Infralight Technology are major suppliers of ultraviolet lamps and equipments. Infralight Technology have recently released the new longlige amalgam lamp for use in wastewater treatment systems. Infralight Technology supply amalgam ultraviolet germicidal lamps that deliver up to 3 times the UVC output (254nm) of standard low pressure UVC lamps.
The ultraviolet germicidal UV amalgam series from Infralight Technology is designed to operate efficiently at higher operating temperatures than standard low pressure and high output ultraviolet germicidal lamps. The benefits allow equipment manufactures to have a greater efficiency and lower equipment costs.
The ultraviolet UV amalgam series is a cost effective alternative to medium pressure lamps. Infralight Technology can also custom build lamps to provide the equipment manufacturer with an ultraviolet lamp that fits their equipment needs.
The vapour pressure of a normal low pressure lamp is governed by the temperature of the mercury: If the temperature falls, the irradiance or the amount of UV light transmitted falls. An amalgam ultraviolet UV lamp does not contain liquid mercury like a standard low pressure mercury discharge lamp.
In this type of ultraviolet UV lamp, the mercury is mixed or more correctly, alloyed with the principle metal Indium forming an amalgam of the two metals. The amalgam is not dispersed throughout the lamp as free mercury like a normal ultraviolet low-pressure lamp, but instead it is placed and fixed at two condensation points along the axis of the quartz tube.
This provides the optimum mercury vapour pressure at higher lamp temperatures, normally 80-85°C, and the amalgam bead or blob acts as a pressure regulator, releasing mercury into the vapour if the pressure falls, or conversely, absorbing mercury if the pressure rises. The result is that the net output of ultraviolet light remains constant.
