In medium-pressure mercury-vapor lamps, the lines from 200–600 nm are present. 1901 - The First Commercial Mercury Vapor Lamp Peter Cooper Hewitt (New York City) had a history of innovations in other fields, and when he set about on the project of the mercury vapor lamp in 1898 it only took 3 years to develop the first reliable lamp with a acceptable color of light. Introduction. A PolarLites 100 watt mercury vapor lamp starting up with a 70 watt metal halide ballast (Ignitor disconnected). High pressure mercury lamp is also called UV curing lamp, with a spectral range between 350nm-450nm, such as 253.7nm, 303nm, 334nm, 365nm, 366.3nm, of which the wavelengths of 365nm and 366.3nm have great advantages. 0000003948 00000 n This is enclosed by an outer glass bulb that filters out harmful short-wavelength ultraviolet (UV) radiation. in a vivarium - the lamp is creating a zone, at 30cm distance, that to surface distance = 30cm) It consists of 2 electrodes made up of an alloy of tungsten which is placed together in a medium containing mercury vapor and 25-50 torr of pure argon gas.

There are two types of mercury vapor light bulbs sold in the U.S. 1. 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. A mercury-vapor lamp is a gas discharge lamp which uses mercury in an excited state to produce light.The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger borosilicate glass bulb. %%EOF 0000041343 00000 n meter readings and thermal gradient, spectral The bulb is comprised of an inner tube, called the arc tube, and an outer jacket (or bulb).
