Lead-in-Wires

Lead in Wire

GEM manufactures a wide range of lead-in-wire types to satisfy the requirements of the lighting and related industries. The function of lead-in-wire in electric lamps is to provide an electric connection to the filament along with a glass-to-metal seal component. Wherever necessary, a built in fuse link is also available within a lead-in-wire pair. The lead-in-wire types manufactured covers a wide range of dimensions and materials to suit the many applications and lamp types.

These can be divided into distinct categories:
Lead-in-Wire Type Typical Application
Single Length Compact Fluorescent Lamps (CFL)
2 Part Halogen, Neon Indication and Glow Lamps
3 Part Standard Fluorescent Lamps (FTL), General Lighting Service Lamps (GLS), Compact Fluorescent Lamps (CFL)
4 Part Specially Joined High Wattage lamps, Discharge lamps

Within each category there are many standard types, which cover the majority of lighting industry requirements, and these are summarized in the following data sheet. Requirements outside these standard dimensions and materials can also be made available.

The lead-in-wires are made by Percussion Electric or Gas Welding techniques, depending upon the volume and the materials.

Quality

In all cases the lead-in-wire leads are made with focus on the following critical dimensions within customer specified limits:

  • Weld Strength
  • Dimension
  • Weld Diameter
  • Concentricity and Straightness

Continuous in-process inspection and final inspection ensures the highest quality level.

Packaging

Leads are generally supplied in standard flat-pack cardboard boxes or standard plastic / cardboard tubes. Special packaging as per customers requirements can also be accommodated.

Broad Specifications

Lead in Wire Specifications

Lead-in-wires are produced by welding three wires - namely; the Inner Lead (which supports the filament), Press or Seal (which provides the glass-to-metal seal), and the Outer Lead (which is directly connected to the power source).

The following table gives broad specification and manufacturing ranges of the lead in wires in general. Please contact us for more detailed specification of the lead in wires wires.
