High Pressure Mercury Arc Lamp

A xenon arc lamp is a highly specialized type of gas discharge lamp an electric light that produces light by passing electricity through ionized xenon gas at high pressure.

Mercury lamps may 11 2017. It produces a bright white light that closely mimics natural sunlight with applications in movie projectors in theaters in searchlights and for specialized uses in industry and research to simulate sunlight often for. Jelight company also produces super high pressure mercury lamps or short arc lamps. These high intensity uv line sources are specifically designed for pcb.

Liquid mercury droplets collect at the lamp s cold spot once the mercury droplets reach their peak temperature maximum uvc output occurs. It was developed by philips in 1995 for use in commercial projection systems home theatre projectors md ptvs and video walls. 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. 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.

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. The mercury vapor lamp is a high intensity discharge lamp. 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. 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. Their unique uv emission spectra make them popular for unique applications that need enhanced uv output such as uv spectroscopy uv curing and other industrial processes and environmental. Super high pressure mercury capillary flash lamps are used in a variety of applications due to the fact that they provide a high intensity source of both visible and ultraviolet radiation. 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.

The ultra high performance lamp a high pressure mercury arc lamp often known by the philips trademark uhp was originally known as the ultra high pressure lamp because the internal pressure is as much as 200 atmospheres. Ushio specializes in the manufacturing of high quality value added led quartz halogen fluorescent and compact fluorescent metal halide and high pressure sodium products. 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. Mercury hg arc lamps are ideal light sources for applications that require high intensity spectral lines emitted in the deep uv to visible light regions.
