. Mercury lamps get dimmer over time and rarely burn out, so it is wise to replace them and restore light level. Required fields are marked *. Arc discharge takes place in a transparent tube inside a larger bulb of glass. . Mercury Vapor lamps feature low initial cost, but have higher operating costs than HPS or Metal Halide due to its lower efficiency. . (self-ballasted) Low pressure mercury lamps have been manufactured in Jelight Company Inc. since 1978 for a variety of applications such as: HACH Replacement UV for TOC Analyzers, Arc imaging, Chromatography, Photochemistry, Calibration of UV Detectors, Calibrations of Spectrophotometer, and more. The outer bulb reduces the ultraviolet radiation of the inner arc tube. Ultraviolet high pressure mercury lamps are high intensity gas discharge lamps. Mercury Vapor Standard. In medium-pressure mercury-vapor lamps, the lines from 200–600 nm are present. . Applications. • Landscape . There are distinct advantages of mercury lamps when compared to many other light sources; Save my name, email, and website in this browser for the next time I comment. High-pressure mercury-vapor lamps are those lamp commonly used for general lighting purposes. If a lamp breaks, ventilate the room for 30 minutes and remove the parts, preferably with gloves. Standard lamps and Custom OEM development is available. Utility Lighting Products, Understanding LM-80: Measuring Lumen Maintenance of LED Light Sources, Retrofitting Existing HID lamps to LED Technology, Total Cost of Ownership in Lighting – Part 2, Advantages and Applications of Mercury Vapor Lamps. The rated average life of self-ballasted mercury vapor lamps range from 12,000 to 16,000 hours and light output is 14 to 24 lumens per watt. • Home Garages & Decks HPL High Pressure Mercury. All outdoor applications, factories, transport sector and industrial area lighting. • Warehouse. The UHP lamp (ultra high pressure lamp, usually mercury arc) refers to projector lamps with an internal pressure of over 3000 lbs per square inch. Further improvement is achieved in many of the lamp types by the addition of a phosphor coating to the inside surface of the outer bulb. Compact lamps are available in a specially engineered two-tube linear innovative design, which allows a very uniform output. • “T” type light bulbs have a self-extinguishing feature that shuts off the light within 15 minutes after the outer bulb is broken. Radiation from the Mercury arc is … High pressure mercury vapour lamp with elliptical bulb, coated, base E40. . Best Applications • Available in a wide variety of ratings, colors, sizes and shapes . For use with control gear designed for high-pressure mercury lamps. High performing lamps are used in applications such as Scientific Illumination, Tanning, UV Curing and Sterilization/Disinfection. . It’s particularly important that the supply voltage matches the operating voltage specified on a self-ballasted lamp. • Exceptional Service Life; Typical lamp life exceeds 24,000 hours (standard mercury lamps) of continuous service with many achieving up to 40 years of daily regulated service Mercury vapor lighting is the oldest HID technology. • Parking Areas • Post Tops . The invention relates to a high-pressure mercury vapor discharge lamp ( 1 ) with an envelope ( 2 ) made from high-temperature-resistant material, which contains two electrodes ( 12, 13 ) made from tungsten and a filling in a discharge space ( 14 ), which filling essentially consists of mercury, rare gas, and a halogen that is free in the operating condition. Applications of capillary super-high pressure mercury vapourlamps . The clear mercury bulb has a bluish green appearance and the Deluxe White has a higher color rendering. Conversely, in landscaping applications, they make plants and trees look extremely rich and vibrant, as they bring out the green color of foliage beautifully. This is different from fluorescents which use the mercury vapor arc to create a weaker light that mainly creates UV light to excite the phosphors. High pressure mercury vapour lamps consist of a quartz discharge tube encased in a glass bulb coated internally with a fluorescent phosphor which converts the UV radiation emitted by the tube into visible light, particularly at the red end of the spectrum which older style mercury vapour lamps lacked. 50 lumens per watt and website in this class of lights are what give their.
