Low Pressure Mercury Vapour Lamp

Mercury vapor conducts electricity completing the circuit.

Low pressure mercury vapour lamp.

As pressure increases the chance of multiple collisions gets increased. Active 5 days ago. Low pressure lp amalgam low pressure lp and medium pressure mp lamps are all mercury based lamps. Fused silica is used in the manufacturing to keep the 184 nm light from being absorbed.

Low pressure mercury vapour lamp hg 2 lamp heraeus has developed a compact low pressure low voltage mercury vapour lamp type hg2 principally for use in scientific instrumentation. Low pressure mercury vapor lamps do they always produce both 184 5nm and 253 7nm. Often called germicidal or ozone absorption lamps they are very stable light sources. This lamp has a highly stable output predominantly at the 253 7 nm mercury line.

What s the difference between low pressure lp amalgam low pressure lp and medium pressure mp uv lamps. In medium pressure mercury vapor lamps the lines from 200 600 nm are present. Viewed 18 times 0 begingroup closed. One would tip the lamp and electrical contacts on each side of the lamp would send electricity through a liquid mercury which started the lamp.

Closed ask question asked 5 days ago. A mercury vapor lamp whose partial pressure during operation does not exceed 0 001 atmosphere. Again transition of the electrons requires least amount of input energy from a colliding electron. 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.

These types of lamps are available in ozone producing and ozone free quartz with a variety of phosphors. Fluorescent and germicidal lamps are included in this. Find out information about low pressure mercury lamp. Explanation of low pressure mercury lamp.

Amalgam lamps use a mercury amalgam mix to control mercury vapor pressure. Looking for low pressure mercury lamp. This question is off topic. The first mercury vapor lamps were in a lower pressure tube.

It is not currently accepting answers. In low pressure mercury vapor lamps only the lines at 184 nm and 254 nm are present. Lamp output in the uv range depends on the amount of mercury and vapor pressure of mercury in the lamp.
