High Pressure Mercury Lamp Uses

Mercury vapor lamps are gas discharge lamps that uses an electric arc through vaporized mercury to produce light.

High pressure mercury lamp uses.

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. 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. Low pressure lps and high pressure hps. They emit primarily in the blue and green.

Two varieties of such lamps exist. It uses an arc through vaporized mercury in a high pressure tube to create very bright light directly from it s own arc. There are two kinds of sodium lights. Low pressure mercury vapour lamp hg 2 lamp.

The lamp works by creating an electric arc through vaporized sodium metal. 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. Mercury lamps are still a legitimate and widely used hid lamp source mercury vapor lamps have found the greatest use in industrial applications and outdoor lighting because of their low cost and long life and lamp sizes of up to 1 000 watts. The lamps can be constructed to emit primarily in the uv a around 400 nm or uv c around 250 nm.

The mercury vapor lamp is a high intensity discharge lamp. Mercury vapor lamps were the first high intensity discharge lamps to be commercially available for a wide variety of lighting applications. 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.
