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. 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. low pressure mercury lamps. 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. 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). 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 … 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. All low pressure mercury lamps wholesalers & low pressure mercury lamps manufacturers come from members. Low pressure mercury vapor lamps provide the most efficient delivery of UVC energy for use in the health care environments. 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 . In this solution, up to 60 UVC low-pressure lamps … The power ratings are from 4 watt to 125 watts. 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. High-efficiency low-pressure mercury lamps offer 30% to 60% higher output at a spectral output of 254 nm and are ozone-free. 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. A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. Hydrogen Spectral lamp. 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. 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. 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. 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. Instead of mercury, amalgam can be used in low-pressure amalgam (LPA) lamps, resulting in an extremely long life while ensuring high-power outlet. Thus a temperature change will cause a substantial change in the UV lamp output. They differ primarily by electrical excitation and ionization levels of the mercury within the lamp and corresponding internal pressures. 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. 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 … We adapt our UV lamps exactly to the needs of our customers, whether standard low-pressure lamps, high-output lamps or amalgam lamps. China Low Pressure Mercury Lamp manufacturers - Select 2020 high quality Low Pressure Mercury Lamp products in best price from certified Chinese Outdoor Light manufacturers, Indoor Light suppliers, wholesalers and factory on Made-in-China.com Product Name Type Power(W) Overall Length(mm) Arg Length(mm) Pipe Voltage(V) Pipe Current(A) Pipe Diameter(mm) Work Voltage(V) Cap Base Tube Material 1 UV lamp 1kw 1000 335 215 135 8.1 22.5 220 ceramics Quartz Glass 2 UV lamp 1kw 1000 230 125 135 8.1 22.5 220 ceramics Quartz Glass 3 UV lamp 2kw 2000 400 280 160 7.5 22.5 220 … 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. Low Pressure (LP), Amalgam Low Pressure (LP) and Medium Pressure (MP) lamps are all mercury-based lamps. Our plant concept for large scale operations is revolutionary. 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. Special types such as U-shaped lamps, electrodeless UV lamps, surface lamps or contour lamps for special applications complete our product portfolio. 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. Find out information about low-pressure mercury lamp. Its wavelength at low pressure ranges between 184 nm and 253 nm. They are available in lengths from the very small at 150 mm to up to 2400 mm. As pressure increases the chance of multiple collisions gets increased. 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. 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. This lamp has a highly stable output predominantly at the 253.7 nm Mercury line. 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). Search nearly 14 million words and phrases in more than 470 language pairs. In addition, rather than being made of ordinary borosilicate glass, the tube is made of fused The lamp is old and has a 4-pin valve style base for connection.
