Aside from the theories about pyramids harvesting static electricity, transmitted via long-ago-stolen gold cables, there's that infamous carving of what look like light bulbs, and the anecdote about glass columns that initially glowed when discovered by an archaeologist, who broke one and found mercury in it.

High-pressure mercury vapour lamps are the oldest high-pressure lamp types, being replaced in most applications by the metal halide lamp and the high-pressure sodium lamp. Fits into a standard ceramic socket (No ballast needed). As of February 2018, "External links modified" talk page sections are no longer generated or monitored by InternetArchiveBot. Historically, the most common method of generating UV radiation involves the use of a Low Pressure (LP) mercury vapour continuous wave lamp with … The 400W lamp shown here has mercury and some other elements added to the arc to produce a bright green light.

The EU wants to ban them because they contain large amounts of mercury and are not efficient like fluorescent bulbs. The Effects of Mercury Vapour Pressure The spectral power distribution of the mercury discharge depends to a very great extent on the pressure at which it is operating. I will also try to get a picture. The lamps can be constructed to emit primarily in the UV-A (around 400 nm) or UV-C (around 250 nm). To fill out this checklist, please add the following code to the template call: The spectrum has been replaced to a version with several lines (so probably high pressure), but it still does not correspond to what is expected from the atomic emission spectrum of Mercury.

Lamp that produces light as a result of an electrical discharge, generated between two electrodes, in a high-pressure mercury vapor that is contained in a transparent bulb. I can still see red and blue colors in low pressure sodium lamp light. The 160 Watt projects UVB up to several feet from the lamps surface and is ideal for large terrariums or bird aviaries. a gas-discharge light source in which an electric discharge in mercury vapor is accompanied by optical radiation in the ultraviolet, visible, and near-infrared regions of the spectrum. If I'm wrong, the amalgam article should give an example of a compound amalgam, such as sodium iodide amalgam. (�. 0000001140 00000 n
After many many years some lamps simply went out because the emitting layer on the tungsten electrodes is totally depleted and the electrode is no longer capable to emit enough electrons to sustain the discharge. High-pressure mercury-vapor lamps are those lamp commonly used for general lighting purposes. The mercury and argon is kept inside a quartz arc tube, which is surrounded by a wonderfully insulated borosilicate glass bulb. But this article implies that there is such a thing as sodium iodide amalgam. In my opinion is wrong: cycling is the end of life behaviour of high pressure sodium lamps. Helium in amber glass glows gold; blue light in yellow glass shows green; combinations of gases give white light.… Peter Cooper Hewitt …electrical engineer who invented the mercury-vapour lamp… Hg-lamp: you excite the Hg atoms, which yields a very ‘discrete’ spectrum.

", Relevant links here: It uses an arc through vaporized mercury in a high pressure tube to create very bright light directly from it's own arc. In some versions, fluorescent powder is applied that converts the ultraviolet part, which is emitted together with visible light, into visible light to improve the color quality of the light. My understanding has been that the power consumption stays roughly the same while light output drops substantially. Alison Chaiken 02:03, 3 February 2006 (UTC). As it emits light on only one wavelength, it is the easiest to filter out. To facilitate starting of the lamp, a third electrode is mounted near one of the main electrodes and connected through a resistor to the other main electrode.

You could say that a fluorescent lamp is also a sort of Mercury-vapour lamp. In some bulbs, the ultraviolet light shines on phosphors which make white light from it, although not all mercury-vapor lamps use phosphors. The mercury vapor lamp is in the category of the gas discharge lamp, these operate by an electric arc using vaporized whatever (in this case, mercury) to produce light.

At low pressures the output is predominantly in the ultra-violet, but as pressure increases self-absorption here results in the visible green, yellow and violet lines becoming relatively stronger. In the intervening 8 years LED lamps seem to have taken over from the far less efficient halid lamps.
