Lamp Production

Lamp Production

Unlike the currently popular LED lights, all sorts of traditional lamps contain a bulb or tube which requires evacuation during the production stage. The lamp volume either remains under vacuum or is recharged with special gases. Thus, vacuum pumps are necessary for producing all sorts of traditional lamps.

The required vacuum level depends on the type of lamp. Most often, pressures in the 10-2 to 10-3 mbar range are used, but some technologies require an even lower high-vacuum pressure range.

Leybold offers numerous types of suitable fore- and high vacuum pumps in their product portfolio. Typically, oil-sealed, two-stage rotary vane pumps are used. Here we have the robust “work horse”, the TRIVAC B, the low-cost TRIVAC T and the compact SOGEVAC NEO D with integrated exhaust filtration available. To achieve high vacuum, we also offer a full line of mechanical and magnetic levitated turbo-molecular pumps (TMP).
