Lamps that produce light as a result of an electrical discharge, generated by an induction coil, in a low-pressure mercury vapor that is contained in a transparent tube or vessel whose inside is coated with fluorescent powder that converts the ultraviolet part of the emitted radiation from the discharge in visible light.

Induction Lamps

Induction lamps, like fluorescent lamps, belong to the family of low-pressure mercury gas discharge lamps. Unlike other discharge lamps they have no electrodes, which is why they are also called “electrodeless lamps” [2, 3]. The consequence of having no electrodes is a very long economic life of around 60,000–75,000 h. This long life is also the main feature of induction lamps. They find their application in situations where lamp replacement is near impossible or very expensive.

Working Principle

In an induction lamp, the free-running electrons needed for the gas discharge are obtained by...
