A lamp in which ultraviolet and yellowish-green to blue visible light is produced by an electric discharge through mercury vapor. The spectral lines from the mercury emission and the phosphorescence effect give a combined spectral distribution of light that is different from those produced by incandescent sources. Page 1. In Europe it has fallen out of fashion due to its relative inefficiency and rapid lumen depreciation by contrast with other light sources. The mercury vapor lamp is similar in construction to the sodium vapor lamp. Mercury vapour lamp is quite suitable for lighting applications. The Mercury lamp was the first kind of metal vapour light source that was mass produced for general lighting applications, and still today it remains one of the most popular discharge lamps produced globally. The 6035 Spectral Calibration Lamp produces narrow, intense lines from the excitation of Argon gas and Mercury vapor. The mercury vapor lamp was invented in the year 1901 by Peter (New York). 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. Facts About Aquafine Standard Low Pressure (LP) Lamps. The lamp gets its state of its operational stability. The mercury vapor ballast is a device that works with mercury vapor lamps. LP lamps operate at about 40°C and have one useful disinfection output peak at 254nm. COM. This mercury light bulb has a compact design so it can be easily transported and well preserved so it doesn’t break during shipping to the user. Spectrum - UV in more detail. Finish: Coated. Mercury lamps get dimmer over time and rarely burn out, so it is wise to replace them and restore light level. The arc in a high-pressure mercury vapor lamp (HPMV) produces lines of varying energy in the ultraviolet, blue and yellow portions of the spectrum. Do not operate the high-pressure mercury vapour lamp continuously for longer than 10 minutes.
