Standard incandescent lamps include a filament of tungsten.

Tungsten filament lamps for domestic and similar general lighting purposes

Tungsten filament, also called tungsten evaporation coil, is of many metal shapes and generally consists of one or several streams of doped tungsten wires.

The Light Source is a gas filled tungsten filament lamp.

The molybdenum strips (4), the tungsten filament (3) and the molybdenum bracket (2) are enclosed in the bulb shell.

In 1904, a tungsten filament was shown to be more efficient and longer lasting than the carbonized bamboo filament used previously.

In 1904, a tungsten filament was found to be more efficient and longer lasting than the carbonised bamboo filament used previously.

In 1904, the tungsten filament was more efficient and more durable than the previously used carbonized bamboo filament.

The invention relates to an improved halogen lamp with a high working temperature based on a tungsten filament comprising rhenium.

We can find the tungsten filament techniques and the equivalence in LED technology.

Then a rhenium-tungsten filament is formed, which has a metastable crystal structure and can be better used in the halogen incandescent lamps.

An efficient halogen tungsten bulb with high light efficiency comprises a bulb shell, a molybdenum bracket (2), a tungsten filament (3), molybdenum strips (4), and molybdenum filaments (5).

The carbon has been replaced by a more heat resistant tungsten filament.

In the particle beam generating assembly, a cloud of particles, for example, electrons, are generated by heating at least one tungsten filament.

Tungsten filament is packed in plywood case and sent by ocean or air.
