Gas dosing with ultraviolet lamps

Ultralight is a company based in the principality Liechtenstein draws on its walth of experience in the field of development and production of ultraviolet lamps and components.

Challenge

The lamps are used in industrial applications of curing special UV reactive lacquers, glues and inks. The lamps emit according to the lacquers´ requirements in the UV-A by 400 nm to UV-C by 250 nm. Different noble gases are necessary for the production of the UV lamps.

Solution

The quantity of noble gases when filled is dosed during the manufacturing process under vacuum with the help of a piezo and Pirani combination gauge VSR53DL. Quantity and type of gas depend on the type of lamp and ranges between some 10 to 100 mbar absolute.
