Low Pressure Mercury Uv Lamp

Medium pressure lamps produce the greatest uv output per unit length of lamp of the 3 lamp types.

Low pressure mercury uv lamp.

Often called germicidal or ozone absorption lamps they are very stable light sources. Amalgam uv lamps contain solid spots which consist of an alloy of mercury and another element such as indium or gallium. 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. 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.

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

New high power amalgam lamps are significantly more powerful than low pressure lamps. 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. 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. Amalgam lamps use a mercury amalgam mix to control mercury vapor pressure.
