Low Pressure Mercury Uv Lamp

These lamps are consistently a favorite product among our clients.

Low pressure mercury uv lamp.

Power supplies are. 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. 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. New high power amalgam lamps are significantly more powerful than low pressure lamps.

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. Amalgam uv lamps contain solid spots which consist of an alloy of mercury and another element such as indium or gallium. Rather than a cold spot the lamp s amalgam spot on pellet regulates mercury vapor pressure during operation and yields up to three times the uvc output of a standard low pressure mercury lamp of the same length. Medium pressure lamps produce the greatest uv output per unit length of lamp of the 3 lamp types.

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. Amalgam lamps use a mercury amalgam mix to control mercury vapor pressure. 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. 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.

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. Low pressure mercury vapor lamps are a highly efficient source of uv light particularly short wavelength uv light 254nm and 185nm. Ushio germicidal lamps are low pressure mercury arc lamps that emit radiation peaking at 253 7nm uv c. 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.
