Web9 aug. 2024 · Low-pressure mercury lamps (emitting UV light at 253 nm.) Ultraviolet light-emitting diodes (UV-C LEDs), which emit selectable wavelengths between 255 and 280 nm. Low-pressure mercury-vapor lamps usually have a quartz bulb in order to allow the transmission of short wavelength light. If synthetic quartz is used, then the transparency of the quartz is increased further and an emission line at 185 nm is observed also. Such a lamp can then be used for ultraviolet … Meer weergeven A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light. The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger Meer weergeven The mercury in the tube is a liquid at normal temperatures. It needs to be vaporized and ionized before the lamp can produce its … Meer weergeven For placements where light pollution is of prime importance (for example, an observatory parking lot), low-pressure sodium is … Meer weergeven The arctube of mercury lamps produces large amount of short wave UV-C radiation which can cause eye and skin burn. Usually the … Meer weergeven Charles Wheatstone observed the spectrum of an electric discharge in mercury vapor in 1835, and noted the ultraviolet lines in that spectrum. In 1860, John … Meer weergeven 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 … Meer weergeven In the EU the use of low efficiency mercury vapor lamps for lighting purposes was banned in 2015.
