High Pressure Mercury Lamp Uses

Low pressure mercury vapour lamp hg 2 lamp.

High pressure mercury lamp uses. There are two kinds of sodium lights. A sodium vapor lamp is a gas discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm. Mercury vapor lamps were the first high intensity discharge lamps to be commercially available for a wide variety of lighting applications. 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.

They emit primarily in the blue and green. Low pressure and high pressure low pressure sodium lamps are highly efficient electrical light sources but their yellow light restricts applications to outdoor lighting such as street lamps where they are widely used. The lamp works by creating an electric arc through vaporized sodium metal. Mercury vapor lamps are gas discharge lamps that uses an electric arc through vaporized mercury to produce light.

Two varieties of such lamps exist. Low pressure lps and high pressure hps. These lamps are mostly used for street lighting as well as industrial uses. Most models produce a bluish white light.

The lamps can be constructed to emit primarily in the uv a around 400 nm or uv c around 250 nm. High and low pressure uv mercury vapour lamps heraeus manufactures low and high pressure mercury vapour lamps used for applications such as photochemical processing fluorimetry mercury analysers medical and environmental equipment and fixed wavelength detectors. The mercury vapor lamp is a high intensity discharge lamp.
