The basic construction of neon lamps is shown in figure :

The bulb is made of glass sealed in two areas, the pip and the pinch. In the pinch area, the leads protrude through one end of a glass tube and the glass is heated and pinched about the leads.

This holds them in position and forms a hermetic seal.

The leads are made from a special material known as dumet which is a low resistance material consisting of a copper sheath around a nickel iron core constructed so that its expansion coefficient is the same as that of the glass used for the bulb.
