamps, resulting in an extremely long life while ensuring high-power outlet. Low-pressure mercury lamp: Historically, the most common type of lamp used to produce UVC radiation was the low-pressure mercury lamp, which has its main (>90%) emission at 254 nm. Hydrogen Spectral lamp. It uses hollow cold cathodes and requires 5kV to strike the starter gas (probably Argon). Gas-discharge lamps are a family of artificial light sources that generate light by sending an electric discharge through an ionized gas, a plasma.Typically, such lamps use a noble gas (argon, neon, krypton, and xenon) or a mixture of these gases.Some include additional substances, like mercury, sodium, and metal halides, which are vaporized during startup to become part of the gas mixture. Lamps §Low-Pressure Mercury Discharge § The most common form of germicidal lamp looks similar to an ordinary fluorescent lamp but the tube contains no fluorescent phosphor. All low pressure mercury lamps wholesalers & low pressure mercury lamps manufacturers come from members. Low-pressure mercury lamps The most common form of germicidal lamp looks similar to an ordinary fluorescent lamp but the tube contains no fluorescent phosphor . Low pressure germicidal lamps have an operating lifetime of up to 12,000 hours and convert up to 40% of the lamp’s electrical power into UVC, offering an efficient and cost-effective alternative to medium pressure mercury lamps for water, air and surface disinfection systems, as well as controlling unwanted odours in the air. Mercury lamps with specific spectra (e.g., with monochromatic light at 254 nm from a low-pressure lamp), xenon lamps, and deuterium lamps (with continuous spectra) are also used. Tru-D’s bulbs are as safe as any low pressure mercury vapor fluorescent bulb in your facility and pose no danger to staff or families. They differ primarily by electrical excitation and ionization levels of the mercury within the lamp and corresponding internal pressures. Low Pressure (LP), Amalgam Low Pressure (LP) and Medium Pressure (MP) lamps are all mercury-based lamps. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp … 21.5.2.2 Run-up efficiency Smith devised a method of calculating the ‘Run-up efficiency’ of a discharge lamp (see Lighting for Health and Safety , Butterworth-Heinemann, ISBN 0 … Low Pressure Mercury Vapour Lamp HG-2 Lamp Heraeus has developed a compact low pressure, low voltage Mercury vapour lamp type HG2, principally for use in scientific instrumentation. The UV lamps are suitable for most applications in air and water. However, the first low-pressure lamps were sold commercially in the United States in after John Cooper Hewitt innovated the lamp's color spectrum from blue-green to white. Most of the mentioned sources do not present a significant exposure to UV radiation under normal use, but electric welding arcs and some other arc lamps are strong sources of UV radiation. low pressure mercury lamps. Again transition of the electrons requires least amount of input energy from a colliding electron. 254 nm UV Lamp and 185nm Ozone Generating Lamp 254 nm UV Lamps L ightSources & LightTech’s low-pressure, mercury-arc germicidal 254 nm UV lamps are specially designed to produce the highest amounts of UV radiation – where 90% of the energy is typically generated at 254nm. The power ratings are from 4 watt to 125 watts. Introduction. We adapt our UV lamps exactly to the needs of our customers, whether standard low-pressure lamps, high-output lamps or amalgam lamps. A Low pressure Mercury UV lamp, shown below, is made with a quartz tube. mercury medium pressure uv lamps Pursuant to Articles 7, 13 and 23 of Legislative Decree N. 196/2003, I hereby declare to have acknowledged the general information provided by Helios concerning the treatment of my personal, and possibly sensitive, data, to have been fully informed of my rights and that I know how and where to exercise them. Our plant concept for large scale operations is revolutionary. In this solution, up to 60 UVC low-pressure lamps … Low pressure mercury vapor discharge lamp having a cylindrical discharge vessel the inner surface of which is, at least partly, coated with a luminescent layer, a reflecting layer containing titanium dioxide being provided between the said surface and the luminescent layer over a portion of the circumference between the ends of the discharge vessel. This lamp has a highly stable output predominantly at the 253.7 nm Mercury line. Standard low-pressure mercury lamps made of synthetic or natural quartz glass have spectral output at 254 nm and 185 nm and are ozone-generating. We supply highly developed control units for UVC low-pressure lamps and UV medium-pressure lamps with support to plant manufacturers in the design of their UV installation. As pressure increases the chance of multiple collisions gets increased. UV lamp 5kw 365nm High Pressure Mercury Lamp No. Its wavelength at low pressure ranges between 184 nm and 253 nm. In addition, rather than being made of ordinary borosilicate glass , the tube is made of fused quartz or vycor 7913 [2] glass. Low pressure lamps run at lower temperatures (around 45°C ) and operate far more efficiently than their medium pressure counterparts (around 35% output at 254nm). UV germicidal low pressure mercury lamp R 750nm 700nm 650nm 600nm 550nm 500nm 450nm 400nm 350nm 300nm 250nm 200nm 150nm 100nm 315 280 Infrared Visible light UV-A UV-B UV-C Vacuum-UV X rays. UV Lamp Temperature Characteristics INTRODUCTION The optical and electrical parameters of low-pressure (LP) ultraviolet (UV) lamps are closely related to the mercury vapor pressure in the lamp, which in turn are closely related to the temperature. In case of fluorescent lamp the mercury vapour pressure is maintained at lower level such that 60% of the total input energy gets converted into 253.7 nm single line. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.
