WebFig.4 Spectral Distribution of a Low-Pressure Mercury Lamp 3) (5) Low-Pressure Mercury Lamp. The low-pressure mercury lamp is a discharge lamp designed to have a low mercury vapor pressure (100 Pa max.) when lit to efficiently emit the mercury resonance lines (254 nm or 185 nm). Fig. 4 shows the spectral distribution of a low-pressure … Web1 jun. 1999 · Smaller than a pinched arc tube, a pulse-start lamp's arc tube uses an ignitor to create a high-voltage starting pulse, as does an HPS lamp. While both types of lamps use a mogul base, a pulse-start lamp's socket (and ballast) is incompatible with a pinched tube MH lamp's socket (and ballast), and visa-versa. (See Fig.4, in the original article.)
Mercury arc lamps
Did you know?
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 soda lime or borosilicate glass bulb. The outer bulb may be clear or coated with a … 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 Thomas Way used arc lamps operated in … Meer weergeven 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 … Meer weergeven In the EU the use of low efficiency mercury vapor lamps for lighting purposes was banned in 2015.
