1.5 UV lamp types
UV lamps (ultraviolet) radiate optical radiation in, among others, the range between 200 nm and 400 nm on
which the name "UV lamp" is also based. Low pressure (incl. Amalgam) UV lamps produce UV radiation
with a wavelength of 253.7 nm where medium pressure UV lamps radiate at a wide spectrum of
wavelengths (see graph with spectral data). Depending on the type of UV lamp, energy is also emitted in
the visible area of the electromagnetic spectrum:
-
Low pressure (LP) UV lamps: blue light (400 nm)
-
Low pressure (LPHO) UV lamps: blue light (400 nm)
-
Amalgam UV lamps: blue light (400 nm)
-
Medium pressure (MP) UV lamps: white light (400 nm - 750 nm)
UV lamps contain a small amount of mercury that is responsible for the UV radiation produced.
A properly working UV lamp needs a certain operating temperature in order to function reliably and
efficiently, with the lamps used in the VGE Pro UV series these temperatures are as follows:
-
Low pressure (LP) UV lamps: approximately 45 °C
-
Low pressure (LPHO) UV lamps: approximately 45 °C
-
Amalgam UV lamps: approximately 95 °C
-
Medium pressure (MP) UV lamps: 600 °C - 900 °C.
