I am searching Hg arc lamp that can give millimeter and sub-millimeter wavelength radiation for THz application. I am looking for the nice solution to cut off spectral lines for UVA or UVC, to make it one day to generate ozone and another day to use it for disinfection as UVC band lamp. In medium-pressure mercury-vapor lamps, the lines from 200–600 nm are present. UVB straling komt van de zon en hiermee maakt een reptiel de juiste hoeveelheid aan vitamine D3 aan, deze in combinatie met calcium kan worden omgezet in bruikbare stoffen voor de reptielen bot opbouw. 4 years ago. Let me know more information about this. pressure mercury mercury vapor layer Prior art date 1999-04-29 Legal status (The legal status is an assumption and is not a legal conclusion. High-pressure mercury-vapor lamps are those lamp commonly used for general lighting purposes. A lamp in which light is produced by an electric arc between two electrodes in an ionized mercury-vapor atmosphere; it gives off a bluish-green light rich in ultraviolet radiation. Mercury vapor lamps have found the greatest use in industrial applications and outdoor lighting, because of their low cost and long life, and lamp sizes of up to 1,000 watts. 2, which shows the spectral intensity of radiation of a mercury-vapor short-arc lamp made of undoped quartz glass with FIG. § The lamp will produce its maximum output when the mercury vapor pressure is approx. Standard Mercury Ultraviolet Lamps: Our UV curing lamps are medium pressure Mercury Vapor lamps that are fabricated from a pure grade of amorphous non-crystalline silicon dioxide (SiO2) with tungsten electrodes sealed in each end by experienced craftsmen on specialized lathes. The metal halogens are added to create specific wavelength lines of ultraviolet radiation to match the sensitivity of the photopolymer being exposed or dried. discharge lamp pressure mercury mercury vapor vapor discharge Prior art date 1985-07-15 Legal status (The legal status is an assumption and is not a legal conclusion. Also known as mercury lamp. Therefore, most mercury vapor lamps have a phosphor coating that alters the color temperature and improves color rendering to some extent. (A) Sodium vapor lamp (B) High pressure mercury vapor lamp (C) Low pressure mercury vapor lamp (D) Neon lamp. I have Mercury-vapor lamp emitting UV light. You mentioned three types of mercury lamp. Other HID types that offer higher LPW and better color properties have largely superceded the use of this lamp. 104106 N/m2. LAMPS (High Pressure Mercury Vapor Lamps). 80. A mercury-vapor lamp is a gas discharge lamp which uses mercury in an excited state to produce light.The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger borosilicate glass bulb. In essence, it is all about pressure. Low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. wavelength range of 248 to 1,014 nm Mercury Vapor Lamps a gas discharge lamp that uses an electric arc through vaporized mercury to produce light first high intensity discharge lamps to be commercially available. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) They emit primarily in the blue and green. The high-pressure mercury vapor (HPMV) discharge (pressure exceeding several atmospheres; efficiency of 20–25%) produces visible emission that is particularly deficient in the red spectral region. Metal halide lamps are mercury vapor lamps with the addition of metal halogens. See more » Argon. The lamps can be constructed to emit primarily in the UV-A (around 400 nm) or UV-C (around 250 nm). In fluorescent tubes ballast resistance is connected in series with the choke (A) when supply frequency is low (B) to reduce radio interference (C) when tube operates on dc supply (D) to reduce stroboscope effects. Comparing FIG. Handheld mercury vapor lamps have a power of 100W and ceiling-mounted devices have a power of 400W each. Reptielen UVB lampen zijn lampen die bij de meeste reptielen niet mogen ontbreken. 99 Expired - Fee Related Application number DE60012106T Other languages German (de) Other versions Do you need more details or a quote? UV lamp 5kw 365nm High Pressure Mercury Lamp No. 1 0. The power consumption assembly generates a large amount of heat, which causes the surface of the lamp to become hot, posing a burn hazard to the inspector. 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 to glow. Liquid mercury droplets collect at the lamp’s “cold spot.” Once the mercury droplets reach their peak temperature, maximum UVC output occurs. Argon is a chemical element with symbol Ar and atomic number 18. Suppose that a PES experiment is performed in which mercury vapor is irradiated with ultraviolet light of wavelength 58.4 nm. Mercury vapor lamps used in fluorescence microscopy usually have life spans of 300 hours, and as they approach the end of their life span, at 200 hours, exhibit output fluctuations primarily as a result of “discharge point shift” caused by cathode fatigue. One of the lines in the spectrum of a mercury vapor lamp has a wavelength of 254 nm. UVB is dan ook een must voor de zon aanbidders. Because mercury lamps are so prevalent in the current outdoor lighting infrastructure, and still safe when properly installed in a serviceable fixture, the need for these products will continue for many more years. II.C Phosphors for High-Pressure Mercury Vapor Lamps. Mercury-Vapor Lamp. The discharge also produces significant amounts of longer wavelength 365-nm UV radiation. 6 microns (.006 Torr). The outer bulb may be clear or coated with a phosphor; in eithe Mercury vapor lamp with lamp board for Samrtline (S200) and WellChrom (K200) fixed wavelength detectors.
