Low Pressure Mercury Uv Lamp

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.

Low pressure mercury uv lamp. Ushio germicidal lamps are low pressure mercury arc lamps that emit radiation peaking at 253 7nm uv c. New high power amalgam lamps are significantly more powerful than low pressure lamps. Medium pressure lamps produce the greatest uv output per unit length of lamp of the 3 lamp types. Often called germicidal or ozone absorption lamps they are very stable light sources.

Conventional uv lamps hold their mercury either in a liquid form more common in medium pressure lamps or an amalgam more common in low pressure high output lamps. Power supplies are. Even though more cleaning may be required for medium and amalgam lamp based systems because they have a smaller number of lamps in the uv unit these systems can. Home solutions germicidal uvc uv germicidal lamps low pressure mercury lamps compact our companies offer a superb line of uvc emitting compact germicidal lamps for applications in small spaces.

The low pressure uv lamps also called germicidal lamps exploit uvc light to get the rapid sterilization of bacteria molds fungi viruses and microorganisms both in air and in water in this category of lamps about 40 of electricity is converted directly into uvc radiation with monochromatic emission at 254 nm for germicidal applications and at 185 nm for the oxidation of surfaces. Designed by experienced engineers and by using quality material in combination with a tightly controlled manufacturing process we provide high quality lamps free of impurities to maintain strong and stable output throughout life of the lamp. Amalgam lamps use a mercury amalgam mix to control mercury vapor pressure. Amalgam uv lamps contain solid spots which consist of an alloy of mercury and another element such as indium or gallium.

As the main arc strikes and the gas heats up and increases in pressure the light shifts into the visible range and the high gas pressure causes. While looking for an appropriate uv lamp and unit for your home you wouldn t need something capable of treating a small river you need a unit that runs a low pressure uv lamp. These types of lamps are available in ozone producing and ozone free quartz with a variety of phosphors. Low pressure mercury vapor lamps are a highly efficient source of uv light particularly short wavelength uv light 254nm and 185nm.
